Description

Technical Field

[0001] The utility model relates to the technical field of house detection, in particular to a comprehensive crack testing device for house detection. Background Art

[0002] It is inevitable that cracks will appear in the house during use, and of course a certain degree of cracks is acceptable. House cracks can be mainly divided into two categories: structural cracks and non-structural cracks. Structural cracks are cracks caused by various static and dynamic loads directly applied to the house during use. The structural bearing capacity is insufficient and the stress reaches the limit. This type of crack is relatively dangerous and requires timely house safety appraisal, while providing scientific and reliable data for later repairs. Non-structural cracks are cracks caused by indirect effects such as temperature changes, shrinkage, and uneven settlement during the use of the house, and the deformation of the house structure is constrained. Although this type of crack has little effect on the structural bearing capacity of the house, the causes of the cracks are complex and the impact on the structure is also quite different. Although non-structural cracks have little effect on the structure of the house, when large cracks appear, for safety reasons, a house safety appraisal agency should be entrusted to conduct inspections to ensure the usability of the house.

[0003] A comprehensive crack testing device for house detection is disclosed in the Chinese utility model patent application disclosure CN220207459U. Although the comprehensive crack testing device for house detection has the effects of improving detection stability and facilitating storage and transportation by adjusting the coordination of the base, the support frame, the connecting clamp rod, the first spring, and the fixing plate, some cracks in the house are on the inner top surface. Since the angle of the detection instrument cannot be adjusted, the testing device is not convenient for testing cracks on the inner top surface of the house, and has the disadvantage of poor applicability.

[0015] 1. A comprehensive crack testing device for house detection, through the arrangement of a moving block, a sleeve column, a telescopic rod, and a rotating block, enables the comprehensive crack testing device for house detection to have the effect of facilitating detection of different positions in a house. When in use, the fixed block is moved to a corresponding position in the house, so that the detection instrument is close to the crack on the wall, and the crack is detected by the detection instrument. During the detection process, the operation of the first servo motor and the second servo motor is controlled according to the direction of the crack on the wall.

During the sliding process, the limit block on the outer surface of the telescopic rod slides in the limit groove on the inner surface of the sleeve column, which plays a role of limiting. By making the telescopic rod slide in the sleeve column, the height of the detection instrument is changed, which plays a role of adjusting the height, and thus it is convenient to detect along the direction of the cracks on the wall. When detecting cracks on the top surface of the house, the output end of the third servo motor is controlled to rotate, and the rotating column is driven to rotate by the third servo motor, so that the rotating block fixedly connected to the inner side of the rotating column rotates, and the detection instrument is driven to rotate when the rotating block rotates, thereby changing the detection angle of the detection instrument, facilitating the detection of cracks on the inner top surface of the house, and achieving the purpose of improving the applicability of the testing device.
