Description

Technical Field

[0001] The utility model relates to the technical field of cables, and in particular to a large-scale reel-type cable unwinding and traction device. Background Art

[0002] Cables are widely used in various fields of the country's construction. Power transmission, communication transmission, control transmission, signal transmission, etc. are inseparable from cables. They play an important role from normal production operation to the development and construction of automation and intelligence. Nowadays, industrial and mining enterprises are in a period of rapid development. The use of cables is even more popular, and large cables are also being used more and more. Reel cables are made by winding the cable on a plate (wooden or steel). It can save storage space, protect the cable from bending, and facilitate large-scale storage and transportation. It is widely used in cables, optical cables, and wires.

[0003] The patent specification with the announcement number CN201307464Y discloses a cable pulling device, including a pulling head, a connecting rod and a pull ring connected in sequence, the pulling head has a cavity that can accommodate the end of the cable, one end of the connecting rod has a cavity that can accommodate the conductor in the center of the cable, and the connecting rod cavity is connected to the pulling head cavity. Due to the adoption of the above technical solution, the cable end is crimped by the cable pulling device and then the cable is pulled, the cable end is wrapped by the cable pulling device, and the push-pull force mainly acts on the cable end, which facilitates the pulling while avoiding damage to the cable outer sheath.

[0004] However, in the implementation of relevant technologies, it was found that the above technical solution has the following problems: when the reel cable arrives at the use site, because the cable is in a coiled form, it is necessary to arrange a special person to tear it apart before the next step of installation and use. A reel with a diameter of about 1 meter can be arranged for one worker to pull the cable, and the cable on the reel larger than 2 meters is very thick and heavy. At least 2 or 3 workers are required to be responsible for working together to unwind the cable to meet the progress requirements of the cable installation. The manual opening speed of the cable is slow, and the production progress is greatly restricted. There are often idle workers waiting for the workers to tear the wires apart before the installation can continue, which is time-consuming and labor-intensive, affecting the construction progress. Therefore, further improvement is needed. Utility Model Content

[0005] The utility model provides a large-scale reel-type cable pay-off and traction device, which solves the problem in the related technology that it is not conducive to improving the cable pay-off efficiency.

[0006] The technical solution of the utility model is as follows:

[0007] A large reel-type cable unwinding and traction device comprises a connecting roller, the outside of which is wound with a cable, a base is provided at the bottom of the connecting roller, a plurality of fixing plates are fixedly connected to the outside of the base, a connecting groove is provided inside the base, a sliding plate is provided inside the connecting groove, a threaded groove is provided inside the sliding plate, and a threaded rod is provided inside the threaded groove.

[0008] Preferably, the bottom of the connecting roller is connected to the top of the base via a bearing, and the plurality of fixing plates are distributed in a circular shape.

[0009] Preferably, the top of the fixed plate contacts the bottom of the connecting roller, and the outer surface of the sliding plate contacts the inside of the connecting groove.

[0010] Preferably, the threaded groove and the threaded rod are connected via threads, and two connecting strips are fixedly connected to both sides of the outside of the sliding plate.

DETAILED DESCRIPTION

[0027] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0028] like Figure 1 , Figure 3 and Figure 4As shown, this embodiment proposes a large-scale reel-type cable pay-off and traction device, including a connecting roller 1, a cable 2 is wound and connected to the outside of the connecting roller 1, a base 3 is provided at the bottom of the connecting roller 1, a plurality of fixed plates 4 are fixedly connected to the outside of the base 3, a connecting groove 5 is opened inside the base 3, a sliding plate 6 is provided inside the connecting groove 5, a threaded groove 7 is opened inside the sliding plate 6, and a threaded rod 8 is provided inside the threaded groove 7.

[0029] In this embodiment, the bottom of the connecting roller 1 is connected to the top of the base 3 via a bearing, and a plurality of fixing plates 4 are arranged in a circumferential distribution to facilitate the rotation of the connecting roller 1 .

[0030] In this embodiment, the top of the fixed plate 4 contacts the bottom of the connecting roller 1 , and the outer surface of the sliding plate 6 contacts the inside of the connecting groove 5 , which can facilitate the movement of the sliding plate 6 .

[0031] In this embodiment, the thread groove 7 and the threaded rod 8 are connected by threads, and two connecting strips 9 are fixedly connected to both sides of the outside of the sliding plate 6, which can facilitate the installation of the threaded rod 8.

[0032] In this embodiment, pulling grooves 10 are provided on both sides of the interior of the sliding plate 6 , and the two pulling grooves 10 are arranged in a circumferential distribution, which can facilitate the staff to pull the pulling grooves 10 .

[0033] When it is necessary to lay out and pull the cable 2, the staff first needs to move the sliding plate 6 inside the base 3, that is, the staff pulls the pulling groove 10 to make the sliding plate 6 located at the axial position of the connecting roller 1, and then places the entire device on the ground. During this process, since there is a certain friction between the sliding plate 6 and the base 3, the sliding plate 6 will not slide out of place. After that, the base 3 and the fixed plate 4 are used as the bottom. The sliding plate 6 will be gradually placed in the center position of the connecting roller 1 by the staff during the movement. Then the staff takes out the external threaded rod 8 and inserts it into the threaded groove 7 for rotation. During this process, the threaded rod 8 and the sliding plate 6 will be tightened and connected, so that the threaded rod 8 can be installed. Example

[0034] like Figure 1 , Figure 2 and Figure 5 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that a slot 11 is provided inside the threaded rod 8, and a rotating shaft 12 is provided inside the threaded rod 8.

[0035] In this embodiment, the rotating shaft 12 and the threaded rod 8 are movably connected via a damping bearing, and a rotating plate 13 is fixedly connected to the outside of the rotating shaft 12, so that the rotating shaft 12 can drive the rotating plate 13 to rotate.

[0036] In this embodiment, the rotating plate 13 extends to the outside of the slot 11 , and one end of the rotating plate 13 is fixedly connected to the rod body 14 , so that the rod body 14 can be easily rotated.

[0037] In this embodiment, the rod body 14 is zigzag in shape, and one end of the rod body 14 is fixedly connected to the traction shell 15 , which can facilitate the connection and support of the traction shell 15 .

[0038] In this embodiment, the traction shell 15 is shaped as an inverted bucket, and a gauze protective layer is provided at the inner end of the traction shell 15 to facilitate protection of the cable.

[0039] When it is necessary to pull the cable 2 through the traction shell 15, the staff needs to pass the cable 2 through the inside of the traction shell 15. When the cable 2 passes through the inside of the traction shell 15, the staff needs to hold the cable head at the top of the cable 2, and then climb to a high altitude through the climbing equipment. During the climbing process, the traction shell 15 will limit the cable 2. Since the cable 2 will synchronously drive the connecting roller 1 to rotate during the continuous line release, the connecting roller 1 will rotate synchronously, and the base 3 at the bottom of the connecting roller 1 will not rotate because it is connected to the connecting roller 1 by a bearing. At the same time, the rotating shaft 12 and the threaded rod 8 are movably connected by a damping bearing, so it has a certain support, so that the cable 2 can be more conveniently laid out, and multiple staff members do not need to separate the cable 2, thereby ensuring work efficiency;

[0040] When the threaded rod 8 needs to be disassembled, the staff can rotate the threaded rod 8 in the opposite direction. During the rotation, the threaded rod 8 will synchronously drive the rotating shaft 12 and the rotating plate 13 to rotate. During the rotation, the rotating plate 13 will synchronously drive the rod body 14 and the traction shell 15 to rotate. When the threaded rod 8 is separated from the threaded groove 7, the staff can press the rotating plate 13 in the direction of the slot 11. During the rotation, the rotating plate 13 will synchronously drive the rod body 14 and the traction shell 15 to rotate, so that the threaded rod 8 and the rotating plate 13 can be in an acute angle as a whole, ensuring portability.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
