[0066] As Figures 1 to 13 As shown, in one embodiment, the present invention provides a bridge erection module, and the bridge erection module includes a bridge main body 1 and a movable part 2;

[0067] One end of the bridge main body 1 has a fixed slope end 11, the other end of the bridge main body 1 has a movable end 12, and the fixed slope end 11 has a first slope 15 gradually extending between the first end face 13 on one side of the bridge main body 1 and the second end face 14 on the other side.

[0068] The movable part 2 is hinged on the movable end 12. When the movable part 1 rotates along the hinge to the first position, the third end face 21 of the movable part 2 is flush with the first end face 12, and the fourth end face 23 of the movable part 2 is used as the second slope 22. When the movable part 2 rotates along the hinge to the second position, the fourth end face 23 of the movable part 2 is flush with the second end face 14 and is fixed by a fixing mechanism 24.

[0069] In this embodiment, a specific structure of a bridge erection module is provided. The bridge main body 1 is trapezoidal or parallelogram-shaped when viewed from the side. During use, the first end face 13 serves as the upper surface, and the second end face 14 serves as the lower surface. Since the length of the bridge may have different requirements, perhaps a single bridge erection module can achieve the purpose, or multiple bridge erection modules can be assembled to achieve it. This can be applied to scenarios with different widths of riverbanks, improving the flexibility of use. Of course, the bridge main body 1 should also have an appropriate width and thickness, which is related to the needs of vehicles or pedestrians crossing the bridge, and conventional design can be used. The fixed slope end 11 is simply a slope, that is, the first slope 15, while the other end is provided with a movable part 2. It should be noted that preferably, the side of the movable part 2 is triangular and has a certain thickness, preferably the same as the thickness of the bridge main body 1. It has two hinge positions. After being hinged through the hinge points, one side of the movable part 2 is hinged to the bridge main body 1, and the other side, that is, the third end face 21. When in the first position, the third end face 21 is flush with the first end face 12, and the whole forms a trapezoid. At this time, the fourth end face 23, the last side of the triangle, will be connected to the second end face 14 to form the second slope 22. This is the method of using a single bridge erection module alone. However, when the distance between the two banks exceeds the length of the bridge erection module, it is necessary to build it in an overlapping manner to adapt to a longer distance between the two banks. When the movable part 2 moves to the second position, the fourth end face 23 is flush with the second end face 14. At this time, the bridge erection module is in a parallelogram shape, and the other bridge erection modules are overlapped with each other in the first position to form a trapezoid as a whole to meet the situation of a long distance between the two banks, which helps to solve the technical problem of insufficient flexibility of the existing rapid bridge erection equipment for different application scenarios.

[0070] In one embodiment, one end of the first hinge link 16 is connected to the other end of the bridge main body 1, and one end of the second hinge link 17 is connected to the movable part 2. The first hinge link 16 and the second hinge link 17 are hinged.

[0071] In this embodiment, a specific structure of the hinge is provided. In order to prevent possible interference between the movable part 2 and the bridge main body 1, the ends of the first hinge link 16 and the second hinge link 17 are hinged and connected, and are respectively connected to the joint cross-section of the movable part 2 and the bridge main body 1.

[0072] In one embodiment, the fixing mechanism 24 includes a fixing rod 241;

[0073] One end of the fixing rod 241 is connected to the bridge main body 1, and the other end of the fixing rod 241 is fixed to the movable part 2 by bolts.

[0074] In this embodiment, a specific structure of the fixing mechanism 24 is provided.

[0075] In one embodiment, the angle between the first slope surface 15 and the second end surface 14 is less than 13 degrees.

[0076] In this embodiment, a preferred angle of the first slope surface 15 is provided, and the preferred angle of the second slope surface 22 can also be 13 degrees.

[0077] In one embodiment, the bridge main body 1 includes two lower main girders 18, a plurality of cross beams 19, two upper main girders 110, and a bridge deck 111;

[0080] The two upper main girders 110 are respectively arranged on the cross beam 19 and are arranged along the length direction of the lower main girder 18;

[0081] The bridge deck 111 is arranged between the two upper main girders 110 to form the first end surface 13.

[0082] In this embodiment, a specific structure of the bridge main body 1 is provided. In terms of the cross section, the lower main girder 18 is an I-beam, and the lower main girder 18 and the cross beam 19 are supported and fixed by two longitudinal beams on the left and right. The upper main girders 110 are located on both upper sides, and the upper main girder 10 is a T-beam. In addition, a rib plate is arranged between the longitudinal beam support and the cross beam 19.

[0083] The bridge erection module is assembled by two center-symmetric rut-type structures. The two sides of the structure are the main load-bearing lower main girders 18, and the middle is the bridge deck 111 that supports the wheels. The entire structure can effectively reduce the weight of the bridge span.

[0084] In the bridge erection module, the upper main girder 110, the lower main girder 18, the bridge deck 111, and the cross beam 19 of the bridge span are all aluminum alloy extrusion profiles, and the profile cross section is as large as possible, greatly reducing the number and length of welds in the entire structure, and avoiding welding of aluminum alloy materials at the main stress-bearing parts, reducing the influence of welding on the yield strength of aluminum alloy materials, enabling the strength of aluminum alloy materials to exert its maximum efficiency, and achieving the purpose of structural lightweight.

[0085] In one embodiment, the present invention also provides a combined bridge built by the bridge erection module. The combined bridge includes at least two of the bridge erection modules;

[0086] At least two of the bridge erection modules include a first bridge erection module and a second bridge erection module;

[0087] The movable part 2 of the first bridge erection module is in the first position;

[0088] The movable part 2 of the second bridge erection module is in the second position, and the first slope surface of the first bridge erection module and the second slope surface of the second bridge erection module are lapped to form the first end surface of the first bridge erection module and the second end surface of the second bridge erection module being flush, and the first end surface of the second bridge module and the first end surface of the first bridge erection module are flush.

[0089] In this embodiment, a connection method between the first bridge erection module and the second bridge erection module forms a combined bridge.

[0090] In one embodiment, a hook 131 is arranged on the first slope surface 13 of the first bridge erection module, and a pin shaft 221 is arranged on the second slope surface 22 of the second bridge erection module. After the first bridge erection module and the second bridge erection module are lapped, the hook 131 is buckled on the pin shaft 221.

[0091] In this embodiment, the specific structures of the hook 131 and the pin shaft 221 are provided to further make the lap joint between the first bridge erection module and the second bridge erection module stable.

[0092] In one embodiment, the present invention also provides a combined bridge built by bridge erection modules, and the combined bridge includes at least two of the bridge erection modules;

[0093] At least two of the bridge erection modules include a first bridge erection module and a second bridge erection module. The first bridge erection module and the second bridge erection module are arranged side by side at the same direction with an interval, and both ends of the connection device are fixedly connected between the first bridge erection module and the second bridge erection module;

[0094] A cover plate 3 is arranged between the tops of the first bridge erection module and the second bridge erection module to jointly form an upper bridge deck.

[0095] In this embodiment, the specific structure of arranging modules side by side to form a combined bridge is provided. The connection device can be connected at different positions, for example, at the left and right ends of the cross beam 19, or at the left and right sides below the bridge deck 11.

[0096] In one embodiment, railings 3 are respectively arranged on both sides of the first bridge erection module and the second bridge erection module.

[0098] In one embodiment, engine modules 4 are respectively arranged on the first bridge erection module and the outside of the first bridge erection module.

[0099] In this embodiment, a specific structure for setting the engine module 4 is provided. The first bridge erection module and the first bridge erection module can be driven by the engine module 4 to travel in water. Connection ears for module connection are arranged on both sides of the bridge erection module. The bridging vehicle places the modular bridge in the shallow water area, installs the engine module to travel, and acts as a ferry. At the same time, multiple modular bridges installed with engines can be connected together to form a floating bridge for use.

[0100] Advantages:

[0101] 1. The bridge erection module can be used alone or in series, greatly improving the flexibility in use.

[0102] 2. A single bridge erection modular bridge has independent functions and structures, can be manufactured and used separately.

[0103] A single module can be used alone as a bridge span. When encountering small gully obstacles, two bridge spans can be erected to ensure passage. When used alone, the up-and-down bridge slopes at both ends are not greater than 13°, which can ensure that vehicle passage is not affected.

[0104] 3. A single bridge erection modular bridge itself is at least rotationally symmetric by 180°. During the process of combining into a long bridge, there is no need to adjust the direction, achieving the purpose of rapid combination and connection.

[0105] 4. Fast connectivity. A single bridge erection modular bridge has combinability and connection interfaces. Multiple modular bridges can be organically combined to form long bridges of different lengths. Moreover, the modular bridge is easy to assemble, disassemble and replace in new products, with universality, interchangeability and compatibility.

[0106] A single bridge section module consists of a pair of main bridge sections and a pair of flipping bridge sections. The structures of the two bridge section modules are exactly the same, which can ensure universality and interchangeability. When connecting the bridge section modules, the movable end bridge sections of the two bridge section modules can swing upward, and then be inserted and assembled with the corresponding fixed slope ends 11. The connection part adopts the method of lower pin shafts 221 and hooks 151 to ensure the stability and reliability of the bridge span connection part.

[0107] The above embodiments are only exemplary embodiments of the present invention and are not used to limit the present invention. The protection scope of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present invention, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present invention.
