What is turnstile mechanism?

In recent years, with the rapid development of the security market and the wide application of intelligent pedestrian turnstile gate, tripod turnstile, swing turnstile, flap barrier turnstile, full height turnstile, sliding turnstile, and speed gates have been well known. Maybe we don’t care much about the quality of its mechanism, but will pay more attention to its appearance, price, and other aspects, but it is very important for users to have a good turnstile gate mechanism.

The turnstile mechanism is a whole composed of various mechanical parts inside the pedestrian turnstile gate (including the driving motor, reducer, gear, belt, electromagnetic device, etc), which uses the mechanical principle to control the opening and closing action of the turnstile gate blocking rod(blocking barrier). It is the key for the pedestrian turnstile gate to realize the functions of fast passage and anti tailing.

The turnstile mechanism is the core component and important part of the turnstile gate, and the turnstile mechanism controls the turnstile gate by controlling the swing of the blocking rod arm, which is equivalent to the heart of the turnstile gate. The operation principle of the turnstile gate is to control the opening and closing of the blocking rod by controlling the operation and stop of the mechanism, so as to realize the access control management function.

This video mainly shows some turnstile gate mechanisms of our factory. In the area where the turnstile gate mechanism is placed, our colleagues showed each turnstile gate mechanism in detail and showed every detail of the turnstile gate mechanism from all angles. The first is a fully automatic tripod turnstile mechanism. With people’s higher and higher requirements for security equipment, more and more customers will also adopt more high-end fully automatic tripod turnstile gate mechanisms.

Then you can see that the semi-automatic full-height turnstile mechanism is placed on the whole floor below. It can be seen that this semi-automatic full-high turnstile mechanism adopts good manufacturing technology, and the whole appearance is clean, tidy, and atmospheric. It is this high-end and high-quality full-high turnstile mechanism that determines the smooth operation and service life of the full-high turnstile gate Then the video also shows the flap barrier turnstile movement, sliding turnstile mechanism, and swing turnstile mechanism. Finally, a commonly used semi-automatic tripod turnstile mechanism is shown.

full height turnstile mechanism

The key factors affecting the performance and service life of the turnstile mechanism include the processing technology and material of mechanical parts, as well as the most important driving motor and the supporting reducer.

The drive motor usually adopts a DC brush motor or DC brushless motor. DC brush motor has low cost and simple control technology, so it is widely used by many pedestrian turnstile gate manufacturers. However, the carbon brush is a vulnerable and consumable part, which needs regular maintenance and replacement. A brushless DC motor has no carbon brush, so there is no such loss and its service life is long.

If you want to improve the performance and service life of the turnstile mechanism, it is a good choice to use the brushless DC motor with better performance and longer service life, especially the brushless DC motor of the first-line brand in Europe. Its reliability and durability can not be achieved by ordinary motors, but the cost is relatively high and the control technology is very complex.

Types of Turnstile mechanism:

Before we start, you need to know different types of turnstile mechanisms, Maybe others will define or distinguish different types of turnstile mechanisms from other aspects. The turnstile gate mechanism provided by MairsTurnstile includes a tripod turnstile gate mechanism, swing turnstile gate mechanism, flap barrier turnstile mechanism, and full height turnstile gate mechanism. The design and improvement of the turnstile gate mechanism are very important for the improvement of the overall stability, quality, and humanized function of the pedestrian turnstile gate. Let’s briefly introduce types of turnstile gate mechanisms:

Full height turnstile mechanism

The full height turnstile gate mechanism is divided into a semi-automatic full height turnstile gate mechanism and an automatic mute full height turnstile gate mechanism.

The semi-automatic full height turnstile gate mechanism controls the opening and closing of the machine through the solenoid valve. Through continuous improvement, the solenoid valve is equipped with a heat dissipation device, the service life is prolonged, the shock absorber is integrated, the collision sound is reduced, and the mechanical anti reversal function is improved on the basis of the electromagnet movement, which can realize the anti reversal and buffer functions;

Its disadvantage is that there is a certain amount of noise. Because of its good performance and ultra-high cost performance, most of the full heights in the market currently use this semi-automatic full height turnstile gate mechanism.

The fully automatic mute full height turnstile gate mechanism is realized by using the motor combined with the special-shaped grooved wheel structure. When passing, it automatically rotates forward at a certain angle, and people touch the blocking rod to pass. It is a brand-new product completed by using the industrial control processing method. During the whole product operation, the start and stop are very stable, and the braking and locking can be realized quickly. It is the first mute full height turnstile gate mechanism combined with multi-channel and multi-level sensors in the industry. It has the advantages of no noise, stable operation, no mechanical wear, and long service life. Its disadvantage is that the cost is relatively high.

If you want to view the full-automatic full height turnstile gate mechanism, you can view the video at the end of the article, which contains the display of this full-automatic full height turnstile gate mechanism.

Tripod turnstile mechanism

The tripod turnstile gate mechanism is divided into a semi-automatic tripod turnstile gate mechanism and a fully automatic silent Tripod turnstile gate mechanism. The semi-automatic tripod turnstile gate mechanism is mainly composed of the main shaft, electromagnet, toothed cam, positioning cam, travel switch, damper, tension spring, and rod dropping equipment, which has the advantages of low cost and simple mechanical structure. However, due to the influence of mechanical structure, the service life is not long, and it is often affected by independent impact with high noise.

When the tripod turnstile drive plate (hereinafter referred to as the drive plate) receives the opening signal, one relay is closed and the corresponding electromagnet is turned on, which promotes the shortening of the lock arm and eliminates the determination of the toothed cam. At this time, pedestrians can pass in the direction exempted from a determination by pushing the push rod slightly.

The fully automatic mute tripod turnstile gate mechanism is mainly positioned by the sensor. There is no mechanical impact during operation. The overall structure conforms to the basic principle of mechanics and has no noise. Tripod turnstile gate mechanism with long service life and high technical requirements for the control part.

Flap barrier mechanism

The flap barrier turnstile mechanism is the core of the whole flap barrier gate. The operation quality of the flap barrier mechanism determines the quality of the flap barrier gate. At present, the relatively high-end high-precision casting mechanism adopts the latest arms control technology on the basis of the mainstream full height sliding turnstile gate, which has the characteristics of no noise, stability, no mechanical wear, and long service life. Of course, the correct use method and proper maintenance are also the keys to the service life of the flap barrier turnstile mechanism.

The flap barrier turnstile mechanism can be divided into a full-height mechanism and a half-height mechanism. The full height mechanism is better than the half-height mechanism. The superiority of the mechanism largely determines the superiority of the same type of pedestrian turnstile gate. The stability and use effect of the full height mechanism is very perfect. The flap barrier turnstile produced by Mairs adopts a full-height mechanism, just to bring you the best traffic experience.

Swing turnstile gate mechanism

The swing turnstile gate mechanism can be roughly divided into a brushless motor and a servo motor. The difference between a servo motor and a brushless motor lies in whether there is a commonly used brush commutator. The servo DC motor converts the current direction by touching the graphite brush with the annular commutator installed on the rotor. Swing turnstile using a brushless motor, the rotor position is transmitted to the control circuit through the Hall sensor, so that the accurate time of motor phase commutation can be obtained.

When the swing turnstile gate is equipped with a brushless motor, three Hall-effect positioning sensors can work at the same time. Because there is no brush, the brushless motor runs more stably, has no noise, the body will not shake, the friction between the swing arms and the chassis body is reduced, and has a longer service life than the brush motor.

Working principle and function:

what’s the working principle and function of the turnstile mechanism, Mairs will show you a brief introduction.

The turnstile gate machine swings through blocking rods to form the access entrance gate. The turnstile gate is retracted to allow pedestrians to pass. Whether it is opened or retracted, there will be two fixed points, namely, the upper and lower fixed points. When the turnstile gate reaches the upper fixed point, the gate cannot be opened by horizontal external force and people are not easy to cross. For safety reasons, the turnstile mechanism has a mechanical anti-pinch, No matter whether it is opened or closed, when the turnstile gate encounters an external force effect (less than 3N. M), the mechanism will slip in place, which has a safety maintenance function for repairmen and pedestrians.

Generally speaking, the working principle of the turnstile mechanism is that when the turnstile gate controller receives the traffic signal, it will give the turnstile mechanism the signal command to open the gate. The turnstile mechanism completes the control of the blocking rod arm, so as to realize the personnel traffic management.

Security turnstiles gate is used more and more in real life. As a professional security turnstiles gate manufacturer, Mairsturnstile has continuously improved the turnstile mechanism, through the continuous improvement of the turnstile mechanism, improving the stability and increasing safety as the premise, I have experienced the initial development of the first generation of turnstile mechanism, improved the second generation of turnstile mechanism, and then developed the optimized structure of the third generation turnstile mechanism to improve the quality.

As we all know, the engine is the heart of the car, then the mechanism is the heart of the security turnstile gate. The stability of the turnstile mechanism directly determines the quality of the user in the process of using the security turnstiles gate. Every time Mairsturnstile engineers continuously improve the turnstile mechanism and optimize the structure, it is to better improve the product quality, our goal is customer first so that user satisfaction can be increased to 99%.

The turnstile mechanism is one of the core components of the turnstile gate, and the turnstile mechanism controls the turnstile gate by controlling the swing of the rod arm.

The mechanism of the turnstile gate is the core of the whole turnstile gate. The operation quality of the mechanism determines the quality of the turnstile barrier gate, but the failure of the turnstile gate is also related to the mechanism. Only the correct use method and proper maintenance are the keys to ensuring the service life of the turnstile gate. It is also a method to improve the overall service life of the turnstile gate, following Mairsturnstile to correctly understand the turnstile gate mechanism. 

Turnstile mechanism through different process treatment, the performance of the mechanism is also different, What is the treatment process of the turnstile mechanism by Mairs?

Turnstile Mechanism Process

By frequency quenching, the core gear has high wear resistance and high toughness on the surface, and the spindle has HB220-280°tempering treatment, increasing wear resistance and impact resistance, and has strong mechanical properties. The external structure of the core adopts electroplating and baking paint to enhance the corrosion resistance of the surface. Mairsturnstile thinks the process of turnstile gate mechanism is very important, so the turnstile barrier gate has the characteristics of stable use, low noise, long service time and so on which is deeply loved and trusted by customers.

Structure of turnstile mechanism

First, the external structure of the turnstile mechanism, that is, the appearance of the mechanism at the first sight. The external structure of the turnstile gate mechanism needs to enhance the corrosion resistance and safety of the surface due to its unique properties. Two conventional methods are paint baking and electroplating. The exposed transmission part of the gate is added to the shield, which makes it look compact and reasonable.

Second, the internal structure of the turnstile mechanism, that is, the key technology that dominates the quality of the whole security turnstile gate. Key technologies determine success or failure. There are many kinds of structure, the most common is belt drive and gear drive. Belt transmission, as the name implies, is realized by belt transmission. Belt transmission needs to be paid attention to. When the belt tension is tight, the slip coefficient is small, the transmission efficiency is high, and the speed of opening and closing the door will be very slow.

Under the long time use of the machine core, the belt adjustment will slowly become loose, the tension is small, so the slip coefficient will increase, and through the heat expansion and contraction of the belt, the speed of the skid is not easy to control, so it is easy to hurt people. Gear drive As the name implies, it is driven by a tooth sucker, the tooth surface has high wear resistance and impact resistance, mechanical properties enhanced.

After heat treatment, the gear HRC55-60°high frequency quenching, gear wear resistance is higher. When gear transmission, there will be some noise, usually reduce noise, just use rolling bearings in the rotating eccentric wheel to improve the axial runout. Usually, the manufacturing cost of gear transmission is high and the stability is good.

At present, it is the choice of some high-end turnstile gate manufacturers. Generally speaking, the technology determines the success or failure, and the quality of the mechanism directly determines the stability and safety of the turnstile gate, and Mairsturnstile focuses on all kinds of face recognition turnstile gates, ticket integrated turnstile gates, station special turnstile gates, scenic area special turnstile gate research and development and production.

The function of turnstile mechanism:

1. Has the function of reading card memory, the user can set the controlled port to read the card many times or single read the card.

2. Has the function of automatic reset, the system will automatically cancel the user’s permission when the pedestrian does not pass within the specified time after reading the card effectively.

3. Has the function of automatic opening of power off to meet the requirements of fire fighting passage.

4. Has a unified standard external electrical interface, can be connected with a variety of card readers, and can be remotely controlled and managed through the management computer.

5. Accurate logic to judge the speed door mode, and anti-tailing function, can distinguish the size of objects when the flow of people will not occur false alarm and misjudgment.

6. Sound, and light alarm function: including illegal intrusion, and trailing alarm.

7. Can be connected with a variety of card reading, and recognition (face, fingerprint, etc.) equipment to receive relay switch signal work.

Single-core turnstile and Double core turnstile

What is the difference between a single-core turnstile and a dual-core turnstile? The difference between a single-core turnstile and a double-core turnstile is often mentioned by users. Today, let’s briefly explain:

Single-core turnstiles and double-core turnstiles are distinguished from the point of view that the turnstile gate has a number of mechanisms. A single-core turnstile has one turnstile of equipment with one mechanism that controls one-way traffic, and a double-core turnstile has two mechanisms to control two-way traffic and shares one turnstile gate equipment.

In fact, the obvious difference is that the single-core turnstile has only one blocking rod and the double-core turnstile has two blocking rods. Two single-core turnstiles form one turnstile gate passage or channel, and one double-core turnstile and two single-core turnstiles form two turnstile gate passages or channels. Two dual-core and two single-core turnstile gates form three turnstile gate channels, and so on;

If an installation place is designed in this way, the budget cost can be saved. However, if it is installed at two entrances and exits in the same office location and two passages or channels are required, four single-core turnstile machines have to be used, and two are combined into one turnstile passage or channel.

In other words, the single-core turnstile gate is used for single-channel and multi-channel, and the double-core turnstile gate is used for multi-channel. This has nothing to do with one-way traffic and two-way traffic because the traffic direction is completed by setting, not by several turnstile gates.

Maintenance of turnstile mechanism:

The main performance of the turnstile gate mechanism is reflected in safety, long life, stability, supporting high-speed opening and high-speed stopping, and easy maintenance. Therefore, we must pay attention to the maintenance of the turnstile gate mechanism and improve the service life of the product.

1. Regular maintenance of turnstile mechanism method: cut off the power supply, open the swing barrier gate machine cover, clean the surface dust, clean the transmission part first, and then add butter, swing barrier gate entrance guard gear, and wheel slot should also be properly coated with butter.

2. Regular check items: check each fastener, and connecting rod for loose condition, and tighten it.

3. Swing barrier gate breakable parts maintenance: check the wear of the breakable parts, the swing barrier gate positioning arm and positioning disc to have more than 3 mm clearance timely replacement, normal clearance (1-1.5 mm), in the solenoid valve spool appropriate butter, so that solenoid valve in the left and right movement to reduce resistance, lubrication, pay attention not to add too much, to moderate.

Pay attention to the swing barrier gate limit switch and limit plate do not adjust casually, in case too far or too close to cause an error.

Video of Turnstile Mechanism:

This video shows two kinds of flap barrier turnstile mechanisms from various angles, three kinds full height turnstile gate mechanism, a tripod turnstile gate mechanism, a swing turnstile gate mechanism, and a semi-automatic tripod turnstile gate mechanism. A high-quality turnstile gate mechanism determines the stable operation and service life of the pedestrian turnstile gate.

We can see that the video shows three kinds of full height turnstile gate mechanisms respectively. The first two are semi-automatic full height turnstile gate mechanisms, corresponding to 90-degree full height turnstile gate and 120-degree full height turnstile gate respectively. The other is a full-automatic full-height turnstile gate mechanism. Some customers need these full height turnstile gates to be used in high-end places and need more expensive full height turnstile gates, Then they will buy these full-automatic full-height turnstile gates. Of course, In addition to the relatively expensive price, the full-automatic full-height turnstile gate also has better quality, longer service life, smoother operation, and the lowest noise.
