[0002] The main function of transmission line towers is to support transmission lines so that they can cross various terrains such as rivers, mountains, and forests, ensuring the stable operation of transmission lines. Compared with laying transmission lines on the ground, using overhead transmission lines with towers can reduce the land area and reduce the occupation of land resources.

[0003] When installing cables on towers, brackets are needed to support them. The brackets can reduce friction and wear between the cables and other objects, extend the service life of the cables, and keep the cables neatly arranged, making subsequent maintenance and inspection easier. However, the current support structures of the brackets are fixed, and there is a lack of buffering when supporting the cables, making the cable surface at the support position susceptible to pulling and impact, affecting the service life of the cables. Utility Model Content

[0004] The purpose of the utility model is to provide a transmission line tower cable bracket, which solves the problem proposed in the background technology that the supporting structure of the current bracket is fixed, lacks buffering when supporting the cable, and makes the cable surface at the supporting position susceptible to pulling and impact.

[0006] In this technical solution, several sliding frames are slid in according to the number of cables, and the spacing between each sliding frame can be freely set to adapt to cable support in different situations. It is very practical. The cable is located between two clamps, and the clamps are attached to the cables under the action of shock absorbers. The balls and guide rollers facilitate the forward and backward sliding of the cables, and the shock absorbers and clamps can provide left and right positioning and buffering when the cables swing left and right, thereby reducing the pulling and impact of the cables on the supporting parts, and improving the protection effect and support capacity of the cables.

[0007] Preferably, the front and rear inner wall surfaces of the bracket body are both provided with cushions.

[0008] Preferably, a rubber pad is fixedly connected to the center of the bottom of the top plate, and grooves are provided at the four corners of the top of the top plate.

[0021] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, they are further elaborated below in conjunction with specific implementation methods.

[0022] A transmission line tower cable support, see Figures 1 to 3 , including a bracket body 1, a sliding frame 2, a top plate 6 and a connecting screw 9. A notch 103 is opened in the center of the top of the bracket body 1. The sliding frame 2 is located on the inner side of the bracket body 1 and is slidably connected on the inner horizontal line of the bracket body 1. Two guide rollers 3 are rotatably connected between the left and right inner walls of the sliding frame 2. Two bottom grooves 4 are opened on the inner bottom surface of the sliding frame 2 below the guide rollers 3. Two plywood 5 are provided on the inner side of the sliding frame 2, and the bottom protrusion of the plywood 5 is located on the inner side of the bottom groove 4 and is slidably connected laterally along the bottom groove 4. A number of balls 501 are evenly inlaid and rotatably connected on the surface of the opposite side of the plywood 5. A shock absorber 8 is fixedly connected between the plywood 5 and the inner wall of the sliding frame 2. The shock absorber 8 is always in a compressed state. Therefore, when the cable pushes the plywood 5 on one side to move, the plywood 5 on the other side can still fit the cable under the push of the shock absorber 8, thereby providing clamping and buffering for the cable, improving the supporting capacity and protection effect.

[0023] Specifically, such as Figure 1 As shown, the front and rear inner wall surfaces of the bracket body 1 are both provided with soft pads 104. The soft pads 104 can provide a certain degree of protection and cushioning to the front and rear of the sliding frame 2, reduce wear, and provide protection during the sliding process.

[0024] It is worth noting that if Figure 2 As shown, a rubber pad 603 is fixedly connected to the center of the bottom of the top plate 6, and grooves 601 are provided at the four corners of the top of the top plate 6. The inner side of the groove 601 is threadedly connected with a fixing bolt 602. The bottom end of the fixing bolt 602 passes through the top plate 6 and is threadedly connected to the main body of the sliding frame 2. The rubber pad 603 can prevent the cable from directly hitting the top plate 6. After being tightened, the fixing bolt 602 will be completely immersed in the groove 601, without affecting the normal sliding of the sliding frame 2 and the top plate 6 in the bracket body 1.

[0025] It is worth noting that if Figure 1 and Figure 2 As shown, an adjustment groove 101 is provided at the top of the bracket body 1, and a number of positioning grooves 102 are evenly provided at the top of the bracket body 1 along the direction of the adjustment groove 101. The top center of the top of the top plate 6 is threadedly connected with a limiting bolt 7. The adjustment groove 101 can facilitate the limiting bolt 7 to align with the positioning groove 102. After the limiting bolt 7 is fully screwed into the positioning groove 102, the entire top plate 6 and the sliding frame 2 can be fixed in the bracket body 1, maintaining stability.

[0026] It is worth noting that if Figure 3 As shown, the connecting screw 9 passes through one of the clamping plates 5 and is rotatably connected to the other clamping plate 5 through a bearing. A nut 10 is threadedly sleeved on the surface of the connecting screw 9. After rotating, the connecting screw 9 can adjust the distance between the two clamping plates 5, so that when the cable swings left and right, the two clamping plates 5 can move synchronously to maintain the clamping of the cable, and the nut 10 can be tightened to fix the connecting screw 9.

[0027] It is worth noting that if Figure 1 As shown, the left and right widths of the sliding frame 2 are consistent with the width of the notch 103, and the front and rear surfaces of the sliding frame 2 are respectively in contact with the front and rear inner walls of the bracket body 1. Therefore, the sliding frame 2 will not swing freely when sliding in the bracket body 1, ensuring the stability of the sliding and facilitating the subsequent fixing of the limit bolts 7.

[0028] It is worth noting that if Figure 2 and Figure 3 As shown, the guide roller 3 passes through the surface of the clamping plate 5, and there is a certain gap between the guide roller 3 and the clamping plate 5, so the clamping plate 5 will not affect the rotation of the guide roller 3 when it moves left and right normally.

[0029] In actual use, the top plate 6 is opened so that the cable can be pulled between the two clamping plates 5. Then the top plate 6 is installed, and the sliding frame 2 is slid into the bracket body 1 through the notch 103. A number of sliding frames 2 are slid in according to the number of cables, and the spacing between each sliding frame 2 can be freely set to adapt to cable support in different situations. It is very practical. At the same time, the clamping plates 5, the balls 501, the guide rollers 3 and the shock absorbers 8 can support and buffer the cables. The cables are located between the two clamping plates 5. The clamping plates 5 are attached to the cables under the action of the shock absorbers 8. The balls 501 and the guide rollers 3 facilitate the forward and backward sliding of the cables, while the shock absorbers 8 and the clamping plates 5 can provide left and right positioning and buffering when the cables swing left and right, thereby reducing the pulling and impact of the cables in the supporting parts, improving the protection effect and supporting capacity of the cables, and improving practicality.
