Description

Technical Field

[0001] The utility model belongs to the field of cable protection, in particular to a cable anti-wear device. Background Art

[0002] Cables are wires made of one or more mutually insulated conductors and an outer insulating protective layer. When cables are used, they are connected to motors or other equipment around the motors. The vibrations generated when the motors are working will drive the cables to vibrate, causing friction between the cables and the ground, causing cable wear. At the same time, when multiple cables are interwoven, friction will also occur between the cables, causing wear problems between the cables. Later, the power needs to be turned off to wrap protective tape around the worn parts or replace the insulation layer, wasting working time and increasing costs. Utility Model Content

[0016] In order to better understand the purpose, structure and function of the utility model, the cable anti-wear device of the utility model is further described in detail below with reference to the accompanying drawings.

[0017] like Figures 1 to 5 As shown, a cable wear prevention device of the utility model includes a connecting ring 1, and support frames are distributed at intervals on the connecting ring 1. A plurality of support frames can be arranged on the connecting ring 1, and each support frame can provide limited support for the cable to prevent the contact wear between the cables caused by the vibration of the motor. At the same time, a bracket is also provided on the outer wall of the connecting ring 1, and the bracket can support the connecting ring 1 so that each support frame on the support ring is at a distance from the ground, that is, a distance is created between the cable arranged on the support frame and the ground to prevent the cable from rubbing against the ground. Among them, the support frame for supporting the cable includes limit members distributed on the connecting ring 1, and a telescopic rod is provided on each limit member, and a clamping component for limiting the cable is provided on each telescopic rod. The clamping assembly specifically includes a placement plate 10 disposed on the telescopic rod, and a second slide groove 11 is opened on the placement plate 10, so that the placement plate 10 is formed into a U shape, and baffles 13 are provided at both ends of the placement plate 10 through screws, and a screw rod 14 is rotatably provided between the two baffles 13, and the threads on the screw rod 14 are two oppositely arranged positive and negative threads, and the screw rod 14 passes through the second slide groove 11. Figure 1 and Figure 4 As shown, an arc frame 12 is symmetrically arranged at the center of the second slide groove 11 , and the positive and negative threads on the screw rod 14 are threadedly connected with the two arc frames 12 , and a knob 15 is arranged at one end of the screw rod 14 .

[0018] When the cable needs to be clamped in the clamping assembly, the screw rod 14 can be rotated by the knob 15, and the two arc frames 12 threadedly connected on the bolt will move away from each other, thereby expanding the distance between the two arc frames 12. At this time, the cable is placed between the two expanded arc frames 12, and then the knob 15 is rotated in the opposite direction. The knob 15 drives the two arc frames 12 to move closer to each other through the screw rod 14, so that the cable is clamped between the two arc frames 12. In order to prevent the inner wall of the arc frame 12 from causing wear and damage to the cable, a rubber pad 16 is provided on the inner wall of the arc frame 12.

[0019] like Figure 1 and Figure 2 As shown, the limiting member includes a mounting block 4, and a groove 2 is provided in the mounting block 4 for inserting the limiting ring. The thickness of the groove 2 is the same as the wall thickness of the connecting ring 1, and the groove 2 is arc-shaped, and its curvature is the same as the curvature of the connecting ring 1. When the mounting block 4 is installed on the connecting ring 1, it can be directly inserted into the connecting ring 1 through the groove 2 on the mounting block 4 toward the side wall of the connecting ring 1 to complete the connection between the mounting block 4 and the connecting ring 1. The operation is simple and the disassembly and assembly are convenient, saving time and effort. It is understandable that a plurality of support frames can be installed on the connecting ring 1 through the limiting member, and the number of support frames installed on the connecting ring 1 and their installation positions can be selected according to the actual number and position of cables, and no excessive restrictions are made here.

[0020] In order to increase the stability of the limiter on the connecting ring 1, a fixing block 5 is provided on the mounting block 4 of the limiter, and a through slot 51 is provided on the fixing block 5, that is, the fixing block 5 is an inverted U-shaped setting with the opening facing downward. A slide plate 6 and a resistance block 7 are slidably provided in the through slot 51, and the slide plate 6 and the resistance block 7 slide up and down in the through slot 51, and the resistance block 7 is located below the slide plate 6, and the two ends of the slide plate 6 extend outward relative to the fixing block 5. At the same time, the resistance block 7 passes through the mounting block 4, and a spring 8 is provided in the through slot 51, one end of the spring 8 is connected to the through slot 51, and the other end is connected to the slide plate 6. When installing the connecting ring 1 through the groove 2 on the mounting block 4, the sliding plate 6 and the resistance block 7 need to be lifted upward through the extension end of the sliding plate 6, and when lifted, the sliding plate 6 will compress the spring 8, and then the sliding plate 6 can be inserted into the connecting ring 1 through the groove 2 on the mounting block 4, and the sliding plate 6 is released, and the spring 8 pushes the sliding plate 6 downward, and the sliding plate 6 pushes the resistance block 7 downward, so that the resistance block 7 fits the outer wall of the connecting ring 1, thereby increasing the friction between the resistance block 7 and the connecting ring 1, and improving the stability of the limiter and the connecting ring 1. Among them, the bottom surface of the resistance block 7 is an arc that matches the outer wall of the connecting ring 1, and the resistance block 7 is preferably rubber, which can increase the friction between the resistance block 7 and the connecting ring 1. When the mounting block 4 needs to be disassembled, the sliding plate 6 is lifted, and the sliding plate 6 drives the resistance block 7 to rise, and the sliding plate 6 compresses the spring 8 again, and then the mounting block 4 can be removed from the connecting ring 1. After removal, the sliding plate 6 is released, and the sliding plate 6 pushes the resistance block 7 to return to the initial position through the spring 8.

[0021] It should be noted that the arrangement of the telescopic rod can facilitate the adjustment of the spacing between adjacent cables, and the telescopic rod specifically includes a branch pipe 3 arranged on the mounting block 4, an inner rod 9 is telescopically arranged in the branch pipe 3, and a placement plate 10 is arranged on the inner rod 9. The branch pipe 3 and the inner rod 9 in the telescopic rod can be threaded or in other ways to meet the use requirements. In this embodiment, the telescopic rod is preferably provided with a convex strip 31 on the inner wall of the branch pipe 3, and a first slide groove 91 corresponding to the convex strip 31 is opened on the side wall of the inner rod 9, and the convex strip 31 arranged on the inner wall of the branch pipe 3 and the first slide groove 91 opened on the side wall of the inner rod 9 are both arranged along the axis of the corresponding branch pipe 3 and the inner rod 9, and a thread is arranged on the inner rod 9, and a first nut 17 is rotatably arranged at the top of the branch pipe 3, and the first nut 17 is threadedly matched with the inner rod 9. In this way, the cables that are close to each other can be connected separately through the clamping assembly, and then the corresponding first nut 17 on each branch pipe 3 can be rotated. The rotation of the first nut 17 can complete the adjustment of the inner rod 9 on the branch pipe 3, and the adjustment distance between each branch pipe 3 and the corresponding inner rod 9 can be freely adjusted to meet the use requirements.

[0022] like Figure 5 As shown, the bracket includes a support tube 18 arranged on the outer wall of the connecting ring 1, a second nut 21 is rotatably provided at the bottom end of the support tube 18, and a threaded rod 20 is slidably provided in the support tube 18, and a grounding plate 19 is provided at the bottom end of the threaded rod 20. The support tube 18 and the grounding plate 19 are fixed, and then the second nut 21 is rotated, so that the threaded rod 20 can be slid out of the support tube 18. In this way, the height of the connecting ring 1 relative to the grounding plate 19 is increased, and when the distance between the connecting ring 1 and the grounding plate 19 needs to be shortened, the second nut 21 can be rotated in the opposite direction, and the second nut 21 drives the threaded rod 20 threadedly connected thereto to slide into the support tube 18. In this way, when the clamping components on each supporting frame drive the clamped cables to be adjusted outward through the telescopic rod, the cables connected to the supporting frame at the bottom of the connecting ring 1 can be prevented from contacting the ground by adjusting the bracket.

[0023] Instructions for use: select an appropriate number of support frames according to the number of cables, then lift the slide plate 6 set on the fixed block 5 on the support frame, after the slide plate 6 lifts the resistance block 7, insert the mounting block 4 into the connecting ring 1, then turn the knob 15 according to the cable diameter, the knob 15 drives the screw 14 to rotate, the screw 14 adjusts the distance between the two arc frames 12, put the cable in the two arc frames, and then turn the knob 15 in the opposite direction, the knob 15 drives the screw 14 to adjust the two arc frames 12 to be relatively close and clamp the cable, then adjust the first nut 17 on the telescopic rod, adjust the cable to an appropriate distance from the connecting ring 1, and then adjust the distance of the connecting ring 1 relative to the floor 19 through the second nut 21.
