Problems solved by technology

However, the mechanism needs to cooperate with the drilling rig, the operation is a bit complicated, the maintenance is inconvenient, and the number of workers required is large, etc.
[0008] More advanced tunneling equipment with cable and bolt support functions, such as bolters, can simultaneously realize the functions of tunneling and cable and bolt support, but only part of the top bolt and cable support and Supporting the support of anchor rods and cables, and most of the support of anchor rods and cables is carried out by workers after drilling holes on the bolter rig, and uploading the anchor cables and rods with their hands. For the workers, the workload is heavy and time-consuming Laborious, and requires workers to work in groups, labor intensity is high, the working environment is harsh, and safety is poor

Abstract

A device for assisting coal mine roof timbering anchor cable feeding comprises a support, a lower clamping mechanism and an upper clamping mechanism. The lower clamping mechanism is arranged on the support, the upper clamping mechanism is arranged on the lower clamping mechanism and comprises an upper frame, and an air motor for providing power for the upper clamping mechanism and the lower clamping mechanism is fixedly arranged on the right side of the upper frame. The device is novel in design, easy to operate, high in automation degree, small in labor number, low in labor intensity, low in manufacturing cost, safe, reliable, good in market prospect and easy to popularize and apply.

Description

technical field [0001] The invention belongs to the technical field of coal mine safety production, and in particular relates to a coal mine roof support anchor cable auxiliary feeding device. Background technique [0002] With the development of my country's coal industry, the industrial policy requirements for the coal industry, my country's coal industry's backward excavation technology has seriously affected the development of the industry, and mining imbalance has become an important reason for restricting coal production. In roadway excavation operations, The operating rate of the roadheader is only about 30%, and most of the time is used for support. The low support efficiency is the most important factor affecting the tunneling and mining. [0003] As an active support method, anchor cable support has the characteristics of large bearing capacity, safety and reliability. It has developed rapidly in my country in recent years and has been widely used in mine roadway su...
