With the great support of the coal industry, people often use a lot of mechanical equipment in coal mine work. These mechanical equipment, such as JK mine hoist, can not only help people transport or dig coal more easily. And it's very efficient.

JK mine hoisting mechanism moving disk and reel are connected by separate assembly structure. The matching surface of brake disc and reel has been completed in the manufacturer, and the reel, brake disc, main bearing and bearing seat are respectively installed on the main shaft. Put the assembled spindle device on the combined lathe, and place two main sockets to handle the two sides of the fixed rope plate brake disc respectively.

When the explosion-proof main motor of JK mine hoist is started, the motor rotor transmits the power to the high-speed shaft of the reducer through the elastic coupling, and after the reducer decelerates, the passive shaft of the reducer will decelerate. It is driven by gear coupling. For spindle equipment. If the direction of the explosion-proof motor is constantly changing, the reel may become entangled or loose, causing the lifting container to move back and forth in the wellbore.

When installing the winch, it must be placed on the fixed base of the raft. During transportation, it should be very firm and stable, and the outer blade of raft root should be kept flat. When adding oil to the reducer and bearing box, proper amount of grease must be added to prevent the added oil from affecting the normal operation and operation of the heavy winch, and industrial gear oil should be used. For reducer. And friction is reduced.

Before operating JK mine hoist, please check that the handle and each control switch are in the correct position. Check whether the indication of various instruments on the console meets the requirements. The high and low pressure meters indicate whether they are within the allowable range, and the low pressure is 380V. High voltage between 5700-6300v.

 JK mine hoist

Check whether the hydraulic pressure of the hydraulic station and lubricating oil pump station meets the requirements. Whether the main shaft of disc brake reducer leaks oil and whether the oil passage is unblocked. Check whether roll, brake, emergency brake and depth indicator are sensitive and reliable.

Four reasons for insufficient classification pressure of winch

1. The oil pump is too hot.

Causes: 1. The oil pump is worn or damaged; 2. The viscosity of the oil is too low;

Disassembly method: 1. Repair or renew; 2. Use hydraulic oil with recommended viscosity.

2. The oil pump cannot turn right.

Cause: wiring error;

Method: correct the rotation direction of the oil pump.

3. The speed of oil pump is too low.

Cause: motor failure;

Troubleshooting: troubleshooting.
