[0002] Copper conductors and cables are common and indispensable items in everyday life, primarily used for control installation, device connection, and power transmission. Copper conductors and finished cables are typically stored and transported on reels. During transportation, specialized lifting tools—cable reel lifting clamps—are required to efficiently and safely move the reels to their destination or load them onto trucks.

[0003] Traditional cable reels use two separate hook structures when they are installed. Positioning and fixing them are difficult, time-consuming, and pose a major safety hazard.

[0004] Cable drums are cylindrical in shape, and traditional fixing methods are prone to loosening or slipping, which can cause safety accidents. In addition, unstable fixings can cause the cable drum to tilt or fall during lifting, further increasing safety risks.

[0005] Prior art lacks dedicated equipment for hoisting reels, posing a serious safety hazard. Production workers typically use hooks formed by bending rebar to lift the reels. However, due to their simple structure and lack of a proper fixing mechanism, these hooks are prone to accidents such as the reels falling. Furthermore, due to the poorly designed hook structure, excessive compression between the hook and the reel can easily damage the reel, shortening its service life.

[0006] It can be seen from this that in the prior art, there is no professional lifting structure for the hoisting equipment of the reel, which makes it easy for the reel to be squeezed and damaged, and there is a defect of a major safety hazard. Utility Model Content

[0042] The disk lifting clamp of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments of the present invention.

[0043] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0044] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0045] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can, for example, be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0046] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0047] like Figures 1-8 As shown, the pan lifting clamp comprises a left clamp 1 and a right clamp 2, which primarily perform the clamping function; and a left chain 3 and a right chain 4, which connect to the lifting equipment (e.g., an overhead crane). The left and right clamps 1 and 2 are hinged at the middle, with the left and right chains 3 and 4 connected to their upper ends, respectively. Hooks 5 are integrally formed at the lower ends of the left and right clamps 1 and 2, respectively, with the hooks 5 facing each other.

[0048] By pulling up the left chain 3 and the right chain 4 at the upper ends of the left clamp 1 and the right clamp 2, the lower ends of the hinged left clamp 1 and the right clamp 2 are moved closer together, so that the hook 5 clamps and hooks the plate, thereby realizing the lifting operation of the plate 7.

[0049] To improve the load-bearing capacity of the hook 5 and ensure that the support area between the hook 5 and the reel 7 is increased during the lifting process, thereby preventing damage to the cables wrapped in the reel 7 due to squeezing and deformation of the end of the reel 7, the hook 5 includes: a back portion 51 that increases the strength of the hook 5's curved back, an inner cavity 52 that can extend into the edge of the reel, a rib portion 53 that strengthens the bottom of the hook 5, and a tip 54 that extends into the edge of the reel 7. The inner cavity 52 is formed on the opposite side of the two hooks 5, the back portion 51 is formed on the opposite side of the two hooks 5, the rib portion 53 is protruding from the bottom of the hook 5, and the tip 54 is formed on the outer side of the curved end of the hook 5.

[0050] The back 51 has a bulge that smoothly transitions to an outward arc, and the rib portion 53 has a bulge that smoothly transitions to a downward arc. The back 51 and the rib portion 53 have a smooth transition. The width of the lifting clamp does not change from the entire left clamp 1 or the right clamp 2 to the back 51 and the rib portion 53, thereby improving the load-bearing capacity of the entire lifting clamp.

[0051] To enhance the load-bearing capacity of tip 54, it is designed with a planar structure, creating a smooth transition between tip 54 and rib 53. The planar structure of tip 54 increases the support surface area for the hook 7, reducing the potential for damage to the hook 7. Furthermore, the planar structure of tip 54 fully transfers the load-bearing force to rib 53. Due to the larger size of rib 53, the overall strength of hook 5 is enhanced.

[0052] The upper end of the cross section of the inner cavity 52 of the hook 5 near the tip 54 is an arc. The upper side of the arc increases the support area of ​​the hook 5 and the plate 7, reduces the local force on the plate 7, and thus reduces the possibility of damage to the plate 7.

[0053] In order to facilitate the rotation of the left chain 3 and the right chain 4 during the lifting process, and to avoid the horizontal force of the left chain 3 and the right chain 4 on the left clamp 1 and the right clamp 2, thereby reducing the service life of the left clamp 1 and the right clamp 2, the lower ends of the left chain 3 and the right chain 4 are hinged to the upper ends of the left clamp 1 and the right clamp 2 respectively, and the upper ends of the left chain 4 and the right chain 5 are connected by a hanging ring. The left chain 3 and the right chain 4 are of the same length.

[0054] The larger hanging ring can be easily connected to the lifting equipment, and the same length of the left chain 3 and the right chain 4 can be ensured, and the same clamping force of the left clamp 1 and the right clamp 2 can be ensured, thereby achieving balanced lifting of the disk 7.

[0055] To accommodate the needs of reels 7 of varying sizes during the lifting process, the tip 54 provides planar support for the end of the reel 7, reducing the possibility of damage. The reel lifting clamp also includes an auxiliary sleeve 6 that assists the hook 5 in lifting the reel 7. The auxiliary sleeve 6 is mounted on the curved, extended end of the hook 5. The different sizes of the auxiliary sleeve 6 accommodate the needs of reels 7 of varying sizes. During the lifting operation, the auxiliary sleeve 6 provides a wider area of ​​support for the reel 7, reducing localized stress on the reel 7, thereby minimizing the possibility of damage to the reel 7 and, consequently, to the cable.

[0056] Since the auxiliary sleeve 6 has only two functional surfaces—one on the upper side providing lifting force to the plate 7 and the other on the lower side supporting the plate 7 to offset the clamping force—it is preferred that the auxiliary sleeve 6 be in the shape of a triangular prism. The two surfaces of the triangular prism satisfy the functional requirements, reducing the overall size of the auxiliary sleeve 6.

[0057] Specifically, the auxiliary sleeve 6 includes: an upper surface 61 for lifting the sling upward, a support surface 62 for supporting the end surface of the sling, and a lower bottom surface 63 for connecting. The upper surface 61 defines a hook cavity 64, the lower bottom surface 63 is below the hook cavity 64, and the side of the hook cavity 64 is the support surface 62.

[0058] The support surface 62 is a plane, which can support the end of the plate over a larger area. The upper end of the cross-section of the upper surface 61 close to the support surface 62 is an upwardly protruding arc, which supports the arc-shaped edge of the plate 7 during the process of lifting the plate 7.

[0059] To accommodate different lengths of reels, a lifting clamp can be used to lift them. Each hook 5 is equipped with multiple auxiliary sleeves 6, each with a sharp angle between the support surface and the upper surface. When in use, each auxiliary sleeve 6 can fit into the gap at the edge of the reel 7 to help lift the reel 7.

[0060] Since different lengths of reels 7 require different opening angles of the lifting clamps, the tilt angle of the support surface 62 changes. Therefore, the angles between the support surfaces 62 and the upper surface 61 of the multiple auxiliary sleeves 6 are different, so that different lengths of reels 7 use corresponding auxiliary sleeves 6, and the support surface 62 of the auxiliary sleeves 6 is parallel to the end surface of the reel 7.

[0061] Similarly, because the arc radius of different hoisting plates 7 varies, the corresponding auxiliary sleeves 6 have different diameters of support surfaces for the hoisting plates 7, thereby ensuring uniform surface support for all hoisting plates 7 and increasing support strength. Each hook 5 is equipped with multiple auxiliary sleeves 6, and the radius of the upwardly protruding arc surface of the upper surface 61 of each auxiliary sleeve 5 is the same as the arc radius of the corresponding hoisting plate 7.

[0062] That is to say, the tray 7 has fixed first, second, third, etc. lengths according to different models, and the corresponding auxiliary sleeve 6 is also provided with first, second, third fixed structures to meet the requirements of mutual cooperation.

[0063] In order to improve the buffering performance to a certain extent, reduce the wear on the disc, and increase the reusability life of the disc, the auxiliary sleeve 6 is made of hard plastic.

[0064] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
