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...

Abstract

The invention discloses a small curve radius flexible positioning structure of a catenary of a tramcar, which comprises a fulcrum. A support is disposed on the fulcrum, and an insulator is connected with the support by an adjusting bolt, and is connected with a contact wire via a steel strand, a positioning ring, a positioning tube and a wire clamp sequentially. The invention further discloses a construction method of the flexible positioning structure. By the aid of the method and the structural design, conflicts of the fulcrum of the catenary of the urban tramcar and road traffic are solved, simultaneously, requirements on urban landscape are met, and performances of the catenary are improved. The small curve radius flexible positioning structure is simple and reliable, accordingly, construction and maintenance costs are lowered, and the small curve radius flexible positioning structure has wide applicability.

Description

technical field [0001] The invention relates to the field of traffic technology, in particular to a small curve radius soft positioning structure of a tram catenary and a construction method of the small curve radius soft positioning structure. Background technique [0002] With the continuous deepening of urban construction, modern trams have obvious advantages as a means of transportation and have good development prospects. Sharing the right of way between trams and road traffic will become one of the important forms of urban intensive urban space development. [0003] The tram catenary is erected above the road, and its pillars will inevitably have an impact on road traffic. At the turning intersection of trams, the turning radius is small, the suspension points are many, and the pillars are dense, which is a prominent contradiction with road traffic. Under the conditions of normal road traffic, no pillars can be set up on the road; while under the normal working condi...
