Description

Technical Field

[0001] This utility model relates to the field of power transmission and transformation equipment technology, specifically an adjustable high-voltage cable support device. Background Technology

[0002] In the construction and operation of high-voltage power systems, the standardized laying of cables is crucial to ensuring the safe and stable operation of the power grid. During the laying of high-voltage cables, the bending radius, height above ground, horizontal spacing, and directional angle must be strictly controlled to avoid faults caused by mechanical stress, electric field concentration, or insulation damage. Therefore, cable support devices are commonly used in engineering projects to support and position the cables. Traditional support structures are mostly fixed angle steel brackets, welded arms, or pre-embedded supports, whose height and angle cannot be adjusted after installation.

[0003] However, existing adjustable cable support devices still have significant shortcomings: traditional cable supports are still fixed structures and do not have angle adjustment functions at all. Once there is a height difference or a turn in the path, they can only be forcibly adapted by cutting, welding or adding pads on site, which results in low construction efficiency and poor reliability. In addition, most support devices can only clamp a single cable, which is difficult to meet the needs of multi-circuit parallel laying, and the clamping parts are often in direct metal contact, which can easily scratch the cable outer sheath.

[0029] Example 1:

[0030] like Figures 1 to 3 As shown, this embodiment provides an adjustable high-voltage cable support device, comprising: a support plate 1; a height adjustment component 2, disposed on one side of the support plate 1, including a sliding groove 21 formed on one side of the support plate 1, and a sliding block 23 embedded and sliding within the sliding groove 21; an angle adjustment component 3, comprising two sets, located on one side of the sliding block 23, including a support rod 31 fixedly connected to one side of the sliding block 23, and a rotating plate 32, one end of which is hinged to one side inside the support rod 31; and a support module 4, disposed outside the rotating plate 32, including a first clamping component 41 disposed on the top of one side of the rotating plate 32, and a second clamping component 42 disposed on one side of the rotating plate 32.

[0031] In this embodiment, the angle adjustment component 3 and the support module 4 constitute an adjustable high-voltage cable support device according to this application.

[0032] In this embodiment, the support plate 1 is made of high-strength steel with anti-corrosion treatment, and is used to fix it in the support position and install the height adjustment component 2. The height adjustment component 2 includes a sliding groove 21 and two sets of sliding blocks 23, used to adjust the height of the support module 4. The sliding groove 21 is formed on one side of the support plate 1 and extends vertically, used for the sliding blocks 23 to be inserted and slid. The sliding blocks 23 are made of high-strength aluminum alloy and are used to connect the support rod 31 and drive it to rise and fall. The angle adjustment component 3 is used to adjust the angle of the support module 4. The rotating plate 32 is made of high-strength aluminum alloy and is used to install the support module 4 and rotate with the angle adjustment. The support module 4 includes a first clamping component 41 and a second clamping component 42, used to clamp and fix the high-voltage cable. The support plate 1 is fixed to the target position through the threaded fixing hole; the sliding block 23 slides along the sliding groove 21, driving the support rod 31 and the support module 4 to adjust the height and lock; the rotating plate 32 rotates around the hinge point of the support rod 31 to adjust the angle of the support module 4 and lock; the first clamping assembly 41 and the second clamping assembly 42 clamp the two sets of high-voltage cables respectively to complete the support fixation. This achieves bidirectional adjustment of the support height and angle, adapting to high-voltage cables with different arrangements. The two clamping assemblies can simultaneously fix multiple sets of cables, improving the support flexibility and practicality.

[0033] Specifically, the height adjustment component 2 includes: a locking hole 22, which is vertically opened on the support plate 1; a locking bolt 24, which is threadedly connected to the support rod 31 located on the top side of the sliding block 23 and inside the locking hole 22 of the support plate 1.

[0034] In this embodiment, pushing the support rod 31 causes the sliding block 23 to slide vertically along the sliding groove 21. After adjusting to the target height, the locking bolt 24 is screwed into the threaded hole of the support rod 31 until one end passes through and is embedded in the corresponding locking hole 22. The sliding block 23 is locked by thread engagement, thereby fixing the height of the support rod 31. This achieves precise adjustment and stable locking of the support height. The spacing design of the locking holes 22 meets different height requirements and prevents loosening after height adjustment.

[0035] Example 2:

[0036] Based on Embodiment 1, in order to provide a suitable cable support angle adjustment function, an angle adjustment component 3 is provided on one side of the sliding block 23.

[0037] Specifically, the angle adjustment component 3 includes: a rotating block 33, which is fixedly disposed at the bottom of one side of the rotating plate 32 and rotates inside the support rod 31; a rotating groove 34, which is opened inside the support rod 31 and the rotating block 33 slides inside the rotating groove 34; a limiting hole 35, which is opened on the support rod 31 and three sets of them are provided; a limiting bolt 36, which is threadedly connected to the limiting hole 35 and the rotating block 33; and a limiting nut 37, which is threadedly rotated at one end of the limiting bolt 36.

[0038] In a preferred embodiment, the rotating plate 32 is turned to move the rotating block 33 along the rotating groove 34 to adjust it to the target angle, aligning the threaded hole of the rotating block 33 with the corresponding limiting hole 35. The limiting bolt 36 is then passed through the limiting hole 35 and screwed into the threaded hole of the rotating block 33, and the limiting nut 37 is tightened onto one end of the limiting bolt 36 to complete the angle locking. This achieves multi-angle adjustment, with three sets of limiting holes 35 ensuring precise angle adjustment, and the limiting nut 37 enhancing locking stability and preventing angle deviation caused by vibration.

[0039] Example 3:

[0040] Based on Embodiment 2, in order to provide cable clamping and anti-slip, a first clamping assembly 41 and a second clamping assembly 42 are respectively provided on one side and the top of one side of the rotating plate 32.

[0041] Specifically, the first clamping assembly 41 includes: a first lower clamping block 411, disposed on one side of the top of the rotating plate 32; threaded rods 412, disposed on both sides of the top of the rotating plate 32 and passing through both sides of the first lower clamping block 411; a first upper clamping block 413, which moves up and down on the top of the first lower clamping block 411 and is passed through by two sets of threaded rods 412 on both sides; a clamping nut 414, threadedly connected to the threaded rods 412 and located on both sides of the first upper clamping block 413; and a first rubber clamping block 415, disposed inside the first lower clamping block 411 and the first upper clamping block 413.

[0042] In this embodiment, the first rubber clamp 415 is made of insulating and wear-resistant rubber to increase friction and provide insulation protection for the cable. The cable is placed on the first rubber clamp 415 inside the first lower clamping block 411; the first upper clamping block 413 is moved downwards so that its inner first rubber clamp 415 fits against the top of the cable; the clamping nuts 414 on both sides of the first upper clamping block 413 are tightened, and through the threaded engagement of the nuts with the threaded rod 412, the first upper clamping block 413 is pushed downwards to press firmly, completing the cable clamping. The rubber clamps provide insulation protection and stable clamping of the cable, preventing direct metal contact and damage to the cable sheath. The clamping nuts 414 ensure adjustable clamping force to accommodate cables of different diameters.

[0043] Specifically, the second clamping assembly 42 includes: a sliding groove 421, formed on both sides of one end of the rotating plate 32; a second lower clamping block 422, which moves up and down on one end of the rotating plate 32; a second upper clamping block 423, which moves up and down on one end of the rotating plate 32 and is located on top of the second lower clamping block 422; a slider 424, which is disposed near one end of the second lower clamping block 422 and the second upper clamping block 423, and is embedded in the sliding groove 421 and slides; two sets of clamping bolts 425, which are threadedly connected to both sides of the second lower clamping block 422 and the second upper clamping block 423; and a second rubber clamping block 426, which is disposed inside the second lower clamping block 422 and the second upper clamping block 423.

[0044] In this configuration, the slide groove 421 is a T-shaped groove for the slider 424 to slide into. The slider 424 is made of high-strength aluminum alloy and is a T-shaped block to prevent the clamping block from shifting. The second rubber clamping block 426 is made of insulating and wear-resistant rubber to protect the cable and increase friction. Adjust the height of the second lower clamping block 422 along the slide groove 421 and place the cable on the inner side of the second rubber clamping block 426; move the second upper clamping block 423 downward along the slide groove 421 so that its inner side of the second rubber clamping block 426 fits against the top of the cable; tighten the clamping bolts 425 on both sides to bring the second upper clamping block 423 closer to the second lower clamping block 422, completing the cable clamping. The slider and the slide groove cooperate to achieve fine adjustment of the clamping block height to adapt to cables in different positions, the rubber clamping blocks ensure insulation and anti-slip, and the two sets of clamping bolts ensure stable clamping.

[0045] In actual use, firstly, the user fixes the support plate 1 to the position where the cable needs to be supported through the threaded fixing hole. Then, the sliding block 23 is inserted into the sliding groove 21 and slid to adjust the height of the support rod 31. When the required height is reached, the user tightens the locking bolt 24 to one side of the support rod 31 and the corresponding locking hole 22 to lock the height of the support rod 31. Then, the user pulls the rotating plate 32 upward, and the rotating plate 32 slides at the bottom inside the support rod 31. The rotating block 33 slides inside the rotating groove 34. Then, the user adjusts the rotating plate 32 to support a suitable angle. Then, the user tightens the limiting bolt 36 on the corresponding limiting hole 35 and the rotating block 33, and then tightens the limiting nut 37 on the other end of the limiting bolt 36 to lock the angle. Next, the user passes the cable that needs support through the middle of the first lower clamping block 411 and the first upper clamping block 413. Then, by tightening the clamping nuts 414 on both sides, the first upper clamping block 413 is pressed down. The first rubber clamping blocks 415 inside the first lower clamping block 411 and the first upper clamping block 413 clamp and contact the outer wall of the cable. Then, the second upper clamping block 423 is slid upward, and the slider 424 slides in the groove 421. Another set of cables is passed through the middle of the second lower clamping block 422 and the second upper clamping block 423. Then, the clamping bolts 425 on both sides are tightened, and the second upper clamping block 423 is pressed against the second lower clamping block 422. The second rubber clamping blocks 426 inside the second lower clamping block 422 and the second upper clamping block 423 contact the outer wall of the other set of cables.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
