Shaft Sinking Winch is a mining product that everyone knows! Xiaobian tells you that our Shaft Sinking Winch is equipped with a depth indicator, which is very important. Only in this way can we make full use of the advantages of mining winches and bring benefits to all.
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.
Place the three-ring wire rope as a friction ring on the drum to reduce the tension between the wire rope and the drum.
A spare wire rope for periodic testing or the like may be retained in the photosensitive drum or wound on the photosensitive drum.
The rim of the flywheel is higher than the wire rope in the rope groove, and the upper part should be greater than 1.5 times the diameter of the wire rope. For padded wheels, fasten them. When the pad wears to the depth of the wire rope, or if the diameter of the wire rope is half of the side, it should be replaced immediately.
When lifting materials in a mining winch, if the length of the inclined well is greater than 300 m, the speed of the lifting vessel 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) Set the overspeed protection device to stop the lifting brake and achieve safe braking when the lifting speed exceeds 15% of the specified speed;
(2) Shaft Sinking 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-rollover 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) Shaft Sinking Winch sets the short circuit and protection device of the main drive motor to ensure timely and safe braking;
(4) Set the overcurrent and non-electric protection device. When the hoist is overloaded or the power is interrupted, the hoist brake stops.
