EP1391364B1 - Dismountable railway vehicle, comprising a lifting platform - Google Patents

Abstract

The robot vehicle (15) may carry a powerful lighting unit and has endless tracks (16) to enable it to be maneuvered at a working site. The transport trolley has a lifting plate (1) on longitudinal beams (14) supported on hand operated lifting gear at each end. There are flanged wheels at each end, running on railway rails (13). Side-members join the lifting gears at each end. When the plate is lowered, the vehicle can climb onto the trolley from an embankment (17). The plate can be raised and shifted sideways to allow access from a station platform.

Description

The invention relates to a rail-bound transport vehicle according to the preamble of patent claim 1.

With the subject of DE 197 03 701 A1 a two-axle chassis for rail-mounted transport systems has become known, which is suitable for the transport of heavy loads. In a chassis frame, the wheelsets are added, at least one of the wheelsets is driven directly via a final drive. The chassis frame is divided into two halves.

Such a biaxial chassis is relatively bulky and heavy and not dismountable. The chassis must be built so stable that, for example, a self-propelled vehicle which is to be driven onto the transport vehicle with its shear and torsional forces does not damage the chassis frame of the rail-mounted transport vehicle, bends or even destroyed.

For this reason, such rail-mounted transport vehicles must be built very stable and torsionally stiff to allow the driving of crawler tracks.

It is accordingly not possible with such a transport chassis, for example, on the open road a self-propelled vehicle - for example, with a crawler chassis - drive on this rail-bound transport vehicle.

No. 4,938,643 discloses a self-propelled, rail-bound transport vehicle for crane vehicles with a lifting and lowering transport plane, wherein the crane vehicle can perform work operations from the transport or unloading position.
The crane truck can lift the transport vehicle off the rails before and after transport at any suitable position for trains to let happen smoothly. A central locking mechanism on the transport plane locks the crane vehicle to prevent unwanted forward and backward movement during transport.

EP 0 900 707 A1 discloses a articulated trolley for combined loading traffic, in particular of road vehicles, which has vertical lifting mechanisms for raising and lowering the transport plane and parts of the front sides of the transport plane are mounted horizontally rotatably on a chassis / bogie.

The disadvantage of the two above-mentioned inventions is that both transport vehicles are constructed relatively expensive and assembly / disassembly of the transport vehicle can be realized only with great technical effort. A possible rapid removal of the transport vehicle with little technical effort, however, makes sense for the described reasons of the present application. In addition, EP 0 900 77 A1 has the disadvantage that the disclosed articulated vehicle is not self-propelled and an auxiliary drive (towing vehicle) is necessary for moving the transport vehicle.

The invention is therefore the object of developing a rail-mounted transport vehicle of the type mentioned so that the transport vehicle according to its intended design has a structurally simple structure and can be used at any point of a rail system for heavy loads.

The object is achieved by a transport vehicle according to claim 1.

With the given technical teaching, there is now the significant advantage that one provides a rail transport vehicle, which is suitable by means of a liftable and lowerable lifting platform, any vehicles and loads from different Auffahr- or Aufsetzhöhen aufnimmt which is suitable due to its structural design

For the sake of simpler description, it will be assumed in the following description that a self-propelled vehicle, preferably a caterpillar-driven self-propelled vehicle, is to be driven onto the rail-bound transport vehicle according to the invention. However, the invention is not limited thereto, all vehicles and loads can be placed on the rail-bound transport vehicle according to the invention at any height or driven up.

According to a preferred embodiment of the invention, it is provided that the rail-bound transport vehicle is designed to be self-propelled. For this purpose, a traction drive is provided which preferably consists of an oil-hydraulically driven motor which is non-rotatably connected to one of the axles of the respective wheelset.

The oil engine is preferably powered by the self-vehicle itself if it is an oil hydraulic vehicle. It is then a connection hose from the supercharged self-vehicle to the drive of the transport vehicle out, so that the oil pressure of the charged self-vehicle for the drive of the transport vehicle is used.

In another embodiment, of course, other travel drives can be provided, such. Friction drives, wherein via a corresponding friction wheel of the supercharged self-vehicle, this rotation of the drive axle of the self-vehicle is transmitted to the axis of the transport vehicle.

It can of course be used any other type of traction drive for the transport vehicle according to the invention.

The arrangement of a lifting frame in the frame of the transport vehicle has the significant advantage that the lifting frame can also be placed directly on the rails of the track bed. This now for the first time gives rise to the possibility that a self-propelled vehicle can be driven directly onto the lifting platform lowered onto the rail bed, without any impact, twisting or destructive forces being transmitted to the frame of the transport vehicle itself.

The actual load transmission takes place here from the approaching self-propelled vehicle directly onto the lifting platform lowered onto the rail bed, so that the frame of the transporting vehicle itself does not participate in the load transmission of the approaching self-propelled vehicle.

This results in a further essential feature of the invention, namely, that the transport vehicle can therefore be designed easily dismantled and transportable. This is for the first time possible in that just Auffahrlasten which could be exercised by a self-propelled vehicle on the lifting platform on the support frame, not transmitted to the support frame. It is just - as shown - the vehicle ascended to the patch on the track bed lifting platform, all parts of the support frame of the transport vehicle can be removed in this case.

So it is the mere lifting platform on the surface of the rails, and the self-vehicle to be charged moves independently on the lifting platform, there turns and then sits in the vehicle longitudinal direction on the lifting platform. It will then bring the corresponding frame parts of the frame of the transport vehicle and put together, for example, the frame consists of a front and a rear Stirnbock on which Stirnbock simultaneously the respective wheelset is arranged.

The two Stirnböcke are plugged together by side bars arranged parallel to each other, with any plug and lock connections can be provided.

Such plug or lock connections can be simple plug-in pins which engage in associated recesses. Quick-release fasteners may be used, e.g. Eccentric quick fasteners, cleats, screw caps and the like. Now that the front forehead brace has been moved to the front of the lifting platform, the rear forehead bracket to the rear side of the lifting platform and the two Stirnböcke were plugged together by the respective side rails, now the lifting drive can be mounted. This consists in the simplest case of a Kettenhubwerk, which will be described later with reference to the drawings.

Instead of a Kettenhubwerkes of course, all other height-adjustable hoists can be used, such as hydraulic hoists, Spindelhubwerke and the like.

By operating the hoists the lifting platform is now raised accordingly and moves so in the mated chassis of the transport vehicle upwards, which at the same time the charged load (Self-vehicle) is raised. As a result, the transport vehicle is brought into a state capable of driving and can now with its own, autonomous traction drive, which is preferably powered by the self-vehicle, proceed.

A significant advantage of the rail transport device according to the invention is therefore that it is easy to disassemble and therefore on the spot - where a load or a self-vehicle is to be charged - can only be put together.

The particular advantage of easy dismantling results also in the case of rail accidents. In this case, it may be provided that a rescue device is transported on the rail with such a transport vehicle and is moved to the scene of the accident. At the accident site, however, most of the tracks are destroyed, so that a further advance of the transport vehicle is no longer possible. Thanks to the lifting platform and the easy dismantling of the transport vehicle, the rescue device can now be set down on the track and automatically advance to the scene of the accident. The transport vehicle can then be disassembled, for example, and also rested on the rail body beyond the accident site and moved on.

Another advantage results from the arrangement of the lifting platform in that it is now possible for the first time to charge such self-propelled vehicles from different collision heights. For example, such a vehicle can also be used in subways, where quite different platform heights exist in comparison to the person-bound railroad track heights. Thanks to the height adjustability of the lifting platform, it is therefore also possible to drive up such a self-propelled vehicle from a subway platform, wherein a loading ramp is used.

Such a rail transport vehicle preferably consists of a total of five parts, and can be accessed by five persons via platforms and other obstacles, such as stairs, underpasses or accident sites are worn and then built on the spot.

If the drive is via an oil-hydraulically driven motor (compact motor with integrated brake), the speed of the transport device can be around 30 km / h.

During driving, the lifting platform is always in the lower position about 100 mm above the track to allow appropriate driving.

All information and features disclosed in the documents, including the abstract, in particular the spatial design shown in the drawings, are claimed to be essential to the invention insofar as they are novel individually or in combination with respect to the prior art.

In the following the invention will be explained in more detail with reference to drawings showing only one embodiment. Here are from the drawings and their description further features essential to the invention and advantages of the invention.

In Figure 1 is shown schematically that a Sälbstfahrzeug 15 can be driven onto the transport vehicle 20 according to the invention on a free route. After the support frame of the transport vehicle 20 is easily dismantled, this could never absorb the forces arising during the startup. Instead, a very rigid and stable torsion-resistant support frame would have to be created which would prohibit the transport and dismantling of the transport vehicle.

For this reason, the invention provides that initially on the rails 13 of a track bed, the lifting platform 1 of the transport vehicle 20 is discontinued, wherein the lifting platform 1 is stiffened from below by mounting rails 14.

The self-vehicle 15 to be charged is now moved laterally over the embankment 17 and moved in the direction of arrow 18 to the lifting platform 1. The crawler undercarriage 16 of the self-propelled vehicle 15 now exerts correspondingly high displacement and twisting forces on the lifting platform 1, but these forces are transferred to the rails 13 and not to the supporting frame of the transporting vehicle 20 because it is completely removed.

2 shows the easy dismantling of the transport vehicle 20. There is a front forehead brace 2, on which a front wheel 25 is arranged. The forehead has an approximately rectangular support frame, wherein at the top of the support frame, a part of the Hubtragwerkes is arranged. This consists in a preferred embodiment of a winch gear 6, which has sprockets 7 via which in each case a round link chain 19 runs.

In each free lower end of the round link chain 19, a hook 23 is arranged in each case.

The other Stirnbock 4 is formed in the same way.

At the end faces of the lifting platform 1 associated and spaced from each other to each other arranged suspension lugs 24 are fixed, in which the hooks 23 of the respective round link chain 19 are mounted.

In order to connect the two end brackets 2, 4 with each other plug-in receptacles are provided. In this case, each plug-in pin 21 are arranged on the left and right side rails 3, 5, which engage in associated plug-in receptacles 22 on the end blocks 2, 4. In this way, the two end brackets 2, 4 can be easily assembled over the two side rails 3, 5.

FIG. 3 shows the finished assembled vehicle, wherein it is merely indicated that the round link chains 19 run over the associated chain wheels 7 and engage with their hooks 23 in the associated eyelets 24 of the lifting platform 1.

FIG. 1 now shows that the vehicle has been completely dismantled and only the lifting platform 1 has been set down on the rails 13 alone.

Once the self-vehicle has been driven in the direction of arrow 18 on the lifting platform 1, it is rotated with its own drive, so that it is in the direction of travel of the rails 13. It is then mounted as shown in Figures 2 and 3 of the support frame in which the front brackets 2, 4 are moved from the front and rear to the lifting platform 1 and these are laterally interconnected by the side rails 3, 5. It Then the round link chains 19 are hooked with their hooks 23 in the eyelets 24 and the still lying on the Hubplattform1 and the track bed vehicle can now be raised accordingly in the support frame of the transport vehicle 20.

FIG. 4 shows that when the lifting platform 1 a is raised, it is possible by means of a loading ramp 10 to drive up a self-propelled vehicle 15, for example, from a platform heel 9.

FIG. 5 shows that in the transport state on the rail the self-propelled vehicle 15 then rests on the lowered lifting platform 1 b and can thus be transported safely and stably.

The two side rails 3, 5 are pulled down deeply and do not interfere with a lateral approaching a self-propelled vehicle 15 in the already assembled transport vehicle 20. Namely, FIGS. 4 and 5 show that it is not always necessary to solve the problem when the lifting platform 1 is placed on the rails 13 and then the self-propelled vehicle 15 is driven there.

Rather, it is shown in FIGS. 4 and 5 that a self-propelled vehicle 15 can also be driven onto the lifting platform 1 already mounted and raised in the transport vehicle 20.

Of course, a startup of the self-vehicle 15 at lower platform heels 9 is possible, in which case, for example, the lifting platform 1 is raised only in the middle position. Thanks to the deep-drawn spars results in a good ride-through from the side of the transport vehicle 20 on the lifting platform. 1

FIGS. 4 and 5 also show that a motor drive 8, which operates, for example, with an oil-hydraulically driven motor, is arranged on at least one wheelset 25. This engine is connected via a high-pressure line to the traction drive of the self-propelled vehicle 15, so that the oil pressure of the Self-vehicle 15 is used for the drive of the transport vehicle 20.

FIGS. 6 and 7 show, in slightly modified embodiments, a self-propelled vehicle 15 which has been raised on the lifting platform 1 and which is aligned in the direction of travel.
