The invention discloses a rail vehicle brake airtight test dolly, and relates to the technical field of the airtight test apparatus. The dolly comprises a dolly and an airtight pipe system arranged onthe dolly. The airtight pipe system comprises a transverse pipe, and a pressure gauge, a cutout cock with a side discharge and an air inlet hose quick connector are arranged at one end of the transverse pipe. Longitudinal pipes are arranged on the transverse pipes, longitudinal cut-off cock doors are arranged on the longitudinal pipes, and exhaust port hose quick connectors are arranged at the bottoms of the longitudinal pipes. After the pipe row is assembled, the end of the air outlet side pipeline is blocked through a pipe plug, the pipe row is connected with the air outlet end through a quick insertion hose and an adapter substitute, the air inlet end is connected with an air source, the pipe row pipeline is filled with compressed air, and the pipe row airtight pressure test is achieved. After the whole vehicle brake pipeline and the BCU control module are assembled, hoses and steel pipes which are not connected with equipment are blocked, the air outlet end of the airtight trolleyis connected with a vehicle end main air hose through a quick insertion hose and an adapter substitute, the air inlet end of the airtight trolley is connected with an air source, and a whole vehiclebrake pipeline pressure test is achieved.

    本发明公开一种轨道车辆制动气密试验小车,涉及气密试验装置技术领域,包括小车和气密管系,气密管系设于小车上;气密管系包括横向管,横向管一端设有压力表、带侧排截断塞门和进气口软管快插接头;横向管上设有纵向管,纵向管上设有纵向截断塞门,纵向管底部均设有排气口软管快插接头。管排组装完成后用管堵对出风侧管路端部进行封堵,用快插软管和转换接头将管排与出气端进行连接,进气端连接气源,管排管路中充入压缩空气,实现管排气密压力试验。整车制动管路及BCU控制模块组装完成后对未连接设备的软管及钢管进行封堵,用快插软管、转换接头将气密小车出气端与车端总风软管进行连接,气密小车进气端连接风源,实现整车制动管路压力试验。
