Technical Field
[0001] This utility model relates to the field of magnetic levitation train track inspection and cleaning technology, and in particular to an electric tire-type traction inspection service vehicle. Background Technology
[0002] High-speed maglev trains, as a key scientific research project, represent an important development direction in the rail transit field. While commercial operation of high-speed maglev trains has been achieved abroad, technological blockades are imposed on their supporting traction service equipment. Domestically, related fields are still in the exploratory stage, lacking targeted comprehensive service solutions. Existing equipment is mostly designed for single functions, such as independent track inspection vehicles, traction vehicles, or snow removal equipment, which cannot meet the comprehensive operational needs of maglev train lines. When multiple devices work together, scheduling becomes complex and inefficient. Ordinary rail transit equipment is not compatible with the U-shaped track structure of superconducting maglev trains, and lateral deviation is prone to occur when running on curves. Balancing power output and wheel-rail adhesion under heavy traction conditions is also difficult.
[0003] Therefore, there is an urgent need to develop an integrated and highly adaptable electric tire-type traction and inspection service vehicle to fill the domestic technological gap and break through foreign technological blockades. Utility Model Content
