What problems should be paid attention to in the use of mine winch?
Mine winch It is a winch used for dispatching vehicles. It is often used in underground mining area, coal bunker, loading station control room, hauling car and other auxiliary traction operation.
Precautions when using mine winch:
The drum is not allowed to gather and start to prevent the impact load from damaging the parts. When there is often counter torque on the drum of mine winch, the two brakes brake at the same time to avoid burning the motor.
When the motor of mine winch rotates, it is strictly forbidden to brake two brakes at the same time to avoid burning out the motor. The temperature of winch brake band shall not exceed 70 ℃. If the temperature continues to rise, stop and check. Always pay attention to check whether the end of the rope is firmly connected to prevent sports car accidents. The winch must not be overloaded. When lowering heavy objects, the mining winch must turn on the motor. Pulley is not allowed!
With the progress of coal mining technology, this kind of mining pillar winch equipment has been used by more and more mechanized coal mining enterprises as installation, recovery and traction of various equipment and spare parts.
Because of its low height and light weight, it is especially suitable for mining face of thin coal seam and steep coal seam, as well as all kinds of mining face to recover metal column sunk into floor or buried by gangue pressure. It is the equipment of coal mining face back pillar caving. In addition to the front and rear coal pillar work, it can also be used to transport stronger vehicles, bringing a lot of convenience to everyone.
In what environment can mine winch be used?
The mine winch should be at the ambient temperature of - 10 ℃ ~ + 40 ℃; the relative ambient temperature should not exceed 95% (+ 25 ℃) and the height should not exceed 1000m. For the height above 1000m, the cooling effect of air and the reduction of dielectric strength should be considered. The selected electrical equipment should be designed or used according to the agreement between the manufacturer and the user.
