Problems solved by technology

[0005] It is a very complicated problem to further optimize the track girder of rail transportation on the basis of the existing design, and the optimization of one aspect of performance index will often bring complex effects on other aspects of performance index
Under such a connection setting method, the manufacturing precision of the track beam is not high, and at the same time, its fatigue resistance is reduced, and the lateral stiffness and longitudinal stiffness are not ideal, especially when carrying a load of more than 60 tons and a vehicle speed of more than 30km / h. The deformation of the transverse opening of the track beam is usually greater than 20mm, which may easily lead to problems such as unstable driving of the power bogie

Abstract

The invention relates to the field of rail transit transportation, in particular to a monorail girder and a monorail transportation system. The monorail girder forms a walking space by using the space between three independent bodies. According to the monorail girder and monorail transportation system, the gravity center of a carrying unit can be effectively reduced; meanwhile, the manufacturing process of the rail girder is simplified, the precision is improved, and the anti-fatigue capability is improved; under the situation of the same material weight and load, the longitudinal rigidity performance and the transverse rigidity performance of the track girder can be better.

Description

technical field [0001] The application relates to the field of rail transportation, in particular to a monorail beam and a monorail transportation system. Background technique [0002] In the existing field of rail transportation, it usually involves suspension transportation, straddle transportation, etc. No matter what kind of transportation mode, it will involve the structural design of track beams; Structural beams, H-beams in straddle transportation, T-beams, etc. [0003] A box-type structural beam is usually assembled from several structural parts, and the assembly methods include welding, bolting, etc. For details, please refer to the patent application CN201610944898.7. [0004] H-shaped beams or T-shaped beams can usually be made by pouring concrete and assembling steel materials, such as patent applications CN201811023548.2 and CN201120054185.6. Contents of the invention [0005] It is a very complicated problem to further optimize the track girder of rail tra...
