Description

Arch rib section turning device Technical Field The utility model relates to the technical field of arch rib segment overturning, in particular to an arch rib segment overturning device. Background In the process of constructing a modern steel structure arch bridge, a strategy of thinning an arch bridge structure into a plurality of arch rib sections is generally adopted so as to facilitate efficient prefabrication in a professional steel structure processing plant. Common steel arch bridge forms include steel truss arches, steel box-truss composite arches, steel box arches, profiled section steel arches, and the like. Although the arch rib sections are relatively optimized in size and convenient to process and manufacture, when in assembly operation on site, each arch rib section still cannot be neglected in size and weight, can be tens of meters long and high in size, and can be about one hundred fifty tons in weight. Therefore, the arch rib is assembled in a horizontal mode during assembling, and when the arch rib is required to be installed after the assembling, the arch rib sections are turned vertically and conveyed to an arch bridge for installation. However, in the process of turning over vertically, if the arch rib section is used as a turning over shaft for turning over, the working difficulty is high, and the local structure of the arch rib section can be damaged, so that the structural safety of the whole bridge is affected. Therefore, there is a need to develop a device for assisting in turning over of rib segments, ensuring the structural integrity of the rib segments during turning over, to ensure engineering quality and safety. Disclosure of Invention The utility model provides an arch rib section overturning device, and aims to provide a device which is convenient for overturning an arch rib section and ensures the structural integrity of the arch rib section in the overturning process. The utility model provides the following technical scheme to achieve the above purpose: The arch rib section overturning device comprises a seat, wherein a side plate is arranged on one side of the top surface of the seat, a clamping seat is arranged in the center of the top surface of the seat, and the bottom of one side of the side plate of the seat is arranged in an arc shape. Further, the curved line of the table arc comprises a quadratic parabola, a spiral line and a logarithmic curve; Further, the seat comprises a plurality of longitudinal plates which are arranged in parallel, and the longitudinal plates are connected through a plurality of transverse plates; further, the arc-shaped part of the seat table is provided with a transverse stiffening structure; further, the size of the clamping seat is matched with the width setting of the arch rib section; Further, the transverse stiffening structure comprises H-shaped steel, angle steel and steel pipes; furthermore, the seat, the side plates and the clamping seat are made of Q235 steel or Q345 steel; Advantageous effects Compared with the prior art, the utility model has the following beneficial effects: 1. The utility model provides a device convenient for overturning an arch rib section, which is arranged at the bottom of the arch rib section when in use, and the other end of the arch rib section is lifted by a lifting device, so that the whole arch rib section takes the device as a rotating shaft to realize the overturning of the arch rib section. 2. The utility model is convenient to turn by arranging the seat table in an arc shape, and realizes the stability of the turning process by adopting the curve forms of a secondary parabola, a spiral line and a logarithmic curve. 3.
