摘要:
A swing nose crossing has the swing nose (18) housed in an insert component (24) which itself is mounted within the wing rails (20, 22) of the swing nose crossing. The cradle (24) provides the lateral faces against which the swing nose abuts.
摘要:
A railway crossing comprises a base (9), four rail support arms (12, 13, 16, 17), a rail crossing bar (29), and a displacement means (30) for displacing the rail crossing bar (29) between the first and second positions. The first and second rail support arms (12, 13) converge from an entrance aperture (14) for receiving first and second inbound rails (22, 23) to a waist (15). The third and fourth rail support arms (16, 17) diverge from the waist (15) away from the entrance aperture (14) to an exit aperture (18) for receiving first and second outbound rails (31, 32). The arms (12, 13, 16, 17) define a long axis extending from the entrance aperture (14) to the exit aperture (18) through the waist (15). Each arm (12, 13) is parallel to the arm (16, 17) on the opposite side of the waist (15) and long axis. The rail crossing bar (29) is received at one end in the waist (15) and is free to be pivoted about the waist (15) between the first and second positions where it abuts the first and second arms (12, 13) respectively.
摘要:
Ce coeur de croisement comprend : - un ensemble de berceau comportant une partie d'encastrement (12) pour pointe mobile, qui possède deux éléments de talon (35, 36) espacés l'un de l'autre, - une pointe mobile montée dans l'ensemble de berceau en étant encastrée dans la partie d'encastrement (12), - des pièces d'entretoise (63) interposées entre les éléments de talon (35, 36) et la pointe mobile, et - des moyens (70, 81, 83) de fixation démontable de la pointe mobile dans la partie d'encastrement (12). Les pièces d'entretoise (63) sont fixées de façon démontable sur les éléments de talon (35, 36) par lesdits moyens de fixation démontable (70, 81, 83), de telle sorte que le démontage vertical (Z) de la pointe par rapport à l'ensemble de berceau est possible.
摘要:
Die Erfindung bezieht sich auf ein Herzstück einer Rillenschienenweiche mit einer auf einer Gleitplatte (34) beweglich angeordneten Herzstückspitze (12), entlang dieser verlaufenden Flügelschienen (16, 18) sowie in Anschlussschienen (20, 22) übergehenden Hilfsschienen (24, 26), die jeweils mit einem Abschnitt einer der zugeordneten Flügelschienen eine Rille (40, 42) begrenzen. Um bei einfacher Konstruktion im gewünschten Umfang die Herzstückspitze verstellen zu können und im Falle von Wartung bzw. einer Erneuerung einen problemlosen Austausch zu ermöglichen, wird vorgeschlagen, dass die Herzstückspitze (12) verbindungslos in die Hilfsschienen (24, 26) übergeht.
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:
An improved railroad trackwork spring wing frog (10) is provided with a rail-closer (70) having a single compression spring (72) whose reaction forces are applied to the frog spring wing rail (50) through movable linkages (78, 80) that are each connected to the spring wing rail (50) at different spaced-apart position and that each abut the single compression spring (72).
摘要:
The railroad trackwork spring wing frog assembly is provided with multiple rail-closer subassemblies (70), preferably of the nested and counter-wound compression spring-type, that co-operate with the assembly spring wing rail (50), and that are laterally spaced-apart with respect to each other along the angled rail portion (58) of the frog assembly spring wing rail (50).
摘要:
Die Erfindung bezieht sich auf eine Anordnung zum Niederhalten einer zwischen Flügelschienen (14, 16) angeordneten und auf einer Unterlage wie Gleitstuhl (18) abstützbaren Herzstückspitze (12). Um einerseits ein sicheres Niederhalten und andererseits eine leichtgängige Verstellung zu ermöglichen, wird vorgeschlagen, daß ein Element (20) die Herzstückspitze (12) durchsetzt, das wahlweise die Herzstückspitze in Richtung der Unterlage drückt oder diese freigibt.
