Description

Technical Field

[0001] The invention relates to the technical field of rail transit, and in particular to a guide-adjustable sidewall magnetic suspension module installation interface and a fine-tuning method. Background Art

[0002] The superconducting electric suspension electromagnetic propulsion system has the advantages of large thrust, high efficiency, and high floating resistance ratio, and has broad application prospects in the field of high-speed and ultra-high-speed rail transportation. In order to ensure the stability of suspension and vehicle safety, the electric suspension track generally adopts a U-shaped topology, and the electric suspension and linear motor ground modules are installed on the side wall of the track and installed and laid continuously. The superconducting electric suspension system has high requirements for the installation accuracy of the ground module, especially the installation accuracy in the guiding direction. The unevenness of the track will cause the electromagnetic force fluctuation of the electric suspension system, thereby affecting the stability of the suspension guidance. The sidewall-mounted ground module generally reserves a large radial gap between the fastening bolts and the module installation hole to provide a large vertical, longitudinal and other plane position adjustment margin for the module body to perform secondary compensation adjustment for the installation accuracy error of the prefabricated plate, so as to achieve smooth installation in the plane direction, but it is impossible to adjust relative to the prefabricated plate in the guiding or thickness direction, especially at the junction of the two ground modules of adjacent prefabricated plates, which are prone to large uneven guiding installation due to the overall installation deviation of the prefabricated plate, affecting the stability of the suspension guidance of the aircraft.

[0003] The most commonly used side wall type ground module installation interface is to fine-tune the entire high-precision concrete precast panel into place on the directly cast U-shaped track beam through the fine-tuning frame, and then use self-compacting concrete to fill the gap between the precast panel and the U-shaped track beam and fix the precast panel. After that, the precast panel itself cannot be adjusted. Then the ground module is directly installed on the precast panel. Another installation method is to use anchor plates and bolts and other fasteners instead of self-compacting concrete to achieve an overall adjustable fixation between the precast panel and the track, and then directly install the ground module on this basis.

[0004] However, both existing installation methods aim to fine-tune the entire precast concrete panel into place. Due to the large size and weight of a single precast panel, the volume and rigidity of the fine-tuning equipment required for millimeter-level fine-tuning are extremely high, and the fine-tuning efficiency is low. In addition, during the storage process after prefabrication, the plate-type concrete precast panel will cause bending deformation of the entire panel due to its own gravity and internal stress, especially in the thickness direction where the rigidity is weakest. In addition, during the pouring of self-compacting concrete, the solidification and expansion of the concrete will also cause deformation in the thickness direction of the precast panel. This deformation is uncontrollable and cannot be compensated by the above overall fine-tuning, which will cause obvious lateral precision deviations in the ground module directly installed on the precast panel. Summary of the invention

[0005] The present invention provides a guide-adjustable sidewall magnetic suspension module installation interface and a fine-tuning method, which can solve the technical problem that the traditional construction method can only perform high-precision adjustment on the entire prefabricated panel but cannot compensate for the local unevenness caused by the deformation of the panel itself.

[0014] An average value of the compensation error of each embedded bolt sleeve is obtained, and the average value of the compensation error of each embedded bolt sleeve is used as the axial distance between the support surface and the positioning reference surface.

[0015] Preferably, the measurement coordinates of each embedded bolt sleeve are obtained by a laser total station or a tracker.

[0016] Preferably, the axial distance between the support surface and the positioning reference surface is measured by a depth gauge.

[0017] Preferably, an adjustment drive interface is provided inside the second end of the adjustable adapter sleeve.

[0018] Preferably, the adjustment drive interface is a polygonal structure.

[0019] Preferably, the outer diameter of the supporting surface of the adjustable adapter sleeve is larger than the diameter of the mounting hole of the motor module.

[0020] According to another aspect of the present invention, a method for fine-tuning a guide-adjustable sidewall magnetic suspension module installation interface is provided, wherein the method uses any of the above-mentioned installation interfaces to guide and adjust the prefabricated panel, and the method comprises:
