Description

Technical Field

[0001] The present invention relates to the technical field of rail transportation, and in particular to a suspended monorail transportation system. Background Art

[0002] In a suspended monorail system, the track beam adopts a steel box structure with an opening at the bottom, and the span is generally 25m to 30m. The running part of the vehicle is located in the track beam, and the vehicle running part is provided with running wheels and guide wheels. The running wheels act on the top surface of the bottom plate of the track beam to transfer the vehicle load to the track beam system; the guide wheels act on the inner side of the track beam to guide the vehicle. Due to the use of a steel box structure with an opening at the bottom, the bottom plate of the track beam will be compressed and deformed under the action of the vehicle's gravity, which will lead to uneven contact between the guide wheels and the beam body, which will eventually manifest as a large swaying of the vehicle and low comfort. In order to ensure that the track beam has sufficient vertical, lateral and torsional stiffness and stability, the track beam is provided with circumferential and longitudinal stiffening ribs. The engineering volume is large but the spanning capacity is limited. Therefore, the present invention provides a suspended monorail transportation system. Summary of the Invention
