Method of adjusting the height of a fixed rail carriageway, in which the sleepers supporting the rails are embedded in a carriageway panel resting on a substrate includes the steps of separating the carriageway panel from the substrate at the common contact face, forming filling apertures extending from the upper face to the lower face of the carriageway panel, lifting the carriageway panel to a fixed target height, incorporating a flowable casting material through the filling apertures in order to fill the space between the carriageway panel and the substrate, wherein separation is effected by pressure impacts.
摘要:
The present invention relates to a stabilizer support system and a method for stabilizing or supporting heavy equipment in general. The system may comprise a support structure such as a conventional A-frame that is configured to support a crane or heavy equipment. The system and method are designed to provide an adapter to support the structure by distributing weight and load onto, for example, a rail or similar transportation system while still allowing movement of the structure along the rails or other transportation system.

A track bed rehabilitating machine comprises a machine frame supported on a track by undercarriages for movement along the track in an operating direction. The machine frame comprises a first machine frame part, a second machine frame part and a third machine frame part. A first coupling links the second machine frame part to the first machine frame part, a second coupling links the third machine frame part to the second machine frame part, and one of the undercarriages is arranged adjacent the first coupling. Two crawler tractors are spaced from each other in a direction extending transversely to the machine frame and connected to the second machine frame part, and drives connect the crawler tractors to the second machine frame part for vertically adjusting the crawler tractors.

A foreign matter removing device Y1 for use in a turnout X1 is provided with a base rail 100 and a tongue rail 200. The foreign matter removing device Y1 is provided with an inlet member 4 including an inlet channel 44, the inlet member 4 extending in the width direction of the base rail 100 in a region lower than a bottom surface B1 of the base rail 100; and a connecting portion 22 including a communication channel 22c for communicating a nozzle portion 21 which injects a foreign matter removable medium to between the base rail 100 and the tongue rail 200, and the inlet channel 44. The connecting portion 22 is connected to one end portion 41 of the inlet member 4 in the region lower than the bottom surface B1 of the base rail 100. The other end portion 42 of the inlet member 4 disposed on the outside of the bottom surface B1 of the base rail 100 in top plan view is configured such that the operator can hold the one end portion 41 in a state that the one end portion 41 does not fall off from the connecting portion 22.
摘要:
A system for performing track maintenance operations is described. The system includes a lead vehicle for identifying sections of rail that have been pre-marked for track maintenance operations. The lead vehicle further includes a control system for receiving and transmitting coordinates of the pre-marked track sections. The system further includes at least one drone vehicle for receiving the coordinates from the control system and the drone vehicle has at least one workhead for performing track maintenance operations on the pre-marked track sections.

This invention includes a method for estimating the shape of a section of railroad track from so-called chord offsets measured along it without prior assumptions about the locations and orientations of arcs and tangents that together could define a shape to which the track might be made to conform. This invention also includes a method for finding a configuration of tangents, arcs, and spirals that are as close as practical to a set of existing points along a section of track and that can define a desired shape for calculating instructions to a track lining machine.
摘要:
A method for aligning measured track data collected from a railroad track to correct geographic location information for geometric parameters in the measured track data includes steps for (a) obtaining track geography data for use as reference data in data alignment; (b) reconstructing the track geography data to simulate in form and in coverage of length the measured track data to be aligned, (c) comparing the reconstructed reference data to the measured track data to identify a relative misalignment value between the data types; and (d) using the value identified through comparison to correct the geographic location information contained in the measured track data.
