Pneumatic car arrester is an indispensable safety protection in the process of coal mine rail transportation Device, pneumatic car arrester is used in coal mine transportation routes to control the positioning and stopping of mine cars, prevent the mine cars from sliding away, separate cars and remove hooks, etc. The pneumatic car arrester is wheel-blocking type and rail-holding type. The pneumatic car arrester uses gas power to open and close the wheel block, which can easily block and stop the mine car, thus providing an effective guarantee for the safety of coal mine rail transportation. Pneumatic car arresters are mainly controlled by pneumatic control boxes. Pneumatic car arresters are mainly used for mine car transportation and track transportation. Pneumatic car arresters have been widely used in coal mining enterprises across the country.
: >Structure of pneumatic car arrester
Pneumatic car arrester is mainly composed of car arrester, arm, transmission shaft, rocker, cylinder and air control box.
: >The working principle of the pneumatic car arrester
The pneumatic car arrester is a wheel-blocking mine car blocking device. The car rental claw of the pneumatic car arrester is designed on the outside of the track. The working principle is as follows When the control valve of the pneumatic control box is turned, the cylinder piston rod extends under the action of compressed air, and at the same time drives the rocker, transmission shaft, and arm of the transmission mechanism to rotate, thereby opening the pneumatic blocking claw. When the mine car passes, the control valve of the pneumatic control box is pulled in the opposite direction, the cylinder piston rod contracts, and at the same time drives the components of the transmission mechanism to rotate in the reverse direction, and the blocking claw is closed, thereby blocking the mine car and stopping it.
