Description

The invention relates to a liftable support device with the features of the preamble of claim 1 and a rail vehicle in the form of a pocket wagon with at least one such support device.

In the prior art, in connection with the loading of a rail vehicle with cargo by means of a lifting device, cargo in the form of cargo that can be craned directly and cargo that cannot be craned directly is known.

Immediately craneable cargo refers to a cargo which itself has gripping edges for a lifting device, that is to say can be loaded by a lifting device essentially without further aids. A cranable semi-trailer can be cited as an example of a load that can be craned directly.

Cargo that cannot be craned directly refers to cargo that does not itself have any gripping edges for a lifting device. Such cargo is often loaded by means of a lifting device, the lifting device having gripping edges for a lifting device. Such a lifting device can therefore not be made craneable directly cranable cargo. An ordinary semi-trailer or a car, for example, can be named as an example of a load that cannot be craned directly.

FR 2 965 257 A1 shows a liftable support device with a first pair and a second pair of gripping edges, which are formed on two spaced apart and interconnected longitudinal members. When loaded on a rail vehicle designed as a pocket wagon, both pairs of gripping edges are located inside the pocket of the pocket wagon.

A liftable support device with the features of the preamble of claim 1 is based WO 2016/141399 A1 emerged. This document describes in particular (cf. page 4, line 28 to page 5, line 2) six pairs of gripping edges (referred to there as "receiving pockets"), all of which, viewed in the first direction, are arranged within the length of the at least two longitudinal members, so that slightly different center of gravity of the carrying device loaded with cargo can be taken into account.

The object of the invention is to provide a carrying device that can be loaded with goods of a first type (e.g. in the form of containers, semitrailers, tractors, tractors, buses or light trucks) and a second type (e.g. in the form of short Trailers) can be loaded and safely lifted by a lifting device, the center of gravity of the load of the first and second type differing so greatly from one another that safe lifting using the same carrying device according to the prior art would not be possible.

This object is achieved by a lifting support device with the features of claim 1.

A liftable carrying device with the features of claim 1 enables an improved adaptation to very different centers of gravity, since the first pair of gripping edges viewed in the first direction is arranged or can be arranged outside the length of the at least two longitudinal members, so that optionally cargo of a first type and cargo one second type with the same support device by a lifting device can be safely lifted (in particular while maintaining a horizontal orientation of the load during the lifting process).

Protection is also sought for a rail vehicle in the form of a pocket wagon, with a bag and with at least one carrying device according to the invention, which over the entire length of the drive-on support is arranged inside the pocket and wherein the first pair of gripping edges viewed in the first direction is arranged or can be arranged outside the pocket.

The distance between the gripping edges in the first direction should be selected so that two gripping edges arranged at a distance from one another in the first direction along a common longitudinal member are used by a lifting device (together with the corresponding two gripping edges arranged on the other longitudinal member) to carry out a lifting process for loading - or unloading are usable.

Advantageous embodiments of the invention are defined in the dependent claims.

angeordnet sind.The liftable support device has a support frame 4, which in turn has at least:

• two longitudinal members 5, each with a length L _T running along a first direction R ₁ and spaced apart from one another in a second direction R ₂ running at right angles to the first direction R ₁ , which are connected to one another
• a drivable support 6 for the load 3, extending with a length L _A along the at least two longitudinal members 5 in the first direction R ₁ and running between the at least two longitudinal members 5
• a first pair P ₁ and a second pair P ₂ of gripping edges 7 for the lifting device, wherein
• the gripping edges 7 of the first pair P ₁ and the gripping edges 7 of the second pair P _2, viewed in the first direction R ₁ , are arranged at a distance from one another and
• the gripping edges 7 of each pair P _1, P ₂ in the second direction R ₂ looking at each other are opposed to
• the second pair P ₂ of gripping edges 7, viewed in the first direction R ₁ , is located within the length L _{T of} the at least two longitudinal members 5

wherein the first pair P ₁ of gripping edges 7 viewed in the first direction R ₁ outside the length L _{T of} the at least two longitudinal members 5
are arranged.

In this first embodiment of the invention, the first pair P ₁ of gripping edges 7 is formed on a respective carrier extension 8, which here are releasably fastened to fastening points 14 arranged in the longitudinal members 5 by means of a locking device in the form of bolts.

In this first embodiment of the invention, the second pair P ₂ of gripping edges 7 are each formed on a carrier attachment 9, which here are releasably fastened to fastening points 14 arranged in the longitudinal members 5 by means of a locking device in the form of bolts.

In this first embodiment of the invention, a third pair P ₃ of gripping edges 7 is formed on each carrier extension 8.

In this first embodiment of the invention, a fourth pair P ₄ of gripping edges 7 is formed on each of a carrier attachment 9, which here are releasably fastened to fastening points 14 arranged in the longitudinal members 5 by means of a locking device in the form of bolts.

Either a set consisting of the first and the second pair P ₁ , P ₂ of gripping edges 7 or a set consisting of the third and the fourth pair P ₃ , P ₄ of gripping edges 7 can be used by a lifting device. Due to the different placement of the different pairs P ₁ , P ₂ . P ₃ , P ₄ of gripping edges 7 in the first direction R ₁ can thus be adapted to different overall centers of gravity of the load 3 and the carrying device 1.

In this first embodiment of the invention, the first and second pairs P ₁ , P ₂ of gripping edges 7 are arranged at a common height (measured from an underside of the support device 1) which is greater than a common height of the third and fourth pair P ₃ , P ₄ of gripping edges 7. This is not absolutely necessary.

An optional connecting part 15 connects the two carrier extensions 8 to one another and serves to increase the mechanical stability.

Like in particular from Figure 2 As can be seen, in this exemplary embodiment the drivable support 6 extends over a length L _A which is the same as the length L _{T of} the longitudinal members 5. However, in an exemplary embodiment not shown, a drivable support 6 with a shorter length L would be possible _A to use.

In the Figures 3 and 4th it can be seen that the lifting support device 1 in this exemplary embodiment has support surfaces 11 by means of which it can be set up directly on a terminal floor 12.

Figure 6a shows an example of one of the two carrier extensions 8 in isolation.

Figure 6b shows an example of one of the four carrier attachments 9 in this exemplary embodiment in isolation.

Figure 7 shows the support device 1 of Figures 1 to 5 and 7th , wherein the carrier extensions 8 and the carrier attachments 9 have been removed. In this state, the support device 1 can of course not be lifted by a lifting device.

Unlike in the Figures 1 to 5 and 7th As shown, the carrier extensions 8 and / or the carrier attachments 9 could be arranged in a non-detachable, cohesive manner (e.g. by welding) on the longitudinal members 5.

Figure 8 shows an example of the liftable support device 1 according to the first embodiment (with an optional additional connecting part 15 being shown) inserted into a pocket 13 of a rail vehicle 2 designed as a pocket wagon. It can be seen that the gripping edges are located 7 of the first pair P _{1 are} outside the pocket 13 and the gripping edges 7 of the second, third and fourth pairs P ₂ , P ₃ , P _{4 are} inside the pocket 13. Of course, all gripping edges 7 of all pairs P ₁ , P ₂ , P ₃ , P _{4 are arranged} above the contour of the side wall of the pocket wagon so that they are accessible to a lifting device. In contrast to what is shown, it can be provided that the gripping edges 7 of the first pair P ₁ of gripping edges 7 are each arranged on a component which is formed in one piece with the respective longitudinal member 5.

The Figures 9a-c show a second embodiment of a liftable support device 1 according to the invention.

The only difference to the support device 1 after Figures 1 to 5 and 7th consists in that here a total of only two pairs P ₁ and P _{2 are provided} on gripping edges 7, of which two gripping edges 7 arranged along a longitudinal member 5 are formed on a common component 10, the common component 10 viewed _{in the first direction R 1} at least two different positions (here by way of example at three different positions) one of the two longitudinal members 5 can be releasably connected to the longitudinal member 5 by means of a locking device (e.g. lockable bolts).

In a first position ( Figure 9b ) of the at least two different positions of the common component 10 protrudes on the longitudinal member 5 in the first direction R ₁ , one of the gripping edges 7 beyond the longitudinal member 5, while the other gripping edge 7 is located within the length L _{T of} the longitudinal member 5.

In a second position ( Figure 9a ) of the at least two different positions of the common component 10 on the longitudinal member 5, _{viewed in the first direction R 1} , both gripping edges 7 are at least partially within the length L _{T of} the longitudinal member 5.

In a third position ( Figure 9c ) of the at least two different positions of the common component 10 on the longitudinal member 5, _{viewed in the first direction R 1} , both gripping edges 7 are located completely within the length L _{T of} the longitudinal member 5.

By means of the first, second and third position, depending on the load 3, a different overall center of gravity of the load 3 and the liftable carrying device 1 can be achieved.

Based on the embodiment of Figures 1 to 5 and 7th will be in the Figures 10a and 10b two applications of one and the same liftable carrying device 1 with different loads 3 are shown. The same applications are of course also with the embodiment of FIG Figures 9a-c possible.
