Abstract

The invention relates to a line temporary overhead device and method for ballastless track disease treatment, belonging to the technical field of railway ballastless track disease elimination. The temporary overhead device comprises a steel cushion beam, a support, a limiting device and a fastener. The longitudinal beam of the steel cushion beam is welded with a steel plate and has a box section.The upper flange of the longitudinal beam is provided with a plurality of fasteners for locking the rail and the longitudinal beam. The two ends of the longitudinal beam are also supported on the railconcrete support layer through bearings respectively. The connection between the longitudinal beam and the support is provided with a finite position device A. The joint of the longitudinal beam, thefirst small cross beam and the last small cross beam is respectively provided with a finite position device B. The line temporary overhead device for ballastless track disease treatment improves theintegrity and construction convenience of the overhead structure, and enables the overhead device to realize the adjustment of the vertical and lateral positions, and a plurality of overhead devices can be connected with each other, and the overhead line can be formed by adopting the combination of a plurality of devices for the lines with a long disease treatment range.

Description

technical field

[0001] The invention relates to a temporary overhead device and a method for controlling ballastless track diseases, and belongs to the technical field of railway ballastless track disease elimination. Background technique

[0002] With the development of high-speed railways, ballastless tracks are widely used in high-speed railway lines due to their high smoothness, good rigidity uniformity, and long-lasting track geometry. Operation practice in recent years has shown that the overall state of the ballastless track structure is normal, but under the long-term train operating load and the external environment, the mortar layer bond gradually fails, the reinforced concrete support layer is damaged, and the cracks on the track slab arch occasionally occur , resulting in poor track geometry, which brings great safety hazards to the normal operation of the line. Once the track structure is damaged, it should be repaired and rectified in time. When the repair ope...
