Mine comprehensive mechanized coal mining equipment assembling-disassembling lifting device

Abstract

The invention discloses a mine comprehensive mechanized coal mining equipment assembling-disassembling lifting device. The lifting device comprises two bases which are parallelly arranged side by side; each base is fixedly provided with a bottom frame, a plurality of pillar sockets are fixedly arranged in the middle of the interior of the bottom frame in the extending direction of the bottom frame, hydraulic pillars are vertically and fixedly arranged in the pillar sockets, a top plate is fixedly connected to the top ends of pistons of the hydraulic pillars, and the two sides of the top plateare fixedly provided with hanging pulleys correspondingly; hydraulic cylinders opposite in direction are fixedly arranged on the two sides of the interior of each bottom frame in the extending direction of the bottom frame, the top ends of pistons of the hydraulic cylinders are fixedly connected with pull wheels and guide wheels, one ends of steel wire ropes are connected to the pull wheels, the other ends of the steel wire ropes are wound around the hanging pulleys located on the top plate through the guide wheels and then hang down, and the ends of the lower portions of the steel wire ropesare connected with hooks. The mine comprehensive mechanized coal mining equipment assembling-disassembling lifting device can be suitable for the working environment space wide in site condition rangeand is convenient to repair, transport and install.

Description

technical field [0001] The invention belongs to the technical field of assembling and disassembling lifting devices for fully mechanized mining working faces in underground coal mines. Background technique [0002] With the promotion of safe and efficient work in coal mines, there are more and more comprehensive mechanized coal mining faces, the use of fully mechanized mining equipment is increasing, and the number of relocation and installation of fully mechanized mining equipment is gradually increasing. Assembled to form a complete machine and applied to the coal mining face, on the other hand, the complete machine needs to be disassembled, lifted and moved. The frequency of use of the lifting device of large-scale fully mechanized mining equipment is also gradually increasing. The current hoisting device for fully mechanized mining equipment includes: four columns, four top beams, and four hydraulic cylinders. The four top beams are assembled to form a rectangular struct...

AI Technical Summary

Problems solved by technology

Since the current lifting device is affected by many factors of the underground working environment, such as: site height, width, transportation, etc., there are many inconveniences and unsafe factors, and the column is too large, and its height is generally more than four meters. Difficulty, it is not easy to handle after the steel wire rope falls out of the pulley; especially for different heights and widths of the coal mining face space on site, it is necessary to process and install the assembly and disassembly lifting devices of different heights and widths, resulting in repeated waste and not convenient to use
