Embodiment Construction

[0024] A kind of metro rigid catenary trackless construction method, such as figure 1 , 2 shown, including the following steps:

[0025] Step 1. Calculation of catenary suspension point 7

[0026] A. Determine the starting point. In the section with a turnout, select a position 4m away from the center of the turnout as the starting point, that is, the mileage of the starting point = the distance of the turnout - 4m; in the section without a turnout, select the anchor section joint The first point is the starting point, and the mileage of the starting point is the terminal mileage + span value obtained by direct measurement on the CAD drawing; B. Calculate the 7 mileage of each suspension point, and calculate the mileage of the next point through the span; that is The mileage of the next point = the mileage of the starting point + the span; if the anchor section is at the fork, use the Excel accumulation formula, that is, the mileage of the next suspension point 7 is equal to...

Abstract

The invention belongs to the technical field of construction of subway vehicle power supply. In order to solve technical problems of subway rigid catenary system construction of large operation interference, long construction period and low working efficiency, the invention provides a trackless construction method for a subway rigid catenary system. The trackless construction method for the subway rigid catenary system comprises the following steps of step 1, calculating a catenary system suspension point; step 2, measuring and positioning the rigid catenary system suspension point; step 3, suspending, assembling and calculating the rigid catenary system; and step 4, suspending, assembling, mounting and rechecking the rigid catenary system. The invention is advantaged in that the positioning point position and the clearance height are determined before track laying, the construction efficiency is increased, the construction cost is saved, a problem that construction period delay is caused because the construction of the catenary system depends on a steel rail is solved, the gap in the domestic trackless construction technique of the urban subway rigid catenary system is filled and good economic benefit and social benefit are obtained.

Description

technical field [0001] The invention belongs to the technical field of subway vehicle power supply construction, and in particular relates to a trackless construction method for a subway rigid catenary. Background technique [0002] The subway catenary is the main component of electrified urban rail transit, the power source of rail transit vehicles, and is responsible for providing power to rail locomotives. The construction of rigid catenary for urban rail transit, according to the conventional construction process, can only be carried out on the premise that the track has been locked and no longer changed, because the detection parameters of the rigid catenary (lead height, pull Output value) and acceptance criteria are all based on the track as a reference, which is the relative relationship between the rigid catenary and the track. At present, the traditional subway rigid catenary construction adopts the method of track construction. The main disadvantages of track con...
