Overhead monorail train system

Abstract

The invention discloses an overhead single-track train system, which is a single-track train running between an upper and a lower auxiliary main single tracks and an overhead single-track system in which an upper and a lower rows of multiple tracks formed by two pairs of main auxiliary single tracks arranged on both sides of the same I-shaped beam. The single-track train is a light main auxiliarysingle-track train which consists of narrow train body with small cross section, a plate-shaped shock absorber, a main track wheel motor directly driving a main track wheel, an auxiliary wheel in parallel with the train and a small single main track wheel for bearing; the main structure of the overhead single track is a main bearing beam with I-shaped cross section, which consists of an I-shaped upper flange of girder, a horizontal lower flange and a middle vertical wall; both the upper and the lower flanges are structures with thick root and thin flange edge; the middle vertical wall is provided with a structure hole; the I-shaped beam of the upper flange is formed by an auxiliary track support arm, in which the main body is a reversed T-shaped main beam; the T-shaped beam structure is the same with a corresponding part of the entire I-shaped beam; the main single tracks are paved at the edge of the lower flange; the auxiliary single tracks are arranged on the edge of the upper flange or the top of the single-track support arm; both ends of the I-shaped beam are supported by a T-shaped pier; the invention is characterized by low cost, low energy consumption and low noise.

Description

technical field [0001] The invention relates to an elevated train and a track system belonging to a three-dimensional transportation system. In particular, it relates to an up and down double-track monorail system and an elevated monorail system for running trains that are co-located on an I-shaped main girder Background technique [0002] The elevated track in the modern transportation system is a three-dimensional transportation form with low cost and less land occupation, which is superior to subway and ground transportation. However, the traditional elevated track structure is huge and clumsy. For example, the track bridge of the double-track elevated urban rail is more than 7.5 meters wide. The wider track bridge not only increases the weight of the bridge body, but also requires the use of heavy double-column piers, which is expensive and takes a long time. The wide bridge itself blocks the surrounding environment, affects the vision and the growth of adjacent vegetat...

Problems solved by technology

This overly conservative design also affects its cost, operating cost and penetration rate, and also causes actual inefficiency and high energy consumption.

The characteristics of short-distance transportation on urban rail, frequent start and stop, and clumsy trains are difficult to meet the requirements of convenience and energy saving

Although there are a variety of ideas for new urban rail, such as jet propulsion suspension trains, etc., there are still technical, cost and safety issues that need to be resolved
