Description

Technical Field

[0001] This utility model relates to the field of arch rib installation and construction technology, and in particular to an arch rib segment transportation device. Background Technology

[0002] In modern bridge construction, steel arch bridges, with their superior mechanical properties and material characteristics, have become the preferred choice for constructing long-span bridges and heavy-load-bearing structures. This type of bridge uses steel as the primary building material and cleverly utilizes the mechanical advantages of the arch structure. The arch design effectively transforms loads into compressive stress, thus providing strong load-bearing capacity. The high strength, good ductility, and excellent corrosion resistance of steel ensure the bridge's durability under various environmental conditions. During the design and construction process, modern steel arch bridges are typically divided into multiple arch rib segments for prefabrication in specialized steel structure processing plants. Although these arch rib segments are relatively small in size and easy to process, the weight and slender shape of each segment still pose significant challenges for transportation during on-site installation. Placing the arch rib segments horizontally during transportation reduces transportation risks; however, during installation, the segments must be lifted, rotated, and their orientation adjusted before installation. Placing the arch rib segments vertically during transportation makes it difficult to ensure their stability. Utility Model Content

[0030] Example. A segmental transport device for arch ribs, structural reference. Figures 1 to 4 An arch rib segment transport device is characterized by comprising two rows of parallel moving wheels 1, a loading platform 2 on the top surface of the moving wheels 1, the length of the loading platform 2 being greater than or equal to the length of the arch rib segment, limit frames 3 symmetrically arranged on both sides of the top surface of the loading platform 2, several support rods 4 oppositely arranged on the opposite sides of the limit frames 3, and a support frame 5 rotatably mounted on the top of the limit frames 3. Through the coordinated action of the moving wheels 1, loading platform 2, limit frames 3, support rods 4, and support frame 5, the device can effectively transport heavy arch rib segments 14 (weighing more than 10 tons), ensuring the stability of the transportation process and facilitating the hoisting operation of the arch rib segments 14.

[0031] Several stiffening plates 6 are provided along the centerline of the bottom surface of the loading platform 2. The stiffening plates 6 are trapezoidal in shape, perpendicular to the centerline of the bottom surface of the loading platform 2, and the longer side of the trapezoid connects to the bottom surface of the loading platform 2. By providing stiffening plates 6 along the centerline of the bottom surface of the loading platform 2, the load-bearing capacity of the loading platform 2 is improved, so as to prevent the loading platform 2 from undergoing plastic deformation or even failure when the arch rib segment 14 is placed on the loading platform 2.

[0032] The end of the support rod 4 connected to the limiting frame 3 is rotatably connected, and the support rod 4 is a telescopic structure. The telescopic structure of the support rod 4 includes a threaded rod 7 located in the middle of the support rod 4, with both ends of the threaded rod 7 threadedly connected to the support rod 4. By adopting the telescopic setting of the support rod 4, it extends to make close contact with the arch rib segment 14 during transportation, ensuring the stability of the arch rib segment 14.

[0033] The limiting frame 3 includes several uprights 8, which are connected by several horizontal braces 9 on the same side. Scissor braces 10 are installed between the horizontal braces 9. The uprights 8, horizontal braces 9, and scissor braces 10 are made of H-beams. By setting the uprights 8, horizontal braces 9, and scissor braces 10 to work together, the overall rigidity of the limiting frame 3 is improved, better supporting the arch rib segment 14.

[0034] The support frame 5 includes uprights 11, which are matched and corresponding to columns 8 and are rotatably connected to columns 8. The end of the uprights 11 away from the columns 8 is connected to a crossbar 12, which is round. By configuring the uprights 11 and crossbar 12 to work together and fit tightly with the arch rib segments 14, necessary support is provided for the arch rib segments 14 to prevent overturning during transportation. By making the crossbar 12 round, it is easy for the crossbar 12 to contact the arch rib segments 14. At the same time, for different arch rib segments 14, due to different installation positions, the size, length and weight of each arch rib segment 14 are not the same. If a fixed support structure is used, the stability of the arch rib segments 14 during transportation cannot be guaranteed. However, by using the method of rotating the crossbar 12 and the uprights 11 together, the support frame 5 can always contact the arch rib segments 14 of different sizes and lengths to form a stable support point.

[0035] An operating platform 13 is provided on the top of the opposite side of the limiting frame 3. The operating platform 13 facilitates the operation of transporting the arch rib segment 14 and allows the operator to easily flip the support frame 5 to contact the arch rib segment 14.

[0036] The upright 11 is formed by splicing two channel steels with opposite open faces. By splicing two channel steels with opposite open faces and connecting them by welding at the splice, the structural rigidity of the upright 11 is fully guaranteed.

[0037] The rotating connection is a hinge.

[0038] The working principle and usage of this utility model: The main application scenario of this device is in the construction process of steel truss arch bridges and steel-concrete composite arch bridges. When installing the arch ribs of the arch bridge, the arch rib segment 14 is hoisted onto this device at the arch rib processing site and then transported to the construction site. During hoisting, the arch rib segment 14 is first vertically hoisted between the two limiting frames 3, the support rod 4 is flipped so that the telescopic end of the support rod 4 faces the arch rib segment 14, and the threaded rod 7 is rotated so that the support rod 4 and the arch rib segment 14 are tightly fitted. Then the support frame 5 is flipped so that the crossbar 12 and the arch rib segment 14 are tightly fitted. To fully reinforce, steel cables are tied at the contact points between the crossbar 12 and the arch rib segment 14 to ensure the stability of the arch rib segment 14 during operation.

[0039] Obviously, the above description is only a part of the embodiments of this utility model, and not all of them. The above embodiments are not intended to limit this utility model, and various modifications and variations can be made to this utility model by those skilled in the art. Any combination, modification, equivalent substitution, improvement, and all other embodiments that can be made by those skilled in the art within the spirit and principles of this utility model should be within the protection scope of this utility model.
