Description

Technical Field

[0001] The utility model relates to the technical field of cable laying, in particular to a supporting component for cable laying. Background Art

[0002] A cable is an electrical energy or signal transmission device, usually consisting of several or several groups of conductors twisted together into a rope-like form. Cables are mostly laid in places such as cable trenches or tunnels, and usually require cable support frames for support. Prefabricated frames are more commonly used. Cable supports are installed directly on site before or during cable laying, and are usually installed with expansion bolts to the surrounding environment. The cables are placed directly on the support arms of the support frames to support the cables. Although this is convenient and quick, there is no limit between the cables and the support frames during cable laying, and the cables are very easy to slip off. The cables that have slipped off need to be re-installed on the support frames, and when multiple cables are laid, different cables need to be bundled and fixed, otherwise the cables that are not provided will resist each other, causing the cables to be suspended and the support frames to lose their supporting function. Therefore, the existing support frames are less practical. Utility Model Content

[0003] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a support assembly for laying cables.

[0028] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0029] Example

[0030] As mentioned in the background technology, the existing cable support frame has many disadvantages when used on the walls of tunnels, etc. Although it is convenient to directly lay the cables on the support arm 3, it is very easy for the cables to slip, and they need to be repeatedly re-laid, and they may slip out of place over a long period of time. Secondly, when multiple cables are laid on one support arm 3, there will be resistance between them, causing the cables to be suspended in the air and the support arm 3 to lose its supporting function. The inventor has made improvements on the existing support frame and designed a new type of support component for cable laying, which is described in detail below with reference to the drawings.

[0031] This embodiment provides a support assembly for laying cables, see Figure 1, including a column 1, which is in the shape of a plate and can be installed in an external support such as a tunnel wall by means of expansion bolts, and the height of the column 1 should be higher than the height of the cable to be laid. Secondly, a plurality of mounting seats 2 are installed at intervals from top to bottom on the column 1, and the height of the intervals can be the same or determined according to the actual laying conditions of cables at different heights. On the basis of the above structure, a plurality of mounting seats 2 are fixedly installed with a support arm 3 on one side away from the column 1, which can support the cable, and the support arm 3 extends in a direction away from the column 1. The purpose of the extension is to ensure that multiple cables can be supported, thereby expanding the scope of use of the present solution, and the fixed installation of the support arm 3 means that the support arm 3 is fixed during use, but can still be disassembled from the column 1.

[0032] Specifically, the side of the mounting seat 2 is provided with a mounting groove 6, combined with Figure 4 , and one end of the support arm 3 can be inserted into the mounting groove 6 and fixed with bolts. The mounting groove 6 is opened toward one side of the support arm 3, and the side close to the support arm 3 is open. The width is consistent with the thickness of the support arm 3. A part of the support arm 3 can be inserted into the mounting groove 6, and the bolts penetrate the two to complete the fixation. Secondly, in order to improve the supporting strength of the support arm 3 to the cable, the bottom surface of the support arm 3 is set to be inclined, and the end close to the mounting seat 2 is inclined downward, that is, the front view of the support arm 3 is a triangle near the bottom, which can reduce the weight of the support arm 3 while improving the support stability, and the fixing position of the bolt should be close to the upper end surface of the support arm 3.

[0033] As one of the main technical points of the utility model, Figure 1 and Figure 2 The mounting seat 2 is detachably mounted with a clamping arm 4 on the same side thereof, and the clamping arm 4 is located above the bracket arm 3 and also extends in a direction away from the mounting seat 2. The length of the clamping arm 4 is consistent with the length of the bracket arm 3. In order to facilitate the placement of the cable, the clamping arm 4 is detachably mounted. Specifically, in combination with Figure 3 and Figure 4 A slot 7 is also provided on the side of the mounting seat 2, and the upper end is open. The slot 7 is located above the mounting slot 6, and the slot 7 is convex. An insert block 8 that can slide up and down along the slot 7 is provided at one end of the clamping arm 4. In order to improve the stability during sliding, two slots 7 and insert blocks 8 are provided. When the clamping arm 4 needs to be disassembled and installed, the clamping arm 4 can be slid upward or downward, and the insert block 8 moves up and down in the slot 7 until the insert block 8 slides out above the slot 7 or enters the slot 7.

[0034] Based on the above structure, combined with Figure 2The clamping arm 4 can be connected and fixed with the supporting arm 3, so that the cable placed on the supporting arm 3 can be clamped. Specifically, the clamping arm 4 is connected to the supporting arm 3 by a fastener 5, and the fastener 5 can push the clamping arm 4 to move toward the direction close to the supporting arm 3, so as to clamp the cable on the supporting arm 3. In order to improve the fixing effect of the fastener 5 on the two, two groups of fasteners 5 are provided, and are respectively located at both ends of the supporting arm 3, so that both ends of the supporting arm 3 and the clamping arm 4 can be fixed.

[0035] Specifically, the fastener 5 includes a fastening bolt 51 connected to the clamping arm 4, the fastening bolt 51 has a threaded end arranged toward the clamping arm 4, and a channel 9 for the fastening bolt 51 to pass through is opened on the clamping arm 4, the diameter of the channel 9 is larger than the outer diameter of the threaded part of the fastening bolt 51, and a nut 52 threadedly connected to the fastening bolt 51 is arranged above the clamping arm 4. The nut 52 can be a butterfly nut 52 for easy rotation. After placing the cable on the support arm 3, the clamping arm 4 is installed on the side of the mounting seat 2, the fastening bolt 51 passes through the clamping arm 4, and the nut 52 is installed on the upper end. By rotating the nut 52 downward, the clamping arm 4 is pushed downward to clamp the cable.

[0036] On the basis of the above structure, when the cable is placed on the support arm 3, in order to ensure its stability, a plurality of brackets 10 are provided on the upper end surface of the support arm 3 along the length direction, and the brackets 10 are arranged in an arc shape, which can be adapted to the outer edge of the cable. Correspondingly, a plurality of clamping grooves 11 are provided on the clamping arm 4 corresponding to the plurality of brackets 10, and the clamping grooves 11 are arranged in an arc shape accordingly. The clamping grooves 11 correspond one-to-one with the brackets 10, and can be adapted to the plurality of cables on the support arm 3. When the clamping arm 4 moves downward to clamp, the clamping grooves 11 can be adapted to the outer edge surface of the cable, thereby expanding the contact area between the two and ensuring stability during clamping.

[0037] Furthermore, in order to protect the outer end surface of the cable and prevent the compression groove 11 from directly compressing the cable and causing damage to the cable, an arc plate 12 is arranged in the compression groove 11, and the arc plate 12 is connected to the top of the compression groove 11 through a support spring 13, and the central angle of the arc plate 12 is set to 30°-180° to ensure that it can adapt to the use of cables with different outer diameters. By setting the arc plate 12, the arc plate 12 can directly contact the cable when the compression arm 4 is compressed. By setting the support spring 13, there is a certain buffer between the cable and the compression groove 11, so as to avoid a large impact when the cable shakes, which causes wear between the cable and the compression groove 11.
