Abstract

The invention relates to drilling equipment, in particular to drilling equipment for tunnel excavation. According to the drilling equipment for tunnel excavation, manual drilling is not needed, and the state after adjustment can be kept for automatic drilling. Drilling equipment for tunnel excavation comprises a base, and universal wheels convenient to move are symmetrically arranged on the left side and the right side of the bottom of the base front and back; the hydraulic cylinder for driving height adjustment is arranged at the top of the base; the four first guide seats are arranged at the top of the base, a connecting frame is slidably connected between the tops of the first guide seats, and a mounting plate is hinged to the top of the connecting frame. A worker can push the handheld rod to drive the mounting plate and the parts above to move freely and easily, the electric drill does not need to be carried by hands to work, and manpower consumption is reduced.

Description

technical field [0001] The invention relates to a drilling device, in particular to a drilling device for tunnel excavation. Background technique [0002] At present, in the construction of engineering wiring bridges and pipelines, especially in the construction of tunnel cable installation projects, it is usually necessary to carry out a large number of drilling operations on the building walls to install detonators, explosives and other blasting supplies for pipelines and tunnel excavation. to place. Taking the company's high-tech tunnel construction as an example, due to the limitations of the special construction environment of the tunnel and the limitation of cross-operation of various sub-projects of the tunnel construction, the drilling operation cannot be fully mechanized, and most of the construction personnel directly operate the electric drill. The holes are drilled, but artificial drilling will naturally have the following disadvantages: [0003] 1. Accurate dr...
