Description

Technical Field

[0001] The present application relates to the field of cable maintenance technology, and in particular to a cable maintenance and deicing device. Background Art

[0002] During cable maintenance, especially in cold weather, ice often forms on the cable surface, which not only affects the normal operation of the cable, but may also cause irreversible damage to the equipment.

[0003] Traditional de-icing devices mainly use sharp blades to peel off ice from the cable surface by rotating. Although they can effectively remove ice, the sharp characteristics of the blades often scratch the insulation layer and outer skin of the cable, causing the cable performance to deteriorate or increase the risk of failure. This damage may cause more serious safety hazards and significantly increase the subsequent maintenance costs. For this reason, we urgently need to provide a cable maintenance and de-icing device.

[0019] The following is a further detailed description of the present application in conjunction with the attached Figures 1-4 drawings.

[0020] An embodiment of the present application discloses a cable maintenance and ice removal device. Refer to Figures 1-4, including a machine body 1. A fixed pulley 2 is rotatably connected to the bottom of the inner wall of the machine body 1. Motor boxes 7 are fixedly installed at both the upper and lower ends of the side of the machine body 1. Connecting seats 8 are fixedly installed inside the motor boxes 7. Servo motors 9 are installed inside the motor boxes 7. The output end of the servo motor 9 penetrates through the motor box 7 and is connected to an eccentric wheel 10. A fitting block 11 is provided at the upper end of the eccentric wheel 10. A movable rod 12 is fixedly installed in the middle of the upper end of the fitting block 11. The upper end of the movable rod 12 penetrates through the connecting seat 8 and is fixedly installed with a breaker hammer 13. When the servo motor 9 is started, its output end drives the eccentric wheel 10 to rotate. Due to the structural characteristics of the eccentric wheel 10, during its rotation, the distances from different positions on the circumference of the eccentric wheel 10 to the rotation center are constantly changing. When the part with the longer radius of the eccentric wheel 10 rotates to contact the fitting block 11, it will push the fitting block 11 upward, thereby driving the movable rod 12 and the breaker hammer 13 to move upward. When the eccentric wheel 10 continues to rotate and the part with the shorter radius contacts the fitting block 11, the breaker hammer 13 moves downward under the action of its own gravity and the return spring 14. With the continuous rotation of the eccentric wheel 10, the breaker hammer 13 will perform an up-and-down reciprocating motion, thereby knocking and breaking the ice layer on the surface of the cable. The two breaker hammers 13 are symmetrically arranged on the side of the machine body 1. Through the two breaker hammers 13 arranged symmetrically up and down, under the action of the servo motor 9 driving the eccentric wheel 10, an opposite reciprocating motion is achieved, and the ice layer can be knocked and broken from both sides of the cable at the same time, making the ice cubes easier to fall off from the surface of the cable, improving the ice removal efficiency and ice removal effect. Return springs 14 are fixedly installed on both sides of the upper end of the fitting block 11. The other ends of the return springs 14 are fixedly installed on the surface of the connecting seat 8. The setting of the return springs 14 ensures that the breaker hammer 13 can be reset in time after knocking, ensuring the stable operation of the device.

[0021] Refer to Figures 1-4, a regulating screw rod 3 is threadedly connected to the upper end of the body 1. A hand wheel 4 is fixedly installed at the upper end of the regulating screw rod 3. The bottom of the regulating screw rod 3 is rotatably connected to a pulley seat 5. An active pulley 6 is rotatably connected inside the pulley seat 5. By rotating the hand wheel 4, the regulating screw rod 3 is driven to rotate. Since the regulating screw rod 3 is threadedly connected to the body 1, when the regulating screw rod 3 rotates, it will move axially up and down on the body 1. And the bottom of the regulating screw rod 3 is rotatably connected to the pulley seat 5. Therefore, the up and down movement of the regulating screw rod 3 will drive the pulley seat 5 and the active pulley 6 installed inside the pulley seat 5 to move up and down together. And the sliders 16 at both ends of the pulley seat 5 slide in the chutes 15 on both sides of the body 1, playing a guiding and stabilizing role to ensure that the pulley seat 5 can move up and down smoothly, thereby realizing the precise adjustment of the position of the active pulley 6, which can meet the ice removal requirements for cables of different diameters, increasing the versatility and application range of the device. Sliders 16 are fixedly installed at both ends of the pulley seat 5. A rotary motor 17 is installed outside one of the sliders 16. The output end of the rotary motor 17 penetrates through the slider 16 and the pulley seat 5 and is connected to the side of the active pulley 6. Chutes 15 adapted to the sliders 16 are provided in the middle of both sides of the body 1. The surface of the slider 16 is slidably connected inside the chute 15. The cooperation between the slider 16 and the chute 15 makes the pulley seat 5 move more smoothly when moving up and down, further improving the reliability of the device.

[0022] The implementation principle of a cable maintenance and ice removal device in an embodiment of the present application is as follows: When specifically used, first pass the cable through the inside of the body 1 so that the position of the cable is in the middle of the fixed pulley 2 and the active pulley 6. Then rotate the regulating screw rod 3 to drive the connecting seat 8 to move downward, adjust the position of the active pulley 6 to clamp the cable between the active pulley 6 and the fixed pulley 2. Then start the rotary motor 17 to drive the active pulley 6 to rotate, so that the entire body 1 moves on the surface of the cable. At the same time, start two servo motors 9 to drive the eccentric wheels 10 to rotate respectively. Every time the two eccentric wheels 10 rotate one week, the engaging blocks 11 on their outer sides will be ejected, so that the two movable rods 12 and the breaking hammers 13 perform reciprocating activities in opposite directions. Through the movement of the two breaking hammers 13, the ice cubes are knocked off and removed from the surface of the cable.
