A threaded rod 6 is rotatably connected to the top of the fixing frame 2, and the threaded rod 6 is threadedly connected to the sliding rod 8. By rotating the threaded rod 6, the sliding rod 8 drives the fixing plate 12 to move upward, and then the ultrasonic weld detector 10 moves upward, which is convenient for the staff to adjust the height of the ultrasonic weld detector 10 so that it can be applicable to scaffolding with different thicknesses. Two second connecting blocks 17 are fixed to the bottom outer wall of the fixing plate 12 by bolts. Connecting rods 5 are slidably connected to the interiors of the two second connecting blocks 17. One end of the connecting rod 5 is welded with a spring 15. Two first connecting blocks 16 are fixed to the top outer wall of the fixing plate 12 by bolts, and the spring 15 is fixed to the first connecting block 16. One end of the connecting rod 5 is fixed with a bolt with a pin 13. Two sockets 11 are opened on one side of the ultrasonic weld detector 10, and the pin 13 is inserted into the socket 11. By pulling the pull - ring 14 backward, the pin 13 moves outward and separates from the socket 11. At the same time, when the pin 13 moves, the connecting rod 5 slides along the second connecting block 17, and the spring 15 elongates. Then, the ultrasonic weld detector 10 can be directly separated from the fixing plate 12, and the disassembly of the ultrasonic weld detector 10 can be realized.

[0023] In the present utility model, it should be noted that a telescopic rod 9 is fixed to the outer wall of the top of the fixing frame 2 by bolts, and the telescopic rod 9 is fixed to the sliding rod 8.

A conveyor belt 1 is arranged inside the connecting frame 3. A speed reduction motor 4 is fixed to the outer wall of one side of the connecting frame 3. When it is necessary to detect the weld of the scaffold, place the scaffold with the detection surface facing up on the conveyor belt 1 and make the weld correspond to the detection head of the ultrasonic weld detector 10. The conveyor belt 1 drives the scaffold to move, so that the ultrasonic weld detector 10 detects the weld of the scaffold. One end of the output shaft of the speed reduction motor 4 is fixed to the connecting shaft on the conveyor belt 1. The speed reduction motor 4 rotates to make the conveyor belt 1 convey the scaffold to be detected. Reinforcing rods are fixed to both sides of the connecting frame 3 by bolts.

[0024] Working principle: When it is necessary to adjust the height of the ultrasonic weld detector 10, rotate the knob 7 to make the sliding rod 8 drive the fixing plate 12 to move upward, and then make the ultrasonic weld detector 10 move upward, which is convenient for the staff to adjust the height of the ultrasonic weld detector 10 so that it can be applicable to scaffolds of different thicknesses. When it is necessary to disassemble the ultrasonic weld detector 10, first pull the pull ring 14 backward to make the bolt pin 13 move outward and separate from the socket 11. At the same time, when the bolt pin 13 moves, the connecting rod 5 slides along the second connecting block 17 and the spring 15 elongates. Then, directly separate the ultrasonic weld detector 10 from the fixing plate 12.
