Abstract

The invention relates to a method for correcting vertical position defects of a track after a lifting-tamping process, with a stabilizing process carried out by means of a dynamic track stabilizer in which a stabilizing unit acts on the track at a forward-moving working point in a working direction, with track position data of the untreated track being recorded before the lifting-tamping process, and with track position data of the tamped track being recorded after the lifting-tamping process at a measuring point located in front of the stabilizing unit in the working direction. In this case, additional track position data of the stabilized track are recorded at an post-measuring point located behind the stabilizing unit in the working direction, with the dynamic track stabilizer being actuated during the stabilizing process as a function of track position data of the untreated and the tamped track at the working point and of track position data of the stabilized track at the post-measuring point. The additional post-measurement of the track position after the stabilizing process enables precise control of the dynamic track stabilizer.

Abstract

An arrangement for optically capturing a railroad track includes a carrier device, a camera, and two light sources. The arrangement is mountable on a carrier vehicle that is movable on rails. The alignment of the two light sources and thus the central axes of the emitted light radiation or waves enclose an acute angle with a longitudinal axis of the rail. The light sources are coupled with the camera via control signal lines. The triggering or activation of the light sources is effected via the control signal lines by a predefined control signal. This achieves detailed, sharp image contours that allow high-precision image evaluation and object recognition at the highest possible working speed.

Abstract

A method for determining a target geometry of a track for correcting the geometry of the track. An actual geometry of the track is detected first on a track section by a measuring system and the target geometry is calculated on the basis of the actual track geometry afterwards by way of a computing unit. Actual position points of the track are detected along the track section by a position detection system, with at least one actual position point being given to the computing unit as a point of restraint, and with the target geometry being calculated by the computing unit such that the target geometry is adapted to the actual geometry as a sequence of geometric track alignment design elements and is placed through the preset point of restraint. The method achieves a significant increase in quality compared to the known compensation method using pre-measurement.

Abstract

A method for controlling/regulating a rotatory drive of a working unit of a track maintenance machine includes using a sensor to record a measurement parameter with an approximately periodic history function derived from a rotation of the drive. A frequency or period duration of the history function is determined with an evaluation device, and the frequency or period duration is compared with a target parameter for stipulating a control signal. A number of time-discrete measurement values is formed for the measurement parameter and an auto-correlation of these measurement values is carried out by a calculation unit for determining the frequency or the period duration. As compared to a conventional method with zero stage recording, a precise recording of frequency changes is therefore also possible between two zero stages. A device for carrying out the method is also provided.

Abstract

The invention relates to a method and a machine comprising a tamping assembly for tamping sleepers (4), mounted on a ballast bed (2), of a track (3) by means of a tamping assembly (7) which is intended for simultaneously tamping a plurality of sleepers positioned directly one behind the other and comprises a plurality of tamping units (14) that are arranged directly one behind the other in a working direction (26), are height-adjustable independently of one another, and are each intended for tamping a particular sleeper (4), wherein: in a tamping cycle, firstly a first group of tamping units (14) that are not arranged directly one behind the other is lowered into the ballast bed (2), fed laterally and raised again; a second group of tamping units (14) that are not arranged directly one behind the other is preferably lowered into the ballast bed, fed laterally and raised again; and, before the start of the next tamping cycle, the tamping assembly (7) is moved further in the working direction (26). This prevents two tamping tools (18) from operating simultaneously on the same ballast grains in close proximity.

Abstract

A method for stabilizing a track having sleepers supported on a track ballast and rails secured to the sleepers, includes using a stabilizing unit which is connected to a machine frame that can be moved on the rails and has a vibration exciter and rollers that can roll on the rails. The vibration exciter generates in particular horizontal vibrations which run transversely to the track longitudinal direction. The course of a force exerted onto the track by the stabilizing unit is recorded over a vibration path during a vibration cycle by sensors. At least one parameter is derived from the course by an evaluation device and is used to evaluate the stabilizing procedure and/or the quality of the track ballast. A device for implementing the method is also provided.

Abstract

A method for compacting a ballast bed, on which railroad ties and track rails secured thereto are supported, uses a work assembly which is arranged on a track construction machine that can be moved on the track. During a compaction process, a signal is detected and a characteristic variable is derived therefrom by an analysis device in order to evaluate the quality of the ballast bed. The work assembly contains an electric drive, by which the compaction process is at least partly carried out. At least one operating variable of the electric drive is supplied to the analysis device, and a ballast bed characteristic variable is derived from the operating variable by the analysis device.

Abstract

A tamping unit for tamping sleepers of a track includes a tool carrier supported in a lowerable manner on an assembly frame, on which two pivot levers with tamping tools are mounted so as to be squeezable toward one another and, while being actuatable with a vibration, are rotatable about a respective rotation axis. A sensor for recording a pivot angle of a pivoting motion about the related rotation axis is associated with at least one pivot lever. The sensor has a multipart configuration with a first sensor part fastened to the tool carrier and a second sensor part fastened to the pivot lever. In this manner, sensitive sensor components in the first sensor part are subjected to lessened stress since the tool carrier merely performs a lowering or lifting motion during a tamping operation. A method for operating the tamping unit is also provided.
