High-speed railway turnout large-size component replacing and laying device and method

Abstract

The invention discloses a high-speed railway turnout large-size component replacing and laying device and method. The high-speed railway turnout large-size component replacing and laying device comprises a traction rail car, a first flatcar set, a second flatcar set, a third flatcar set, a power generation rail car, an engine arm, an engine arm bogie, a movable supporting column, a fixed supporting column, a crane trolley and an electrical control system. The movable supporting column is configured at the front end of the engine arm. The movable supporting column and the fixed supporting column are configured with the engine arm through a transverse motion mechanism. The replacing and laying device is used for replacing and laying a point rail or a frog; when the point rail is replaced and laid, the point rail is lifted through the crane trolley, the first flatcar set and the second flatcar set are controlled to exiting an operation region, the crane trolley lifts the point rail to a designated region; then, an old rail is lifted to the outer side of a circuit; then, after the point rail is adjusted to an installation position, and the old rail is lifted and transported. The artificial construction method which is originally adopted is changed, labor intensity of construction workers is lowered, meanwhile, the working quality and safety are improved, and the construction operation time is shortened.

Description

technical field [0001] The invention relates to equipment and a method for changing paving of large parts of high-speed railway turnouts. Background technique [0002] A high-speed railway turnout is a line connection device that allows rolling stock to transfer from one track to another, and is usually laid in large numbers at stations and marshalling yards. The turnout is composed of large parts such as point rails, frogs, and basic rails. [0003] High-speed railway turnouts are large-numbered speed-up turnouts, which are characterized by long size, easy deformation, and difficulty in transportation and hoisting. Traditional transportation and lifting equipment cannot meet the requirements of rapid transportation, hoisting and replacement of large parts. [0004] The replacement of large parts of high-speed railway turnouts has not yet achieved mechanized construction operations in China, and the construction method of manual replacement is mainly used. This constructio...

AI Technical Summary

Problems solved by technology

The requirements for relaying of high-speed large-number turnouts are getting higher and higher. Traditional manual laying and replacement may easily cause permanent deformation of large parts and accessories of turnouts or laying accuracy that cannot meet the requirements, which takes more time and delays the next day's train operation.

There is no equipment specially used for the replacement of large parts of high-speed railway turnouts in China, and it is imminent to develop equipment for the replacement of large parts of high-speed railway turnouts and its construction methods
