Pneumatic sleeper gate is an indispensable safety protection device in coal mine rail transportation. The pneumatic sleeper gate uses gaseous power to achieve the closure of the sleeper gate, relying on the spring force sleeper gate to automatically open. The pneumatic sleeper brake is always in a state of opening and blocking the mine car in one direction, blocking the mine car in this direction and preventing the mine car from slipping. When the mine car in this direction needs to pass through the sleeper gate, it uses pneumatic operation to close the sleeper gate to release the mine car. After the mine car passes through, the pneumatic sleeper gate automatically opens. Run the mine car in the opposite direction without operation through the pneumatic sleeper gate, and automatically open after passing.

Before installation, all parts and components shall be thoroughly inspected for defects during transportation and storage, and no defective parts shall be used. Connect the pneu matic brake to the rail through the I-steel, adjust and tighten it, the cylinder is fixed to the I-steel through the installation plate, the front and rear axles of the cylinder are conn ected, and the air control box is fixed in the designated position. Connect the high-pressure intake pipe and the cylinder intake pipe, Install cylinder shield after debugging.

Debugging rotating gas control valve, trial operation of the cylinder, so that the sleeper brake shut down smoothly, lift the air control valve, the sleeper brake automatically open ed, when not operating, the sleeper brake is always in the state of opening and blocking.
气动卧闸主要由卧闸、传动轴、摇杆、扭转弹簧、气缸、气控箱等零部件组成。气动卧闸依靠弹簧力使卧闸始终处于对一方向矿车开启阻车状态，阻挡一方向矿车， 防止矿车自溜，搬动气控箱的控制阀，气缸活塞杆在压缩空气的作用下伸出，同时带动传动机构的摇杆、传动轴进行转动，关闭卧闸，放行矿车，当矿车通过后， 搬下气控箱的控制阀，卧闸自动开启。对反方向运行矿车不用操作就可通过气动卧闸，通过后自动开启。
Pneumatic brake is mainly composed of sleeper brake, transmission shaft, rocker, torsion spring, cylinder, air control box and other parts. The pneumatic sleeper brake relies on the spring force to keep the sleeper brake in a state of opening and blocking the mine truck in one direction, blocking the mine truck in one direction, preventing the mine truck from slipping away and moving the control valve of the gas control box. The cylinder piston rod is under the action of compressed air. Out, At the same time, drive the joystick and transmission shaft of the transmission mechanism to rotate, close the sleeper gate, release the mine truck, and when the mine truck passes through, move the control valve of the gas control box, and the sleeper brake automatically opens. Run the mine car in the opposite direction without operation through the pneumatic sleeper gate, and automa tically open after passing.
