Description

Technical Field

[0001] This utility model relates to the field of ultrasonic point positioning technology, and in particular to an ultrasonic point positioning device for concrete used in building inspection. Background Technology

[0002] Concrete is a core material for modern high-rise buildings, bridges, tunnels, and dams. However, during construction and aging, it is prone to defects such as voids and air bubbles, as well as stress-induced cracks. If these internal defects are not detected in time, they may lead to a decrease in structural load-bearing capacity or even collapse, directly threatening life and property safety. Ultrasonic point positioning equipment plays a crucial role in ensuring the quality of concrete in construction, which is essential for personnel safety. It is used to detect voids and air bubbles in concrete, facilitating subsequent maintenance and repair of buildings. Concrete ultrasonic point positioning equipment for construction inspection is mostly used in scenarios where non-destructive testing is conducted to pinpoint the exact location of internal defects in concrete.

[0003] When it is necessary to pinpoint the exact location of internal defects and damage in concrete, ultrasonic point positioning equipment for building inspection is required. Existing such equipment often involves manually holding the probe against the concrete surface, which is time-consuming and labor-intensive. Furthermore, manual holding can lead to inconsistent spacing between test points and incomplete correspondence between test points on the test surface, affecting test accuracy and interfering with data processing. This results in longer maintenance cycles, increased production costs, decreased concrete quality within buildings, reduced lifespan, and numerous safety hazards. Utility Model Content

[0041] Working principle: The folding rod 1 has fixed blocks 3 at both ends, which serve as bases to stabilize the front-end fixed limiting post 5. A driving rod 7 is provided on the outer wall of the limiting post 5 to limit its angle of movement. A pin 6 is slidably connected to the inner walls of the limiting post 5 and the driving rod 7. The pin 6 connects the limiting post 5 and the driving rod 7, allowing the driving rod 7 to rotate. The limiting groove 12 on the inner wall of the driving rod 7 allows the folding handle 9 to be pushed out after folding, causing one end of the driving rod 7 to extend. However, this extension is blocked by the fixed blocks 3, preventing further movement. When unfolded, it can be used to fix the folded handle 9 after folding. The telescopic rod 8 at the front end of the drive rod 7 acts on the drive hole 10 and drive rod 7 opened on the inner wall of the folded handle 9.

The positioning protrusion 4 is inserted into the key groove 11 on the inner wall of the folded handle 9. Rotating the folded handle 9 can achieve the locking effect.

[0042] The groove 202 on the inner wall of the crossbar 201 serves as a guide rail for the sliding wheel 203. The inner wall of the sliding wheel 203 is fixedly connected to the axle 204. The outer shell 205 fixedly connected to the front end of the axle 204 allows for left and right movement. At the same time, the snap fastener 20 can drive the probe 18 to move left and right to achieve precise lateral positioning. The sliding shell 206 on the left side of the crossbar 201 is connected to the motor 207 fixedly connected to its inner wall. When the motor 207 is started, it drives the first bevel gear 208, which in turn drives the meshing second bevel gear 209, transmitting power to the linkage rod 210 fixedly connected to the inner wall. Finally, the linkage rod 210 drives the pulley 211 fixedly connected to the outer wall. The outer wall of the pulley 211 is slidably connected to the folding rod 1. The sliding shell 206 drives the entire crossbar 201 to move back and forth to achieve precise vertical positioning. The combination of the two can drive the probe 18 to move and achieve precise positioning in all directions.
