Description

Technical Field

[0001] The utility model relates to the technical field of cable support structures, in particular to a cable bracket for transmission lines. Background Art

[0002] Transmission cables refer to power cables, which are cables used to transmit and distribute electrical energy. Power cables are commonly used in urban underground power grids, power station lead-out lines, internal power supply for industrial and mining enterprises, and underwater transmission lines across rivers and seas. Transmission lines are usually laid in cable trenches and tunnels, and are generally fixed using cable brackets;

[0003] The utility model with the search announcement number CN220544671U specifically discloses a transmission line cable bracket, which adopts a fixing structure 1, a fixing structure 2, a tightening structure and a rolling structure, solves the problem that the outer skin of the transmission cable is easily damaged during the dragging process and the cable installed in the front is easily loosened, and achieves the effect of facilitating the adjustment of the height of the cable bracket according to needs, facilitating the prevention of damage to the outer skin of the transmission cable during the dragging process, and facilitating the fixing of the transmission cable in a limited position;

[0004] Although the device solves the wear problem of the fixed structure during the towing of the transmission line during use, it is mainly achieved through the transmission cable roller. After the cable is arranged, the transmission cable roller needs to be fixed and limited. The device is mainly implemented by threaded connection of threaded rods. The subsequent cables are affected by the surrounding environment during use. For example, in a subway tunnel, the cables are very likely to be affected by the vibration generated during the operation of the subway, causing the cables to shake, so that the connection between the transmission cable roller and the threaded rod is affected by the pulling force of the cable shaking. If used in this environment for a long time, it is very easy to cause the force concentration at the connection of the threaded rod, causing the threaded rod to deform or even break, resulting in the loosening of the cable.

[0005] To this end, a cable support for a transmission line is proposed. Utility Model Content

[0026] See also Figures 1 to 5 , the utility model provides a technical solution:

[0027] A cable support for a power transmission line, comprising a mounting plate 1, wherein the side of the mounting plate 1 is provided with power transmission line fixing structures at equal distances; the power transmission line fixing structures can assist the displacement of the cable body 7 when the cable body 7 is installed in a subway tunnel for dragging and arranging the cables, thereby preventing the cable body 7 and the supporting structure from being worn and affecting the service life of the cable body 7;

[0028] The transmission line fixing structure includes a fixing plate 2 which is vertically fixedly connected to the mounting plate 1, and the fixing plate 2 cooperates with the mounting plate 1 to support the cable body 7 as a whole. Three groups of support plates 3 are fixed at equal distances on the upper end surface of the fixing plate 2. The design of the three groups of support plates 3 structure can install more cable bodies 7 in a limited installation environment. A transmission line drum 4 is rotatably connected between adjacent support plates 3. A transmission line trough 8 of an annular structure is provided in the middle of the outer surface of the transmission line drum 4. Mainly through the rolling of the transmission line drum 4, when the cable body 7 located in the transmission line trough 8 is dragged, the transmission line drum 4 can rotate with the cable body 7, thereby avoiding the wear of the cable body 7; the cable body 7 is movably connected in the transmission line trough 8, and the upper side of the cable body 7 is movably connected to a clamping plate 5 at a position between the two support plates 3, and a limited position clamping structure is provided between the lower end surfaces of the clamping plate 5 and the transmission line drum 4;

[0029] The clamping structure includes a clamping block 10 fixedly connected to the clamping plate 5, and the lower end surface of the clamping block 10 is evenly distributed with fixed limiting blocks 11, and the two ends of the outer surface of the transmission line drum 4 are provided with limiting grooves 9 corresponding to the limiting blocks 11. When the cable body 7 is completed, the user installs the clamping block 10 between the two support plates 3, and the limiting blocks 11 are inserted into the limiting grooves 9 provided on the outside of the two ends of the transmission line drum 4. Similar to the meshing and fixing method of gears, the transmission line drum 4 is limited to avoid the rolling and slipping phenomenon with the transmission line drum 4 when the cable body 7 is shaken by the environment.

[0030] The front and rear ends of the clamping plate 5 are fixedly connected to the corresponding positions of the cable body 7 with a wrapping elastic sheet 6, and the wrapping elastic sheet 6 is composed of an elastic metal structure. The lower end surface of the wrapping elastic sheet 6 is fixedly connected with a non-slip silicone gasket 15. The transmission line drum 4 is made of ceramic material, and the purpose is to provide insulation protection between the cable bodies 7. The wrapping elastic sheet 6 is designed to increase the contact area of ​​the clamping plate 5 with the cable body 7, increase the friction resistance to the cable body 7, and ensure that the cable body 7 is firmly clamped. The design of the non-slip silicone gasket 15 can also avoid wear caused by hard contact between the cable body 7 and the wrapping elastic sheet 6.

[0031] Rotating shafts 14 are fixed to both ends of the transmission line drum 4 , and the transmission line drum 4 is rotatably connected to the support plate 3 via the rotating shafts 14 .

The height of the clamping plate 5 between the two support plates 3 is adjusted mainly by slidingly connecting the sliders 12 and the sliding grooves 13, so that the lower end surface of the clamping plate 5 cooperates with the wrapped elastic sheet 6 to fit tightly with the cable body 7 in the lower transmission trough 8. After the adjustment is completed, the user inserts the bolt into the threaded hole for threaded connection, and the rear end of the bolt abuts against the slider 12 to prevent the slider 12 from moving.
