Shed upper beam device of I-beam shed for coal mine laneway

Abstract

The invention relates to a shed upper beam device of an I-beam shed for a coal mine laneway, which includes a cantilever, wherein the cantilever is arranged in a sleeve; the sleeve is hung on an erected I-beam shed upper beam through a fixator; a propulsion support is hung on the erected I-beam shed upper beam; the rear end of the cantilever is connected with the propulsion support through a propulsion device; the front end of the cantilever is hinged with the rear end of a height adjusting arm; the height adjusting arm adopts a hollow structure, and is internally provided with a width adjusting device, a connecting rod and an outrigger device; the rear end of the width adjusting device is fixed with the inner bottom surface of the height adjusting arm; the front end of the width adjusting device is connected with one end of the connecting rod through a width universal joint; the other end of the connecting rod is fixed with the outrigger device; and the bottom of the height adjusting arm is connected with the front lower part of the cantilever through a height adjusting device. The I-beam shed upper beam can be installed through firstly adjusting the mounting position of the I-beam shed upper beam through the width adjusting device and the height adjusting device, and finally through manually fixing the I-beam shed upper beam.

Description

Technical field: [0001] The invention belongs to the technical field of tools for erecting coal mine roadways, and in particular relates to a shed upper beam device used for erecting an I-shaped steel shed of a coal mine roadway. Background technique: [0002] With the increase of coal demand and the decrease of coal resources year by year, coal mining enterprises have to shift their mining targets to some coal fields with poor geological conditions, complex geographical environment and difficult mining. Some large enterprises have even begun to mine thousands of meters In the coal fields below, the increase in mining difficulty will inevitably bring greater safety hazards to the mining work. At the same time, the state requires more equipment and less labor for coal mining, improve the degree of mechanization of mining, and ensure the safety of mining personnel as much as possible. , in order to achieve the above-mentioned purpose, existing coalfield mining work drops int...

AI Technical Summary

Problems solved by technology

[0004] As the size of the I-shaped steel shed increases, its own weight must be heavier. A 12# I-shaped steel shed weighs more than 100 kilograms. Currently, the existing roadway is being erected Most of the I-steel sheds are erected manually. To erect the upper beam of an I-steel shed requires four or five workers to work together. Therefore, it is an urgent technical problem to be solved for technicians in the coal industry to develop a kind of I-steel shed erection equipment to replace manual operation.
