Problems solved by technology

[0002] The use of large mining height hydraulic supports is becoming more and more widespread. With the increase of mining height, the support height, working resistance and single frame weight of hydraulic supports are also getting higher and higher. Therefore, the base and connecting rods are connected with pins, shielding beams and connecting rods. The size of the connecting pin shaft, the connecting pin shaft between the cover beam and the top beam is also getting larger and larger. When the bracket needs to be overhauled in the well or overhauled underground, the removal of the large pin shaft is mostly done by manual brute force, the disassembly efficiency is low, and the safety hazard is great. It is the key link that troubles the smooth disintegration of the hydraulic support, and it is more laborious to disassemble after long-term use, which leads to the aggravation of the maintenance task of the support and brings great labor intensity to the disassembly and maintenance of the hydraulic support

Abstract

The invention relates to the technical field of mining equipment and provides a mining support pneumatic pin puller. The mining support pneumatic pin puller comprises a pull-out air cylinder and a supporting device which are detachably assembled together. The pull-out air cylinder comprises a cylinder body. A hollow piston rod is sleeved with the cylinder body in a sealed manner, and the rear endof the cylinder body is detachably and fixedly provided with a guide end cover. A pull rod is sleeved with the hollow piston rod, the rear end portion of the pull rod is provided with a pull rod adjusting device, the rear end of the pull rod is provided with a limiting nut in a screwed manner, the front end of the pull rod is provided with a pull head in a screwed manner, and the power output endof the pull head is provided with an outer thread. The supporting device comprises a supporting pedestal detachably installed at the front end of the cylinder body, and the supporting pedestal is provided with at least two arc-shaped supporting plates in a sliding manner, and openings of the arc-shaped supporting plates are inward. The mining supporting pneumatic pin pulley is convenient to carryand use, high in pin pulling efficiency, wide in application range and convenient to use and popularize.
