The rear ends of the left side plate 6 and the right side plate 7 are provided with a rear cable isolation assembly 30, which has the same isolation and arrangement effect on the rear cable 20.

[0039] Working principle: first, power on the five electromagnetic clutches, then the electromagnetic clutch body 12 is attracted, when the electromagnetic clutch body 11 and the main body are attracted, the large rubber wheel 9 rotates with the hollow main shaft 1, when the electromagnetic clutch body 11 and the main body are separated, even if the hollow main shaft 1 rotates, the large rubber wheel 9 does not rotate, ensuring that all the large rubber wheels 9 are successfully connected with the hollow main shaft 1. Then, start the driving motor 31 and all the reduction motors 27 at the same time, control the forward or reverse rotation of the driving motor 31 and the reduction motor 27 according to the cable winding and unwinding requirements.

[0040] In the process of cable winding and unwinding, when the whole cable winding and unwinding operation is performed, first, the five electromagnetic clutches are powered on. After being powered on, the electromagnetic clutch part 11 drives the large rubber wheel 9 to be attracted to the electromagnetic clutch main body 12, so that all the large rubber wheels 9 are relatively fixedly connected with the hollow main shaft 1. Then, the driving motor 31 and all the speed reducer motors 27 are powered on, the driving motor 31 outputs power to the hollow main shaft 1 through the speed reducer 2, and the hollow main shaft 1 starts to rotate. Since the large rubber wheel 9 is connected with the hollow main shaft 1, all the large rubber wheels 9 rotate synchronously with the hollow main shaft 1. At the same time, the speed reducer motor 27 drives the compression roller shaft 23 to rotate, and the compression roller shaft 23 drives the small rubber wheel 21 to rotate. The synchronous rotation of the large rubber wheel 9 and the small rubber wheel 21 generates friction force on the cable 20. By controlling the forward rotation or reverse rotation of the driving motor 31 and the speed reducer motor 27, the rotation direction of the large rubber wheel 9 and the small rubber wheel 21 is changed, so that the cable winding or unwinding function is realized. In the process of cable winding and unwinding, the cable 20 slides along the surface of the large rubber wheel 9, the threading pipe 13 protects and guides the cable 20, the multi-core slip ring 17 ensures the normal signal transmission and electrical connection of the cable during the winding and unwinding process, and the front cable isolation assembly 29 and the rear cable isolation assembly 30 isolate and arrange the front-end and rear-end cables 20 respectively, so as to prevent the cables 20 from being entangled or interfered with each other.

[0041] When the cable is wound and unwound alone, when the electromagnetic clutch is powered on, the electromagnetic clutch part 11 drives the large rubber wheel 9 to be attracted to the electromagnetic clutch main body 12, so that the large rubber wheel 9 is relatively fixedly connected with the hollow main shaft 1. Then, the driving motor 31 and the speed reducer motor 27 are powered on, the driving motor 31 drives the hollow main shaft 1 to rotate, and then drives the large rubber wheel 9 to rotate, and the speed reducer motor 27 drives the compression roller shaft 23 to rotate, so that the small rubber wheel 21 rotates. Since only the electromagnetic clutch is powered on, the electromagnetic clutches of the remaining large rubber wheels 9 are in a separated state, so the remaining large rubber wheels 9 will not rotate with the hollow main shaft 1. By controlling the forward rotation or reverse rotation of the driving motor 31 and the speed reducer motor 27, the cable winding or unwinding function can be realized. The working principles of the cable winding and unwinding alone at other positions are the same, which are realized by controlling the electromagnetic clutch, the driving motor 31 and the speed reducer motor 27 at the corresponding position.

[0042] Finally, it should be pointed out that the above description is only a preferred embodiment of the present application and is not used to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacements to some technical features, as long as they are within the spirit and principles of the present application.
