Abstract

This utility model belongs to the field of bridge engineering technology, and particularly relates to a hydraulic outrigger device for a crane bridge erecting machine. Addressing the problems of cumbersome disassembly procedures, low construction efficiency, limited height adjustment, and difficulty in adapting to changes in bridge slope in existing bridge erecting machines, the following solution is proposed: a hydraulic cylinder is connected to the top of the main beam, and a bearing platform is connected to the bottom of the main beam. The output shaft of the hydraulic cylinder passes through the bearing platform and is connected to a lifting frame below the bearing platform. The same set of telescopic pipes are sleeved on the bearing platform and the lifting frame. Several pin holes are evenly arranged on the telescopic pipes, and pins are inserted into the pin holes. The hydraulic outrigger of this crane bridge erecting machine has high height adjustment efficiency, simple disassembly, and high safety. It can flexibly adjust the outrigger length according to different bridge and pier height requirements, adapting to the height adjustment needs of different piers on the same bridge. Furthermore, it is simple to install and disassemble in bridge construction on complex terrain.
