Abstract

L'invention concerne des moyens de contrôle de l'état de la voie ferrée. Grâce à cette invention, la cinématique du dispositif de l'invention permet d'assurer un guidage continu et sans heurts ni chocs des convertisseurs d'un défectoscope mobile ou d'un autre dispositif diagnostique le long du centre des champignons de rails, qui tient compte de l'écartement, des inclinaisons, des arrondis et des inégalités de la voie, et qui évite toute projection dans la zone de travail, à la surface de roulement, de boue, de copeaux de métal et, en période hivernale, de neige ou de grains de glace. Dans cette invention, le chariot de support est constitué de deux chariots indépendants à axe unique, munis de ressorts à amortisseurs pneumatiques (vérins pneumatiques); le cadre de chaque chariot à axe unique est relié par un mécanisme en parallélogramme au cadre commun, et des poutres longitudinales sont montées sur les boîtes d'essieu des roues de poursuite des chariots à axe unique opposés; ces poutres permettent un déplacement longitudinal, avec possibilité de déplacement angulaire et axial des chariots à axe unique. Un système de recherche du défectoscope mobile est monté sur les poutres longitudinales.
