Embodiment Construction

[0034] The track maintenance machine 1 comprises a frame 2, at least two axles 3 supported on the frame 2, a machine drive 4 and a tamping device 5 for consolidating the track bed. The axles 3 are arranged at a distance from one another along the horizontal x-direction on the track maintenance machine 1 . The x direction together with the vertical z direction and the horizontal y direction form a machine fixed coordinate system. Rail-guided wheels 6 are rotatably mounted on the axle 3 . The machine drive 4 is designed for rotationally actuating a wheel 6 of at least one axle 3 .

[0035] The tamping device 5 has a unit holder 7 and a tamping unit 8 mounted relative to the unit holder 7 in the z direction. The tamping unit 8 comprises four tamping picks 8a and a consolidation drive 8b. The tamping picks 8a are respectively mounted on a tamping pick holder 8c, and mounted to rotate about a holder axis 8d via the tamping pick holder 8c. The tamping pick holder 8c can be drive...

Abstract

In a method for operating a tamping assembly (8) of a track construction machine (1), a track construction machine (1) having a tamping assembly (8), a drive force sensor system and an acceleration sensor system is first provided on a track bed (21). The tamping assembly (8) is displaced relative to the track bed (21). A drive force (FA), which acts on the tamping assembly (8) and is necessary forthe displacement, and an acceleration (az) acting on the tamping assembly (8) are determined. A ballast force (Fs) effective between the tamping assembly (8) and the track bed (21) is defined using the drive force (FA) and the acceleration (az) and is evaluated.

Description

technical field [0001] The invention relates to a method of operating a tamping unit of a track maintenance machine, a tamping device for consolidating a track bed and a track maintenance machine. Background technique [0002] Rail-guided track maintenance machines are used to maintain ballast beds. For the consolidation of the ballast bed, track maintenance machines of this type have a tamping device comprising a displaceable tamping unit. In operation, the tamping unit is displaced back and forth between a reset position, in which the tamping unit is not engaged with the track bed, and an engaged position, in which the tamping unit is engaged with the track bed. In this way, high static and dynamic loads act on the tamping unit. In order to maintain the functionality of the highly stressed components of the tamping unit, time-consuming and costly inspection and maintenance operations are required on a regular basis. Contents of the invention [0003] It is an object o...
