Description

Technical Field

[0001] The utility model belongs to the technical field of construction engineering, and in particular relates to an intelligent floor defect detection device. Background Art

[0002] "Hollowing" in house construction refers to the phenomenon that occurs due to loose adhesion and bonding between floors, walls and structural layers. Hollowing is caused by the presence of air in the original masonry and the powder ash layer, and a thumping sound will be heard when struck with a hollowing hammer. Hollowing detection in house construction is an important inspection item. If there are hollows on the floor of a house building, it is likely to affect the quality of subsequent decoration. In the prior art, the hollowing detection of house construction quality is that the inspector uses a hollowing hammer to continuously strike the floor and listen to the sound to distinguish. During the inspection process, the inspector needs to squat or bend over continuously and conduct large-scale knocking inspections on the floor in turn. This method is not only inefficient, but also may cause omissions due to the inspector's experience, and may also cause physical discomfort to the inspector.

[0014] The beneficial effects of the present invention are:

[0015] 1) The first gear and the knocking rod are fixedly connected on the rotating shaft at the same time, and are installed at the front end of the support plate through the bearing seat. The first motor drives the toothless gear to rotate, and the toothed part of the toothless gear meshes with the first gear. The knocking rod is rotated through the transmission of the rotating shaft, and the knocking ball at the far end of the knocking rod moves away from the floor. Then, when the toothless gear rotates to the toothless part and aligns with the first gear, the knocking ball falls due to gravity, and the floor is knocked; the toothless gear rotates continuously, and then forms an intermittent and regular driving of the knocking hammer to knock on the floor, so as to realize hollowing detection. The structure of the knocking is simple; because the knocking hammer falls due to gravity, it forms a rapid impact and a powerful blow when it contacts the floor, and the knocking effect is significant, thereby improving the detection quality;

[0016] 2) The spring pushes the first roller support frame downward, causing the first roller to abut against the floor. When the floor is uneven, the first roller support frame either moves upward to compress the spring or moves downward to reduce the compression of the spring, thereby causing the vertical rod to move vertically. The displacement sensor monitors the displacement of the vertical rod, thereby recording the flatness and transmitting the displacement change information of the vertical rod to the controller;

[0017] 3) The obstacle avoidance sensor monitors in real time whether there is an obstacle at the front end of the support plate and immediately transmits the information to the controller. The controller then controls the steering of the front roller and the forward, backward or stop of the rear roller through the second motor and the third motor, realizing intelligent detection of floor hollowing.
