The vehicle blocking device is an essential safety protection device in the process of rail transportation in coal mines. It is used in the transportation route of coal mines to control the positioning and stopping of the car, prevent the car from slipping away, separate the car and hook. The dynamic blocking device is a wheel blocking type. The device USES gas power to open and close the wheel blocking, which can conveniently stop the mining car, thus providing an effective guarantee for the safety of rail transport in coal mine. The product has been widely used in coal mining enterprises all over the country.
Pneumatic vehicle resistance, manual general (QZC), simple (QZCY), two-way resistance model (QZCS).
Feature of wheel stop
1. Wheel arrester has simple structure, low cost, easy installation and maintenance;
2. Pneumatic operation of wheel arrester is labor-saving, safe and reliable.
Wheel arrester work principle
Wheel blocker wheel blocker is designed on the outside of the track, the working principle is to pull the control valve of the air control box, the cylinder pushes the wheel blocker to open, when the car through, reverse pull the control valve of the air control box, the cylinder pushes the wheel blocker to close, so as to achieve the stop of the car.
