Abstract
With the development of urban rail transit in China, railway and urban rail transit have developed rapidly. More than 30 cities have opened urban rail transit. An increase in the number of infrastructures also means an increase in the frequency of equipment failures, which requires efficient maintenance of equipment. Equipment to ensure that the failure of equipment can be timely maintenance or replacement. The dual-use high-altitude work vehicle has the advantages of flexibility and adaptability, and can transfer personnel and equipment to specific locations for air operations by using rail transit and highway traffic, which is more advantageous than the traditional high-altitude work vehicle and high-altitude work vehicle. However, the domestic research on road-to-rail dual-use aerial work vehicle is not very mature, so we need to increase the research investment in this aspect. This design mainly provides an overall layout plan of a road-and-rail dual-purpose high-altitude work vehicle. The special work vehicle of this plan can not only complete the basic functions of ordinary cars, but also realize the functions of upper rail, lower rail, rail running and high-altitude work. This paper describes the selection and change of the chassis of this kind of vehicle, the layout of the force extractor, the overall structure design and hydraulic circuit design of the aerial work device, the overall structure design and hydraulic circuit design of the rail driving system (mainly bogie), and so on.

Keywords:roadway/rail dual-purpose aerial work vehicle; General layout; Articular-arm high-altitude working platform;Single-shaft power bogie.
