Abstract

The invention relates to a lifting appliance for lifting segment steel beams. The lifting appliance for the segment steel beams comprises a cross beam, upper lifting lugs, lower lifting lugs, pulleys, soft lifting belts and baffles, wherein the pulleys are connected to the lower lifting lugs, the soft lifting belts are wound around the pulleys and are used for lifting the segment steel beams, and the baffles are arranged on the pulleys and are used for preventing the soft lifting belts from sliding out of the pulleys; and end seats are arranged at the two ends of the cross beam, the upper lifting lugs are arranged over the end seats, and the lower lifting lugs are arranged under the end seats. The lifting appliance for lifting the segment steel beams is wide in application range, low in site requirement, high in treatment efficiency, simple in operation and economical, the construction process is safe and controllable, and the problem that the lifting by a gantry crane is unbalanced can be solved.

Description

technical field [0001] The invention belongs to the technical field of bridge construction hoisting, and in particular relates to a hoisting tool for hoisting segmental steel girders. Background technique [0002] The Pingtan Strait Road-Railway Bridge is the first cross-strait road-railway bridge in my country. The Strait Bridge is different from the Bay Bridge built in the past. Its construction faces harsh conditions such as strong winds, high waves, surges, strong typhoons, and complex geology. The construction of the bridge brought great challenges and high risks. This bridge is the first attempt in the field of cross-strait bridges in China. Whether it is the harshness of the environment, or the technical challenges and construction risks it faces, it is far superior to other cross-sea bridges that have been built or are under construction in China. The Pingtan Strait Highway-Railway Bridge is the first time in the world to build a Strait Bridge in a complex wind and...
