Integrated tunnelling and anchoring machine

Abstract

The integrated tunneling and anchoring machine with integrated structure of a tunneling machine and an anchoring machine has foldable anchoring machine installed hydraulically on the turntable side wall of the tunneling machine and can realize the automatic hydraulic control of the anchoring machine work position and work program. The present invention has the turntable of the tunneling machine for locating and the guard sheet in the cutting unit of the tunneling machine as operating platform, so that it has greatly simplified tunneling and anchoring machine design. The present invention has the functions of back and forth telescoping, wagging, vertical height regulation, etc. During tunneling, the anchoring machine may be folded to reduce occupied space.

Description

technical field [0001] The invention relates to coal mine roadway excavation, mining and supporting machinery, in particular to a bolter digging machine, a new integrated model of digging and bolting, which realizes the integrated effect of the tunneling machine and the bolter. Background technique [0002] At present, the support work of the roadheader after tunneling is a difficult, complicated and extremely inefficient work. The main reason is that the separate work of the roadheader and the bolter has caused a lot of waste of time, and the effective working time ratio is very small. Manual bolting is not only labor-intensive, but also inefficient. Therefore, there is a great need for an airborne bolter that can immediately perform bolting work after the tunneling machine excavates, so as to improve the working efficiency of the tunneling machine and reduce the number of operators. labor intensity. [0003] The Chinese utility model patent (application number CN92243425....

AI Technical Summary

Problems solved by technology

[0005] 1. Installed on the upper part of the rotary table of the roadheader, the empty head distance is limited, and the low roadway bolt cannot be drilled

[0006] 2. The rock bolt rig has no self-rotating device, so the angle bolt cannot be drilled

[0007] 3. The function of the cutting part of the roadheader is not used, and there are few positions for bolting

[0008] 4. The cantilever of the main arm is too long and the stability is not good

[0009] 5. Only suitable for roadways with rectangular or trapezoidal sections

[0012] 1. Installed on the rotary table of the roadheader, the height of the whole machine is too high, which will affect the working performance of the roadheader

[0013] 2. The cantilever of the main arm is too long and the stability is not good

[0014] 3. The whole machine is a single anchor, and the work efficiency is low

[0015] 4. The working position of the bolter is high, and the scope of applicable roadway is small

[0018] 1. The bolter has an independent hydraulic station, operating table, etc., resulting in two hydraulic stations on one machine, which costs a lot and takes up a lot of space

[0019] 2. The cantilever of the main arm is too long and the stability is not good

[0020] 3. The height of the whole machine is too high, the volume and quality are too large, the structure is complicated, and the operation is inconvenient

[0021] 4. The corner bolt cannot be drilled, and the applicable roadway range is small

[0024] 1. The bolter is installed on the rotary table of the roadheader, and the height of the machine is too high, which affects the performance of the roadheader

[0025] 2. The cantilever of the main arm is too long and the stability is not good

[0026] 3. There is no support when the side anchor is installed, and the failure rate is high during work.

[0027] 4. The working position of the bolter is too high to be suitable for bolting operations in low roadways
