A three-degree-of-freedom series-parallel vibration damping pantograph, comprising an armature drive system fixed to a base, and a pantograph bow, and further comprises transverse dampers, a parallel supporting frame and longitudinal dampers. Square auxiliary holes are formed in the base, and supporting insulators are arranged on the four corners below the base. The four transverse dampers are symmetrically fixed to the base, and the transverse dampers are arranged on the outer side of the parallel supporting frame and connected to the parallel supporting frame through hinges. The four longitudinal dampers are symmetrically fixed to the top of the parallel supporting frame. The pantograph bow is connected to the parallel supporting frame through the longitudinal dampers, and a separator is arranged on the pantograph bow. The pantograph can overcome the technical defects of an existing pantograph, bearing and vibration damping in the directions of three degrees of freedom in space can be achieved, accidents such as pantograph disengagement and net scratches can be avoided, structural stability of the pantograph and adaptability to a touch net are improved, and the pantograph further has the advantages of being stable and reliable in work, convenient and fast to operate and maintain and the like.
