Coaxial reverse cable tunnel drilling device

Abstract

The invention discloses a coaxial reverse type cable tunnel drilling device and relates to the technical field of cable laying construction tools. It includes a chuck, a stepping motor for driving the chuck; the side wall of the chuck has at least three jaws evenly distributed in the circumferential direction; an arc top plate is installed at the end of each jaw; The lower end is connected to the output end of an electric push rod; the lower end of the electric push rod is equipped with a drive motor; the output end of the drive motor is connected to a coaxial reverse gearbox; the forward output end located on the upper part of the coaxial reverse gearbox A transmission shaft is connected; the reverse output end located at the lower part of the coaxial reverse gearbox is connected with a B tubular transmission shaft; the lower end of the spiral excavation bit is fixed to the upper end of the A transmission shaft; the upper end of the spiral road clearing bit is connected to the B tubular transmission The shaft is fixed; the helical direction of the helical road clearing bit is opposite to the helical direction of the helical tunneling bit. The utility model has the advantages of smart overall dexterity, small drilling resistance, strong drilling penetration and high efficiency.

Description

technical field [0001] The invention relates to the technical field of cable laying construction tools. Background technique [0002] The traditional pipeline laying method is to use manual excavation to bury the pipeline underground. Laying pipelines in this way is inefficient and seriously damages surface vegetation. There is also a non-excavation construction machine. The machine is to dig a larger square pit at both ends, put the machine in the pit at one end, first punch a hole with a puncher, and then use it to expand the hole. This kind of laying machine has limited laying distance, complicated construction and low efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a coaxial reverse cable tunnel drilling device for the above technical deficiencies, which is smart overall, has low drilling resistance, strong drilling penetration and high efficiency. [0004] The technical solution adopted by the...

Laying pipelines in this way is inefficient and seriously damages the vegetation on the ground

There is also a non-excavation construction machine. The machine is to dig a larger square pit at both ends, put the machine in the pit at one end, first punch a hole with a puncher, and then use it to expand the hole. The laying distance of this laying machine is limited, the construction is cumbersome, and the efficiency is low.
