摘要:
Locking device for crossings with movable frog point, including a cradle support with a central recess into which a movable frog point with transverse displacement in order to place thereof in two steady end positions is housed; characterized in that it comprises a pair of side left (10) and right (11) boxes, a transverse slide (9) through central part of which is connected to a movable frog point (8) being coupled in said side boxes (10-11), a widger (14) axial displacement of which carries the transverse slide (9) being guided inside said transverse slide (9), the widger (14) further comprising some depressions (30) into which the bottom of the locking rollers (25) is housed during the relative displacement of the widger (14) with respect to the transverse slide (9) and also during the whole movement of both elements (9-14).

The invention comprises two bolt bodies (1, 2, 32, 33) linked by an intermediate bar (5, 37), and with one of them connected to an external actuating mechanism, arranged transversely to the railway and suspended from the respective shoe (6, 35) of the counterpoint (4, 36). The needles (3, 34) are moved by means of respective sliders (14, 43) which slide within a box (9, 39) fastened to the bolt bodies (1, 2, 32, 33). Bars (15, 38) slide in each of the sliders (14, 43) and the bars are lockable (15,38) with the sliders (14, 43) and the sliders (14, 43) with the boxes (9, 39). The bar (38) has two wide rabbets (48, 49) each for housing a roller (50, 51) which move in each of the transversal sheaves (52, 53) of the slider (43). These rollers (50, 51) interact with the semicylindrical rabbets (54, 55) of the box (39). The relative position of the rollers (50, 51) controls whether the slider (43) is dragged or not.
摘要:
The present invention relates to a tram crossing (100), comprising a fixed part (110) embedded in concrete comprising a hollowed-out central surface (130) suitable for receiving a composite central part (140, 150 160), and a bolting system (135, 145, 175) for fixing the composite central part (140, 150 160) to the hollowed-out central surface (130), wherein the embedded fixed part and the composite central part form rolling grooves (120a, 120b) for the passage of a tram, the crossing being characterized in that the composite central part (140, 150 160) comprises three disconnected elements, which are a right wing rail (160), a left wing rail (140), and a frog (150). The bolting system (135, 145, 175) allows fixing each of the disconnected elements (140, 150 160) to the hollowed-out central surface (130).

This is intended to be placed in an interrupted space of two rails turnout one another and that belong to two different tracks. It is characterised in that it includes in principle an immobilised support cradle (1) that has a central space (7) and several end rail sections (10-11) converging towards this central space (8) and aligned with the rails (3-4) of the turnout a transversally moveable movable point (8) being located in this central space (7) that can be placed stably in two end side positions to align using its side rolling portions (12) with one of the end rail sections (10 or 11), there also being several transversal guides (9) used to move and facilitate the movement of the movable point (8) to its end stable side positions.
