Comprehensive mechanical stone drift digging anchor machine

Abstract

The invention discloses a comprehensive mechanical stone drift digging anchor machine, which aims at solving the problems that in the traditional comprehensive mechanical stone drift digging anchor machine, the cutting ability is lower, the installation position of a top anchor rod anchor rope drilling machine is inappropriate, the whole stability of a device during the running is worse, and the like. The comprehensive mechanical stone drift digging anchor machine comprises a shovel board part, a crawler belt running part, a rack, a rotating part, a belt transporting part, a telescopic cutting part, a hydraulic drilling machine device, an advance supporting device, a top board supporting device, a bottom board supporting device, a hydraulic control system and an electrical control system, and is characterized in that the hydraulic drilling machine device is fixedly arranged at two side surfaces of a telescopic height adjusting rack of the telescopic cutting part, each side of the hydraulic drilling machine device comprises a group of top anchor rod anchor rope drilling machines, the top board supporting device is positioned at the middle part of a machine body, and the bottom board supporting device is positioned at the tail part of the machine body. By using a cutting device driven by a permanent magnet motor or a conventional cutting head, the cutting ability, the working efficiency and the whole stability of the device can be further increased.

Description

technical field [0001] The invention belongs to the technical field of coal mine underground development equipment, in particular to a comprehensive mechanized rock roadway bolter suitable for large, medium and small coal mine underground rock roadway mechanized development operations. Background technique [0002] In the field of coal mine development equipment technology, the traditional method of tunneling in various mines is mainly blasting, and the support methods are combined support of bolts, anchor cables, joists, and anchor nets. The gun excavation is drilled, charged, and blasted with an air-leg pneumatic drill; the gangue falling from the blasting is first manually crushed and then transported out of the working face by a rock rake machine; support. There are many problems in the tunneling construction method of Fangpaoyan Roadway, such as small tunneling section, non-mechanized operation, slow construction speed, low efficiency, low safety factor, and poor opera...

AI Technical Summary

Problems solved by technology

However, due to the complex geological conditions of the coal mine, there are still many deficiencies in the industrial test operation of this machine, such as the low cutting capacity of the cutting cutter head device, the inappropriate installation position of the roof bolt and cable anchor drilling rig, and The overall stability of the runtime is poor, etc., which requires in-depth research and continuous improvement
