Fixing device for rotating car coupler

The invention relates to the technical field of car tipplers, and particularly discloses a fixing device for a rotating car coupler, which is arranged between a striker and a hook shoulder of the rotating car coupler. Comprising a striker clamping block assembly clamped with a striker, and a car coupler clamping plate assembly with one end clamped with the striker clamping block assembly and the other end clamped with a coupler shoulder. According to the invention, the rotation of the rotary coupler relative to the striker is effectively limited, and the temporary fixation of the rotary coupler is realized; the fixing device can ensure that one rotating coupler in the couplers connected with the fixing device is fixed, and ensures that the rotating coupler can be accurately reset together with the unloaded vehicle after the unloaded vehicle is reset. 本发明涉及翻车机技术领域，具体公开了一种转动车钩用固定装置，设置在冲击座与转动车钩的钩肩之间；包括与冲击座卡接的冲击座夹块组件、以及一端与冲击座夹块组件卡接且另外一端与钩肩卡接的车钩夹板组件。本发明有效的限制了转动车钩相对冲击座转动，实现了对于转动车钩的临时固定；能够保证与本固定装置相连车钩中的一个转动车钩被固定，确保卸
