EP1342636B1 - Front wall door with automated operating for a double deck railway wagon for the transport of motor vehicles - Google Patents

Abstract

The door (2a,2b) consists of two similar doors, is joined to a side wall (1) on one side at a corner pillar (15) and is operated about a vertical axis by a linear control element (4) mounted on the carriage structure on one side and interacting with the inside of the door on the other side via a connecting arm (5) connected to a linkage (6) mounted on the corner pillar.

Description

The invention relates to an end door with automated door operation for a double-decker car transport rail car according to the preamble of claim 1.

In the DE 40 20 020 A1 a railway carriage for the transport of passenger cars is described. The railway carriage has essentially two side walls, two end walls, a barrel-shaped lifting roof and two loading levels for transporting the vehicles. In order to allow the entry of cars in the area between the two side walls on the respective loading level, the front side must be open. It therefore consists in the upper part of an upward visually aufzuschwenkenden end wall flap and in the lower part of a roller shutter, consisting of several door segments. This roller shutter is pulled under the upper loading level when opening, when it is in a horizontal position. In order to ensure sufficient space for movement when loading and unloading the upper loading level, the lifting roof must also be extended upwards. As means for moving the lifting roof, the front wall flap and the rolling door are electric motors, hydraulic cylinders, cables, etc. intended. Appropriately, the individual movements of the aforementioned elements are necessarily coupled together, so that a single control command triggers the necessary movement sequences.

The described construction of the end wall door and its operation is structurally complex and complicated. This results in a complex and laborious workflow when opening and closing the end wall.

The object of the invention is an end wall door with automated door operation for To create a railway carriage of the type mentioned, which is designed simpler and less complicated in construction and the operation.

According to the invention, this object is solved by the features of claim 1. Advantageous embodiments of the invention are described in more detail in the dependent claims.

With the solution according to the invention there are a number of advantages. The design of the front wall door in the design of a vertical swing door and the associated automated operating mechanism result in a simple and clear design. The opening and closing operation of the front door is safe and avoids previously common manual actions.

As can be seen from the drawings, the double-decker car transport railcar is designed as a covered goods wagon, consisting essentially of two side walls 1, a vehicle roof 3, an end wall door and a lower loading level 11 and an upper loading level 10.

The end wall door of an end face consists of two identical to the vertical central longitudinal plane of the railway car arranged end wall doors 2 with a vertical pivot axis. The end wall door 2 of one side consists, in a preferred embodiment, of two door leaves 2a and 2b connected to one another by a hinge 14, the inner door leaf 2a and the outer door leaf 2b. The inner door leaf 2a is articulated to a corner pillar 15 of the carriage structure in a hinge 16.

For actuating the door leaf 2a, a linear actuator 4 is provided, which is connected to its housing in a pivot point 12 on the side wall 1 articulated. The actuator 4 may be provided with a motor or hydraulic drive. The push rod of the actuator 4 is connected to a connecting arm 5, which is mounted at the other end in the vicinity of the hinge 16 on the inside of the door leaf 2 a in a pivot point 13. The connecting arm 5 is advantageously carried out twice cranked, so that it forms a slight S-shape seen from above.

At the corner column 15, a handlebar 6 is mounted, which is articulated with its free end on the connecting arm 5. The connection of the handlebar 6 should be such that when pivoting the door leaf 2a of the connecting arm 5 is pivoted about the corner column 15. It is advantageous that the connection in the first third of the Connection point push rod / connecting arm 5 takes place.

At the free end of the outer door leaf 2b a control rod 7 is connected in the articulation point 9, which is mounted with its other end on the carriage side in a bearing 8 on the carriage structure. With this control rod 7, the door 2 b is guided defined when pivoting the end wall door 2.

It is conceivable that the bearing 8 are arranged vertically displaceable in the door 2b on the height-variable top loading level 10 and the pivot point 9. The height adjustment is carried out by positive engagement of the bearing 8 with the upper deck level 10 with pivoted-in door leaf 2b, see Fig. 7.

Below is the sequence of movements when opening the end wall door 2 will be described.

When closed, the end wall door 2 is locked in a manner known per se with the carriage structure. To open the lock is released. The push rod of the actuator 4 is extended in the direction of the end wall door 2 and introduced via the connecting arm 5 of the opening operation of the inner door leaf 2a. The link 6 operatively connected to the link 6 describes a horizontal, circular movement, whereby the door leaf 2a is pivoted in the hinge 16 to the corner pillar 15. The push rod is extended until the desired position or the end position of the end wall door 2 is reached.

As a result of the hinge connection with the inner door leaf 2a of the outer door 2b is pivoted during the opening process and positively guided defined by the control rod 7.

In the end position of the open end wall door 2, a pivot angle of significantly more than 90 degrees is realized, wherein the outer door 2b occupies an acute angle to the inside of the inner door leaf 2a.

This opening degree allows unimpeded loading and unloading of the double-decker car transport wagon.

The closing process is initiated by retracting the push rod of the actuator 4.
