Passive trolley suitable for multiple vehicle types

The invention discloses a passive trolley suitable for multiple vehicle types. The passive trolley suitable for the multiple vehicle types comprises a passive trolley platform which walks along a track and has a lock function, the passive trolley platform is provided with a fixed primary standard structure, a three-way stepless standard support mechanism and/or a two-way stepless standard support mechanism and/or a support stepless standard mechanism. The passive trolley can be simultaneously suitable for the multiple vehicle types, and by means of multiple adjustable stepless standard support mechanisms, multiple vehicle type stepless switching of the passive trolley is achieved. A walking power source of the passive trolley and a power source of a switching mechanism are independently arranged on the exterior of the passive trolley, the weight of the trolley is reduced, and the trolley is portable and simpler. According to the passive trolley suitable for the multiple vehicle types, a support pressing mechanism and a support part which make contact with a trolley body are connected with the passive trolley through insulating parts, and welding electric leakage is avoided.
