Description

Technical Field

[0001] The present application relates to the technical field of spacer bars, and in particular to a spacer bar for high voltage lines. Background Art

[0002] The main function of the spacer is to provide spacing and support between different wires, cables or optical cables, ensuring that they can maintain a stable position and spacing during work, thereby avoiding mutual interference and damage. It is widely used in overhead transmission lines, substations and distribution networks in power systems, as well as optical cable support and protection in the communication field.

[0003] In the related art, a spacer bar includes a frame made of non-ferromagnetic metal and four wire clamp assemblies arranged on the frame, wherein the wire clamp assembly includes a wire clamp body and a wire clamp cover hinged on the wire clamp body, one end of the wire clamp cover is hinged to the wire clamp body, and the other end of the wire clamp cover is detachably connected to the wire clamp cover through a pin and a closing pin, and the sides of the wire clamp body and the wire clamp cover that are close to each other are provided with accommodating grooves, and rubber clamping blocks are fixed on the inner side walls of the accommodating grooves by glue, and the sides of the two rubber clamping blocks that are close to each other are provided with wire clamping grooves with an arc-shaped cross-section; when supporting the cable, the cable is placed in the wire clamping groove and clamped.

[0004] In areas where wind and rain are frequent, cables supported by spacers are prone to swing frequently due to the influence of strong winds; when the cables fixed by the spacers are in a swinging state for a long time, it is easy to cause the glue fixation between the rubber clamp block and the receiving groove to fail. When it swings again subsequently, the rubber clamp block may detach from the wire clamp assembly, thereby causing the inner walls of the wire clamp body and the wire clamp cover to directly abut and wear against the cable, posing a safety hazard. Utility Model Content

[0005] The purpose of the present application is to provide a spacer rod for a high-voltage line, so as to solve the problem in the above-mentioned related art that the rubber clamp block may be detached under the influence of weather.

[0006] The present application provides a spacer bar for high voltage lines using the following technical solution:

[0007] A spacer bar for high-voltage lines, comprising a frame body and a plurality of wire clamp assemblies arranged on the frame body, the frame body comprising two supporting frames arranged opposite to each other, the wire clamp assemblies comprising a wire clamp body rotatably arranged on the supporting frames, a wire clamp cover plate installed on the wire clamp body, and an elastic clamp block; the sides of the wire clamp body and the wire clamp cover plate close to each other are both provided with accommodating grooves for inserting the elastic clamp blocks, and the sides of the elastic clamp blocks close to each other are provided with clamping grooves for fixing cables; the sides of the elastic clamp blocks away from the clamping grooves are provided with a plurality of positioning blocks, and the side walls of the accommodating grooves are provided with positioning slots for inserting the positioning blocks and placement grooves for accommodating glue.

[0008] By adopting the above technical scheme, due to the setting of the positioning plug, the positioning slot and the placement slot, when the elastic clamp is installed, the glue is injected into the placement slot in advance, and the glue is also coated on the positioning plug, and then the positioning plug on the elastic clamp is embedded in the positioning slot. After the glue hardens, the installation and fixation of the elastic clamp is achieved, which reduces the possibility of the installation of the elastic clamp becoming loose or even falling off in windy and rainy weather, and improves the installation stability of the elastic clamp.

[0009] Optionally, an adjusting member is provided on the side of the support frame, and the adjusting member includes an adjusting bolt arranged on the support frame and a limiting sleeve sleeved on the outer periphery of the adjusting bolt, and a rotating through hole for the limiting sleeve to pass through is opened on the wire clamp body.

[0010] By adopting the above technical scheme, due to the installation arrangement of the adjusting bolt and the limiting sleeve, the limiting sleeve is pre-inserted into the rotating through hole, and then the rotating through hole on the wire clamp body is placed between the two support frames, and then the adjusting bolt is used to penetrate the limiting sleeve and fix it on the support frame, thereby realizing the assembly and fixation of the support frame and the wire clamp body.

[0011] Optionally, an elliptical rubber pad is provided on the side of the wire clamp body facing the support frame, and the elliptical rubber pad is sleeved on the outer peripheral surface of the limiting sleeve.

[0012] By adopting the above technical solution, due to the installation setting of the elliptical rubber pad, the possibility of the wire clamp body being damaged by relative friction with the surface of the support frame during use is reduced, thereby increasing the service life of the wire clamp body and strengthening the protection of the wire clamp body.

[0013] Optionally, a first limiting groove for inserting the elliptical rubber pad is formed on the side of the wire clamp body facing the support frame, and a second limiting groove for inserting the elliptical rubber pad is formed on the sides of the two support frames close to each other.

[0014] By adopting the above technical solution, due to the opening of the first limit groove and the second limit groove, during the installation process of the elliptical rubber pad, its two sides are respectively inserted into the corresponding first limit groove and second limit groove, thereby reducing the possibility of the elliptical rubber pad being loose during installation during use and improving the installation stability of the elliptical rubber pad.

[0015] Optionally, a limiting protrusion located between two supporting frames is provided at the end of the wire clamp body facing the supporting frame, and limiting members located on both sides of the limiting protrusion are provided on the supporting frame, and the limiting members are used to limit the rotation range of the limiting protrusion.

[0016] By adopting the above technical solution, due to the setting of the limiting protrusion and the limiting member, the limiting member is used to limit the rotation range of the limiting protrusion, thereby reducing the rotation angle of the wire clamp body, thereby realizing the rotation limitation of the wire clamp body.

[0017] Optionally, the limiting member includes a limiting bolt arranged on the support frame and a limiting rubber sleeve sleeved on the outer periphery of the limiting bolt.

[0018] By adopting the above technical solution, when the wire clamp body rotates, the limiting protrusion will rotate to a position where the limiting rubber sleeve abuts against the outer periphery at the limit position, thereby realizing the rotation limitation of the wire clamp body.

[0019] Optionally, a limiting ring groove for the limiting protrusion to be rotatably inserted is provided on the outer periphery of the limiting rubber sleeve.

[0020] By adopting the above technical solution, when the wire clamp body rotates, the limiting protrusion will rotate into the limiting ring groove on the limiting rubber sleeve at the extreme position; the limiting is performed while the wire clamp body rotates, thereby reducing the possibility of axial deviation of the wire clamp body during rotation.

[0021] Optionally, the sides of the two support frames that are away from each other are smooth surfaces, and the sides of the two support frames that are close to each other are provided with clearance grooves.

[0022] By adopting the above technical solution, due to the setting of the smooth surface, the impact of wind on the outer surface of the support frame in windy weather is reduced; due to the setting of the yield groove on the inner side of the support frame, the raw materials used in the manufacture of the support frame are reduced, thereby reducing the production cost.

[0023] Optionally, a plurality of waist-shaped through holes are provided on the support frame, and a marking area is provided on the sides of the two support frames that are away from each other.

[0024] By adopting the above technical solution, in windy weather, due to the opening of the waist-shaped through holes on the support frame, wind can pass through the waist-shaped through holes, further reducing the impact force of the wind on the support frame; when installing the spacer bar frame, it is installed according to the direction indicated by the marking area, which can ensure the correct installation position of the support frame and avoid installation errors or inversion.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. Due to the setting of the positioning plug, the positioning slot and the placement slot, when the elastic clamp is installed, glue is injected into the placement slot in advance, and the glue is also applied to the positioning plug, and then the positioning plug on the elastic clamp is embedded in the positioning slot. After the glue hardens, the installation and fixation of the elastic clamp is realized, which reduces the possibility of loosening or even falling off of the elastic clamp in windy and rainy weather, and improves the installation stability of the elastic clamp.

[0027] 2. Due to the installation of the elliptical rubber pad, the possibility of the wire clamp body being damaged by relative friction with the surface of the support frame during use is reduced, thereby increasing the service life of the wire clamp body and strengthening the protection of the wire clamp body.

[0028] 3. Due to the setting of the smooth surface, the impact of wind on the outer surface of the support frame in windy weather is reduced; when installing the spacer frame, install it according to the direction indicated by the marking area to ensure the correct installation position of the support frame and avoid installation errors or inversion.
