Circulating-moving type horizontally-arranged air way forepoling unit

Abstract

Disclosed is a circulating-moving type horizontally-arranged air way forepoling unit. The circulating-moving type horizontally-arranged air way forepoling unit comprises a plurality of forepoling modules which are arranged in the longitudinal direction of a roadway at intervals. A frame-moving vehicle is arranged on the lower portion of each forepoling module and used for moving the last forepoling module to the forefront. Each forepoling module comprises two telescopic stand columns which are arranged on the two sides of the roadway. The bottoms of the telescopic stand columns are provided with bases. The tops of the two telescopic stand columns are connected through a top beam. According to the circulating-moving type horizontally-arranged air way forepoling unit, the degree of automation is high, the intensity of protection is greatly improved, the stable performance is greatly improved, anchor rods and anchor cables are not needed to be disassembled during using, the all forepoling modules do not needed to be moved during moving, the moving efficiency is high, angles and positions of the conveyed forepoling modules can be adjusted, the adaptability is higher, braking is timely and stable, the safety is greatly improved, time and labor are saved, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of advanced support groups used in coal mines, in particular to a circularly movable type horizontally arranged advanced support group for air lanes. Background technique [0002] The advanced support group is an indispensable supporting equipment for comprehensive mechanized coal mining. The advanced support group is composed of several advanced support units arranged and connected. The advanced support group effectively supports the roadway of the coal mine when in use. However, the advanced stent group currently used still has the following technical problems. [0003] 1. The advanced support unit of the advanced support group is vertically arranged along the roadway direction, and the actual contact area between the top beam of the advanced support unit and the roadway is very small, resulting in low support strength. [0004] 2. Every time the advanced support group moves, all the advanced support unit...

AI Technical Summary

Problems solved by technology

[0003] 1. The advanced support unit of the advanced support group is arranged vertically along the direction of the roadway, and the actual contact area between the top beam of the advanced support unit and the roadway is very small, resulting in the support strength Small

[0004] 2. Every time the advanced support group moves, all the advanced support units need to complete the process of lowering, moving and lifting. The roof is seriously broken, so it is necessary to repair the roadway roof frequently, which is time-consuming, laborious, increases production costs, and reduces production efficiency

[0005] 3. The automation degree of the advanced support group is low. The moving vehicle used to move the advanced support unit needs to be moved by manpower during use, and the moving speed is slow and the efficiency is low. , time-consuming and labor-intensive, when the space of the roadway changes or encounters other mining equipment and the leading support unit cannot pass through, the moving vehicle cannot adjust the angle and position of the leading support unit, and manual adjustment is required, which greatly reduces the moving efficiency and thus reduces In order to reduce production efficiency, the brakes of the moving truck are unstable and not timely, and the parking position is not accurate. Especially when the moving truck passes through a roadway with a slope, it is difficult to stop and accidents are prone to occur.

[0006] 4. The connection between the advanced support units is unstable, and the force on the base is unreasonable and easy to deform, which leads to the low stability of the advanced support group and is prone to Dumping, leaving a safety hazard

[0007] V. The layout of the advanced support unit and the top beam structure of the advanced support unit are unreasonable, so that the advanced support unit is in contact with the anchor rod and anchor cable in the roadway during use. If the position conflict occurs, if the anchor rod and anchor cable are not removed, the effect of the leading support unit on the top will not be good, which will greatly reduce the support performance. If the anchor rod and anchor cable are removed, a lot of time will be wasted and production will be seriously affected
