Method for overhauling supporting and positioning devices in high speed railways

Abstract

The invention discloses a method for overhauling supporting and positioning devices in high speed railways. When skewing of cantilevers and positioners exceeds the rule and skewing of the cantileversis adjusted, screws of force bearing cable supporting wire clamps are directly loosened, the cantilevers are pushed by hands to the specified positions, and when skewing of the positioners exceeds therule, contact wires are pushed by the hands; when the stress of the positioners is large and thus the positioners cannot be unloaded by manpower, positioning wire clamps are loosened to adjust the positioners to the specified positions; when the slopes of the positioners do not meet the requirement, under the premise that the heights of contact nets are ensured, the lengths of droppers are adjusted; when the error range is exceeded due to adjustment of the lengths of the droppers, the mounting heights of positioning pipes or lower fixing ropes are increased or decreased till the positioning slopes meet the requirement, and the stagger value is adjusted again; and the wire clamps at the positioners incline, the positioning wire clamps are loosened, and wires are twisted right through a face righting device. According to the method for overhauling the supporting and positioning devices in the high speed railways, by setting the reasonable overhauling technique, the overhauling quality meets the requirement, the supporting and positioning devices meet the design requirement, and train operation is safer.

Description

technical field [0001] The invention relates to a method, in particular to a method for overhauling a support and positioning device in a high-speed railway. Background technique [0002] High-speed railway is referred to as "high-speed railway", which refers to the transformation of the original line (linearization, gauge standardization) to make the highest operating speed not less than 200 kilometers per hour, or to build a new "high-speed new line" to make the operating speed reach 200 kilometers per hour. A rail system with at least 250 kilometers per hour. For high-speed railways, in addition to reaching a certain speed standard in train operation, the vehicles, rails, and operations all need to be upgraded. When the support and positioning device in the existing high-speed railway is overhauled, the overhaul is not in place, and there is no strict overhaul process, resulting in omissions, making it not up to standard, and prone to safety accidents.

Problems solved by technology

[0003] The purpose of the present invention is to overcome the above-mentioned existing problems that when the support and positioning device in the high-speed railway are overhauled, the overhaul is not in place, there is no strict overhaul process, and omissions are caused, so that the standard cannot be reached, and safety accidents are prone to occur. A method for overhauling a support and positioning device in a high-speed railway. By setting a reasonable overhaul process, the method makes the overhaul quality meet the requirements, the support and positioning device meet the design requirements, and the train runs more safely. When the support and positioning device in the railway is overhauled, the overhaul is not in place, and there is no strict overhaul process, resulting in omissions, making it not up to standard, and prone to safety accidents
