Problems solved by technology

At present, domestic constant-tension and low-tension stringing equipment cannot be used for normal operation on tram lines due to the small radius of ballast bed and curve, and the operation of tension stringing devices is complicated, and there are many links to control tension, which requires a huge investment of personnel. The wire is completed, and the efficiency of the wire is slow

Embodiment

[0041]This embodiment discloses the construction method of small tension wire setting-out of modern tram catenary. The tram catenary is composed of single or multiple contact wires arranged in parallel, and the contact wires are arranged on the ground at equal distances. The pillars are supported, and the setting-out project is to carry out the construction work of an anchor section. The pillar at the starting position of the anchor section is the anchor pillar, and the end point is the anchor pillar. Tension compensation devices are installed on the two pillars of anchor lifting and anchor dropping. The specific construction steps are as follows:

[0042] 1. Construction preparation

[0043] (1) First, the equipment personnel enter the site, install and erect the basic equipment, start debugging and inspecting the equipment, and ensure that the quality and quantity of the pay-off machinery, tools and materials meet the operation requirements. The equipment includes catenary w...

Abstract

The invention discloses a modern tramcar contact network small tension setting-out method. The method comprises the steps of S1, firstly based on design drawings making work preparation, S2, arranging a tension compensation device A at an anchor section beginning end, S3, using a contact network erection car to weigh anchor at an anchor pillar, and connecting the contact line and the tension compensation device A, S4, in weighing anchor, based on a start tension calculation value, presetting a control tension to set out, S5, during setting-out, making the contact network erection car move slowly to increase the control tension in an average speed, S6, moving the contact network erection car to an anchor falling pillar for anchorage, S7, arranging a tension compensation device B on the anchor falling pillar, S8, connecting the contact network line anchor falling end and the tension compensation device B and setting the tension, and S9, testing the line erection work quality and completing the work. The modern tramcar contact network small tension setting-out method guarantees the tramcar contact network erection quality and duration, and therefore the method is not only suitable for the special lines of tramcars, but also can satisfy the setting-out erection tension of contact network lines.

Description

technical field [0001] The invention relates to a construction method for small-tension wire setting-out of modern tram catenary. Background technique [0002] Modern trams are light rail transit vehicles driven by electricity and running on rails. Tram is a kind of public transportation, also known as streetcar, or tram for short, which is a kind of light rail (train driven by electric power, also known as tram). But usually they all walk on the street, and the train has only a single section, up to five sections. Since trams are driven by electricity, the vehicles do not emit exhaust gas, so they are a pollution-free and environmentally friendly means of transportation. In some factory areas, living areas and scenic spots, trams are often set up for short-distance transportation, and in the construction process of trams, the catenary for its upper part to provide electric energy needs to be strictly constructed and erected. The catenary is a high-voltage transmission li...
