Problems solved by technology
[0002] At present, the shell structure of the decoration part of the steel bridge adopts the conventional high-altitude bulk assembly scheme, which requires the erection of a large number of high-altitude scaffolding. Not only the high-altitude assembly and welding workload is huge, but also there are large quality and safety risks, and the technical and economic indicators of the scheme are poor.

Embodiment Construction
[0034] The present invention will be further described below in conjunction with accompanying drawing.
[0035] Such as figure 1 As shown, an overall lifting device for special-shaped thin-walled shell structures includes lifting frames 10 respectively arranged around the holes of the decorative structure on the arch ribs 9, and the lifting frames are cantilevered out relative to the inner side of the arch ribs as a whole. A hydraulic lifter 2 is provided on the lifting frame 10, and the hydraulic lifter 2 is fixedly arranged on the lifting frame 10 through the guide frame 1. The lower hanger 5 of the hydraulic lifter 2 is used to correspond to the steel structure shell The steel structure shell 8 is a special-shaped thin-walled shell structure, and the lifting lug 7 is set on the steel structure shell 8, and the lifting lug 7 is connected with the lower lifting tool 4 through the pin shaft 4, forming a Anchorage point6.

The invention discloses overall lifting equipment and method for a special-shaped thin-wall shell structure. The overall lifting equipment comprises lifting frames which are arranged on an arch rib and located on the periphery of a decorative structure hole, the lifting frames integrally stretch out in a cantilever mode relative to the inner side direction of the arch rib, and hydraulic lifters are fixedly arranged on the lifting frames through guide frames; a hydraulic lifter is arranged on the lifting frame, a lower lifting appliance of the hydraulic lifter is used for being connected with a lifting point on a corresponding steel structure shell, and the steel structure shell is of a special-shaped thin-wall shell structure. After a steel structure is assembled into a whole on the ground, a lifting frame is arranged on an installed arch rib structure, corresponding hydraulic lifters and related lifting equipment are arranged on the lifting frame, after the steel structure decoration ground is assembled, lifting work is carried out, and according to a hydraulic lifter cluster, through the synchronous repeated telescopic cylinder process, the steel structure decoration is gradually lifted to the designed position, safety and reliability are achieved, and the construction efficiency is high.
Description
technical field [0001] The invention relates to the technical field of bridge engineering construction, in particular to an overall lifting device and method for special-shaped thin-walled shell structures. Background technique [0002] At present, the shell structure of the decoration part of the steel bridge adopts the conventional high-altitude bulk solution, which requires a large number of high-altitude scaffolding. Not only the high-altitude assembly and welding workload is huge, but also there are large quality and safety risks, and the technical and economic indicators of the scheme are poor. . Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a safe, reliable, and improved construction efficiency equipment and method for overall lifting of special-shaped thin-walled shell structures in view of the shortcomings of the above-mentioned prior art. [0004] The technical solution adopted in the present inventi...
