[0032] Referring to the attached Figure 2 , attached Figure 3 and attached Figure 4 , an embodiment provided by the present invention: an installation device for a catenary wire positioning bracket, including a column 1. A second support column 4 is arranged on the left side of the column 1. The outer wall of the second support column 4 is fixedly connected with a base 6. A positioning pipe 7 is arranged on the left side of the base 6. The right side of the positioning pipe 7 is fixedly connected with a fixing block 8. A plurality of connecting plates 9 are fixedly connected to the left side of the base 6. Third through holes 10 are opened at the upper and lower ends of the fixing block 8 and the connecting plates 9. A rotating rod 11 is arranged inside the third through holes 10. Threaded holes 12 are opened at the upper and lower ends of the outer wall of the rotating rod 11. Nuts 13 are threadedly connected to the outer walls of the two threaded holes 12. A rotating assembly is arranged on the outer wall of the positioning pipe 7. An installation seat 18 is arranged at the bottom of the positioning pipe 7. A positioning wire clamp 19 is arranged on the left side of the installation seat 18. A telescopic mechanism 2 is arranged on the outer wall of the positioning wire clamp 19. The telescopic mechanism 2 is used to adjust the length of the positioning wire clamp 19; a positioning rod 14 is fixedly connected to the right side of the fixing block 8. A sliding groove 15 is opened on the outer wall of the base 6. The outer wall of the positioning rod 14 is slidably connected inside the sliding groove 15, providing preliminary precise positioning for the installation of the positioning pipe 7, ensuring the accurate installation position, reducing subsequent adjustment work, and improving the installation accuracy; the rotating assembly includes an installation block 20. The inner side of the installation block 20 is fixedly connected to the outer wall of the positioning pipe 7. A servo motor 16 is fixedly connected to the top of the installation block 20. The output end of the servo motor 16 penetrates through the top of the installation block 20 and is fixedly connected with a rotating shaft 17. The bottom of the rotating shaft 17 is fixedly connected to the top of the installation seat 18, which can achieve precise adjustment of the angle of the positioning wire clamp 19, making the positioning wire clamp 19 better cooperate with the catenary wire; a first support column 3 is fixedly connected to the left side of the column 1. A connecting rod 5 is fixedly connected to the adjacent sides of the first support column 3 and the second support column 4; insulating pads 23 are fixedly connected to the outer walls of the first support column 3 and the second support column 4; fixing columns 21 are fixedly connected to the outer walls of the first support column 3, the positioning pipe 7, and the positioning wire clamp 19.

The model of the servo motor 16 is MHMJ022G1U.

[0034] Refer to the appendix Figure 5 Specifically, the telescopic mechanism 2 includes an adjusting column 202. The inner side of the adjusting column 202 is slidably connected to the outer wall of the positioning wire clamp 19. A groove 203 is opened on the inner side of the adjusting column 202, and a plurality of first through holes 201 are opened on the outer wall of the positioning wire clamp 19. A plurality of second through holes 204 are opened on the outer wall of the adjusting column 202. The plurality of first through holes 201 and the second through holes 204 are all connected by bolts 205. Nuts 206 are threadedly connected to the outer walls of the plurality of bolts 205, ensuring that the positioning wire clamp 19 will not accidentally slide or loosen during the working process. A distance measuring instrument 207 is fixedly connected to the right side of the adjusting column 202, which can measure the distance between the positioning wire clamp 19 and surrounding objects in real time.

[0035] Specifically, the adjusting column 202 can slide on the outer wall of the positioning wire clamp 19, enabling the length of the positioning wire clamp to be flexibly adjusted according to the actual installation situation, which can meet the installation requirements of different catenary conductors and adapt to different line conditions and construction scenarios. The plurality of first through holes 201 and the second through holes 204 are connected by bolts 205 and nuts 206, and can be firmly fixed at different length positions, ensuring that the positioning wire clamp 19 will not accidentally slide or loosen during the working process, guaranteeing the stability and reliability of the catenary conductor positioning. The distance between the positioning wire clamp 19 and surrounding objects can be measured in real time by the distance measuring instrument 207 on the right side of the adjusting column 202. Especially during the installation process, key parameters such as the limit gap can be accurately detected, which helps the construction personnel to make more precise installation adjustments and improve the installation quality.

[0036] Refer to the appendix Figure 1, on the right sides of the first support column 3 and the second support column 4, there are fixedly connected fixing plates 24. The two fixing plates 24 and the column 1 are connected by a plurality of second bolts 25, which can effectively disperse and bear the forces from all directions, improving the stability of the entire catenary wire positioning bracket installation device;

[0037] Specifically, the first support column 3, the second support column 4 and the column 1 are connected together through the fixing plate 24 and the second bolts 25 to form a more stable overall structure, ensuring the positioning accuracy of the catenary wire.

[0038] Working principle: When the positioning pipe 7 needs to be installed on the second support column 4, first align the positioning rod 14 on the fixing block 8 on the right side of the positioning pipe 7 with the sliding groove 15 opened on the outer wall of the base 6 for preliminary positioning. Then insert the rotating rod 11 into the third through holes 10 opened at the upper and lower ends of the fixing block 8 and the connecting plate 9, and rotate the fixing block 8 to drive the positioning pipe 7 to rotate. When the angle of the positioning pipe 7 is adjusted, tighten the first nut 13. Through the pressure generated by tightening the first nut 13, the fixing block 8 is closely attached to the connecting plate 9, thus realizing the firm fixation of the positioning pipe 7 and the base 6. The output end of the servo motor 16 penetrates through the top of the mounting block 20 and is connected to the rotating shaft 17. When the servo motor 16 is started, the output end drives the rotating shaft 17 to rotate. The bottom of the rotating shaft 17 is fixedly connected to the top of the mounting seat 18. Therefore, the rotation of the rotating shaft 17 will drive the mounting seat 18 to rotate. And a positioning wire clamp 19 is arranged on the left side of the mounting seat 18, so that the angle of the positioning wire clamp 19 can be adjusted by driving the servo motor 16;

[0039] And the inner side of the adjusting column 202 is slidably connected to the outer wall of the positioning wire clamp 19, which enables the adjusting column 202 to slide relative to the positioning wire clamp 19. A plurality of first through holes 201 are opened on the outer wall of the positioning wire clamp 19, and a plurality of second through holes 204 are opened on the outer wall of the adjusting column 202. When the adjusting column 202 is adjusted to the appropriate position, align the plurality of first through holes 201 and the corresponding second through holes 204, and then pass the first bolts 205 through the aligned first through holes 201 and second through holes 204, and thread the second nuts 206 on the outer walls of the first bolts 205. After tightening the second nuts 206, the first bolts 205 fix the positioning wire clamp 19 and the adjusting column 202 together, thus realizing the fixation of the positioning wire clamp 19 at a specific length. At the same time, use the distance measuring instrument 207 to detect the limiting gap.
