Problems solved by technology

During the construction process, due to the long length and heavy weight of the 25-meter-long track system, and the influence of the steel mesh below the track system, it is very inconvenient to adjust the geometric shape of the track system; at the same time, because there is no The geometric shape and position adjustment device with convenient operation and high precision also causes defects such as low construction efficiency and unsatisfactory track geometry and position

Abstract

The invention discloses a rail ditch fine adjustment device. The device comprises two groups of rail ditch fine adjustment units used for adjusting two groups of rail ditch rail systems arranged in parallel respectively, each rail ditch fine adjustment unit comprises a sleeper, a lateral adjustment unit, a height adjustment unit and a support unit; multiple sleepers are arranged at the bottoms of the rail ditch rail systems at intervals and used for supporting the rail ditch rail systems; each lateral adjustment unit is arranged on the upper surface of each sleeper and comprises two lateral adjustment sub units located on the two sides of the corresponding rail ditch rail system, and the lateral adjustment sub units make contact with the side surfaces of the rail ditch rail systems and used for adjusting lateral track geometries of the rail ditch rail systems; multiple height adjustment units are arranged in the lower spaces of the rail ditch rail systems and used for adjusting the scale heights of the rail ditch rail systems; multiple support units are arranged in the lower spaces of the rail ditch rail systems and used for fixing the scale heights of the rail ditch rail systems after adjusting the scale heights of the rail ditch rail systems.

Description

technical field [0001] The invention belongs to the technical field of rail transit, and more specifically relates to a novel fine adjustment device for a rail bearing groove. Background technique [0002] With the development of track technology, the embedded ballastless track system without fasteners and continuous support is widely used because of its good force bearing, environmental protection and shock absorption. Embedded ballastless track system mainly includes ballast bed slab type, rail support channel type and steel channel type. The rail-supporting trough track system is widely used because of its relatively light weight and easy factory prefabrication. [0003] The current commonly used rail bearing groove track system consists of 4 rail bearing grooves and 25 meters of steel rails connected together by elastic bodies. During construction, it is necessary to adjust the track system of the bearing groove to the required geometrical position, and then re-cast th...
