DETAILED DESCRIPTION

[0030] The present invention is further described in detail below in conjunction with examples, but the embodiments of the present invention are not limited thereto.

[0031] Embodiment 1:

[0032] like Figure 1 As shown, in this embodiment, a finishing system for positioning a magnetic levitation track beam includes an adjustable bottom support structure arranged below the left track 6 and the right track 14, an adjustable outer support structure arranged outside the left track 6 and the right track 14, and an adjustable middle support structure arranged between the left track 6 and the right track 14.

[0033] This solution utilizes a bottom support structure to support the left rail 6 and the right rail 14 from the bottom, utilizes an outer support structure to support the left rail 6 and the right rail 14 from the outside, and utilizes an intermediate support structure to support the inner side of the left rail 6 and the right rail 14 and to be parallel to the force applied by the outer support structure to maintain the stability of the left rail 6 and the right rail 14.

[0034] This solution can adjust and position the left rail 6 and the right rail 14 through the bottom support structure, the outer support structure and the middle support structure, and can keep the left rail 6 and the right rail 14 stable during the adjustment process, avoiding the left rail 6 and the right rail 14 from being affected by external forces and causing the position to change, and has the advantage of high positioning accuracy. In the process of adjusting the position of the left rail 6 and the right rail 14, there is no need to use a crane to continuously suspend the left rail 6 and the right rail 14, which can reduce construction costs and construction difficulties.

[0035] Embodiment 2:

[0036] On the basis of the above-mentioned embodiment, in this embodiment, the bottom supporting structure includes a plurality of bottom adjusting jacks 3 respectively arranged under the left rail 6 and under the right rail 14 .

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

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

[0039] In this embodiment, the bottom adjustment jacks 3 are evenly distributed along the length direction of the left rail 6 or the right rail 14. The left rail 6 or the right rail 14 has a certain length. By providing a plurality of bottom adjustment jacks 3 to support the left rail 6 or the right rail 14, the left rail 6 or the right rail 14 can be adjusted from multiple locations to avoid the left rail 6 or the right rail 14 from tilting due to poor span.

[0040] Embodiment 3:

[0041] On the basis of the above embodiments, in this embodiment, the outer supporting structure includes a plurality of groups of outer supporting devices arranged on the outer sides of the left rail 6 and the right rail 14 along the length direction of the left rail 6, and the outer supporting devices include two jack pedestals 4 symmetrically arranged on the outer sides of the left rail 6 and the right rail 14 and a side adjustment jack 5 arranged on the jack pedestals 4.

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

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

[0044] The higher side adjustment jack 5 is used to mainly adjust the angle of the left track 6 or the right track 14. The side adjustment jack 5 applies thrust to the left track 6 or the right track 14, making it convenient for the left track 6 or the right track 14 to rotate with the bottom adjustment jack 3 as the fulcrum, thereby facilitating the adjustment of the angle.

[0045] The lower side adjustment jack 5 is mainly used to adjust the distance between the left rail 6 and the right rail 14. Since the lower side adjustment jack 5 is closer to the bottom adjustment jack 3, when the lower side adjustment jack 5 applies thrust to the left rail 6 and the right rail 14, it is beneficial to drive the left rail 6 and the right rail 14 to move as a whole, thereby facilitating the adjustment of the distance between the left rail 6 and the right rail 14.

[0046] like Figure 4 As shown, the output shaft 51 of the side adjustment jack 5 is provided with a thread, and a locking nut 52 is threadedly connected to the output shaft 51. When the output shaft 51 of the side adjustment jack 5 extends outward, the output shaft 51 of the side adjustment jack 5 applies thrust to the left track 6 or the right track 14 until the position of the left track 6 or the right track 14 meets the construction requirements. At this time, the locking nut 52 is rotated until the locking nut 52 contacts the cylinder body of the side adjustment jack 5. At this time, due to the self-locking function of the thread, the output shaft 51 can be prevented from retracting, which causes the position accuracy of the left track 6 or the right track 14 to change, which is conducive to improving the positioning accuracy of the left track 6 or the right track 14.

[0047] The free end of the output shaft 51 is provided with a side support block 53 whose cross-sectional area is larger than that of the output shaft 51. The side support block 53 can increase the contact area between the output shaft 51 and the left rail 6 or the right rail 14 of the output shaft 51, thereby reducing the pressure per unit area within the pressure range of the left rail 6 or the right rail 14, thereby avoiding the pressure exerted by the output shaft 51 on the left rail 6 or the right rail 14 causing surface damage to the left rail 6 or the right rail 14.

[0048] In this embodiment, the jack base 4 adopts a triangular frame structure, which is beneficial to ensure the strength and rigidity of the jack base 4 itself, and avoid the reaction force exerted by the side adjustment jack 5 on the jack base 4 causing the jack base 4 to deform and affect the position accuracy of the side adjustment jack 5.

[0049] The side adjustment jack 5 can be used to achieve a fine-tuning function, which is beneficial to improving the positioning accuracy of the left rail 6 and the right rail 14.

[0050] Embodiment 3:

[0051] On the basis of the above embodiments, in this embodiment, the intermediate support structure includes a vertical bracket 1, a transverse bracket arranged on the vertical bracket 1, and a retractable bracket 9 arranged at both ends of the transverse bracket 2, and the retractable bracket 9 is respectively connected to the corresponding left rail 6 or right rail 14 in a transmission manner.

[0052] The middle support structure is used to support the inner sides of the left rail 6 and the right rail 14 at the same time, and can balance the thrust applied by the side adjustment jack 5 to the left rail 6 or the right rail 14, preventing the left rail 6 or the right rail 14 from tipping inward, and helping to maintain the stability of the left rail 6 or the right rail 14.

[0053] By applying a thrust to the left rail 6 or the right rail 14 through the intermediate support structure, the left rail 6 or the right rail 14 can be rotated or moved outward, thereby adjusting the angle or position.

[0054] In this embodiment, the vertical bracket 1 and the horizontal bracket 2 are used as the main body to maintain stability, and the telescopic bracket 9 is used to apply thrust to the left track 6 or the right track 14. The telescopic length of the telescopic bracket 9 is used to control the rotation angle or movement distance of the left track 6 or the right track 14.

[0055] In this embodiment, two transverse brackets 2 are provided, wherein the retractable bracket 9 on one transverse bracket 2 is respectively connected to the upper part of the left rail 6 or the right rail 14 for transmission, and the retractable bracket 9 on the other transverse bracket 2 is respectively connected to the lower part of the left rail 6 or the right rail 14 for transmission.

[0056] The telescopic bracket 9 at a higher position is used to conveniently adjust the angle of the left track 6 or the right track 14. The telescopic bracket 9 at a lower position is used to conveniently adjust the left track 6 or the right track 14 to move inwards or outwards.

[0057] In this embodiment, two vertical brackets 1 are also provided to improve the stability of the intermediate support structure itself. A cross-shaped diagonal brace can also be provided between the two vertical brackets 1 to improve the strength and rigidity of the intermediate support structure and prevent the intermediate support structure from being deformed under the reaction force of the telescopic bracket 9, thereby causing the position accuracy of the telescopic bracket 9 to deteriorate.

[0058] In this embodiment, the retractable brackets 9 at both ends of the transverse bracket 2 are made of two threaded rods with opposite thread directions. The retractable brackets 9 are threadedly connected to the transverse bracket 2 , and the transverse bracket 2 is rotatably arranged on the vertical bracket 1 .

[0059] By rotating the transverse bracket 2, the retractable brackets 9 at both ends of the transverse bracket 2 can be controlled to rotate in or out synchronously, so that the left track 6 and the right track 14 can be adjusted synchronously, which is beneficial to keep the left track 6 and the right track 14 in a symmetrical positional relationship.

[0060] The free end of the retractable bracket 9 is provided with a support block 8. The contact area between the support block 8 and the left rail 6 or the support block 8 and the right rail 14 is larger than the cross-sectional area of ​​the retractable bracket 9, thereby increasing the friction between the retractable bracket 9 and the left rail 6 or the retractable bracket 9 and the right rail 14, avoiding relative movement between the retractable bracket 9 and the left rail 6 or the retractable bracket 9 and the right rail 14, and reducing the pressure per unit area within the supported range of the left rail 6 or the right rail 14, thereby avoiding the retractable bracket 9 from damaging the surface of the left rail 6 or the right rail 14. At the same time, it is also convenient to observe whether there is an angle between the support block 8 and the left rail 6 or the support block 8 and the right rail 14, so as to facilitate the judgment of whether the left rail 6 or the right rail 14 is tilted.

[0061] Embodiment 4:

[0062] like Figure 2 As shown, on the basis of the above embodiments, in this embodiment, the upper surfaces of the left rail 6 and the right rail 14 are respectively provided with at least one row of distance holes 15 arranged along the length direction of the left rail 6, and the left rail 6 and the right rail 14 are provided with distance devices, and the distance devices include a distance beam 10, two distance blocks 7 arranged on the distance beam 10, and distance nails 11 arranged on the distance blocks 7 and capable of being installed in conjunction with the distance holes 15.

[0063] Taking the distance between the two distance nails 11 as a reference standard, when the distance between the corresponding distance holes 15 on the left rail 6 and the right rail 14 is equal to the distance between the two distance nails 11, it is confirmed that the positions of the left rail 6 and the right rail 14 meet the use requirements.

[0064] After the left rail 6 and the right rail 14 are positioned through the adjustment of the bottom support structure, the outer support structure and the middle support structure, a distance device is used to detect each hole to ensure that the positions of the left rail 6 and the right rail 14 meet the construction requirements.

[0065] like Figure 3 As shown, one of the distance blocks 7 is slidably arranged on the distance beam 10, and the sliding direction of the distance block 7 is parallel to the length direction of the distance beam 10. In this embodiment, the distance beam 10 is provided with an adjustment track 13 parallel to the length direction of the distance beam 10. The distance block 7 can slide by slidingly connecting the distance block 7 with the adjustment track 13. The distance beam 10 is also provided with a scale 12, which includes a 0 scale. With the 0 scale as a reference standard, when the distance nail 11 points to the 0 scale, it is determined that the positions of the left track 6 and the right track 14 meet the construction requirements.

[0066] Graduation lines are arranged on both sides of the 0 scale. When the distance nails 11 point to either side of the 0 scale when the two corresponding distance holes 15 are detected, it is determined that the positions of the left track 6 and the right track 14 do not meet the construction requirements.

[0067] If the distance spike 11 points to the inside of the 0 scale, it means that one or both of the left track 6 and the right track 14 are tilted or translated inwardly beyond the requirement, so that corresponding adjustments can be made according to the scale line pointed by the distance spike 11.

[0068] Correspondingly, if the distance spike 11 points to the outside of 0, it means that one or both of the left track 6 and the right track 14 are tilted or translated outward beyond the requirement, so that corresponding adjustments can be made according to the scale line pointed by the distance spike 11.

[0069] During detection, the left track 6 and the right track 14 corresponding to the distance blocks 7 fixedly arranged on the distance beam 10 can also be used as reference standards. When a deviation is detected, the difficulty of adjustment can be reduced by adjusting the other track.

[0070] In this embodiment, other contents not described are the same as those in the above embodiment, and thus will not be described in detail.

[0071] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent change made to the above embodiment based on the technical essence of the present invention shall fall within the protection scope of the present invention.
