A centerline adjustment assembly for double-block tie construction

Abstract

The utility model belongs to ballastless track construction technical field, concretely relates to a kind of middle line adjusting assembly for double-block sleeper construction, including transverse adjustment mechanism and supporting leg mounting seat;The rail fixed frame of transverse adjustment mechanism is connected with multiple double-block sleepers;And with sample rail vertical fixed connection;Move supporting leg place and supporting leg mounting seat sliding connection;Transverse lead screw is set in transverse supporting leg, and transverse lead screw sleeve is connected with the transverse lead screw sleeve of the fixed body of mounting seat;Transverse drive motor is connected with transverse lead screw transmission;Two transverse lead screws are synchronously linked by transmission rod, to control the telescopic movement of transverse supporting leg along square through-hole, realize middle line adjustment.In the scheme, concrete will not be mixed due to open gap, and the subsequent use of equipment and middle line adjustment difficulty will be affected;Transverse supporting leg only contacts with supporting leg mounting seat and is provided with needle roller, to reduce friction resistance;Transverse supporting leg and rail fixed frame are detachable, to save assembly time and improve engineering progress.
