The support arm 22 is fixedly connected to the rotating cover 14 and is located on one side of the rotating cover 14. The axial flow fan 21 is fixedly connected to the support arm 22 and is located on the side of the support arm 22 away from the rotating cover 14. There are multiple groups of the rotating assembly 2, and multiple groups of the rotating assembly 2 are fixedly connected to the rotating cover 14 and are located around the rotating cover 14. The detection assembly 3 includes a torque sensor 31 and a controller 32. The controller 32 is fixedly connected to the housing 12 and is located inside the housing 12.

[0024] In this embodiment, the support assembly 1 includes a base 11, a housing 12, a support rod 13, and a rotary cover 14. The housing 12 is fixedly connected to the base 11 and is located on one side of the base 11. The base 11 is used to be fixed to the heightening device. The support rod 13 is fixedly connected to the housing 12 and is located on the side of the housing 12 away from the base 11. The rotary cover 14 is rotatably connected to the support rod 13 and is located on one side of the housing 12. The rotary cover 14 can rotate relative to the support rod 13. The rotation assembly 2 includes an axial flow fan 21 and an arm 22. The arm 22 is fixedly connected to the rotary cover 14 and is located on one side of the rotary cover 14. The axial flow fan 21 is fixedly connected to the arm 22 and is located on the side of the arm 22 away from the rotary cover 14. The arm 22 and the rotary cover 14 are connected to support the axial flow fan 21, so that when the axial flow fan 21 rotates, it can drive the rotary cover 14 to rotate relative to the support rod 13. There are multiple groups of the rotation assembly 2. Multiple groups of the rotation assembly 2 are fixedly connected to the rotary cover 14 and are located around the rotary cover 14.

After the torque is measured by the torque sensor 31, the torque is transmitted to the heightening device through the support rod 13, the housing 12, and the base 11. The controller 32 controls the rotation speed of the axial flow fan 21 according to the torque data. Finally, the data can be packaged and transmitted to the upper computer in real time, so that the heightening device can be conveniently and real-time measured. The generated torque is easy to control, the degree of automation is high, and the measurement accuracy is improved, thus solving the problem that the automation degree of the torsion angle detection of the current lifting heightening device is low and the test error is large, so it cannot meet the actual needs.

[0026] In this embodiment, the bearing 15 is arranged between the support rod 13 and the rotating cover 14, which can reduce the friction force when the rotating cover 14 rotates, thereby making the measurement of the torque more accurate. Then, a limit ring 16 is arranged on one side of the rotating cover 14 close to the bearing 15, so that the bearing 15 can be fixed more stably.

[0027] Furthermore, the base 11 includes a base body 111, a flange 112 and adjusting screws 113.

[0033] Furthermore, the support arm 22 includes a bracket 221 and a cover plate 222. The bracket 221 has a wire groove 224. The cover plate 222 is rotatably connected to the bracket 221 and is located on one side of the wire groove 224.

[0034] In this embodiment, the wire groove 224 on the bracket 221 can hold the wires of the axial flow fan 21, and the cover plate 222 protects the wires, thus preventing the wires from being interfered by the external environment and increasing their service life.

[0036] In this embodiment, the mounting seat 223 has a fan hole. The mounting seat 223 can be used to accurately install the axial flow fan, so that the axial flow fans 21 on all the support arms 22 are in the same position, making it easier to synchronously control the forces on all the axial flow fans 21.

[0037] Furthermore, the support assembly 1 further includes a dust-proof ring 17. The dust-proof ring 17 is fixedly connected to the outer shell 12 and is located on the side of the outer shell 12 close to the rotary cover 14.

[0038] In this embodiment, by providing the dust-proof ring 17, external dust and other impurities can be prevented from entering the bearing 15 through the gap between the rotating rod and the support rod 13, avoiding an increase in friction, and thus making the torque measurement more accurate.

The fan control module 321 can control the rotation speed of the axial flow fan 21 and transmit the rotation speed of the axial flow fan 21 to the data transmission module 324 for control. The data receiving module 322 is used to receive data from the torque sensor 31, and the electronic compass 323 is used to collect the current attitude information of the device. Then all the data is packaged and uploaded to the host computer through the data transmission module 324 for storage and processing.
