Hengyang Heavy Industry DSZ series coal mine brakes are noise free and easy to maintain

Product features: The steel wire rope catching device is installed on the traction steel wire rope. When the traction steel wire rope exceeds the speed limit, it directly brakes the traction steel wire rope to avoid flying accidents and ensure the safety of equipment and personnel; This device has a simple structure, reliable performance, safety and effectiveness, and convenient operation.

Working method: The steel wire rope catching device is installed above the traction steel wire rope at the entrance and exit of the driving wheel of the mining cableway. The traction steel wire rope is sandwiched between the movable wedges of the traction steel wire rope braking device. When the mining cableway operates normally, the movable wedges do not move. When the speed detector detects that the traction steel wire rope is running over speed, the thruster acts. The front end of the push rod is equipped with a connecting rod to push the movable wedges, Due to the dovetail groove connection between the inner side of the movable wedge and the outer side of the wedge track, the movable wedge slides towards the traction steel wire rope along the inclined surface of the wedge track. When the friction block on the movable wedge contacts the traction steel wire rope, due to the movement of the traction steel wire rope, the movable wedge is pulled towards the direction of the traction steel wire rope, increasing the pressure of the movable wedge on the traction steel wire rope and exerting a braking effect on the traction steel wire rope, The function of the wedge track is to prevent the movable wedge from instantly locking the traction steel wire rope, ensuring braking safety.
