Problems solved by technology

[0002] 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

[0030] The tunnel puncher includes the following parts: the base part is composed of steel structure and steel wheels, and the tunnel puncher runs on the track. At the same time, it supports the weight of the entire punching 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 actual use requirements; the electric control part, the electric control adopts two control modes, continuous punching mode and inching punching mode. 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 dust suction device, which is installed near the drill bit. When drilling holes, the dust drilled by the drill bit can be effectively sucked by the dust device absorb. It can effectively improve the working environment and protect the health of worker...

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

Technical field [0001] The invention belongs to a drilling device used for the top of a tunnel, and mainly relates to a tunnel drilling machine that is convenient for movement and positioning. Background technique [0002] The installation hole position of the installation frame of the subway tunnel contact line and the tunnel top are as large as about 5M. Before the tunnel drilling machine is developed and used, the drilling of these holes requires workers to manually hold the percussion drill on the scaffold. Punching requires high labor intensity, low work efficiency and difficulty in quality control. Summary of the invention [0003] The purpose of the present invention is to solve the deficiencies of the above technical problems and provide a tunnel drilling machine, which enables tunnel drilling to significantly improve work efficiency and ensure the quality of drilling. Construction in the tunnel can greatly reduce the labor intensity of workers. [0004] The technical solut...
