[0002] Coal mine is a very important resource. When mining coal, it is necessary to drill out the mine hole first. After drilling out of the mine hole, the mine hole needs to be supported by hydraulic props. When supporting the hydraulic props, it may be due to the The loosening of the hydraulic props caused the hydraulic props to be subjected to a large force, causing the hydraulic props to tilt and unable to carry out the next step. At this time, it is necessary to manually adjust the inclined hydraulic props, but this method cannot guarantee that the upper soil will not Landslide phenomenon occurs, it is difficult to guarantee the life safety of workers, and the risk of work is increased. Aiming at the above shortcomings, the present invention improves

Embodiment Construction
[0020] Combine below Figure 1-7 The present invention is described in detail, wherein, for the convenience of description, the orientations mentioned below are defined as follows: figure 1 The up, down, left, right, front and back directions of the projection relationship itself are the same.
[0021] A quick recovery device when a hydraulic prop is tilted, as described in conjunction with accompanying drawings 1-7, includes a working box 12 and the working chamber 13, and the front and rear sides of the working box 12 are evenly provided with fixed cylinders 17, and the fixed cylinders 17 Clamping piston rods 20 are arranged close to each other on the end surfaces, and the clamping piston rods 20 are fixedly connected with the working box 12. The working box 12 can be separated from the front and back, and the lower end surface of the fixed cylinder 17 is provided with a fixed piston rod 18. The lower end surface of the fixed piston rod 18 is fixed with a fixed suction cup ...

The invention discloses a rapid restoration device for a hydraulic prop during inclination. The rapid restoration device comprises a working box and a working cavity, wherein fixed air cylinders are uniformly arranged on the front side and the rear side of the working box, clamping piston rods are arranged on the end surfaces, close to each other, of the fixed air cylinders, the clamping piston rods are fixedly connected with the working box, the working box can be separated front and back, and fixed piston rods are arranged on the lower end surfaces of the fixed air cylinders. After the rapidrestoration device is used, when the hydraulic prop is supported, the hydraulic prop can be fixed by the device, so that the support of the prop is guaranteed, and the working safety is improved; andwhen the hydraulic prop is inclined due to the fact that the upper soil is loosened, the device can automatically restore three hydraulic props at a time according to the inclination angle, manual adjustment is not needed, the working efficiency is improved, the risk of manual replacement is reduced, and the economic loss is reduced.
