[0002] A cable is a conductor assembly used to transmit electrical energy or signals. It typically consists of one or more mutually insulated conductors (cores) and an outer protective layer. It is an indispensable infrastructure in modern power systems and communication networks, and is widely used in power transmission, communication, data transmission, industrial control and other fields.

[0003] Cable damage protection external structures refer to components or devices installed on the outside of cables to enhance their mechanical strength, protective performance, and durability. They are usually made by wrapping a metal wire braid or metal strip around the conductor or insulation layer inside the cable.

[0004] In the current technology, the friction between the cable and the pipe is relatively large during the cable laying process, which makes the cable movement difficult, the laying speed slow, and affects the project progress. During the laying process, the cable is easily affected by external friction, impact and vibration, which leads to wear and damage to the outer wall of the cable, affecting the service life and safety of the cable. Utility Model Content

[0005] In order to overcome the problem that the existing cables have high friction during the laying process, which makes them difficult to move and slows down the laying speed, an external structure for cable damage prevention was proposed.

The lower end of the lower clamping frame is fixedly connected to the connecting column. The outer wall of the connecting column is slidably equipped with a sliding cylinder. The lower end of the sliding cylinder is fixedly connected to the fixed plate. The outer wall of the sliding cylinder is fitted with a spring for shock absorption. The other end of the spring is fixedly connected to the lower end of the lower clamping frame. The outer wall of the fixed plate is fixedly equipped with a protective ring for protection. The protective ring is located outside the spring. The front and rear ends of the fixed plate are rotatably equipped with second pulleys.

[0007] Preferably, the fastener includes a stud, a rubber clamp, and a rotating ring. The stud is threaded onto the first or second threaded groove, the lower end of the stud is rotatably fitted with a rubber clamp, and the stud is rotatably fitted with a rotating ring.

[0008] Preferably, a cable is placed at the center of the upper and lower clamping frames, close to each other, with the outer wall of the cable fitting against one end of each of the three rubber clamps.

[0009] Preferably, a connecting arc block is fixed to the upper end of the fixing plate, and the lower end of the lower clamping frame is fixed to the other end of the connecting arc block.

[0010] Preferably, a first baffle is fixed to the left end of the lower clamping frame, and two second baffles are fixed to the right end of the first baffle, with the two second baffles located around the protective ring.

[0011] Preferably, the integrated structure formed by the first baffle and the lower clamping frame has a first groove, and the right end of the lower clamping frame has a second groove, with the first groove and the second groove communicating with each other.

[0012] Preferably, the fixing plate is arc-shaped and made of a high-toughness material.

[0013] The beneficial effects of this utility model are as follows: During the installation process, the cable is clamped by fasteners, and then the traction device is activated to drag the cable on the device by passing the traction line through the displacement member. During the cable laying process, when encountering bends and uneven areas, the two first pulleys and two second pulleys on the cable reduce the external friction experienced by the cable during sliding. Through the vibration damping structure formed by the fixed plate, connecting column / slide cylinder and spring, it can overcome small obstacles and improve the overall efficiency of pipeline laying.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-5 This utility model provides an embodiment of a cable damage prevention external structure, including an upper clamping frame 1, fasteners, and a displacement component. A lower clamping frame 6 is provided at the lower end of the upper clamping frame 1. Rotating columns 7 are fixedly connected to the front and rear ends of the upper clamping frame 1 and the lower clamping frame 6, respectively. A first pulley 8 is rotatably mounted on the outer wall of the rotating column 7. A first threaded groove 2 is provided at the upper end of the upper clamping frame 1. Second threaded grooves 9 are provided through the arc surfaces at both ends of the lower clamping frame 6. Fasteners are provided on both the second threaded groove 9 and the first threaded groove 2. A displacement component that is in contact with the ground is provided at the lower end of the lower clamping frame 6. The displacement component includes a connecting column 13, a sliding cylinder 14, a fixing plate 15, a spring 16, a protective ring 17, and a second pulley 20. The connecting column 13 is fixedly connected to the lower end of the lower clamping frame 6. A sliding cylinder 14 is slidably mounted on the outer wall of the connecting column 13. The lower end of the sliding cylinder 14 is fixedly connected to... The device includes a fixed plate 15 and a slide cylinder 14. The outer wall of the fixed plate 15 is fitted with a spring 16 for shock absorption. The other end of the spring 16 is fixed to the lower end of the lower clamping frame 6. The outer wall of the fixed plate 15 is fixed with a protective ring 17 for protection. The protective ring 17 is located outside the spring 16. The front and rear ends of the fixed plate 15 are rotatably equipped with second pulleys 20. During installation, the cable is clamped by fasteners. Then, by passing the traction line through the displacement member, the traction device is turned on to drag the cable on the device. During the cable laying process, when encountering bends and uneven areas, the two first pulleys 8 and two second pulleys 20 on the cable reduce the external friction experienced by the cable during sliding. Through the vibration damping structure formed by the fixed plate 15, the connecting column 13 / slide cylinder 14 and the spring 16, it can overcome low obstacles and improve the overall efficiency of pipeline laying.

[0022] Please see Figures 1-3In this embodiment, a cable 21 is placed at the center of the upper clamping frame 1 and the lower clamping frame 6, which are close to each other. The outer wall of the cable 21 is attached to one end of the three rubber clamps 4, which are close to each other. The first screw groove 2 is screwed and rotated on the first screw groove 2 or the second screw groove 9. By rotating the stud 3, the rubber clamps 4 on the stud 3 apply pressure to the outer wall of the cable 21, thereby fixing it by friction. The first baffle 10 and the lower clamping frame 6 form an integral structure with a first groove 11. The right end of the lower clamping frame 6 has a second groove 12. The first groove 11 and the second groove 12 are interconnected. The fixing plate 15 is arc-shaped and made of a high-toughness material, which makes it convenient for the second pulley 20 on the fixing plate 15 to elastically deform and adapt when it encounters uneven road surfaces during the displacement process, reducing the risk of friction and scratching the surface of the cable 21.

[0023] Please see Figures 3-5 In this embodiment, the fastener includes a stud 3, a rubber clamp 4, and a rotating ring 5. The stud 3 is threaded onto the first threaded groove 2 or the second threaded groove 9. The rubber clamp 4 is rotatably mounted on the lower end of the stud 3, and the rotating ring 5 is rotatably mounted on the stud 3. A connecting arc block 18 is fixedly connected to the upper end of the fixing plate 15, and the lower end of the lower clamping frame 6 is fixedly connected to the other end of the connecting arc block 18. The connecting arc block 18 can not only connect the lower clamping frame 6 and the fixing plate 15, but also improve the deformation efficiency of the fixing plate 15 through the elasticity of the connecting arc block 18. A first baffle 10 is fixedly connected to the left end of the lower clamping frame 6, and two second baffles 19 are fixedly connected to the right end of the first baffle 10. The two second baffles 19 are located on the periphery of the protective ring 17. The internal vibration damping components can be protected through the protective ring 17 and the second baffles 19.

[0024] During use, the device is fitted onto the outer wall of the cable 21. When it reaches a fixed position, the drive rotating ring 5 rotates the stud 3. The stud 3 is threadedly connected to the first screw groove 2 or the second screw groove 9, so that the rubber clamp 4 is tightly attached to the outer wall of the cable 21. The device is then fixed to the outer wall of the cable 21 by three fasteners. After the steel rope passes through the second groove 12 and the connecting post 13 in sequence, the other end is moved and laid by the traction device. During the laying of the cable 21, it slides in the pipe through the first pulley 8 and the two second pulleys 20 on the fixing plate 15. During the sliding, the vibration damping structure formed by the connecting post 13, the slide cylinder 14 and the spring 16 can effectively allow the lower end of the pipe to pass over low obstacles, thereby reducing friction and wear on the outer wall of the cable 21 and improving the overall laying efficiency of the cable. During the laying in the pipe, the components inside the protective ring 17 are protected by the first baffle 10 and the second baffle 19 to prevent the connecting post 13 and the slide cylinder 14 from being blocked and unable to perform normal up and down extension and retraction.
