Embodiment Construction
[0024] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0025] figure 1 Shown is a sliding device 100 for a point switch of a railway switch according to the invention. The sliding device 100 comprises a rectangular base plate 1 with a region 30 for mounting a base rail 10 . Backer base plate 1 is also image 3 shown in . On both sides of the area 30 , on the upper surface of the backing plate bottom plate 1 are respectively provided an iron seat 11 for installing elastic bars 12 and a crimping platen 6 . The spring bars 12 and the crimping platen 6 are used to crimp both sides of the rail legs of the basic rail. The upper surface of the base plate 1 is also provided with guide holes 8 arranged in parallel with the crimping platen 6 . Guide hole 8 is a stepped struc...

The invention relates to a sliding device for a turnout railroad switch. The sliding device comprises a backing plate base plate and a sliding mechanism, wherein the backing plate base plate comprises an elastic strip and a buckling and a pressing bed plate for buckling and pressing a rail limb of a stock rail and a guide hole, and the sliding mechanism comprises a guide piece which can slide in the guide hole along the length direction and a sliding table which is fixedly connected with the guide piece. The sliding table can slide along with the guide piece to enable a tip rail supported by the sliding table to slide along with the sliding bed. A sliding direction of the tip rail is the direction which the tip rail comes close to or is far away from the stock rail. A first antifriction sheet and a second antifriction sheet are arranged between the contact face of the guiding piece and the backing plate base plate and the contact face of the sliding bed and the backing plate base plate, accordingly frictional resistance of motion is reduced, reduction of frictional resistance and insufficient displacement caused when the tip rail comes close to or is far away from the stock rail is achieved, and traveling safety and passenger comfort are guaranteed.
Description
technical field [0001] The invention belongs to railway track components, in particular to a sliding device for a turnout switch. Background technique [0002] In railway track components, the point switch of the turnout guides the rolling stock to travel along the main line or side line through the swing of the switch rail. The sliding bed board is a backing plate with a sliding bed platform, and when the whole switch rail swings, it buckles the basic rail within its length and provides a support platform for the swing of the switch rail. [0003] During the swinging process of the switch rail, friction will be generated when the switch rail slides on the slide table. Therefore, the frictional resistance will hinder the swing of the switch rail and cause a certain elastic deformation of the switch rail, so that it cannot reach the ideal position. There is a certain distance between the actual reachable position and the ideal position without frictional resistance. This d...
