Description
Technical Field
The invention relates to the technical field of municipal road detection, in particular to a concrete drilling and core-drilling machine drill rod for municipal road detection.
Background
In municipal detection, in order to prevent the situation that the material is reduced due to the fact that the road is stolen during construction, the road surface needs to be detected after the road is finished, some key data need to be sampled, and meanwhile, in order to measure the thickness of concrete road pouring, the road needs to be drilled and cored, so that the drilling and core-taking machine is derived and is widely applied to municipal detection centers in various places.
The main part of core machine is exactly the drilling rod to the drilling, traditional drilling rod is the integral type barrel that the bottom has the grinding head, and peripheral and inside diameter about is the same, consequently when drilling, the inboard and the outside of drilling rod all can contact with the concrete, when the drilling rod is rotatory, will rub each other with the concrete and produce the heat, also can cause wearing and tearing to the drilling rod simultaneously, and at the drilling in-process, need pour into a mould cold water on the drilling rod always and be used for cooling the drill bit, but traditional drilling rod is when the cooling, cold water can't reach the contact surface of drilling rod inboard and concrete, make the cooling effect descend, the wearing and tearing of drill bit have been aggravated.
In order to solve the problems, the inventor provides the concrete drilling and core-drilling machine drill rod for detecting the municipal roads, when the holes are drilled, concrete cannot contact with the inner wall and the outer wall of the cylinder and the threaded rod, so that the contact area between the drill rod and the concrete is greatly reduced, heat generated when the drill rod and the concrete are rubbed is reduced, the abrasion speed of the drill rod is reduced, cooling water can better enter between the drill rod and the concrete, the cooling effect is improved, and the drilling efficiency is improved.
