Description

Technical Field

[0001] The utility model relates to the field of magnetic levitation tracks, in particular to an assembled 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.

[0003] In the prior art, the track beam of the maglev track is generally equipped with a group of large magnet modules inside, which are used to provide the vehicle above with forward driving force and lift required for suspension at the same time; this maglev method has the problem 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 test section tracks to carry out a large number of engineering tests and verifications; however, the existing maglev track beam construction project is large in volume and takes a long time to construct, and the maglev track beam cannot be dismantled for secondary use after engineering tests and verifications. Utility Model Content

[0004] The utility model provides an assembled maglev track beam to solve the problems in the prior art that the maglev track beam is too large in size, very difficult to manufacture and install, has a large construction workload, and takes a long construction time.

[0005] To achieve the above purpose, the utility model provides the following solutions:

[0006] An assembled maglev track beam comprises a base and a propulsion groove and a suspension groove located above the base, and also comprises two first prefabricated beams and two second prefabricated beams located between the two first prefabricated beams, the propulsion groove is formed between the two second prefabricated beams, the suspension groove is formed between the first prefabricated beam and the second prefabricated beam located on the same side of the propulsion groove, and the first prefabricated beam and the second prefabricated beam both comprise a plurality of sections of sub-prefabricated beams spliced ​​to each other.

[0007] The utility model divides the maglev track beam into several sections of sub-prefabricated beams which are spliced ​​with each other. The prefabricated beams are transported to the installation site for installation after being prefabricated in the factory. The prefabricated maglev track beams can be prepared before construction, which can effectively reduce the construction period. The sub-prefabricated beams which are spliced ​​with each other can artificially control the length and weight of each section of the sub-prefabricated beams, which is convenient for transportation and installation. Moreover, due to the splicing characteristics, the dismantling is relatively convenient. The maglev track beams can be dismantled for secondary use after relevant engineering tests and verifications, which reduces waste.

[0008] Furthermore, the second prefabricated beam includes a plurality of base beams and a first connecting beam, wherein the lower end of the base beam is connected to the base, and the lower end of one of the first connecting beams is connected to the upper ends of at least two of the base beams. By connecting more than two base beams through one first connecting beam, the overall structure of the second prefabricated beam is more solid, and the connection degree between two adjacent base beams is increased.

[0009] Furthermore, the base beam is provided with a plurality of first connection parts on one side of the propulsion groove, and the base beams on both sides of the propulsion groove are connected through the first connection parts, thereby increasing the reliability of the connection of the base beams on both sides of the propulsion groove.

[0010] Furthermore, the second prefabricated beam further comprises a plurality of connecting plates mounted on the side walls of the advancement groove, the width of the connecting plates being greater than the width of the first connecting beam, and the connecting plates being connected to the base beam and the first connecting beam, thereby increasing the reliability of the connection between the base beam and the first connecting beam.

[0011] Furthermore, the first prefabricated beam comprises a second connecting beam installed on the base and a limiting beam installed on the upper end of the second connecting beam. By dividing the first prefabricated beam into the second connecting beam and the limiting beam, the overall weight of the first prefabricated beam is reduced, which is convenient for production, transportation and installation.

[0012] Furthermore, the second connecting beam is provided with a plurality of second connecting parts on one side facing the suspension groove, and the second connecting parts are connected to the base beam. The second connecting beam is connected to the base beam through the second connecting parts, thereby increasing the stability of the second connecting parts and the base beam.

[0013] Furthermore, the length of the second connecting beam is greater than the length of the base beam. By connecting at least two base beams through a second connecting beam, the stability of the connection between two adjacent base beams is increased.

[0014] Furthermore, one base beam is connected to at least two of the first connection parts and two of the second connection parts. The first connection parts and the second connection parts increase the stability of the installation of the single base beam and enhance its connection strength.

[0015] Furthermore, a plurality of first protrusions are provided on the upper end of the base, a plurality of grooves are provided on the upper and lower ends of the base beam and the second connecting beam, a plurality of second protrusions are provided on the lower ends of the first connecting beam and the limiting beam, the grooves at the lower ends of the base beam and the second connecting beam match the first protrusions, and the grooves at the upper ends of the base beam and the second connecting beam match the second protrusions.

[0016] Since the maglev track beam is installed at an angle, under the influence of the component force of gravity, there is a tendency to move parallel to the direction of the maglev track between the base beam and the base, between the second connecting beam and the base, between the base beam and the first connecting beam, and between the second connecting beam and the limiting beam. This will increase the burden on the connecting parts between the sub-prefabricated beams and cause the connecting parts to break. Therefore, the resistance to lateral movement between the sub-prefabricated beams is increased by cooperating with a number of grooves and protrusions, thereby reducing the burden on the connecting parts and preventing the maglev track beam from being misaligned.

[0017] Furthermore, the grooves at the lower ends of the base beam and the second connecting beam correspond to the first protrusions one-to-one, and the grooves at the upper ends of the base beam and the second connecting beam correspond to the second protrusions one-to-one.

[0018] Furthermore, bolt holes are provided on the base and / or the sub-prefabricated beam, bolts are embedded in the bolt holes, and the sub-prefabricated beam connected to the base and the sub-prefabricated beam is provided with a nut groove and a screw hole provided on the side wall of the nut groove, and the bolt is connected to the nut in the nut groove after passing through the screw hole. By prefabricating the bolt holes and bolt holes on the sub-prefabricated beam, the connecting parts are located inside the base and the sub-prefabricated beam, preventing them from affecting the overall performance of the maglev track beam, and the installation is convenient.

[0019] One or more technical solutions provided by the utility model have at least the following technical effects or advantages:

[0020] (1) The utility model divides the maglev track beam into several sections of prefabricated sub-beams that are spliced ​​together. The prefabricated maglev track beams are prefabricated in a factory and then transported to the installation site for installation. The prefabricated maglev track beams can be prepared before construction, which can effectively reduce the construction period. The spliced ​​sub-prefabricated beams can manually control the length and weight of each section of the prefabricated sub-beams, which is convenient for transportation and installation. In addition, due to the splicing characteristics, the dismantling is relatively convenient. After the relevant engineering tests and verifications, the maglev track beams can be dismantled for secondary use, which reduces waste.

[0021] (2) By interlacing the base and the various prefabricated sub-beams, the stability of the connection between the various parts of the maglev track beam is increased. BRIEF DESCRIPTION OF THE DRAWINGS
