Vehicle fault emergency disposal of the freight train vehicle thermal shaft emergency disposal

Vehicle fault emergency disposal of the freight train vehicle thermal shaft emergency disposal - 2019 11 - 15 ( Lanzhou west locomotives) Operating procedure key points: 1. The driver received a train dispatcher (in the train Station attendant) Vehicles bearing strong heat ( About 90 ℃ or more than 55 ℃ temperature) After the notice, should according to the requirements of the instructions of the speed limit, etc. , and stood in front of the using common parking brake. 2. The driver received a train dispatcher (in the train Station attendant) Vehicles bearing hot ( More than 120 ℃) After the notice, should be used according to the instructions immediately commonly used parking brake. 3. Stop stop disposal criterion between excitation hotspots: when the bearing outer ring is a new circular grinding crack, grinding out of scrap iron, outer ring damaged, deformation, discoloration, Blue or red) , smoke, oil seal cover of emergence, swing, through oil shock heat or burning, timely report the train operator to deal with. 4. When not the bearing fault, after the driver to correct temperature measuring in time report to train dispatcher, according to the scheduling command speed limit is 25 km/h runs to the front to the nearest station or by no more than 15 km/h back to this site. 5. Shaft temperature measurement methods: back in fault axis direction ( The lower part) Temperature measured by infrared thermometer, the port is apart from the outer surface of the rolling bearing ( Right) No greater than 100 mm; The outside temperature shall be measured bodywork chassis parts well in the shade. Risk prevention and control key points: 1. No blind operation. 2. Disable the method such as sand, water cooling. 3. Accurate temperature measurement, the correct report. 4. Standard hot box truck into micro heat, strong heat, heat shock level 3, micro heat tracing, strong heat stop ahead, heat shock stop immediately.
