Travel structure of magnetic levitation type rail polling car

Abstract

The invention provides a travel structure of a magnetic levitation type rail polling car, wherein the travel structure is fixedly arranged at the lower part of the bottom board of carriage of the rail polling car and comprises a plurality of floating frames which are sequentially arranged as well as a long stator linear motor traction device and an outer rotor motor driven supporting wheel devicewhich are arranged on the floating frames; wherein the floating frames comprises a plurality of beam frames and corbel frames which are arranged at the two ends of the beam frame; the long stator linear motor traction device comprises a floating magnet module arranged on the corbel frame, a plurality of guiding magnet modules and a plurality of eddy braking magnet modules; the outer rotor motor driven supporting wheel device comprises a motor supporting wheel loading device which is arranged at the two ends of the beam frame and at the inner side of the corbel frame as well as an outer rotor motor supporting wheel arranged at the two ends of the bottom of the beam frame by the loading device. The invention can realize the compatible double traction pattern of long stator linear motor traction and outer rotor motor supporting wheel traction, so that the rail polling car can have the functions of high speed polling and low speed detection.

Description

technical field [0001] The invention relates to a special vehicle structure in the field of high-speed maglev transportation, in particular to a running structure of a maglev track inspection vehicle. Background technique [0002] The development of high-speed constant conduction electromagnetic levitation transportation technology has realized the wish of human beings to run at a high speed of 500km / h on the ground. Although this technology has not been widely used, the guarantee of operation safety is a matter of great concern. In view of the technical characteristics of the small suspension gap (about 10.0mm) between the high-speed maglev vehicle and the track, it is required that the track inspection must be carried out before the maglev train runs. Such as figure 1 As shown, it is a structural schematic diagram of the track 7 of the high-speed constant conduction electromagnetic suspension transportation system. The main structure part 7f of the track 7 is a concrete...

AI Technical Summary

Problems solved by technology

However, there is a key defect in these track inspection vehicles mentioned above, which cannot run at high speed, that is, they do not have the conditions for high-speed inspection operation

For the high-speed maglev transportation system with long routes, if a long outage "skylight" time is reserved for track inspection, it will greatly affect the transportation capacity of passenger lines
