Description

Technical Field

[0001] This utility model relates to the field of cable traction technology, and in particular to a cable traction device with a support mechanism. Background Technology

[0002] A cable traction device is a crucial piece of equipment in cable laying, relocation, or retrieval operations. It mainly consists of a traction power mechanism, a guiding mechanism, and a control system. The traction power mechanism, as the core power source, outputs strong force to overcome the friction and resistance encountered by the cable during traction, thus propelling the cable along a predetermined route. The guiding mechanism is responsible for guiding the cable in the correct direction, enabling it to smoothly traverse various complex environments, such as pipes and cable trays, and accurately reach the target location. The control system coordinates the orderly operation of all parts, ensuring a stable and efficient traction process. Due to its professional design and reliable performance, this device is widely used in many industries such as power, communications, and rail transportation, greatly improving the efficiency and quality of cable operations. Cable traction devices typically require the following technologies:

[0003] 1. High-efficiency traction power: To traction various types of cables, strong and stable power output is required, often using high-power motors or hydraulic drives. Motors are converted to high speed and high torque via a reduction mechanism, while hydraulic systems rely on pumps to generate high pressure to drive the motor. Power can be flexibly adjusted according to the actual cable traction conditions to ensure smooth and efficient traction.

[0004] 2. Precise guidance: The guiding mechanism guides the cable along the planned route. It is equipped with high-precision rollers or pulleys, and the surface is made of wear-resistant and low-friction polyurethane rubber to reduce friction, allowing the cable to pass through complex channels and bends smoothly, preventing damage to the outer sheath, and ensuring the cable is accurately positioned, thus improving the quality and efficiency of laying.

[0005] 3. Stable Control: The control system is crucial. Operators can set and adjust parameters such as traction speed and power on the control panel. The system accurately executes commands to ensure stable power delivery. The device is equipped with instrument indicator lights to display the operating status, allowing operators to react quickly in case of abnormalities. The system also features overload protection and emergency braking functions, enhancing equipment safety and reliability.

[0006] Currently, to realize the functions of cable traction devices, manufacturers have developed various applications in the power engineering field. These include the laying of long-distance high-voltage cables, precisely placing heavy cables into underground pipelines or overhead lines, significantly increasing the construction speed of power transmission lines. In communication network construction, they can quickly pull communication cables into buildings or underground communication pipelines, ensuring the rapid establishment and expansion of communication networks. For urban rail transit systems, they can lay large quantities of power and signal cables in the confined spaces along the tracks, ensuring stable power supply and signal transmission for subways, light rails, and other transportation vehicles. Furthermore, cable traction devices play a crucial role in the maintenance and replacement of cables in large industrial facilities, facilitating the retrieval of old cables and the pulling of new cables, reducing the difficulty and danger of manual operation, and improving the overall efficiency and quality of cable work.

[0007] However, the above method has a significant hardware structural problem: the cable may experience instability such as swaying and twisting. This instability is particularly pronounced during long-distance traction or when the cable is thick and heavy, making it prone to collisions and damage from surrounding objects. This application addresses this problem by proposing a solution: a clamping and conveying mechanism. The clamp firmly holds the cable, allowing it to move smoothly along a predetermined traction direction, preventing collisions or friction between the cable and surrounding objects such as pipe walls and cable tray edges, thereby reducing the risk of damage to the cable sheath. Utility Model Content

[0008] To address the shortcomings of existing technologies, this invention provides a cable traction device with a support mechanism, solving the problem of cable instability such as swaying and twisting. This instability is particularly pronounced during long-distance traction or when the cable is heavy, making it prone to collisions and damage from surrounding objects.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A cable traction device with a support mechanism includes a traction device body, a placement seat fixedly connected to the lower surface of the traction device body, and a clamping and conveying mechanism, including a placement frame, a U-shaped plate and two clamps. The lower surface of the placement frame is fixedly connected to the upper surface of the placement seat. The placement frame has an internal hollow structure. Two sliding grooves are opened through the upper surface of the placement frame. The U-shaped plate is located inside the placement frame. The lower surfaces of the two clamps are movably connected to the upper surface of the placement frame. Springs are fixedly connected to the opposite sides of the two clamps. The upper end of the U-shaped plate passes through the two sliding grooves and is fixedly connected to the corresponding springs.

[0011] Preferably, both ends of the U-shaped plate are provided with movable discs, and two circular holes are opened through the left and right sides of the U-shaped plate. Movable rods are fixedly connected to the opposite sides of the two clamps, and the two movable rods pass through the circular holes and are fixedly connected to the corresponding movable discs.

[0012] Preferably, the placement frame has a movable plate inside, the upper surface of which is fixedly connected to the lower surface of the U-shaped plate, and a screw is installed inside the placement frame, with both ends of the screw being rotatably connected to the inner wall of the placement frame.

[0013] Preferably, the front surface of the movable plate is provided with a threaded groove, and the movable plate is threadedly connected to the screw through the threaded groove. Guide rods are provided at both ends of the screw, and the front and rear ends of the two guide rods are rotatably connected to the inner wall of the placement frame.

[0014] Preferably, the front surface of the movable plate has two through holes corresponding to the positions of the guide rods, and the movable plate is movably connected to the corresponding guide rods through the two through holes. The rear surface of the placement frame has a through hole.

[0015] Preferably, a connecting ring is fixedly connected to the rear surface of the placement frame, and a motor is fixedly connected to the rear surface of the connecting ring. The output port of the motor passes through a circular hole and is fixedly connected to the rear surface of the screw.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The operator moves the two clamps, compressing the two springs. One end of the cable is placed between the two clamps. The clamps are then released, and the two springs return, clamping the cable end. The motor is then started, driving the screw to rotate. Because the moving plate is limited by the two guide rods, it does not rotate with the screw. Instead, the moving plate moves forward. Since the U-shaped plate is fixedly connected to the moving plate, and the two clamps and the cable are on the U-shaped plate, the movement of the moving plate will cause the cable U-shaped plate to move until the cable end contacts the main body of the traction device, thus achieving the purpose of installing the cable onto the main body of the traction device. The clamps can firmly hold the cable, allowing it to move smoothly along the predetermined traction direction, avoiding collisions or friction between the cable and surrounding objects such as pipe walls and cable tray edges, thereby reducing the risk of damage to the cable sheath.

[0018] 2. When the two clamps are released, the two springs will push the clamps to move relative to each other. When the two clamps move, they will drive the corresponding moving rods and moving discs to move. When the moving discs move a certain distance, the two moving discs will be blocked by the corresponding U-shaped plates, which avoids the problem of the two clamps colliding due to the two springs pushing the clamps too much.

[0026] This application provides a cable traction device with a support mechanism, which effectively solves the problem of cable swaying, twisting, and other instability. This instability is particularly pronounced during long-distance traction or when the cable is heavy and thick, making it prone to collisions and damage. To address this, the operator moves two clamps, compressing two springs. One end of the cable is placed between the clamps, and the clamps are released, causing the springs to spring back and clamp the cable end. The motor is then started, driving the screw to rotate. Because the moving plate is limited by two guide rods, it does not rotate with the screw but moves forward. Since the U-shaped plate is fixedly connected to the moving plate, and the two clamps and cable are on the U-shaped plate, the movement of the moving plate moves the cable U-shaped plate until the cable end contacts the main body of the traction device, thus installing the cable onto the device. The clamps firmly hold the cable, allowing it to move smoothly along the predetermined traction direction, preventing collisions or friction with surrounding objects such as pipe walls and cable tray edges, thereby reducing the risk of cable sheath damage. Example

[0027] The technical solution in this application effectively addresses the instability issues that cables may experience, such as swaying and twisting. This instability is particularly pronounced during long-distance traction or when the cable is heavy or thick, making it prone to collisions and damage. The overall approach is as follows:

[0028] To address the problems existing in the prior art, this utility model provides a cable traction device with a support mechanism, including a traction device body 10. A placement seat 11 is fixedly connected to the lower surface of the traction device body 10. The cable traction device with the support mechanism also includes a clamping and conveying mechanism, including a placement frame 12, a U-shaped plate 16, and two clamps 18. The lower surface of the placement frame 12 is fixedly connected to the upper surface of the placement seat 11. The placement frame 12 has an internal hollow structure. Two sliding grooves 14 are formed through the upper surface of the placement frame 12. The U-shaped plate 16 is located inside the placement frame 12. The lower surfaces of the two clamps 18 are movably connected to the upper surface of the placement frame 12. Springs 26 are fixedly connected to the opposite sides of the two clamps 18. The upper end of the U-shaped plate 16 passes through the two sliding grooves 14 and engages with the corresponding... Spring 26 is fixedly connected. Both ends of U-shaped plate 16 are provided with movable discs 15. Two circular holes 27 are opened through the left and right sides of U-shaped plate 16. Movable rods 25 are fixedly connected to the opposite sides of the two clamps 18. The two movable rods 25 pass through the circular holes 27 and are fixedly connected to the corresponding movable discs 15. When the operator moves the two clamps 18, the two springs 26 are compressed. One end of the cable is placed between the two clamps 18. When the clamps 18 are released, the two springs 26 rebound, so that the two clamps 18 clamp the end of the cable. At this time, the motor 13 is started. The motor 13 drives the screw 19 to rotate. Since the movable plate 21 is limited by the two guide rods 20, the movable plate 21 will not rotate with the rotation of the screw 19, and the movable plate 21 will move forward.

[0029] A movable plate 21 is provided inside the placement frame 12. The upper surface of the movable plate 21 is fixedly connected to the lower surface of the U-shaped plate 16. A screw 19 is provided inside the placement frame 12. Both ends of the screw 19 are rotatably connected to the inner wall of the placement frame 12. A threaded groove 23 is provided through the front surface of the movable plate 21. The movable plate 21 is threadedly connected to the screw 19 through the threaded groove 23. Guide rods 20 are provided at both ends of the screw 19. Both ends of the two guide rods 20 are rotatably connected to the inner wall of the placement frame 12. The U-shaped plate 16 is fixedly connected to the movable plate 21, and the two clamps 18 and the cable are on the U-shaped plate 16. Therefore, the movement of the movable plate 21 will drive the cable U-shaped plate 16 to move until the end of the cable contacts the main body 10 of the traction device, so as to achieve the purpose of installing the cable onto the main body 10 of the traction device. The clamps 18 can firmly hold the cable and make it move smoothly along the predetermined traction direction, avoiding collisions or friction between the cable and surrounding objects such as pipe walls, cable tray edges, etc., thereby reducing the risk of damage to the cable sheath.

[0030] Two circular holes 24, corresponding to the positions of the guide rods 20, are provided through the front surface of the movable plate 21. The movable plate 21 is movably connected to the corresponding guide rods 20 through the two circular holes 24. A circular hole 22 is provided through the rear surface of the placement frame 12. A connecting ring 17 is fixedly connected to the rear surface of the placement frame 12. A motor 13 is fixedly connected to the rear surface of the connecting ring 17. The output port of the motor 13 is fixedly connected to the rear surface of the screw 19 through the circular hole 22. When the two clamps 18 are released, the two springs 26 will push the clamps 18 to move relative to each other. When the two clamps 18 move, they will drive the corresponding movable rods 25 and movable discs 15 to move. When the movable discs 15 move a certain distance, the two movable discs 15 will be blocked by the corresponding U-shaped plates 16, which avoids the problem of the two clamps 18 colliding due to the two springs 26 pushing the clamps 18 too much.

[0031] Working principle:

[0032] The operator moves the two clamps 18, compressing the two springs 26. One end of the cable is placed between the two clamps 18. The clamps 18 are then released, and the two springs 26 spring back, clamping the cable end between the clamps 18. The motor 13 is then started, driving the screw 19 to rotate. Because the moving plate 21 is limited by the two guide rods 20, it does not rotate with the screw 19. Instead, the moving plate 21 moves forward. Since the U-shaped plate 16 is fixedly connected to the moving plate 21, and the two clamps 18 and the cable are on the U-shaped plate 16, the movement of the moving plate 21 will cause the cable U-shaped plate 16 to move until the cable end is aligned with the main traction device. When the two clamps 18 come into contact with the main body 10, the cable is installed onto the main body 10 of the traction device. The clamps 18 can firmly hold the cable and make it move smoothly along the predetermined traction direction, avoiding collisions or friction between the cable and surrounding objects such as pipe walls and cable tray edges, thereby reducing the risk of damage to the cable sheath. When the two clamps 18 are released, the two springs 26 will push the clamps 18 to move relative to each other. When the two clamps 18 move, they will drive the corresponding moving rods 25 and moving discs 15 to move. When the moving discs 15 move a certain distance, the two moving discs 15 will be blocked by the corresponding U-shaped plates 16, avoiding the problem of the two clamps 18 colliding due to excessive pushing of the two springs 26.

[0033] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
