Problems solved by technology

At present, crawler cranes are generally used on the construction site of prefabricated bridges to erect prefabricated pier columns, cover beams and other substructures, which occupy a large area, require a lot of manual assistance, low construction efficiency, and cause adverse effects on surrounding traffic and environmental protection. Therefore, there is an urgent need for an integrated bridge erecting machine to simultaneously complete the erection of segmental beams, pier columns and pier top blocks
In addition, it is often necessary to hoist pier top blocks, segmental beams and pier columns during bridge construction. Since the hoisting points of each target object are different, different hoisting tools need to be used. During the construction process, the hoisting needs to be frequently disassembled and replaced. It affects the construction efficiency and construction quality, so there is an urgent need for a universal hanging

Abstract

The invention discloses a segment assembling integrated bridge girder erection machine and a construction method thereof. The segment assembling integrated bridge girder erection machine comprises a main girder overhung in the erection direction, a hanging connecting mechanism movably arranged on the main girder and a hanger detachably connected with the hanging connecting mechanism. The hanger comprises a cross beam and a pair of short beams arranged below the cross beam, the short beams are perpendicular to the cross beam and are close to the two ends of the cross beam respectively, and vertical segmental beam hanging points are arranged at the positions, close to the ends, of the short beams in a penetrating mode respectively. pier stud hanging points are arranged on the lower bottom surface of the cross beam. The machine is provided with a universal hanger, pier top blocks, segmental beams and pier studs can be hoisted, frequent disassembly and replacement of a hanger in the construction process are avoided, and the construction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of bridge construction equipment. More specifically, the present invention relates to a segment-assembled integrated bridge erecting machine and a construction method thereof. Background technique [0002] Prefabrication of on-site concrete structures in the field of bridge construction has become a trend. At present, crawler cranes are generally used on the construction site of prefabricated bridges to erect prefabricated pier columns, cover beams and other substructures, which occupy a large area, require a lot of manual assistance, low construction efficiency, and cause adverse effects on surrounding traffic and environmental protection. Therefore, there is an urgent need for an integrated bridge erecting machine to simultaneously complete the erection of segmental beams, pier columns and pier top blocks. In addition, it is often necessary to hoist pier top blocks, segmental beams and pier columns durin...
