Problems solved by technology

The main problem is that the top bolt and the anchor cable cannot work in parallel, and it is difficult to adjust the length of the CHDDR roof bolt machine body
The support time is too long; the advanced support is a conjoined type, which has poor adaptability to the situation where the roof condition is not good; the body is too long, and the adjustment speed is slow; it is inconvenient to move the drill when the single drilling rig is supported, and the labor intensity of the workers is high. The support speed is slow, and it is not suitable for the support requirements of Sihe Mine with large cross-section and multiple processes.

Abstract

The invention is a self moving bolting machine. The character is: it has two drilling devices, two leading timberings, track moving mechanism, integral moving slide channel and platform; the moving mechanism is made up of hydraulic motor driving, the frame of the moving mechanism is assembled with bolting machine platform; two sides of the far end of the platform are assembled with two hydraulic oil cylinder type leading timberings, two frame drilling devices are assembled behind the leading timberings; the platform is arranged with integral parallel mobile channel of the drilling device, the drilling device is assembled on the mobile channel. Each drilling device includes a vertical pile, a frame parallel mobile device, 45 degrees of frame rotating device, 8 degrees of pendulum oil cylinder and connecting earring, three-grade frame, drill hydraulic motor device. The operation is simple, the efficiency is high.

Description

technical field [0001] The invention belongs to tunnel construction machinery, and in particular relates to a self-moving walking bolter, which is mechanical equipment used for tunnel, mine roadway and roadway roof support. Background technique [0002] At present, in order to improve the level of continuous excavation in the coal mining operation of coal mines, realize the parallel operation of excavation and support of fully mechanized excavators, and realize the parallel operation of the three processes of top, side, and anchor cables, the bolt support equipment is required to be modernized. DBT-J.H.Fletcher CHDDR type roof bolter, main structure: electrical part, pump, motor and blower part, drill and cantilever part, valve part, running parts. The main problem is that the top bolt and the anchor cable cannot work in parallel, and it is difficult to adjust the length of the CHDDR type roof bolt machine body. The support time is too long; the advanced support is a conjoi...
