Drilling type boring machine

Abstract

A drilling type boring machine is most suitable for digging a rock laneway of which the hardness f>8. The drilling type boring machine comprises a drilling mechanism and a boring machine. The drilling mechanism is fixed to a boring machine cantilever, and swings up and down and left and right along the boring machine cantilever. The drilling mechanism comprises a drilling mechanism main propulsion mechanism and a drilling mechanism attitude adjusting mechanism connected with the drilling mechanism main propulsion mechanism. For the rock drilling mechanisms of the same drilling type boring machine, three-degrees-of-freedom movement can be realized, the need for punching at all angles, in all positions and at all attitudes is satisfied, the two rock drilling mechanisms can work simultaneously, and the drilling efficiency is improved greatly. By reasonably integrating two rock drilling mechanisms on the boring machine, the boring machine has the functions of two rock drilling machines and one boring machine, and the drilling type boring machine greatly helps to save the roadway development cost. When an ordinary boring machine cannot conduct boring normally, a drilling work part drills a hole in the section of a roadway first to increase the free face of the rock so as to reduce the damage strength of the rock, and then, a boring machine cutting part develops the roadway.

Description

technical field [0001] The invention relates to a drilling-type roadheader, in particular to a roadway excavation suitable for hard rock formations with hardness f>8. Background technique [0002] Excavation after drilling holes in rock formations is an effective method to solve the difficulty of mining hard rock formations. Drilling type roadheader is a kind of tunneling equipment that can solve the difficulties of tunneling in hard rock formations. At present, mechanized tunneling can usually excavate with a hardness below f=8, so The current tunneling machinery not only has extremely low efficiency and increased energy consumption when tunneling f>8, but also the picks drop seriously and even make it impossible to tunnel. High-hardness rock roadway tunneling has become a bottleneck for the development of tunneling mechanization. Contents of the invention [0003] Technical problem: The purpose of the present invention is to overcome the deficiencies in the prior a...
