Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable fixing bracket technology, and in particular to wear-resistant cable fixing brackets for power transmission lines. Background Technology
[0002] Transmission lines are lines that transmit electrical energy from power plants or substations to users. They are an important part of the power system and are mainly responsible for transmitting large-capacity, long-distance electrical energy. Transmission line cables are used to transmit and distribute electrical energy. During the cable laying process, fixed supports are usually used to support the cables to ensure that the cables are neatly and stably arranged during the laying process and to protect the cables from external mechanical damage and environmental influences.
[0003] Currently, in existing technologies, prefabricated brackets are commonly used to fix multi-layer cables. Prefabricated brackets, also known as modular cable brackets, are cable brackets that are installed directly on-site before or during cable laying. Their connection to the structure is generally through expansion bolts or embedded parts within the structure. When using prefabricated brackets to support cables, multiple cables are placed directly on the crossbeams of the prefabricated brackets, and the crossbeams are used to support and fix the cables.
[0004] However, during actual cable laying, when placing the cable on the crossbeam, in order to accurately place the cable in each support position, the construction personnel need to drag and adjust the position of the cable. During the dragging process, the cable is prone to friction with the crossbeam, which causes wear on the cable surface and reduces the service life of the cable. Utility Model Content
[0005] Therefore, it is necessary to provide wear-resistant cable fixing brackets for power transmission lines to address the problem that when the position of the cable is adjusted by dragging, the cable is prone to friction with the crossbeam, resulting in wear on the cable surface and thus reducing the cable's service life.
[0006] The device includes: a vertical rod; and multiple support mechanisms, each support mechanism including a horizontal rod installed with the vertical rod. The top of the horizontal rod has multiple evenly distributed placement slots. Multiple evenly distributed movable plates are slidably connected to the inner wall of the horizontal rod. The number and position of the movable plates correspond one-to-one with the number and position of the placement slots. The top of each movable plate extends into the corresponding placement slot and is rotatably connected to multiple evenly distributed first rollers. Multiple evenly distributed second rollers are rotatably connected to both sides of the inner wall of each placement slot. A sliding rod is fixedly connected to one side of each movable plate. The ends of the sliding rods away from the movable plates extend through the horizontal rod and are fixedly connected to a movable rod. A fixing component is provided at the top of the horizontal rod.
[0007] In one embodiment, the support mechanism further includes a threaded sleeve rotatably connected to one side of the crossbar. A threaded rod is threadedly connected to the inner wall of the threaded sleeve, and the top end of the threaded rod is fixedly connected to the bottom end of the moving rod. This facilitates driving multiple moving plates to simultaneously move multiple corresponding first rollers downwards.
[0008] In one embodiment, the fixing assembly includes a cylinder fixedly connected to one side of the inner wall of a crossbar. A circular rod is slidably connected to the inner wall of the cylinder. The top end of the circular rod extends through the cylinder and is fixedly connected to an installation rod. Multiple evenly distributed fixing plates are fixedly connected to the bottom end of the installation rod. The number and position of the fixing plates correspond one-to-one with the number and position of the multiple placement slots. A fixing rod is slidably connected to one side of the inner wall of the installation rod. A threaded groove is formed at the lower end of the surface of the fixing rod, and a first nut is threaded onto the surface of the threaded groove. After the cable is laid, the multiple fixing plates facilitate the simultaneous fixing of multiple cables located in multiple placement slots. Furthermore, the specific shape of the fixing plates and the action of the fixing rod and the first nut facilitate the fixing of cables of different diameters, thus improving the practicality of the device.
[0009] In one embodiment, the fixing plate has an overall ridge-like shape, and a first contact pad is fixedly connected to the inner surface of the fixing plate. This facilitates the adjustment of the cable's position during the fixing process by the inclined surface of the fixing plate, preventing the cable surface from contacting the surface of the second roller after fixing.
[0010] In one embodiment, a second contact pad is fixedly connected to the inner bottom wall of the placement groove, and the surface of the second contact pad has a through groove that matches the moving plate. This helps to increase the friction between the inner bottom wall of the placement groove and the cable surface.
[0011] In one embodiment, both the first and second contact pads are rubber components, and their surfaces are provided with multiple evenly distributed grooves. This helps to increase the friction between the first and second contact pads and the cable surface.
[0012] In one embodiment, the inner wall of the crossbar is provided with a groove that matches the moving plate and the slide bar. This facilitates limiting the movement path of the crossbar, i.e., the moving plate, and allows for the storage of the moving plate and the first roller during the cable fixing process.
[0013] Beneficial effects
[0014] 1. The above-mentioned support mechanism supports multiple cables through crossbars, and with the action of multiple placement slots, it is beneficial to initially limit the cables when placing them on the crossbars, avoiding mutual interference between adjacent cables. Furthermore, during the cable laying and dragging process, the first and second rollers rotate, which helps to reduce the friction between the cable and the crossbars during the dragging process, thereby protecting the cable surface. After the cable laying is completed, the first roller is driven into the crossbar by the drive moving plate, which helps to make the cable surface contact the inner bottom wall of the placement slot, thus ensuring the stability of the crossbar's support for the cable. With the action of the fixing components, multiple fixing plates simultaneously fix multiple cables located in multiple placement slots, thereby achieving the goal of protecting the cables during the cable laying process while ensuring the stability of the cable support and fixing after the cable laying.
[0015] 2. Setting the fixing plate in a ridge shape allows the fixing plate to be tilted to adjust the position of the cable during the fixing process, so that the cable in the fixing part enters the inner side of the fixing plate, avoiding the surface of the cable contacting the surface of the second roller after fixing, thereby enhancing the fixing effect of the cable.

[0029] The following is combined Figures 1-5 This invention describes a wear-resistant cable fixing bracket for power transmission lines.
[0030] In one embodiment, a wear-resistant cable fixing bracket for a power transmission line includes: a vertical rod 100; and multiple support mechanisms 200. Each support mechanism 200 includes a horizontal rod 210 installed with the vertical rod 100. The top of the horizontal rod 210 has multiple evenly distributed placement slots 211. The inner wall of the horizontal rod 210 is slidably connected to multiple evenly distributed movable plates 220. The number and position of the multiple movable plates 220 correspond one-to-one with the number and position of the multiple placement slots 211. The top of the movable plate 220 extends into the corresponding placement slot 211 and is rotatably connected to multiple evenly distributed first rollers 230. Both sides of the inner wall of the placement slot 211 are rotatably connected to multiple evenly distributed second rollers 260. A sliding rod 221 is fixedly connected to one side of the movable plate 220. The end of the multiple sliding rods 221 away from the movable plate 220 extends out of the horizontal rod 210 and is fixedly connected to a movable rod 222. A fixing component 250 is provided at the top of the horizontal rod 210.
[0031] In this embodiment, when using the device to support the cable, the vertical rod 100 is installed to the wall using expansion bolts. The horizontal cross-section of the vertical rod 100 is U-shaped. When installing the horizontal rod 210 to the vertical rod 100, one end of the horizontal rod 210 is inserted into the inside of the vertical rod 100, and the surface of the horizontal rod 210 is in contact with the inner wall of the vertical rod 100. The horizontal rod 210 and the vertical rod 100 are fixed with bolts and nuts. Both the horizontal rod 210 and the vertical rod 100 are stainless steel components.
[0032] The overall shape of the placement groove 211 is "U" shaped. The two sides of the bottom wall of the placement groove 211 are curved into arcs. When the device is in the initial state, the horizontal height of the highest point of the upper surface of the first roller 230 is higher than the horizontal height of the bottom wall of the placement groove 211. Therefore, when the cable is placed in the placement groove 211, the surface of the first roller 230 is in contact with the surface of the cable.
[0033] like Figure 4 As shown, the support mechanism 200 also includes a threaded sleeve 240 rotatably connected to one side of the crossbar 210. The inner wall of the threaded sleeve 240 is threadedly connected to a threaded rod 241, and the top end of the threaded rod 241 is fixedly connected to the bottom end of the movable rod 222.
[0034] In this embodiment, when the threaded rod 241 is fully moved into the threaded sleeve 240, the moving rod 222 moves downward to the lowest height. At this time, the moving rod 222 will drive the moving plate 220 to move downward to the lowest height through the sliding rod 221. At this time, the moving plate 220 will drive the first roller 230 to move downward to the lowest height simultaneously, so that the highest point of the upper surface of the first roller 230 is lower than the horizontal height of the bottom wall of the placement groove 211.
[0035] like Figure 2 , Figure 3 and Figure 5 As shown, the fixing component 250 includes a cylinder 251 fixedly connected to one side of the inner wall of the crossbar 210. A round rod 256 is slidably connected to the inner wall of the cylinder 251. The top end of the round rod 256 passes through the cylinder 251 and is fixedly connected to an installation rod 252. A plurality of evenly distributed fixing plates 253 are fixedly connected to the bottom end of the installation rod 252. The number and position of the fixing plates 253 correspond one-to-one with the number and position of the plurality of placement slots 211. A fixing rod 254 is slidably connected to one side of the inner wall of the installation rod 252. A threaded groove is opened at the lower end of the surface of the fixing rod 254. A first nut 255 is threadedly connected to the surface of the threaded groove.
[0036] In this embodiment, during the cable laying process, the round rod 256 is rotated, and the mounting rod 252 drives multiple fixing plates 253 to rotate synchronously, so that the multiple fixing plates 253 are moved away from the top of the placement groove 211.
[0037] A cylindrical hole matching the fixing rod 254 is provided on one side of the top of the crossbar 210. When the fixing rod 254 is inserted into the cylindrical hole, the threaded groove on the surface of the fixing rod 254 will pass through the cylindrical hole.
[0038] like Figure 5 As shown, the overall shape of the fixing plate 253 is ridge-shaped, and the inner surface of the fixing plate 253 is fixedly connected to the first contact pad 270.
[0039] In this embodiment, the center point of the fixing plate 253 and the center point of the placement groove 211 are on the same axis.
[0040] like Figure 4 As shown, a second contact pad 280 is fixedly connected to the inner bottom wall of the placement groove 211, and the surface of the second contact pad 280 is provided with a through groove that matches the moving plate 220.
[0041] In this embodiment, the moving plate 220 does not affect the second contact pad 280 when it moves up and down.
[0042] like Figure 4 and Figure 5As shown, both the first contact pad 270 and the second contact pad 280 are rubber components, and the surfaces of both the first contact pad 270 and the second contact pad 280 are provided with multiple evenly distributed grooves.
[0043] In this embodiment, the grooves on the surface of the first contact pad 270 and the grooves on the surface of the second contact pad 280 are both longitudinally distributed.
[0044] like Figure 3 As shown, the inner wall of the crossbar 210 is provided with a groove that matches the movable plate 220 and the slide bar 221.
[0045] In this embodiment, the surfaces of the movable plate 220 and the slide rod 221 are slidably connected to the inner wall of the slide groove, the slide groove is connected to the corresponding placement groove 211, and when the movable plate 220 and the slide rod 221 move downward to the lowest height in the slide groove, the first roller 230 will enter the slide groove.
[0046] Working principle: The vertical rod 100 is installed on the wall, and the horizontal rods 210 of the multiple support mechanisms 200 are sequentially installed on the vertical rod 100. After installation, when supporting the cables, multiple cables are placed into multiple placement slots 211. At this time, the surface of the cable is in contact with the surface of the first roller 230. When the cable is dragged by the worker during the laying process, the cable in the placement slot 211 will drive the first roller 230 to rotate synchronously. During the dragging process, when the part of the cable located in the placement slot 211 contacts the second roller 260, the second roller 260 will rotate synchronously. After the cable is laid, the worker rotates the threaded sleeve 240 on the horizontal rod 210 to drive the threaded rod 241 to move downward. Through the moving rod 222 and multiple sliding rods 221, multiple moving plates 220 and the corresponding first rollers 230 move downward and enter the sliding groove. This causes the lower end of the cable surface located in the placement groove 211 to contact the second contact pad 280 on the bottom wall of the placement groove 211. After this operation is completed, the operator rotates the moving rod 222 to rotate the mounting rod 252 and multiple fixing plates 253, so that the multiple fixing plates 253 are respectively located above the multiple placement grooves 211. At this time, the fixing rod 254 passes through the crossbar 210 and is threadedly connected to the threaded groove on the surface of the fixing rod 254 from below the crossbar 210 through the first nut 255. During the connection process, the fixing rod 254 will drive the mounting rod 252 to move downward, so that the mounting rod 252 will drive the multiple fixing plates 253 to move downward synchronously. During the downward movement, the multiple fixing plates 253 will respectively press and fix the cable surface located in the placement groove 211. When the fixing rod 254 can no longer move downward, the cable is fixed. The fixing operation of the cable at multiple support positions can be completed in sequence according to the above fixing steps.
[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0048] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
