Description

Technical Field

[0001] The utility model relates to the field of magnetic levitation tracks, in particular to a magnetic levitation track beam. Background Art

[0002] The track beam is an important part of the maglev track. It is a beam or plate structure with a track functional surface, bearing the train load and transferring it to the supporting structure. In other words, the maglev track beam has the functions of both the beam and the track of a traditional railway. Compared with the operation of traditional rail trains, maglev trains have extremely high requirements for the accuracy of the track beam.

[0003] In the field of high-speed maglev, the distance between the train magnets and the magnets on the track beam directly affects the change in magnetic buoyancy. In order to ensure the smooth development of lift and resistance when the vehicle takes off and lands, and at the same time ensure the riding comfort of the vehicle in the middle section of the line, very strict requirements are placed on the construction accuracy of traditional maglev track beams, which makes it difficult for traditional cast-in-place construction technology to meet this accuracy requirement.

[0004] In the prior art, a track beam of a maglev track is generally equipped with a group of large magnet modules inside, which are used to provide forward driving force and lift required for suspension for the vehicle above at the same time; this maglev method has the disadvantages that the magnet module is too large and is very difficult to manufacture and install; in addition, with the continuous in-depth research on ultra-high-speed maglev track technology, the application of ultra-high-speed maglev technology has gradually begun to be considered in certain non-railway transportation fields, which requires the construction of a test section track to carry out a large number of engineering tests and verifications; however, the existing maglev track beam cannot be installed with the magnet module of the ultra-high-speed maglev technology, and is therefore not suitable for use in the test section track of ultra-high-speed maglev. Utility Model Content

[0005] The utility model aims to provide a magnetic levitation track beam to solve the problem that the magnetic levitation track beam in the prior art is not suitable for use in the test section track of ultra-high-speed magnetic levitation, and to achieve the purpose of providing a matching magnetic levitation track beam for the magnet module of the ultra-high-speed magnetic levitation technology.

[0006] The utility model is realized by the following technical solutions:

[0007] A magnetic levitation track beam comprises a lower foundation and a beam-track assembly located on the lower foundation, wherein the beam-track assembly comprises two first concrete components and two second concrete components located between the two first concrete components; the transverse side walls of the first concrete components and the transverse side walls of the second concrete components are parallel to each other.

[0008] The gap between the two second concrete components is a propulsion groove, and the gap between the first concrete component and the second concrete component located on the same side of the propulsion groove is a suspension groove.

[0009] In view of the problem that the maglev track beam in the prior art is not suitable for use in the test section track of ultra-high-speed maglev, the present application proposes a maglev track beam, the track beam structure includes a beam-rail assembly distributed up and down, and a lower foundation, wherein the beam-rail assembly is fixedly arranged on the lower foundation. In the present application, the lower foundation mainly plays the role of the middle "beam" of the track beam, and the beam-rail assembly mainly plays the role of the middle "rail" of the track beam.

[0010] The first concrete component is located on the lateral outer side of the beam-rail assembly, and the second concrete component is located in the middle position of the beam-rail assembly; the space between the two second concrete components forms the propulsion groove in the present application, which is used to install the propulsion magnet module therein; there is a group of first concrete components and second concrete components on the left and right sides of the propulsion groove, respectively, and the suspension groove in the present application is formed between the first concrete component and the second concrete component on the same side of the propulsion groove, which is used to install the suspension magnet module therein.

[0011] In the beam-track assembly, two suspension grooves are respectively located on both sides of the propulsion groove, and the suspension groove extends in the same direction as the propulsion groove. The propulsion groove is used to install the propulsion magnet module, and the suspension groove is used to install the suspension magnet module. Different installation spaces can be provided for magnet modules with different functions, which can solve the installation, use, and maintenance problems caused by the excessively large volume of the lower magnetic module in the existing maglev technology. By dividing the magnet modules in the track beam into a group of propulsion magnet modules and two groups of suspension magnet modules, it is adapted to the use of ultra-high-speed maglev track technology, especially suitable for the use of ultra-high-speed maglev test section tracks under certain special carrying conditions, and thus provides a matching maglev track beam for the magnet module of the ultra-high-speed maglev technology, filling the gap in the existing technology.

[0012] It should be noted that the propulsion magnet module and suspension magnet module recorded above are corresponding magnet modules designed and installed according to specific working conditions. Their specific structures are not limited in this application. They can be understood as magnet modules that have been adaptively adjusted to the shape, size or structure of the magnet module in conventional magnetic levitation technology. Their principles are the same as those of the magnet modules in conventional magnetic levitation technology. Their functions are to provide corresponding magnetic fields according to specific working conditions. Those skilled in the art can make adaptive designs according to specific working conditions.

[0013] The beam-rail assembly and the lower foundation in the present application can be made by cast-in-place or prefabrication, and the specific preparation method is not limited here.

[0014] In addition, the transverse direction in the present application refers to the direction perpendicular to the axial direction of the track beam in the horizontal direction.

[0015] Furthermore, the two first concrete components and the two second concrete components are symmetrically distributed relative to the axis of the advancement groove. The transverse outer side wall of the first concrete component is coplanar with the transverse outer side wall of the lower foundation; the transverse inner side wall of the second concrete component is coplanar with the groove wall of the advancement groove.

[0016] The lateral side walls of the track beam structure have a flat and continuous surface, and the groove walls of the thrust groove are also flat and continuous, thereby reducing the risk of obstruction that may be encountered when the maglev track beam is positioned and installed.

[0017] Furthermore, the top of the second concrete member is arranged in a stepped shape which gradually decreases toward the lateral outer side, so that the shape is convenient for cooperating with the upper carrier and at the same time ensures the lateral stability of the carrier when running at ultra-high speed.

[0018] Furthermore, the top surface of the second concrete component has a first step surface and a second step surface located in the transverse outer side of the first step surface, and the first step surface is higher than the second step surface. This structure facilitates cooperation with the carrier and further ensures the lateral stability of the carrier during ultra-high-speed operation.

[0019] Furthermore, the bottom of the suspension tank is a widening area, the top of the widening area is connected to the bottom of the suspension tank, and the widening area includes a widening portion whose lateral width gradually increases from top to bottom.

[0020] This solution sets a widening area at the bottom of the suspension tank, which can better meet the installation requirements of the suspension magnet module; at the same time, since the depth of the suspension tank is relatively small, the existence of the widening area can reduce the interference of debris, accumulated water, etc. that may appear inside the suspension tank on the suspension magnet module.

[0021] Furthermore, a deepening groove is provided on the top surface of the lower foundation, the long axis of the deepening groove is parallel to the axis of the advancement groove, and the top end of the deepening groove is connected to the bottom end of the advancement groove.

[0022] The deepening groove in this scheme can be understood as making the bottom of the propulsion groove located on the top surface of the lower foundation, and then deepening the propulsion groove downward, and the deepened area is completely located on the lower foundation. The purpose of this scheme to deepen the propulsion groove through the lower foundation is to consider that the propulsion magnet module needs to provide a larger magnetic force required for propulsion for ultra-high-speed maglev technology, so its volume will be larger than the suspension magnet module. Therefore, by deepening the propulsion groove, it is easier to install the propulsion magnet module, and at the same time, a deeper margin is reserved to reduce the interference of possible debris, water accumulation, etc. on the propulsion magnet module.

[0023] Furthermore, the groove walls on both sides of the deepened groove are coplanar with the inner side walls of the two second concrete components, thereby improving the overall flatness of the advancement groove.

[0024] Furthermore, a plurality of first through holes distributed along the axial direction are formed at the bottom of the deepening groove, and a plurality of second through holes distributed along the axial direction are formed at the bottom of the suspension groove.

[0025] In this solution, the first through hole and the second through hole are both connected to the bottom surface of the lower foundation, which can effectively reduce the stress concentration phenomenon inside the lower foundation; at the same time, it is beneficial to ensure the balance of temperature, humidity, pressure, etc. inside and outside the propulsion groove and suspension groove, and is more conducive to the magnetic levitation test section track to simulate actual wilderness conditions.

[0026] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0027] 1. The utility model provides a magnetic levitation track beam, which can provide different installation spaces for magnet modules with different functions, and can solve the installation, use, maintenance and other problems caused by the excessively large volume of the lower magnetic module in the existing magnetic levitation technology.

[0028] 2. The utility model provides a magnetic levitation track beam that can be adapted to the use of ultra-high-speed magnetic levitation track technology, and is particularly suitable for use in ultra-high-speed magnetic levitation test section tracks under certain special transport conditions, thereby providing a matching magnetic levitation track beam for the magnet module of the ultra-high-speed magnetic levitation technology, filling the gap in the prior art.

[0029] 3. The utility model provides a magnetic levitation track beam, which can effectively reduce the stress concentration phenomenon of the track beam, and is conducive to ensuring the balance of temperature, humidity, pressure, etc. inside and outside, and is more conducive to the magnetic levitation test section track simulating actual wilderness conditions.
