Description

Technical Field

[0001] This utility model relates to the technical field of cable traction devices, and in particular to a cable traction device for cable laying. Background Technology

[0002] Cable traction devices are crucial equipment in cable laying projects, ensuring the smooth pulling of cables from the starting point to the target location. This technology significantly improves the efficiency and quality of cable laying, reducing labor costs and construction time. Compared to traditional cable laying methods, it offers undeniable advantages. It can precisely control the traction force and speed, preventing excessive stretching or friction during the traction process, thus protecting the cable's integrity and performance. Furthermore, it is adaptable to different types and specifications of cables, from thick to thin, enabling efficient traction and laying, enhancing the versatility and flexibility of the project, and bringing convenience to cable laying projects.

[0003] In existing cable laying operations, a relatively traditional traction device is typically used. This device generally consists of a motor, a transmission mechanism, a traction wheel, and a fixing frame. During operation, the motor drives the traction wheel to rotate via the transmission mechanism. The cable is placed on the traction wheel, and as the traction wheel rotates, the cable is slowly pulled forward. Throughout the process, the fixing frame supports and stabilizes the entire device, ensuring that it does not sway or shift during operation. This workflow can be effective in some simple, straight cable laying scenarios, and can basically complete the cable traction task.

[0004] However, existing cable traction devices have a problem: adjusting the distance between the two traction shafts often requires complex operations such as disassembling and reassembling nuts. This adjustment method is cumbersome, not only consuming a lot of time, but also easily causing the loss or damage of parts during repeated disassembly and reassembly of nuts, further affecting the normal use and adjustment accuracy of the device. This reduces work efficiency and increases construction costs and difficulty when the traction shaft distance needs to be frequently adjusted to adapt to different cable specifications. Therefore, a cable traction device for cable laying is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a cable traction device for cable laying, which aims to improve the problem that the adjustment process of adjusting the distance between the two traction shafts usually requires the removal of nuts, which is quite cumbersome.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cable traction device for cable laying includes a base plate, a winding shaft fixedly connected to one side of the top of the base plate, a traction machine fixedly connected to the other side of the top of the base plate, multiple traction shafts on both sides of the traction machine, a support column fixedly connected to both ends of each traction shaft, an adjustment component on the outer wall of the support column, and a traction component on one side of the traction machine.

[0008] The adjustment assembly includes multiple arc-shaped clamps. The inner walls of the adjacent arc-shaped clamps are all set on the outer wall of the support column. Support blocks are fixedly connected to both sides of the top of the traction machine. A fixing block is fixedly connected to the inner wall of each support block. A connecting shaft is rotatably connected inside each fixing block. Each connecting shaft is rotatably connected to the inside of the arc-shaped clamps on both sides. Multiple rubber pads are fixedly connected to the outer wall of each arc-shaped clamp. The rubber pads are fixedly connected to the inner wall of the fixing block. Multiple springs are provided on the outer wall of each arc-shaped clamp. One end of each spring is fixedly connected to the outer wall of the arc-shaped clamp, and the other end of each spring is fixedly connected to the inner wall of the fixing block.

[0009] As a further description of the above technical solution:

[0010] The traction assembly includes multiple traction wheels, which are located on one side of the traction machine, and a connecting shell is fixedly connected to the top of the base plate;

[0011] As a further description of the above technical solution:

[0012] The bottom of the base plate is fixedly connected to multiple moving wheels, the top of the base plate is fixedly connected to a handle, and one end of each support column is fixedly connected to a fixing ring;

[0013] As a further description of the above technical solution:

[0014] Multiple rotating shafts are slidably connected to the top of the inner wall of the connecting shell, and each rotating shaft is rotatably connected inside the traction wheel.

[0015] As a further description of the above technical solution:

[0016] Each of the rotating shafts is fixedly connected to a connecting plate at its bottom end, and the connecting plate is located at the bottom of the inner wall of the connecting shell;

[0017] As a further description of the above technical solution:

[0018] The connecting shell has multiple slots inside, and each connecting plate has a sliding plate slidably connected to both sides inside.

[0019] As a further description of the above technical solution:

[0020] Each of the slide plates is fixedly connected to a movable plate at one end, and springs are fixedly connected between adjacent slide plates on both sides.

[0021] As a further description of the above technical solution:

[0022] Each of the aforementioned skateboards has a fixedly connected card plate at its bottom, and the card plate engages with the card slot.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the support columns at both ends of the traction shaft are engaged by the arc-shaped clamps on both sides, and the reaction force of the spring is used to enhance the fixing effect of the arc-shaped clamps on the support columns. This solves the problem that the nuts usually need to be disassembled and the adjustment process is cumbersome when adjusting the distance between the two traction shafts, and enhances the portability of adjusting the distance between the two traction shafts.

[0025] 2. In this utility model, by pushing the traction wheel on the outer wall of the rotating shaft to move left or right, the cable can be moved to the left or right.

[0033] 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.

[0034] Reference Figure 1 - Figure 4 The present invention provides an embodiment of a cable traction device for cable laying, comprising a base plate 1, a winding shaft 2 fixedly connected to one side of the top of the base plate 1, the winding shaft 2 being made of high-strength alloy steel with a special wear-resistant treatment on its surface to ensure that no wear occurs during long-term cable unwinding, and a precision bearing structure inside to make rotation smoother and thus stably unwind the cable; a traction machine 3 fixedly connected to the other side of the top of the base plate 1, and multiple traction shafts 5 on both sides of the traction machine 3, each traction shaft 5 having a support column 6 fixedly connected to both ends; the support column 6 is a solid cylindrical structure made of high-quality stainless steel, which has good strength and corrosion resistance and can withstand greater pressure; an adjustment component is provided on the outer wall of the support column 6; and a traction component is provided on one side of the traction machine 3.

[0035] The adjustment assembly includes multiple arc-shaped clamps 10. The inner walls of adjacent arc-shaped clamps 10 are set on the outer walls of the support columns 6. The arc-shaped clamps 10 are made of high-strength aluminum alloy, a material that is both lightweight and strong enough to withstand pressure. Their arc shape is precisely cast using molds to ensure the accuracy of their fit with the support columns 6 and other components. Support blocks 4 are fixedly connected to both sides of the top of the traction machine 3. A fixing block 7 is fixedly connected to the inner wall of each support block 4. A connecting shaft 11 is rotatably connected inside each fixing block 7. Each connecting shaft 11 is rotatably connected to the arc-shaped clamps on both sides. Inside the base plate 10, multiple rubber pads 8 are fixedly connected to the outer wall of each arc-shaped clamp 10. These rubber pads 8 are made of high-quality wear-resistant rubber and fit tightly against the outer wall of the arc-shaped clamp 10. This rubber has good elasticity and wear resistance, effectively protecting the outer wall of the arc-shaped clamp 10 and preventing damage during compression and rotation. The rubber pads 8 are fixedly connected to the inner wall of the fixing block 7. Multiple springs 9 are provided on the outer wall of each arc-shaped clamp 10. One end of each spring 9 is fixedly connected to the outer wall of the arc-shaped clamp 10, and the other end is fixedly connected to the inner wall of the fixing block 7. Multiple moving wheels 22 are fixedly connected to the bottom of the base plate 1, and a handle 21 is fixedly connected to the top of the base plate 1. A fixing ring 23 is fixedly connected to one end of each support column 6.

[0036] Specifically, during the cable pulling process, the distance between the two pulling shafts 5 needs to be adjusted to accommodate cables of different thicknesses. This is because different cables have different diameters. If the distance between the pulling shafts 5 remains fixed, it will be impossible to properly pull cables of various specifications. In the specific process of adjusting the distance between the two pulling shafts 5, the support columns 6 at both ends of the pulling shafts 5 need to be moved to the inner wall of one of the arc-shaped clamps 10. When the outer wall of the support column 6 contacts the inner wall of the arc-shaped clamp 10, the arc surface of the outer wall of the support column 6 will press against the arc-shaped clamps 10 on both sides. Under the pressing action of the support column 6, the arc-shaped clamps 10 will rotate in the opposite direction around the connecting shaft 11. As the arc-shaped clamp 10 rotates, it compresses the rubber pad 8 and the spring 9. When the support column 6 is in contact with the bottom of the inner wall of the arc-shaped clamp 10, the top of the arc-shaped clamp 10 on both sides loses the compression of the outer diameter of the support column 6. At this time, the reaction force of the spring 9 pushes the arc-shaped clamp 10 to lock and fix the outer wall of the support column 6. By moving the support columns 6 on both sides of the traction shaft 5 to the inner wall of the arc-shaped clamp 10 at different positions, the position of the traction shaft 5 can be flexibly adjusted, which enhances the convenience of the traction shaft 5 adjustment process and improves the versatility and working efficiency of the equipment.

[0037] Reference Figure 2 and Figure 5The traction assembly includes multiple traction wheels 14, each made of polyurethane rubber wrapped around a metal hub. Polyurethane rubber offers high wear resistance, high elasticity, and good grip. The traction wheels 14 are located on one side of the traction machine 3. A connecting shell 12 is fixedly connected to the top of the base plate 1. Multiple rotating shafts 13 are slidably connected to the top of the inner wall of the connecting shell 12. Each rotating shaft 13 is rotatably connected to the inside of the traction wheel 14. A connecting plate 15 is fixedly connected to the bottom of each rotating shaft 13. The connecting plate 15 is located at the bottom of the inner wall of the connecting shell 12. Multiple slots 20 are provided inside the connecting shell 12. Sliding plates 17 are slidably connected to both sides of each connecting plate 15. A movable plate is fixedly connected to one end of each sliding plate 17. The movable plate 16 is made of high-strength engineering plastic with a frosted surface, which not only provides a good tactile feel but also effectively prevents the operator from slipping when pressing. Its internal structure is designed as a honeycomb, which reduces its weight while ensuring strength. Springs 19 are fixedly connected between adjacent sliding plates 17. Each sliding plate 17 has a locking plate 18 fixedly connected to its bottom. The locking plate 18 is made of wear-resistant stainless steel. Its front end is designed with a slightly inclined guide surface to facilitate smooth entry and exit from the slot 20 during movement. The rear end has a thickened part to better lock into the slot 20 under the action of springs 19. The locking plate 18 and the slot 20 are engaged.

[0038] Specifically, during cable laying, when the cable needs to be pulled in different directions, firstly, by pressing the movable plates 16 on both sides, the sliding plate 17 is driven to slide inside the connecting plate 15. During the movement of the sliding plate 17, the spring 19 is squeezed. At the same time, the movement of the sliding plate 17 will cause the locking plate 18 to slide out from the inner wall of the slot 20. Then, the traction wheel 14 on the outer wall of the rotating shaft 13 is slid to the left or right. When the traction wheel 14 moves to the appropriate position, the squeezing force on the movable plate 16 is released, and the rebound force of the spring 19 pushes the locking plate 18 to re-lock into the inner wall of the slot 20, thereby fixing the position of the traction wheel 14 after it has moved. By moving the two traction wheels 14 to the left or right, the cable is pulled to the left or right, meeting different traction needs and enhancing the applicability of the equipment.

[0039] Working Principle: During operation, the cable is first unwound using the take-up shaft 2, and then pulled by the traction machine 3. During cable pulling, the distance between the two traction shafts 5 needs to be adjusted to accommodate cables of different thicknesses. While adjusting the distance, the support columns 6 at both ends of the traction shafts 5 are moved to the inner wall of one of the arc-shaped clamping plates 10. The arc surface of the outer wall of the support column 6 presses against the arc-shaped clamping plates 10 on both sides, causing them to rotate in opposite directions around the connecting shaft 11. As the arc-shaped clamping plates 10 rotate, they press against the rubber pad 8 and spring 9. The rubber pad 8 protects the outer wall of the arc-shaped clamping plate 10. When the support column 6 is against the bottom of the inner wall of the arc-shaped clamping plate 10, the top of the arc-shaped clamping plates 10 loses the pressure from the outer diameter of the support column 6. The reaction force of the spring 9 then pushes the arc-shaped clamping plates 10 to lock against the outer wall of the support column 6. The position is fixed. By moving the support columns 6 on both sides of the traction shaft 5 to the inner wall of the arc-shaped clamping plate 10 at different positions, the position of the traction shaft 5 can be adjusted, enhancing the portability of the traction shaft 5 during adjustment. When the cable needs to be pulled in different directions, by pressing the movable plates 16 on both sides, the sliding plate 17 is driven to slide inside the connecting plate 15. During the movement, the sliding plate 17 will squeeze the second spring 19 and slide the clamping plate 18 out of the inner wall of the slot 20. Then, the traction wheel 14 on the outer wall of the rotating shaft 13 will slide to the left or right. When the traction wheel 14 moves to the appropriate position, the squeezing force on the movable plate 16 is released, and the rebound force of the second spring 19 pushes the clamping plate 18 to be clamped back into the inner wall of the slot 20, thus fixing the position of the traction wheel 14 after movement. By moving the two traction wheels 14 to the left or right, the cable can be pulled to the left or right to meet different traction needs and enhance the applicability of the equipment.

[0040] 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.
