Online grinding construction method for railway steel rail mounting groove

Abstract

The invention discloses an online grinding construction method for a railway steel rail mounting groove, and aims to quickly realize descending adjustment of an upward arching deformation section of aballastless track and effectively solve the deformation adjustment problems of upward arching and the like of the ballastless track. The method comprises the following steps: determining the length of a line adjustment section according to disease conditions and positions; measuring the rail temperature; enabling a steel rail mounting groove milling and grinding vehicle to reaching the site; starting a first cycle operation; inputting vertical and transverse milling amounts of all sleeper positions of the line adjusting section into a steel rail mounting groove milling and grinding vehicle control system; completing milling operation and ash suction operation at a time according to the milling amount set by the control system; according to a milling amount instruction set by the control system, carrying out automatical operation until the milling operation of all sleeper positions within the coverage range of the guide shaft of the steel rail mounting groove milling and grinding vehicle is completed; enabling the milling and grinding vehicle to walk to a second circulating operation station to carry out operation to the milling and grinding operation end point; completing the milling and grinding operation completely, and driving the steel rail mounting groove milling and grinding vehicle out of the station; replacing a fastener sleeve; and enabling the steel rail mounting groove milling and grinding vehicle to leave the site through rail transportation, and recovering the line.

Description

technical field [0001] The invention belongs to the technical field of railway engineering track adjustment, and in particular relates to an online grinding construction method of railway rail installation grooves. Background technique [0002] Railway engineering is a spatial linear project reflected by the laying position of rails. At the same time, it relies on rails to guide wheels and transmit loads. The accuracy of rail laying directly affects driving safety and comfort. Due to its stable structure and less maintenance, ballastless track is widely used in the construction of high-speed railways. Furthermore, due to the obvious advantages of the shoulder sleeper in resisting the lateral force of the rail, the shoulder sleeper is more suitable for the construction of high-speed railways, such as the SK-2 type sleeper used in my country's high-speed railway, and the high-speed rail sleeper matched with the SK-2 type sleeper. The railway fasteners are WJ-8 type fasteners. ...

AI Technical Summary

Problems solved by technology

[0003] The invention provides an on-line grinding construction method for railway rail installation grooves, which can quickly realize the adjustment of the descending path of the upper arch deformation section of the ballastless track, reduce the risk of operation safety, and do not demolish or destroy the ballast bed and the foundation under the line in a large area, and damage the structure The damage is small, and at the same time, multiple operations can be performed on the diseased section according to the deformation development, effectively solving the problem of deformation adjustment such as ballastless track arching
