Problems solved by technology

[0003] The installation hole position of the contact line installation frame of the subway tunnel and the tunnel top are as high as about 5m. Before the tunnel drilling machine was developed and used, the drilling work of these holes had workers on the scaffold manually holding the impact drill. Drilling is labor-intensive, work efficiency is low, and quality control is difficult

Embodiment Construction

[0031] The tunnel drilling machine includes the following parts: the base part, which is composed of steel structure and steel wheels, implements the operation of the tunnel drilling machine on the track. At the same time, it supports the weight of the entire drilling machine; the frame part is made of high-strength aluminum alloy profiles to effectively reduce its own weight. It is easy to assemble and disassemble, and the entire impact height can be adjusted arbitrarily according to the actual use requirements; for the electric control part, the electric control adopts two control modes, continuous punching and inching punching. At the same time, it is equipped with a socket for lighting or other purposes during operation; the tunnel drilling machine is equipped with a vacuum device, which is installed near the drill bit. When drilling, the dust drilled by the drill bit can be effectively sucked by the vacuum device. absorb. It can effectively improve the working environmen...

Abstract

The invention discloses a tunnel drilling machine, relating to a drilling device at the top of a tunnel. The tunnel drilling machine mainly comprises a base, a frame, a transverse guide mechanism, a longitudinal feed mechanism, a drilling rod and a power mechanism for driving the drilling rod, wherein the longitudinal feed mechanism is arranged on the frame through the transverse guide mechanism, the drilling rod and the power mechanism are arranged at the top of the longitudinal feed mechanism, and the drilling rod can move in the vertical direction through the longitudinal feed mechanism. The tunnel drilling machine is lighter in weight and convenient to mount and detach in the tunnel, can be arranged on a track at any time for construction, and can be evacuated from a track area at any time so as to make a room for the track to facilitate the construction of other construction parties. During drilling, the horizontal part is connected with the vertical part through a gear, thus the drilling precision is higher.

Description

[0001] technical field [0002] The invention belongs to the drilling equipment for the top of the tunnel, and mainly relates to a tunnel drilling machine which is convenient for movement and positioning. Background technique [0003] The installation hole position of the contact line installation frame of the subway tunnel and the tunnel top are as high as about 5m. Before the tunnel drilling machine was developed and used, the drilling work of these holes had workers on the scaffold manually holding the impact drill. Carry out punching, labor intensity is big, work efficiency is low, and quality control is difficult. Contents of the invention [0004] The purpose of the present invention is to solve the deficiencies of the above-mentioned technical problems, and provide a tunnel drilling machine, which can significantly improve the work efficiency of tunnel drilling, ensure the quality of drilling, and greatly reduce the labor intensity of workers during construction in ...
