Bow raising air source system of railway vehicle

Abstract

The invention relates to a bow raising air source system of a railway vehicle. The bow raising air source system of the railway vehicle comprises an installing frame which is provided with an air compressor. One end of the air compressor is connected with a socket through a cable, and the socket is connected with the compressor and supplies power to the air compressor through a plug. The other end of the air compressor is connected with a check electromagnetic valve through an air guiding pipe. The check electromagnetic valve is connected with the air inlet end of a drier and a safety valve through the air guiding pipe. A heater and a pressure switch are installed on the drier. A regenerative opening of the drier is connected with an air storage barrel through the air guiding pipe. The output end of the drier output supplied air through the air guiding pipe. A support is connected with the installing frame. The bow raising air source system of the railway vehicle is compact and reasonable in structure and firm in installation, an assembly is light, the motor burnout phenomenon cannot be caused easily, vibration is small, and the air leakage and electric leakage phenomena cannot be caused easily because vibration is small.

Description

technical field [0001] The invention belongs to the technical field of rail vehicle equipment, and in particular relates to a rail vehicle bow raising wind source system. Background technique [0002] The lifting wind source system of rail vehicles is a device used to raise the pantograph on the roof of the subway car. Its working principle is: after the driver gets on the car, he closes the key, then closes the corresponding switch, and uses the electric power of the battery under the car to drive the auxiliary air pump to work to generate compressed air with a certain pressure. When the air pressure reaches a certain value, it passes through the transmission cylinder to the air spring, and the air spring expands to push the wire rope to drive the lower arm of the pantograph to move. The lower arm supports the upper arm and the bow head with the assistance of the pull rod, and the bow head is in balance. Under the action of the rod, the horizontal state is guaranteed, and ...
