摘要:
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.

The present invention relates to an acute common crossing with moveable point for railway turnouts, comprising a fixed element (2) and a moveable element (3), as well as wing rails (2D), heel blocks (4), distance blocks (5), slide plates (6) and ribbed heel base plates (7). The front part of the fixed element (2) comprises a moulded part (2A) made of austenitic manganese steel and a base plate (2B), located below the moulded part, made of a steel with a greater fatigue resistance than the austenitic manganese steel of the moulded part (2A), for example, carbon steel or low alloy steel. The base plate (2B) is continuous and extends at least the entire length of the moulded part (2A), and the moulded part (2A) and the base plate (2B) are fixed to one another.

The invention relates to a rolling device (6, 7) for a displaceable cross frog (1), comprising a sliding strip (18), at least one roller (11), and at least one roller bearing (12) which is fixed to a fixed part of the points. The at least one roller (11) is mounted on an arm (9) of a two-armed lever (10). The pivoting bearing (12) of said lever (10) is arranged in a carrier (13) which is connected to a fixed part of the points. The arm (18) of the two-armed lever (10) which opposes the roller(s) (11) can be pivoted against a spring (19) with adjustable elastic force.

A railroad frog assembly is provided with a spring wing rail multi-position holdback subassembly (32) that continuously retains the spring wing rail (28) in each spring wing rail open position when activated by the wheels of a railcar traversing the frog assembly (20), and that automatically deactivates the multi-position holdback subassembly (32) and releases the spring wing rail (28) from retention in an open condition and for complete closing after the last railcar wheel has passed through the frog assembly (20).
摘要:
Acute crossing of tongue forming railway apparatuses which can be incorporated to a continuous ribbon-rail, comprising a fixed element and a moving element, the fixed element (1) being comprised of a first molded part (1A) made of cast manganese steel and of a second part made in rails (1B) formed preferably by the junction of two rails to said first molded part (1A), which are appropriate to act as anchoring elements for accessories such as buffers, buffer-blocks, ribbed plates and expansion joint (3), the movable element (2) being comprised of a mold part (2A) made of cast manganese steel and of two rail parts (2B, 2B') joined to the prior, one of said rail parts (2B) being coupled to said rail-in made part (1B) of said fixed element (1) by means of screwed buffer-blocks (4A, 4B, 4C), the other of the two rail parts (2B') being coupled to the expansion joint (3), thereby providing means for sliding said movable element (2) inside said fixed element (1), as well as means for coupling the movable element (2) to the right or to the left.
摘要:
La présente invention concerne un coeur de croisement à pointe mobile (1) pour appareils de voie ferrée de très grande longueur incorporés dans les longs rails soudés, ledit coeur de croisement comportant en outre notamment un berceau (2) en deux éléments (3 et 4), l'un moulé et l'autre non moulé, et un procédé de fabrication d'un tel coeur de croisement. Coeur de croisement caractérisé en ce que l'élément (3) est en acier moulé dont au moins les deux extrémités (3A et 3B) côté pointe et les deux extrémités (3C et 3D) côté talon sont conformées en profil de rail, mais seul le profil de rail des deux extrémités (3A et 3B) servant effectivement au roulement, l'élément non moulé (4) étant principalement constitué de pièces (5 et 5′) réalisées intégralement en rails et reliées aux deux extrémités (3C et 3D) côté talon de la pièce moulée (3), mais ni le profil de rail des deux extrémités (3C et 3D) ni le profil de rail des pièces (5 et 5′) ne servant effectivement de surface de roulement, la pointe mobile (1) étant, quant à elle, réalisée intégralement en rails dont toutes les faces supérieures servent effectivement de surface de roulement.
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).
摘要:
Die Erfindung betrifft eine Vorrichtung zum Verschieben einer zwischen zwei Flügelschienen (10a,10b) beweglichen Herzstückspitze (1) einer Gleisanlage, wobei die Flügelschienen (10a,10b) mit einem feststehenden Rahmen (2) und die Herzstückspitze (1) mit einem beweglichen Rahmen (3) verbunden sind und der bewegliche Rahmen (3) relativ zum feststehenden Rahmen (2) über eine außerhalb des von den Flügelschienen (10a,10b) aufgespannten Raums (B) angeordnete Rollenanordnung (4,5) verschiebbar gelagert ist.
