Problems solved by technology

Here, the tamping unit is heavily loaded, which can result in damage to the tamping unit, in particular breaking of the tamping picks
In the event of a damage to the tamping unit, the ballast bed is only insufficiently compacted and this can lead to excessive loading of the operable components of the tamping unit
Time-consuming and cost-intensive control and maintenance work is therefore carried out regularly in order to detect damage to the tamping unit as early as possible

Embodiment Construction

[0052] The track construction machine 1 has a machine frame 2 , at least two shafts 3 mounted on the machine frame 2 , a machine drive 4 and a tamping device 5 for compacting the track bed. The shafts 3 are arranged at a distance from one another in the horizontal x-direction on the track construction machine 1 . The x-direction and the vertical z-direction and the horizontal y-direction together form a coordinate system that is fixed relative to the machine. Wheels 6 , which can be guided by guide rails, are rotatably mounted on the shaft 3 . The machine drive 2 is designed to drive a wheel 6 of at least one of the shafts 3 in rotation.

[0053] The tamping device 5 has a unit carrier 7 , a tamping unit 8 mounted on the unit carrier 7 , a drive unit 9 , a sensor 10 and an evaluation unit 11 . A linear guide 12 is arranged between the unit carrier 7 and the tamping unit 8 . The tamping unit 8 is displaceably movable in the z-direction relative to the unit carrier 7 via line...

Abstract

In a method for operating a tamping assembly (8) of a track construction machine (1), the track construction machine (1) together with the tamping assembly (8) is first provided on a track bed (19). At least one part (18, 24) of the tamping assembly (8) is accelerated, at least one measurement variable which correlates to the acceleration is detected by a sensor, and the state of damage of the tamping assembly (8) is ascertained by an analysis unit using the at least one measurement variable.

Description

technical field [0001] The invention relates to a method for operating a tamping unit or a bed tamping unit of a track construction machine, and also to a tamping device for compacting a track bed and a track construction machine. Background technique [0002] Track construction machines guided by guide rails are used to maintain the ballast bed. For compacting the track bed, such a track construction machine has a vertically movable tamping unit with a unit frame and at least two tamping picks that are movable relative to the unit frame. The tamping unit repeatedly moves vertically between the reset position and the engagement position during operation. In the reset position, the tamping unit does not engage with the ballast bed; in the engagement position, the tamping unit engages with the ballast bed . In addition, at least two tamping picks are periodically moved relative to the assembly frame. In this case, the tamping unit is heavily loaded, which can result in dama...
