Technical Field

[0001] The utility model relates to the technical field of cable brackets, and specifically relates to a cable bracket convenient for pulling cables. Background Art

[0002] A cable is usually a rope-like device formed by stranding several or several groups of wires. Each group of wires is insulated from each other and is often twisted around a central wire. The outer wall of the entire inner wire is covered with a highly insulating covering layer. A cable has the characteristics of being energized inside and insulated outside. Cables are mostly erected in the air or installed underground or underwater for telecommunications or power transmission. Cable brackets are used to support cables when erecting cables.

[0003] Traditional cable brackets generally only have a simple support function, such as a hot-dip galvanized expandable splicing cable bracket disclosed in the publication number CN217159146U. However, when pulling cables during the cable erection process, the friction between traditional cable brackets and cable brackets is relatively large, which is not conducive to pulling cables during cable erection, and the cable brackets are prone to damaging the cables during the cable pulling process.

[0017] The present utility model will be further described below with reference to the drawings and embodiments.

[0018] As Figure 1 , Figure 2 shown, the cable support for facilitating cable pulling of the present utility model includes a vertical rod 1. At least one support roller 3 for supporting the cable is provided on the vertical rod 1. The support roller 3 is disposed in a direction perpendicular to the vertical rod 1, such that the axis of the support roller 3 is perpendicular to the vertical rod 1. The support roller 3 is rotatably disposed on the vertical rod 1 through a support roller mounting frame 2 provided on the vertical rod 1. A cable limiting groove 31 is provided on the support roller 3. It can be understood that the support roller 3 can be rotatably connected to the support roller mounting frame 2 through a bearing.

[0019] When the cable support of the present utility model is in use, it is fixed on the foundation through the vertical rod 1. The cable 5 is placed in the cable limiting groove 31 provided on the support roller 3, and the position of the cable is restricted by the cable limiting groove 31 to prevent it from moving out of the support roller 3. Since the cable support of the present utility model is provided with a rotatable support roller 3 on the vertical rod 1, the cable can be supported by the support roller 3, and the support roller 3 can rotate. During the process of erecting the guy wire, the cable can cause the support roller 3 to rotate through friction, which is convenient for the cable to move forward. The friction between the cable and the support roller 3 is small, which is convenient for cable erection and can reduce cable damage.

[0020] As Figure 2 shown, in order to better support the cable, preferably, at least two support rollers 3 for supporting the cable are provided on the vertical rod 1, and the support rollers 3 are arranged horizontally side by side. The cable is supported by multiple support rollers 3, and the support area is larger, which can better support the cable. Figure 2 In it, 3 support rollers 3 arranged horizontally side by side are provided on the vertical rod 1 to support the cable.

[0021] The support roller mounting frame 2 can be connected to the vertical rod 1 by welding, bolt connection, etc., and the height of the support roller mounting frame 2 is not adjustable. Of course, the support roller mounting frame 2 can also be connected to the vertical rod 1 in a height-adjustable manner. Since during the construction process, it is usually necessary to ensure that the support rollers 3 of each cable support are at the design elevation, but it is generally difficult to accurately locate the installation position of the cable support during the installation process. Therefore, in order to conveniently fine-tune the height of the support roller 3 according to the actual situation, preferably, the support roller mounting frame 2 is connected to the vertical rod 1 in a height-adjustable manner. Specifically, the support roller mounting frame 2 is vertically slidably connected to the vertical rod 1, and a locking mechanism for locking the position of the support roller mounting frame 2 is provided on the vertical rod 1.

[0022] When the elevation of the support roller 3 needs to be adjusted after the cable support is installed, slide the support roller mounting frame 2 up or down along the vertical rod to an appropriate position, and then lock the position of the support roller mounting frame 2 through the locking mechanism. The support roller mounting frame 2 is connected to the vertical rod 1 in a height-adjustable manner, which reduces the requirement for the installation positioning accuracy of the cable support, can reduce the installation difficulty of the cable support, and can adjust the support height of the cable support according to the situation of the installation position.

[0023] Specifically, as Figure 1As shown, the support roller mounting bracket 2 is provided with a vertical insertion portion 21. The upper end of the vertical rod 1 is provided with a vertical insertion hole. The lower end of the insertion portion 21 is inserted into the insertion hole and is in sliding fit with the insertion hole, so as to realize vertical sliding connection with the vertical rod 1. The insertion portion 21 is provided with a plurality of through holes 22 extending horizontally. The through holes 22 are arranged at intervals vertically along the insertion portion 21. The locking mechanism is a screw rod 4 inserted on the vertical rod 1 and in plug-in fit with the through holes 22 so as to be able to pass through the through holes. The through holes 22 extend horizontally, that is, the axis of the through holes 22 is perpendicular to the extension direction of the insertion portion 21. When it is necessary to adjust the height of the support roller 3, slide the support roller mounting bracket 2 up or down along the vertical rod to an appropriate position, and then insert the screw rod 4 into the corresponding through hole 22 to lock the position of the support roller mounting bracket 2.

[0024] In some embodiments, the locking mechanism also uses a pin. In some embodiments, the support roller mounting bracket 2 is slidably connected to the vertical rod 1 through two vertical guide rails provided on the vertical rod 1.

[0025] In order to facilitate the installation and fixation of the cable bracket, in the present utility model, the lower end of the vertical rod 1 is provided with a pile tip, and the outer periphery of the vertical rod 1 is provided with a thread.

[0026] For the cables on the cable bracket, especially the cables on the cable bracket installed at the slope, it is easy to slide downward under the action of gravity. Therefore, in order to better fix the cables after the cable laying is completed and prevent the cables from sliding, the present utility model is provided with a pressing plate 6 above the cable limiting groove 31 for pressing the cables in the cable limiting groove 31. The pressing plate 6 can be one or more. The support roller mounting bracket 2 is provided with a top rod 7 arranged vertically and located above the pressing plate 6. One end of the top rod 7 is threadedly connected to the support roller mounting bracket 2 through the thread on its outer periphery, and the other end is rotatably connected to the pressing plate 6. In this way, after the cable laying and pulling are completed, the top rod 7 can be screwed to move the top rod 7 downward, so that the pressing plate 6 can be pushed downward by the top rod 7 to press the cables in the cable limiting groove 31 and fix the cables in the cable limiting groove 31. The pressing plate 6 can be made of plates of various materials, such as: steel plates, plastic plates or rubber plates, etc. In order to protect the cables, in the present utility model, the pressing plate 6 is preferably a rubber plate.
