Box girder transfer platform and girder transferring and girder loading working procedures thereof

Abstract

The invention relates to a box girder transfer platform and girder transferring and girder loading working procedures thereof. The platform comprises a girder carrying trolley, a telescopic boom, a girder assembly, a door-shaped frame, a driving system, a hydraulic system and an electrical system, wherein the girder carrying trolley is arranged on the telescopic boom; the telescopic boom is supported by the door-shaped frame connected with pre-embedded foundation and the girder assembly arranged on the door-shaped frame; a driving device of the driving system is arranged at the rear end of the telescopic boom; guiding wheels of the driving system are arranged on front and rear end faces of the telescopic boom; a pump station of the hydraulic system is positioned on a girder of the door-shaped frame; a main cabinet of the electrical system is arranged on the girder of the door-shaped frame; the transfer platform can be used for transferring box girders, can transfer the box girders to one side of a bridge floor after the girders are taken from the girder carrying trolley; and after a bridge girder erection machine integrating transfer and erection operates to the side of the transfer platform, the girders are fed for the bridge girder erection machine integrating transfer and erection from the lateral side, so that parallel construction of the girder transfer and bridging is realized, and the girder erecting speed of the bridge girder erection machine integrating transfer and erection is improved greatly.

Description

technical field [0001] The invention relates to a box girder transfer platform and its beam moving and beam loading procedures. Background technique [0002] With the further strengthening and development of my country's infrastructure, the construction of various infrastructures is entering a rapid and steady development stage. The "Eleventh Five-Year Plan" of railways shows that China's railways have entered a stage of leapfrog development, especially since the economic crisis. my country has increased investment in infrastructure such as railways and highways, and railway construction has reached an unprecedented peak. As my country's railway construction enters a stage of continuous and rapid development, a key problem to be solved in the aspect of railway construction is how to carry out railway construction with low construction cost and high construction efficiency to meet the growing demand. So as to keep up with the pace of economic development. [0003] At present,...

AI Technical Summary

Problems solved by technology

Therefore, it is usually necessary to set up a special rotating platform on the outside of the bridge deck of the prefabricated beam yard on the construction site, through which the beam loading operation is performed, but the existing beam loading process is complicated and cannot be adapted to the loading and unloading of beams of different specifications
