Method and apparatus for moving transport containers - Förfa-rande och anordning för överföring av transportcontainers

The invention relates to a method and a device for transferring transport containers from a container transport vehicle to a train or from a train to a container transport vehicle, respectively.

The transfer of transport containers between a container transport vehicle and a train is a problem at container loading and unloading points where no suitable lifting equipment is available. Several solutions have been proposed to overcome this problem, but none of them has proved to be satisfactory in practice.

It is known from the prior art that min. a solution in which a horizontally pivoting platform for transport containers is provided on the train carriage. When loading or unloading, the pallet is turned at an acute angle to the longitudinal axis of the carriage, whereby the container transport vehicle can be reversed parallel to the turned pallet against the end of the pallet and move the container from one means of transport to another in a known manner.

However, there are several disadvantages associated with this known structure, the most significant of which, in addition to the high cost of the structure, is the lack of stability of the carriage when the platform is turned, as a result of which the carriage easily overturns.

In order to eliminate the above-mentioned drawbacks, the method according to the invention provides that the train carriage and the container transport vehicle are driven relative to each other so that their sterns meet, the container being pushed parallel to its longitudinal axis from the container transport vehicle to a train with fixed, longitudinal axial guide rails and 72471 Liftable wheelsets for lifting a container onto the wheelsets during transfer, or from a train to a container transport vehicle, respectively.

The method according to the invention is further characterized in that the transport container is moved from one wagon to another on the basis of raised gears. In this way, the transport containers can be transferred to the train one at a time without moving the wagons.

The device according to the invention for transferring transport containers from a container transport vehicle to a train or from a train to a container transport vehicle, respectively, is characterized in that the railcar is provided with fixed guide rails along the longitudinal axis of the carriage for transport containers and liftable wheels to lift the container.

In a preferred embodiment of the device according to the invention, it is arranged that at least one gear in each carriage is arranged to be towed. This makes it easier to move transport containers from one wagon to another because no separate traction devices are required.

In the following, the invention will be described in detail with reference to the accompanying drawing.

Figure 1 shows a partial cross-section of the upper part of a train carriage with its loaded containers, in which the carriage is provided with guide rails for transport containers according to the invention.

Fig. 2 shows a similar cross-section of the upper part of the train carriage as in Fig. 1, but at the point where the lifting gear is arranged.

Figure 3 shows a section along the line 3-3 in Figure 2.

In Fig. 1, reference numeral 1 schematically denotes the upper part of the supporting frame structure of a train carriage shown in a partial cross-section. Mounted on the frame structure 1 are guide rails marked with reference number 2, along the longitudinal axis of the carriage. In the embodiment example shown, the rails 2 are formed by a square tube beam 3 and an L-profile 4 welded on it.

The guide rails 2 on the train carriage are supported by a transport container marked with the reference number 5 in Fig. 1 by means of support rails 6 under the container.

Figure 2 shows a similar partial cross-section to Figure 1, but the section is from a different point. In Fig. 2, reference numeral 7 denotes a gear which can be lifted to lift the transport container 5 off the horizontal side of the L-profile 4 acting as a guide rail during the movement of the container 5 to facilitate the transfer.

In the structure shown in Figures 2 and 3, the gear 7 is formed by two roller wheels 8 and a shaft 9 connecting them fixedly. The shaft 9 is in turn rotatably mounted on the vertical side of the L-profile 4, on a flange 10 rotatably mounted on the shaft 11. to the hydraulic cylinder 12 fixed to the car body so that the roller wheels 8 of the gear 7 can be lifted through an opening arranged in the horizontal part of the L-profile 4 to raise the container 5.

There are usually 5 or 6 gears 7 in each train car, depending on the length of the car. The wheelsets may be freely rotatable, but preferably at least one wheelset in each carriage is arranged to be driven by, for example, an electric or hydraulic motor, so that no separate traction or pushing devices are required for moving the containers, except for the devices in the container transport vehicle itself.

The lifting capacity of the gear 7 is dimensioned so that when moving the container 5 from one wagon to another, the container hits the guide rails 2 of the next wagon despite the wagon springs. The vertical side of the L-profile 4 laterally guided by the container 5 must of course be high enough to be raised on the wheels 7 during transport. fully controlled.
