Pneumatic horizontal gate is an essential safety protection device in coal mine rail transportation. The pneumatic horizontal gate uses gas power The horizontal gate can be closed and the horizontal gate can be opened automatically by spring force. The pneumatic horizontal gate is always open and blocking the mine car in one direction, blocking the mine car in this direction and preventing the mine car from sliding away. When the mine car in this direction needs to pass through the horizontal gate, use pneumatic operation to close the horizontal gate to release the mine car. When the mine car After the vehicle passes, the sleeping gate opens automatically. The mine car running in the opposite direction can pass through the pneumatic horizontal gate without any operation, and it will automatically open after passing through.
The pneumatic horizontal gate has the characteristics of simple structure, convenient installation and maintenance, labor-saving operation, safety and reliability. The pneumatic horizontal gate has been widely used in coal mining enterprises across the country.
: >Structure composition of pneumatic horizontal brake
Pneumatic horizontal brake is mainly composed of: horizontal brake, transmission shaft, rocker, torsion spring, cylinder, air control box and other components.
: >Working principle of pneumatic horizontal gate
The pneumatic horizontal gate relies on spring force to always open and block the mine car in one direction, blocking the mine car in one direction and preventing the mine car from slipping and moving. The control valve of the air control box and the cylinder piston rod extend under the action of compressed air. At the same time, they drive the smoke detector of the transmission mechanism and the transmission shaft to rotate, close the horizontal gate, and release the mine car. When the mine car passes, remove the air control The control valve of the box and the horizontal gate are automatically opened. The mine car running in the opposite direction can pass through the pneumatic horizontal lock without any operation, and it will open automatically after passing through
