Working principle of fixed car stopper:
Fixed car stopper, the main frame is directly fixed on the track, because there is no damper, so it can not slide, mainly relying on hydraulic buffer device to absorb the kinetic energy of escaped vehicles. The working principle of fixed car stopper is the same as that of hydraulic buffer device in CDH-Y hydraulic buffer sliding car stopper.
The fixed car stopper adopts integral steel plate welding structure. Reasonable stress, good stability and strong impact resistance. The braking force level increases in turn. According to the structural strength of the user's vehicle, different braking force levels are designed to meet the requirements of different vehicle speeds and taxi distances. There are spring pieces in the damper, which can better prevent the car stopper from blocking the rail or the braking force from dropping sharply. The elastic force of the middle coal spring plate is pressurized by the pressure bolt, which has good self-locking performance, simple method and easy control and inspection. Adjust the opening pressure of the pressure valve according to the different requirements of the vehicle to ensure that the resistance of the buffer cylinder matches the friction resistance of the main body of the car stopper, so as to obtain a good buffer effect. The length of the oil cylinder ali 1 1 can be changed to obtain different buffering effects. After the fixed car stopper is hit, it can automatically return to its original position. Its oil storage tank is installed on the upper part of the oil cylinder and the pressure valve. When the oil cylinder is reset, it can automatically replenish hydraulic oil to the oil cylinder through the one-way valve.
