The present invention relates to an apparatus for attaching cargo carriers to a railway carriage, which cargo carriers can be loaded and unloaded from the longitudinal side of the carriage.

The object of the present invention is to enable, in particular, the road transport of large cargo containers (containers) by means of step transport vehicles and the transfer and loading of containers to a railway carriage directly from a step transport vehicle without the need for a crane, forklift or similar lifting means. It is therefore intended that the tank can be moved to the railway carriage from one side of the railway carriage by a simple winch or, for example, a hydraulically operated support member located in the vehicle, without the need to lift it from the vehicle. Tank transfer loading iron. : it must be possible to travel from the road carriage in the same simple way to the 1 step vehicle arriving at the receiving station. The apparatus according to the invention, which enables such simple cargo handling, is characterized in that the apparatus comprises at least one locking piston mounted on the carriage, at least one rod connected to the locking piston movable transversely to the longitudinal direction of the carriage against the action of a spring member, located at the rear of a vehicle equipped with a removable and rail-mounted load carrier and enabling the bar to move the locking piston to the neutral position by pressing the bar in the vehicle while the vehicle is driven against the carriage to move the load carrier, and the spring member is arranged to press when the vehicle stops moving away from the wagon to bring the locking piston longitudinally of the wagon to the position where the locking piston secures the load carrier to the wagon.

Other features of the invention will become apparent from the following and accompanying drawings, in which

Fig. 7 shows on a larger scale a vertical section taken along the line VII-VII in Fig. 5.

Fig. 8 shows a plan view of the locking device of the railway carriage in the locking position and

Fig. 9 similarly shows the locking device in the free position.

Fig. 10 shows a top view of a locking device according to another embodiment, this being in the locking position, and

Fig. 11 shows it in the free position.

The truck shown in Fig. 1 has a liftable and lowerable cargo frame, by means of which the container 3 can be raised from the lower position, i.e. the transport position, to the upper position for transfer loading. The rear end of the cargo frame 2 is provided with an end plate 4. The lower part of the container is provided with longitudinal guide beams 5, each of which is provided with 1 and 6 through-openings 7 for a locking piston 8.

The support platform 9 of the railway carriage 10 for the simultaneous transport of three containers 3 is provided with a set of locking devices 11, 12 and 13, each of which is provided with a locking piston 11. According to the embodiment shown in Figures 5, 8 and 9, the locking device includes a vertical an arm cross 15 rotatable about a bolt 14 provided with four arms 16, 17, 18 and 19. Each arm 16 and 18 is connected by means of its own connecting part 20 and 21 from its joints flexibly to its locking piston 8 arranged to move longitudinally in the guide 22 of the railway carriage 10. Each the arms 17 and 19 are connected by a connecting part 23 and 24 respectively to the joints flexibly to their own handlebar 25 4 74660 and 26, which are movable in the transverse guides 27, 28 of the carriage 10. A coil is tightened between the guide 28 and the sleeve 30 near the outer end of the rod 25 a spring 31, 32 which tends to hold the arm cross 15 in the position shown in Figure 8, wherein the locking pistons 8 are in the locking position, i.e. placed in the openings 7 in the guide beams 5 and in the opening 33 in the transverse support beams 34 of the railway carriage 10.

When the truck 1 with the load frame 2 and the container on top is raised towards the other side 35 of the railway carriage (Figs. 5 and 8) in front of one of the locking devices 11, 12 or 13, the end plate 4 protrudes against the free end 29 of the handlebar 25. In this case, this rod 25 presses against the action of the spring 31 in the direction of the arm cross 15, which rotates clockwise via the connecting part 23 as shown in the figure. As a result, the locking pistons 8 move towards each other to the free position, shown in solid lines in Fig. 7. The container 3 can now be moved to a suitable transport position on the carriage by sliding it on the guide beams 5 by the local support beams 34 of the railway carriage 10. When the truck 1 is then driven off (or the load frame 2 is turned down to the initial position - Fig. 1), the pressure against the rod end 29 ceases, and the spring 31 moves the rod 25 back to its outer position (starting position) by turning the arm cross 15 counterclockwise and moving the locking pistons 8 to is shown by dotted lines in Fig. 7. The container 3 is now locked to the railway carriage 10, which locking position can be directly detected from the outside so that the ends 2¾ of the bars are moved to their external position, just outside the side edge 35 of the railway carriage 10.

Figures 10 and 11 show a modification form of the locking device. Here, both guide rods 25 'and 26' are formed as a single piece with the center-mounted backrest guide 36. This is provided with an arcuate groove 37 for its lock support piston 8 ', which is axially displaceable in the guides 38 in the railway carriage 10 and which engages the groove 37 via a bolt 39.

Il 5 74660

When the end plate 4 pushes the rod end 29 'inwards, the stage guide 36 moves against the action of the spring 31' to the side position shown in Fig. 11, where the arcuate edge 40 of the groove 37 presses against the bolt 39 and moves the locking piston 8 'to the free position (Fig. 11). As soon as the pressure towards the rod end 29 'ceases, the spring 31' forces the urinal guide 36 back to its initial position, where the locking piston 8 'is in the locking position (Fig. 10).

The embodiments shown and described are intended to be illustrative only, and the locking devices 11, 12, 13 can be structurally modified in many different ways within the scope of the claims set out below. Namely, other types of behind-the-scenes controls 36 are also possible. The only thing that is essential is that when the handlebar is pushed inwards at one end by one of the pressing parts 11a on the vehicle reversing the other side of the railway carriage, the locking pistons are brought into the free position so that when the vehicle leaves and the pressure against the end of the rod ceases. to a position where the 1a bracket becomes locked to the railway carriage.

When reversing the vehicle towards the railway carriage, the compressive force does not necessarily have to be applied directly against the rod end 29. Instead, the end of the rod may be connected by an articulated lever arm which is rotatably mounted at one end on the long side of the railway carriage and the other end of which comes freely outside the side of the carriage. This free end should have a lower surface running obliquely downwards towards the side of the wagon. One advantage of such an embodiment is that the locking pistons 8 can also be brought into the free position if the lifting frame (load frame 2) hits its side plate 4 below the free end of the lever arm. level in which it is achieved. · The inward movement of the rod 25 and consequently the 6 -. . 1 74660 Disposal of locking pistons in neutral position. The locking pistons are then moved to the locking position by the action of the resilient member when the pressure against the end of the lever arm ceases.

As described above and shown in the drawings, each locking device is provided with two locking pistons, but locking devices with only one locking piston can also be considered.
