Description

Technical Field

[0001] This utility model belongs to the field of power engineering, and specifically relates to a power engineering cable support. Background Technology

[0002] In power engineering, cable supports are crucial facilities for supporting and fixing cables, and their performance directly affects the safe and stable operation of the power system. Modular fiberglass cable supports, with their lightweight, corrosion resistance, and excellent insulation properties, are widely used in underground utility tunnels, substations, cable trenches, and other similar applications. These supports typically consist of columns, brackets, and connectors, and their modular assembly allows for layered cable laying, offering advantages such as flexible installation and adaptability to various laying requirements.

[0003] However, during long-term use, the support arms of the modular FRP cable brackets, as components directly bearing the weight of the cables, are prone to cracking due to continuous stress, changes in environmental temperature, and material aging. If cracked support arms are not replaced promptly, they may lead to cable support failure, causing cable sagging, displacement, or even safety accidents. Therefore, damaged support arms must be replaced and maintained. When replacing damaged support arms of modular FRP cable brackets, since the support arms are fixed to the columns with bolts, pins, and other connectors, and the support arms typically carry multiple cables, temporary support must be provided for the cables before disassembling the damaged support arm. This temporary support process requires additional support tools, such as temporary supports and slings, which not only increases the complexity of the maintenance process and prolongs maintenance time, but may also cause secondary damage to the cables due to improper temporary support operation. Furthermore, in confined spaces such as cable trenches and pipe racks, the transportation and installation of temporary support tools are difficult, further increasing maintenance costs.

This system aims to solve the problem that, in existing technologies, when replacing damaged supports of modular fiberglass cable supports, the supports are fixed to the columns using bolts, pins, and other connectors. Since the supports typically carry multiple cables, temporary support is required before disassembling the damaged support. This temporary support process necessitates the use of additional support tools, such as temporary supports and slings. This not only increases the complexity of the maintenance process and prolongs maintenance time but also risks secondary damage to the cables due to improper temporary support operation. Furthermore, in confined spaces such as cable trenches and pipe racks, the transportation and installation of temporary support tools are difficult, further increasing maintenance costs.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention, through the provision of a disassembly and assembly mechanism, allows for the replacement of damaged support arms in a column. By rotating the first handle below the mounting plate on the left end of the support arm, the first threaded rod is removed from the mounting plate. A new support arm is then placed in front of the damaged support arm. Subsequently, the two support arms are moved backward, allowing the damaged support arm to move out of the column along the through groove on the right end, while the new support arm moves into the column along the through groove at the front end. During this movement, both support arms continuously support the cable until the new support arm is fully inside the column. Then, the first handle is reversed, causing the first threaded rod to move into the fixing hole inside the mounting plate on the left end of the new support arm. The damaged support arm, which has been removed from the column, can then be removed, completing the replacement of the damaged support arm. Furthermore, the cable receives continuous support during replacement without the need for temporary support tools, thus reducing the maintenance cost of the cable bracket.

[0018] This utility model, by setting a limiting unit, allows the cable placed on the upper end of the support arm to be restricted by the column and the inverted L-shaped baffle after the second threaded rod is rotated to move to the right end of the cable. This prevents the cable from accidentally slipping off the support arm and losing its support. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This specific embodiment is a cable support for power engineering, and its structural schematic diagram is as follows: Figures 1 to 3 As shown, the device includes a column 1, with mounting holes at both the top and bottom ends on the left side, and expansion screws slidably connected in the mounting holes. Thus, after placing the column 1 inside the wall at the installation location, the expansion screws are passed through the mounting holes and then fixed to the wall, allowing the column 1 to be secured to the wall surface.

[0027] The column 1 has an inner support arm 2 connected to its inner side. The outer end of the column 1 is equipped with a disassembly and assembly mechanism, which includes a mounting plate 301 fixedly connected to the left end of the support arm 2. An upper L-shaped plate 302 is fixedly connected at equal intervals to the inner left end of the column 1. A lower L-shaped plate 303 is fixedly connected to the inner left end of the mounting plate 301 below the upper L-shaped plate 302. Sliding grooves are provided at the front and rear ends of the column 1 at the front and rear positions of the upper L-shaped plate 302 and the lower L-shaped plate 303. A through groove is provided inside the column 1 at the right end of the sliding groove. The outer side of the upper end of the mounting plate 301 is slidably connected to the inner side of the upper L-shaped plate 302. The outer side of the lower end of the mounting plate 301 is slidably connected to the inner side of the lower L-shaped plate 303. The outer side of the mounting plate 301 is slidably connected to the inner side of the sliding groove. The outer side of the left end of the support arm 2 is slidably connected to the inner side of the through groove. A first threaded rod 304 is connected to the upper right end of the lower L-shaped plate 303. A first handle 305 is welded to the right side of the first threaded rod 304. A first threaded hole that passes through the left and right is opened at the middle position of the upper right end inside the lower L-shaped plate 303. A fixing hole that passes through the left and right is opened at the middle position of the lower part of the mounting plate 301. The outer side of the first threaded rod 304 is threaded to the inner side of the first threaded hole, and the outer side of the left end of the first threaded rod 304 is slidably connected to the inner side of the fixing hole. Thus, after the support arm 2 is slid along the through groove into the interior of the column 1, and the mounting plate 301 is slid through the groove into the interior of the column 1, the first threaded rod 304 is threaded into the first threaded hole inside the lower L-shaped plate 303 and passes through the fixing hole at the lower end of the mounting plate 301. This makes the mounting plate 301 and the lower L-shaped plate 303 relatively fixed, and the support arm 2 at the right end of the mounting plate 301 is fixed to the interior of the column 1, completing the installation of the support arm 2 inside the column 1.

[0028] Cooperate Figure 4As shown, a limiting unit is provided at the upper end of the support arm 2. The limiting unit includes an inverted L-shaped baffle 401 connected to the right side of the upper end of the support arm 2. A groove is formed on the right side of the upper end of the support arm 2, and the outer side of the lower end of the inverted L-shaped baffle 401 is slidably connected to the inner side of the groove. A bearing 402 is connected inside the upper end of the support arm 2, and a second threaded rod 403 is installed on the inner side of the bearing 402. A second handle 404 is welded to the right end of the second threaded rod 403. The bearing 402 is installed inside the support arm 2 at the middle position of the left end of the groove. A second threaded hole is formed at the middle position of the lower end of the inverted L-shaped baffle 401, and the outer side of the second threaded rod 403 is threadedly connected to the inner side of the second threaded hole. Thus, when the second handle 404 is rotated so that the second threaded rod 403 rotates in the second threaded hole inside the inverted L-shaped baffle 401, the inverted L-shaped baffle 401 can be driven to slide along the inner side of the groove, thereby changing the position of the inverted L-shaped baffle 401 on the support arm 2.

[0029] The lower side of the horizontal portion of the inverted L-shaped baffle 401 and the left side of the vertical portion of the inverted L-shaped baffle 401 abut against the outer side of the cable placed on the upper end of the support arm 2. Thus, after the cable is placed on the upper end of the support arm 2, the inverted L-shaped baffle 401 is moved to the right end of the cable by rotating the second threaded rod 403. This ensures that the left and right ends of the cable placed on the support arm 2 are restricted by the column 1 and the inverted L-shaped baffle 401, preventing the cable from accidentally slipping off the support arm 2 and losing its support.

[0030] Working principle: When replacing the damaged support arm 2 on the right end of the column 1, first turn the first handle 305 under the mounting plate 301 on the left end of the support arm 2 so that the first threaded rod 304 is removed from the mounting plate 301. Then place the new support arm 2 in front of the damaged support arm 2. Then move the two support arms 2 backward so that the damaged support arm 2 moves out of the column 1 along the through groove on the right end of the column 1. At the same time, the new support arm 2 moves into the inside of the column 1 along the through groove at the front end. While the two support arms 2 are moving, they continue to support the cable until the new support arm 2 is completely moved into the inside of the column 1. Then reverse the first handle 305 so that the first threaded rod 304 moves into the fixing hole inside the mounting plate 301 on the left end of the new support arm 2. Then remove the damaged support arm 2 that has been moved out of the column 1 to complete the replacement of the damaged support arm 2.

[0031] All technical features in this embodiment can be freely combined according to actual needs.

[0032] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
