Description

Technical Field

[0001] The present invention relates to a medium and low speed maglev transportation system, and particularly to a suspended maglev vehicle, a track and a maglev transportation system. Background Art

[0002] As Figure 1 shown, all existing operating medium and low speed maglev transportation systems adopt straddle-type vehicle solutions, which have large line floor areas and high construction costs, and are not suitable for application scenarios with scarce land resources and limited space. In addition, in this system, the track type of track beam a - rail sleeper b - F rail c is adopted. The F rail c and the induction plate d are located between the linear motor e and the electromagnet f. When the electromagnet f attracts the F rail c to move upward, the linear motor e also moves upward, and the air gap between the linear motor e and the induction plate d increases, which will reduce the traction efficiency of the linear motor e and increase the vehicle energy consumption. Therefore, there is an urgent need for a medium and low speed maglev transportation system with a small floor area, low construction cost and high traction speed.

[0003] The aerial rail transit has the characteristics of low construction cost and small land occupation, and there are already commercial application cases of suspended monorails in wheel-rail transportation. Compared with the wheel-rail aerial rail solution, the maglev aerial rail has the advantages of low maintenance cost, comfortable and stable ride, etc. At present, there are already multiple technical solutions for the maglev aerial rail, but these solutions have some problems such as complex suspension frame structures, inconvenient installation and maintenance, and insufficient installation space for on-vehicle equipment such as vehicle traction, auxiliary, and suspension.

[0004] In the prior art, the suspended maglev transportation track system, suspension frame system, maglev vehicle and maglev system disclosed in Chinese Patent CN109795332A have problems such as inconvenient maintenance of the linear motor and the electromagnet, and poor heat dissipation; the suspended frame and maglev vehicle system disclosed in Chinese Patent CN114312864A has problems such as insufficient installation space for on-vehicle equipment. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a suspended maglev vehicle, a track and a maglev transportation system to reduce the floor area of the medium and low speed maglev transportation system, lower the construction cost, and at the same time improve the traction efficiency of the maglev vehicle and reduce the energy consumption of the maglev vehicle, aiming at the deficiencies of the large floor area and high construction cost of the existing medium and low speed maglev transportation system lines.

[0006] To solve the above technical problems, the present invention adopts the following technical solutions:

The linear motors are installed on the longitudinal beams. One end of the traction pull rod is connected to the longitudinal beam, and the other end is connected to the vehicle body.

[0015] A further improvement of the above solution is that the traction pull rod is Z-shaped.

[0018] Based on the same inventive concept, the present invention also provides a maglev transportation system, which includes the above-mentioned suspended maglev vehicle and the above-mentioned track. The electromagnets are installed on the second flanges. The frame and the track are in a state of holding the rail, and the steel rail and the electromagnets are installed opposite to each other, and the induction plate and the linear motors are installed opposite to each other.

[0019] A further improvement of the above solution is that the steel rail, the electromagnets, the induction plate, the linear motors, the air springs, and the vehicle body moving platform are installed on the same vertical line.

[0022] 2) In the present invention, the displacement direction of the linear motor relative to the induction plate is the same as the displacement direction of the electromagnet relative to the steel rail, which can reduce the air gap of the linear motor, improve the traction efficiency of the linear motor, and reduce the energy consumption.

[0024] 4) In the present invention, the suspension frame adopts a rail-holding structure, which not only facilitates the installation and maintenance of the suspension frame, but also has good heat dissipation for the electromagnet.

[0025] 5) The frame of the present invention is of a rectangular structure with a hollow middle part, which can be used to install various vehicle-mounted devices.

[0026] 6) In the present invention, both the steel rail and the induction plate are installed below the first and second flanges of the track girder, which improves the running ability of the vehicle in snowy and icy weather. BRIEF DESCRIPTION OF THE DRAWINGS

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0039] As Figures 2 to 7 , an embodiment of the suspended maglev transportation system of the present invention includes an orbit 1, a suspension frame 2, an air spring 5, and a vehicle body 8. The orbit 1 is suspended in the air, the suspension frame 2 is suspended and installed on the orbit 1, and the vehicle body 8 is suspended and installed by the air spring 5, the vehicle body moving platform 3 and the swing rod 6.

[0040] The orbit 1 includes a beam body 11, a rail 12, and an induction plate 13. The beam body 11 is integrally box-shaped, with first flanges 111 provided on both sides of its top and second flanges 112 provided on both sides of its bottom. The rail 12 is installed below the first flange 111, and the induction plate 13 is installed below the second flange 112.

[0041] The suspension frame 2 includes an electromagnet 14, an upper support arm 15, a linear motor 16, a frame 17, and a lower support arm 18. The frame 17 is a rectangular structure formed by connecting two longitudinal beams 19 and two cross beams 20. The two linear motors 16 are respectively installed on the upper surfaces of the two longitudinal beams 19 of the frame and are oppositely installed with the induction plate 13 on the track 1. Four upper support arms 15 are respectively installed on the ends of the two cross beams 20 of the frame, and four lower support arms 18 are respectively installed on the lower surfaces of the ends of the two cross beams 20 of the frame. The two electromagnets 14 are respectively installed on the upper support arms 15 on both sides of the frame 17 and are located on the second flange 112 of the track beam body 11, and are oppositely arranged with the rail 12 installed under the first flange 111. When the electromagnet 14 is energized, the electromagnet 14 generates an electromagnetic suction force on the rail 12, and the displacement direction of the electromagnet 14 relative to the rail 12 is the same as the displacement direction of the linear motor 16 relative to the induction plate 13. When the electromagnet 14 is energized, the air gap between the linear motor 16 and the induction plate 13 is reduced, improving the traction efficiency of the linear motor 16 and reducing the energy consumption. The upper support arm 15 surrounds the track 1, forming a rail-holding structure between the suspension frame 2 and the track 1, which not only facilitates the installation and maintenance of the suspension frame 2 but also provides good heat dissipation for the electromagnet 14. To protect the electromagnet 14, skids and support wheels (not shown in the figure) are provided at the bottom of the electromagnet 14.

[0042] The four air springs 5 are respectively installed on the four lower support arms 18, and the tops of the air springs 5 are respectively installed with the vehicle body moving platform 3.

The swing rod 6 is vertically installed, with one end connected to the vehicle body moving platform 3 and the other end connected to the vehicle body 8. The vehicle body 8 can move laterally relative to the frame 17 through the swing rod 6. The rocker 4 is horizontally installed, with one end connected to the vehicle body moving platform 3 and the other end connected to the lower support arm 18. The installation of the rocker 4 enables the vehicle body moving platform 3 to only have a vertical displacement. A lateral stop 7 is also installed on the lower support arm 18 to limit the lateral rotation of the swing rod 6.

[0044] The vehicle body 8 is hung on the swing rod 6, and the vehicle body 8 is connected to the longitudinal beam 19 of the suspension frame 2 through two groups of Z-shaped three-section traction tie rods 9 to realize the traction of the suspension frame 2 on the vehicle body 8.
