[0030] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0031] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

The rewinding assembly 140 is spaced apart from the cable reel 110, used to be installed on the body 200, and used to rewind and unwind the cable.

[0035] It should be understood that in the embodiment of the present invention, the cable reel 110 is used to store cables, and the cables can be stored on the cable reel 110 by winding. The support assembly 120 is used to support the cable reel 110, wherein the support cylinder 121 supports the cable reel 110 on the one hand and can adjust the cable reel 110 on the other hand; the support member 122 can support the cable reel 110, and the support member 122 is rotatably connected to the vehicle body 200. Under the action of the support cylinder 121, the cable reel 110 and the support member 122 can rotate relative to the vehicle body 200, thereby realizing the position adjustment of the cable reel 110. The rotation drive assembly 130 is used to drive the cable reel 110 to rotate. When the cable reel 110 rotates, the cable can be wound on the reel or detached from the reel. The retractable assembly 140 is used for retracting and releasing cables.

[0036] At the same time, it should be noted that when the automatic cable winding and unwinding device 100 described in the embodiment of the present invention is in use, the supporting oil cylinder 121 is controlled to adjust the position of the cable reel 110. After the position is adjusted, the rotation drive component 130 and the retracting component 140 are started to automatically wind and unwind the cable. This step can be fully automated, thereby saving labor costs. When the automatic cable winding and unwinding device 100 is applied to a cable transfer vehicle, the operator can manually control the above steps through the operating equipment in the cab 300, and of course, the above steps can also be automatically implemented.

The rotating driving member 131 is installed on the support member 122, and then the cable reel 110 is driven to rotate by the first transmission member 132 and the second transmission member 133, which is beneficial to the structural design and improves the reliability of the transmission.

[0039] Furthermore, the rotation drive assembly 130 may also include a synchronous belt 134, and the first transmission member 132 is connected to the second transmission member 133 through the synchronous belt 134. In other words, the first transmission member 132 and the second transmission member 133 are driven by a belt; in this case, the first transmission member 132 and the second transmission member 133 may be pulleys. Belt drive has a good transmission effect, and has a simple structure and is easy to assemble.
