Definitions
- the invention relates to a sweeping device for processing a track formed from rails and sleepers with a brush shaft consisting of several shaft sections, which is designed as a hollow shaft, having elastic and radially protruding sweeping elements, via at least one adjustable vertical drive on a movable on rails Vehicle attachable.
- ballast bedding secures the track position against track warpage.
- ballast is removed using appropriate ballast plows.
- flank plows for example, the bed flank is profiled, i.e. the correct slope angle is created.
- the flank plows pull the ballast into the upper area of the bedding towards the bedding crown.
- crown plow picks up the ballast and distributes it in the track area depending on the position of its guide plates.
- a sweeping system removes any remaining gravel grains from the sleeper surfaces.
- Sweeping devices are often equipped with a cross conveyor belt, which then either unloads excess ballast from the side or transports it to a storage silo via another conveyor belt.
- the sweeping systems are of particular importance, here one speaks of a so-called deep sweep.
- the gravel is in the middle of the Threshold compartments, that is the area between two neighboring thresholds, swept deeper than the threshold surface.
- AT 395875 B discloses a track construction machine for processing the ballast bedding of a track.
- the ballast sweeping device arranged in the sleeper area consists of three height-adjustable and rotatable by drives independently of one another, arranged one behind the other in the cross machine direction
- the total of three sweeping rollers only extend over the entire threshold area and the axes of rotation of the two outer sweeping rollers can be adjusted independently of one another at an angle to the rotation axis of the central sweeping roller or to the track plane.
- EP 2775035 B1 shows a sweeping device with improved application possibilities and an adjustment possibility, which is implemented by a control shaft guided inside the hollow shaft with an eccentric bearing.
- the invention is based on the object of providing a device of the type mentioned above, greater flexibility in adapting to different threshold shapes, as well as an increase in the sweeping performance and thus economy of the machine with an accompanying improvement in the quality of the sweeping pattern compared to the prior art . According to the invention, these objects are achieved by a device according to claim 1.
- Dependent claims relate to advantageous embodiments of the invention.
- the invention provides that at least one axis of rotation of a shaft section can be adjusted via a control shaft with control elements acting on the outside of the shaft section.
- control elements are joined to the rotatably mounted control shaft and are designed in a sword-like shape.
- One embodiment of the invention provides that the control shaft is acted upon in rotation via a mechanical linkage and at least one gear.
- a gear mechanism that adjusts the control shaft about its axis of rotation is acted upon by a translational actuator via a corresponding articulation mechanism.
- the transmission converts the translational control movement into a rotational degree of freedom that drives the control shaft.
- the actuator is designed as a double-acting hydraulic cylinder, the supply takes place via the existing on-board hydraulic system. This enables easy control and regulation.
- An internally attached position / displacement measuring system can also be used to determine the position of the piston. It is particularly advantageous if the gear is designed as a worm gear.
- the individual shaft sections of the brush shaft are movably connected via cardan joints.
- One embodiment provides that the brush shaft is driven by means of at least one laterally arranged chain drive.
- the brush shaft consists of five shaft sections.
- the five-part hollow shaft design allows optimal adaptability to almost all common sleeper shapes, especially concrete sleepers with partially sloping surfaces. This design also covers the middle of the sleeper in its entirety, leaving no undesirable accumulations of gravel. This area is of particular importance in high-speed traffic, where the gravel in the middle of the sleeper compartments must be swept deeper than the sleeper surface in the case of a so-called deep sweep.
- a useful further development of the invention is that two control elements act on the middle part of the shaft sections, one control element each acting on the bearing point on the left and right of it.
- the sweeping elements which are arranged elastically and radially on the brush shaft, are made of solid material or internally hollow, tubular products.
- the design is characterized by a larger diameter of the hollow shaft and consequently a larger shaft circumference. This means that more sweeping elements can be accommodated compared to previous machines. Thus, a higher sweeping performance is achieved with an even, clean sweeping pattern.

- FIG. 2 view of a multi-part brush shaft with sweeping elements
- Fig. 3 sectional view of a multi-part brush shaft with sweeping elements
- Fig. 4 isometry of a multi-part brush shaft with sweeping elements
- Fig. 5 isometry of a multi-part brush shaft without sweeping elements
- Fig. 6 side view a sweeping device with a brush box
- FIG. 7 isometric drawing of a sweeping device with a brush box
- Fig. 1 shows a simplified vehicle 1 for processing a track 5 formed from rails 3 and sleepers 4, which through Rail trolleys 2 can be moved on track 5.
- This comprises a driving and work cabin 6, a drive unit 7, a sweeping device 8 and plows 9 for manipulating the ballast 26.
- the sweeping device 8 is attached to the vehicle via an adjustable height drive 23.
- the brush shaft 10 shows a view of a multi-part brush shaft 10 over a sleeper 4 with rails 3.
- the brush shaft 10 consists of five shaft sections 11 (see also FIG. 5), which are designed as hollow shafts.
- the sweeping elements 12 are made of elastic material, protruding radially therefrom, and these can be individually exchanged.
- the shaft sections 11 are joined to one another by universal joints 13.
- FIG. 3 The embodiment explained above for FIG. 2 is shown in FIG. 3 with the aid of a sectional view through the axis of rotation 24.
- the middle part of the shaft sections 11 is designed to be height-adjustable by two control elements 17; the control elements 17 engage on the left and right in the area of the cardan joints 13.
- the arrangement is symmetrical, the two adjacent parts of the central shaft section are therefore inclined in terms of amount by the same angle.
- FIG. 4 shows an isometric view of a multi-part brush shaft 10 with sweeping elements 12; the sweeping device is attached to the vehicle 1 via an adjustable height drive 23.
- the brush shaft is acted upon by means of two hydraulic drives 14, each arranged laterally, via chain drives 15.
- the control shaft 16 with the control elements 17 is mounted on the support frame 21 of the device 8.
- a gear is installed on the control shaft 16, designed as a double, self-locking worm gear 18.
- the control is carried out by a translatory hydraulic cylinder 20 which is connected to the worm gears 18 via a mechanical linkage 19.
- FIG. 5 shows an isometric view of a multi-part brush shaft 10, but without sweeping elements 12, in order to clearly show the entire structure of the brush shaft 10 with the individual shaft sections 11 and in particular the points of engagement of the control elements 17.
- the shaft sections 11 are connected by cardan joints 13.
- In the The neutral, undeflected position of the control elements 17 is the axis of rotation 24 of the shaft sections 11 parallel to the axis of rotation 25 of the control shaft 16.
- the control shaft 16 is designed shaft-in-shaft, that is, only the two central control elements 17, which are immediately left and right of the middle shaft section 11 attack adjacent, are rotatable. All other control elements 17 are rigidly joined to the outer profile of the control shaft 16.
- FIG. 6 shows a side view of the sweeping device 8 in the brush box 22.
- the support frame 21 is directly connected to the brush box 22.
- FIG. 7 shows an isometric drawing of the sweeping device 8 in the brush box 22.
