Problems solved by technology
In the manual lifting method, two people are generally required to lift the pin shaft, which is labor-intensive and high-risk for the workers; in the lifting method of the chain hoist, limited by the underground environment, the rooting of the chain hoist above the pin hole is limited. It is difficult to select the point, the most common situation is that there is no very suitable lifting point to hang the chain hoist, so the operation is difficult and the efficiency is low

Abstract
The invention provides an auxiliary device for downhole assembly of a hydraulic support. The auxiliary device comprises a base (6), a lifting piece and a hinge pin bearing piece (1), wherein the base (6) is provided with a wheel; the bottom end of the lifting piece is fixedly connected with the base (6); the top end of the lifting piece can move in the vertical direction; the hinge pin bearing piece (1) is rotationally connected with the top end of the lifting piece; the hinge pin bearing piece (1) rotates relative to the lifting piece around a vertical axis. The auxiliary device can conveniently lift a heavy hinge pin, thereby improving the work efficiency for the downhole assembly of the hydraulic support.
Description
technical field [0001] The invention relates to the technical field of hydraulic supports, in particular to an auxiliary device for assembling hydraulic supports downhole. Background technique [0002] With the rapid development of science and technology in our country, the coal mining equipment used in coal mines is becoming more and more large-scale and integrated, especially the hydraulic supports, shearers, conveyors and other equipment used in underground coal mining faces. Large-scale and heavy-duty development. However, the hoisting capacity of the hoist in the auxiliary shaft of the mine has been fixed at the beginning of mine construction, and it is difficult to improve its transportation capacity through later equipment upgrades, which seriously restricts the overall operation of the equipment. It is a rigid requirement that the disassembled parts be reassembled underground. [0003] During the underground assembly process of the hydraulic support, the size and d...
