Description

Technical Field

[0001] This utility model relates to the field of cable reels, and in particular to a cable reel lifting device. Background Technology

[0002] Cable reels, as important carriers for cable transportation and storage, typically consist of a central shaft and side reels. During construction and warehousing, cable reels require frequent handling and hoisting. Especially for vertically placed cable reels, their significant weight and unique shape make safe and reliable lifting a persistent technical challenge in the industry.

[0003] Most existing cable reel lifting devices use wire rope binding or simple hook attachment for lifting. Although this method is simple in structure, it has the following shortcomings: First, it is difficult to fix the lifting point position, which makes the cable reel easy to shake and shift during the lifting process, posing a safety hazard and easily damaging the cable reel. Second, for vertically placed cable reels, it is difficult to set the binding point outside the central axis, resulting in insufficient lifting stability and easy slippage.

[0004] Therefore, there is an urgent need for a cable reel lifting device with a reasonable structure, reliable force bearing and strong stability to solve the problems of slippage, uneven force bearing and poor stability in the process of vertical cable reel lifting in the existing technology. Utility Model Content

[0005] This utility model provides a cable reel lifting device to solve related technical problems in the background art.

[0006] The technical solution provided by this utility model is as follows: a cable reel lifting device, comprising: a lifting beam, the lower end of which is connected to a fork structure via an L-shaped connector; The fork-holding structure consists of two extended fork-holding arms, which are arranged opposite each other, and their openings are used to fit around the outside of the cable reel's central shaft. The connector works with the lifting beam to form a clamp at the edge of the cable reel.

[0007] In one embodiment, the two fork arms are U-shaped.

[0008] In one embodiment, the spacing between the forks within the fork arm is relative to the radius of the cable reel's central axis.

[0009] In one embodiment, the spacing between the connector and the lifting beam matches the thickness of the cable reel side plate.

[0010] In one embodiment, reinforcing ribs are connected between the connector and the lifting beam.

[0011] In one embodiment, a lifting ring is provided at the upper end of the lifting beam near the fork structure.

[0012] In one embodiment, the inner surfaces of the fork arm and the connector are provided with a rubber layer.

[0013] Compared with the prior art, the beneficial effects of this utility model are: (1) The cable reel lifting device of this utility model adopts a lifting beam and an L-shaped connector to connect the fork structure. The fork arm hugs the central axis of the cable reel, and the connector and the lifting beam form a clamp at the edge of the cable reel, which achieves the purpose of stably clamping the cable reel in a vertical position. This realizes the reliable lifting and transportation of the cable reel, and solves the problem that existing lifting devices are not easy to lift when transporting vertical cable reels.

[0016] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0017] like Figure 1-2 As shown, this utility model is a cable reel lifting device, including a lifting beam 1. The lower end of the lifting beam 1 is connected to a clamping fork structure 3 via an L-shaped connector 2. The clamping fork structure 3 consists of two extending clamping fork arms 31, which are arranged opposite to each other. Their openings are used to clamp around the outside of the central shaft 4 of the cable reel during lifting. The connector 2 cooperates with the lifting beam 1 to form a clamp at the side plate 5 of the cable reel, ensuring stability during lifting.

[0018] Specifically, the two fork arms 31 have a U-shaped structure, which matches the external dimensions of the central axis 4 of the cable reel. During lifting, they can be more stably clamped on the outside, improving the stability during the lifting process.

[0019] The fork spacing between the fork arms 31, i.e. the forward depth, is larger than the radius of the cable reel's central axis 4. This allows the fork arms 31 to provide a longer support surface for the cable reel's side plate 5 when they are close to the outer wall of the central axis 4, thereby improving the reliability and stability of the load during hoisting.

[0020] The spacing between the connector 2 and the lifting beam 1 matches the thickness of the cable reel side plate 5, thereby forming a clamp at the side plate of the cable reel to ensure stability during the lifting process.

[0021] In this embodiment, in order to improve the overall strength, a reinforcing rib 6 is provided between the connector 2 and the lifting beam 1 to prevent deformation when subjected to force.

[0022] In this embodiment, a lifting ring 7 is provided at the upper end of the lifting beam 1 near the fork structure 3 for connecting to the lifting equipment. In specific implementation, the crane hook can be engaged with the lifting ring 7 to ensure force balance during lifting.

[0023] To further enhance the friction between the cable reel's central shaft 4 and its side discs 5, and to prevent slippage during hoisting, the inner surfaces of the fork arm 31 and the connector 2 are provided with a rubber layer. This rubber layer increases the coefficient of friction and prevents direct metal-to-cable reel contact, thus avoiding wear.

[0024] The working principle of this embodiment is as follows: The lifting device is moved to the position of the vertically placed cable reel, so that the two clamping arms 31 are respectively wrapped around the outside of the cable reel's central shaft 4; the L-shaped connector 2 is below and to the side of the cable reel's side plate 5, and the lifting beam 1 is above the cable reel's side plate 5. The L-shaped connector 2 and the lifting beam 1 form a clamp on the outside of the cable reel's side plate 5; the clamping arms 31 limit the movement of the cable reel's central shaft 4, and the L-shaped connector 2 and the lifting beam 1 cooperate to limit the movement of the side plate 5; in the vertical direction, the load is transferred by the lifting ring 7 and the lifting equipment, thereby achieving reliable lifting of the cable reel.

[0025] The cable reel lifting device of this utility model adopts a method of connecting the lifting beam 1 and the L-shaped connector 2 to the clamping fork structure 3. The clamping fork arm 31 clamps the central shaft 4 of the cable reel, and the connector 2 and the lifting beam 1 form a clamp at the side plate 5 of the cable reel. This achieves the purpose of stably clamping the cable reel in a vertically placed state, thereby realizing the reliable lifting and transportation of the cable reel, and solving the problem that existing lifting devices are not easy to lift when transporting vertical cable reels.
