Description

Technical Field

[0001] This utility model relates to the field of cable support technology, and in particular to an adjustable cable laying support. Background Technology

[0002] In the fields of power engineering and communications, cable supports, as key support structures of cable systems, are mainly used to bear the weight of cables, fix the cable route, and distribute mechanical stress, thereby ensuring the stable operation of cables in complex environments. Traditional cable supports are mostly made of rigid metal materials welded or bolted, which are simple to install, have high structural strength, are not easily deformed, can avoid line crossing interference, meet the long-term static laying requirements of cables, and facilitate later inspection and maintenance. In normal scenarios, they can effectively reduce the risk of cable sagging and improve the overall laying efficiency.

[0003] However, due to the fixed design of traditional brackets, the height and clamping position cannot be flexibly adjusted according to cable specifications or laying environment. When the cable is subjected to external forces (such as thermal expansion and contraction, equipment vibration), the rigid contact surface is prone to friction with the cable sheath. Long-term operation may lead to insulation wear or even short circuit hazards. Moreover, when it is necessary to adjust the route or replace the cable, it is often necessary to disassemble the entire bracket to meet the compatibility between the cable and the bracket. The operation is cumbersome and can easily damage the cable itself. In some scenarios (such as narrow tunnels and undulating terrain), fixed brackets are difficult to adapt to complex spatial layouts, which can easily lead to the cable being forced to bend or suspended, further aggravating the problem of local stress concentration and affecting the laying quality and safety. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an adjustable cable laying bracket, which solves the problems of rigidly fixed cable brackets that cannot be flexibly adjusted according to cable specifications or laying environment, which can easily damage cables and affect laying quality and safety.

[0005] According to an embodiment of the present invention, an adjustable cable laying bracket includes:

[0006] A fixed support is provided with a sliding groove on one side, and a side stop is provided on the fixed support that is detachably mounted vertically near and relative to the sliding groove.

[0007] A sliding rod, comprising a sliding seat and a rotating rod, wherein the sliding seat is slidably disposed within the sliding groove, and the rotating rod is detachably rotatably disposed on the side of the sliding seat opposite to the fixed support;

[0008] A fixing mechanism is fixedly disposed on one side of the sliding seat for fixing the sliding rod.

[0009] The technical principle of this utility model is as follows: several fixed supports are fixed in parallel, the height of the sliding rod in the sliding groove is adjusted according to the cable specifications or laying requirements, and after adjustment, the sliding rod is fixed by a fixing mechanism. Then the cable is placed on the sliding rod. When the cable is laid and moved, the rotating rod and the side stop rod will reduce the friction between the cable and the cable by rotating. After the cable is laid, the rotating rod will disperse the external force on the cable by rotating, thereby protecting the cable.

[0010] Furthermore, the fixing mechanism includes a threaded hole and a lead screw. The threaded hole is disposed on the side of the sliding seat perpendicular to the rotating rod. The lead screw is rotatably engaged in the threaded hole. The side wall of the fixing support is provided with a clearance groove for the lead screw to pass through and move up and down. A fixing plate is fixedly disposed on the lead screw near the clearance groove. The fixing plate can abut against the outer wall of the fixing support when the lead screw rotates inward and engages with the threaded hole.

[0011] Furthermore, a hexagonal bolt head is fixedly provided on the side of the fixing plate opposite to the threaded hole, and a knob is also coaxially fixedly provided on the top of the hexagonal bolt head.

[0012] Furthermore, a pair of mounting seats are fixedly installed at the upper and lower ends of the fixed support by bolts, and the side stop is rotatably connected to the two mounting seats respectively.

[0013] Furthermore, the sliding seat is fixedly provided with a clearance hole, which surrounds the side stop and is coaxially spaced with it.

[0014] Furthermore, the sliding seat is symmetrically fixed with mounting plates on both sides of the clearance hole, and a connecting plate is fixedly mounted on the mounting plate by bolts. A mounting ring is fixedly mounted on the side of the connecting plate away from the mounting plate, and the rotating rod is rotatably mounted in the mounting ring.

[0015] Furthermore, the rotating rod is configured with a tapered structure, thicker at the outer ends and thinner at the middle.

[0016] Furthermore, a limiting disk is coaxially fixed at the end of the rotating rod, and the diameter of the limiting disk is larger than the diameter of the end of the rotating rod.

[0017] Furthermore, the fixed support is provided with several connecting ears on both sides, and the connecting ears are provided with through holes for fixing.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. By adopting a height adjustment structure that combines a sliding groove and a sliding rod, the sliding rod can be flexibly raised and lowered according to the cable's outer diameter and laying requirements, precisely adjusting the height to ensure that the contact surface between the cable and the bracket is always in a reasonable position, resulting in more even cable stress. Since the rotating rod is detachably installed in the sliding seat, it can be quickly replaced or partially adjusted simply by releasing the lock between the rotating rod and the sliding seat, without disassembling the bracket body or cutting the cable. This simplifies the operation process, avoids damage to the cable body caused by disassembly and assembly, and significantly improves engineering maintenance efficiency.

[0020] 2. By adopting rotating side stops and rotating rods, the sliding friction can be converted into rolling friction by rotating the rods when the cable moves, which significantly reduces the risk of sheath wear, extends the service life of the cable, and avoids the risk of short circuit caused by insulation layer damage. The simultaneous support of multiple rotating rods can also disperse the concentrated stress caused by the cable's own weight and external loads, so that the cable is always in a natural and relaxed state, avoiding excessive local bending or suspended stress, and ensuring the continuous smoothness of the laying path.

[0025] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0026] like Figure 1-3As shown in the figure, this utility model embodiment proposes an adjustable cable laying bracket, including a fixed support 1. The fixed support 1 has a long box-shaped structure. Several connecting ears 14 are symmetrically fixed on both sides of the fixed support 1 near the back. The connecting ears 14 have a through hole in the middle, which allows bolts to pass through for connection and fixation with rigid structures such as walls. The fixed support 1 is preferably fixed vertically. A sliding groove 15 is provided on the front of the fixed support 1 along the long axis. A side stop bar 12 is vertically and detachably rotatably provided on the fixed support 1 near and relative to the sliding groove 15. A sliding rod 2 is slidably provided in the sliding groove 15. The sliding rod 2 includes a sliding seat 21 and a rotating rod 25. The sliding seat 21 fits the shape of the sliding groove 15 and the two slide against each other. The rotating rod 25 is detachably rotatably provided on the side of the sliding seat 21 away from the fixed support 1 to support the cable. A fixing mechanism 3 is fixedly provided on one side of the sliding seat 21 to fix the sliding rod 2.

[0027] The technical principle of this utility model is as follows: Several fixed supports 1 are fixed vertically in parallel. The height of the sliding rod 2 in the sliding groove 15 is adjusted according to the cable specifications or laying requirements. After adjustment, the sliding rod 2 is fixed by the fixing mechanism 3. Then the cable is placed on the sliding rod 2. When the cable is laid and moved, the rotating rod 25 and the side stop rod 12 will reduce the friction between them and the cable by rotating. After the cable is laid, the rotating rod 25 will disperse the external force on the cable by rotating, thereby protecting the cable.

[0028] This invention employs a height adjustment structure using a sliding groove 15 and a sliding rod 2. The sliding rod 2 can be flexibly raised and lowered according to the cable's outer diameter and laying requirements, precisely adjusting its height to ensure the cable and support contact surface are always in a reasonable position, resulting in more even cable stress. The rotating rod 25 is detachably mounted within the sliding seat 21, allowing for quick replacement or partial structural adjustments simply by releasing the lock between the rotating rod 25 and the sliding seat 21, without disassembling the support body or cutting the cable. This simplifies the operation process, avoids cable damage caused by disassembly and assembly, and significantly improves engineering maintenance efficiency. Furthermore, the use of a rotating side stop 12 and rotating rod 25 allows the side stop 12 and rotating rod 25 to convert sliding friction into rolling friction during cable movement, significantly reducing the risk of sheath wear, extending cable life, and avoiding short-circuit hazards caused by insulation damage. The simultaneous support of multiple rotating rods 25 also disperses the concentrated stress from the cable's own weight and external loads, keeping the cable in a naturally extended state, avoiding excessive local bending or suspended stress, and ensuring the continuous smoothness of the laying path.

[0029] like Figure 1-3As shown, in another embodiment, the fixing mechanism 3 can be configured as a pin positioning structure, specifically: multiple sets of equidistant positioning holes are preset on the side wall of the sliding groove 15, and elastic pins are set at corresponding positions on the sliding seat 21. When adjusting, pressing the pin releases the lock, and after sliding to the target height, the pin automatically engages with the positioning hole; it can also be configured as a clamping quick-release structure, specifically: an eccentric wheel or lever mechanism with a handle is set on the sliding seat 21, and the clamping block is driven to press against the inner wall of the sliding groove 15 by rotating or moving the handle; it can also be configured as an elastic buckle structure, with an elastic protrusion or groove set between the sliding seat 21 and the sliding groove 15, and the sliding rod 2 is fixed in stages by elastic deformation. In this embodiment, the fixing mechanism 3 is configured as a threaded hole 32 and a lead screw 31. The threaded hole 32 is set on the side of the sliding seat 21 perpendicular to the rotating rod 25, and the lead screw 31 is rotatably engaged in the threaded hole 32. The side wall of the support 1 is provided with a relief groove 13 for the lead screw 31 to pass through and move up and down. A fixing plate 33 is fixedly provided on the lead screw 31 near the relief groove 13. The fixing plate 33 is preferably circular or regular polygonal, and its diameter or lateral width is greater than the width of the relief groove 13, so that the fixing plate 33 can abut against the outer wall of the fixed support 1 when the lead screw 31 rotates and engages with the threaded hole 32, thereby firmly fixing the sliding seat 21. Furthermore, a hexagonal bolt head 34 is fixedly provided on the side of the fixing plate 33 away from the threaded hole 32. A knob 35 is also coaxially fixedly provided on the top of the hexagonal bolt head 34. Several anti-slip protrusions are evenly arranged around the arc surface of the knob 35 to facilitate the initial tightening of the lead screw 31 by using the knob 35, and then further tightening the lead screw 31 by locking the hexagonal bolt head 34 with a wrench or other tools to ensure the locking effect of the sliding seat 21.

[0030] like Figure 1-3 As shown, in another embodiment, a pair of mounting seats 11 are fixedly mounted at the upper and lower ends of the fixed support 1 by bolts. The side stop rods 12 are rotatably connected to the two mounting seats 11 respectively. The side stop rods 12 can prevent rigid friction between the cable and the fixed support. By rotating with the cable, the sliding friction is converted into rolling friction, which significantly reduces the risk of sheath wear. The mounting seats 11 can limit the upper and lower ends of the sliding groove 15 to prevent the sliding seat 21 from sliding out of the sliding groove 15. The sliding seat 21 and the side stop rods 12 can be quickly replaced by disassembling the mounting seats 11, which significantly improves the efficiency of engineering maintenance. Furthermore, the sliding seat 21 is fixedly provided with a clearance hole 211. The clearance hole 211 surrounds the side stop rod 12 and is coaxially spaced with it to further enhance the stability of the overall structure.

[0031] like Figure 1-3As shown in this embodiment, further, the sliding seat 21 is symmetrically fixed with mounting plates 22 on both sides of the clearance hole 211. The mounting plates 22 are parallel to the groove surface of the sliding groove 15. A connecting plate 23 is detachably fixed on the mounting plate 22 by bolts. A mounting ring 24 is fixed on the side of the connecting plate 23 away from the mounting plate 22. The rotating rod 25 is rotatably disposed in the mounting ring 24. The rotating rod 25 is perpendicular to the side stop rod 12. The rotation of the two can reduce the friction generated during cable laying, disperse the concentrated stress caused by the cable's own weight and external load, and keep the cable in a naturally stretched state, thus protecting the cable together.

[0032] like Figure 1-3 As shown, in another embodiment, the rotating rod 25 is configured with a tapered structure from both ends to the middle, being thicker on the outside and thinner on the inside. Since the diameter of the middle part of the rotating rod 25 is smaller than that of the two ends, the cable will be concentrated in the middle of the rotating rod 25 when placed on it, thereby avoiding falling off the rotating rod 25 or rubbing against the edge, improving the laying quality, and ensuring the continuity and smoothness of the laying path. Furthermore, a limiting plate 26 is coaxially fixed at the end of the rotating rod 25. The diameter of the limiting plate 26 is larger than the diameter of the end of the rotating rod 25. The limiting plate 26 will block the cable, further preventing the cable from falling off the rotating rod 25. The rod surfaces of the rotating rod 25 and the side stop bar 12 can also be coated with anti-slip and wear-resistant material to further increase the laying effect and service life of the bracket.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
