Description

Building engineering detection device Technical Field The utility model relates to the technical field of building engineering detection, in particular to a building engineering detection device. Background In the field of quality detection of building engineering, wall hollowing detection is an important link, and the structural safety and the service life of a building are directly related. Currently, a dummy knocking method is commonly adopted in the industry to detect hollowing of the wall surface, and the principle is that dummy is used for knocking the wall surface, so that whether the hollowing phenomenon exists on the wall surface is judged according to the difference of the generated sounds. However, the conventional detection method has obvious defects that in the actual operation process, a detector needs to hold dummy by hand and repeatedly strike, especially when facing a large-area wall surface, the labor intensity is extremely high, the detection efficiency is extremely low, and a large amount of manpower and time cost are consumed. In summary, a novel building engineering detection device needs to be developed to realize efficient and accurate wall hollowing detection. Disclosure of utility model Aiming at the defects existing in the prior art, the utility model provides a building engineering detection device. In order to achieve the above object, the technical scheme of the present utility model is as follows: A building engineering detection device comprises a shell; The roller is rotationally arranged in the shell through the rotating shaft; The cam is fixed on the rotating shaft of the roller, and the outer wall of the cam consists of a continuous curved surface and a first step surface; The mounting sleeve is fixed on the outer wall of the shell, the top end of the mounting sleeve is provided with an adjusting component, and the bottom end of the mounting sleeve is provided with a sliding column with a soft hammer in a sliding penetrating way; The spool includes: The follower rod is fixed on the outer wall of the slide column, and the tail end of the follower rod extends to a rotating path of the outer wall of the cam and is used for driving the slide column to axially move along with the rotation of the cam; One end of the spring is connected with the top end of the sliding column, the other end of the spring is abutted against the adjusting component, and the follower rod is always attached to the outer wall of the cam through spring force; when the cam rotates, the follower rod drives the slide column to axially reciprocate to form knocking action. Preferably, when the follower rod transits from the step surface to the curved surface, the dummy head on the slide column extends to 0.2-0.5 cm outside the roller. Preferably, the outer wall of the sliding column is in clearance fit with the inner wall of the mounting sleeve. Preferably, the adjusting component comprises a screw rod threaded on the mounting sleeve, and a push plate contacted with the spring is fixed at the bottom end of the screw rod. Preferably, the telescopic handle is further provided with a plug bush with a polygonal inner wall at the end part of the telescopic handle, and a plug block matched with the plug bush is arranged on the outer wall of the shell and used for adjusting the relative angle between the telescopic handle and the sliding column in a multidirectional manner. Preferably, the insert blocks lock the relative positions of the shell and the telescopic handle through bolt pieces. Compared with the prior art, the utility model has the beneficial effects that: 1. Through the dummy heads arranged on the slide column and the continuous rotation driving mechanism of the rollers, the soft hammer head can realize continuous and periodic knocking actions on the wall surface in the running process of the rollers. When the roller rolls along the wall at a constant speed, the slide column drives the dummy head to reciprocate under the action of the cam and the follower rod, and a worker generates echo through the impact between the end face of the hammer head and the wall to judge whether the wall is empty or not. The design not only greatly reduces the labor intensity of manual reciprocating knocking, but also remarkably improves the detection efficiency of the large-area wall surface. 2.

The adjusting component adopts a threaded transmission structure, and a detector can change the pretightening force of the spring through the screw rod according to different characteristics of wall materials (such as a plastering layer, a ceramic tile surface, a concrete base layer and the like). When the compression amount of the spring is increased, the dummy head obtains larger impact kinetic energy, and otherwise, the impact force is reduced. Drawings The
