Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic supports, and in particular relates to an electro-hydraulic controlled hydraulic support for mining. Background Art

[0002] The hydraulic support is a structure used to control the mine pressure at the coal mining face. The mine pressure acts on the hydraulic support in the form of external load. In the use of existing mine hydraulic supports, the electro-hydraulic control method is used to control the hydraulic support in the mine.

[0003] In a Chinese patent with publication number CN218235156U, an electro-hydraulic controlled mining hydraulic support is mentioned, comprising a base, both sides of the top of the base are fixedly connected to a hydraulic cylinder, the top of the hydraulic cylinder is fixedly connected to the hydraulic support body, and the bottom of the inner cavity of the base is fixedly connected to a drive box. The utility model solves the problem that the prior art electro-hydraulic controlled mining hydraulic support is not easy to move, and during the process of mining the coal seam, the hydraulic support needs to be adjusted according to the mining location; however, when the hydraulic support is in use, its top supports the working surface in the mine through a separate support plate, and its supporting force is concentrated in the middle, resulting in poor support effect of the device on the working surface in the mine;

[0004] In addition, when positioning the hydraulic support, the moving wheels must be retracted first so that the bottom end of the base is in close contact with the ground in the mine to prevent the device from shifting. However, no auxiliary support structure is set during use, resulting in poor bottom stability of the device when in use, which is not conducive to supporting the working surface in the mine and reduces the safety of work in the mine.
