Tunneling and anchoring machine

Abstract

The invention provides a tunneling and anchoring machine. A cutting part and a drilling and anchoring platform of the tunneling and anchoring machine can move back and forth on the tunneling and anchoring machine. The tunneling and anchoring machine comprises the cutting part, a shovel plate part, a conveyor, an electrical system, a hydraulic system and a body part, wherein the body part is provided with the electrical system and the hydraulic system; and the conveyor is connected with the body part. The tunneling and anchoring machine is characterized in that the body part comprises an upperbody part and a lower body part connected with the upper body part; the lower body part comprises a rack and a crawler walking mechanism connected with the rack; the upper body part and the lower bodypart are respectively connected with a linear driving device; the cutting part is connected with the upper body part; the shovel plate part is connected with the lower body part; and the tunneling and anchoring machine also comprises the drilling and anchoring platform connected with the lower body part. The tunneling and anchoring machine provided by the invention can be used for quickly tunneling a roadway and supporting a bolt.

Description

Technical field[0001]The invention relates to a boring anchor machine suitable for tunneling of mines, tunnels and related engineering roadways.Background technique[0002]At present, mine mining, especially coal mine tunnel excavation and bolt support, adopt the method of tunneling forward, generally no more than 2 meters, and stopping when it moves backward. Support personnel carry pneumatic or hydraulic drilling rigs and supporting materials to the front end of the tunneling machine. The roof and the two sides of anchor rods support high labor intensity and low construction efficiency. In roadway excavation and bolt support, the operating rate of the roadheader is only about 30%, that is, two-thirds of the time is used for artificial bolt support, and the efficiency of roadway excavation is low.[0003]In recent years, there have been installations of anchoring mechanisms on both sides of the cutting arm of the roadheader, such as the publication number CN107420101A, a cutting part w...

AI Technical Summary

Problems solved by technology

[0002] At present, mine mining, especially coal mine roadway excavation and bolt support adopt the method that the roadheader generally does not exceed 2 meters in advance, and then stops when it retreats. The support personnel carry the dynamic or hydraulic drilling rig and support materials to the front end of the roadheader for Roof and two sides of bolt support, high labor intensity and low construction efficiency

In roadway excavation and bolt support, the operating rate of the roadheader is only about 30%, that is, two-thirds of the time is used for artificial bolt support, and the efficiency of roadway excavation is low

[0003] In recent years, anchoring mechanisms have been installed on both sides of the cutting arm of the roadheader, such as the publication number CN107420101A, which has a cutting part with anchoring and supporting functions. Although part of the labor intensity of the operators has been reduced, when the roadheader is working , the vibration of the cutting arm is very large, the anchor installation and jacking mechanism are easily damaged, and the bolt support on the side wall within 1 meter close to the roadway floor cannot be constructed, and a manual hand-held rock bolter is required to carry out the secondary bolting at the bottom of the side wall construction

[0004] There is also a top bolter installed on the front side of the roadheader body part, and a side bolter installed on the top surface of the rear part of the body, such as the announcement number CN102364053B bolter, although it solves the problem that the bolter is installed on the side of the cutting arm , the cutting arm vibration damages the bolter when the roadheader is working, but the top bolter cannot perform roadway side bolt support, and the side bolter cannot perform roadway roof bolt support; although the side bolter can Lifting, but the side bolter is located on the top surface of the rear part of the main body installed on the walking part. When the side bolter is at the lowest position for side bolting, the side bolting near the bottom plate cannot be constructed.

The distance between the temporary support connected to the walking track frame and the front end of the cutting part is long, the longitudinal distance of the supporting roadway is short, and the roadway roof has a long distance in an empty state without any support, which is not conducive to the safety management of the roadway roof
