Abstract

L'invention concerne un chariot de déplacement (A) qui comporte une pluralité de galets de guidage soudés par pression à une plaque debout (2) et qui circule sur une plaque transversale (1), fait se déplacer un chalumeau de traitement (18) le long d'une ligne cible de traitement après avoir atteint une limite de déplacement et rend facile à exécuter une opération de réglage qui est nécessaire quand on change de direction de déplacement. Le chariot est constitué des éléments suivants : une pluralité de bras de support (10b, 11b) qui comportent des galets de guidage (10a, 11a) sur leur bout et sont disposés de telle sorte qu'on peut régler leur position de fixation pour obtenir une position prescrite pour un corps principal (12) de chariot ; un porte-chalumeau (15) qui tient le chalumeau de traitement ; un élément de guidage (16) du porte-chalumeau, dont les côtés terminaux dans le sens de longueur sont fixés à un endroit prescrit sur un bras de la pluralité de bras de support de telle sorte qu'on puisse régler leur angle et qui guident le mouvement du porte-chalumeau ; et un dispositif d'entraînement (17) du porte-chalumeau qui déplace le porte-chalumeau le long de l'élément de guidage du porte-chalumeau. Cette structure est telle qu'on peut régler l'angle de l'élément de guidage du porte-chalumeau avec le corps principal de chariot en même temps que l'on règle la position de fixation du bras de support sur le corps principal de chariot.
