Description

Cleaning device for a track system and one with such

Cleaning device equipped rail vehicle

The invention relates to a cleaning device for cleaning a track system intended for rail vehicles with a track and track sills having track bed of pourable or pourable impurities, wherein the cleaning device is designed as a can be arranged on a rail vehicle mobile unit. Furthermore, the invention relates to a rail vehicle equipped with such a cleaning device.

For cleaning a track superstructure, a device is already known from DE 20 2009 009 649 U1 for cleaning track superstructures and tunnel walls. such

Systems are often used for surface cleaning on commuter trains as an integral part of entertainment. This concerns especially the

Increasing pollution of railway facilities by waste, especially cigarette remains, waste paper, packaging and the like, but also by brake sand, dust and metallic abrasion of the rails. To ensure the highest possible working speed and suction in the tunnel area, only air is used as a cleaning medium and produced by the inclination of the air nozzles in the cleaning area immense vortex, which ensures the functionally necessary overpressure curtain and promotes the solution of the pollutants from the surface to be cleaned. In an advantageous embodiment of the solution according to the invention, the suction power is varied within the blowing and suction system, in particular by the inclined position of the air nozzles, the loosened or dissolved dirt particles are sucked into the absorbent body.

Although the above device for cleaning a track superstructure of contaminants, in particular packaging waste, gives excellent results, this principle is included

CONFIRMATION COPY Natural phenomena that spill the entire track system over a large area, and the associated movement of large quantities of bulk material only conditionally usable.

On the other hand, snow masses or snowdrifts, which also severely impair or paralyze public rail traffic beyond a critical mass, can hardly be removed by means of extraction techniques. For such cases, however, snow plows have already proven, with which the surfaces of the rails can be exposed with relatively little effort. Unlike sand or gravel

the snow remaining in the track bed between the rails does not fundamentally affect the wheel flange extending there. Rather, the snow can be easily compressed or displaced there.

The situation is different with contamination by sand, gravel, dust and other pourable or pourable substances, such as those found in industrial plants, such as gravel pits, or in sandy areas, such as deserts, beach or dune landscapes. For example, sand dreads dreaded in the desert can quickly accumulate large amounts of sand that completely cover the track bed and rails.

Even with such obstacles attempts have already been made to eliminate the sand by means of a snowplow modeled slider, so as to clear the rail surface in a conventional manner. However, it has been shown that the sand in the space between the rails must be removed because otherwise the flange must penetrate into the incompressible sand and displace it. This creates considerable problems because the necessary lateral displacement succeeds only at low speeds and also leads to considerable resistance, which in extreme cases can lead to a lifting of the wheel and thus a derailment.

Furthermore, the wear of the tires increases because at least small amounts of sand are transported to the rail surface by the displacement, which then develop a considerable abrasive effect between the rail surface and the wheel tire. This also causes damage to the rail and the wheel tire.

From DE 82 36 650 U1 a device for extracting the ballast of a track with resting on a ballast bed, formed of sleepers and rails track grille is also known. This has a suction tube with a rectangular or round suction nozzle, which is connected to a rubber apron, the side of an inlet opening or has a suction opening open in the direction of work. The over the track sill top in the longitudinal direction of the device moving suction nozzle should be through this side suction opening in or next to the track grate dust or

Pick up gravel stones. The suction nozzle also has an adjustment across the track and in the vertical direction.

DE 35 43 040 C2 relates to a track-traveling device for extracting the ballast from a track grid formed below a track sleepers and rails

located ballast bed whose machine frame is provided with a connected via a suction pipe to a compressor suction arrangement, the at least one

adjustable suction device having a suction opening for the pick-up ballast.

A proposed solution by prior public use refers to a sand-broaching machine for track bed maintenance, which is based on the principle of an inclined bed

Conveyor line based. A front conveyor belt end is lowered between the rails and is introduced piercing into the sand fill. The sand between the rails is thus removed and disposed of by means of a lateral ejection. The disadvantage here proves the low operating speed.

The present invention has for its object to provide a way to provide a cleaning device for cleaning a track system of schüft- or free-flowing goods, especially sand, which can be operated quickly and effectively and without an increased risk of wear. Furthermore, the invention has for its object to provide a rail vehicle with such a cleaning device.

The first object is achieved with a cleaning device according to the features of claim 1. The further embodiment of the invention can be found in the dependent claims.

According to the invention, therefore, the cleaning device has a particular designed as a nozzle supply for compressed air as the driving medium and a direction of action with a main direction component in a plane parallel to the rails in a respective direction of travel, being spaced in the direction of travel before the supply to this an impact body, in particular of sheet metal , is arranged movable, wherein the impact body has a supply facing, at least partially concave baffle surface, comprising at least two cup-shaped mold parts which are used to set different, of these molded parts limited cross-sectional areas in the region of a lateral Austhttsöffnung are connected to each other movable, in particular pivotally connected, so by the compressed air in the direction of travel against the baffle surface impinges

Impurities can be deflected either to one of the two sides of the rail vehicle or the track system and discharged by the Austhttsöffnung in the environment.

The invention is based on the recognition that a mechanical removal of the discharged medium in the case of bulk or grit, in particular sand, leads to an undesirable abrasive effect in the rail-wheel system, but also within the cleaning device itself. In contrast, according to the invention, a cleaning of the track bed between the rails at a comparatively high

Delivery realized without moving elements within the cleaning device, at the same time the surface of the rails can be cleaned almost without residue of the bulk or grit. Due to the pneumatic conveying by the compressed air as a propellant medium, the achievable degree of cleaning can be adapted to the particular circumstances of contamination or the required removal rate, so as for example a quick adaptation to dry or moist bulk or spreading material and thus to the strength of the adhesion to ensure the rail.

Particularly practical proves to be an embodiment of the invention, in which the baffle body for height adjustment of Aust ttsöffnung in different vertical positions is movable, in particular pivotable. As a result, the impact body

in particular be lowered to a height with a small distance to the pollution, in particular so the surface of the sand layer, so as to realize a particularly efficient removal of pollution from the track bed. This is in addition

ensures that the particles are not whirled up in an undesirable manner, but the directional jet of the propellant and the entrained particles is reliably collected and discharged laterally. At the same time a space-saving structural design of the cleaning device is realized, which also can be easily moved or pivoted in different positions, so as to concentrate the cleaning performance, for example, on an area adjacent to the rails. It has also been shown that the impulse transmission of the compressed air to the impurity takes place faster and without loss than in a comparable cleaning device with a transversely supplied drive medium.

The impurities can be discharged by means of the impact body on both sides next to the track bed. In accordance with a further advantageous modification of the invention the impact body for discharging the rebounding objects on this, in particular bulk materials, to either one or the other side of the track system is pivotable about a substantially vertical axis, the bulk material, if necessary, be discharged to a freely selectable by the operator of the cleaning device side of the track system , In particular, this is the impact body with respect to its transverse to the rails arranged rest position in a with this an angle between 25 ° and 80 °, in particular between 40 ° and 60 ° enclosing use position pivotally.

In this case, a variant of the cleaning device is not excluded, in which the effective for the derivation of the contaminant size of the baffle by a

different relative position of the cup-shaped moldings is adjustable. As a result, the impact surface of the particular nature of the particular free-flowing

Impurities, in particular their density, can be adjusted in a simple manner. For this purpose, the surface portion of the overlap of the two mold parts is increased or decreased accordingly, so that the minimum area is not or only slightly larger than a single molded part and the maximum area corresponds approximately to the sum of all moldings.

Preferably, the baffle is not designed as a closed in the region of the outlet opening piece of pipe, but procured in the manner of an open channel. In particular, therefore, the cross-sectional area of the outlet opening is limited only in the circumferential section of the concave baffle and otherwise performed open. The lateral discharge of the impurities can thus without the risk of a possible blockage of the

Outlet opening due to unexpectedly large objects reliably performed.

For this purpose, according to a further particularly advantageous embodiment of the enclosed by the cup-shaped moldings peripheral portion of the outlet opening can be adjusted by a different relative position of the moldings. As a result, the discharged into the environment beam of contamination can be formed in the desired manner, for example, to concentrate the discharge power to a small area or to distribute over a large area. In this case, a small outlet opening is accompanied by a nozzle effect, through which impurities receive a considerable acceleration. The outlet opening can be designed to be slidable or pivotable and extendable for this purpose. In addition, it may be useful to arrange the outlet opening with a small distance to the ground and with a comparatively large

Outlet cross-section to avoid unnecessary turbulence. Preferably, for this purpose, the cup-shaped parts are pivotally and / or slidingly connected to each other in the manner of a slotted guide and can thereby in particular be moved relative to each other so that the enclosed

Cross-sectional area between the two sides of the rail vehicle steadily increasing or decreasing and in the region of the outlet opening has its minimum or maximum.

Although the moldings can be designed for this purpose as elastically deformable plastic parts, it has already proven to be particularly useful when the

shell-shaped moldings are designed as curved sheet metal parts.

In a variant, the feed for the driving medium can have a plurality of annular openings on the circumference of the feed, in particular evenly distributed nozzle openings and / or

Have driving nozzles. By the drive nozzles are each connected to its own pressure supply, the suction power can be optimally adapted to the circumstances of the particular application, in particular to the speed of the rail vehicle. In this way, even a suction is ensured, which corresponds to the longitudinal axis of the suction when additional external flow influences are inevitable.

Furthermore, it has already proven to be particularly useful if the

Cleaning device has a plurality of independently controllable, for example, separately acted upon with compressed air inlet openings for the propellant.

Preferably, also the supply for the compressed air or the driving medium relative to the track bed in different vertical distances can be fixed so as to be able to easily adjust an optimal distance of the feed or a suitable orientation relative to the surface of the debris or grit.

Of course, the cleaning device may comprise a plurality of longitudinally arranged in different longitudinal planes in different planes inlet openings, which preferably open into the same outlet, so that a layered removal of the suction medium is gradually enabled until complete removal by a plurality of inlet openings in succession.

The second task, one equipped with such a suction

To provide a rail vehicle, with the grit can be removed quickly and efficiently from the track bed and the rail surface, is realized according to the invention, in that the rail vehicle is equipped with a cleaning device which has a feed, in particular as a nozzle, for compressed air as the driving medium and a direction of action with a main directional component in a plane parallel to the rails in a respective direction of travel of the rail vehicle, wherein

Direction before feeding to this spaced a baffle, in particular made of sheet metal, is movably arranged, wherein the baffle body facing the feed, at least partially concave baffle comprising at least two cup-shaped mold parts, the setting of different, limited by these moldings cross-sectional areas in the area a lateral outlet opening are mutually movable, in particular pivotally connected, so that by the compressed air in the direction of travel against the impact surface impinging impurities either to one of the two sides of the rail vehicle or the track system distractable and by the

Outlet opening are dischargeable into the environment.

It proves to be expedient if, in the direction of travel of the rail vehicle in front of the cleaning device, a slider is provided so as to be able to laterally push off a considerable amount of dirt from the track system. As a result, the cleaning can be essentially limited to the areas lying between the rails below the level of the rail surface, so that the cleaning performance can be increased overall in relation to the distance cleared in a predetermined time.

For this purpose, the slider can be adjusted, so that the bulk material is displaced either to one of the two sides. As a result, the cleaning device can be optimally adapted to the respective conditions of use. In addition, it is also possible to provide flexible guide elements, for example brushes, in order to be able to supply the spreading material to the at least one inlet opening in a targeted manner.

The invention allows for various embodiments. To further clarify its basic principle, one of them is shown in the drawing and will be described below. This shows in

The cleaning device 1 according to the invention for cleaning a track system 2 with a rail 3 and track sleepers 4 having track bed is shown below with reference to Figures 1 to 9 in more detail. The cleaning device 1 is integrated in a rail vehicle 5 and preferably serves to remove non-pouring or free-flowing impurities, in particular sand, from the track bed. For this purpose, the cleaning device 1 has a feed 6 for compressed air as the driving medium, in the direction of travel 7 of the rail vehicle 5 obliquely from above on the surface of the contaminated

Track 2 directed exit. In this case, the cleaning device 1 is configured redundantly such that one of two feeders 6 is activated in both possible directions of travel 7.

As can be seen in particular in FIGS. 2 a and 2 b, in the direction of travel 7 in front of the feed 6, a distance a to this one in FIGS. 3 to 9 is increased

shown baffle 8 is pivotally mounted about a vertical axis 9.

In accordance with a selected side angle α of the pivoting position, the ejection of the free-flowing impurities deflected on the impact body 8 takes place as an exit jet 10, optionally to one or the other side of the vehicle I, r. The structural design of the impact body 8 will be further clarified below with reference to Figures 3 to 9. As can be seen, the baffle 8 has a feed 6 facing at least

To form a desired of these mold parts 12, 13 in the region of a lateral outlet opening 14 bounded cross-sectional area 15, these mold parts 12, 13 are pivotally connected relative to each other about an axis 16 pivotally. Thus, by allowing the outlet opening 14 to be enlarged or reduced, the outlet jet 10 can be shaped in the desired manner. For example, such a thin sand blast of high speed can be generated to achieve a wide ejection. Likewise, a cloud-shaped

Exit beam 10 are generated. In addition, the setting of the outlet opening 14 is independent of the side angle α of the baffle body 8. Rather, the effective for the derivation of contamination size of the baffle 1 1 is determined by a different relative position of the cup-shaped mold parts 12, 13.

The supply 6 for compressed air shown in Figure 1 will be explained in more detail below with reference to Figures 10 to 12, each of the feed 6 and the thereto

opposite arranged baffle 8 show. As can be seen, the feeder 6 has a plurality of conduits 17 each opening into a nozzle 18. Each of these nozzles 18, depending on the respective distance to the baffle body 8 and the formation of the mold parts 12, 13 in different vertical distances relative to the baffle 8 can be fixed. For this purpose, each nozzle 18 is connected to a pivot arm 19, which is deflectable by a drive, not shown in the direction of arrow 20. Regardless, the nozzle 18 is pivotable about an axis 21 in the direction of arrow 22 to adjust a desired direction of the exiting air flow against the baffle body 8 can.
