Adjustable support of magnetic levitation track

Abstract

The invention discloses an adjustable support of a magnetic levitation track. The adjustable support comprises a support plate and two jacking parts, the support plate is used for being connected between a track beam and a spandrel girder, wherein the two jacking parts are arranged below the support plate, the two jacking parts are arranged on the two opposite sides of the support plate respectively, and each jacking part is used for enabling the corresponding side of the support plate to ascend or descend so as to enable the two sides of the track beam in the width direction to ascend or descend respectively. According to the device, a two-stage adjusting mechanism is adopted to effectively adjust the installation precision and the use precision of the single-section track beam; the processing and mounting precision of the bearing beam and the lower structure is reduced; the installation difficulty and cost are reduced, the adjustment requirements of the track beam in various application scenes are effectively met, standardization and unification of track beam design are facilitated, the running speed and riding comfort of a magnetic levitation line are guaranteed in the running process, the reliability of a magnetic levitation track is improved, and the magnetic levitation track has great significance in high-speed magnetic levitation running in China.

Description

technical field [0001] The invention relates to the technical field of a magnetic levitation track support, in particular to an adjustable support of a magnetic levitation track. Background technique [0002] In order to ensure the safety and comfort of trains running at high speeds, the high-speed maglev train system (for example, with a speed exceeding 400 km per hour) puts forward high design and manufacturing requirements for the track. For example, in terms of structural rigidity, it is required that the mid-span deflection of a single-span simply supported track beam under the static vehicle action is less than L / 4800 (L is the span of a simply supported beam), which is much higher than the L / 600~L / 800 required by roads and railways . In addition, the manufacturing and installation accuracy of the three functional surfaces of the track is also required to be controlled within 1mm. These design requirements directly depend on the track structure and later commissionin...

Problems solved by technology

[0004] The purpose of the present invention is to overcome that the accuracy of the existing maglev track beam is guaranteed by the adjustment support under the lower support structure, which not only makes the design and processing difficult, but also increases the cost, and the installation accuracy control requirements are high, which cannot meet the accuracy adjustment requirements of the operation stage and The above-mentioned deficiencies such as the precision adjustment requirements of the single-section track beam provide an adjustable support for the maglev track
