　　The 900-30 pneumatic rail type car blocking device is a commonly used coal mine car blocking equipment, which can be installed at the slope change point or inclined shaft entrance of the inclined roadway to prevent accidents caused by car racing at the wellhead. It can also be installed at the shaft entrance, operation system, gangue discharge system, etc., as a car blocking device for the car yard. According to the different power sources used, the rail holding type car resistor is divided into three types: electro-hydraulic, pneumatic, and manual.

　　1、 Control mode of 900-30 pneumatic rail holding type obstruction:

　　The 900-30 pneumatic rail holding type car stopper can be matched with the inclined lane sports car protection device to achieve synchronous control with the lifting winch, that is, when no mining car passes through the stopper, the stopper is in a normally closed blocking state. When the mining car is running normally and approaching the rail type blocking device, the blocking device opens and the mining car passes through. After the mining car passes through, it automatically closes. If abnormal passing occurs. For example, if the car slips due to an error in removing the hook at the wellhead, the blocking car will not open, but will remain in a blocking state, and the mining car will be blocked.

　　2、 Parameters of 900-30 pneumatic rail holding type car stopper:

　　Track gauge: 900mm

　　Gas source pressure range: 0.28-0.8mpa

　　Using mining truck tonnage: 1 ton/1.5 tons/3 tons

　　Allowable deformation: 5600/7800

　　Weight: 405kg

　　3、 Product composition of 900-30 pneumatic rail type obstruction:

　　It consists of three parts: the electric control device of the car blocking device, the air filtration combination, and the main body of the rail holding car blocking device. The model of the electric control device for the car blocker is ZZC127, which consists of a mining explosion-proof and intrinsically safe electric control box, a position sensor, and three parts. The electric control device for the car blocker has the MA mark.

　　4、 Working principle of 900-30 pneumatic rail holding type car stopper

　　The 900-30 pneumatic rail holding type car blocking device is designed on the outer side of the track. The working principle is to pull the control valve of the pneumatic control box, and the cylinder pushes the blocking wheel block to open. When the mining car passes through, the control valve of the pneumatic control box is pulled in the opposite direction, and the cylinder pushes the blocking wheel block to close, thereby achieving blocking and stopping of the mining car.
