Automatic tunnel drilling machine and method

Abstract

The invention discloses an automatic tunnel drilling machine and method. The drilling machine comprises a track vehicle chassis, a control supporting box, a hydraulic control box, a central supportingshaft, a transverse shaft, an electric drill, a positioning detection mechanism and an electric drill fine-adjusting device, wherein a drill bit of the electric drill is provided with a limiting sensor and a speed sensor. The method comprises the steps that 1, hole position marks are arranged; 2, the drilling machine executes automatic drilling in a tunnel section; 3, the drilling machine executes automatic tunnel drilling; 4, troubleshooting is executed. Movement of the drilling machine in the length direction of a tunnel is achieved through the track vehicle chassis, coarse alignment for drilling is achieved, the bearing capacity is large, fine alignment for drilling is achieved through a planar movement mechanism, control is simple, microcosmic fine alignment for drilling is achieved through the cooperation of a dip angle adjusting oil hydraulic cylinder and a main oil cylinder, effort is saved, operation is accurate, labor is saved, the safety risk and construction difficulty arereduced, a large amount of dust is prevented from being inhaled during manual operation, and the harm to body health of constructors and unnecessary personal injuries are decreased.

Description

technical field [0001] The invention belongs to the technical field of tunnel automatic drilling, and in particular relates to an automatic tunnel drilling machine and method. Background technique [0002] When the auxiliary facilities on the inner wall of the tunnel are installed on the inner wall of the tunnel, it is necessary to drill installation holes on the inner wall of the tunnel first. However, there are many types of auxiliary facilities on the inner wall of the tunnel, and the number is large. The demand for installation holes on the inner wall of the tunnel is large. Drilling is manual work, the construction is very dangerous, the construction is difficult, the work efficiency is low, the labor intensity is high, a large amount of dust is generated during construction, the environmental conditions are poor, and the health of the construction workers is greatly damaged. In order to improve work efficiency and reduce Safety risks, there is an urgent need for an aut...
