Technical Field

[0001] The utility model relates to the technical field of mining machinery, in particular to a thin coal seam multi-channel hydraulic support. Background Art

[0002] Hydraulic support is a structure used to control the mine pressure of coal mining working face. The mine pressure of the mining face acts on the hydraulic support in the form of external load. In the mechanical system of interaction between the hydraulic support and the surrounding rock of the mining face, if the combined force of each support of the hydraulic support and the combined force of the external load acting on the hydraulic support by the roof are exactly in the same straight line, then the hydraulic support is very suitable for the surrounding rock of the mining face.

[0003] Existing hydraulic supports are generally large in size. When thin coal seams need to be supported, operators are usually required to use cranes and other handling equipment to transfer the hydraulic supports to a designated location to support the thin coal seams. The process is cumbersome and involves a certain degree of danger. For this reason, we propose a multi-channel hydraulic support for thin coal seams. Utility Model Content

During the start-up process of the electric telescopic rod 215, the movable plate 212 will be propped up, and then the electric telescopic rod 1 214 can be turned on. After the electric telescopic rod 1 214 is started, the support plate 213 will be pushed to make the support plate 213 rotate around the movable plate 212, so that the thin coal seam can be supported by the support plate 213.

[0026] Example 2

[0027] On the basis of Example 1, a preferred embodiment of a thin coal seam multi-channel hydraulic support provided by the utility model is as follows: Figures 1 to 4 As shown: the fixing mechanism 22 includes a vertical rod 221 fixedly installed at the bottom of the mounting plate 1, a universal wheel 222 is fixedly installed at the bottom of the vertical rod 221, a fixing plate 223 is fixedly installed on the bottom outer wall of the vertical rod 221, a screw rod 224 is threadedly connected to the inner wall of the other end of the fixing plate 223, an adjustment handle 226 is fixedly installed on the top outer wall of the screw rod 224, and the other end of the screw rod 224 is rotatably connected to a limiting plate 225.

After the electric telescopic rod 1 214 is started, the support plate 213 will be pushed to rotate around the movable plate 212, so that the thin coal seam can be supported by the support plate 213. When it is necessary to transfer the device, the operator can rotate the adjustment handle 226. During the rotation of the adjusting handle 226, the screw rod 224 will also rotate, and after the screw rod 224 rotates, the limit plate 225 will move upward. When the limit plate 225 is separated from the limit on the ground, the operator can push the device to transport the device. After the transportation of the device is completed, the operator can reverse the adjusting handle 226.
