Description

Technical Field

[0001] The utility model relates to the technical field of cable installation supports, in particular to a high-strength aluminum alloy channel bracket. Background Technique

[0002] With the development of urban cable transmission, cable supports are used more and more widely. However, due to the relatively simple processing of this product in the past, it was either welded with ordinary round steel, angle steel, or channel steel, or some were made in a flanging mode. So far, there has not yet formed a standard, universal, and industrialized system. As a support for cables, cable supports mainly play the role of fixing and stabilizing the cables during cable laying and operation, making the cable routing clear, and the installation firm. Only requires the support to have a certain load-bearing strength, and at the same time, there should be a fixture installation position for fixing the cable. On the premise of meeting the strength, the main function of the support is to be able to install the fixture to fix the cable. The main purpose of the fixture installation is on the one hand to fix the cable, so that the cable will not short-circuit or vibrate during operation, causing the cable to slide or move, and at the same time making the cable routing clear for easy operation and maintenance.

[0003] Looking at the existing non-magnetic supports, there are generally stainless steel supports and composite material supports. In recent years, due to the large dispersion of composite supports and the difficulty in controlling the quality, it is difficult to promote them comprehensively. And stainless steel supports will generate magnetism during the processing, so demagnetization treatment is required. Also, stainless steel supports have a large specific gravity and are heavy, which brings inconvenience to the installation in the narrow space of cable structures. Content of the Utility Model

[0004] The utility model provides a high-strength aluminum alloy channel bracket, aiming to solve the problem that the installation fixtures of cable brackets generally have bolt holes on the brackets. Then, due to the lack of unified national regulations on the specifications and models of cable fixtures and the non-uniformity of cable specifications and models, many hole distances need to be customized, resulting in poor universality of the product.

[0005] The utility model is realized as follows. A high-strength aluminum alloy channel bracket includes a column and a support arm. On one side of the column close to the support arm, there are two first channel structures arranged in parallel. At one end of the support arm close to the column, there is a flange end plate. The side of the flange end plate close to the column is movably connected to the column through the first channel structure. On the upper part of the support arm, there is a second channel structure. The upper part of the support arm is movably connected with a cable clamp seat through the second channel structure. The upper part of the cable clamp seat is movably connected with a clamp cover. Inside the cable clamp seat and the flange end plate, there is a connecting bolt rotatably connected. On the outer side of the connecting bolt, there is a connecting nut threadedly connected. On the side of the connecting bolt away from the connecting nut, there is a T-shaped nut anti-slip block bolted. The T-shaped nut anti-slip block is slidably connected to the column through the first channel structure and slidably connected to the support arm through the second channel structure. On both sides of the column away from the support arm, there are convex edges, and the column and the convex edges are integrally formed.

[0006] In order to achieve the effect of facilitating the installation of the structure without drilling holes, as an optimization of the high-strength aluminum alloy channel bracket of the utility model, the connecting bolt is a T-shaped bolt, and the connecting nut is a flange nut.

[0007] In order to achieve the effect of ensuring the structural strength, as an optimization of the high-strength aluminum alloy channel bracket of the utility model, the column is made of 45# steel material, and saw teeth are arranged on the inner side of the channel structure.

[0008] In order to achieve the effect of making the structure not easily generate magnetism, as an optimization of the high-strength aluminum alloy channel bracket of the utility model, the support arm is made of aluminum alloy material, and the support arm adopts an I-shaped structure.

[0009] In order to achieve the effect of strengthening the stress intensity at the stress position, as an optimization of the high-strength aluminum alloy channel bracket of the utility model, the side of the support arm close to the column is thickened and heightened, and the whole shows a conical shape.

[0010] In order to achieve the effect that the support arm is not easily slid down when bearing weight, as an optimization of the high-strength aluminum alloy channel bracket of the utility model, a special T-shaped nut is equipped. Saw teeth are arranged on the outer side of the T-shaped nut anti-slip block, and the saw teeth on the outer side of the T-shaped nut anti-slip block and the saw teeth on the inner side of the channel structure are used in cooperation.

[0011] In order to adjust the spacing of the cable clamp seat, the spacing of the cable clamp seat can be adjusted on the support arm through the connecting bolt.

[0012] In order to adjust the height of the support arm, the height on the column of the flange end plate can be adjusted by adjusting the connecting bolt, so as to complete the height adjustment.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] This bracket can be directly embedded in the structure, which can make the remaining space of the limited structure larger. In cable structures, especially cable trenches and cable tunnels, the underground space is limited. Embedding the columns in the structure can reduce the space occupied by the columns in the structure, avoiding the problems in the prior art where the columns are welded after the structure is completed or fixed by using expansion bolts. This not only involves a large amount of work, but sometimes it also damages the structure. When drilling holes for expansion bolts, it may hit the reinforcing bars of the structure, causing installation difficulties.

[0015] Due to the embedded type, the column can be welded to the reinforcing bar through a T-shaped steel nail, making the column and the structure an integral whole, with higher strength and enhanced anti-corrosion protection. The column is embedded in the structure, and its protective performance is fully protected. The vertical distance between the cantilever arms is highly adjustable. Due to the use of a channel structure, the vertical distance between the cantilever arms can be arbitrarily adjusted by sliding the T-nut anti-sliding block inside the channel structure, without being affected by the original hole spacing of the column. After installation, the cable can be installed and fixed through the clamp cover and the cable clamp seat.

[0016] This bracket is particularly suitable for the operation support of extra-high voltage single-core cables, which requires non-magnetic and high strength characteristics. Therefore, choosing high-strength aluminum alloy has certain advantages in the material selection and process forming of this bracket, and its structural strength can exceed that of A3 steel and stainless steel.

[0027] Please refer to Figure 1-7 , the present utility model provides a technical solution: a high-strength aluminum alloy channel bracket, which includes a column 1 and a support arm 2. Two parallel first channel structures 6 are provided on one side of the column 1 close to the support arm 2. A flange end plate 5 is provided at one end of the support arm 2 close to the column 1. The side of the flange end plate 5 close to the column 1 is movably connected to the column 1 through the first channel structure 6. A second channel structure 11 is provided on the upper part of the support arm 2. A cable clamp seat 3 is movably connected to the upper part of the support arm 2 through the second channel structure 11. A clamp cover 4 is movably connected to the upper part of the cable clamp seat 3. Connecting bolts 9 are rotatably connected to the inner sides of the cable clamp seat 3 and the flange end plate 5. Connecting nuts 7 are threadedly connected to the outer sides of the connecting bolts 9. A T-shaped nut anti-slip block 8 is bolted to the side of the connecting bolt 9 away from the connecting nut 7. The T-shaped nut anti-slip block 8 is slidably connected to the column 1 through the first channel structure 6. The T-shaped nut anti-slip block 8 is slidably connected to the support arm 2 through the second channel structure 11.

The column 1 is pre-embedded in the structure, which can reduce the space occupied by the column 1 in the structure. It avoids the problems in the prior art where the column 1 is welded after the structure is completed or fixed by using expansion bolts. This not only involves a large amount of work, but sometimes also damages the structure. When drilling expansion bolt holes, it may encounter the reinforcing bars of the structure, causing installation difficulties. Since it adopts the pre-embedded type, the column 1 can be welded to the reinforcing bars through T-shaped steel nails, making the column 1 and the structure an integral whole, with higher strength and increased anti-corrosion protection. The column 1 is pre-embedded in the structure, and its protection performance is fully protected. The vertical distance between the brackets 2 is highly adjustable. Due to the adoption of the channel structure 6, the vertical distance of the brackets 2 can be arbitrarily adjusted by sliding the T-nut anti-slip block 8 inside the channel structure 6, without being affected by the original hole spacing of the column 1. After installation, the cable can be installed and fixed through the clamp cover 4 and the cable clamp seat 3. By setting the convex rib 10, the column 1 can be lifted, reducing the contact area with the installation surface and avoiding the trouble caused by the bottom surface not fitting when installing on an uneven wall surface.

[0030] In this embodiment: the clamp cover 4 and the cable clamp seat 3 used for cable fixing are fixed to the bracket 2 through the T-shaped bolt as the connecting bolt 9, eliminating the trouble of drilling holes according to the bolt distance of the original cable clamp. At the same time, the channel structure 6 is of a full length, and the fixing position can be arbitrary, without the need to customize the bolt holes on the bracket 2 according to different clamp hole distances.

[0031] As a technical optimization scheme of the present utility model, the column 1 is made of 45# steel, and sawteeth are provided on the inner side of the channel structure 6.

[0032] In this embodiment: the column 1 made of 45# steel has sufficient strength and ensures the service life of the structure after pre-embedding. The sawteeth on the inner side of the channel structure 6 can prevent the bracket 2 from slipping under the condition of bearing weight, avoiding the structure from sliding down.

[0035] As a technical optimization scheme of the present utility model, the side of the bracket 2 close to the column 1 is thickened and heightened, and the whole shows a conical shape.

[0036] In this embodiment: By thickening and heightening at the stressed part and thinning and shortening at the top, the use of materials can be reduced while enhancing the stress resistance.

[0037] As a technical optimization solution of the present utility model, sawteeth are provided on the outer side of the T-shaped nut anti-slip block 8, and the sawteeth on the outer side of the T-shaped nut anti-slip block 8 are used in cooperation with the sawteeth on the inner side of the channel structure 6.

[0038] In this embodiment: The sawteeth provided on the outer side of the T-shaped nut anti-slip block 8 can cooperate with the sawteeth on the inner side of the channel structure 6, and the sawteeth can be engaged with each other when the T-shaped nut anti-slip block 8 is fixed, so as to fix the structure.

[0039] In this embodiment: The cable fixture seat 3 can be adjusted in distance on the support arm 2 through the connecting bolt 9.

[0040] In this embodiment: The flange end plate 5 can be adjusted in the up-and-down height on the column 1 through the connecting bolt 9.

[0041] Working principle: First, the bracket can be installed by embedding. The adaptability of cable fixing is stronger. Due to the adoption of the channel structure 6, the clamp cover 4 and the cable fixture seat 3 for cable fixing are fixed to the support arm 2 through T-shaped bolts, so there is no need for the trouble of drilling holes according to the bolt distance of the cable fixture. At the same time, the channel structure 6 is of full length, and the fixing position can be arbitrary. There is no need to customize the fixing bolt holes on the support arm 2 according to the hole distances of different clamps, which is convenient for flexible fixing of the clamp, enables the cable fixture seat 3 to move horizontally on the support arm 2, increases the convenience for horizontal serpentine laying, and at the same time, an axial slideway is added on the channel structure 6 to perform flexible fixing for vertical serpentine laying.
