Advantages of hydraulic road blockers:

Hydraulic rollover road blocker machine is just like a wall to prevent the passage of illegal vehicles on the road. Its protective performance includes a single-sided anti-collision road blocker machine and a double-sided anti-collision road blocker machine. Generally, a single-sided road blocker is the most widely used in the market. Road blocker machines on the market generally use hydraulic power to realize the lifting function of the turning body. Its advantages are as follow:

1. The reaction speed of the hydraulic turnover road blocker machine is relatively fast, and the lifting time can be up to 3 seconds, which is extremely valuable. Because it adopts the hydraulic driving unit, the action is soft and calm, which well solves the problem of large working noise of the traditional pneumatic lifting due to the air pump.

2. The safety factor of the hydraulic road blocker machine is higher. Compared with other road blocker devices, the road blocker machine can achieve mandatory interception through its own driving technology, and its load-bearing or anti-collision ability is very strong. It is also flexible and simple to operate, and the action is very fast.

3. The hydraulic road blocker machine has the characteristics of low maintenance cost and low failure rate.

Working principle of road blocker:

The road blocker machine takes hydraulic energy as the power to realize the lifting function of the turnover body. The working principle of road blocker machine is:

1. Mainframe of road blocker machine:

The mainframe of the road blocker machine is composed of a frame, movable flap, hydraulic cylinder, and two groups of balance mechanisms. The movable flap is connected with the frame through two groups of rotating shafts. The upper and lower earrings of the hydraulic cylinder are respectively connected between the frame and the movable flap through the rotating shaft, which is the power source for the movement of the mainframe. The two groups of balance mechanisms are connected between the movable flap and the frame, which plays the role of load balance and buffering.

2. Hydraulic system:

The hydraulic system consists of a drive motor, hydraulic oil pump, combined solenoid valve, manual control valve, pressure indicator, etc.

3. Interface function description:

Hydraulic system of road blocker:

Hydraulic road blocker machine plays a very important role in road traffic and can be used in many special occasions. It can effectively prevent vehicles from forcibly reloading checkpoints. So what are the components of the road blocker system?

1. Mainframe: the mainframe of the road blocker machine is composed of a hydraulic oil cylinder, movable flap, and frame, which can play the role of load balance and buffer. The whole machine is made of steel structure, welded with steel plate and channel steel, with a strong anti-collision ability and load-bearing ability. There are no electrical appliances and lines in the mainframe, which can achieve the waterproof effect and safe use.

2. Hydraulic transmission station. The hydraulic transmission station mainly changes the rising and falling speed by oil tank and manual oil pump valve). In case of power failure, the baffle can be lowered manually or raised manually.

3. Electric control system: automatic electronic control part, control motherboard, and automatic controller: including control box, remote controller, and manual button, which are controlled and used by the personnel on duty.

The above content introduces the components of the hydraulic road blocker system, which fully reflects its role.

Advantages of hydraulic system

1. The hydraulic power system of the road blocker machine is very quiet for mechanical products. This is very difficult for many machines. Due to the noise attenuation system, the decibel can be controlled within 60 dB.

2. The impact on the environment is very small, which meets the growing demand for low environmental impact and creates a new low point for the impact on the environment.

3. Low energy consumption and low power voltage cost to compensate for the vacancy of variable flow pump configuration and ensure the low cost of mechanical operation. Combined with a high-efficiency motor, the power cost is absolutely kept at a low level.

The power unit is also part of the hydraulic system and helps the hydraulic system supply fuel correctly. The power unit controls various valve switches in the system to realize rapid system switching. By using this product, we can timely understand the oil supply status in the system, find out the faults in the system, realize the rapid shutdown of the system and avoid major accidents. The application of power units in the hydraulic system is very mature, which is helpful to solve the problem of oil supply.

Precautions for road blocker maintenance:

There are some details you need to know in the process of maintaining the hydraulic road blocker. What do these details mainly include? I’ll take you to know more about this problem.

1. In the process of electrical maintenance, the relevant power supply shall be cut off in time, and signs such as maintenance and overhaul shall be hung on obvious positions.

2. Check the working condition of switches, buttons, indicator lights, and buzzers once a month.

3. When there are vehicles or pedestrians above the turnover barrier machine, lift it strictly to avoid harm.

4. Keep the drainage at the bottom of the turnover barrier body unblocked and the surrounding clean to ensure the service life, performance, and waterproof tightness of the lifting barrier machine parts.

5. During the operation of anti-terrorism road blockers, prevent continuous rise and landing. Rising and falling are not suitable for continuous fast switching, which is easy to shorten the service life of the motor and hydraulic pumps.

6. On large ice and snow days, if there is serious ice inside the pile body of the roadblock machine, stop lifting and use it after freezing by heating and other methods.

7. Regularly check the oil level in the oil tank of the anti-collision road blocker. If the oil level is lower than the bottom line, add oil; If the oil becomes dark and turbid, you need to consider changing the oil.

Whether the road blocker is worn?

Next, let’s introduce the method to judge whether the anti-collision road blocker is worn.

Road blocker is a traffic security facility with good characteristics, such as anti-collision, anti-terrorism, anti-rust, corrosion resistance, long service life, etc. it is widely used in government units, nuclear power plants, and other places. The anti-collision roadblock machine can be used together with automatic rising bollards and parking barrier gates or used alone. It is mainly composed of a mainframe, hydraulic transmission station, and electric control system. However, when using the anti-collision road blocker machine in life, there may be different degrees of wear. If the hydraulic anti-terrorism road blocker machine has the function of machinery, it will collide, and the collision will inevitably wear. How many manifestations of the wear of the anti-collision road blocker machine? Let’s take a look:

1. There are three periods of wear of the anti-collision road blocker machine. The running-in period: due to the rough surface of the conflicting pair and the slight error during installation, the flatness of the conflicting pair is poor, the normal load is large and the wear is fast, which also depends on the situation of the conflicting pair itself.

2. During the normal wear period, if the collision pair cooperates normally, wears normally, and has the minimum wear and collision, the operation time of the anti-collision road blocker machine will be long. If the wear reaches a certain degree, it will enter the limit wear period, and the wear will increase at this time.

3. If the anti-collision road blocker machine has the function of machinery, there will be a collision. If there is a collision, there will be wear. There is a rule of wear: that is, the volume wear is directly proportional to the relative sliding interval of the collision pair; The yield strength proportional to the normal load is inversely proportional to the hardness.

On the basis of theory, it is proved by experiments that the correlation between wear rate and impact element is very small. Generally, there is a level difference between impact elements, and there will be three levels of difference in wear rate. Therefore, the change of impact coefficient is not fixed.
