The utility model includes a base plate, on which a tensioning mechanism and a configuration mechanism are provided. The tensioning mechanism includes a U-shaped rod module fixedly connected to the top of the base plate, and a motor fixedly connected to the right side of the U-shaped rod module. By setting up the tensioning mechanism, in use, one end of the cable can be passed through a sliding frame and wound around multiple tensioning rings.

Description

Technical Field

[0001] This utility model belongs to the field of marine technology, and in particular relates to an automatic tensioning and retraction frame for preventing ship cables from tangling. Background Technology

[0002] In the prior art, a search revealed a Chinese patent entitled "An Automatic Tensioning and Retracting Frame for Anti-Tangle of Ship Cables," with publication number "CN216851229U." This patent mainly includes a support base, a mounting frame, and a wheel frame. Guide rings are installed at both ends of the upper surface of the support base, and a tensioning wheel is installed on the top of the wheel frame. The mounting frame is fixedly connected to both ends of the support base, and the mounting frame has evenly distributed mounting holes inside. The wheel frame is installed in the middle of the upper surface of the support base, and the wheel frame is movably connected to the support base by sliding. A detachable limiting structure is provided between the two. Through the guide rings and adjustment mechanism, the utility model allows the retracting frame to be arbitrarily adjusted according to cables of different thicknesses, providing a dual limitation function for the position of the cable. This makes it more widely applicable, more flexible, and more practical. The buffer structure provides the wheel axle with a certain elastic space for self-adaptive adjustment, reducing the risk of cable breakage under stress and thus extending the service life of the cable.

[0003] Existing tension retraction frames are ill-suited to adapting well to the tension forces during cable winding. When cable tension increases, the frame fails to effectively buffer or balance the force, potentially causing excessive slack in localized areas. Conversely, when tension decreases, it cannot provide sufficient additional tension to maintain the desired tightness. This poor fit between the tension frame and the cable tension results in the wound cable not being tightly packed on the reel, but rather remaining loose. Loose cables not only occupy more storage space but may also lead to tangling and knotting during subsequent handling and use, severely impacting cable quality and performance. Utility Model Content

[0004] The purpose of this invention is to provide an automatic tensioning and retracting frame for preventing tangling of marine cables. By incorporating a tensioning mechanism, it solves the problem that when cable tension increases, the tensioning and retracting frame cannot effectively buffer or balance the force, potentially causing the cable to become excessively slack in localized areas. Conversely, when cable tension decreases, it cannot provide sufficient additional tension to maintain the tension. This poor match between the tensioning and retracting frame and the cable tension results in the cable not being tightly arranged on the reel, but rather remaining loose. Loose cables not only occupy more storage space but may also cause tangling and knotting problems during subsequent handling and use, seriously affecting the quality and performance of the cable.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an automatic tensioning and retraction frame for preventing ship cables from tangling, comprising a base plate, on which a tensioning mechanism and a configuration mechanism are provided.

[0007] The tensioning mechanism includes a U-shaped rod module 1 fixedly connected to the top of the base plate. A motor is fixedly connected to the right side of the U-shaped rod module 1. The output shaft of the motor is fixedly connected to a rotating shaft 1 via a coupling. The rotating shaft 1 passes through the U-shaped rod module 1 and is rotatably connected to it. Two circular rings are fixedly sleeved on the outer wall of the rotating shaft 1. Two circular sliders are slidably sleeved on the outer wall of the rotating shaft 1. Several connecting rods are hinged to the inner walls of the two circular sliders. A tensioning ring is hinged to one end of each connecting rod away from the circular slider. Two outer springs are wound around the outer wall of the rotating shaft 1. One end of each outer spring is fixedly connected to the two circular rings, and the other end of each outer spring is fixedly connected to the two circular sliders.

[0008] Furthermore, an inner spring is wound around the outer wall of the rotating shaft, and the ends of the inner springs that are far apart from each other are fixedly connected to two circular sliders. Cables are wound around the outer walls of several tensioning rings.

[0009] Furthermore, the configuration mechanism includes a second U-shaped rod module fixedly connected to the top of the base plate. A reciprocating screw is rotatably connected to the inner wall of the second U-shaped rod module. The left and right ends of the reciprocating screw extend to the outside of the second U-shaped rod module and are rotatably connected to the second U-shaped rod module.

[0010] Furthermore, pulleys are fixedly sleeved on the outer walls of both the reciprocating screw and the rotating shaft, and belts are wound around the outer walls of the two pulleys.

[0011] Furthermore, the outer wall of the reciprocating screw is threaded with a sliding frame, the inner wall of the sliding frame is rotatably fitted with a guide roller, the outer wall of the guide roller is in contact with the cable, and the inner wall of the second U-shaped rod module is fixedly connected with a limiting rod, which passes through the sliding frame and is slidably connected to the sliding frame.

[0012] Furthermore, a U-shaped rod module three is fixedly connected to the top of the base plate, and a rotating shaft two is rotatably connected to the inner wall of the U-shaped rod module three. The right end of the rotating shaft two extends to the outside of the U-shaped rod module three and is rotatably connected to the U-shaped rod module three. A cleaning brush is fixedly sleeved on the outer wall of the rotating shaft two, and the cleaning brush is in contact with the cable.

[0013] Furthermore, pulleys are fixedly fitted on the outer walls of both the reciprocating screw and the rotating shaft, and belts are wound around the outer walls of the two pulleys.

[0014] This utility model has the following beneficial effects:

[0015] (1) By setting a tensioning mechanism, this utility model allows one end of the cable to pass through the sliding frame and be wound around multiple tensioning rings during use. Then, the motor is started, and the motor drives the rotating shaft one. Through two circular sliders and multiple connecting rods on the circular sliders, multiple tensioning rings can wind and reel in the cable on its outer wall. During the winding process, multiple tensioning rings can cooperate with two circular sliders and multiple connecting rods to compress and reset the two outer springs and inner springs on the outer wall of the rotating shaft one, thereby flexibly adjusting the tension force of the tensioning rings during winding and ensuring that the wound cable is tightly arranged on the reel.

[0016] (2) By setting up a configuration mechanism, when the rotating shaft rotates, the rotating shaft will also cooperate with the two pulleys and the belt to make the reciprocating screw rotate synchronously with the rotating shaft. When the reciprocating screw rotates, it will cooperate with the limiting rod so that the slide frame can cooperate with the guide roller to move the cable passing through it left and right, thereby evenly winding the cable on multiple tension rings and preventing concentrated winding from causing knots and tangles.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 As shown, this utility model is an automatic tensioning and retraction frame for preventing ship cables from tangling, including a base plate 1, on which a tensioning mechanism 2 and a configuration mechanism 3 are provided.

[0028] The tensioning mechanism 2 includes a U-shaped rod module 21 fixedly connected to the top of the base plate 1. A motor 22 is fixedly connected to the right side of the U-shaped rod module 21. The output shaft of the motor 22 is fixedly connected to a rotating shaft 23 via a coupling. The rotating shaft 23 passes through the U-shaped rod module 21 and is rotatably connected to it. Two circular rings 24 are fixedly sleeved on the outer wall of the rotating shaft 23, and two circular sliders 25 are slidably sleeved on the outer wall of the rotating shaft 23. The inner walls of the two circular sliders 25 are hinged with several connecting rods. A tensioning ring 27 is hinged to one end of a rod 26 away from the circular slider 25. Two outer springs 28 are wound around the outer wall of a rotating shaft 23. One end of each outer spring 28 is fixedly connected to two circular rings 24, and the other end of each outer spring 28 is fixedly connected to two circular sliders 25. An inner spring 29 is wound around the outer wall of the rotating shaft 23. The ends of the inner springs 29 that are far apart from each other are fixedly connected to two circular sliders 25. Cables 291 are wound around the outer wall of the tensioning rings 27.

[0029] By setting a tensioning mechanism, during use, one end of the cable 291 can be passed through the slide frame 35 and wound around multiple tensioning rings 27. Then, the motor 22 is started, which drives the rotating shaft 23. Through two circular sliders 25 and multiple connecting rods 26 on the circular sliders 25, the multiple tensioning rings 27 can wind and reel in the cable 291 on its outer wall. During the winding process, the multiple tensioning rings 27 can cooperate with the two circular sliders 25 and multiple connecting rods 26 to compress and reset the two outer springs 28 and inner springs 29 on the outer wall of the rotating shaft 23, thereby flexibly adjusting the tension force of the tensioning rings 27 during winding and ensuring that the wound cable 291 is tightly arranged on the reel.

[0030] Configuration mechanism 3 includes a U-shaped rod module 2 31 fixedly connected to the top of base plate 1. A reciprocating screw 32 is rotatably connected to the inner wall of the U-shaped rod module 2 31. The left and right ends of the reciprocating screw 32 extend outside the U-shaped rod module 2 31 and are rotatably connected to it. Pulleys 33 are fixedly fitted onto the outer walls of both the reciprocating screw 32 and the rotating shaft 23. Belts 34 are wound around the outer walls of the two pulleys 33. A sliding frame 35 is threaded onto the outer wall of the reciprocating screw 32. A guide roller 36 is rotatably fitted onto the inner wall of the sliding frame 35. The outer wall of the guide roller 36 is in contact with the cable 291. The U-shaped rod module 2 31... A limiting rod 37 is fixedly connected to the inner wall of the slide frame 35. The limiting rod 37 passes through the slide frame 35 and is slidably connected to the slide frame 35. A U-shaped rod module 38 is fixedly connected to the top of the base plate 1. A rotating shaft 39 is rotatably connected to the inner wall of the U-shaped rod module 38. The right end of the rotating shaft 39 extends to the outside of the U-shaped rod module 38 and is rotatably connected to the U-shaped rod module 38. A cleaning brush 391 is fixedly sleeved on the outer wall of the rotating shaft 39. The cleaning brush 391 is in contact with the cable 291. Pulleys 392 are fixedly sleeved on the outer walls of the reciprocating screw 32 and the rotating shaft 39. Belts 393 are wound around the outer walls of the two pulleys 392.

[0031] By setting up a configuration mechanism, when the rotating shaft 23 rotates, the rotating shaft 23 will also cooperate with the two pulleys 33 and the belt 34 to make the reciprocating screw 32 rotate synchronously with the rotating shaft 23. When the reciprocating screw 32 rotates, it will cooperate with the limiting rod 37 to make the sliding frame 35 cooperate with the guide roller 36 to move the cable 291 passing through it left and right, so as to evenly wind the cable 291 onto multiple tensioning rings 27 and prevent concentrated winding from causing knots and tangles.

[0032] A specific application of this embodiment is as follows: In use, one end of the cable 291 can be passed through the sliding frame 35 and wound around multiple tension rings 27. Then, the motor 22 is started, which drives the rotating shaft 23. Through two circular sliders 25 and multiple connecting rods 26 on the circular sliders 25, the multiple tension rings 27 can wind and reel in the cable 291 on its outer wall. During the winding process, the multiple tension rings 27 can cooperate with the two circular sliders 25 and multiple connecting rods 26 to compress and reset the two outer springs 28 and inner springs 29 on the outer wall of the rotating shaft 23, thereby flexibly adjusting the tension force of the tension rings 27 during winding, ensuring that the wound cable 291 is tightly arranged on the reel. At the same time, during the winding process of the multiple tension rings 27 driven by the two circular sliders 25, they will only slide on the outer wall of the rotating shaft 23 and will not rotate. Meanwhile, on the rotating shaft 23... 3. When rotating, the rotating shaft 23, through the cooperation of two pulleys 33 and belt 34, enables the reciprocating screw 32 to rotate synchronously with the rotating shaft 23. When the reciprocating screw 32 rotates, it cooperates with the limiting rod 37, so that the sliding frame 35 can cooperate with the guide roller 36 to move the cable 291 passing through it left and right, thereby evenly winding the cable 291 onto multiple tension rings 27, preventing knotting and tangling caused by concentrated winding. In addition, when the reciprocating screw 32 rotates, the reciprocating screw 32, through the cooperation of two pulleys 392 and belt 393, enables the rotating shaft 39 to rotate synchronously with the reciprocating screw 32. When the rotating shaft 39 rotates, it drives the cleaning brush 391 on it to clean the surface of the cable 291 that passes through, preventing the impurities remaining on the cable 291 from affecting the winding effect. The impurities after winding can fall and be collected in the collection box 394 for centralized treatment.
