High-speed maglev track and bridge beam part structure containing longitudinal-cross beam type track section

Abstract

The invention discloses a high-speed maglev track and bridge beam part structure containing a longitudinal-cross beam type track section. The high-speed maglev track and bridge beam part structure includes a concrete beam (1) and a rail supporting table (2) arranged at the top of the concrete beam (1), and further includes the longitudinal-cross beam type track section which is installed on the rail supporting table (2) through a fastener system (3), and includes two longitudinal beams arranged in the circuit direction and a plurality of cross beams arranged in the direction perpendicular to acircuit; and the cross beams include track section cross beam top plates (4), track section cross beam bottom plates (5) and track section cross beam web plates (6), and the longitudinal beam includes sliding top plates (7) of track functional parts, magnetic guiding plates (8) of track functional parts, track section longitudinal beam web plates (9) and pi-shaped steel (10). According to the structure, the track structure is completely separated from the bridge structure, a longitudinal-cross beam type track section rail is used, the precision in all directions can be precisely positioned bythe post-cast rail supporting table during construction, and during operation and maintenance, the rail elevation can be adjusted through the fastener system.

Description

technical field [0001] The invention belongs to the technical field of maglev rail transit, and more specifically relates to a high-speed maglev rail and bridge beam structure including longitudinal and cross beam rail rows. Background technique [0002] The maglev transportation system is a new type of ground passenger transportation system. The significant difference from the traditional wheel-rail transportation system is that the car body is suspended above the track by means of the suspension force, and its walking part does not contact the track. The propulsion generated by the linear induction motor moves forward on the track. The charged levitation electromagnet on the levitation frame of the high-speed maglev train and the long stator coil on the track attract each other to provide the levitation force for the train to lift the train upward, and ensure a stable levitation gap by controlling the levitation excitation current. The suspension gap between the electroma...
