Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model.

Therefore, the following detailed description of the embodiments of the present utility model provided in the accompanying drawings is not intended to limit the scope of the present utility model claimed, but merely represents selected embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0029] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of the present utility model, the terms "first", "second", etc. are only used for descriptive distinction and cannot be understood as indicating or implying relative importance.

[0030] There are currently two main forms of suspended tracks. One is a steel beam + rubber wheel, that is, the car body moves directly on the steel beam through rubber wheels; the other is a concrete beam + concave-shaped suspension arm method, that is, a concave-shaped suspension arm is provided above the car body, and the suspension arm is stuck in the concrete beam so that the car body is suspended below the concrete beam for movement.

[0031] However, neither rubber wheels nor suspension arms can bear a large weight, and due to considerations of the load-bearing capacity and safety of the beam body, the design speeds of these two types of tracks are relatively low. Currently, they are mainly used for tourist line passenger transport and cannot meet the needs of heavy-haul freight transport.

[0032] To solve the existing technical problems, as Figure 1 and Figure 2 shown, the present application provides a suspended steel beam track, including:

[0033] Two steel beams 100, the two steel beams 100 are parallel to each other, and the steel beams 100 are erected in the air;

[0034] Two steel rails 200, and the two steel rails 200 are respectively fixed to the steel beam 100 through fasteners 300;

[0035] Mounting frame 400, both ends of the mounting frame 400 are arranged on the steel beam 100, and the middle part of the mounting frame 400 straddles the two steel rails 200 and is higher than the height of the vehicle body 700 traveling on the steel rails 200;

[0036] Contact rail return device, the contact rail return device is arranged on a plurality of the mounting frames 400 and is located above the vehicle body 700.

[0037] The present application proposes a suspended track system combined with a steel beam 100 and steel rails 200. The steel rails 200 are arranged on the steel beam 100, and the rubber wheels of the freight vehicle body 700 are changed to steel wheels matching the steel rails 200, so as to achieve high load capacity of the freight track and improve the transportation speed at the same time. This suspended steel beam track is applicable to port container transfer or freight transportation in high-altitude areas.

[0038] As Figure 2 shown, the steel beam 100 adopts a T-shaped steel beam, the wheels are in contact with the steel rails 200, and the vehicle body 700 is suspended in the gap between the steel beams 100. The contact rail return device is arranged directly above the vehicle body 700.

[0039] As an alternative embodiment, as Figure 1 shown, the fasteners 300 are symmetrically arranged on both sides of the steel rails 200; bolt holes are formed in the steel beam 100, and the fasteners 300 include bolts 301, nuts 302, spring washers 303, buckle plates 304 and stoppers 305;

[0040] One end of the buckle plate 304 presses on the bottom of the steel rail 200, the bolt 301 passes through the bolt hole from below the steel beam 100, and sequentially connects and fixes the buckle plate 304, the spring washer 303 and the nut 302; the stopper 305 is arranged between the buckle plate 304 and the steel beam 100.

[0041] The middle parts of the upper and lower surfaces of the buckle plate 304 are both recessed inward. The spring washer 303 is arranged at the recessed position on the upper surface, and the nut 302 presses on the spring washer 303; the protruding position on the lower surface contacts the stopper 305. One side of the buckle plate 304 close to the steel rail 200 extends outward, and the lower surface of the extended part is consistent with the profile of the bottom of the rail, pressing the bottom of the rail.

[0042] As an alternative embodiment, the fasteners 300 are symmetrically arranged on both sides of the rail 200; bolt holes are provided on the steel beam 100, and the fasteners 300 include bolts 301, nuts 302, spring washers 303, elastic bars and elastic bar supports; that is, the difference between this embodiment and the above-mentioned fasteners 300 is only that the buckle plate 304 is replaced by an elastic bar, and the stop block 305 is replaced by an elastic bar support.

[0043] One end of the elastic bar is pressed on the bottom of the rail 200, and the bolt 301 passes through the bolt hole from below the steel beam 100, and sequentially connects and fixes the elastic bar support, the elastic bar, the spring washer 303 and the nut 302. If the structure of the fastener 300 of this embodiment is adopted, the elastic bar support needs to be welded and fixed to the steel beam 100.

The support columns 900 are similar to bridge piers, and the heights of the plurality of support columns 900 may be different, and specific design needs to be carried out according to the local terrain conditions.

[0045] Refer to Figure 2 , as an alternative embodiment, the contact rail return device includes a power receiving rail 500 and a return rail 600. The main function of the contact rail return device is to provide power for the vehicle body 700 and ensure that the current can return to the power source. The vehicle body 700 receives power by friction between the pantograph and the power receiving rail 500, and the return rail 600 ensures that the current can return to the power source, thereby ensuring the normal operation of the vehicle body 700.

[0046] As an alternative embodiment, a plurality of mounting frames 400 are arranged along the steel beam 100, and the two legs of the mounting frame 400 are respectively fixed on the two steel beams 100, so that the mounting frame 400 straddles the rail 200; the power receiving rail 500 and the return rail 600 are arranged in the middle of the mounting frame 400.

[0047] As an alternative embodiment, the height of the mounting frame 400 is 1550 - 1650 mm, preferably 1600 mm, and preferably the top of the mounting frame 400 is more than 600 mm away from the top surface of the vehicle body 700. The space between the mounting frame 400 and the top surface of the vehicle body 700 is used to install the contact rail return device. The power receiving rail 500 is 220 - 260 mm higher than the top of the vehicle body 700, and the return rail 600 is 50 - 80 mm higher than the top of the vehicle body 700.

[0048] To avoid rigid contact between the rail 200 and the T-shaped steel beam 100, as an alternative embodiment, an elastic cushion plate 800 is provided between the rail 200 and the steel beam 100, which can absorb the vibration of the rail 200 and improve the stability and service life of the track.

[0049] To reduce the load on the steel beam 100, a lightweight design is preferably adopted. As an alternative embodiment, the rail 200 is a 43 kg / m rail with a rail height of 140 mm, a bottom width of 114 mm, a head width of 70 mm, and a web thickness of 14.5 mm.

[0050] As an alternative embodiment, the distance between the two rails 200 is 950 - 1100 mm, preferably 1000 mm. The thickness of the elastic cushion plate 800 is preferably 10 mm, which is the same as the thickness of the stop block 305.

[0051] The above is only the specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
