Embodiment Construction
[0023] Such as image 3 , Figure 4 As shown, a small curve radius soft positioning structure of a tram catenary, including a pillar 1 of the catenary. The pillar 1 is set up on the road diversion island or both sides of the road outside the curve of the contact line 9, so that the pillar 1 does not affect the ground road traffic. The pillar 1 is a welded steel pillar, and in this embodiment, the distance from the centerline of the road is greater than 20 meters.
[0024] There is a support 2 on the pillar 1, and the support 2 is fixed at the set position of the pillar 1. The angle and length of the steel strand 51 and the position of the support 2 on the pillar 1 are determined through mechanical calculations, and installed according to the calculated position Support 2.
[0025] One side of the insulator 4 is connected with the support 2 through the adjusting bolt 3 . The other side of the insulator 4 is connected to the contact wire 9 through the steel strand 51, the po...
