[0002] Coal mining machine is the main mechanical equipment in coal mining production, mainly responsible for coal mining. It is one of the main equipment of comprehensive mechanized coal mining process and plays an important role in coal mining production. Its operating status directly affects the production efficiency and safety of coal mines. In the longwall coal mining face, the coal mining machine uses the working mechanism to break the coal from the coal body (breaking coal) and load it into the working face conveyor (loading coal). The maintenance equipment used for fault detection is mainly used to detect coal mining machine faults and perform maintenance.

[0003] In the actual operation process, coal mining machines will inevitably have various faults, such as motor failure, transmission system failure, hydraulic system failure, etc. If these faults are not discovered and handled in time, they will not only cause the coal mining machine to stop, affecting production progress, but may also cause safety accidents. At present, the fault detection of coal mining machines in coal mines mainly relies on manual inspections and regular maintenance. This method has problems such as long detection cycle, low efficiency, and high missed detection rate. For this reason, we propose a maintenance equipment for coal mining machine fault detection in coal mines to solve the above problems. Utility Model Content
