Description

Technical Field

[0001] This utility model relates to the field of cable technology, specifically a cable with a wear-resistant outer surface. Background Technology

[0002] A cable is an electrical energy or signal transmission device, usually composed of several or several groups of conductors, each group of conductors is insulated from each other, and they are often twisted around a central core. The entire cable is covered with a highly insulating outer layer. Cable laying refers to the process of laying and installing cables along a surveyed route to form a cable line. Depending on the application, it can be divided into several laying methods such as overhead, underground (pipes and direct burial), underwater, wall, and tunnel.

[0003] When cables are erected in the air, they are often fixed to utility poles using fasteners. During installation, the cable needs to be tightened to the fastener before it is secured to the pole. This method of fixing the cable by pressing it tightly at a certain point can cause the cable to sway between poles due to wind. This swaying can cause significant wear at the connection point between the cable and the fastener. While most cables are wrapped with several protective layers to protect them, prolonged wear in one spot can damage the cable and make it difficult to repair.

[0004] Based on this, a cable with a wear-resistant outer surface is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

Clamping blocks are symmetrically attached to the outer side of the wear-resistant layer. Each clamping block has several first fixing plates fixedly mounted on it. Two clamping blocks are fixedly connected by first bolts. The two clamping blocks are located between two sliding blocks, which are slidably disposed inside an upper fixing tube and a lower fixing tube, respectively. Several second fixing plates are fixedly mounted on both sides of the upper and lower fixing tubes, which are fixedly connected by second bolts. Several third fixing plates are fixedly mounted at the bottom of the lower fixing tube.

[0014] In one alternative: a plurality of circular perforations are provided on one side of the clamping block, and the circular perforations pass through the stop plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] In one embodiment, such as Figures 1-6 As shown, a wear-resistant cable includes a cable body 11 and clamping blocks 13. A wear-resistant layer 12 is fixedly provided on the outer side of the cable body 11. Clamping blocks 13 are symmetrically attached to the outer side of the wear-resistant layer 12. Several first fixing plates 15 are fixedly provided on each clamping block 13. Two clamping blocks 13 are fixedly connected by first bolts. The two clamping blocks 13 are located between two sliding blocks 17. The two sliding blocks 17 are slidably disposed inside an upper fixing tube 19 and a lower fixing tube 20, respectively. Several second fixing plates are fixedly provided on both sides of the upper fixing tube 19 and the lower fixing tube 20. The upper and lower fixed tubes 19 and 20 are fixedly connected by a second bolt. Several third fixed plates are fixedly provided at the bottom of the lower fixed tube 20. Both the upper and lower fixed tubes 19 and 20 are provided with compensation mechanisms for compensating the displacement distance of the clamping block 13. Both sides of the upper and lower fixed tubes 19 and 20 are provided with arc-shaped through holes. The arc-shaped through holes are provided with sliding mechanisms for reducing the wear of the wear-resistant layer 12. The compensation mechanism facilitates the compensation of the displacement generated by the clamping block 13, thereby reducing the wear between the cable and the clamping block 13. The sliding mechanism reduces the wear between the wear-resistant layer 12 and the ends of the upper and lower fixed tubes 19 and 20.

[0026] Each of the sliding blocks 17 has a symmetrical limiting groove at one end, and a limiting rod 18 is slidably provided in each limiting groove. The limiting rod 18 is fixedly installed inside the upper fixed tube 19 and the lower fixed tube 20. In use, it is convenient to limit the sliding block 17 inside the upper fixed tube 19 and the lower fixed tube 20, so that the sliding block 17 can slide.

[0027] The compensation mechanism includes a return spring 22. The sliding block 17 has symmetrically fitted return springs 22 at both ends. Each return spring 22 has a fixed plate at both ends. One fixed plate of each return spring 22 is fixed inside one side of the upper fixed tube 19 and the lower fixed tube 20. A damper 21 is provided in the middle of each return spring 22, fixed between the two fixed plates. A support plate is fixed between the fixed plates on the same side of each return spring 22. A limiting groove 16 is symmetrically provided on one side of each sliding block 17, aligned with the first fixed plate 15. In use, when the cable needs to be installed, the cable body 11 is clamped and fixed by two clamping blocks 13. The two clamping blocks 13 are fixed by the first bolt, which then causes the sliding block 17 inside the upper fixed tube 19 and the lower fixed tube 20 to... The sliding block 17 is tightly attached to both sides of the two clamping blocks 13, and the first fixing plate 15 is located inside the limiting groove 16. The upper fixing tube 19 and the lower fixing tube 20 are fixed by the second bolt, and the lower fixing tube 20 is installed on the utility pole. Since both sides of the sliding block 17 are tightly attached to one end of several return springs 22, the clamping block 13 is located in the middle of the upper fixing tube 19 and the lower fixing tube 20. When the cable shakes significantly during use, the clamping block 13 will cause the sliding block 17 to slide inside the upper fixing tube 19 and the lower fixing tube 20. At the same time, the damper 21 and the return spring 22 cooperate to buffer and reset, thereby compensating for the displacement of the cable shaking and reducing the wear between the cable and the clamping block 13. The upper fixing tube 19 and the lower fixing tube 20 are equipped with a linkage assembly that enables several dampers 21 and return springs 22 to work simultaneously.

[0028] The linkage assembly includes a connecting rod 23. A first hinge seat is fixedly provided on a fixed plate at one end of the return spring 22. The connecting rod 23 is hinged on the first hinge seat. A second hinge seat is hinged on the other end of the connecting rod 23. The second hinge seats on the same side are fixedly provided on one side of the same sliding plate 24. Several guide slide rods are slidably provided on the sliding plate 24. The guide slide rods are fixedly provided inside the upper fixed tube 19 and the lower fixed tube 20. In use, when the sliding block 17 slides to one side, it compresses the return spring 22 on one side. This causes the fixed plate to pull the sliding plate 24 to slide through the connecting rod 23. The sliding plate 24 drives the uncompressed return spring 22 to compress through another connecting rod 23, so that the several dampers 21 and the return spring 22 perform buffering and reset work.

[0029] The sliding mechanism includes a fixing ring 25. The fixing ring 25 is fixedly installed in the arc-shaped through holes at both ends of the upper fixing tube 19 and the lower fixing tube 20. The fixing ring 25 is semi-circular. The fixing ring 25 has a plurality of mounting grooves arranged in a circular array inside. The mounting grooves are fitted with balls 26. When in use, the wear-resistant layer 12 is in close contact with the balls 26. When the cable body 11 swings during use, the balls 26 can slide, thereby reducing the wear of the wear-resistant layer 12.

[0030] Each clamping block 13 is fixedly provided with a stop plate 14 on its inner side. One side of the stop plate 14 is a protective layer, which facilitates the increase of the fixing effect between the clamping block 13 and the wear-resistant layer 12 during use.

[0031] The clamping block 13 has several circular perforations on one side, which pass through the stop plate 14 to facilitate heat dissipation at the connection between the stop plate 14 and the wear-resistant layer 12 and prevent the temperature at the connection from getting too high.

[0032] The above embodiment discloses a cable with a wear-resistant outer surface. During installation, the cable body 11 is clamped and fixed by two clamping blocks 13. The two clamping blocks 13 are fixed by a first bolt. Then, the sliding blocks 17 inside the upper fixing tube 19 and lower fixing tube 20 are tightly attached to both sides of the two clamping blocks 13, and the first fixing plate 15 is located inside the limiting groove 16. The upper fixing tube 19 and lower fixing tube 20 are fixed by a second bolt, and the lower fixing tube 20 is installed on a utility pole. Since both sides of the sliding blocks 17 are tightly attached to one end of several return springs 22, the clamping blocks 13 are located in the middle of the upper fixing tube 19 and lower fixing tube 20. When the cable is in use... When significant shaking occurs during use, the clamping block 13 causes the sliding block 17 to slide inside the upper fixed tube 19 and the lower fixed tube 20. This causes the sliding block 17 to compress the return spring 22 on one side, which in turn causes the fixed plate to pull the sliding plate 24 to slide via the connecting rod 23. The sliding plate 24, via another connecting rod 23, compresses the uncompressed return spring 22, causing several dampers 21 and return springs 22 to perform buffering and reset work. This compensates for the displacement caused by the shaking of the cable and reduces the wear between the cable and the clamping block 13. At the same time, the remaining part of the wear-resistant layer 12 is rotated by the ball bearings 26, which reduces the wear of the wear-resistant layer 12.

[0033] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
