Technical Field

[0001] The invention relates to the technical field of pole towers, and in particular to a transmission line pole tower structure. Background Art

[0002] Transmission line towers are pole-shaped or tower-shaped structures that support overhead transmission line conductors and overhead ground wires and keep a certain distance between them and the ground. Its main function is to support and overhead conductors, lightning arresters and other accessories, to ensure that the conductors and conductors, conductors and towers, conductors and lightning arresters, and conductors maintain a specified safe distance from the ground or crossover objects, to prevent safety problems such as short circuits caused by too close distances;

[0003] When assembling traditional transmission line towers, the brackets are too long, so when fixing the cables on the outermost side of the brackets, it is necessary to reach a higher position or a farther distance to fix the cables. This not only increases the complexity of the operation, but also prolongs the installation time and reduces work efficiency. At the same time, due to the remote location, installers may need to use additional tools or equipment to assist the operation, which increases the difficulty and cost of the operation and increases the risk of high-altitude operations. Summary of the invention

[0035] Reference Figure 2 , Figure 3 and Figure 4As shown, when the device is used, firstly combine the two groups of clamps 23 to the top of the rod body 1, place the reinforcing sheet 22 on both sides of the clamp 23, and pass the bolts through the holes on both sides thereof to preliminarily fix the reinforcing sheet 22 and the clamp 23, then insert the insert 25 into the limiting groove 24, and then tighten the bolts so that the clamp 23 firmly squeezes and fixes the rod body 1, flip the reinforcing sheet 22 upward, connect the top of the reinforcing sheet 22 to the connection point of the top of the bracket 3 respectively, and fix them by bolts. After the position of the bracket 3 is preliminarily determined, the bracket 3 and the rod body 1 are squeezed and limited again by the clamp 7, so that the bracket 3 is fixed for the second time to enhance its stability;

[0036] A slide 51 is installed on the top of the base 5, and a slide groove 56 is provided at the bottom of the slide 51. A convex block 55 is provided on the top of the base 5, and a sliding structure is formed between the convex block 55 and the slide groove 56. A movable groove 57 is provided on the opposite side of the slide 51 and the base 5. A movable block 54 is provided inside the movable groove 57. A stud 52 penetrates inside the movable block 54, and a nut 53 is installed at one end of the stud 52.

[0037] Reference Figure 7 , Figure 8 and Fig. 9 As shown, when the device is used, the base 5 is first installed with the top of the slide 32 by bolts, and the initial position of the slide 32 is located on the inner side of the bracket 3. The nut 53 is rotated, and the threaded cooperation between the nut 53 and the stud 52 makes the slide 51 constantly approach the base 5 and intersect, and the cooperation between the slide groove 56 and the protrusion 55 makes the slide 51 slide upward along the curvature of the base 5, and the arc design between the movable block 54 and the movable groove 57 solves the angle change caused by the adjustment of the stud 52, so that the slide 51 can move up and down along the base 5 to achieve the height adjustment of the cable to a height suitable for assembly;

[0038] The top of the lower snap ring 6 is hinged with an upper snap ring 61, one side of the lower snap ring 6 is hinged with a fixing column 63, and a fixing block 62 is installed on the top of the fixing column 63, the fixing block 62 and the fixing column 63 are threadedly connected, one side of the upper snap ring 61 is provided with a fixing groove 64, both ends of the inside of the fixing groove 64 are installed with connecting seats 643, and the inside of the connecting seat 643 is hinged with a limiting piece 642, and a spring 641 is installed between the limiting piece 642 and the inner wall of the fixing groove 64;

[0039] Reference Figure 7 , Fig.10 and Fig.12As shown, when the device is used, the upper clamping ring 61 is turned outward, and after the cable is placed inside the lower clamping ring 6, the upper clamping ring 61 is turned back to its original position, and the fixing block 62 is pulled to drive the fixing column 63 to turn to the inside of the fixing groove 64. When the fixing column 63 slides into the fixing groove 64, the limiting piece 642 is squeezed, so that the limiting piece 642 approaches the inner wall of the fixing groove 64, and the fixing column 63 slides into the innermost side of the fixing groove 64. After the limiting piece 642 loses its squeezing, it is connected to the seat under the action of the tension of the spring 641. 643 is the center rebound reset, and the opposite ends of the limiting piece 642 are squeezed, so that the outer side of the fixing groove 64 is closed, and the fixing column 63 is initially limited. Then the fixing block 62 is rotated. Through the threaded cooperation between the fixing block 62 and the fixing column 63, the fixing block 62 continuously moves downward while rotating and fits tightly with the top of the fixing groove 64. Because the outer diameter of the bottom of the fixing block 62 is larger than the inner diameter of the fixing groove 64, the fixing column 63 cannot be turned over in the locked state, so that the fixing column 63 is limited for the second time, and the stability is enhanced;

[0041] Reference Figure 4 , Figure 5 , Figure 6 and Fig.11 As shown, when the device is in use, after the cable is fixed, the rotating torsion block 34 drives the screw rod 31 to rotate, and through the threaded cooperation between the screw rod 31 and the slide 32, the two groups of slides 32 are driven to move to the outermost side at the same time during rotation, driving the cables above them to move to the outermost side of the bracket 3, reducing the difficulty of operation due to long distances, and after the cable displacement is completed, the limit cylinder 351 is pulled close to the torsion block 34 so that the inner teeth 352 and the outer teeth 353 are engaged, and the torsion block 34 and the screw rod 31 on one side thereof are locked to avoid the phenomenon that the screw rod 31 rotates to drive the slide 32 to deviate, and the cooperation between the slider 355 and the connecting groove 354 prevents the limit cylinder 351 from being separated from the connecting cylinder 35 when pulling. After the outermost cable of the bracket 3 is fixed, the base 5 is assembled with the inner side of the bracket 3 by bolts, and then assembled with the cable.
