Description

Railroad basket vehicles for transporting semitrailers

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a railway basket car for transporting a semitrailer, and more particularly to a basket vehicle having an open surface portion between longitudinal side beams of the vehicle.

BACKGROUND OF THE INVENTION So-called railway basket vehicles with pockets are known, which are used to transport semitrailers in the linkage of roads and railways. Until now, basket vehicles with two types of pockets have been known.

The first of these was that the pocket was a fixed part of the basket vehicle, so that the trailer had to be lifted and then placed in the pocket. However, semitrailers and some types of trailers could not be lifted by cranes because the underframe system was not built for this purpose and could not bear the weight of the semitrailer and cargo at the same time.

The other type of railway basket vehicle is equipped with a pocket that can rotate around its axis. The pocket can be rotated to the side of the basket vehicle with one of the longitudinal side beams of the pocket. In this position, the trailer or semitrailer could be transported directly to the pocket.

The drawback of this type of railway basket vehicle, however, is that both the pocket itself and the hydropneumatic actuator are quite complex structures that are not technically common, requiring skilled technicians to load the cargo. In the end, considerable time was spent.

Therefore, the present invention is simple in structure, does not require a skilled technician at work, and also has an object to provide a rail basket vehicle that can lift and load the semi-trailer.

Accordingly, the present invention relates to a railway basket vehicle for carrying a semi-trailer, wherein a surface between longitudinal side beams of the basket vehicle is at least partially open, and a basket is formed between the longitudinal side beams. The surface is arranged inside the open part, the basket consists of a bottom part for carrying a semitrailer and two side walls, the side walls being a means for supporting the basket on a longitudinal side beam of the basket vehicle and a loading protrusion. lugs, and the support means and / or longitudinal side compensation include a stop and a positioning member.

The pocket is lifted from the basket vehicle and the truck pushes the semitrailer over the pocket placed on the ground. The semitrailer wheels are then fixed to prevent rotation and the semitrailer is disengaged from the truck. The pocket and semitrailer are then lifted by the crane and placed in a railway basket vehicle.

According to a preferred embodiment, at least on one side of the basket, a transverse stop beam is located between the side beams, which basket also has a rear edge. The support means may be an upper portion of the sidewall bent outward of the basket.

According to another embodiment, the support means is a lifting lugs themselves.

Another embodiment includes an extension on a basket sidewall supported by hooks fixed on a longitudinal side beam of the basket vehicle.

The basket vehicle according to the invention can carry a semitrailer that cannot be lifted by itself. Such trailers account for 90-95% of the semitrailers currently used in Europe.

On the other hand, the structure of the basket vehicle according to the present invention is extremely simple, and production, use, and maintenance are all generally acceptable on railroads in Europe.

Hereinafter, with reference to the accompanying drawings to describe the present invention in more detail.

In FIGS. 1 and 2, a railway basket vehicle 1 is shown. Between the longitudinal side beams 2, 3 there is a basket 4 consisting of two side walls 4a, a rear edge 4b and a bottom 4c. The side wall (4a) is provided with loading protrusions (5) for lifting the basket (4) by the crane, the basket (4) is a side stop 14 and the base of the rotation of the basket vehicle (1) 15) are arranged between. The stacking protrusions 5 of the basket 4 are positioned by stop pieces 7, 9 arranged between both sides of the stacking protrusions 5 on the longitudinal side beams 2, 3.

Details of the stacking protrusion 5 and the positioning and stopping member are shown in FIGS. 3 to 6.

According to the embodiment shown in FIG. 3, the stacking protrusion 5 is arranged on an extension 6 of the side wall 4a of the basket 4, the extension 6 being a longitudinal side beam ( 2) It is bent outward to fix the upper basket (4).

In Fig. 4, the loading protrusion 5 itself is a supporting means of the basket 4, which is located directly on the longitudinal side beams 2, and is positioned in the longitudinal direction by the stationary piece 9. The central position of the entire basket 4 is fixed by a positioning block 8 fixed on the longitudinal side beams 2.

In the embodiment of FIG. 5, the positioning pin 10a and the hole 10b of the loading protrusion 5 are used to stop and position the basket 4.

In another embodiment of FIG. 6, the longitudinal side beams 2 are provided with hooks 11 which support the extensions 12 of the side walls 4a of the basket 4. The positioning and stopping member is a guide plate 13 arranged on the side wall 4a of the basket 4.

An embodiment of the basket vehicle according to the present invention can be used as follows.

The basket 4 is lifted from the basket vehicle 1 by a crane and lowered until it reaches the ground as shown in Fig. 7 (a). The truck 16 with the semitrailer 17 retreats until the wheel of the semitrailer 17 reaches the rear edge 4a of the basket 4 as shown in FIG. 7 (a). In this position the semitrailer 17 is secured by the legs 18 and disengaged from the truck 16 as shown in FIG. 7 (b). Next, the hooked cable 19 is connected to the loading protrusion 5, and the basket 4 is lifted by the crane together with the semitrailer 17 (see FIG. 7 (c)). The basket 4 and semitrailer 17 are then lowered until the basket 4 is firmly seated in the opening of the basket vehicle 1 as shown in FIG. 7 (d).

The position of the semi-trailer 17 can be adjusted by rotating the rotation base 15 of the basket vehicle 1.

The series of processes shown in FIG. 7 shows that loading a semitrailer into a railway basket vehicle can be made quickly and simply in accordance with the present invention. Lifting and unloading is done by a common crane and the basket is automatically positioned by means of longitudinal side beams and stationary and positioning elements on the sidewalls of the basket.

The above embodiments are illustrative and do not limit the scope of the appended claims.
