Description

Technical Field

[0001] The utility model relates to the technical field of automatic hook-removing devices, in particular to an automatic hook-removing device for a train flatbed car. Background Art

[0002] Before a car loaded with goods in a heavy train enters the dumper room to perform dumping operations, the car needs to be separated from the entire train queue. At this time, a decoupling operation needs to be performed. The decoupling operation here refers to opening the hook tongue of the coupler of one of the two adjacent cars including the car loaded with goods, so an automatic decoupling device is required.

[0003] In addition, the ladles loaded in the carriages often exploded, and after the explosion, the molten iron at 1500 degrees Celsius splashed 30 meters away. The workers were easily injured when manually unhooking. The manual unhooking efficiency was low, and the rails were stuck to the molten iron and could not be used. Therefore, the automatic unhooking device can effectively protect the safety of the workers. Utility Model Content
