Normally conductive electromagnetic levitation track inspection vehicle

Abstract

The invention provides a normal conducting electromagnetic levitation type rail polling car, wherein the polling car is in double traction pattern of long stator linear motor traction and outer rotor motor supporting wheel traction and can realize high speed polling at 200km / h and low speed rail detection at 60km / h. The polling car is provided with a plurality of floating frames, the formed travel mechanism is also provided with a plurality of outer rotor motor supporting wheels, an operating platform is arranged at the two ends of the shortened carriage structure by a lengthened carriage bottom board, and a lift maintenance platform and a car-ground communication device are arranged on the operating platform. A high speed video monitoring system and a high speed non contact rail detection device arranged in the head skit board which is specially designed, high speed and real time processing on detection data can be realized, and any fault of the rail can be reported in time and can be processed in time.

Description

technical field [0001] The invention belongs to special vehicles in the field of high-speed maglev transportation, and relates to a track inspection vehicle, in particular to a constant conduction electromagnetic levitation track inspection vehicle. Background technique [0002] The invention of high-speed maglev transportation technology in the last century has attracted worldwide attention. After the completion and operation of the Shanghai Maglev Demonstration Line, it has achieved the effect of fast, safe and environmentally friendly passenger transportation. [0003] Since the conventional maglev train is used for passenger traffic at a speed of 500km / h with a suspension gap of 10.0mm, there must be no negligence in the safety guarantee of the train operation. Therefore, the high-speed maglev transportation system as a passenger line must carry out track inspection work before the passenger train runs to ensure that there are no foreign objects on the line track, as we...

AI Technical Summary

Problems solved by technology

[0012] However, the above-mentioned requirements cannot be integrated on a patrol vehicle. The body structure of the original high-speed maglev passenger vehicle has chosen the structure of aluminum alloy extruded profiles and sandwich aluminum alloy composite panels, including the equipment interlayer as the load-bearing structure.

However, such a car body structure does not meet the structural requirements of rail inspection vehicles.

First of all, the equipment interlayer cannot be realized, and the entire load of the vehicle must be borne by the compartment floor

The second is that the space occupied by the motor support wheels on the running mechanism must be considered, which requires that some on-board electrical equipment must be installed in the compartment
