Specific embodiment

Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other Embodiment shall fall within the protection scope of the present invention.

The object of the present invention is to provide a kind of magnetic-levitation novel section F rails, exist to solve the above-mentioned prior art The problem of, keep the anti-bending strength of the section F rail and non-deformability strong.

In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, with reference to the accompanying drawing and specific real Applying mode, the present invention is described in further detail.

The present invention provides a kind of magnetic-levitation novel section F rail, as Figure 1-Figure 4, including it is integrally formed U-shaped Portion 1 and extension 2, U-shaped portion 1 include bottom plate 101, open up that there are two symmetrically arranged bolts hole 3 on bottom plate 101；101 liang of bottom plate End is integrally formed and is connected with the first legs and feet plate 102 and the second legs and feet plate 103；Extension 2 is located at the first legs and feet plate 102 of U-shaped portion 1 On lateral wall；2 bottom of extension is provided with positioning surface 201, is opened up on positioning surface 201 there are two location hole 4, positioning surface 201 is solid Surely it is set on modularization track girder 5；The lateral wall of second legs and feet plate 103 is at 2 position of tendency extension from bottom to top Incline structure；Angle between the lateral wall and vertical direction of second legs and feet plate 103 is 2 °~15 °.

It is further preferred that the arc structure that extension 2 and 1 junction of U-shaped portion are radius 10mm.Extension 2 is far from U-shaped The side wall in portion 1 is incline structure, and tilt angle is identical as the tilt angle of the second legs and feet plate 103, inclined direction and the second legs and feet The inclined direction of plate 103 is opposite.The section overall width 400mm of the U-shaped portion and extension, total height 96mm；The height of U-shaped portion Degree is 96mm, and is 16mm with the difference in height of extension.First legs and feet plate 102 and the second legs and feet plate 103 far from bottom plate 101 one The width at end is 28.5mm；Bottom plate 101 with a thickness of 36mm, the horizontal length of bottom plate 101 is 224.5mm；Two bolts hole 3 Between horizontal distance be 100-120mm.The distance between two location holes 4 are 95-100mm.The inside of second legs and feet plate 103 The arc structure that wall and 101 junction of bottom plate are radius 10mm；The inner sidewall of first legs and feet plate 102 and 101 junction of bottom plate For the arc structure of radius 20mm.The inner sidewall of first legs and feet plate 102 and the second legs and feet plate 103 tilts inwardly, inclination angle Spend it is identical, it is contrary.Angle between the lateral wall and vertical direction of second legs and feet plate 103 is 7 ± 1 °.

The working principle of the invention is as shown in Figure 3 and Figure 4, and suspension rack 12 is connect by air spring 14 with compartment 13, when After being installed on the energization of electromagnet 6 on suspension rack 12, the magnetic line of force 10 can be in the very strong magnetic yoke 7 of magnetic permeability, internal polar plate 8, external polar plate 9 And it is formed into a loop between the rail of the section F.The pole orientation of the section electromagnet 6 and F rail is mutually drawn using N, S extremely attracting principle Closely, it is closing the distance to the suspension distance setting being set in advance and suspends apart from 5-10mm is generally, depending on the machining accuracy of the section F rail And installation accuracy.Due to F cross sectional rail be it is fixed with roadbed 11, so electromagnetic force can only electromagnet to the section F rail direction quilt It furthers, due to the factor of Design of Mechanical Structure, the suspension rack 12 being connected to electromagnet 6, compartment 13 also just have corresponding upward Movement.Compartment 13 entire so is just held up by electromagnetic force, forms the magnetic suspension that our the big daives life of a family are said.

Automatic centering leads when the section F rail of the invention also has the function of positioning to attachment rail simultaneously and vehicle is run To effect.

When the section F rail is installed, the positioning surface of the section F rail positioning surface corresponding to modularization track girder is close to, and by Fastener fastening is locked.Since the corresponding positioning surface of the positioning surface of the section F rail, bottom surface and modularization track girder, bottom surface are all Face is obtained by machining, respective machined surface flatness precision can be guaranteed.To ensure that working line The gauge of the section F rail and the upper plane of the section F rail be consistent, embody the convenience of very high installation accuracy and installation, And installation, adjustment difficulty is greatly reduced, installation effectiveness greatly improves, while also making railway maintenance workload and difficulty, maintenance Cost is greatly reduced.

The section F rail positioning surface and guiding schematic cross-section, two sides inside and outside the second legs and feet plate of the section F rail, be designed to A tilted angle, 2 °~15 ° of angular range, be best by mechanical model and 7 ° of mach Usability analysis.In this way By the magnetic line of force in rail the second legs and feet plate of the section F, just there is a horizontal component, this power makes the electromagnet of two sides all simultaneously Inward force is born, to reach the trend remained in track centre at runtime in the center of gravity of vehicle, has been reached certainly The purpose of centering.This is also one of an important factor for preventing vehicle derailing.Corresponding mechanical analysis such as Fig. 5 institute at second legs and feet plate Show.

Specific examples are applied in the present invention, and principle and implementation of the present invention are described, above embodiments Illustrate to be merely used to help understand method and its core concept of the invention；At the same time, for those skilled in the art, according to According to thought of the invention, there will be changes in the specific implementation manner and application range.In conclusion the content of the present specification It should not be construed as limiting the invention.
