Equipment special for disassembling and assembling coal mine underground comprehensive machine equipment

Abstract

The invention discloses equipment special for disassembling and assembling coal mine underground comprehensive machine equipment. The equipment comprises a deformation hoisting frame, a special operation vehicle and a hydraulic pump, wherein the deformation hoisting frame comprises an upper working frame and two side supporting frames; the upper working frame is provided with a width adjusting device; a side supporting frame is provided with a height adjusting device; the special operation vehicle comprises a vehicle plate; a supporting arm height adjusting device is arranged on the vehicle plate and is provided with a supporting arm; a pulley is arranged on the lower part of a transition beam of the upper working frame and is matched with a slide rail arranged on the upper part of the supporting arm of the operation vehicle; and the width L2 of the vehicle plate, the minimum width L1 of the upper working frame and the maximum width L3 of the upper working frame accords with a formula that L2 is less than L3 and more than L1. The hydraulic pump is connected to each cylinder of the adjusting device. The invention has the advantages that: space is saved, and the equipment can be adjusted according to the field working condition requirement, is easy and convenient to operate, has a high automatic degree, and conveniently disassembles, assembles and transports workpieces.

Description

technical field [0001] The invention relates to coal mine underground equipment, in particular to a special equipment for disassembling and assembling the coal mine comprehensive machine equipment. Background technique [0002] Most of the hydraulic supports used in coal mines are about 10 to 30 tons, and they play the role of supporting the roof of the coal mine. Below it is the unit for coal mining, and the lifting capacity of general mines is limited, so the hydraulic support used for coal mining must be disassembled into the well and then assembled, and the assembly must be disassembled before the well is lifted. At present, the domestic coal mines generally use simple tools (chain hoists) to assemble hydraulic supports underground, and there are the following problems: [0003] 1. People must operate under the heavy lifting parts, and their safety is threatened; [0004] 2. It is difficult to adjust, disassemble and assemble the lifted objects; [0005] 3. The labor ...

AI Technical Summary

Problems solved by technology

[0003] 1. People must operate under the heavy lifting parts, and their safety is threatened;

[0004] 2. It is difficult to adjust, disassemble and assemble the lifted objects;

[0005] 3. The labor efficiency is low, the labor intensity of the workers is high, and the labor input is large

[0006] The Chinese patent number is 91217179.0, and the utility model patent titled "Hydraulic support underground assembly platform" discloses a crane type structure, which needs to occupy a large space when lifting objects; there are also single hooks or double hooks, The hoisting rope and the slideway of the reducer also occupy a certain height (the cumulative height is more than 1 meter). Due to the limitation of the underground height, the use of this equipment requires deep excavation of the underground assembly cavern, which is not easy to realize in the underground.
