Embodiment 1

[0031] Embodiment one, such as Figure 1-2 Shown:

[0032] The present invention will be described in detail below in conjunction with the accompanying drawings. The internal structure of the maglev vacuum pipeline includes a main pipeline structure 1. The main structure 1 of the maglev vacuum pipeline bears the external load, and the inner bottom of the main pipeline structure 1 is set through along its length direction. The under-rail structure 9, the top of the under-rail structure 9 is provided with an inter-rail channel 5, and maglev tracks 4 located on both sides of the inter-rail channel 5, the ultra-high-speed maglev train 2 can run bidirectionally on the maglev track 4, and the two columns of maglev tracks 4 are respectively Located on both sides of the inter-rail channel 5, the setting of the inter-rail channel 5 can not only reduce the lateral force effect when the two vehicles meet, ensure the safety of vehicle operation, but also facilitate the evacuation of perso...

Embodiment 2

[0036] The inter-rail channel 5 is a closed structure connected with the under-rail structure 9, which is convenient for staff to overhaul the operating equipment in the under-rail structure 9.

Embodiment 3

[0038] The inter-rail passage 5 is an evacuation structure with a partially open roof. The top plate of the inter-rail passage 5 is provided with openings every 50-100m. Open the inter-rail passage door 13 to enter the space from the inter-rail passage 5 to the top plate of the under-rail structure 9, which not only meets the operation requirements of the vacuum pipeline ultra-high-speed maglev train, but also forms a stable and convenient evacuation or maintenance passage in a vacuum environment. To facilitate the evacuation of personnel in the platform safety space 6 and enter the space between the inter-rail passage 5 and the top plate of the under-rail structure 9; the side walls of the inter-rail passage 5 are respectively provided with inter-rail passage side wall doors 14 for personnel to enter from the under-rail structure. 9 The top surface is directly evacuated or overhauled.

Abstract

The invention discloses an internal structure of a maglev vacuum pipeline. A through under-rail structure is arranged at the inner bottom of the pipeline body structure in the length direction of thepipeline body structure, an inter-rail channel and maglev rails located on the two sides of the inter-rail channel are arranged at the top of the under-rail structure, an ultra-high-speed maglev traincan run on the maglev rails in a two-way mode, and the operation space of the maglev rails is a vacuum environment. The inter-rail channel is of a closed structure and is arranged in a penetrating mode along the pipeline body structure, the upper portion of the inter-rail channel is provided with a platform safety space meeting the train driving requirement, the inter-rail channel can enter the inter-rail channel through the inter-rail channel stairs and the inter-rail channel doors to the top face of the under-rail structure, and the inter-rail channel side wall doors are arranged on the twoside walls of the inter-rail channel according to requirements. Space requirements of a train form, evacuation or maintenance and equipment arrangement are comprehensively planned through the internal structure of the pipeline, the section space of the pipeline is effectively utilized, the pipeline is suitable for a single-pipe double-line form, compared with a double-pipe single-line form, the construction cost is reduced, the evacuation and maintenance functions are perfected, and the equipment space is reasonably configured.

Description

technical field [0001] The invention relates to the technical field of vacuum pipeline ultra-high-speed maglev transportation, in particular to an internal structure of a maglev vacuum pipeline. Background technique [0002] In the process of exploring higher-speed transportation systems, vacuum tube ultra-high-speed maglev transportation has attracted the attention of scientific and technological workers in many countries, and many experimental studies have been carried out. This technology requires the construction of a pipeline structure for the train to draw out the air in the pipeline to form a vacuum environment with a low degree of vacuum to reduce the running resistance of the train. With the characteristics of ultra-high speed, it is expected to operate at a speed close to or even exceed 600km / h. In consideration of cost, the current research on maglev vacuum pipelines is mostly focused on single-tube single-line pipelines with small diameters, and insufficient res...
