Description

Technical field

The present invention relates to a railway wagon for transporting semi-trailers and the like.

State of the art

Railway wagons are widely used to ensure the loading and transportation of semi-trailers. Placing a semi-trailer designed for road transport on a rail car provides more efficient and environmentally friendly transportation compared to road transport. As a rule, rail transportation is used as an option

when transporting over long distances. Examples of railway wagons for transporting semi-trailers are given in WO 2010/120236 A1.

Loading and unloading of the semi-trailer in the system of railway cars of this type occurs due to the rotation and return to the initial position of the load-carrying part of the railway car. To facilitate the rotation of the load-carrying section, a beam is usually used, which can be pulled out of the railroad car. At the outer end of the beam, a ground support is provided, which is often in the form of a telescoping support member. The leg is moved by a vertically operated jack capable of lowering the leg until it hits the ground, which will support the beam as the load-bearing section pivots away from the rail car or vice versa. Although such a vertically operated jack will provide proper operation throughout, there is a risk that it may break. Jack failure can occur if the structure is subjected to movements that can occur when the load from the ground support is not vertical; for example, if the support is located on uneven ground.

The composition of the existing railway cars of the above type includes a lot of cables and pipelines passing along its platform. During the rotation of the carrier section, there is a risk that these cables and pipes may get stuck or damaged.

It follows from the above that there is room for improvement in rail car systems.

Disclosure of the essence of the invention

The purpose of the present invention is to solve or at least mitigate the problems associated with already existing designs. This goal was achieved using the equipment described in the attached independent claim 1; preferred embodiments of the invention are defined in the respective dependent claims.

In one aspect, the invention relates to a rail car capable of carrying a semi-trailer or the like. The railway car contains the first bogie, the second bogie and the carrier section between them. The carrier section is movable between a first position, in which it passes between two bogies, and a second position, in which the carrier section is turned away from the railway car for loading and unloading the semi-trailer. The railroad car further comprises a piping channel extending between the first and second bogies. The channel is made with the possibility of automatic mechanical lowering when the carrier section is rotated to the second position. The advantage of this railway car design is that various kinds of pipelines, namely air supply pipes, hydraulic oil supply pipes, and power cables, can be safely housed in one channel, which is also called a media channel. Pipelines are placed in the media channel and are protected during rail transport and during loading and unloading of semi-trailers when the carrier section rotates and returns to its original position in relation to the rail car.

This channel is preferably located under the carrier section, whereby its rotary movement can be carried out in a safe manner.

In an embodiment of the invention, one end portion of the channel is movable on a rod having an inclined portion. Preferably, the channel contains a roller mounted on a rod. The above functions ensure the safe operation of the media channel.

In another aspect, a railroad car beam assembly is provided that is movable from the railroad car and back to a home position. The beam assembly may include an actuator, preferably a hydraulic cylinder, configured to lower and raise a leg located at the outer or outer end of the beam assembly. It is desirable that there is a support at the free end of the leg. The drive is preferably located parallel to the main projecting part of the beam assembly. Due to this design of the beams, loads that are not completely vertical can be taken up. In addition, the risk of breakage of the hydraulic cylinder is reduced.

The improved beam assembly is adapted to be mounted on a railroad car which is configured to carry semi-trailers and the like and has a first bogie, a second bogie and a carrier section therebetween. When a semi-trailer needs to be loaded onto a railcar, the beam assembly is moved out of the railcar into an active position in which it guides the front of the outward-turning carrier section into the loading position. The beam assembly is moved back to the wagon and the semi-trailer is moved onto the lowered inclined carrier section, which is raised after loading. The beam assembly then extends again and guides the front of the raised carrier section (with the semi-trailer on it) back into the car position. Finally, the beam assembly is moved back to the car, which is now ready for rail transport.

Also the subject of the present invention is a railway car of the above type, which is equipped with an improved beam assembly according to the above aspect.

The beam assembly may have hinges and links that serve to provide reliable ground support for the beam in its active position extended from the car. This system of hinges and links is located at the free end of the beam assembly and is connected to the beam leg, and is also movable.

The railway car may have a kingpin blocking slider, the mobility of which is ensured by two cylinders. The two cylinders are connected to the reservoir via a spring loaded valve to act as dampers.

Other objects and advantages of the present invention and related embodiments will become apparent from the following detailed description.

Implementation of the invention

On the example of Fig. 1 and 2 show a rail car 1 capable of loading a semi-trailer 2. The rail car 1 includes a first bogie 3 and a second bogie 4 located at opposite ends of a load-bearing section 5. As shown in FIG. 1, the carrier section 5 can be rotated outward and lowered so as to allow the semi-trailer 2 to be loaded onto said part 5. The carrier section 5 is hinged to the second bogie 4 by pivoting means (not shown) which allow the part 5 to be rotated or rotated. to the position shown in Fig. 1. When the semi-trailer 2 enters the carrying section 5, this part 5 rises and turns back, together with the semi-trailer 2 loaded on it, into the position shown in FIG. 2.

To rotate the carrier section 5 in and out of the first bogie 3 of the railway car 1, a beam 6 is extended. The beam 6 rests on a telescopic leg 7, made in the form of a hydraulic cylinder, at the outer end. The hydraulic cylinder is installed and works in the vertical direction. After the carrier section 5 has been rotated, the beam 6 is moved back to the first bogie 3 so that the semi-trailer 2 can be loaded onto the carrier section 5. The beam 6 is then pushed back again to rotate the load-carrying section 5 back to match the first and second bogies. 3, 4. In the position in which the carrier section 5 is turned outward, it lowers to allow the semi-trailer 2 to be loaded, and then rises again when it needs to be returned to its original position. The railway car 1 is equipped with means (not shown) for lowering and raising the front part 1a of the carrier section 5.

In the following, the position shown in Fig. 2 is also called the first or transport position, and the position shown in FIG. 1 is called the second position for loading or unloading the semi-trailer 2 or the like. In the second position shown in Fig. 1, the carrier section 5 serves as a ramp for the semi-trailer 2, which is to be rolled onto the carrier section 5 for transportation by the rail car 1 or lowered from the carrier section 5 upon reaching the destination.

In FIG. 3 and 4 show a railway car 1' having the same basic structure as the railway car 1 in FIG. 1-2, but already equipped with a modified beam assembly 8 movable from and into the first carriage 3 when the carrier section 5 needs to be rotated outward or returned to its original position. The modified beam assembly 8 is mounted on the railway car 1' and preferably includes a hydraulic cylinder 9 which runs parallel to the axis of the beam. With this placement of the hydraulic cylinder 9, this cylinder is parallel to the main protruding part of the node 8 of the beam.

With reference to FIG. 5-7 shows that the outer end of the piston of the hydraulic cylinder 9 is connected to the first end of the leg 10. The support 11 is placed on the second end of the leg 10. The hydraulic cylinder 9 is connected to the leg 10 through the first hinge 12, and the support 11 is connected to the leg 10 through the second hinge 13. Between the beam body and the leg 10 is a link 14. As shown, the link 14 is connected to the outer end of the beam node 8 by a third hinge 15 and to the leg 10 by a fourth hinge 16. The link 14 is connected to the leg 10 at a position between the first and second ends legs 10.

The end of the leg 10 on the hydraulic cylinder 9 is placed on the slider 8A, which is connected to the guide 8B mounted on the node 8 of the beam. The slider 8A moves freely along the guide 8B and thus along the beam assembly 8. However, the slider 8A cannot move freely in the vertical direction, and thus the hydraulic cylinder 9 is kept parallel to the main projection of the beam assembly 8.

In the embodiment shown, leg 10 is made of two parallel plates. However, one skilled in the art will appreciate that leg 10 may be of various designs.

When the hydraulic cylinder piston 9 is fully retracted, the leg 10 is in a horizontal position on the beam assembly 8 as shown in FIG. 5. In this non-operating position, the beam assembly 8 is a compact unit with no parts protruding downward from the beam body. The movement of the node 8 of the beam between the idle position in the car 1' and the active position across the car 1' is an advantage.

To lower the leg 10 into the active position of the node 8 of the beam, the piston of the hydraulic cylinder 9 is pushed out. The leg will be rotated down due to the link 14 located between the beam body and the leg 10. The leg 10 will be lowered until the support 11 touches the ground G, as shown in Fig.6 (see also Fig. 3-4). The support 11 can also be securely installed on sloping ground, since the support 11 is attached to the leg 10 by means of a second hinge 13,

Leg 10 and link 14 form a kind of scissor joint that can take forces in several directions. Since the hydraulic cylinder 9 is located horizontally on the beam node 8, it has a well-defined position and working area, so it will not be subject to any skew forces, regardless of the direction of the forces on the support 11 from the ground G.

The operation of the railway car 1' equipped with the improved beam assembly 8 can be briefly described as follows. When the semi-trailer 2 is loaded onto the railway car 1', the beam unit 8 moves from the car 1' to an active position in which it guides the front part 1a of the carrier section 5 pivoting outward into its loading position. The beam unit 8 moves back to the car D, and the semi-trailer 2 moves to the lowered inclined carrier section 5, which rises after loading. The beam assembly 8 then extends again into a position transverse to the longitudinal axis of the car 1' and guides the front part 1a of the raised load-bearing section 5 (with the semi-trailer on it) back into the position of the car. Finally, the beam assembly 8 moves back into the car, which is ready for rail transport. The railway car 1 is equipped with means (not shown) for lowering and raising the front part 1a of the carrier section 5.

Railway car 1' in FIG. 8-9 includes hydraulic, air and electronic piping (not shown) extending from the first bogie 3 to the second bogie 4 at opposite ends of the railcar 1'. An elongated channel 17 is provided for these conduits. Thus, the conduits are securely held together in the conduit 17. As shown in FIG. 8, the channel 17 extends between the first car 3 and the second car 4. One end of the channel 17 is pivotally connected to the second car 4 by means of an articulated means (not shown). When turning the carrier section 5 away from the wagon 1', the channel 17 must be lowered when the carrier section 5 is lowered for loading and unloading the semi-trailer 2.

As shown in FIG. 9, the channel 17, which is also referred to as the media channel for accommodating conduits, is supported by a rod 18 near the second truck 4. The channel 17 has a roller 17A adapted to follow the rod 18. In addition, the rod 18 has an inclined portion 19 located in the highest point of the position when the carrier section 5 is turned back towards the railway car 1'. When the carrier section 5 is turned away from the railway car 1', the roller 17A of the channel 17 will go down the inclined guide portion 19, thereby lowering the channel 17. In this way, the media channel 17 is mechanically lowered, eliminating the need for any hydraulic cylinder or similar means for lowering and making movements more precise as channel 17 automatically lowers.

The railway car 1' shown in FIG. 10-12 includes a semi-trailer 2 kingpin locking system when the semi-trailer 2 is on the railcar 1'. This system includes a slider 20 which is movable to grip a king pin (not shown). The slider 20 moves back and forth longitudinally along the central axis of the car by means of two hydraulic cylinders 20 A. When the semi-trailer 2 is loaded onto the rail car 1' and the train is moving, the cylinders 20A act as dampers in case the rail car 1' experiences any shocks. , for example, if the train cars collide with each other.

This damping effect is achieved by providing a reservoir (not shown) for the oil of the cylinders 21 and a spring-loaded valve (not shown) which, at a certain predetermined pressure, passes the oil from the cylinders 21 into the reservoir. When the cylinders 21 have moved a certain distance, for example 50 mm, the reservoir will be full and the cylinders 21 will not move any further. Before reaching the end position, a certain degree of damping takes place.

A slightly modified version of the beam assembly 8 is shown in FIG. 13-19. Reference symbols are the same as in FIG. 3-7 are also used in FIG. 13-19. In order to obtain a suitable pressure or load on the support 11 of the leg 10 of the beam assembly, a sensor for measuring force or pressure is installed in connection with the support 11. This sensor includes an actuator 22, 23 having an upper portion 22 which engages the hinge 13 of the leg 11 and a lower portion 23 protruding downwardly from the upper portion 22. As best seen in FIG. 15, a series of annular belleville springs 25 surround the lower part 22 of the actuator 22, 23. The belleville springs 25 may be so-called Belleville washers. The downward projection 23 is positioned directly above the opening 24 in the bottom plate of the support 11. As best seen in FIG. 17-19, there is a sensor 26 located in connection with the actuating element 22, 23 of the support 11.

When the leg 10 of the beam unit 8 is lowered against the ground G, the axle 13 is pressed against the upper part 22 of the actuator 22, 23, which means that the downwardly protruding part 23 is inserted into the hole 24 under the action of the Belleville springs 25. This movement is detected by the sensor 26, which is configured to send signals to control systems (not shown) to provide the correct pressure, or load, to the support 11, and thus also to the leg 10, as well as to the entire beam assembly 8. As the leg 11 is lowered towards the ground G, a sensor 22-26 detects when the leg 11 is in contact with the ground G and can send signals to an actuating cylinder 9 which controls the movements of the leg 11 via the link, leg and pivot assembly 10-16. Thus, a smooth and safe abutment of the support 11 against the ground G is achieved, which ensures the safe operation of the beam assembly 8.
