Description

Technical Field

[0001] This utility model relates to the field of power construction technology, specifically to a cable support for power construction. Background Technology

[0002] In the process of power construction, cable brackets are important components used to support, fix and arrange cables. Their layout method is directly related to the operational safety and service life of the cables. Most of the commonly used cable brackets adopt straight through hole type or straight pressure groove type structure. The cable crosses the bracket in a straight line and is fixed by binding straps, pressure plates or buckles. Although this type of structure is simple to process and quick to install, it still has shortcomings in complex construction environments.

[0003] When a cable crosses a support in a straight line, the stress points are mainly concentrated at the local compression points, which can easily cause indentations on the cable sheath or damage to the insulation layer. In long-term operation, this may also lead to stress concentration and premature aging of the cable. Therefore, a cable support for power construction is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a cable support for power construction to solve the problems mentioned in the background art.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] Example

[0029] Please see Figures 1-4 This utility model provides a technical solution: a cable bracket for power construction, including two supports 10, which are used to be installed on a wall or support surface to serve as the load-bearing reference for the entire device.

[0030] In this embodiment, specifically: a reinforcing frame 14 is provided on one side of the support 10, the reinforcing frame 14 plays a reinforcing role, and a main mounting frame 15 is fixedly connected to the end of the reinforcing frame 14 away from the support 10. A secondary mounting frame 16 is provided on one side of the main mounting frame 15. The main mounting frame 15 and the secondary mounting frame 16 are arranged in parallel to each other and are used to jointly support the cable protection mechanism.

[0031] In this embodiment, specifically: threaded tubes 17 are installed at opposite ends of the main mounting bracket 15 and the sub-mounting bracket 16. A threaded rod 18 is fixedly connected to the end of the sub-mounting bracket 16 near the threaded tube 17. The threaded rod 18 is threadedly engaged with the threaded tube 17, so that the main mounting bracket 15 and the sub-mounting bracket 16 can be reliably connected and disassembled in the axial direction by threaded engagement. The sub-mounting bracket 16 has a threaded tube 17 and a threaded rod 18 at both ends, which can be combined and increased according to the number of cables.

[0032] In this embodiment, specifically: a cable protection mechanism is provided on both the main mounting frame 15 and the auxiliary mounting frame 16. The cable protection mechanism includes a fixing block 20, which is fixed to the main mounting frame 15 by fastening bolts 23. A threaded hole 151 is provided on the main mounting frame 15, and the fastening bolt 23 is threaded into the threaded hole 151 and fastened to the fixing block 20, so that the fixing block 20 can be stably installed on the main mounting frame 15.

[0033] In this embodiment, specifically: an S-shaped cable protection tube 21 is fixedly installed through the middle of the fixing block 20. When the cable is laid, it is passed through the S-shaped cable protection tube 21 to form a transition path with buffer and bend limit, so as to avoid stress concentration when the cable is bent at a right angle or suspended across the air.

[0034] In this embodiment, specifically: a fastener 22 is provided on the outer side of the threaded rod 18, and a knob 24 is fixedly connected to the end of the threaded rod 18. The knob 24 is used for manual tightening, which can be operated by construction personnel without tools. When the threaded rod 18 is rotated by the knob 24, the threaded rod 18, through the cooperation between the fastener 22 and the fixing block 20, causes the fixing block 20 to change the angle position of the S-shaped cable protection tube 21. When laying cables, construction personnel can first pass the cable through the S-shaped cable protection tube 21, and then operate the threaded rod 18 by tightening the knob 24 according to the actual direction of the cable, thereby driving the S-shaped cable protection tube 21 to adjust its angle so that it can adapt to the tilt direction of the cable and avoid the cable being forcibly twisted.

[0035] In this embodiment, specifically: the dovetail cone plate 32 is composed of multiple rubber plates arranged in sequence along the circumference and has elastic deformation capability. When cables of different diameters are inserted, the rubber plates can deform accordingly to adaptively tighten the cables, thereby avoiding installation limitations caused by differences in cable diameter.

[0036] In this embodiment, specifically: sliding holes are provided on the adjacent sides of the two supports 10, and sliding rods 11 are slidably installed in the sliding holes. Slide seats 12 are provided on the front side of the two supports 10, and sliding plates 13 are slidably installed between the two slide seats 12. The two ends of the sliding plates 13 are fixed with screws. During installation, the sliding plates 13 can be adjusted in position within the slide seats 12. After the construction personnel determine the appropriate position, they reinforce it with screws to keep the support 10 as a whole stable.

[0037] In this embodiment, specifically: the slide plate 13 is fixedly connected to one end of the reinforcing frame 14 by screws. After the reinforcing frame 14 is connected to the main mounting frame 15, it not only plays a reinforcing role, but also allows the positions of the main mounting frame 15 and the auxiliary mounting frame 16 to be adjusted relative to the support 10 at an angle.

[0038] The specific methods are as follows:

[0039] In this embodiment, specifically: the installation method of the support 10 changes: the support 10 can be installed horizontally or vertically according to the site conditions. When the installation direction of the support 10 changes, the installation direction of the connecting reinforcing frame 14, main mounting frame 15 and auxiliary mounting frame 16 will also change accordingly, so as to adapt to different directions of the cable in vertical or horizontal layout.

[0040] In this embodiment, specifically: the spacing between the supports 10 is adjusted: the two supports 10 are connected by a sliding rod 11, which can slide in the sliding hole, so that the spacing between the two supports 10 is adjustable. During construction, the spacing between the supports 10 can be adjusted according to different requirements of the installation position, and the structure is kept stable by the fixing effect of the sliding plate 13.

[0041] In this embodiment, specifically: the angle adjustment of the reinforcing frame 14: with the support 10 remaining unchanged, the construction personnel can also adjust the installation angle of the sliding plate 13 and the reinforcing frame 14, thereby changing the tilt direction of the main mounting frame 15 and the auxiliary mounting frame 16, which can also make the angle of the subsequent cable protection mechanism and the S-shaped cable protection tube 21 match the actual cable laying angle, thereby avoiding the cable being forced to bend or twist.

[0042] In this embodiment, specifically: through the above structural settings, the present invention can be adjusted in multiple dimensions, including the installation direction of the support 10, the spacing between the supports 10, and the angle of the reinforcing frame 14, so that the cable bracket can flexibly adapt to the cable routing in different construction environments.

[0043] Working principle: Construction personnel select a suitable installation method according to the cable construction environment, and fix the two supports 10 to the wall, cable tray or other load-bearing surface by means of expansion bolts or welding. The supports 10 can be installed horizontally or vertically, so that the subsequent reinforcing frame 14, main mounting frame 15 and auxiliary mounting frame 16 can be laid out in the horizontal or vertical direction respectively, to meet the installation requirements of the cable in different directions.

[0044] The two supports 10 are connected by a sliding rod 11, which can slide in the sliding hole, so that the distance between the two supports 10 can be flexibly adjusted. After the construction personnel determine the cable laying width, they fix the position of the two supports 10 by using the sliding block 12 and the sliding plate 13, and tighten the screws at both ends of the sliding plate 13 so that the sliding plate 13 is locked in the sliding block 12, thereby ensuring the installation stability of the overall bracket.

[0045] Then, the construction workers connect the reinforcing frame 14 to one end of the sliding plate 13 with screws and fix it to the main mounting frame 15. Since the connection angle between the reinforcing frame 14 and the sliding plate 13 is adjustable, the construction workers can adjust the angle of the reinforcing frame 14 according to the specific route of the cable on site, thereby causing the direction of the main mounting frame 15 and the auxiliary mounting frame 16 to change, so that the installation angle of the cable protection mechanism is consistent with the actual cable entry direction, avoiding unnecessary bending or twisting of the cable during the installation process.

[0046] After the installation of the above-mentioned support parts is completed, the construction personnel will pass the cable through the S-shaped cable protection tube 21 set on the main mounting frame 15 and the auxiliary mounting frame 16 in sequence. The S-shaped cable protection tube 21 passes through the fixing block 20 and forms a curved channel inside, so that the cable forms a smooth S-shaped transition when it is passed through. This transition structure can effectively limit the bending radius of the cable, avoid stress concentration caused by right angle bends or suspended crossings, and at the same time disperse the tension of the cable and reduce the risk of uneven stress on the outer sheath.

[0047] After the cable is installed, the construction personnel operate the knob 24 located at the end of the threaded rod 18. When the knob 24 is turned, it drives the threaded rod 18 to rotate. The threaded rod 18, through the cooperation between the outer fastener 22 and the fixing block 20, causes the fixing block 20 to drive the S-shaped cable protection tube 21 to change its angle within a certain range, thereby adjusting the tilt angle of the S-shaped cable protection tube 21. Through this operation, the construction personnel can match the outgoing direction of the S-shaped cable protection tube 21 with the actual tilt direction of the cable, avoid the cable being forcibly twisted, and improve the flexibility of installation.

[0048] Once the cable is positioned appropriately within the S-shaped cable conduit 21, the construction personnel clamp and fix the cable end using the connector tube 30 and the fixing cap 33. The connector tube 30 has a tapered tube 31 inside, and the fixing cap 33 is connected to the port of the connector tube 30 via threads. A dovetail cone plate 32 is installed inside the fixing cap 33. During the tightening of the fixing cap 33, the dovetail cone plate 32 is inserted into the tapered tube 31 and gradually converges radially inward after being squeezed by the cone surface, thus adhering tightly to the outer wall of the cable and achieving reliable fixing of the cable end.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
