Mining Scraper Winch is a well-protected product that protects miners' safety products and transports materials in the mine through the ropes of used winches. The protection measures for the winch are also very good.
The rope eye on the drum is not allowed to have sharp edges and burrs, nor can the elbow form an acute angle to prevent the rope from deforming. A three-ring wire rope is placed on the drum as a friction ring to reduce the tension between the wire rope and the drum. A spare wire rope for periodic testing or the like can be left in the photosensitive drum or wound on the photosensitive drum.
The rim of the flywheel needs to be higher than the wire rope in the rope groove, and the upper part should be 1.5 times larger than the diameter of the wire rope. For padded wheels, it is necessary to securely hold the mat. When the pad wears to the depth of the wire rope, or if the wire rope is half the diameter of the wire, it should be replaced immediately.
When lifting materials in the Mining Scraper Winch, if the length of the inclined well is greater than 300 m, the speed of the lift should be greater than 5 m / s. The electromechanical control system of the mining winch hoist shall have the following protective and electrical locking devices:
(1) The Mining Scraper Winch is equipped with an overspeed protection device. When the lifting speed exceeds 15% of the specified speed, stop lifting the brake to achieve safe braking;
(2) Mining Scraper Winch is equipped with anti-rollover protection on the derrick and depth indicator. When the lifting container or counterweight exceeds the normal unloading position (the car enters and exits the vehicle), the brake will stop and the brake will stop. Achieve safe braking. The anti-overturn protection device should also be equipped with an interlocking device, which can no longer be connected to the power source in the winding direction;
(3) Mining Scraper Winch is equipped with short-circuit protection for the main drive motor to ensure timely and safe braking;
(4) Set overcurrent and non-electrical protection devices. When the hoist is overloaded or the power is interrupted, the hoist brake will stop.
