Description

The invention relates to a work car for track construction in railway lines according to the preamble of claim 1.

Trains are used for railway track construction. These consist of a series of work cars, which perform a variety of work, which are necessary for the track construction. This concerns on the one hand the substructure as well as on the other hand the track of the railway line located on the substructure.

As a work car for this track construction in railway lines, the so-called material handling silo wagons (MFS wagons), material transport wagon (MT wagon), etc. are known, which can temporarily store and transport the required materials on these construction sites in the track construction sector , These work cars serve - as stated - to transport the material on the track axis in one direction or in different directions, without having to leave the track restriction profile (clearance gauge) with the material. The work cars are used in a row for transport and bunkering of the materials.

In the case of these works, in particular in the area of the conveyor belts, the transfer and the conveyance of the materials generate dust. Depending on the weather and dryness of the material, these dust developments can take on considerable proportions. This is a workload for the workforce, the environment and nature both in terms of work and personnel.

The US 5,357,867 A discloses a work train with work car for rehabilitation of a railway line of the type specified. In order to curb the development of dust when the track, the track is previously sprayed with water via nozzles of the work car. These spray nozzles are fed with water from water tanks.

On this basis the invention has for its object to further develop the working carriage for track construction in railway lines of the type previously specified in such a manner that the dust is further reduced at source.

The technical solution is characterized by the features in the characterizing part of claim 1.

As a result, a dust protection device for work cars for track construction in Bahnstrekken especially in the form of MFS cars or the like. Created, which has a dust minimization within the work car result. This dust reduction creates a dust discharge for the workforce, for the environment as well as for nature both in terms of work and in terms of personnel. Overall, this improves the working quality of the work car.

In a first variant, it is proposed according to claim 2 that the device for controlling the dust formation is a device for spraying the materials with water. Preferably, according to the embodiment of claim 3, this device is formed by spray nozzles. The basic idea of these water spray nozzles lies in a targeted arrangement in dust-relevant areas, that is, where by the transport or - generally - by the movement of the materials dust sources are present. The water spray nozzles are arranged according to the requirements at corresponding points of the conveyor belts. This can be done above or beside or on or on the conveyor belts. The supply of water to the spray nozzles is made by supply lines to the car by means of an electric or other mechanical pump.

According to the embodiment of claim 4, the work car has its own water tank for the storage of water. This means that each work car, which is equipped with a corresponding water spray, has its own water tank.

As an alternative to their own water supply of the respective work car according to the development in claim 5, the corresponding work cars of the train over a central water truck to be supplied with water. In this case, the work car to be supplied with water by means of a coupling of the individual cars are connected to the water cycle. The pumping power for the water supply and the associated control electronics can hereby be centrally located on the water truck. From this central watercraft from the respective work cars are thus supplied with water.

A development of the above-described water truck proposes according to claim 6, that this is queued in a number of other work cars other type of work train and that this watercraft has conveyor belts for transporting materials of the adjacent other work cars. This means that the watercraft is designed with additional additional logistics functions of a modular design work group of individual machines and for logistical diversion, transit and transfer of material flows. Thus, the separate watercraft are designed with logistical mechanical activities for the special Materialstromlinienförderung. This is necessary when very long modular train assemblies are used. For here it can come from logistical and operational technical constraints that the watercraft must be incorporated within a train. It is then necessary to classify the trained as well as specially and separately adapted watercraft in the train.

The water truck thus has conveyor belts for transporting materials of these adjacent other work cars. By this is to be understood that on the watercart on both sides different types of work, such as MFS wagon or the like. Connect, with the need to transport the materials along the work train, without the watercraft is an obstacle and interruption for this material transport and the Material transport there stagnates. In this respect, this preferred development proposes that the materials can be transported to some extent, without the water truck is an obstacle.

As a result, a total of a logistically flexible expandable watercraft is created. Thus, the logistical possibilities of the water truck are extended so that the material flows can be performed by the water truck, namely material flows, which have to do with the processing for removed ballast and / or other substructure materials. The water truck thus becomes part of a flexible logistical transport and transport route within a modularly flexible train. It is thereby possible, within an arbitrarily lined train of material-conveying silo wagon or the like. To be able to line the watercars, without in the ranking of the work car To have constraints in the material flow. As a result, the possible material delivery streams of the adjacent material conveyor trolleys can be variably guided by the water trolley so that the water trolley acts as a pass-through module for the materials in all possible conveying directions of adjacent material trolleys. Due to the additional equipment of the water truck with appropriate conveyor belts, the adjustment of this water truck within an arbitrarily lined train with material trolley is possible. As a result, any number of water trucks in the conveyor line of MFS cars or the like can be adjusted without hindering or affecting the flow rate performance. Thus, any sequence of different machine technology in a modular system within a composite of material trolley is possible without negative influences and constraints on the material flows of the adjacent and lined material trolley to have. This allows in many ways entirely new possibilities of machine assortments and logistic applications in the track construction sector with modular technology.

Since thus the water truck is equipped with appropriate, in particular reversible conveyor belts for transporting the materials, dust can also occur here. This means that this watercraft is appropriately equipped with means for controlling the dust formation of the materials, for example water spray nozzles.

A second variant of the device for controlling the formation of dust proposes claim 7 in the form of a suction device for the dust. This means that this device effectively acts as a vacuum cleaner and thereby reduces the accumulated dust to a minimum. The use of such a suction device with respect to the water spray nozzles has the advantage that no water is required for the dust binding, which is obtained accordingly.

Finally, a third variant of the device for controlling dust formation proposes claim 8 in the form of a cover in the area of dust development. These dust covers also have the advantage of effective dust prevention.

The above-described three variants for controlling the development of dust can be used individually or optionally also in combination.

Fig. 1 shows a composite of two work cars 1 in the form of so-called material handling silo wagons (MFS cars), this representation of the two work cars 1 should be purely exemplary, as these work cars 1 may be formed. In principle, these work cars 1 are movable on a railway track from a substructure 2 with track 3 located thereon. The work car 1 in this case have one or more, mutually parallel bottom conveyor belts 4, end transfer belts 5 (which are formed in the embodiment as retractable carriage with a horizontal axis up and down pivotally mounted cantilevers and which optionally additionally on a vertical axis of the carriage laterally can be pivoted) and finally roof conveyors 6. In this case, the roof conveyor belt 6 is shortened in the left work car 1, while it is formed continuously in the right work car 1. At the end, the roof conveyor belts 6 can have upwardly and downwardly pivotable transfer conveyor belts 7. All the above-described conveyor belts are preferably formed reversible.

Starting from that shows Fig. 2 the equipment of these two work cars 1 with a device for controlling the dust development of transported on the conveyor belts materials in the form of spray nozzles. These are arranged at the points of the work car 1 and oriented accordingly, where dust development of the transported materials can occur. Associated with the two work cars 1 is a water tank 9, which supplies the spray nozzles 8 with the use of appropriate pumps and a controller with water.

An alternative to this water tank 9 sees the embodiment in Fig. 3 in front. Again, a work car 1 with spray nozzles 8 is provided again. For the water supply, however, a separate water truck is used 10. As in particular in the illustration in Fig. 4 can be seen, this watercraft 10 is part of a composite of several cars of the work train, the water truck 10 is centrally responsible for the supply of the spray nozzles 8 with water of the work car 1. Accordingly, this watercraft 10 has a central control electronics 11.

The peculiarity of this water truck 10 is in Fig. 5 and FIG. 6. Because the water truck 10 is equipped with conveyor belts 12 in the bottom area below the water tank and with conveyor belts 12 in the roof area above the water tank. These conveyor belts 12 are designed and intended to be able to transport material 13 from one side of the water cart 10 to the other side of the water cart 10.

Specifically, in the embodiment in Fig. 5 a transport of the material 10 is provided in the roof area, while in the embodiment in Fig. 6, the material 13 is fed by means of a transfer conveyor belt of the adjacent work car the water truck 10 to pass through the material on the bottom conveyor conveyor belts 12. The discharge takes place via an inclined transfer conveyor belt. In order to be able to position the transfer conveyor belt of the adjacent work car in this case, the water truck at the end has a receiving device for the support of the transfer conveyor belt of the adjacent work car.

The two representations in Fig. 5 and 6 are purely exemplary. The transport of the materials 13 can be done with appropriate conveyor belts in other ways.

In another option, the attachment of additional conveyor belts on the individual components is conceivable. These correspond in their single-action technical function to the systems already mentioned and have the purpose of expanding the number of fabric layers and material flows that are available for an execution performance. The number of conveyor belts can be arbitrary according to the existing technical Be provided space. So two or three or more conveyor belts can be arranged side by side.

Finally, the individual modules can be electronically coupled to supply the operations of a partial or full automation of the individual components of the machine network.
