crts type I ballastless track retest rail transport vehicle

Abstract

The invention discloses a rail transport vehicle for repetition measurement of a CRTS I type ballastless track, and belongs to rail transport devices. The rail transport vehicle for repetition measurement of the CRTS I-shaped ballastless track structurally comprises a front side transport vehicle body and a rear side transport vehicle body, and the front side transport vehicle body and the rear side transport vehicle body each comprise a chain hoist, wheels, a track grabbing hook, a support frame and a connecting rope; the number of the wheels is four, and every two wheels are symmetrically arranged on left and right sides of a rail; an axle is arranged between every two wheels which are arranged in a bilaterally symmetrical mode; bearings are arranged between the axles and the wheels; the support frames are arranged on the upper portions of the two axles correspondingly; each chain hoist is arranged on top of the corresponding support frame; each track grabbing hook is arranged on the lower portion of the corresponding chain hoist, and each track grabbing hook is connected with the corresponding chain hoist through the corresponding connecting rope. According to the rail transport vehicle for repetition measurement of the CRTS I type ballastless track, the rail can be lifted and separated from a rail bearing platform through the chain hoists and the track grabbing devices, two transport vehicles can operate simultaneously, and the rail can be lifted simultaneously, thus the rail can be pushed forwards manually, and the rail transport vehicle for repetition measurement of the CRTS I ballastless track has the advantages of being capable of saving manpower greatly, reducing cost, improving work efficiency and the like.

Description

technical field [0001] The invention relates to a rail transport device, in particular to a CRTS I type ballastless track retesting rail transport vehicle. Background technique [0002] With the intensive launch of high-speed railways in my country, ballastless track is the top priority of high-speed railways, and its construction accuracy directly affects the adjustment of fasteners for the later fine-tuning of the track and the benefits of the project. Baolan Passenger Special Ballastless Track adopts CRTS I type double-block ballastless track. The on-site construction adopts the rail layout method, which has fast construction speed and high efficiency. After the completion of the construction, the measurement and retesting shall be carried out in accordance with the principle of 100% rechecking, which requires that the moving speed of the retesting rail must be accelerated to ensure the speed of data collection, and the measurement method of the front field shall be adju...

AI Technical Summary

Problems solved by technology

It not only consumes a lot of labor, but also has low efficiency and high security risks

15 or 6 people are required to work at the same time each time, and it takes more than three hours to move and complete a working surface, which consumes a lot of manpower and physical strength, and cannot guarantee the speed synchronization between retesting and ballastless track construction in the front field

And it is easy to damage the completed project, causing bruises and bruises to the rail bearing platform
