[0002] In coal mining, the unloading of coal, gangue and domestic garbage is required, mainly to ensure the smooth operation of coal mine production, and to achieve effective utilization of resources and proper disposal of waste. Coal excavation is a necessary link in coal mining, and gangue is the waste generated during coal mining and treatment. Its unloading helps in subsequent utilization and treatment, avoiding waste of resources and environmental pollution. The unloading of domestic garbage is an important aspect of environmental management in coal mining areas and the guarantee of workers' lives, which helps to maintain the cleanliness and hygiene of mining areas.

[0003] The existing high-position tumbling cage uses an 11.4KW winch to pull the mine car on a 15m long slope, and uses a power-driven rotating device to unload it. Only one mine car can be unloaded at a time, which easily causes wire rope wear and wire breakage. The wire rope needs to be replaced frequently, which is time-consuming and labor-intensive. It is also prone to slipping, posing a major safety hazard, and has low work efficiency. Therefore, the utility model proposes a simple high-position tipping device to solve the problems existing in the prior art. Utility Model Content
