Underground coal mine large channel end socket suspension hydraulic support

Abstract

The invention discloses an underground coal mine large channel end socket suspension hydraulic support, which relates to mine equipment. The underground coal mine large channel end socket suspension hydraulic support is characterized in that the end part of each of a left top beam and a right top beam is supported by a hydraulic prop I, and the middle-part top beam is supported by five hydraulic props II; a supporting bracket is arranged at the lower part of the middle-part top beam, and is connected with the middle-part top beam through a supporting bracket floating guiding component in a sliding manner; a gap is formed between the supporting bracket and the middle-part top beam, so that supporting bracket beams and the middle-part top beam can float up and down; and the left top beam and the right top beam are connected with end parts of the supporting bracket beams through a supporting bracket floating component, and gaps are formed between the supporting bracket and the left top beam and between the supporting bracket and the right top beam, so that the supporting bracket beams, the left top beam and the right top beam can float up and down. When a working face extends forward, continuous supporting of the top plate at the end socket and mechanical moving of equipment are realized through alternate forward-moving of the left top beam and the right top beam on the two sides and the middle-part top beam; the middle-part top beam has excessive width, so that problems that the reversed loader cannot be mounted and the equipment cannot be matched are solved; and complete mechanized operation for supporting and moving of the support is realized, so that labor intensity of workers is greatly relieved, and safety performance and labor efficiency are improved.

Description

technical field [0001] The invention relates to mining equipment, in particular to a suspended hydraulic support for supporting the end of a large channel in a coal mine underground working face. Background technique [0002] The intersection of the coal mining face and the mining roadway in the coal mine is called the end, and the support used for the end is called the end support. The end part is the intersection point of equipment such as scraper conveyor and transfer machine, and it is also the throat part of pedestrian passage, ventilation, material transportation and coal transportation. The quality of the end support is the key to determine whether the working face can operate normally. According to the statistics of the relevant safety department, the personal casualty accidents at the end account for more than half of the underground accidents. For example, the end support method consisting of a single hydraulic prop and a top beam is used for support in the genera...

AI Technical Summary

Problems solved by technology

For example, the end support method consisting of a single hydraulic prop and a top beam is used for support in the general mining face, the safety performance of the support is poor, the labor intensity of the workers is high, and the support work efficiency is low

[0003] In recent years, a new type of supporting equipment, integral top beam combined suspension hydraulic support: has been popularized and used in coal mines, but the method of end support is to use two sets of integral top beam combined suspension hydraulic supports in parallel for use, because each The distance between the centers of the two hydraulic props in the width direction is relatively small, which makes it impossible to install the reloader, which brings inconvenience to the use
