Embodiment 1

[0032] Such as figure 1 As shown, in this embodiment, a hardcover system for the positioning of the magnetic levitation track beam includes an adjustable bottom support structure arranged under the left rail 6 and the right rail 14, and an adjustable bottom support structure arranged on the outside of the left rail 6 and the right rail 14. An adjustable outer support structure and an adjustable middle support structure arranged between the left track 6 and the right track 14 .

[0033] This scheme uses the bottom support structure to support from the bottom of the left track 6 and the right track 14, uses the outer support structure to support from the outside of the left track 6 and the right track 14, and uses the middle support structure to support the inner side of the left track 6 and the right track 14. Supporting and parallel to the force exerted by the outer support structure to maintain the stability of the left track 6 and the right track 14 .

[0034] This solution...

Embodiment 2

[0036] On the basis of the above embodiments, in this embodiment, the bottom support structure includes several bottom adjustment jacks 3 respectively arranged under the left rail 6 and the right rail 14 .

[0037] The jack can provide the required thrust so as to adjust the height of the left rail 6 and the right rail 14, thereby ensuring that the bottom surfaces of the left rail 6 and the right rail 14 remain level. The jack also has the function of maintaining the pressure. After the adjustment is completed, the positions of the left track 6 and the right track 14 will not change, which is conducive to maintaining the positioning accuracy of the left track 6 and the right track 14.

[0038] The jack can also realize the function of fine-tuning to meet the requirement of adjusting the height of the left track 6 or the right track 14 in a small range, which is conducive to improving the positioning accuracy.

[0039] In this embodiment, the bottom adjustment jacks 3 are evenl...

Embodiment 3

[0041] On the basis of the above embodiments, in this embodiment, the outer support structure includes several groups of outer support devices arranged outside the left track 6 and the right track 14 along the length direction of the left track 6, and the outer support devices include two A jack pedestal 4 that is symmetrically arranged on the left rail 6 and the right rail 14 outsides and a side adjustment jack 5 that is arranged on the jack pedestal 4.

[0042] This program can utilize the side adjustment jack 5 to apply thrust from the outside of the left rail 6 or the right rail 14 to adjust the angle of the left rail 6 or the right rail 14, or adjust the distance between the left rail 6 and the right rail 14.

[0043] In this embodiment, the jack stand 4 is provided with two side adjustment jacks 5 distributed along the vertical direction.

[0044] The side adjustment jack 5 with a higher position is used to mainly adjust the angle of the left track 6 or the right track 1...

Abstract

The invention discloses a hardcover system for positioning a magnetic suspension track beam. The hardcover system comprises an adjustable bottom supporting structure arranged below a left track and a right track, an adjustable outer side supporting structure arranged on the outer side of the left track and the outer side of the right track, and an adjustable middle supporting structure arranged between the left track and the right track. The invention has the beneficial effects that the scheme can support the left track and the right track from multiple directions to achieve a positioning effect, repeated adjustment of the left track and the right track in the hoisting process is avoided, the positioning difficulty can be effectively reduced, the positioning efficiency can be improved, the positioning precision can be improved, and therefore, the construction period can be shortened.

Description

technical field [0001] The invention relates to the technical field of magnetic levitation track beams, in particular to a hardcover system for positioning magnetic levitation track beams. Background technique [0002] The track beam of the embedded magnetic levitation track has a "concave" shape as a whole, and its cross-section has a left-right symmetrical structure. Most of the structure of the track beam is prefabricated in the factory, including the left track and the right track. During construction, it is necessary to use reinforced concrete pouring to connect the left track and the right track to form a complete track beam. [0003] Under the existing technical conditions, gantry hoisting is usually used, and the left track and the right track are hoisted and placed side by side on the same pedestal. During the hoisting process, the positions of the left track and the right track need to be adjusted to ensure The position accuracy of the right track meets the requi...
