Abstract | The utility model belongs to the technical field of hydraulic support valves, particularly relates to a limiting device for an operating handle of a coal mine hydraulic support valve group, and aims to solve the problem that potential safety hazards exist when a worker mistakenly touches the operating handle of a hydraulic support in the prior art. A first limiting mechanism is arranged on the outer wall of the top of the bottom plate, and the first limiting mechanism comprises vertical plates which are welded to the outer wall of the top of the bottom plate and are symmetrically distributed, a connecting column welded between the two vertical plates, and round pipes which are rotationally connected to the outer wall of the connecting column and are symmetrically distributed. The handle on the hydraulic support valve can be arranged in the U-shaped round steel by rotating the U-shaped round steel, the possibility of safety accidents caused by the fact that a worker mistakenly touches the handle and accordingl |
