Embodiment approach

[0132] According to Figure 7 In an alternative exemplary embodiment schematically shown in , the first frame 160a supporting the first switch switch rail 141 and the second switch switch rail 142 may have a smaller and more compact design and be supported by a plurality of sleepers 304a.

[0133] Similarly, so external Figure 7As shown in an alternative exemplary embodiment of the switch frog 150, the second frame 160b of the first vertically displaceable rail section 144 and the second vertically displaceable rail section 143 of the switch frog 150 may have a smaller And more compact design and supported by multiple sleepers 304b. The sleepers 304a, 304b may be conventional sleepers such as, for example, made of wood or concrete.

[0134] The small format first frame 160a and second frame 160b may have relatively thin side walls, such as in the range of 10-200 mm, specifically in the range of 20-150 mm, and more specifically 25-100 mm. mm. The first frame 160a and the s...

Abstract

The disclosure concerns a railway switch mechanism (100) comprising a first and a second switch blade (141; 142), wherein a switch point (145a; 146a) of each of the first and the second switch blade (141; 142) is vertically displaceable by means of a displacement mechanism (200a; 201a) in order to establish a switch movement in the respective switch point (145a; 146a), wherein the respective displacement mechanism (200a; 201a) comprises at least one pair of cooperating wedges (311 a, 312a, 313a, 314a, 315a, 311 b, 312b, 340a, 341a, 342a, 343a) having a lower wedge (211a, 211b) and an upper wedge (212a, 212b), wherein at least one wedge of the at least one pair of cooperating wedges (311a, 312a, 313a, 314a, 315a, 311 b, 312b, 340a, 341a, 342a, 343a) is arranged to be displaced in a direction substantially parallel to a longitudinal direction of the switch blade (141, 142) or parallel with a longitudinal direction (L) of the switch mechanism, and wherein the switch blades (141; 142) areelastically deformable in the vertical direction or pivotally connected by hinged joints to first and second closure rails (170, 171 ) respectively for enabling the vertical displacement of the switchblades (141; 142). The disclosure also concerns a corresponding switch frog, an assembly of such a switch blade switch mechanism and switch frog, and a method for operating such an assembly.

Description

technical field [0001] The present disclosure relates to a track switch mechanism, which includes a first switch switch rail, a second switch switch rail and a switch frog. The present disclosure also relates to a method for operating a track switch mechanism having a first switch switch rail and a second switch switch rail and a switch frog, a track switch mechanism including a switch frog, and a track switch mechanism including a first switch switch. The track switch mechanism of switch point rail and second switch point rail. Track switch mechanisms may generally be used to enable switching from along a main track route or from a branch track route, or vice versa. Background technique [0002] It is well known that track switches have reliability problems when operating in winter conditions as snow and ice prevent correct switching of the switch switches. Snow and ice may prevent proper switch movement of the switch switches so that track service personnel may have to c...
