Example Embodiment

[0028] The following structural drawings and specific implementations further describe the present invention in detail:

[0029] Such as figure 1 As shown, a plurality of brake pipelines 1 for vehicle braking run through the bottom of the rail vehicle, and this embodiment uses four brake pipelines 1 as an example for detailed description.

[0030] The rail vehicle brake pipeline cleaning and sealing detection device includes an air compressor 9 for supplying high-pressure air to the intake pipe 2, and an air filter is connected between the air compressor 9 and the intake pipe 2 10. It is used to filter the impurities blown into the intake pipeline 2 to ensure that the pipeline is not recontaminated by external air during the cleaning and sealing test process, so as to ensure that the cleanliness of the brake pipeline 1 meets the design requirements of rail vehicles .

[0031] Matching with the brake pipe 1, four air intake pipes 2 and four air outlet pipes 3 are provided in this em...

Abstract

The invention relates to a method and a device for washing and seal detecting of railway vehicle braking lines. Air inlet lines and air outlet lines are communicated with each other at the inlet end and the outlet end of each braking line, an air inlet solenoid valve is arranged on each air inlet line, a plugging solenoid valve is connected with each air outlet line correspondingly, a pressure sensor used for detecting the air pressure in the line is arranged on each of the air outlet lines, and the air inlet solenoid valves, the plugging solenoid valves and the pressure sensors are respectively connected with a microcomputer. The microcomputer controls the opening and closing of the air inlet solenoid valves and air outlet solenoid valves according to the detected air pressure in the lines so as to complete the air inflation, exhausting and pressure maintaining process of the braking lines and merge line washing equipment and seal detecting equipment into a whole to complete the line washing and the seal detecting at one time; and the operation is simple, few equipment is required, and the cost is low; and the equipment operation is controlled by the microcomputer automatically, so that the labor intensity of workers is lowered, and the line washing and the quality as well as the precision of the sealing property detection can be ensured.

Description

technical field [0001] The invention relates to a pipeline cleaning method and device, and a pipeline sealing detection method and device, in particular to a method and a pipeline cleaning and pipeline sealing detection method for rail vehicle brake pipelines that can be completed at one time. The device belongs to the technical field of rail vehicle manufacturing. Background technique [0002] The current rail vehicles are all braked by air. The bottom of the vehicle runs through the air pipelines used for vehicle braking. During the pre-treatment of these air pipelines, the large impurities and dirt in the pipelines have been removed. However, during the process of assembling these pipelines to the vehicle, some impurities such as debris will accumulate in the pipeline. In order to ensure the braking performance of the vehicle, the air pipeline of the vehicle must be sealed and clean, which is to ensure the safety of the braking equipment. The key to running and ensuring ...
