Description

Technical Field

[0001] This utility model relates to the field of communication technology, and in particular to a cable winding and unwinding device. Background Technology

[0002] Communication cables are an indispensable basic component of modern communication systems and are widely used in various communication networks, including many important industries such as power, communication, and transportation. The cables are wound around the outside of the roller and are usually assisted by cable winding devices.

[0003] However, when dealing with cables of different diameters and hardness, traditional cable winding devices are prone to problems such as excessive squeezing, stretching or friction during winding due to unbalanced tension control, which can lead to damage to the cable sheath and breakage of the internal core.

[0004] In view of this, we have studied and improved the existing problems to provide a cable winding and unwinding device, aiming to solve the problems and improve its practical value through this technology. Summary of the Invention

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a cable winding and unwinding device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a cable winding and unwinding device, including a load-bearing plate, two supports fixedly installed on the top of the load-bearing plate, a reciprocating screw and a rotating shaft rotatably installed between the two supports, a limit rod fixedly installed above the reciprocating screw, a moving block slidably provided on one side of the support, a piston rod A slidably installed inside the moving block, a spring A fixedly connected to the bottom end of the moving block, a ring fixedly installed below the piston rod A, and an air pipe connected to one side of the moving block;

[0007] A fixed ring is fixedly installed on the outer wall of the rotating shaft, and a sliding ring is slidably installed on the outer wall of the rotating shaft. A hydraulic rod is fixedly provided between the fixed ring and the sliding ring. Six fixed blocks are fixedly installed on one side of the sliding ring. Six fixed blocks are fixedly installed on one side of the fixed ring. Rotating rod A and rotating rod B are hinged between the two fixed blocks. A support block is fixedly installed above the rotating rod A. An arc plate is fixedly installed above the support block. A piston rod B is fixedly installed on one side of the sliding ring.

[0008] Preferably, a hinge is rotatably mounted at one end of the trachea, and a torsion spring is provided inside the hinge.

[0009] Preferably, an interface is fixedly installed on one side of the sliding ring.

[0010] Preferably, one of the brackets has a cavity inside.

[0011] Preferably, a spring A is fixedly installed below the piston rod A, and one end of the spring A is fixedly installed at the bottom end of the moving block.

[0012] Preferably, a guide rod is fixedly installed inside the cavity.

[0013] Preferably, the reciprocating lead screw and the moving block are connected by a ball nut pair.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. When collecting cables, first insert the cable through the ring into the interface. Then, control the hinge height between rotating rod A and rotating rod B by adjusting the extension and retraction of the hydraulic rod. The change in hinge height will drive the support block to move, and then the support block will drive the arc plate to move synchronously. At the same time, the extension and retraction of the hydraulic rod will cause the piston rod B to pump air, which will draw out the air in the air chamber above the piston rod A to create a negative pressure environment. The negative pressure environment will generate a pressure difference on both sides of the piston rod A. The pressure difference on both sides will provide support force for the auxiliary spring A, thereby adapting to cables of different weights and realizing adaptive adjustment of the winding coil size according to the cable size. At the same time, the negative pressure can also further enhance the shock absorption effect and the friction and torsional resistance during the guidance process.

[0016] 2. When it is necessary to collect messy cables, first start the drive motor and the forward and reverse motors. The drive motor drives the reciprocating screw to rotate and the rotating shaft to rotate. The rotation of the reciprocating screw drives the moving block to move, and the rotation of the rotating shaft can realize the winding and collection of cables. When the cable passes through the ring, the tangential force of the cable will cause the ring to be pressed down, which in turn drives the piston rod A to press down. At the same time, the spring A will drive the piston rod A to return to its original position. As the cable moves with the moving block, the angle at which the cable enters the ring is different, and the downward pressure generated is different. The piston rod A will continue to perform piston movement. The shock absorption component realizes the shock absorption effect of the cable and can also enhance the friction and torsional performance of the cable when passing through the ring.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Therefore, the following detailed description of the embodiments of this utility model provided in the drawings is not intended to limit the scope of the claimed utility model, but merely to illustrate selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0028] See Figures 1 to 8 As shown, this utility model provides a cable winding and unwinding device, including a load-bearing plate 1, two brackets 20 are fixedly installed on the top of the load-bearing plate 1, a reciprocating screw 2 and a rotating shaft 10 are rotatably installed between the two brackets 20, a limit rod 3 is fixedly installed on the top of the reciprocating screw 2, a moving block 4 is slidably provided on one side of the bracket 20, a piston rod A5 is slidably installed inside the moving block 4, a spring A6 is fixedly connected to the bottom end of the moving block 4, a ring 7 is fixedly installed below the piston rod A5, and an air pipe 22 is connected to one side of the moving block 4.

[0029] It should be noted that during cable collection, the cable is first inserted through the ring 7 into the interface 21. Then, the hinge height between the rotating rod A14 and the rotating rod B15 is controlled by adjusting the extension and retraction of the hydraulic rod 13. The change in the hinge height causes the support block 16 to move, which in turn causes the arc plate 17 to move synchronously. At the same time, the extension and retraction of the hydraulic rod 13 causes the piston rod B19 to draw air out, creating a negative pressure environment. The negative pressure environment generates a pressure difference on both sides of the piston rod A5, which provides support force for the auxiliary spring A6. This allows for the adaptation of cables of different weights, achieving adaptive adjustment of the winding coil size according to the cable size. At the same time, the negative pressure further enhances the shock absorption effect and the friction and torsional resistance during the guiding process.

[0030] A fixed ring 11 is fixedly installed on the outer wall of the rotating shaft 10, and a sliding ring 12 is slidably installed on the outer wall of the rotating shaft 10. A hydraulic rod 13 is fixedly provided between the fixed ring 11 and the sliding ring 12. Six fixed blocks 18 are fixedly installed on one side of the sliding ring 12. Six fixed blocks 18 are fixedly installed on one side of one of the fixed rings 11. A rotating rod A14 and a rotating rod B15 are hinged between the two fixed blocks 18. A support block 16 is fixedly installed above the rotating rod A14. An arc plate 17 is fixedly installed above the support block 16. A piston rod B19 is fixedly installed on one side of the sliding ring 12.

[0031] It should be noted that when collecting messy cables, the drive motor and the forward and reverse motors are started first. The drive motor drives the reciprocating screw 2 to rotate and the rotating shaft 10 to rotate. The rotation of the reciprocating screw 2 drives the moving block 4 to move, and the rotation of the rotating shaft 10 realizes the winding and collection of the cables. When the cable passes through the ring 7, the tangential force of the cable will cause the ring 7 to be pressed down, which in turn drives the piston rod A5 to press down. At the same time, the spring A6 will drive the piston rod A5 to return to its original position. During the process of the cable moving with the moving block 4, the angle at which the cable enters the ring 7 is different, and the downward pressure generated is different. The piston rod A5 will continue to perform piston movement. The shock absorption component realizes the shock absorption effect of the cable and can also enhance the friction and anti-torsion performance of the cable when passing through the ring 7.

[0032] In an optional embodiment, a hinge 8 is rotatably mounted at one end of the air tube 22, and a torsion spring is provided inside the hinge 8.

[0033] It should be noted that hinge 8 can enhance the sealing of enclosed spaces, and the torsion spring can automatically reset after hinge 8 has completed its flip.

[0034] In an optional embodiment, an interface 21 is fixedly mounted on one side of the sliding ring 12.

[0035] It should be noted that the design of interface 21 can provide stable constraints for the cable during the initial winding stage, effectively preventing the problem of loosening of the winding.

[0036] In an alternative embodiment, one of the supports 20 has a cavity 23 inside.

[0037] It should be noted that the cavity 23 is designed to provide a gas flow path during the evacuation process of the piston rod B19.

[0038] In an optional embodiment, a spring A6 is fixedly mounted below the piston rod A5, with one end of the spring A6 fixedly mounted at the bottom end of the movable block 4.

[0039] It should be noted that when subjected to gravity, spring A6 will compress downwards; when gravity decreases, spring A6 releases its stored elastic potential energy, thereby causing piston rod A5 to return to its original position.

[0040] In an optional embodiment, a guide rod 9 is fixedly installed inside the cavity 23.

[0041] It should be noted that the guide rod 9 can squeeze the hinge 8, thereby causing the hinge 8 to flip over, and after flipping over, air can be extracted.

[0042] In an optional embodiment, the reciprocating screw 2 and the moving block 4 are connected by a ball nut pair.

[0043] It should be noted that the reciprocating screw 2 and the moving block 4 are connected by a ball nut pair, which can realize that the reciprocating screw 2 and the moving block 4 move in opposite directions under the same rotation operation.

[0044] Working principle: When collecting cables, the cables are first inserted into the interface 21 through the ring 7. Then, the hinge height between the rotating rod A14 and the rotating rod B15 is controlled by adjusting the extension and retraction of the hydraulic rod 13. The change in the hinge height causes the support block 16 to move, and the support block 16 causes the arc plate 17 to move synchronously. At the same time, the extension and retraction of the hydraulic rod 13 causes the piston rod B19 to draw air out, creating a negative pressure environment. The negative pressure environment generates a pressure difference on both sides of the piston rod A5, and the pressure difference on both sides provides support force for the auxiliary spring A6.

[0045] When it is necessary to collect messy cables, the drive motor and the forward and reverse motors are started first. The drive motor drives the reciprocating screw 2 to rotate and the rotating shaft 10 to rotate. The rotation of the reciprocating screw 2 drives the moving block 4 to move. The rotation of the rotating shaft 10 realizes the winding and collection of cables. When the cable passes through the ring 7, the tangential force of the cable will cause the ring 7 to be pressed down, which in turn drives the piston rod A5 to press down. At the same time, the spring A6 will drive the piston rod A5 to return to its original position. As the cable moves with the moving block 4, the angle at which the cable enters the ring 7 is different, and the downward pressure generated is different. The piston rod A5 will continue to perform piston movement.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
