Perforating device for building detection

Abstract

The invention discloses a perforating device for building detection. The perforating device comprises a directional holding mechanism and a drilling dustproof structure; the drilling dustproof structure is mounted in the directional holding mechanism; a motor is installed on a fixed plate of the drilling dustproof structure in a matched mode through bolts; a set of through holes are formed in the fixed plate in the circumferential direction; one end of each positioning rod is in sliding fit with the corresponding through hole, and the other end of each positioning rod is hinged to a movable compression plate through pin shafts; each positioning rod is sleeved with a compression spring; and the two ends of each compression spring abut against the fixed plate and the movable compression plate respectively. According to the scheme, the supporting frame of a table structure is supported on the wall, the drilling angle is determined by a positioning barrel and locked by a positioning screw, the compression plate presses the wall under the action of the compression springs, the compression springs and the pin shafts are matched with each other so that the compression plate can be tightly attached to the wall all the time during drilling, the contact area can be increased, and the drilling stability can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of building inspection, in particular to a punching device for building inspection. Background technique [0002] The major of architectural engineering is mainly responsible for the teaching and management of the direction of architectural engineering for civil engineering majors. It mainly cultivates and masters the basic theories and basic knowledge of engineering mechanics, soil mechanics, surveying, building architecture and structural engineering. All kinds of buildings and engineering facilities based on material technology; [0003] When inspecting construction projects, it is necessary to drill holes for sampling and observation. When drilling holes, they usually use straight drills to drill holes. When drilling oblique holes on the wall, it is not easy to control the position of the holes, and the location of the holes cannot be accurately determined. Position and hold.

Problems solved by technology

[0003] When inspecting construction projects, it is necessary to drill holes for sampling and observation. When drilling holes, they usually use straight drills to drill holes. When drilling oblique holes on the wall, it is not easy to control the position of the holes, and the location of the holes cannot be accurately determined. locate and hold

In addition, dust will be generated during drilling, which will not only pollute the working surface, but also cause gravel to splash, which is less safe and unsafe to operate, and also affects the positioning and maintenance of the drilling position and angle.
