Double-cylinder hydraulic pin remover

Abstract

The invention relates to a double-cylinder hydraulic pin remover which belongs to the field of equipment for mine hydraulic supports, in particular to a device for pulling out a pin shaft for the mine hydraulic supports and large equipment, which comprises hydraulic jacks (5), a guide cylinder (11), a carrying and supporting base (9), a tension connecting rod (6), a guide ring (3), a bolt connector (7) and a tension connecting plate (4), wherein the carrying and supporting base (9) is arranged at the bottommost part, a connecting seat with the two hydraulic jacks and a passing-through hole when pulling out the pin shaft are arranged on the upper surface of the carrying and supporting base (9), a guide slot way and an operation hole for mounting the bolt connector are arranged on the upper surface of the guide cylinder, and the bolt connector can be connected with the pin shaft and the tension connecting rod together through the operation hole. The double-cylinder hydraulic pin remover has reasonable structure, convenient use, safety and reliability, and can integrate the functions of automation and large tension into a whole and solve the problems of time-consuming and effort-consuming properties, unsafety and the like in original manual hammering; furthermore, the device has beautiful and harmonic appearance and is safe and reliable.

Description

technical field [0001] The utility model relates to a double-cylinder hydraulic pin puller, which belongs to the field of equipment for mining hydraulic supports. Specifically, it is a mining hydraulic support and a pull-out device for large-scale equipment pins. Background technique [0002] The hydraulic support of the coal mining face relies on the high-pressure liquid, the column and the corresponding power jack to realize the four basic actions of lifting, pushing and moving. The connection of various moving parts is mostly connected by pivot pins. Due to the large volume and weight of the large hydraulic support, it cannot go up and down the well as a whole, so it must be separated to go up and down the well. This involves dismantling the various connecting pins on the hydraulic support, some of which are relatively large, and require more effort to disassemble after long-term use. As a result, the maintenance task of the support is aggravated, which will inevitably...

AI Technical Summary

Problems solved by technology

Due to the large volume and weight of the large hydraulic support, it is impossible to go up and down the well as a whole, so it must be separated to go up and down the well

This involves the disassembly of various connecting pins on the hydraulic support, some of which are relatively large, and are laborious to disassemble after long-term use

As a result, the maintenance task of the support is aggravated, which will inevitably bring a lot of labor intensity to the disassembly and maintenance of the hydraulic support, and the work safety factor is not high.
