Description

Arch rib section conveyer Technical Field The utility model relates to the technical field of arch rib installation and construction, in particular to an arch rib section conveying device. Background In modern bridge construction, the steel structure arch bridge is the first choice for constructing a large-span bridge and bearing a heavy load structure due to the excellent mechanical property and material property. The bridge adopts steel as a main building material, and ingeniously utilizes the mechanical advantage of an arch structure. The arch design can effectively convert load into compressive stress, and then provides strong bearing capacity. The high strength, good ductility and excellent corrosion resistance of the steel ensure the durability of the bridge under various environmental conditions. In the design and construction process, modern steel construction arch bridges typically split the arch bridge into multiple rib segments for prefabrication within a specialized steel construction process plant. While these rib segments have been relatively small in size for ease of handling, the weight of each rib segment and its elongated shape still place high demands on transportation when installed in the field. In the transportation process, if the arch rib sections are horizontally placed, the transportation risk can be reduced, however, in the installation stage, the arch rib sections must be lifted and turned over first, and the installation can be performed after the posture of the arch rib sections is adjusted. If the rib segments are placed vertically during transport, it is difficult to ensure their stability. Disclosure of utility model The utility model provides a rib segment conveying device, which aims to at least solve the technical problems in the prior art mentioned in the background art. The utility model provides the following technical scheme to achieve the above purpose: The arch rib section conveying device is characterized by comprising two rows of movable wheels which are arranged in parallel, wherein the top surfaces of the movable wheels are provided with loading platforms, the lengths of the loading platforms are greater than or equal to those of the arch rib sections, limiting frames are symmetrically arranged on two sides of the top surfaces of the loading platforms, a plurality of supporting rods are oppositely arranged on opposite sides of the limiting frames, and supporting frames are rotatably arranged at the top ends of the limiting frames. Furthermore, a plurality of stiffening plates are arranged on the central line of the bottom surface of the loading platform, the stiffening plates are arranged in a trapezoid shape, the trapezoid is perpendicular to the central line of the bottom surface of the loading platform, and one longer side of the trapezoid is connected with the bottom surface of the loading platform. Furthermore, one end of the stay bar connected with the limiting frame is rotationally connected, and the stay bar is of a telescopic structure. Still further, the extending structure of vaulting pole includes the threaded rod that sets up at the vaulting pole middle part, and the both ends and the vaulting pole threaded connection of threaded rod. Still further, the spacing includes a plurality of stands, connects through a plurality of horizontal braces between the homonymy stand, is provided with the stull between the horizontal brace. Still further, the support frame includes the pole setting, and the pole setting matches with the stand and corresponds the setting, and the pole setting rotates with the stand to be connected, and the pole setting is kept away from the one end of stand and is connected the horizontal pole jointly, and the horizontal pole is the round bar setting. Further, the top of the opposite sides of the limiting frame are oppositely provided with an operation platform. Furthermore, the vertical rods are formed by splicing channel steel with two opposite opening surfaces. Furthermore, the upright post, the horizontal support and the scissor support are made of H-shaped steel. Further, the rotational connection is hinged. Advantageous effects Compared with the prior art, the utility model has the following beneficial effects: 1. According to the utility model, through the synergistic effect of the movable wheels, the loading platform, the limiting frame, the supporting rods and the supporting frames, the effective transportation of the counterweight arch rib sections can be realized, the stability of the transportation process is ensured, and the lifting operation of the arch rib sections is facilitated. 2.
