Cable Winding Device

This application claims the benefit of Chinese Patent Application No. CN202421120431.7 filed on May 21, 2024, in the State Intellectual Property Office of China, the whole disclosure of which is incorporated herein by reference.

The present disclosure relates to a cable winding device and a method for winding a cable using the cable winding device.

In the prior art, in order to facilitate transportation and storage, cables are typically coiled into cable rolls through cable winding devices. In the prior art, cable winding devices traditionally include a drum, and a driving device that drives the drum to rotate. When the drum rotates, the cable is wound on the drum. In this way, the cable can be coiled into a cable roll. However, in the prior art, when the drum is placed vertically, the cable roll wound on the drum is prone to slide off the drum under its own weight, which reduces the efficiency of cable winding.

According to an embodiment of the present disclosure, a cable winding device includes a mounting plate, first and second driving mechanisms, a rotating plate, a drum, and multiple pallets. The rotation shaft is rotatably mounted on the mounting plate. The first driving mechanism is installed on the mounting plate and drives the rotation shaft to rotate. The rotating plate is arranged below the mounting plate, and connected to, and rotatable together with, the rotation shaft. The multiple pallets are installed on the rotating plate in a movable manner and distributed at intervals in the circumferential direction, and movable synchronously between an extended position and a retracted position along a radial direction of the rotation shaft. The second driving mechanism is installed on the mounting plate and connected to the multiple pallets, and drives the multiple pallets to move synchronously between the extended position and the retracted position. When the supports are in the extended position, a cable roll wound on the drum is retained on the drum by the supports. When the pallet is in the retracted position, the pallet does not interfere with the cable roll on the drum, allowing the cable roll to be unloaded from the drum.

The features disclosed in this disclosure will become more apparent in the following detailed description in conjunction with the accompanying drawings, where similar reference numerals always identify the corresponding components. In the accompanying drawings, similar reference numerals typically represent identical, functionally similar, and/or structurally similar components. Unless otherwise stated, the drawings provided throughout the entire disclosure should not be construed as drawings drawn to scale.

Exemplary embodiments of the present disclosure will be described hereinafter in detail with reference to the attached drawings, wherein the like reference numerals refer to the like elements. The present disclosure may, however, be embodied in many different forms and should not be construed as being limited to the embodiment set forth herein; rather, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the concept of the disclosure to those skilled in the art.

In the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the disclosed embodiments. It will be apparent, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are schematically shown in order to simplify the drawing.

According to an embodiment of the present disclosure, a cable winding device comprises: a mounting plate; a rotation shaft rotatably mounted on the mounting plate; a first driving mechanism installed on the mounting plate to drive the rotation shaft to rotate; a rotating plate located below the mounting plate and connected to the rotation shaft, and capable of being rotated together with the rotation shaft; multiple arc-shaped plates which are fixed to the bottom surface of the rotating plate and distributed at intervals in the circumferential direction around the axis of the rotation shaft to form a drum for winding a cable; multiple pallets which are installed on the rotating plate in a movable manner and distributed at intervals in the circumferential direction, and can be moved synchronously between an extended position and a retracted position along the radial direction of the rotation shaft; and a second driving mechanism which is installed on the mounting plate and connected to the multiple pallets, used to drive the multiple pallets to move synchronously between the extended position and the retracted position. When the pallet is in the extended position, a cable roll wound on the drum is suitable for being supported on the pallet to prevent the cable roll from slipping off the drum; when the pallet is in the retracted position, the pallet does not interfere with the cable roll on the drum, allowing the cable roll to be unloaded from the drum.
