Can bollards be used with the lock system?
The 『automatic bollard』belongs to the equipment for controlling vehicle traffic, which can be used in combination with the gate control system, or used alone.
『Bollards』 are widely used in many occasions, such as urban traffic, the gate and surrounding of military and national important organs, pedestrian street, highway toll station, airport, school, parking lot, etc.
Through the restriction of passing vehicles, the traffic order and the safety of main facilities and places are effectively guaranteed.
『Bollards』 are divided into three types: automatic lifting type, semi-automatic lifting type and fixed type; automatic lifting type is divided into hydraulic lifting type and automatic lifting type.
It is specially designed and developed to prevent vehicles from breaking into sensitive areas. The automatic bollard has high practicability, reliability and safety.
It is composed of bottom base, lifting and blocking barrier post, power transmission device, control and other parts. According to the different needs of different customers, it has a variety of configuration modes for users to choose and can meet the functional requirements of various customers.
The hydraulic oil forms a certain pressure by the vane pump, and enters the lower end of the hydraulic cylinder through the oil filter, explosion-proof electromagnetic reversing valve, throttle valve, hydraulic control check valve and balance valve, so as to make the piston of the hydraulic cylinder move upward and lift the heavy objects. The return oil at the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic reversing valve, and its rated pressure is adjusted through the overflow valve, and the reading value of the pressure gauge is observed through the pressure gauge.
In order to make the brake safe and reliable and prevent accidents, a hydraulic control check valve, i.e. a hydraulic lock, is added to ensure the safety of self-locking when the hydraulic pipeline bursts accidentally.
When it comes to safety applications, different bollards are used to block different objects. The automatic bollard is equipped with overload sound control alarm to distinguish overload or equipment failure.
The electronic control system can control the rotation of the motor through the explosion-proof button, so as to change the direction of the explosion-proof electromagnetic reversing valve, so as to keep the load up or down, and through the; logo; program to adjust the time delay, so as to avoid the inflexible rise and fall caused by the frequent start of the motor and the phenomenon of jamming.
