截至目前，昂际智航已与沃飞长空、追梦空天、览翌航空、御风未来、小鹏汇天等多家主机厂合作，为其提供航电及飞控解决方案The maintenance of mining hoisting winches mainly includes the following contents:

1. Regularly check the wear of the brake shoes, and adjust them in a timely manner when the gap reaches 2 millimeters to avoid affecting the braking torque; When the wear reaches 5 millimeters, new brake shoes should be replaced in a timely manner, and the contact area with the brake wheel should reach more than 60% before use.

2. Regularly inspect the safety protection device, as well as the contact condition of the reducer's tooth surface, whether there is corrosion, abrasion, adhesion, and other defects, as well as the sealing and lubricating oil situation. If problems are found, corresponding measures should be taken in a timely manner to resolve them, and the lubricating oil should be replaced once a year.

3. When inspecting or adjusting the hydraulic station, a safety electromagnet should be used to cut off the power. The magnet of the hydraulic valve should not be disassembled under normal circumstances, otherwise it will affect the magnetic force and performance. Each homework team needs to check whether the action of the safety brake solenoid valve is reliable.

4. Add lubricating oil to the winch in a timely manner according to regulations. If the winch is left unused for a long time, it should be stored in a dry place to prevent electrical moisture. The exposed parts of the winch should be coated with protective oil, and each friction part should be coated with lubricating oil.

5. The disassembly sequence of the winch is opposite to assembly. The winch should be disassembled into components first, and then each component should be disassembled. When disassembling, the upper body of the sealing cover should be removed first, and the connecting bolts between the drum part, motor component, and base should be loosened, and these two parts should be removed. When disassembling each part of the winch, attention should be paid to the number and thickness of adjusting shims in each part, so that when reassembling components, the original assembly accuracy of the winch can be maintained and cannot be arbitrarily increased or decreased.

During the dismantling process of the winch, it is strictly prohibited to use a hammer to hit or smash it hard. Be careful and do not damage the parts or damage their surfaces.

7. The winch should be scheduled for minor, medium, and major repairs according to the actual situation.

The above information is for reference only. It is recommended to consult professional maintenance personnel and carry out maintenance according to specific situations.
