[0002] Acceleration of urbanization With the continuous acceleration of my country's urbanization process, the number of urban population has grown rapidly, and the travel needs of residents have gradually increased. Traditional modes of transportation can no longer meet people's needs. Therefore, it is necessary to use modern scientific and technological means to improve traffic conditions. Rail transit, as an important part of urban transportation, has the advantages of large carrying capacity, environmental protection, energy saving, and high efficiency. When a wheel set on the bogie of a train fails and cannot rotate, a wheel set rescue trolley is needed. The wheel set rescue trolley is a specially designed small, lightweight, and flexible temporary replacement device for bogie wheelsets. When the existing wheel set rescue trolley is working, when a wheel set on the bogie cannot rotate, the rescue personnel immediately use the wheel set rescue trolley to lift the faulty wheelset, and the rescue trolley replaces the wheel rotation, so that the faulty train can evacuate the scene as soon as possible, and the faulty vehicle can be quickly transferred to clear the line quickly. The traditional wheel set rescue trolley is fixed in size and cannot be adjusted according to the actual situation. When rescuing wheelsets of different sizes, it is necessary to replace wheelset rescue trolleys of different sizes, which is quite troublesome. For this reason, we propose a wheel set rescue trolley.
