13. 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:

14. 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.

15. 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.
Working principle of road blocker:

16. 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:
Ascending and descending input: command control input interface for the
ascending and descending of roadblock machine; The precise time of
raising limit and lowering the limit is adjustable: through the limit time, the
service life of the roadblock machine is prevented from being affected by
the long-term operation of the roadblock machine in the blocked state;
Ascending solenoid valve and descending solenoid valve: switch and close
the oil circuit solenoid valve of the hydraulic pump of the roadblock
machine, so as to realize the functions of ascending, descending and
stopping the operation of the roadblock machine; Raise and lower
regulating valves to regulate the rising and falling speed.

17. 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.

18. 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.

19. 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.

20. 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.

21. 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:
Whether the road blocker is worn?

22. 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.
