Device for moving a tongue rail of a gate

Abstract

A device for moving a tongue rail of a switch is provided, the device having a retaining element attached to a stock rail and at least one roller fastened thereon, the axis of rotation of which roller is substantially parallel to the rail course, and which is arranged in such a way that the tongue rail can roll up from a lower contact position on the stock rail onto the roller to a remote position, and having a spring element arranged in the interior of the roller and fastened by at least one screw connection fixed adjustably to a slide rail on the retaining element.

1 . A device for moving a tongue rail of a switch, the device comprising

         2 . The device according to  claim 1 , characterized in that an outermost shell of the at least one roller is metal. 
     
     
         3 . The device according to  claim 1 , characterized in that the at least one roller is an elastomer-sprung roller. 
     
     
         4 . The device according to  claim 1 , characterized in that the at least one roller is attached to the retaining element by at least one eccentric fastening. 
     
     
         5 . The device according to  claim 4 , characterized in that the eccentric fastening includes at least one polygonal plate fixed in the slide rail on the retaining element, and at least one shaft configured and arranged to extend through the plate via an acentric bore. 
     
     
         6 . The device according to  claim 1 , characterized in that a second roller of the at least one roller is fastened to the retaining element, wherein an axes of rotation of the first and second rollers are arranged substantially parallel to one another. 
     
     
         7 . The device according to  claim 1 , characterized in that a bearing of the at least one roller is integral to the retaining element. 
     
     
         8 . The device according to  claim 1 , characterized in that the spring element is a hollow cylinder with an inner diameter in a range between 30% and 60% of the outer diameter. 
     
     
         9 . The device of  claim 2 , characterized in that the roller is designed as an elastomer-sprung roller. 
     
     
         10 . The device of  claim 3 , characterized in that the roller is attached to the retaining element by at least one eccentric fastening 
     
     
         11 . The device of  claim 5 , characterized in that a second roller of the at least one roller is fastened to the retaining element, and wherein an axes of rotation of the first and second rollers are arranged substantially parallel to one another. 
     
     
         12 . The device of  claim 6 , characterized in that a bearing of the at least one roller is integral to the retaining element. 
     
     
         13 . The device of  claim 7 , characterized in that the spring element is a hollow cylinder with an inner diameter is in a range between 30% and 60% of the outer diameter. 
     
     
         14 . The device of  claim 13 , wherein the inner diameter of the spring element is in a range between 45% and 55% of the outer diameter. 
     
     
         15 . The device of  claim 8 , wherein the inner diameter of the spring element is in a range between 45% and 55% of the outer diameter.
