DEVICE FOR INSTALLATION OF CONTINUOUS WELDED TRACK RAILS UNLOADED INSIDE TRACK IN DESIGN TEMPERATURE RANGE OF FIXATION AT REPLACEMENT OF INVENTORY RAILS BY THEM Russian patent published in 2024 - IPC E01B29/17 

FIELD: transportation.

SUBSTANCE: invention relates to means of laying long-length continuous welded track rails unloaded inside the track, instead of inventory rails, with setting them to design temperature range of fixation. Device consists of two bogies moving along the track, connected to each other and to the traction unit. Each of the trolleys contains support and anti-edging rollers. One of the bogies is intended for shifting inventory rails inside the track. Other bogie is designed to lift the strings unloaded inside the track and slide them onto the under-rail base. Bogie (3), designed for lifting strings unloaded inside the track, and sliding them onto the under-rail base, contains lifting crossbar (9), on which support rollers (7) are mounted and which is installed in vertical guides (14) with possibility of lifting and lowering by means of hydraulic cylinders (15) located in pairs in the longitudinal direction relative to the path, wherein said bogie (3) frame accommodates system coupled with temperature transducer interacting with rail to control hydraulic cylinders.

EFFECT: increasing the stability of the position of the support rollers of the bogie, designed for lifting rails unloaded inside the track, and sliding them onto the under-rail base.
