The invention discloses a trolley rail base. The trolley rail base comprises a base plate and a padding plate, wherein the padding plate comprises an elastic plate and a rigid plate which are mutuallyattached, and the elastic plate is used for directly pressing and attaching the bottom of a rail; a transverse fixing base is fixed on the padding plate and used for being fixedly connected with thebasic part of the rail; the padding plate is pressed and fixed on the base plate through a thread installing piece. The padding plate is provided with the elastic plate and the rigid plate in a multi-layer mode, the elastic plate can be a rubber material plate and the like and is directly attached to the bottom face of the rail, and the padding plate is pressed and fixed on the base plate in an installing mode of the thread installing piece; as the elastic piece is contained inside a base plate body in general, the elasticity of the padding plate and the elasticity of the base plate can be fully used in the thread-pressing-fixing mode, the rigid plate is pressed between two elastic plate pieces, the rail borne by a top layer can have the enough elastic limit in the water level and in the vertical direction, and the reduction performance of the rail base is effectively improved. The invention discloses a trolley rail.
Description
technical field [0001] The invention relates to the technical field of rail transportation, more specifically, to a trolley rail seat, and also to a trolley track. Background technique [0002] The track of medium and low speed maglev turnout trolley is the support device for the walking of medium and low speed maglev turnout trolley. When the maglev vehicle crosses the fork, the mid-span position of the active beam deforms vertically, and the vibration amplitude is the largest when vibration occurs. Therefore, the mid-span trolley track is effectively Vibration reduction is particularly important. [0003] At present, the vibration reduction measures for the trolley track are to arrange thinner rubber backing plates in sections under the track, and use pressure plates, special-shaped backing plates, studs, washers and nuts to compress and fix the tracks. In the actual operation of this scheme, the rubber backing plate is relatively hard, the contact area with the track is ...
