Description

Technical Field

[0001] The utility model relates to the technical field of power facilities, and more specifically, to a composite self-supporting cable bracket. Background Art

[0002] A self-supporting cable bracket is a device used to support and fix power cables, and has the advantages of simple structure, convenient installation, and no need for welding.

[0003] The existing self-supporting cable bracket can fix the positions of multiple cables by setting a plurality of cable clamp structures. However, since the size of the clamping cavity in the middle of the traditional cable clamp is fixed, when there is a slight difference between the diameter of the cable and the diameter of the clamping cavity, the clamping force will be insufficient, resulting in an offset phenomenon easily affected by the self-weight of the cable during high-altitude erection, causing the fixed effect of the clamping to be unstable and affecting the strength of fixing the high-altitude reinforcement position of the cable. In view of this, we propose a composite self-supporting cable bracket. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, adapt to the actual needs, and provide a composite self-supporting cable bracket to solve the technical problem that when there is a slight difference between the diameter of the cable and the diameter of the clamping cavity, the clamping force will be insufficient, resulting in an offset phenomenon easily affected by the self-weight of the cable during high-altitude erection, causing the fixed effect of the clamping to be unstable and affecting the strength of fixing the high-altitude reinforcement position of the cable.

[0005] To solve the above technical problems, the utility model provides the following technical solution: A composite self-supporting cable bracket, including a column, on the outer wall of the column, a plurality of support members are fixedly installed, on the right side of the support member, a support arm is fixedly provided, and on the top of the support arm, a plurality of cable clamp members are fixedly provided;

[0006] The cable clamp member includes a support base made of aluminum alloy, on the top of the support base, a limiting bracket made of composite material is detachably installed, and between the support base and the limiting bracket, they are connected by adjusting screws, and on the opposite sides of the support base and the limiting bracket, tightening members are fixedly provided;

[0007] The tightening member includes an arc plate fixedly connected to the support base or the limiting bracket, on the sides of both arc plates, clamping pieces inclined in the opposite direction are integrally formed, and a plurality of the clamping pieces are arranged in a circular array, and a gap is reserved between adjacent two clamping pieces.

[0008] The utility model can fix the positions of a corresponding number of cables through a plurality of cable clamps arranged at the top of the support arm. The cooperation between the support base and the limit bracket facilitates the clamping and limiting of the cables. The tightening member structures arranged on the inner walls of both can be deformed under pressure during the process of clamping the cables, thereby improving the degree of fit with the cables. This can strengthen the degree of fit between the cables and the cable clamps, so that the position can be kept stable after being clamped and fixed, and it is not easy to loosen, reducing the probability of the aerial cables deviating and strengthening the clamping force on the cables.

[0009] Preferably, a plurality of extrusion convex plates are annularly arranged on the opposite surfaces of the upper and lower clamping pieces, and the extrusion convex plates are made of metal.

[0010] Preferably, the extrusion convex plate includes a triangular plate. An arc groove is formed in the plate wall of the triangular plate, and a spike is fixedly arranged at the right-angle end of the triangular plate.

[0011] Preferably, the support member includes a connecting piece that fits with three side surfaces of the column. A limiting plate that fits with the other side surface of the column is installed on the open side of the connecting piece, and a hexagonal screw is connected between the connecting piece and the limiting plate.

[0013] Preferably, semi-circular gaskets that cooperate with the clamping pieces are fixedly arranged on the inner walls of the support base and the limit bracket, and the semi-circular gaskets are hollow cavities.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. The utility model can fix the positions of a corresponding number of cables through a plurality of cable clamps arranged at the top of the support arm. The cooperation between the support base and the limit bracket facilitates the clamping and limiting of the cables. The tightening member structures arranged on the inner walls of both can be deformed under pressure during the process of clamping the cables, thereby improving the degree of fit with the cables. This can strengthen the degree of fit between the cables and the cable clamps, so that the position can be kept stable after being clamped and fixed, and it is not easy to loosen, reducing the probability of the aerial cables deviating and strengthening the clamping force on the cables.

[0016] 2. The utility model can further limit the position of the cable through the design of the extrusion convex plate. The inclined design of the triangular plate can reduce the impact of the cable installation. When the cable in the overhead position descends and bends, it will drive the clamping part of the cable to move. In this way, under the extrusion force, the right-angle end of the triangular plate will tilt with the cooperation of the arc groove, so that the spikes on the right-angle end of the triangular plate will be tilted upward and penetrate into the outer layer of the cable, thereby achieving a locking effect. This can further improve the fixity of the cable position and is not easily affected by external forces. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The cable clamp 4 includes a support base 401 made of aluminum alloy. A composite material limit bracket 402 is detachably installed on the top of the support base 401, and the support base 401 and the limit bracket 402 are connected by adjustment screws. Tightening members 5 are fixedly provided on both opposite sides of the support base 401 and the limit bracket 402. The cooperation between the support base 401 and the limit bracket 402 is easy to fix the cable erection position. The selection of aluminum alloy material and composite material can improve the corrosion resistance characteristics, enhance the durability in the high-altitude erection environment, and is not easily corroded and damaged. The design of the tightening member 5 can further improve the fitting degree of clamping the cable, reduce the phenomenon of gaps when the size does not match, and strengthen the effect of clamping and fixing the cable.

[0024] The tightening member 5 includes an arc plate 501 fixedly connected to the support base 401 or the limit bracket 402. Clamping pieces 502 that are integrally formed on the sides of the two arc plates 501 and tilt in the opposite direction are provided, and a number of clamping pieces 502 are arranged in a circular array, and a gap is reserved between two adjacent clamping pieces 502. The arc plate 501 can fix the position of the clamping pieces 502, making the connection part have an elastic bending effect, and it is easy to tilt and flatten when the clamping pieces 502 are squeezed. The formed elastic force can keep the state of being closely attached to the cable.

[0025] In the embodiment of the present invention, a number of extrusion convex plates 6 are arranged in a circular array on the opposite sides of the upper and lower clamping pieces 502, and the material of the extrusion convex plates 6 is metal. The extrusion convex plate 6 includes a triangular plate 601. An arc groove 602 is opened on the plate wall of the triangular plate 601, and a spike 603 is fixedly provided at the right-angle end of the triangular plate 601. The shape design of the triangular plate 601 can reduce the influence on the movement of the cable when threading the cable. The opening of the arc groove 602 can form an elastic cavity. When the cable moves back, the spike 603 of the triangular plate 601 can be squeezed to tilt upward, and it can pierce into the outer layer of the cable to play a locking role.

[0026] In the embodiment of the present invention, the support member 2 includes a connecting member 201 that fits on three sides of the column 1. A limit plate 202 that fits on the other side of the column 1 is installed on the open side of the connecting member 201, and a hexagon screw 203 is connected between the connecting member 201 and the limit plate 202. The connection between the connecting member 201 and the limit plate 202 can clamp and fix on the outside of the column 1, and the cooperation with the connection of the hexagon screw 203 can complete the assembly operation.

[0027] In the embodiment of the present invention, positioning holes 101 are opened on both the left and right sides of the column 1. Positioning blocks 204 that are combined with the positioning holes 101 are fixedly provided on the opposite sides of the connecting member 201 and the limit plate 202. The connection between the positioning holes 101 and the positioning blocks 204 can limit the installation position of the support member 2, and it is not easy to have a slipping phenomenon, strengthening the stability of the cable erection height.

[0028] In an embodiment of the present utility model, semi-circular washers 403 that cooperate with the clamping pieces 502 are fixedly provided on the inner walls of the support base 401 and the limit bracket 402, and the semi-circular washers 403 are hollow cavities; they can play a supporting role when the clamping pieces 502 are squeezed and flipped, and strengthen the degree of fit between the clamping pieces 502 and the cable.

[0029] Working principle: This embodiment provides a composite self-supporting cable bracket. When erecting a cable, first adjust the distance between the support base 401 and the limit bracket 402 to expand the cable clamping cavity, making it easy for the cable to pass through. After passing through and fixing the position of the cable, the clamping cavity can be reduced by lowering the limit bracket 402, so that the tightening member 5 between the support base 401 and the limit bracket 402 can clamp the cable. During the extrusion process, the upturned part of the clamping piece 502 will be flipped under pressure, so as to be close to the position of the semi-circular washer 403, which can strengthen the degree of fit with the cable. After the cable position is fixed and clamped, the clamping stability can be maintained, and there is no easy gap. At the same time, the extrusion convex plate 6 provided on the side of the clamping piece 502 will be close to the outer layer of the cable. When the cable moves backward, the arc-shaped groove 602 opened on the triangular plate 601 can make the spike 603 provided at the right-angle end tilt upward, so that the tip pierces into the outer layer of the cable, thereby achieving a locking effect. In this way, the safety of the cable erected at a high altitude can be maintained during long-term use, and the position is not easy to shift. When the clamping piece 502 is flipped and contacts the semi-circular washer 403, it can play an elastic support effect, improve the stability of the position of the clamping piece 502, and strengthen the structural cooperation effect.

Those of ordinary skill in the art can easily understand the spirit of the present utility model based on the above embodiments and make different extensions and changes. However, as long as they do not depart from the spirit of the present utility model, they are within the protection scope of the present utility model.
