Description

Split type double-pipe double-line vacuum pipeline structure and magnetic suspension high-speed train using same

Technical Field

The invention relates to the technical field of vacuum pipeline traffic systems, in particular to a split type double-pipe double-line vacuum pipeline structure and a magnetic suspension high-speed train using the same.

Background

For mass transportation vehicles running at high speed, no matter an airplane or a high-speed rail, the main running resistance of the vehicles is air resistance, the air resistance limits the speed increase, and huge energy consumption is formed.

At present, the vacuum pipeline transportation does not enter the engineering implementation and application stage worldwide, and from the technical solutions disclosed in the related information at home and abroad, the conventional common double-line pipeline structure is specifically shown in fig. 5 to 8, wherein fig. 5 and 6 show the structure of a vertically arranged double-line vacuum pipeline, and fig. 7 and 8 show the structure of a horizontally arranged double-line vacuum pipeline. The cross section shapes of the two types of double-line vacuum pipelines are both two complete circular pipe structures, the basic structural characteristic of each large circular pipe is that a sealed and closed space is formed by adopting the whole circular pipe structure, and a track is built at the bottom of the circular pipe, and the two types of double-line vacuum pipelines are particularly shown in figure 9. However, the two-wire pipe in the prior art has the following disadvantages in use.

First, the large circular pipes forming the two pipelines in the prior art can only share the bridge pier, and the bridge part cannot share the bridge pier, so that the construction cost of only part of the bridge pier can be saved compared with two single lines.

Second, the strength properties of concrete materials and steel are not fully exploited for each pipe. The action load on the pipeline when a vehicle runs in the vacuum pipeline is mainly vertical, so that the section of the pipeline is required to have high bending rigidity in the vertical direction, the horizontal direction does not need too high rigidity, and the bending capacities of the whole circular steel pipe in the vertical direction and the horizontal direction are the same and unreasonable. In addition, the section geometry of the concrete part cannot be designed too high due to the limitation of the round pipe, more materials are distributed in the horizontal direction, the vertical rigidity of the pipeline is insufficient, the horizontal rigidity is excessive, and the strength performance of the materials is not fully utilized.

Thirdly, construction at elevated bridge sections is difficult. The vacuum pipeline is made into a section with the length of dozens of meters when in use, the vacuum pipeline is installed on a viaduct by using bridging equipment, the upper side of the pipeline of the whole circular pipe structure is arc-shaped, only one layer of steel plate is arranged, the dead weight of a bridge girder erection machine cannot be borne, particularly the double-line pipeline form which is vertically arranged is more difficult to construct, and the construction cost is high as a result of the great difficulty in engineering construction.

Fourth, the line footprint of a two-wire pipeline construction is large. Particularly for the double-line pipeline form arranged horizontally, because the transverse and vertical dimensions of each large circular pipe are the same, in order to increase the bending vertical rigidity, the diameter of the circular pipe must be increased, and the increase of the transverse dimension increases the floor area of the vacuum pipeline circuit, thereby increasing the line construction cost.

In the description of the present invention, it is to be understood that the orientation or positional relationship indicated by the orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, horizontal" and "top, bottom", etc. are usually based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplicity of description, and in the case of not making a reverse description, these orientation words do not indicate and imply that the device or element being referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore, should not be considered as limiting the scope of the present invention; the terms "inner and outer" refer to the inner and outer relative to the profile of the respective component itself.

Spatially relative terms, such as "above … …," "above … …," "above … …," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial relationship to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in the figures is turned over, devices described as "above" or "on" other devices or configurations would then be oriented "below" or "under" the other devices or configurations. Thus, the exemplary term "above … …" can include both an orientation of "above … …" and "below … …". The device may be otherwise variously oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

It should be noted that the terms "first", "second", and the like are used to define the components, and are only used for convenience of distinguishing the corresponding components, and the terms have no special meanings unless otherwise stated, and therefore, the scope of the present invention should not be construed as being limited.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
