Dual-purpose adjustable core drilling machine

Abstract

The invention discloses a dual-purpose adjustable core drilling machine. The dual-purpose adjustable core drilling machine comprises a bottom plate, wherein a base is fixed at one head end of the bottom plate, an uprights is vertically arranged on the base, the dual-purpose adjustable core drilling machine further comprises a slideway capable of sleeving the upright, the slideway is provided witha slideway gear in the length direction, a slide block is movably connected to the slideway, a motor and an advance and retreat operation handle are arranged on the slide block, a drill bit is connected to the bottom of the motor, the dual-purpose adjustable core drilling machine further comprises a sleeve capable of sleeving the upright, and the head end of the sleeve is vertically connected witha sleeve cross beam capable of sleeving into the slideway. After being fixed on the ground surface, the core drilling machine drills the core of the ground surface as well as the core of a tunnel, one machine has multiple purposes, and the core drilling machine further has the advantages that the motor does not need to be taken down when the core is drilled, the core drilling efficiency is high,no expansion bolt is needed, the core drilling machine is convenient to transport, and the uneven working ground surface does not cause vibration of the drilling machine either.

Description

technical field [0001] The invention relates to a coring machine, in particular to a dual-purpose adjustable coring machine. Background technique [0002] With the rapid growth of the national economy, my country's highway industry has been greatly developed, the highway network has begun to take shape, and the road network of various grades is constantly increasing. The large-scale construction of highways and tunnels makes it more and more important to detect their construction quality. When testing pavement and tunnel lining, cores should be taken from pavement and tunnels according to national regulations, and how to quickly and efficiently take out core samples has become an urgent requirement for testing. [0003] The biggest problem of the existing coring machine is that when drilling a core sample at a specific position, it is necessary to drag the drilling rig as a whole to adjust the position, and it is impossible to adjust the position of the drilling rig when th...

AI Technical Summary

Problems solved by technology

[0005] (1) When the drilling depth is greater than one time (about 40cm), the drill bit needs to be taken out from the drilling hole, and the motor must not be lifted out, which increases the workload and reduces the work efficiency

[0006] (2) When the equipment is working, the unevenness of the ground often causes the vibration of the drilling rig

[0007] (3) Due to the small area of ​​the base of the fixed slideway, expansion bolts should be used to fix the base on the ground before coring, and the preparatory work of drilling expansion bolt holes, fixing the coring machine and pulling out the expansion after drilling is completed. Aftermath work such as bolts takes too much time

[0008] (4) The size of the base is small, the force on the expansion bolt is large, it is easy to loosen, and the rig shakes violently

It is even more difficult to anchor on asphalt roads, and it is impossible to take coring
