Quick fine adjustment device for ballastless track plate

Abstract

The invention relates to a quick fine adjustment device for a ballastless track plate. The device comprises a main framework and a plurality of leveling bearing platforms, wherein the leveling bearingplatforms are used to be installed on two sides of the installation position of a track plate to be adjusted, and the top surfaces of the leveling bearing platforms are provided with a V-shaped alignment groove; two sides of the main framework are independently provided with vertical adjustment mechanisms, each vertical adjustment mechanism is provided with a wedge-shaped bottom end adaptive to the V-shaped alignment groove; the wedge-shaped bottom end is erected in the V-shaped alignment groove to enable the main framework to be erected above the installation position of the track plate to be adjusted; the main framework comprises a track plate adjustment mechanism used for moving the track plate to be adjusted; and the track plate adjustment mechanism is used for cooperating with the vertical adjustment mechanism to adjust the four-corner elevation and the center line position of the track plate to be adjusted. The device has the advantages that the leveling bearing platforms and the vertical adjustment mechanisms are cooperated, and the longitudinal position of the track plate to be adjusted is quickly positioned.

Description

Technical field [0001] The invention relates to the field of rail transportation, in particular to a fast and fine adjustment device for ballastless track slabs. Background technique [0002] Ballastless track is the main track structure of my country's high-speed railway. After the high-speed railway ballastless track was put into operation, with the development of time, some potential structural problems gradually developed into structural damages and diseases, such as track slab damage, under the combined action of train load, external environment, and deformation of the underlying structure. Damage, mortar layer separation, etc. The damage to the structure of the ballastless track has become the focus of the maintenance and repair of the ballastless track due to its difficult maintenance, high cost, and high safety risk. [0003] At present, in several ballastless tracks of high-speed railways operated earlier, cracks, bulging, falling blocks, and even map-like cracks have be...
