Railway wagon with improved launch beam mounting

Abstract

A railway wagon for transportation of semi-trailers has a first wagon end, a second wagon end, and a carrying section with a front portion releasably connected to the first wagon end. The carrying section is movable between a closed position and an open position. The first wagon end has a rail support beam movable in a vertical direction and for abutment on a railway track for support and positioning during movement of the front portion. A beam assembly configured to support the front portion while being turned, is pivotally connected to the rail support beam. An actuator between the first wagon end and the beam assembly is configured to move the beam assembly between an inoperative position and an operative position. A displacement device is provided at the actuator.

1 . A railway wagon for transportation of at least one vehicle, comprising: a first wagon end, a second wagon end and a carrying section therebetween; the carrying section having a front portion releasably connected to the first wagon end, the carrying section being movable between a closed position in which the front portion is connected to the first wagon end, and an open position in which the front portion is turned out from the first wagon end for loading and unloading of said at least one vehicle; wherein the first wagon end comprises a rail support beam movable in a vertical direction, the rail support beam being configured to be lowered onto a railway track for supporting and positioning of the first wagon end during movement of the front portion between the closed position and the open position; wherein the railway wagon further comprises a beam assembly configured to support the front portion while the front portion is being turned, the beam assembly having a first end and a second end, the first end being pivotally connected to at least the rail support beam; and an actuator arranged between the first wagon end and the beam assembly for moving the beam assembly between an inoperative position and an operative position and vice versa; and wherein a displacement device is provided in connection with the actuator. 
     
     
         2 . The railway wagon according to  claim 1 , wherein the actuator comprises a hydraulic cylinder. 
     
     
         3 . The railway wagon according to  claim 1 , wherein the actuator has a predetermined length. 
     
     
         4 . The railway wagon according to  claim 1 , wherein the actuator has a first actuator end and a second actuator end, the first actuator end being connected to the first wagon end and the second actuator end being connected to the beam assembly. 
     
     
         5 . The railway wagon according to  claim 1 , wherein the displacement device is arranged at the first actuator end and/or at the second actuator end. 
     
     
         6 . The railway wagon according to  claim 1 , wherein the displacement device is provided in the actuator or along an extension of the actuator. 
     
     
         7 . The railway wagon according to  claim 1 , wherein the displacement device comprises an elastic element, preferably a biasing spring, such as a coil spring or a compression spring. 
     
     
         8 . The railway wagon according to  claim 4 , wherein the first actuator end is connected to the first wagon end via a first attachment pin and the second actuator end is connected to the beam assembly via a second attachment pin. 
     
     
         9 . The railway wagon according to  claim 8 , wherein the displacement device comprises one or more spring-loaded pin(s) arranged on an opposite side of the attachment pin in relation to the actuator end. 
     
     
         10 . The railway wagon according to  claim 9 , wherein the spring-loaded pin(s) is/are connected to the actuator. 
     
     
         11 . The railway wagon according to  claim 1 , wherein the rail support beam is connected to an actuating assembly, preferably a hydraulic cylinder, configured to move the rail support beam downwards and/or upwards. 
     
     
         12 . The railway wagon according to  claim 11 , wherein the actuating assembly is connected to the first wagon end via an attachment plate, the attachment plate having a first connection point pivotally connecting the attachment plate to the first wagon end, and a second connection point connecting the attachment plate to the actuating device, the first connection point and the second connection point being offset in a vertical plane.
