Abstract

The invention discloses a pantograph for rail transit, and relates to the technical field of pantographs of electric vehicles. The pantograph comprises a base, a lifting arm and a pantograph head. Anupper end of the lifting arm is connected with a micro-motion pantograph head, a central rotating shaft at a lower end of the lifting arm is rotatably mounted on the base, and a spring pantograph lifting device and a spring pantograph lowering device for driving the central rotating shaft to rotate are arranged between the central rotating shaft and the base; and the micro-motion pantograph head comprises a pantograph head support, an air bag spring and a carbon sliding plate assembly, the carbon sliding plate assembly is installed on the pantograph head support through the air bag spring, anda guide device for guiding a lifting direction of the carbon sliding plate assembly is arranged between the pantograph head support and the carbon sliding plate assembly. The air bag spring and the guide device are used in the pantograph head structure for cooperation, the spring pantograph lifting device is used for providing a pantograph lifting force, an air source is not needed in an operation process, and buffering performance, current collection stability and following performance of the pantograph head and the lifting arm are improved.

Description

technical field [0001] The invention relates to the technical field of pantographs for electric vehicles, in particular to pantographs for rail transit. Background technique [0002] Urban rail vehicles for urban use mainly include subways, light rails or trams. When the vehicles are running, they rely on the pantograph with the raised roof to contact the catenary to supply power to the vehicles. The pantograph head is an important part of the pantograph. The bow head is the part on the pantograph that is in contact with the catenary. Its working conditions are harsh, and its performance directly determines the current quality and reliability of the pantograph. . [0003] The Chinese invention patent with the application number 201120097224.0 discloses a pantograph for trunk line locomotives, which controls the raising and lowering of the pantograph through a double-airbag raising device. Its double-airbag bow-raising device includes connecting plate, steel wire rope assem...
