Description

Can realize revolving tower system of arch rib corotation and erectting Technical Field The application relates to the technical field of bridge construction, in particular to a rotary tower system capable of realizing horizontal rotation and vertical rotation of an arch rib. Background In the technical field of bridges, arch ribs are core stress members of an arch-shaped bearing structure, the appearance of the arch ribs is arc-shaped, and the arch ribs are connected with a foundation through arch legs at two ends to jointly form a bearing framework of the arch-shaped structure. At present, the common practice of arch rib installation is to adopt a horizontal rotation and vertical rotation separated installation device and a construction method around an arch springing. The horizontal rotation installation is to use the arch rib segments after the prefabrication is completed on the ground or a temporary support to be assembled and formed, and then to drive the arch rib to rotate horizontally around a vertical shaft by using the arch foot as a rotation center and by using a horizontal rotation driving device such as a turntable and the like until the arch rib rotates to a designed installation position, and the vertical rotation installation is also to use the arch foot as a rotation center, and drive the arch rib to rotate vertically around the horizontal shaft by using a rotating tower as a support and using a traction device to lift and hang the arch rib from a horizontal or inclined state to rotate to a designed installation angle. In the installation mode of the horizontal rotation and vertical rotation separation, two sets of different devices respectively implement the horizontal rotation and the vertical rotation. Because the pull point distance between the rotating tower and the front end of the arch rib is far, a large weight balance weight is arranged at the rear end of the arch springing to realize the stress balance in the arch rib rotating process. Because the balance weight is arranged at the bottom of the arch springing, the permanent structure is influenced, the design stage of the construction drawing is considered, otherwise, the design is required to be changed in the later stage, the construction period is delayed, the construction cost is further improved, and the safety of the engineering structure is even influenced. In summary, the existing arch rib flat and vertical rotation separated installation equipment has the defects of adverse effect on a permanent structure, high design and construction cost, easy delay of construction period and the like, so that the development of a set of arch rib installation equipment which can give consideration to the flat rotation and vertical rotation functions, does not need to arrange a balance weight at the rear end of an arch rib and can eliminate the influence on the permanent structure becomes the technical problem to be solved urgently in the current field.
