Description

Technical Field

[0001] This utility model relates to the field of stranded wire reel technology, specifically a stranded wire reel for transporting power cables. Background Technology

[0002] Cable reels are a type of reel specifically designed for wires and cables. They are often made of steel or steel-wood structures. Steel structures are sturdy, not easily damaged, provide good protection for cables, and can be reused.

[0003] Traditional cable reels require fixing one end of the cable to the winding post before winding. The winding post is typically cylindrical, so tape is often used to attach one end of the cable to the post before winding. This process is cumbersome and affects the smoothness of the cable winding. Furthermore, due to their circular shape and weight, laying the reel flat during transport can cause the cables to deform from mutual compression, hindering subsequent cable laying and hoisting. Therefore, they are typically transported with both ends of the reel on the ground. However, this method is difficult to secure, and insecure securing can easily lead to transportation accidents. To address these issues, we propose a new type of cable reel for power cable transportation. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a stranded reel for transporting power cables, which has the advantages of facilitating the fixing of cable ends during cable winding and the securing of the entire stranded reel during transportation, thereby reducing transportation accidents and solving the aforementioned technical problems.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a stranded reel for transporting power cables, comprising a winding post, with limiting discs fixedly connected to both ends of the winding post, a straight groove penetrating through the outer surface of the winding post, and a circular plate fixedly connected inside the winding post, a straight rod inserted into the circular plate, a spring sleeved on the outer surface of the straight rod, a clamping head fixedly connected to one end of the straight rod, and a lever fixedly connected to the other end of the straight rod, a support plate rotatably connected to the end face of the limiting disc, a receiving cavity formed inside the support plate, a fixed plate rotatably connected inside the receiving cavity, a locking bolt threaded to one end of the fixed plate, a locking bolt threaded to one end of the support plate, and a U-shaped groove formed on the front side of the support plate.

[0008] Preferably, the two sides of the clamping head are in sliding contact with the straight groove, and the two sides of the lever are also in sliding contact with the straight groove.

[0009] With the above technical solution, by moving the lever, the straight rod is driven, which in turn drives the clamping head to compress the spring and retract. This creates a certain gap between the end face of the clamping head and one of the limiting discs, allowing the cable end to be inserted into the straight groove. The cable end is positioned between the clamping head and one of the limiting discs. When the lever is released, the spring drives the clamping head to abut against the outer surface of the cable to fix it in place.

[0010] Preferably, the clamping head has an arc-shaped groove on the side away from the straight rod, and multiple arc-shaped clips are fixedly connected in the arc-shaped groove.

[0011] By using the above technical solution, by opening an arc-shaped groove on one side of the clamping head to match the shape of the cable, and by setting multiple arc-shaped clips in the arc-shaped groove to increase roughness, the friction between the clamping head and the cable can be increased, so that the cable is not easy to detach from the clamping head during the initial winding.

[0012] Preferably, the support plate and the fixed plate are rotatably connected by a pin, the pin is internally threaded with a second locking bolt, and a first screw hole is formed on the end face of the limiting plate.

[0013] With the above technical solution, when transporting the strand reel, the support plate can be unfolded so that one end contacts the bottom of the inside of the transport vehicle. Two support plates are rotatably connected to the limiting plate. After both support plates are unfolded, they can provide a certain support for the limiting plate.

[0014] Preferably, a second screw hole is provided on the end face of the limiting plate, and the second screw hole is threadedly engaged with the first locking bolt.

[0015] With the above technical solution, after the support plate is unfolded, the fixing plate is unscrewed from the receiving cavity, and then the No. 1 locking bolt is threaded into the No. 2 screw hole. In this way, a triangular area is formed between the limiting plate, the support plate and the fixing plate, which makes the limiting plate well stabilized, enhances the stability of the entire stranded coil during transportation and reduces the accident rate during transportation.

[0016] Preferably, the width of the U-shaped groove is adapted to the outer diameter of the screw of the No. 1 locking bolt.

[0017] The above technical solution involves unscrewing the No. 1 locking bolt out of the No. 2 screw hole, then screwing the fixing plate into the receiving cavity for storage, and finally rotating the support plate to align the No. 2 locking bolt with the No. 1 screw hole. Then, the No. 2 locking bolt is screwed into the No. 1 screw hole. This allows the support plate and fixing plate to be folded and stored without affecting the cable winding of the stranded reel.

[0018] Compared with the prior art, this utility model provides a stranded reel for transporting power cables, which has the following advantages:

[0019] 1. This utility model uses a lever to drive a straight rod, which in turn drives the clamping head to compress the spring and retract. This creates a gap between the end face of the clamping head and one of the limiting discs, allowing the cable end to be inserted into the straight groove. The cable end is positioned between the clamping head and one of the limiting discs. When the lever is released, the spring causes the clamping head to press against the outer surface of the cable, thus fixing it in place. This allows for quick and easy securing of the cable end before winding it up.

[0020] 2. When transporting the stranding reel, this utility model allows the support plate to be unfolded so that one end contacts the bottom of the transport vehicle's interior. Then, the fixing plate is unscrewed from the receiving cavity, and the first locking bolt is threaded into the second screw hole. This forms a triangular area between the limiting plate, the support plate, and the fixing plate, which effectively stabilizes the limiting plate, enhances the stability of the entire stranding reel during transport, and reduces the accident rate during transport.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-4A stranded reel for transporting power cables includes a winding post 1, with limiting plates 2 fixedly connected to both ends of the winding post 1. A straight groove 3 is formed through the outer surface of the winding post 1, and a circular plate 4 is fixedly connected inside the winding post 1. A straight rod 5 is inserted into the circular plate 4, and a spring 6 is sleeved on the outer surface of the straight rod 5. A clamping head 7 is fixedly connected to one end of the straight rod 5, and a lever 8 is fixedly connected to the other end of the straight rod 5. A support plate 9 is rotatably connected to the end face of the limiting plate 2. A receiving cavity 10 is formed inside the support plate 9, and a fixing plate 11 is rotatably connected inside the receiving cavity 10. A locking bolt 12 is threaded to one end of the fixing plate 11, and a locking bolt 13 is threaded to one end of the support plate 9. A U-shaped groove 14 is formed on the front side of the support plate 9.

[0028] Specifically, the two sides of the clamping head 7 slide in contact with the straight groove 3, and the two sides of the lever 8 also slide in contact with the straight groove 3. The advantage is that by moving the lever 8, the straight rod 5 is driven, which in turn drives the clamping head 7 to compress the spring 6 and retract. This creates a certain gap between the clamping head 7 and the end face of one of the limiting discs 2, allowing the cable end to be inserted into the straight groove 3, and ensuring that the cable end is between the clamping head 7 and one of the limiting discs 2. When the lever 8 is released, the spring 6 drives the clamping head 7 to abut against the outer surface of the cable to form a fixed connection.

[0029] Specifically, an arc-shaped groove is provided on the side of the clamping head 7 away from the straight rod 5, and multiple arc-shaped retaining strips are fixedly connected in the arc-shaped groove. The advantage is that by matching the shape of the cable with the arc-shaped groove on one side of the clamping head 7, and by setting multiple arc-shaped retaining strips in the arc-shaped groove to increase the roughness, the friction with the cable can be increased, so that the cable is not easy to detach from the clamping head 7 during the initial winding.

[0030] Specifically, the support plate 9 and the fixed plate 11 are rotatably connected by a pin, and the pin is internally threaded with a second locking bolt 13. A first screw hole 15 is provided on the end face of the limiting plate 2. The advantage is that when transporting the strand, the support plate 9 can be unfolded so that one end contacts the bottom of the transport vehicle's interior. Two support plates 9 are rotatably connected to the limiting plate 2, and when both support plates 9 are unfolded, they can provide a certain degree of support for the limiting plate 2.

[0031] Specifically, a second screw hole 16 is provided on the end face of the limiting plate 2, and the second screw hole 16 is threadedly engaged with the first locking bolt 12. The advantage is that when the support plate 9 is unfolded, the fixing plate 11 is unscrewed from the receiving cavity 10, and then the first locking bolt 12 is threadedly connected to the second screw hole 16. In this way, a triangular area is formed between the limiting plate 2, the support plate 9, and the fixing plate 11, which allows the limiting plate 2 to be well stabilized, enhances the stability of the entire stranded coil during transportation, and reduces the accident rate during transportation.

[0032] Specifically, the width of the U-shaped groove 14 is adapted to the outer diameter of the screw of the first locking bolt 12. The advantage is that by unscrewing the first locking bolt 12 out of the second screw hole 16, then screwing the fixing plate 11 into the receiving cavity 10 for storage, and finally rotating the support plate 9 so that the second locking bolt 13 can be aligned with the first screw hole 15, and then screwing the second locking bolt 13 into the first screw hole 15, the support plate 9 and the fixing plate 11 can be folded and stored without affecting the cable winding of the stranded reel.

[0033] In use, the stranded reel is placed on a cable winding device. By moving the lever 8, the straight rod 5 is driven, which in turn drives the clamping head 7 to compress the spring 6 and retract. This creates a gap between the clamping head 7 and the end face of one of the limiting discs 2. The cable end is then inserted into the straight groove 3, with the cable end positioned between the clamping head 7 and one of the limiting discs 2. When the lever 8 is released, the spring 6 drives the clamping head 7 to abut against the outer surface of the cable, thus fixing it in place. The cable winding device is then used to begin winding the cable, so that the cable is wound around the winding post 1. When transporting the stranded reel, the support plate 9 can be unfolded by loosening the second locking bolt 13, so that one end contacts the bottom of the transport vehicle's interior. The fixing plate 11 is then unscrewed from the receiving cavity 10, and the first locking bolt 12 is threaded into the second screw hole 16. This creates a triangular area between the limiting disc 2, the support plate 9, and the fixing plate 11, which effectively stabilizes the limiting disc 2 and enhances the stability of the entire stranded reel during transport.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
