What is tyre killer?

Tyre killer is also called traffic spikes, which is a kind of tire-breaking road blocker driven by a hydraulic power device, remote control, or wire control. The tyre killer is composed of a high-strength blocking section and an auxiliary hard stab. It is mainly used to intercept vehicles with malicious collisions. The front collision of the high-strength blocking section blocks the entry of vehicles, and the auxiliary hard stab pierces into the tire. The air in the tire is released quickly, and the vehicle cannot move forward.

When the vehicle rushes through the roadblock machine at a high speed, the impact force of the vehicle will deform and damage the front of the vehicle, and the pressure of the wheel will make the stainless steel stab on the roadblock penetrate along the moving direction of the wheel, so as to effectively intercept illegal vehicles.

The stab of the tyre killer is relatively sharp. After the vehicle tire is rolled, it will be pierced in 0.5 seconds, and the gas in the tire will be vented through the vent hole, so that the vehicle cannot move forward. Therefore, it is a necessary anti-terrorism road blocker in some key security places.

The hydraulic tyre killer is normally closed during operation, that is, it is raised during security operations to prevent any vehicle from passing. When the releasable vehicle wants to pass, the spike can be dropped through the manual control of the security personnel, and the vehicle can pass safely.

The tyre killer can be lifted and lowered by remote control and a wire control switch. At the same time, it can also be linked with the HD camera set in front of the inspection station, receive the early warning signal, and the tyre killer will automatically rise to block suspicious vehicles. In addition, hydraulic traffic spikes can also be linked with multiple systems such as unique underbody scanning and speed detection.

Precautions for use of tyre killer:

1. Because the nail of the hydraulic tyre killer is extremely sharp, it is necessary to protect it during operation and maintenance, and pay attention to avoid injury.

2. When arranging the nail belt, a specially assigned person must be on duty nearby to prevent accidental injury to pedestrians and passing vehicles.

3. During the defense interception, no person is allowed to appear within 25m of the inertia direction of the intercepted vehicle and the nail belt, so as to avoid the injury to the surrounding personnel due to the loss of control after the tire is broken.

4. When the equipment is idle for a long time, it needs to be charged every 60 days or so.

5. Turn off the power switch in time after use.

6. It is strictly prohibited to maliciously fall it again, so as to avoid serious impact and damage to the equipment box.

7. The equipment belongs to mechanical and electrical products. Attention should be paid to waterproof, moisture-proof, and sun exposure during use and storage.

8. If the nail needs to be repositioned, the O-shaped rubber ring must be sleeved to the top seat of the nail shaft (nail base) first, otherwise, it is easy to cause the nail to fall off.

Composition of tyre killer:

The buried tyre killer is mainly composed of three parts: main frame of tire killer, hydraulic transmission station, and electric control part:

1. Mainframe:

The tyre killer is mainly composed of a turning body, a lifting body, and a base (anti-collision tooth nails can be added according to the needs of customers). The whole machine is of steel structure, welded with 16mm national standard A3 die steel plate and international standard channel steel, with high load-bearing and collision resistance; There are no electrical appliances and lines in the body, which is waterproof and safe. The device is buried in the lane or the designated position of the gate to restrict the passage of vehicles through the instructions of the personnel on duty.

2. Hydraulic transmission station:

The hydraulic transmission station of tire breaker is mainly composed of an oil tank, manual oil pump, complete set of hydraulic solenoid valve group, high-power motor, oil pump, oil cylinder, oil gauge, oil mark, external liquid level gauge, national standard high-pressure braided steel wire hydraulic oil pipe, etc. it is the power source of the whole set of roadblock system. The device is installed on one side of the roadblock machine, It is used together with the roadblock machine (the rising and falling speed can be changed through the regulating valve). In case of power failure, the baffle can be lowered or raised manually.

3. Electric control system:

Automatic electronic control part: control mainboard, auxiliary control board, leakage switch, contactless noise, high life contactor, precise starting time setting (to prevent the impact force generated after the oil cylinder stroke in place, which increases the service life of the oil cylinder), and automatic lifting can be set (adding ground induction coil to drive over the rod).

Automatic controller: including control box, remote controller, and manual button, which are controlled and used by the personnel on duty.

Types of tyre killer:

Tyre killers are divided into buried type tyre killer and deceleration belt type tyre killer.

Buried tyre killer means that the tyre killer is installed flat on the ground to avoid vehicle bumping and has an invisible effect.

The deceleration belt type tyre killer protrudes from the ground after installation and can play the effect of the acceleration belt.

The deceleration belt tyre killer is fast and convenient to install and can be moved at will. It can pass through container vehicles of less than 40 tons. The interception length can be customized, and the control distance is ≤ 100 meters. It can be used in conjunction with the parking barrier gate, connected with traffic lights, and controlled in multiple ways to intercept criminals to the greatest extent.

How tyre killer works:

Maybe someone will ask like this, how do traffic spikes work? Let’s explain it in detail.

The deceleration belt type tyre killer integrates the functions of the speed reducing belt and the tyre killer. The shape adopts the speed-reducing ridge shell. The shell is made of A3 high-quality steel as a whole.

A stiffener is set in the shell at an interval of 10cm, and a transmission shaft is set transversely. One end of the transmission shaft is located outside the shell and connected with the power drive device. The transmission shaft is provided with a groove and tire puncture The upper part of the shell is provided with a horizontal shell wall, which is provided with a tire breaking groove. The power driving device includes a motor and a trigger device, which are installed in the electric control box at one end. When in use, the trigger motor drives the shaft to rotate to make the tire breaking stab stand up (about 75 degrees from the ground).

The trigger device is installed at a position convenient for operation, and remote control can also be used for remote control, The deceleration belt tyre killer can not only control the vehicle speed, but also prevent illegal entry. It is a new type of security product to ensure the personal safety of road managers and the safety of the national property.

The deceleration belt tyre killer integrates the functions of the deceleration belt and tire breaker. It can not only control the vehicle speed, but also prevent illegal entry. It is a new security product to ensure the personal safety of road managers and the safety of the national property. According to the performance characteristics of the product and the actual situation of transportation, we must not only ensure the function of blocking and deceleration, but also be able to bear the heavy pressure of super tonnage vehicles for a long time.

Characteristics of tyre killer:

The feature of the concealed tyre killer is to set a protective device on the sharp nail tip. When people, animals, and bicycles step on the protective device by mistake, the device will not work. However, when the tire pressure of the car is out of date, because the load greatly exceeds the weight of people, animals, and bicycles, the device acts, the nail tip exposes the protective device and pierces the tire, so that the car can not drive.

The shape of the tyre killer is similar to the tank track, and the front is covered with spikes. A tyre killer is covered with about 118 spikes. After the tire is punctured, it can’t drive for about 3 minutes. Therefore, traffic spikes are a compulsory means for people who rush or drink driving to affect traffic. Today, we will introduce the product features of remote control traffic spikes.

1. The structure is firm and durable, the bearing load is large, the action is stable and the noise is low.  

2. PLC control is adopted, and the operation performance of the system is stable and reliable, which is convenient for integration.  

3. The traffic spikes can be controlled in linkage with other equipment such as parking barrier gates, or can be combined with other control equipment to realize automatic control.  

4. In case of power failure or failure, if traffic spikes is in the raised state and needs to be lowered, the raised roadblock cover can be lowered to the horizontal position through manual operation to allow vehicles to pass.  

5. The international leading low-pressure hydraulic drive technology is adopted, and the whole system has high safety, reliability, and stability.  

6. Remote control device: by means of wireless remote control, it can move the lifting of remote control barricade within about 30 meters around the controller (depending on the on-site radio communication environment).

7. The following functions can be added according to the needs of users: A: paper flow control: a paper flow device can be added to automatically control the rise and fall of tire belt by changing the card. Barricade: equipped with door (car stopper) / access control, which can connect the entrance gate, access control, and barricade.

Operation status of tyre killer:

Generally, the hydraulic tyre killer is normally closed during operation, but if it is raised during security operations, it can prevent the passage of any vehicle. If you want the vehicle to pass, the security personnel only need to manually put down the stab, so that the vehicle can pass.   

Of course, this is only a case. In case of emergency, the remote control can also be used, but if the signal is disturbed, the remote control will fail. Another case is to use wire control, that is, the control box. However, if the control box is damaged, the hydraulic tyre killer can no longer be used. Therefore, it can be used flexibly in a variety of ways. Generally, the control box can be placed in the security room and operated under normal conditions; The remote controller can be taken with you and can be used in case of emergency;

The control box can be used for remote monitoring and operation. Other methods include the concealed type and pedal type, which can also be used for emergency operations. There is also a case of manual pressure relief, which is used when the power is cut off, or power is cut off, power failure, etc. at this time, manual pressure relief can be used.

Generally speaking, the tyre killer will use a variety of control methods. Many factors are mainly considered. If only electronic control is used, how to implement blocking in case of a power failure? Or just use wire control (manual), then its blocking time will be greatly reduced. If there is only one control mode, the control end will become a weakness for terrorists to destroy the defense line. For example, by only using the remote control, terrorists can make the remote control fail with Signal Jammer; If only wire control (control box) is used, once the control box is damaged, the traffic spike becomes a decoration.

The control box is placed on the desktop of the security room for routine control; The control box is located in the central control room for remote monitoring and operation; Carry the remote controller with you for emergency operation; In addition, there are pedal type, concealed type, etc., which can be used as an alternative in a very emergency.

Finally, it is essential to cut off the power operation mode. Once the terrorists cut off or destroy the circuit, or temporarily cut off the power, there should be a standby power supply to ensure the normal operation of the device. There should also be a manual pressure relief device. If there is a power failure when it is in the raised state and a car needs to be released, the manual pressure relief device should be used.

Technical requirements for tyre killer:

The tyre killer is formed and bent by a complete steel plate without welding. If the hydraulic tyre killer wants to puncture in 0.5 seconds, it is more strict for material and workmanship requirements.

Because the traffic spike protects places with a first-class security level, and its prevention level is the highest, the technical requirements for prevention are also relatively high:

First of all, the hardness and sharpness of the stab should meet the standard. The broken tire spike of the tyre killer should not only bear the pressure of the vehicle, but also bear the impact of the vehicle moving forward, so it is a great challenge to the hardness and toughness of the road spike. The one-piece fine steel casting stab will have stronger hardness than the steel stab cut and polished with steel plate, and the hardness also determines the sharpness. Only road spikes with hardness up to standard can have good sharpness when they have a sharp shape. The one-piece fine steel casting spike fully meets such conditions.

Secondly, the hydraulic power unit should be placed underground (anti-collision damage, waterproof, and anti-corrosion). The hydraulic power unit is the heart of the road stabbing barrier. It must be installed in a hidden place (buried) to increase the difficulty of terrorist destruction and prolong the time of destruction. Buried underground, it puts forward higher requirements for the waterproof and anti-corrosion of the device. It is recommended to adopt an integrated sealed oil pump and oil cylinder for traffic spike barricade, with a waterproof grade of IP68, which can work normally underwater for a long time; The whole frame is recommended to be hot-dip galvanized to ensure anti-corrosion for more than 10 years.

Thirdly, multiple control modes should be used at the same time. If there is only one control mode, the control end will become a weakness for terrorists to destroy the defense line. For example, by only using the remote control, terrorists can make the remote control fail with Signal Jammer; If only wire control (control box) is used, once the control box is damaged, the spike roadblock becomes a decoration.

Therefore, it is better to have multiple control modes coexist: the control box is placed on the desktop of the security room for routine control; The control box is located in the central control room for remote monitoring and operation; Carry the remote controller with you for emergency operation; In addition, there are pedal type, concealed type, etc., which can be used as an alternative in a very emergency.

Finally, it is essential to cut off the power operation mode. Once the terrorists cut off or destroy the circuit, or temporarily cut off the power, there should be a standby power supply to ensure the normal operation of the device. There should also be a manual pressure relief device. If there is a power failure when it is in the raised state and a car needs to be released, the manual pressure relief device should be used.

Application site of tyre killer:

1. It is mainly used for vehicle access control in special places such as customs, border inspection, logistics, ports and docks, prisons, Treasuries, nuclear power plants, military bases, key government departments, airports, and so on; The purpose of effectively preventing vehicles from forcibly punching the card is to effectively ensure the traffic order, that is, the safety of main facilities and places, through the restriction of passing vehicles.

2. Entrance gates of state organs, military, and other important units: install lifting anti-riot roadblocks, which can control the lifting by electric, remote control, or card swiping, so as to effectively prevent the entry of vehicles from other units and the intrusion of illegal vehicles.

Why use a tyre killer?

With the development of science and technology, the progress of society, the popularity of cars, and the frequent occurrence of high-speed chasing on roads, some are caused by an illegal hit and run, and some criminals will try to get rid of the pursuit of the police by driving vehicles at high speed. No matter what kind of situation, it will bring no small potential safety hazards to road safety and personal safety.

Whether the use of tyre killer will become a common phenomenon in society, the figure of tyre killer in the road is very common. In order to protect the passing vehicles and pedestrians, hydraulic traffic spikes will be used and placed at the entrances and exits of buildings or roads. In the past, when police officers checked and controlled vehicles, they needed to intercept vehicles through old-fashioned mobile horses or plastic cones. It requires multiple policemen to work together, which is inefficient. In addition, when a criminal vehicle forcibly flushes the card, it cannot be intercepted quickly and effectively.

The application of tyre killer greatly reduces the road safety risk coefficient and effectively supports the interception tasks of military and police forces and various checkpoints.

The deceleration belt traffic spikes is a new electromechanical integrated access control product developed for the military and police forces, prisons, highway checkpoints, and other units to prevent vehicles from breaking through checkpoints. Its main structure is composed of anti-skid checkered plates, which can be flexibly assembled according to the user’s use scene. It has two functions of deceleration and tire pricking. It is a special anti-terrorism and anti-riot facility to control vehicle deceleration, prevent vehicles from entering the card savagely, and ensure the safety of duty personnel and national property.

Maintenance of tyre killer:

Tyre killer can be seen everywhere in our life, which can not only ensure our safety, but also bring some enterprise development convenience to our life. How to maintain the tyre killer? Let me show you:

1.  Clean the surface of the tyre killer every day to keep the surface clean and free of dust. This is also to prevent dust from entering the interior of the device.

2. Secondly, the equipment needs to be checked every day to test the software and hardware equipment that block the work, and see whether the indications of various devices are correct.

3. Then, if the equipment management of tire breaker fails, the enterprise must cut off the power first, and then check and analyze the problem.

4. If the equipment is not used for a long time, the waterproof and moisture-proof work must be completed in place, so as to avoid exposure to wet environment as much as possible; And it should be lubricated regularly to prevent parts and equipment from rusting.
