Abstract
Description
Technical Field
[0001] This utility model belongs to the field of testing equipment technology, specifically relating to a crack detection device. Background Technology
[0002] Existing crack detection equipment requires adjusting the distance of the ultrasonic testing end and fixing the testing end for detection. This requires multiple people to hold the equipment in place, and the excessive height makes it inconvenient to adjust the position of the testing end. The "Crack Detection Device" disclosed in application number "CN202322463857.4" is an increasingly mature technology. It adjusts the detection height by moving the crack detector body on a column and using an electric cylinder to adjust the angle between the column and the support legs to adjust the verticality of the column, which is beneficial for convenient detection of wall cracks. However, this device still has the following drawbacks: during each detection process, the end of the testing device needs to be glued to the marked area with coupling agent. The staff needs to manually straighten the testing end of the device to detect the concrete surface, which is inconvenient to operate. In addition, the wiring and equipment are not easy to store after use. Utility Model Content
[0003] The purpose of this utility model is to provide a crack detection device, which aims to solve the problems in the prior art where the end of the detection device needs to be glued to the marked area with a coupling agent during each detection process, and the staff needs to manually straighten the detection end of the device to detect the concrete surface, which is inconvenient to operate, and the wiring and equipment are not easy to store after use.
[0004] To achieve the above objectives, this utility model provides the following technical solution: It includes an ultrasonic detector, with power sockets on both sides of the top of the ultrasonic detector. A connecting wire is installed inside the power socket, and an ultrasonic detection probe is installed at one end of the connecting wire. An inner shell is provided on the outer wall of the ultrasonic detection probe, and an outer shell is provided on the outer wall of the inner shell. Vent holes are symmetrically opened on one side of the outer shell, and an air extraction chamber is opened in the middle of the outer shell. The vent holes and the air extraction chamber are sealed and connected. A miniature air extraction pump is embedded on one side of the inner wall of the air extraction chamber, and an electromagnetic vent valve is provided on the other side of the outer shell.
[0005] In one embodiment of the crack detection device of this utility model, a first rubber ring is provided on one side of the inner shell, and a second rubber ring is provided on one side of the outer shell.
[0006] In this solution, the connectors of the two connecting wires are inserted into the power socket. At this time, the ultrasonic detection probe is pressed against the wall, the first rubber ring and the second rubber ring are attached to the wall, and the miniature air pump draws air from the air chamber. Suction is generated at the vent, creating a vacuum in the space between the inner and outer shells, which adsorbs and fixes the ultrasonic detection probe to the wall.
[0007] In one embodiment of the crack detection device of this utility model, a filter cylinder is threadedly connected to one end of the inner wall of the vent hole, and a filter element is provided on one side of the inner wall of the filter cylinder.
[0008] In this solution, during the suction process, the dust sucked into the wall surface is filtered by the filter element inside the filter cartridge.
[0009] In one embodiment of the crack detection device of this utility model, the top of the ultrasonic detector is equipped with a wireless signal transmitter, and the top of the miniature air pump and the electromagnetic vent valve are equipped with signal receivers.
[0010] In this solution, during use, the ultrasonic detector emits a wireless signal, and the signal receiver operates after receiving the signal. When the ultrasonic detection probe is released, the miniature air pump stops working, the electromagnetic vent valve opens to release air, and the ultrasonic detection probe's adsorption state is canceled.
[0011] In one embodiment of the crack detection device of this utility model, the ultrasonic detector is provided with a frame-shaped support leg on one side, and a limiting frame is provided on one side of the frame-shaped support leg.
[0012] In this solution, the ultrasonic detector is placed on the wall and supported by frame-type support legs during use. After use, the ultrasonic detector probe can be stored in the limiting frame.
[0013] In one embodiment of the crack detection device of this utility model, the other side of the frame-shaped support leg is hinged to a limiting frame and fixedly connected to a limiting seat. A limiting ring is hinged to one side of the bottom of the limiting seat, and a limiting groove is opened on the other side of the limiting seat. One end of the limiting ring is engaged and connected in the limiting groove.
[0014] In this solution, the connecting wire can be wound around the limiting ring, and the limiting ring can be engaged with the limiting groove to store the connecting wire.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1) By attaching the first and second rubber rings to the wall, the micro air pump draws air from the air extraction chamber, and the air vent generates suction, creating a vacuum in the space between the inner and outer shells, which adsorbs and fixes the ultrasonic detection probe to the wall, making it easy to quickly fix the ultrasonic detection probe in the designated position for crack detection.
[0017] 2) By storing the ultrasonic testing probe inside the limiting frame, the connecting wire can be wound around the limiting ring, and the limiting ring can be engaged with the limiting groove to store the connecting wire. Attached Figure Description
