Abstract

The invention discloses a depressed center flat car for urban rail vehicle maintenance, and relates to the technical field of rail vehicles. The depressed center flat car comprises a chassis, a wind braking device, a manual braking device, an electrical device, a vehicle coupler buffering device and a bogie, wherein the electrical device arranged on the end part of the chassis comprises an illuminating element and a power source of the illuminating element; the chassis comprises an end beam, a sleeper beam, a drawing beam, grids, a floor, a lower cover plate and two opening covers or more; the drawing beam of a knife-holder-type hollow frame structure comprises a dovetailed external end part, a middle part and a bending part; the dovetailed external end part is connected with the vehicle coupler buffering device; the middle part is connected with the sleeper beam; the bending part is connected with the grids; the lower end surface of the middle part is higher than lower end surfaces of the external end part and the bending part; each of the sleeper beam, the drawing beam and the grids is internally and vertically provided with web plates at intervals. The depressed center flat car disclosed by the invention has the advantages that the features of simple structure, convenience in use, large loading capacity, high overall strength, high applicability and the like are obtained; the flat car is suitably applied to the operation on standard gauge lines, and is mainly used for the maintenance of subway rail lines; cargoes loaded by the flat car are equipment mainly used for maintaining the subway rail lines.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a concave-bottom flat car used for maintenance of urban rail vehicles. Background technique [0002] With the acceleration of the urbanization process in all countries in the world, the pressure brought by the increase of urban population to urban traffic is becoming more and more obvious. Therefore, the subway has become a new channel to relieve the pressure of urban traffic. At present, major and medium cities in the world are doing their best to develop subway traffic. With the extensive use of subways, the maintenance and repair vehicles of daily lines also increase. [0003] At present, the application of concave-bottomed flat cars has become more and more extensive. Since the concave-bottomed flat cars are carried by the floor surface of the concave bottom part, the height of the cargo will not exceed the limit after loading by reducing the height of the floor surfac...
