Abstract

The invention relates to the technical field of electric locomotives, in particular to a rail flaw detection vehicle for a subway. The rail flaw detection vehicle comprises a cab, a frame, a bogie, a diesel engine unit, a carriage, an air source system, a detection room, a flaw detection unit and an electrical cabinet. The cab, the diesel engine unit, the detection room and the electrical cabinet are mounted inside the carriage; the carriage is connected to the top of the frame; the bogie, the air source system and the flaw detector are connected to the bottom of the frame; an alternating current and direct current electric transmission device is disposed inside the carriage; the flaw detection unit comprises a lifting bar, a stabilizer bar, a detection wheel, a detection bar and a flaw detector. The alternating current and direct current electric transmission device is disposed in the carriage to serve as a built-in drive power of the vehicle, standalone travelling is available, the flaw detector is in a slipping boot structure, the speed can be greatly increased at the premise of detection quality guaranteed, maintenance of parts is low, application and maintenance costs are low, and the vehicle has important significance to lowering domestic user cost and improving operating efficiency.

Description

technical field [0001] The invention relates to the technical field of electric locomotives, in particular to a rail flaw detection car for subways. Background technique [0002] The rail is the main component of the railway track. Its function is to guide the wheels of the rolling stock, bear the huge pressure of the wheels, and transmit it to the sleeper. The rails must provide the wheels with a continuous, smooth and least drag rolling surface. Therefore, in order to ensure the safe operation of the locomotive, the railway system needs to conduct flaw detection on the rails frequently to detect fatigue defects and welding defects in the rail head and rail waist range (including near the joint), as well as rail bottom corrosion and crescent blocks , rail head crushing and other damages, so that remedial measures can be taken in time to prevent problems before they happen. At present, domestic flaw detection vehicles are basically unpowered, unable to walk alone, and have...
