Abstract

L'invention concerne un dispositif de démontage et d'assemblage de cadre de suspension amortissant les vibrations pour un train à sustentation magnétique. Le dispositif comprend des colonnes support (11), des ensembles de roues porteuses (34), une base (31), des mécanismes de levage (33), une table support (32), un rail de levage (321), un ensemble de verrouillage gauche (351) et un ensemble de verrouillage droit (352). Un ensemble d'amortissement de vibrations (4) comprend un premier cylindre à filet (41), une tige filetée (42), une poignée (43), un cylindre de transmission de force (44), un deuxième cylindre fileté (45), un vérin de levage (46), une tige de transmission (47), un cylindre de liaison (48), un bloc de contrepoids (49) et un couvercle d'étanchéité (410). La présente invention permet de réaliser le démontage et l'assemblage d'un cadre de suspension de train à sustentation magnétique, et le démontage et l'assemblage sont très commodes. De plus, dans des circonstances normales, la présente invention peut également servir de partie du rail dans un hangar à sustentation magnétique, garantissant ainsi le fonctionnement normal d'un train à sustentation magnétique dans un hangar d'inspection et de maintenance. L'objet de l'invention comporte un mécanisme de support central qui permet d'obtenir un bon effet d'amortissement des vibrations afin de résoudre le problème de l'état de la technique selon lequel, pendant le processus de sustentation magnétique du train à sustentation magnétique, un réglage à haute fréquence de l'espace libre de sustentation magnétique est susceptible de générer une résonance avec une structure se trouvant au-dessous. En même temps, lorsque le cadre de suspension de train à sustentation magnétique doit être démonté et assemblé, le rail de levage peut entraîner le cadre de suspension de train à sustentation magnétique pour l'abaisser, ce qui facilite le démontage et l'assemblage du cadre de suspension de train.
