Description

Technical Field

[0001] The utility model belongs to the field of water cracks, and in particular relates to a water crack detection device. Background Art

[0002] Crack detection devices are instruments used to accurately detect the width and depth of cracks in bridges, tunnels, buildings, concrete pavements, metal surfaces, etc. In the construction industry, some cracks will continuously generate and expand new cracks under the influence of loads or external physical and chemical factors, forming through cracks. The above cracks will directly destroy the integrity of the structure, causing concrete carbonization, peeling of the protective layer, corrosion of steel bars, and greatly reducing the bearing capacity. In severe cases, even collapse accidents will occur, affecting normal use. At present, the use of crack detection equipment relies more on electrical component sensing, which makes the cost of use and subsequent maintenance and repair relatively high. At the same time, before crack detection, it usually takes a certain amount of time to calibrate online, which undoubtedly reduces the efficiency of detection. Therefore, a device with a simple structure and intuitive detection results is needed for crack detection. Utility Model Content

During the loosening of the rope body, the lead block gradually penetrates into the crack, and the smooth surface of the lead block will not be hooked by the unevenness in the crack. During the continuous advancement of the lead block into the crack, the depth of the crack can be read by scale 1. Of course, different positions of the crack have different depths. By rotating the rocker, the screw rod 1 can be driven to rotate, so that the threaded block 1 drives the rod body 1, the rod body 2, the bracket and the lead block to move, and move to the crack. Another position of the crack is located at the other end, and the depth of different positions in the crack is carefully measured.

When the lead block gradually moves from one side of the crack to the other side of the crack, the crack width can be measured and detected. At the same time, the setting of the rod body 1 and the rod body 2 can also improve the flexibility of the position of the bracket and the lead block, further reducing the inconvenience of moving and adjusting the device. At the same time, the length of the crack can be easily detected through the scale 3.

[0006] The present invention is further configured such that one end of the connecting rod 1 passes through one side of the bracket, a rotary motor is fixedly mounted on one side of the bracket, and an output end of the rotary motor is fixedly sleeved with the connecting rod 1 through a coupling.

[0007] Adopting the above technical solution: the operation of the rotating motor will drive the connecting rod 1 to rotate.
