Description

Technical Field

[0001] The utility model belongs to the technical field of cable supports, and in particular relates to a wire-laying support for high-voltage cables. Background Art

[0002] During the construction of power transmission projects, cables often need to be laid out over long distances. During the laying process, the cables are dragged along the road surface, which not only causes wear and tear on the road, but also the rubber insulation layer on the outside of the cables is damaged to varying degrees during the friction process, thus bringing potential safety hazards to the line operation. As a result, laying brackets for high-voltage cables have appeared on the market;

[0003] However, the existing pay-off bracket has a simple structure. Since the winding rollers of high-voltage cables are different, the existing pay-off bracket can only place a single winding roller. If the size of the winding roller changes, the pay-off bracket cannot be used, and its overall flexibility is poor. Utility Model Content

[0004] To solve the problems raised in the above background technology. The utility model provides a high-voltage cable pay-off bracket, comprising a bracket, and a bearing seat arranged on the top of the bracket, and also comprising a limit assembly arranged at the left end of the bracket, a rotating shaft is arranged on the bearing seat, a rotating wheel is arranged at the left end of the rotating shaft, and a pay-off bracket assembly is arranged at the right end;

[0005] The wire-releasing support assembly comprises a slide bar fixed on the rotating shaft, and a cross baffle fixed on the slide bar. A limit strip is fixed on the slide bar, and a screw is fixed on the right end of the slide bar.

[0006] As a wire-laying support for a high-voltage cable of the utility model, preferably, four limiting sliding grooves are arranged in a circular array on the cross baffle, and a limiting sliding block which slides up and down is arranged inside the limiting sliding groove.

[0007] As a wire-laying bracket for a high-voltage cable of the utility model, preferably, a top plate is fixed on the limit sliding block, a slideway is arranged at the bottom of the top plate, and a pair of limit pins are movably arranged on the slideway.

[0008] As a wire-laying bracket for a high-voltage cable of the utility model, preferably, a sleeve which slides left and right is sleeved on the sliding rod, and a limiting notch which matches the limiting strip is provided inside the sleeve.

[0009] As a wire-laying bracket for a high-voltage cable of the utility model, preferably, a locking nut is movably provided at the right end of the sleeve through a bearing, four slide plates are provided in a circular array around the outer periphery of the sleeve, and a pair of inclined grooves are obliquely provided on the slide plates.

[0010] As a wire-laying bracket for a high-voltage cable of the utility model, preferably, the slide plate matches with the slideway, and the slide plate slides left and right inside the slideway, and the inclined groove matches with the limit pin, and the limit pin slides inside the inclined groove.

[0011] As a high-voltage cable laying support of the utility model, preferably, the limiting assembly is arranged on the outer periphery of the rotating wheel, and performs a limiting operation on the rotating wheel.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The anti-loosening nut rotates on the screw rod, causing the anti-loosening nut to perform axial movement in the left and right directions, thereby driving the sleeve to slide left and right around the outside of the slide rod. At this time, the sleeve drives the slide plate to move inside the slideway. Since the limit pin is matched in the inclined groove, the top plate is pushed to move up and down, thereby adjusting the diameter of the wire-paying bracket, making it convenient to use high-voltage cable winding rollers of different sizes and improving the flexibility of the device.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example 1

[0027] like Figure 1 As shown;

[0028] A high-voltage cable pay-out support comprises a support 1 and a bearing seat 2 arranged on the top of the support 1.

[0029] In this embodiment: In order to solve the technical problems existing in the prior art, as disclosed in the background technology above, "however, the existing wire-paying bracket has a simple structure. Since the winding rollers of the high-voltage cables are different, the existing wire-paying bracket can only place a single winding roller. If the size of the winding roller changes, the wire-paying bracket cannot be used, and its overall flexibility is poor." Combined with actual use, this problem is obviously a real problem that exists and is difficult to solve. Therefore, in order to solve this technical problem, a wire-paying bracket assembly 4 is added on this basis.

[0030] like Figure 1-5 As shown in the figure;

[0031] In combination with the above content, in order to improve the flexibility of the device, it also includes a limit assembly 3 arranged at the left end of the bracket 1, a rotating shaft 21 is arranged on the bearing seat 2, a rotating wheel 22 is arranged at the left end of the rotating shaft 21, and a wire-releasing bracket assembly 4 is arranged at the right end thereof;

[0032] The wire-releasing support assembly 4 includes a slide bar 41 fixed on the rotating shaft 21 , and a cross baffle 42 fixed on the slide bar 41 . A limit strip 43 is fixed on the slide bar 41 , and a screw rod 44 is fixed on the right end of the slide bar 41 .

[0033] In an optional embodiment, four limiting grooves 421 are provided in a circular array on the cross baffle 42, a limiting slider 422 that slides up and down is provided inside the limiting groove 421, a top plate 423 is fixed on the limiting slider 422, a slideway 424 is provided at the bottom of the top plate 423, and a pair of limiting pins 425 are movably provided on the slideway 424.

[0034] In an optional embodiment, a sleeve 411 that slides left and right is sleeved on the sliding rod 41, a limiting notch 412 matching the limiting strip 43 is provided inside the sleeve 411, a locking nut 413 is movably provided at the right end of the sleeve 411 through a bearing, four slides 414 are provided in a circular array around the outside of the sleeve 411, and a pair of inclined grooves 415 are obliquely provided on the slide 414.

[0035] In an optional embodiment, the slide plate 414 matches the slideway 424, and the slide plate 414 slides left and right inside the slideway 424, the inclined groove 415 matches the limit pin 425, and the limit pin 425 slides inside the inclined groove 415, and the limit component 3 is arranged on the outer periphery of the rotating wheel 22, which performs a limit operation on the rotating wheel 22.

[0036] Working principle of this utility model:

[0037] The anti-loosening nut 413 rotates on the screw rod 44, so that the anti-loosening nut 413 performs axial movement in the left and right directions, thereby driving the sleeve 411 to slide left and right around the outer periphery of the slide rod 41. At this time, the sleeve 411 drives the slide plate 414 to move inside the slideway 424. Since the limit pin 425 matches the inclined groove 415, the top plate 423 is pushed to move in the up and down directions, thereby adjusting the diameter of the wire-releasing bracket, making it convenient to use high-voltage cable winding rollers of different sizes and improving the flexibility of the device.

[0038] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
