However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] As attached Figure 1 -Appendix Figure 5 As shown, this utility model provides a technical solution: a sound wave transmission method detection lifting device, including an installation device 1, an adapter mechanism 7 is assembled at the top of the installation device 1, and a protection mechanism 8 is assembled at the top of the installation device 1.

[0026] The adapter mechanism 7 includes a first column 71, a first through column 72 slidably connected to the outer wall of the first column 71, a first sphere 73 fixedly connected to the inside of the first through column 72, a first ball groove 74 formed on the outer wall of the first column 71, a small ball groove 75 formed inside the first ball groove 74, a slider 76 fixedly connected to the inside of the first through column 72, a sliding groove 77 formed on the side end of the first column 71, a connecting column 78 fixedly connected to the side end of the first through column 72, a circular plate 79 fixedly connected to the side end of the connecting column 78, an arc plate 710 fixedly connected to the side end of the circular plate 79, a plate 711 fixedly connected to the side end of the arc plate 710, and a rotating wheel 712 rotatably connected to the side end of the plate 711.

[0027] The overall effect of Embodiment 1 is as follows: the relevant components can improve the adaptability of the cable drum to cables of different sizes through column transmission. During the winding process, the movement trajectory of the cable inside the cable drum groove can be standardized. In this mechanical transmission method, the adapter device adapts to cables of different sizes during winding, thereby improving the accuracy of the test results.

[0028] Example 2, as Figure 1-5 As shown, a support frame 2 is fixedly connected to the top of the mounting device 1, a motor 3 is installed at the top of the support frame 2, a rotating drum 4 is fixedly connected to the output shaft of the motor 3, a groove 9 is provided on the outer side of the rotating drum 4, a first support plate 5 is fixedly connected to the top of the mounting device 1, a limit device 6 is provided at the top of the first support plate 5, the protection mechanism 8 includes a second through column 82, a second column 81 is slidably connected inside the second through column 82, a second ball groove 84 is provided on the outer wall of the second column 81, a second ball 83 is fixedly connected inside the second through column 82, the second column 81 is elastically slidably connected to the outer wall of the second through column 82 by a spring, a second support plate 85 is fixedly connected to the side end of the second column 81, a roller 86 is rotatably connected inside the second support plate 85, and the rotating drum 4 is rotatably connected to the side end of the first support plate 5 through the output shaft of the motor 3.

[0029] The effect achieved by the entire embodiment 2 is that the cable is wound around the outer wall of the roller 86, the roller 86 is squeezed by external force, and the second column 81 slides inside the second through column 82, which reduces the wear on the cable and improves the overall performance and reliability of the equipment.

[0030] The working principle of the entire equipment is as follows: Equipment inspection phase: Before starting the inspection, ensure that all parts of the device are in normal working condition.

[0031] During the winding stage: The worker connects the installation device 1 to the external support structure. At this time, the worker starts the motor 3, which drives the rotating drum 4 to rotate at the side of the first support plate 5. At this time, due to the different sizes of the cable, it shakes inside the groove 9 due to external factors during winding. At this time, the cable rolls on the outer wall of the rotating wheel 712 while squeezing the arc plate 710 and the circular plate 79. At this time, the circular plate 79 drives the connecting column 78, the first through column 72 and the first ball 73 to slide on the outer wall of the first column 71. Due to the first ball 73 connected to the first through column 72, 3. The first ball groove 74 and the small ball groove 75 opened on the outer wall of the first column 71 make the cable more standardized when winding inside the groove 9. At this time, the slider 76 slides elastically inside the groove 77. The arc plate 710 and the circular plate 79 are used to adapt to the size and specifications of the cable, so that the rotating wheel 712 fits tightly against the outer wall of the cable. When the cable is winding, it squeezes the roller 86, so that the roller 86 drives the second support plate 85 and the second column 81 to slide elastically inside the second through column 82. At this time, due to the second ball 83 and the second ball groove 84, the friction between the two is increased.

[0032] Connecting the transducer to the instrument: Connect the transducer to the ultrasonic testing instrument or other data acquisition system via a dedicated cable. After the connection is complete, transmit ultrasonic waves and receive signals.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
