Using method of deck crane for hoisting corrugated steel web segmental beam

Abstract

The invention provides a using method of a deck crane for hoisting corrugated steel web segmental girders, which adopts a main truss, a front fulcrum structure, a walking system, two lifting systems, two lifting appliances and a plurality of telescopic support legs, the front fulcrum structure comprises an adjusting cross beam and cushion blocks arranged below two ends of the adjusting cross beam; the lifting systems are arranged on the main truss, each lifting system comprises a lifting mechanism, a steel strand and a wire coil, the lifting mechanism adopts a cross-core jack, one end of the steel strand is wound on the wire coil, the other end of the steel strand penetrates through the cross-core jack and then is connected with the corresponding lifting appliance, and the two lifting appliances are fixedly connected to a segmental beam to be installed at an interval; by means of the two lifting mechanisms, the to-be-installed segmental beam can be lifted, the transverse angle of the to-be-installed segmental beam can be adjusted, suspended butt-joint installation of the to-be-installed segmental beam and the installed segmental beam is achieved, and movement of the main truss is achieved through the walking system.
