The working principle is as follows:
the upper seat plate 14 of the magnetic suspension support is fixed on a vacuum pipeline of the magnetic suspension system, and the lower seat plate 11 is fixed on a lower supporting structure of the magnetic suspension system, so that the function of connecting the lower supporting structure with the vacuum pipeline is achieved. When assembly errors occur in the construction and installation processes of a vacuum pipeline and a lower supporting structure of the magnetic suspension system or the relative positions of the vacuum pipeline and the lower supporting structure change in the subsequent use process due to temperature change and sedimentation deformation, the integrity and the smoothness of a magnetic suspension system line can be ensured by adaptively adjusting a magnetic suspension support, and the running safety of a train is ensured.
In particular, the relative position change of the vacuum duct and the lower support structure in the direction of the bridge can be accommodated by the relative sliding between the upper seat plate 14 and the middle seat plate 13; the relative positions of the vacuum pipeline and the lower supporting structure in the transverse bridge direction change, the positions of the two positioning sliders 121 in the transverse bridge direction can be adjusted to adapt by simultaneously rotating the two positioning bolts on the lower seat plate 11 in the same direction, the relative positions of the two positioning sliders 121 are kept unchanged in the process, the positions of the upper structures such as the middle seat plate 13 and the upper seat plate 14 in the transverse bridge direction change along with the position change of the two positioning sliders 121, and the height of the magnetic suspension support is unchanged in the process; the relative position of vacuum pipe and lower part bearing structure in vertical direction changes, the accessible rotates two positioning bolts on the bedplate 11 down along the equidirectional rotation simultaneously and carries out the adaptability adjustment to the magnetic suspension support, specifically, rotate two positioning bolts along the equidirectional rotation and can make two positioning sliders 121 be close to each other or keep away from along the horizontal bridge, when two positioning sliders 121 are close to each other, second inclined plane 133 on the well bedplate 13 and the first inclined plane 1213 on the positioning slider 121 take place relative slip, well bedplate 13 risees, the overall height of magnetic suspension support increases, when two positioning sliders 121 keep away from each other, second inclined plane 133 on the well bedplate 13 and the first inclined plane 1213 on the positioning slider 121 take place relative slip, well bedplate 13 reduces, the overall height of magnetic suspension support reduces.
The cylindrical plate 19 of the magnetic suspension support is matched with the arc-shaped groove 132, so that the upper seat plate 14 can vertically rotate along the bridge direction, and meanwhile, the torque of the upper seat plate 14 in other directions can be borne, so that the upper seat plate 14 is limited to rotate in other directions, and the vacuum pipeline is prevented from generating plane torsion. The rotating sleeve 18 is arranged between the upper seat plate 14 and the middle seat plate 13, so that the relative sliding and the relative rotation between the upper seat plate 14 and the middle seat plate 13 are divided into the relative sliding between the upper seat plate 14 and the rotating sleeve 18 and the relative rotation between the rotating sleeve 18 and the middle seat plate 13, the rotation and the sliding of the upper seat plate 14 are not influenced by each other, and the loads such as the vertical tension of the upper seat plate 14 and the horizontal force along the transverse bridge direction can be accurately transmitted to a lower structure; meanwhile, the transfer of force is not influenced in the positioning process, so that the driving safety of the magnetic suspension support during positioning is ensured.
Second embodiment
As shown in fig. 14, the present embodiment provides a magnetic suspension support, the structure of the magnetic suspension support of the present embodiment is substantially the same as that of the first embodiment, except that the magnetic suspension support of the present embodiment further includes upper seat plate barrier strips 27, two upper seat plate barrier strips 27 are respectively fixed at two ends of the upper seat plate 14 in the bridge direction, one surface of the upper seat plate barrier strip 27 is tightly attached to the rotating sleeve 18, so that the rotating sleeve 18 and the upper seat plate 14 cannot move relatively in the bridge direction, and further the lower seat plate 11 and the upper seat plate 14 do not move relatively in the bridge direction, which enables the load of the vacuum pipeline of the magnetic suspension system on the upper seat plate 14 in the bridge direction to be accurately transferred to the lower seat plate 11, thereby effectively limiting the position change of the vacuum pipeline of the magnetic suspension system in the bridge direction. The magnetic suspension support in the embodiment is suitable for occasions with strict requirements on the position of a vacuum pipeline of a magnetic suspension system along the bridge direction.
