Description

Technical Field

[0001] The utility model relates to the technical field of mine mining, in particular to an automatic unhooking device for an inclined shaft loading yard. Background Art

[0002] Inclined shaft rail hoisting systems are widely used for hoisting and transporting slag in deep development and extension projects in metal and non-metal mines. In traditional inclined shaft hoisting operations, the mine car hoisted from the bottom of the inclined shaft must be manually unhooked. Once the hoisted mine car reaches the unhooking area, the winch operator must control the car's speed to facilitate unhooking. This requires close coordination between the winch operator and the unhooker. A single error by either operator could result in unhooking failure or the mine car injuring the unhooker. This traditional operation not only poses significant safety risks, but also inefficiencies and wastes human resources. Utility Model Content
