The invention discloses a large mining hydraulic support pin shaft dismounting device, and belongs to the field of hydraulic support dismounting. The large mining hydraulic support pin shaft dismounting device comprises a pushing sleeve and a pulling sleeve; the pushing sleeve and the pulling sleeve are located on the two sides of the hydraulic support correspondingly; a first hydraulic rod worksto apply upward force to the pushing sleeve, a second hydraulic rod exerts downward force to the pulling sleeve, the pushing sleeve and the pulling sleeve are in tensioned connection through a steel cable rope and a movable pulley, two forces mutually act, force, ejecting on the hydraulic support, of the pushing sleeve by a worker can be effectively reduced, labor intensity is reduced, the movablepulley facilities force saving, the pushing sleeve and the pulling sleeve are in tensioned connection, during dismounting, a pin shaft is pulled to be detached through a thread connection column, thepin shaft is pushed through a first hydraulic push rod in the pushing sleeve, the acting force of the thread connection column for pulling the pin shaft is effectively reduced, and wire sliding is prevented.
Description
technical field [0001] The invention relates to the field of dismantling of hydraulic supports, and more specifically relates to a large-scale mining hydraulic support pin dismantling device. Background technique [0002] The hydraulic support is a commonly used support equipment for coal mining in coal mines, and the hydraulic support is a four-bar linkage mechanism connected by pin shafts. As the specifications and models of hydraulic supports become larger and larger, the connecting pins between various structural components are also getting larger and larger. The parts in mining production machinery and equipment are often connected by pins. Due to the large resistance, the pins are often affected. Therefore, it is necessary to repair these, which requires the disassembly of the damaged pin shaft. In the disassembly and replacement of the pin shaft, the special tool - belt hammer is not only labor-intensive, but also has a low work safety factor. At present, there are hy...
