Railway wagon for transportation of semi-trailers and the like

Abstract

A railway wagon for semitrailers and the like has a first bogie, a second bogie and a carrying section therebetween. An elongated channel configured to receive conduits for air, hydraulics and/or electronics extends between the two bogies. The media channel is lowered in a mechanical way when the carrying section is turned out to a loading/unloading position.

1 . A railway wagon configured to carry a semitrailer or the like, said railway wagon comprising a first bogie, a second bogie and a carrying section; said carrying section being movable between a first position in which it extends between said bogies, and a second position in which the carrying section is turned out from the railway wagon for loading and unloading of a semitrailer; wherein said railway wagon comprises a beam assembly configured to be moved out from and back to the railway wagon and to support a front portion of the carrying section; wherein the beam assembly comprises a leg which is arranged at an outer end of the beam assembly and which is configured to support against the ground; and wherein the beam assembly further comprises an actuator which is configured to lower and raise the leg and which is arranged substantially in parallel with a main extension of the beam assembly. 
     
     
         2 . The railway wagon as claimed in  claim 1 , wherein said actuator comprises a hydraulic cylinder. 
     
     
         3 . The railway wagon as claimed in  claim 1 , wherein said leg has a foot at its free end, said foot being configured to abut the ground. 
     
     
         4 . The railway wagon as claimed in  claim 1 , wherein the actuator is connected to the leg at a first pivot at a first end of the leg. 
     
     
         5 . The railway wagon as claimed in  claim 3 , wherein the foot is connected to the leg at a second pivot at a second end of the leg. 
     
     
         6 . The railway wagon as claimed in  claim 5 , wherein a link is connected between said outer end of the beam assembly and the leg, and wherein the link is connected to the leg at a point at a distance from the first and second ends of the leg. 
     
     
         7 . The railway wagon as claimed in  claim 6 , wherein the link is connected to the beam assembly at a third pivot and to the leg at a fourth pivot. 
     
     
         8 . The railway wagon as claimed in  claim 7 , wherein the leg and the link form a scissor linkage able to take up forces in several directions. 
     
     
         9 . The railway wagon as claimed in  claim 1 , wherein the first end of the leg is placed at a sliding member which is moveable along a rail mounted substantially in parallel with said main extension of the beam assembly. 
     
     
         10 . The railway wagon as claimed in  claim 2 , wherein the leg—when a piston of the hydraulic cylinder is fully retracted—has a horizontal position, in which the beam assembly represents a compact unit. 
     
     
         11 . The railway wagon as claimed in  claim 3 , wherein a force or pressure sensing device is arranged in connection with the foot of the beam assembly leg. 
     
     
         12 . The railway wagon as claimed in  claim 11 , wherein said force or pressure sensing device comprises a sensor configured to send signals to control systems ensuring that correct pressure or load is put on the foot and thereby on the leg and the entire beam assembly. 
     
     
         13 . The railway wagon as claimed in  claim 11 , wherein said sensing device is configured to sense when the foot gets into contact with the ground and to send signals to the actuator which controls the movements of the foot. 
     
     
         14 . The railway wagon as claimed in  claim 1 , wherein the beam assembly during its movement—from an idle position in parallel with the railway wagon to an active position turned out from the railway wagon in a direction transverse to the same—is configured to guide said front portion of the carrying section. 
     
     
         15 . The railway wagon as claimed in  claim 1 , further comprising means for lowering and raising the front portion of the carrying section.
