摘要： The present disclosure generally relates to a road rail stoneblower vehicle for carrying out rail maintenance operations near fixed structures such as bridges and overpasses. The road rail stoneblower includes a hi-rail chassis having a first set of wheels configured to engage a road surface and a second set of wheels configured to engage surfaces of substantially parallel rails of a railroad track. The road rail stoneblower further includes a plurality of workheads that are capable of dispensing ballast stones into a bed of ballast underlying the railroad track to adjust the height of the rails. The road rail stoneblower further includes a leveling system detachedly coupled to the hi-rail chassis that is configured to transmit a detectable signal that defines a reference plane with which the rails are to be aligned. Related methods of operation of the road rail stoneblower vehicle and associated maintenance of ballast beds underlying railroad tracks are also described.

摘要： A railway rail induction-welding device is provided which includes a device support and a railway rail alignment means for aligning opposing railway rails in three mutually perpendicular directions, the railway rail alignment means being supported by the device support. The railway rail alignment means includes first and second railway-rail clamping elements to horizontally and longitudinally align the opposing railway rails when gripped by the first and second railway-rail clamping elements, with at least one of the first and second railway-rail clamping elements being movably supported by the device support, and a vertical lifting means for moving each railway-rail clamping element vertically to align the opposing railway rails. A railway rail clamping and lifting module, a vehicle a railway rail induction-welding device, and a method of inductively welding opposing railway rails together are also provided.

摘要： A device for in-situ, dynamic repair of a railroad can include two connected machines. A first one of machines can be a track lifting unit that can clamp the rails of the railroad and lift the track in its entirety out of its track bed. The first machine also can plow ballast away from and/or toward the rails, and level the track bed for the rails before they are lowered. In addition, the track lifting unit can remove selected railroad ties. The second machine can include a power unit that can provide hydraulic, pneumatic and electrical power to both machines. The power unit also can provide track stabilization by settling ballast and can free debris from the railroad while it is raised.

摘要： By supporting a space generated by a settlement of the track bed gravel or asphalt roadbed underneath a concrete rail tie with cylindrical rods, and installing the present invention, one each separately, on the left and right sides of the concrete rail tie, recovery from settlements is automatic, and the response to differential settlements of the left and right rails of the track due to the train load can be easily facilitated, and by installing pressure reducing valves on the upper part of the concrete rail ties, pressure can be reduced while maintaining the track system as is without having to dismantle the concrete rail ties, and accordingly the usability of the concrete rail ties can be improved.

摘要： The invention refers to a machine and a method used to level, align and stabilise the track and compact the ballast bed, producing controlled lifting, so that the load used in the settlement of the rail in its theoretical position falls within the established range, working in an uninterrupted manner. The machine is constituted by two bogies with traction capacity, and front, back and centre control cabins and a rear and frontal measuring tensioner trolleys. The machine has an additional lifting unit whose relative movement with the rest of the machine in controlled by total longitudinal cylinder. The alignment cylinders generate a transversal movement to cause track alignment. Behind this unit according to the direction of work a stabilising unit is situated which consists of two stabilising trolleys. The ground-penetrating radar is situated at the machine front.

摘要： A track mounted machine is capable of inserting a previously positioned tie plate between a rail and underlying cross tie of a railway. The machine preferably is also capable of lifting the rail from the tie prior to tie plate insertion and/or, is capable of operating on both rails of a railway simultaneously. The preferred embodiment includes two tie plate inserter assemblies mounted on a common workhead. Each tie plate inserter assembly includes a pusher that can be moved, under control of an operator stationed on the machine, vertically and longitudinally on the rails so as to be aligned with a field end of the tie plate. The pusher can then be actuated to push the tie plate laterally under the rail.

摘要： In a method of tracing a track geometry immediately ahead of a ballast pick-up device of a cleaning machine in a working direction, a first and a second measuring chord are guided on the track by a respective front and rear end point. A versine measured by a first versine sensor of the first measuring chord is stored, in connection with a distance measurement, for registering the rear end point of the first measuring chord as a desired position with respect to a local track point. After the rear end point of the second measuring chord has reached the local track point, the rear end point is displaced until a measurement value corresponding to the stored versine is reached by a second versine sensor, and thus the desired position has been attained.

摘要： A method for correcting the track geometry of a track, includes measuring an initial track position of the track following lifting of the track and tamping under the track, and so computing a final desired track position as to eliminate long-wave alignment errors of the track geometry. Subsequently, corrective values are determined commensurate with a difference between the final desired track position and the initial track position, and the track is stabilized by lowering the track in a controlled manner into the final desired position and controlling in response to the corrective values the static load and/or transverse vibration acting on the track, thereby eliminating during track stabilization in particular long-wave geometrical track errors.
