Abstract

The invention relates to an automatic testing device for the air tightness of a bogie brake pipeline. The automatic testing device comprises a quick plug, a pneumatic triple piece, a second electromagnetic switch control valve, an electromagnetic proportional control valve, a first ball valve controller, a first pressure sensor, a first pressure gauge and a first transition joint which are connected in sequence, wherein the electromagnetic proportional control valve is further sequentially connected with a second ball valve controller, a second pressure sensor, a second pressure gauge and a second transition connector; the quick plug is connected with a wind source; and the first transition joint and / or the second transition joint can be respectively connected with the brake pipeline. Theautomatic testing device for the air tightness of the bogie brake pipeline can compile an air tightness test program according to different brake pipeline air tightness test technical conditions, complete an air tightness test according to a set test program, and automatically print a test record after the test is finished.

Description

technical field [0001] The invention relates to the technical field of rail vehicle safety detection, in particular to an automatic airtightness test device for a bogie brake pipeline. Background technique [0002] The bogie is the running mechanism of the rail vehicle, and its structure includes the main components such as the driving device and the braking device. The braking device is an important guarantee for driving safety. Such as figure 1 As shown, the braking device includes a braking unit machine 100 and a braking unit machine 200 with a parking function, and the braking unit machine 100 and the braking unit machine 200 with a parking function are connected with a brake pipeline; The pipelines include a service brake pipeline 300 and a parking brake pipeline 400 . The brake device is the guarantee of driving safety. In order to ensure the safety of the brake pipeline during the use of the vehicle, it is necessary to conduct an air tightness test on the common bra...
