Embodiment 1

[0078] Embodiment 1: This embodiment 1 is the embodiment of the software computing technique among the present invention.

[0079] see figure 1 , establish the coordinate system as shown in the figure. For the convenience of calculation, take the position of the guide height (assuming the guide height is 5300mm) as the abscissa, and assume that the abscissa distance from the coordinate origin to node 0 is 0, that is, node 0 is ( 0,y 0 ), assuming that the height of the catenary cable at node 0 measured on site is 6.908 meters, and the guide height is 5300mm (refer to the guide height of a passenger train), then the structure height here is 6.909m-5.3m=1.608m, so the node The coordinate of 0 is (0,1.608).

[0080] Taking the suspension string length at nodes 1, 2, 3, and 4 as an example, the calculation of the suspension string length is as follows:

[0081] Step 1: Assume that the span of the two nodes 0 and 9 is 49 meters according to the on-site measurement. According to ...

Abstract

A full-compensation elastic chain hanging construction method for high-speed rail contact network, which comprises a construction preparing process, a construction measuring process, a software calculating process, a precasting process for sling and dropper, a mounting adjusting process for sling and dropper, and an ending process; each process is equipped with uniform and high-quality construction standards, and is assisted by modern construction meanses for satisfying with technical requirements for construction of high-speed rail contact network of 350 km / h; the software calculating process especially can obtain more accurate pre-stowage data of dropper length via a brand new calculating method finding form based on sling net, and then improve elastic chain hanging construction accuracy for high-speed rail contact net of 350 km / h. So the construction method does not only benefit for improving accuracy of sling and droppser calculation, and the construction method but also has high-quality construction standards and modern construction meanses, and is capable of improving quality and speed of construction of high-speed rail contact net of 350 km / h.

Description

technical field [0001] The invention relates to a construction method for catenary suspension, in particular to a construction method for full-compensation elastic chain-type suspension of high-speed railway catenary, and is particularly suitable for installation and construction of full-compensation elastic-chain suspension for 350km / h high-speed railway catenary. Background technique [0002] 350km / h Catenary Elastic Chain Suspension Description: The contact line in this suspension is suspended and controlled by two integral elastic suspension strings arranged equidistantly from the positioning point within 11 meters from both ends of the positioning point. The elastic suspension strings are installed On the elastic sling of the catenary (the elastic hanging string on the elastic sling between the two positioning points, and other intermediate hanging strings are integral non-adjustable hanging strings), the catenary guide height is controlled by the hanging string, and the...
