Description

Technical Field

[0001] This utility model relates to the field of marine engineering equipment technology, and in particular to a cable traction device for marine engineering. Background Technology

[0002] Marine engineering refers to new construction, reconstruction, and expansion projects aimed at developing, utilizing, protecting, and restoring marine resources, with the main body of the project located on the seaward side of the coastline. In marine engineering, cable pulling devices are commonly used equipment for laying and retrieving cables such as electric cables and steel cables. Publication No. CN216736949U discloses a cable pulling device for marine engineering, including a left mounting plate and a right mounting plate. A slot is formed at the center of the top of the left mounting plate, and a layered assembly is movably installed inside the slot. A winding roller is movably installed on the opposite side of the left and right mounting plates via bearings. This utility model utilizes a combination of a left mounting plate, a right mounting plate, a drive gear, a drive motor, a connecting rod, a driven gear, a servo motor, a lead screw, a mounting frame, an eccentric handwheel, a hexagonal protrusion, a screw, a clamping assembly, a slot, a hexagonal slot, a wire guide plate, a stepper motor, and an auxiliary plate. This design offers the advantage of rapid cable organization and solves the problem of existing traction equipment being unable to perform layered processing of wound cables and lacking wire organization functions, resulting in messy cables prone to tangling and knotting. Furthermore, this equipment cannot maintain a uniform distribution of the cable on the surface of the take-up roller during cable winding and unwinding, easily leading to uneven winding and overlapping during take-up, causing problems for subsequent use and affecting the normal winding and unwinding of cables. Therefore, improvements are needed. Utility Model Content

[0003] The purpose of this utility model is to solve the technical problems mentioned in the background art.

[0004] This utility model adopts the following technical solution: a cable traction device for marine engineering, including a base plate, a side plate and a limiting plate fixedly installed on the surface of the base plate, a traction motor fixedly installed on the surface of one of the side plates, a cable roller fixedly installed at the output end of the traction motor, a guide roller rotatably connected to the surface of the side plate, a sliding rod fixedly installed on the surface of both the limiting plate and the side plate, a first motor fixedly installed on the surface of one of the limiting plates, a first threaded rod fixedly installed at the output end of the first motor, a guide block threadedly connected to the surface of the first threaded rod, a limiting rod and a first spring fixedly installed inside the guide block, a rotating shaft fixedly installed at one end of the first spring, and a guide wheel rotatably connected to the surface of the rotating shaft.

[0005] Preferably, the cable roller is rotatably connected to the side plate, and the guide block is slidably connected to the slide rod. Here, the sliding connection between the guide block and the slide rod, with the base plate and the slide rod providing support for the guide block, ensures that the guide block moves smoothly along the axis of the slide rod. This allows the position of the cable on the surface of the cable roller to be changed when the cable is being retrieved or pulled, so that the cable is evenly wound on the surface of the cable roller.

[0006] Preferably, the limiting rod and guide block are slidably connected to the rotating shaft. Here, the rotating shaft slides inside the guide block and on the surface of the limiting rod, allowing the rotating shaft to move flexibly along the axial direction of the limiting rod. In conjunction with the first spring, the rotating shaft can adaptively adjust its position by sliding when winding or unwinding cables of different diameters or when subjected to lateral impacts from waves. This ensures that the guide wheel is always in contact with the cable surface, avoiding slippage due to excessively loose clamping or cable damage due to excessively tight clamping, which could affect subsequent traction or winding operations.

[0007] Preferably, the rotating shaft and guide wheels are symmetrically distributed inside the guide block. This symmetrical distribution allows for the application of balanced clamping force from both sides of the cable, preventing offset or bending caused by unilateral force. Furthermore, the symmetrically distributed guide wheels disperse the reaction force of the cable on the guide wheels, reducing wear on one side of the guide wheels, extending their service life, ensuring stability during traction or retrieval, reducing the risk of cable entanglement or jamming, and improving the stability of the device.

[0008] Preferably, a second motor is fixedly mounted on the top of the side plate, a second threaded rod is fixedly mounted on the output end of the second motor, a movable plate is threadedly connected to the surface of the second threaded rod, a second spring is fixedly mounted on the surface of the movable plate, an mounting block is fixedly mounted on one end of the second spring, and an adjusting roller is rotatably connected to the surface of the mounting block. Here, the second motor drives the second threaded rod to raise and lower the movable plate, which can adjust the distance between the cable roller and the guide roller and the adjusting roller, adapting to the traction requirements of cables of different materials, and maintaining the tension of the cable when winding or pulling the cable. The second spring provides elastic buffer for the mounting block and the adjusting roller, preventing the cable from breaking due to rigid stress caused by instantaneous tension due to waves or other reasons during cable winding and unwinding.

[0009] Preferably, the movable plate and mounting block are slidably connected to the side plate. Here, the movable plate and mounting block slide on the inner surface of the side plate, ensuring that the adjusting roller always moves in the vertical direction of the side plate, avoiding uneven cable tension caused by the movable plate or mounting block shifting during movement, which would affect the cable winding or pulling.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] 1. In this utility model, the base plate, side plate, limiting plate, traction motor, cable roller, guide roller, slide bar, first motor, first threaded rod, and guide block enable the guide block to reciprocate along the horizontal axis of the slide bar, allowing the cable to smoothly, orderly, and evenly wind around the cable roller on the guide roller surface. This prevents uneven winding and misalignment of the cable on the cable roller surface from affecting subsequent traction or winding operations. The limiting rod, first spring, rotating shaft, and guide wheel ensure that the guide wheel remains in contact with the cable surface when winding or pulling cables of different materials and diameters, preventing slippage due to excessively loose clamping or cable damage due to excessively tight clamping, which could affect the subsequent use of the device.

[0012] 2. In this utility model, the second motor, second threaded rod, moving plate, second spring, mounting block and adjusting roller can change the position of the adjusting roller to provide stable and uniform tension and pulling force for the cable. This ensures that the cable remains taut during winding or pulling while having sufficient elasticity to prevent the cable from breaking due to sudden changes in external force. It also allows the wire to be continuously and evenly wound on the cable roller, improving the winding efficiency and the stability of the device. Attached Figure Description

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1

[0022] Please see Figure 1-2 This utility model provides a technical solution: a cable traction device for marine engineering, including a base plate 1, a side plate 2 and a limiting plate 3 fixedly installed on the surface of the base plate 1, a traction motor 4 fixedly installed on the surface of one of the side plates 2, a cable roller 5 fixedly installed at the output end of the traction motor 4, a guide roller 6 rotatably connected to the surface of the side plate 2, a sliding rod 7 fixedly installed on the surface of both the limiting plate 3 and the side plate 2, a first motor 8 fixedly installed on the surface of one of the limiting plates 3, a first threaded rod 9 fixedly installed at the output end of the first motor 8, and so on. A guide block 10 is threadedly connected to the surface of a threaded rod 9. A limit rod 11 and a first spring 12 are fixedly installed inside the guide block 10. A rotating shaft 13 is fixedly installed at one end of the first spring 12. A guide wheel 14 is rotatably connected to the surface of the rotating shaft 13. The cable roller 5 is rotatably connected to the side plate 2. The guide block 10 is slidably connected to the slide rod 7. The base plate 1 and the slide rod 7 provide support for the guide block 10, ensuring that the guide block 10 moves smoothly along the axis of the slide rod 7, and can adjust its position when retrieving or pulling cables. The position of the cable on the surface of the cable roller 5 is adjusted to ensure the cable is evenly wound on the surface of the cable roller 5. The limiting rod 11 and the guide block 10 are slidably connected to the rotating shaft 13. The rotating shaft 13 slides inside the guide block 10 and on the surface of the limiting rod 11, allowing the rotating shaft 13 to move flexibly along the axial direction of the limiting rod 11. In conjunction with the first spring 12, the rotating shaft 13 can adaptively adjust its position by sliding when winding and unwinding cables of different diameters or when subjected to lateral impacts from waves, ensuring that the guide wheel 14 is always in contact with the cable surface, avoiding slippage due to excessively loose clamping or slippage due to excessively tight clamping. Cable damage affects subsequent traction or reeling operations. The symmetrical distribution of the shaft 13 and guide wheel 14 inside the guide block 10 allows for the application of balanced clamping force from both sides of the cable, preventing offset or bending caused by unilateral force. Furthermore, the symmetrically distributed guide wheel 14 can disperse the reaction force of the cable on the guide wheel, reducing wear on one side of the guide wheel, extending its service life, ensuring the stability of the traction or reeling process, reducing the risk of cable entanglement or jamming, and improving the stability of the device.

[0023] Example 2

[0024] Please see Figure 3-4 A second motor 15 is fixedly installed at the top of the side plate 2. A second threaded rod 16 is fixedly installed at the output end of the second motor 15. A movable plate 17 is threadedly connected to the surface of the second threaded rod 16. A second spring 18 is fixedly installed on the surface of the movable plate 17. A mounting block 19 is fixedly installed at one end of the second spring 18. An adjusting roller 20 is rotatably connected to the surface of the mounting block 19. The second motor 15 drives the second threaded rod 16 to move the movable plate 17 up and down, which can adjust the distance between the cable roller 5 and the guide roller 6 and the adjusting roller 20, and can adapt to the traction requirements of cables of different materials. The second spring 18 provides elastic buffer for the mounting block 19 and the adjusting roller 20 to maintain the tension of the cable when winding or pulling it. This prevents the cable from breaking due to rigid force caused by instantaneous tension due to waves or other reasons when winding or unwinding the cable. The moving plate 17 and the mounting block 19 are slidably connected to the side plate 2. The moving plate 17 and the mounting block 19 slide on the inner surface of the side plate 2 to ensure that the adjusting roller 20 always moves in the vertical direction of the side plate 2. This prevents the uneven tension of the cable from affecting the winding or pulling of the cable due to the deviation of the moving plate 17 or the mounting block 19 during movement.

[0025] Working principle: During the traction and cable laying operation, one end of the cable is pulled out from the surface of the cable roller 5, then passes through the bottom surface of the rear guide roller 6 and the upper surface of the adjusting roller 20, then through the bottom surface of the front guide roller 6, and finally through the guide block 10. The cable is placed in the gap between the two guide wheels 14. The cable will squeeze the guide wheel 14, causing the rotating shaft 13 to slide inside the guide block 10 and on the surface of the limiting rod 11, compressing the first spring 12, ensuring that the guide wheel 14 is always in contact with the cable surface. The second motor 15 is started to drive the second threaded rod 16 to rotate, adjusting the moving plate 1. 7. The second spring 18 and the mounting block 19 are positioned on the inner surface of the side plate 2. Adjust the tension of the cable. Finally, start the traction motor 4 to rotate the cable and pull it through the guide roller 6, the adjusting roller 20 and the guide block 10 to complete the cable release. When it is necessary to retract the cable, start the first motor 8 and reverse the traction motor 4. The first motor 8 drives the first threaded rod 9 to rotate and make the guide block 10 slide on the surface of the slide rod 7, so that the cable is evenly retracted and wound on the surface of the cable roller 5. After the cable is retracted, turn off the first motor 8, the second motor 15 and the traction motor 4.
