Abstract

The subject of this invention is an apparatus in transport equipment, especially for goods or similar in a railroad car to lessen the forces caused by the transport equipment collision. Between the transport equipment body part (1) and freight transportation platform (2) there are devices (3, 4, 5) enabling the transport platform (2) to be moved in relation to the body (1) in such a way that when the transport equipment collides with an obstacle, the movement of the transport platform (2) is parallel to the transport equipment movement and also vertical in relation to the body (1).<IMAGE>

Device in means of transport - Anordning i ett transportmedel

The invention relates to a device for reducing the forces exerted on a means of transport, in particular on goods in a railway carriage or the like, in the event of a collision of the means of transport.

When moving railway wagons at yards, there are often collisions at low speeds which do not in themselves cause any damage to the railway wagons themselves, but instead the goods carried in the wagons may be damaged by the collision.

The object of the invention is to provide a device which prevents or at least substantially reduces the damage caused to the goods to be transported in connection with such minor collisions of various means of transport.

According to the invention, this object is solved in that means are arranged between the transport body body and the goods transport platform for moving the transport base relative to the body part so that the collision of the transport means with the obstacle causes the goods transport movement to continue in the direction of movement and upwards relative to the body.

In this case, a longer distance is available for stopping the goods transport platform and the goods attached to it, during which the kinetic energy is converted into other forms of energy.

According to a preferred embodiment of the invention, the members are formed in pairs of suspension members arranged on opposite sides of the central axis of the body part, which are pivotally mounted at their upper end relative to a transverse axis connected to the upper part of the body part and transversely to a transverse axis connected to the transport base.

According to a preferred embodiment, the fastening points of the two adjacent suspension members on one side of the transport means are arranged so as to form the apex points of the parallelogram. In the event of a collision, the transport platform then rises in the same direction. Alternatively, it can also be arranged that the points of attachment of the suspension members on one side of the transport means form the apex points of the trapezoid. This provides a structure in which the leading edge of the base rises and the trailing edge falls in the event of a collision, while the entire base moves forward.

In yet another embodiment, it is advantageously provided that damping means are provided for damping the mutual movement of the transport base and the body part.

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

Figure 1 schematically shows a device according to the invention.

Fig. 2 shows a section along the line II-II in Fig. 1, however, the damper member has been omitted for the sake of clarity.

FIG. in the direction of movement of the means and at the same time upwards relative to the body part 1.

In the preferred embodiment shown in Fig. 1, said movement between the goods transport base 2 and the body part 1 is arranged as follows.

On the opposite side of the central axis of the body part 1 are arranged in pairs suspension means, indicated by reference numeral 3, preferably formed of plate-like pieces, pivotally mounted at its upper end with respect to a transverse axis 4 connected to the upper part of the body part 1 and downwardly 5 respect.

In the event of a collision, whereby the body part 1 stops, the transport platform 2 continues its movement, whereby it rotates around the shaft 4.

If the attachment points 4, 5 of the two adjacent suspension members 3 on one side of the transport means form the apex points of the trapezoid, the suspension members 3 can be provided in the required number and in the event of a collision the transport platform 2 rises with respect to the body part 1.

If desired, it can also be provided that the fastening points 4, 5 of the suspension members 3 on one side of the transport means form the apex points of the trapezoid.

If the distance between the lower attachment points 5 of the adjacent suspension members 3 is then greater than the distance between the upper attachment points 4, the front edge of the base 2 increases in the event of a collision and the rear edge of the base 2 decreases accordingly.

In order to slow down and dampen the movements between the body part 1 and the transport base 2, damping members denoted by reference numeral 6 in Fig. 1 are further provided, preferably formed by conventional hydraulic shock absorbers, one end fixed to the body part 1 and the other end to the lower end 3.

If necessary, locking means (not shown) can be provided to prevent mutual movement of the transport base 2 and the body part 1.

The invention has been described above with reference to only one preferred embodiment thereof. However, this is in no way intended to limit the invention to this example only, but many modifications are possible within the scope of the inventive idea defined by the following claims.
