Tunneling device for hard rock body

Abstract

The invention discloses a tunneling device for a hard rock body. The tunneling device comprises a right rock body drilling, fracture generation and abrasive jet mechanism, a left rock body drilling, fracture generation and abrasive jet mechanism, a hydraulic impact hammer, a right multi-degree-of-freedom mechanical arm, a left multi-degree-of-freedom mechanical arm, a middle multi-degree-of-freedom mechanical arm, a main machine frame, a loading mechanism, a crawler walking mechanism, a conveying mechanism, a high-pressure abrasive jet generating system and a hydraulic pump station. The rightrock body drilling, fracture generation and abrasive jet mechanism and the left rock body drilling, fracture generation and abrasive jet mechanism use abrasive jet assisted drilling and high-pressureabrasive jet to conduct rock body fracture generation, the cutting resistance of the hard rock body can be reduced to the largest extent, the difficulty of mechanical cutting teeth in crushing hard rock is reduced, and the crushing efficiency of the hard rock is improved. The crushing difficulty of the hard rock can be reduced, the crushing efficiency of the hard rock is improved, excessive abrasion of a drill bit during work of the mechanism can be avoided, and the tunneling device plays an important role in achieving efficient tunneling of hard rock roadways and tunnels.

Problems solved by technology

However, in the excavation construction of hard rock mass, the existing equipment has increased tool wear, reduced reliability and work efficiency. How to achieve efficient crushing of hard rock has become an urgent problem and difficult problem to be solved. It is urgent to study new rock crushing methods to achieve The efficient crushing of hard rock is of great significance to the efficient mining of mines, efficient tunneling and even the efficient development of my country's energy resources.

[0003]In the past, mechanically crushing hard rocks was achieved mainly by increasing the mechanical driving power, but the rock-breaking ability of mechanical picks has not changed, and only increasing the power will lead to the failure of the rock crushing mechanism. Aggravated wear and increased amount of dust in the working flour make it difficult to effectively improve the rock-breaking efficiency of the machine and increase potential safety hazards
