Description

Technical Field

[0001] This utility model belongs to the field of cable construction technology, specifically relating to an adjustable cable unwinding frame. Background Technology

[0002] A cable reel rack is a device used for cable reeling, unloading, and storage. In the laying and maintenance of power cables, cable reel racks are widely used to transport cables from the production site to the construction site and to achieve precise cable laying and reeling during the construction process.

[0003] Most existing cable unwinding frames are selected based on the diameter of the cable reel. Some are made by directly inserting a steel pipe into the cable reel and placing it on a support for support, in order to facilitate the unwinding and winding of the cable. However, none of the above methods are convenient for adjustment according to the diameter of the cable reel. Moreover, when unwinding and winding the cable, the friction between the cable reel and the support is large, and the force applied during unwinding and winding is large, which can cause problems such as difficulty in unwinding and winding.

[0004] Therefore, an adjustable cable unwinding rack was designed to overcome the aforementioned technical defects. Utility Model Content

[0027] This specific embodiment is an adjustable cable unwinding rack, the structural diagram of which is shown below. Figures 1-6 As shown, it includes two supports 1 and a support shaft 11 disposed between the two supports 1. The support 1 includes multiple crossbeams 2 and reinforcing beams 3. The reinforcing beams 3 are provided with through grooves 4, and reinforcing ribs 5 are fixedly connected to the corners of the reinforcing beams 3.

[0028] A fixed plate is fixedly connected to the inner side of the bracket 1 near the bottom surface. A telescopic rod 6 is fixedly connected to the top surface of the fixed plate. A support plate 7 is fixedly connected to the top surface of the telescopic rod 6. The support plate 7 is U-shaped and has a support assembly on its side wall. The telescopic rod 6 can be a hydraulic cylinder, an electric telescopic rod, or other lifting drive device.

[0029] A positioning plate 12 is sleeved on the side wall of the support shaft 11, and a positioning component is provided on the side wall of the positioning plate 12. An adjustment component is provided at the bottom corner of the bracket 1.

[0030] like Figure 2 and Figure 3 As shown, the support assembly includes two electric push rods 8 fixedly connected to the bottom surface of the support plate 7. Rectangular grooves 10 are respectively opened on the left and right side walls of the support plate 7. An extension plate 9 is provided in the rectangular groove 10. The output end of the electric push rod 8 is fixedly connected to the extension plate 9.

[0031] In order to further improve the stability of the cable reel, after the cable reel is lifted by the telescopic rod 6, to prevent the telescopic rod 6 from being subjected to excessive force, the extension plate 9 can be pushed out to both sides by the electric push rod 8. The extension plate 9 rests on the reinforcing beam 3 to support the cable reel and ensure safety during unwinding.

[0032] like Figure 4 As shown, the positioning assembly includes a bolt 13 threaded to the side wall of the positioning plate 12, and a plurality of screw holes 14 are provided on the side wall of the support shaft 11, with the bolt 13 threaded to the screw holes 14.

[0033] Specifically, both positioning plates 12 are detachably mounted on the support shaft 11. When installing the cable reel, only one positioning plate 12 needs to be removed. The cable reel can be limited on the support shaft 11 and located outside the bearing 15 by the positioning plates 12 on both sides.

[0034] like Figure 4 As shown, several bearings 15 are fitted on the side wall of the support shaft 11 between the two positioning plates 12. The bearings 15 can effectively reduce the friction between the cable reel and the support shaft 11.

[0035] like Figure 1 and Figure 5 As shown, the adjustment assembly includes a connecting plate 16 fixedly connected to the side wall of the bracket 1 near the bottom surface. A screw 17 is threadedly connected to the top surface of the connecting plate 16, and a pad 18 is rotatably connected to the bottom end of the screw 17.

[0036] Specifically, when the bracket 1 is placed on an uneven ground, the screw 17 can be turned with a wrench, and the screw 17 will drive the pad 18 to rise and fall, thereby controlling the tilt of each corner of the bracket 1 and keeping the bracket 1 in a stable state during use.

[0037] Several limiting plates 19 are fixedly connected to the side wall of the bracket 1, and the limiting plates 19 are located on both sides of the support plate 7. The limiting plates 19 can be used to position the extension plate 9 when it extends, and at the same time, they can prevent the support plate 7 from shaking during the unwinding process.

[0038] like Figure 2 As shown, the top surface of the support plate 7 has a placement groove 20, which is arc-shaped. This groove is used to store and limit the support shaft 11, further enhancing stability during winding and unwinding.

[0039] Working principle: First, the cable reel is hoisted and placed between two supports 1. Then, the support shaft 11 is inserted into the inside of the cable reel. Next, a positioning plate 12 is inserted into the support shaft 11 and attached to the side wall of the cable reel. The bolts 13 are tightened so that they are inserted into one of the screw holes 14, which is used to limit the cable reel on the bearing 15. Then, the position of the support shaft 11 is adjusted so that it is located in the placement groove 20 or above the support plate 7. Then, the telescopic rod 6 is activated according to the required unwinding height. The telescopic rod 6 drives the support plate 7 to move upward. The support plate 7 drives the cable reel to move upward through the support shaft 11. After the cable reel is raised to a suitable height, the electric push rod 8 is activated to drive the extension plate 9 to extend outward and place it on the reinforcing beam 3, which is used to provide auxiliary support for the support shaft 11. During the unwinding process, the bearing 15 can effectively reduce friction and achieve convenient unwinding.

[0040] All technical features in this embodiment can be freely combined according to actual needs.

[0041] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
