Portable drilling machine applied to tunnel structure detection

Abstract

The invention relates to a portable drilling machine for tunnel structure detection, which includes a motor, a drill rod and a handle. A driving chamber is arranged above the motor, and a lifting mechanism and a cleaning mechanism are arranged in the driving chamber. The lifting mechanism includes a first motor , a first bevel gear, a lifting plate, a lifting rod and two lifting units. The cleaning mechanism includes a retractable component and a cleaning component. The portable drilling machine used for tunnel structure detection drives the drilling rod up and down through the lifting mechanism, so that the drilling rod It can automatically extend into or out of the ground, avoiding the bending operation of the staff and manually taking out the drill pipe after work, which reduces labor intensity; in addition, after the drill pipe is taken out from the ground, the dirt on the drill pipe is cleaned by the cleaning mechanism. Automatic cleaning of objects, saving time and effort, and bringing convenience to the staff.

Description

technical field [0001] The invention relates to the field of detection equipment, in particular to a portable drilling machine for tunnel structure detection. Background technique [0002] Drilling machine refers to the general term for machinery and equipment that leaves cylindrical holes or holes on the target by means of rotary cutting or rotary extrusion using tools that are harder and sharper than the target. Also known as drilling rig, punching machine, drilling machine, through hole machine, etc. Some of the existing portable drilling machines can be used to detect the tunnel structure and provide guarantee for the safe passage of the tunnel. [0003] Yet existing portable drilling machine still has some deficiencies in use, as: existing portable drilling machine, is to hold the fuselage by one or two people, when drilling rod rotates downward, needs people to drill rod Keep pressing down, and at the same time, you need to bend down to cooperate with the drill pipe ...

Problems solved by technology

[0003] Yet existing portable drilling machine still has some deficiencies in use, as: existing portable drilling machine, is to hold the fuselage by one or two people, when drilling rod rotates downward, needs people to drill rod Keep pressing down, and at the same time, you need to bend down to cooperate with the drill pipe to drill deep into the surface. After the drilling is completed, you need to take out the drill pipe forcefully. Long-term operation consumes a lot of energy; Some debris such as sludge is attached, and the staff need to clean the dirt manually, which is time-consuming and laborious, and brings inconvenience to the staff
