Abstract

The invention discloses a cleaning device and a cleaning system suitable for a whole railway vehicle braking system. The cleaning system comprises a braking pipeline, a high-pressure air source and a cleaning device body, wherein the high-pressure air source and the cleaning device body are connected to the two ends of the braking pipeline respectively; the cleaning device comprises a cleaning gas circuit, a power supply unit, a control unit and a man-machine interface unit; a filtering pressure regulating valve, a pressure detection device and an electromagnetic valve are sequentially arranged between an air inlet and an air outlet of the cleaning gas circuit; a signal output end of the pressure detection device and control ends of the filtering pressure regulating valve and the electromagnetic valve are respectively connected with the control unit; the man-machine interface unit receives an external control instruction and transmits the external control instruction to the control unit, and the control unit controls the on-off state of the electromagnetic valve according to the received external control instruction so as to perform on-off control on the clean gas path; and the control unit controls the filtering pressure regulating valve to regulate the pressure according to the gas path pressure signal and a preset pressure reference value. The device is easy, convenient and accurate to operate, and can provide effective guarantee for cleaning of a braking system and reliability of braking performance.

Description

technical field [0001] The invention relates to a cleaning device and a cleaning system suitable for a whole vehicle braking system of a rail vehicle, belonging to the technical field of rail transportation. Background technique [0002] As one of the important systems of rail vehicles, the braking system has a direct impact on the operating status of the vehicle, and the blockage of the braking system will cause the braking command on the vehicle to fail to reach the terminal braking device, resulting in braking failure and accidents. . Therefore, the cleanliness of the brake system has a direct impact on the braking performance, and the cleanliness of the brake pipeline is particularly important as a component connecting various equipment. Since the air inlets of the main brake-related equipment are equipped with filters, and the inside has been cleaned, the cleaning of the brake system is mainly the cleaning of the inside of the brake pipeline. There are three main ways ...
