ZBQ-127 Rail type Resistor Bidirectional Mining Resistor
The blocking wheel type blocking device used in mining hydraulic blocking devices has a pair of blocking claws and spring buffering devices. When the wheel hits the blocking claws, the blocking claws compress the spring fitted on the rear of the fixed shaft, and the energy of the impact is absorbed by the spring. The tail of the blocking claw is connected by a connecting rod and a control mechanism. The reciprocating motion of the hydraulic cylinder piston rod causes both blocking claws to open or close simultaneously. When closed, it blocks the car, and when opened, the mining car can pass through. Obstacles can be divided into front and rear types according to their circuit settings. The front derailleur is used for limiting the position of the mining car, while the rear derailleur is used for limiting the train and is mechanically linked with the shunting claw device. Only when the rear derailleur is opened, the pulling claw will be lifted to move the mining car. When the rear derailleur is closed, the pulling claw will not be lifted, and the trolley can smoothly pass under the mining car.
