Patent

CA 2312364

A rail restraining (1) and weld delivery device (100) uses a frame for supporting a welding head with a clamp (3) for restraining a first rail end and a second rail end and a base twist assembly (17) for aligning said first end and second end. An interconnected weld containment apparatus (290) pivotally connects to the clamp by use of a cam actuated linear pin (7). This arrangement is operable in an environment in which clearance between rails is about 7 to 11 inches and sufficiently compact that it may be operated from and carried in a truck based on a standard over the road truck.

L'invention concerne un dispositif d'immobilisation de rails (1) et de formation de soudures (100) utilisant un châssis, qui soutient une tête de soudage au moyen d'une pince (3) afin de retenir une première extrémité de rail et une deuxième extrémité de rail, ainsi qu'un ensemble de base de torsion (17) destiné à aligner lesdites première et deuxième extrémités des rails. Un appareil de retenue de soudures interconnectées (290) est relié pivotant à la pince au moyen d'un ergot linéaire (7) actionné par came. Ce dispositif s'utilise lorsque le gabarit des rails est de 7 à 11 pouces. Il a une taille suffisamment compacte pour pouvoir être transporté dans un camion conventionnel et utilisé depuis ce camion.
