[0028] Specifically, in this embodiment, the load-bearing assembly 18 includes a torsion spring adjustment assembly 12 and a torsion spring fixing assembly 23; the torsion spring fixing assembly 23 includes a driving wheel 19, a torsion spring fixing frame 20, a torsion spring 21, and a torsion spring shaft 24.

The tension adjustment shaft 27 connects two symmetrically installed mounting links 28.

[0032] Specifically, in this embodiment, the track 31 is made of rubber, and the anti-skew wheel 13, drive wheel 19, first support plate 32, second support plate 33, and load-bearing roller 29 are made of insulating materials. If the relevant wire rope is made of conductive material and is not insulated, it will generate eddy currents under the action of the detection magnetic field. These additional eddy currents will interfere with the detection and analysis of the wire rope eddy current signal, resulting in inaccurate detection results and may even mask the actual fracture information of the wire rope. Therefore, designing the relevant materials of the mobile detector to be insulating materials not only reduces the heat and loss generated by electromagnetic induction, avoids adverse effects on the performance and life of the detection equipment, but also helps maintain the stability of the equipment operation and ensures the smooth operation of the detection work.

In the event of an accident, the anti-fall paddle will prevent falling by cooperating with relevant components. The anti-fall mounting seat is used to fix the anti-fall paddle, provide it with an installation position and support, and connect the entire anti-fall device to the fixed frame so that the anti-fall device can work stably. Connecting the anti-fall mounting seat and the anti-fall paddle allows the anti-fall paddle to move within a certain range, while ensuring the connection strength between the two, so that the anti-fall paddle can play its role accurately when needed. The anti-fall spring plays a role of buffering and resetting. When the anti-fall paddle is subjected to external force, the spring will deform, absorb part of the impact force, and after the impact force disappears, help the anti-fall paddle return to its original position so that it can work normally next time.

[0035] Specifically, in this embodiment, the encoder of motor 38 is connected to a micro-electromagnetic eddy current array, a MEMS fiber Bragg grating (FBG), and a microwave positioning beacon. This connection enables comprehensive information on the status of the mobile motor. By integrating and analyzing defect information detected by the micro-electromagnetic eddy current array, strain and temperature data sensed by the MEMS fiber Bragg grating (FBG), and location information provided by the microwave positioning beacon, the operating status of the wire rope intelligent diagnosis system can be more comprehensively and accurately analyzed. This ensures that potential wire rope faults are not only detected but also that more precise equipment maintenance plans are implemented, thereby improving the accuracy of fault diagnosis.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
