The invention relates to a high-speed rail vehicle rescue device, in particular to a vehicle bogie fault rescue bearing trolley. The problem that rescue is difficult when an existing bogie breaks downis solved. The bearing trolley is formed by assembling a plurality of sets of monorail trolleys, each monorail trolley comprises an inner side frame, an outer side frame, a wheel set and a supportingshaft, the wheel sets and the supporting shafts are arranged in journal grooves, and the supporting shafts are connected with the inner side frames and the outer side frames into a whole; vehicle bogie wheels are fixedly connected into the journal grooves through fasteners, and each supporting shaft is supported at one side of the corresponding vehicle bogie wheel; and the supporting shafts are each of a variable cross-section special-shaped structure, and the supporting faces of the supporting shafts are tread contours. According to the vehicle bogie fault rescue bearing trolley, the runningcapacity of an accident vehicle is restored, a train does not need to be decompiled or a fault bogie does not need to be replaced, and effective means and equipment guarantee are provided for vehiclebogie and wheel set fault rescue.
