Description

Technical Field

[0001] This invention relates to the field of Bailey bridges, and more specifically, to an adjustable connection device for Bailey bridges. Background Technology

[0002] Bailey bridges are among the most widely used and popular types of bridges in the world. They are characterized by their simple structure, convenient transportation, rapid erection, and easy disassembly. They also possess advantages such as high load-bearing capacity, strong structural rigidity, and long fatigue life. They can be assembled into various types of temporary bridges, emergency bridges, and permanent bridges for different purposes according to actual needs, and are characterized by fewer components, light weight, and low cost.

[0003] Existing Bailey truss assemblies use a "window" connection device, but the window is a universal component, only available in 450mm and 900mm sizes. When using window connections, the distance between Bailey trusses can only be adjusted by using different window sizes because the window is not adjustable. The fixed connection spacing results in poor adaptability. Furthermore, some Bailey trusses use a "tie rod" connection device, where the tie rod passes laterally through two Bailey trusses and is fixed by bolts. Without diagonal bracing to form a stable triangular structure, stability is poor. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention provides an adjustable connection device for a Bailey bridge, which is equipped with an adjustable structure to adjust the distance of the Bailey bridge. At the same time, the device and the Bailey bridge are connected to form a triangular support structure, which improves the overall stability of the device.

[0005] To achieve this objective, the present invention adopts the following technical solution: This invention provides an adjustable connection device for a Bailey bridge, including a Bailey bridge, a tie rod, a U-shaped flange, and a circular flange. Two Bailey bridges are arranged in parallel. The tie rod is installed inside the Bailey bridge. The two ends of the U-shaped flange are respectively connected to the two ends of the tie rod. The U-shaped flange has a plurality of first bolt holes, and the circular flange has a plurality of second bolt holes. The two U-shaped flanges are respectively connected to the circular flange.

[0006] In a preferred embodiment of the present invention, the end of the U-shaped flange and the end of the tie rod are connected by bolts.

[0007] In a preferred embodiment of the present invention, two circular flanges are provided, which are arranged in parallel and are respectively connected to the front and rear ends of the U-shaped flange.

[0008] In a preferred embodiment of the present invention, the second bolt holes on the circular flange are evenly distributed.

[0009] In a preferred embodiment of the present invention, the circular flange and the U-shaped flange are fixed together by inserting bolts between the first bolt hole and the second bolt hole.

[0010] In a preferred embodiment of the present invention, the first bolt holes on the U-shaped flange are symmetrically arranged on both arms with the central axis of the U-shaped flange as the center.

[0011] The beneficial effects of this invention are as follows: This invention provides an adjustable connection device for Bailey bridge assemblies. A U-shaped flange is bolted to a tie rod to form a triangular tie rod structure. The triangular tie rod is connected to the Bailey bridge panels. A circular flange is positioned in the middle, connecting two triangular tie rods into one unit. Bolt holes are provided on both the triangular tie rods and the flange, allowing adjustment of the connection position to adjust the length of the device and further adjust the spacing of the Bailey bridge assemblies. This connection device is designed as an adjustable structure to adapt to different Bailey bridge assembly connection spacings. Furthermore, the triangular structure of this device provides high stability. It solves the problems of non-adjustable connection spacing and poor stability of tie rods in traditional window frame installations. This connection device is highly adaptable, stable, and easy to assemble. Its length can be adjusted according to the spacing of the Bailey bridge assemblies, making it highly adaptable. The triangular structure design ensures high stability, and the bolted connection facilitates easy assembly. Attached Figure Description

[0014] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0015] like Figures 1-2 As shown, an adjustable connection device for a Bailey bridge frame is provided in the embodiment, including a Bailey bridge frame, a tie rod, a U-shaped flange, and a circular flange. Two Bailey bridge frames are arranged in parallel. The tie rod is installed inside the Bailey bridge frame. The two ends of the U-shaped flange are respectively connected to the two ends of the tie rod. The U-shaped flange has multiple first bolt holes, and the circular flange has multiple second bolt holes. The two U-shaped flanges are respectively connected to the circular flange.

[0016] Furthermore, the ends of the U-shaped flange and the tie rod are connected by bolts.

[0017] Furthermore, two circular flanges are provided, arranged in parallel, and connected to the front and rear ends of the U-shaped flange respectively.

[0018] Furthermore, the second bolt holes on the circular flange are evenly spaced.

[0019] Furthermore, the circular flange and the U-shaped flange are fixed together by inserting bolts between the first bolt hole and the second bolt hole.

[0020] Furthermore, the first bolt holes on the U-shaped flange are symmetrically arranged on both arms with the central axis of the U-shaped flange as the center.

[0021] When using this device, the first step is to assemble it. Connect both ends of the U-shaped flange to the tie rods of the Bailey bridge. The ends of the U-shaped flange are fixed to the tie rods with bolts. The circular flange connects to the U-shaped flanges on both sides. Multiple second bolt holes on the circular flange correspond to multiple first bolt holes on the U-shaped flange. The bolt positions can be flexibly selected according to actual installation needs to adjust the length of the Bailey bridge. This device uses the connection between the U-shaped and circular flanges to adjust the width of the Bailey bridge, thus achieving length adjustment. Furthermore, the U-shaped flange, after being connected to the tie rod, forms a triangular structure, providing strong stability. The entire device is connected with bolts, making assembly quick and convenient.
