Integrated forepoling for reversed loader head

Abstract

The integrated forepoling comprises a top beam, vertical guide cylinders are arranged at the positions, located on the front side and the rear side of a motor of the reversed loader, below the top beam respectively, column shoes are arranged below the guide cylinders, and a transverse fixing plate is arranged in the middle of each guide cylinder. An upper stand column is arranged at the position, located above the fixing plate, in the guide cylinder and used for driving the top beam to move up and down. A lower stand column is arranged at the position, below the fixing plate, in the guide cylinder and used for driving the column shoe to move up and down. The reversed loader machine head and the forepoling are integrally designed, when the reversed loader machine head moves, the forepoling moves along with the reversed loader machine head at the same time, a traditional frame moving mechanism does not need to be additionally arranged, and therefore the forepoling is compact in structure and small in occupied roadway space; the problem that the width of a roadway needs to be increased temporarily when a forepoling is arranged at the head of a reversed loader in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of roadway support equipment for fully mechanized mining and fully mechanized caving working faces in underground coal mines, in particular to an integrated advanced support for the head of a loader. Background technique [0002] The strengthening support (including end support and advanced support) of the transportation roadway in the fully mechanized mining and fully mechanized caving face of coal mines has always been an important link affecting the safe and efficient mining of coal. Support must be strengthened within 20m of the connection between the exit and the roadway; the "Notice of the State Coal Mine Safety Supervision Bureau on Strengthening the Prevention and Control of Rock Burst in Coal Mine" stipulates that mines with rock burst regulations and coal mining face with impact danger are safe exits The advanced support range at the connection with the roadway shall not be less than 70 meters, and...

AI Technical Summary

Problems solved by technology

[0003] When the advance support range is required to be large, the head of the loader is usually included. However, the head of the loader is usually the widest part of the entire loader. For the transport roadway with a small width, the head of the loader usually cannot be arranged Conventional two-frame, single-row or other forms of advanced supports still use single hydraulic props for reinforced support, which cannot meet the relevant regulations of administrative departments at all levels for advanced support and the requirements for intelligent working face construction

At present, for the advance support at the head of the loader, there is no other feasible technical solution except increasing the width of the roadway to arrange the advance support
