Small-radius I-shaped switch rail telescopic regulator for on-site transformation and transformation construction method thereof

Abstract

The invention discloses an on-site transformed small-radius I-shaped switch rail telescopic regulator and a transformation construction method thereof. The telescopic regulator comprises a continuous large iron plate, a cover plate structure, a base plate assembly and a fastener system, wherein the continuous large iron plate extending along a track bed is anchored to the portion, at the bottom of a rail bearing groove, of the track bed; a plurality of base plate assemblies and cover plate structures are arranged along the continuous large iron plate, the base plate assemblies are fixed to the continuous large iron plate through fastener systems, the cover plate structures are fixed to the continuous large iron plate and cover the area, from a rail head of a stock rail or a switch rail to the edge of a rail bearing groove, of the continuous large iron plate, and guide rail supports, fixed rail supports, the stock rail and the switch rail are fixed to the base plate assemblies; each base plate assembly comprises a sliding table base plate and a height adjusting pad, the height adjusting pads are arranged between the sliding table base plates and the continuous large iron plates, and thickness of the height adjusting pads in all the base plate assemblies is set according to the set height of the vertical curve at the corresponding position. According to the telescopic regulator, the site construction speed is high, and requirements on the vertical curve, lead curve radius, safety and the like of the telescopic regulator can be met.

Description

technical field [0001] The invention belongs to the field of railway engineering, and in particular relates to an on-site reformed small-radius I-shaped point rail telescopic regulator and a reforming construction method thereof. Background technique [0002] Due to the different materials between the bridge and the ground, it is generally necessary to install telescopic regulators at the joints when setting up the track. In this way, it is necessary to renovate the track lines that have not been equipped with telescopic regulators in the past, and add telescopic regulators at the joints , Improve the reliability of the track line operation in the past. Some bridges originally used a mixed pavement structure that can be used by trains and cars. Generally, grooved rails or I-shaped rails are buried in the set-up rail bearing grooves. The interior is filled with sand, and the top is made of concrete as needed. The pavement is supported, while other parts are paved with strong...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a small-radius I-shaped tip rail telescopic adjuster for on-site transformation, which is used to solve the problem of insufficient space for the original rail bearing groove in the prior art when adding a telescopic adjuster to rails on mixed roads. The available skylight period of the process is limited, so the technical problem that affects the feasibility of the transformation under the premise of ensuring safety and reliability
