Air relay girder erection construction method
The invention discloses an air relay girder erection construction method which comprises the steps that a first precast beam is erected on an Nth span, and the step of erecting the first precast beam on the Nth span comprises the substeps that a first beam transporting vehicle and a second beam transporting vehicle transport the first precast beam to a beam of an (N-1) th span, and a first crane and a second crane drive into the Nth span; a detacher on the first crane is connected with a first lifting appliance at the second end of the first precast beam, and the second end of the first precast beam is lifted by the first crane; the second beam transporting vehicle runs away, and the first beam transporting vehicle runs towards the Nth span by a preset distance; the detacher on the second crane is connected with the second lifting appliance at the second end of the first precast beam, and the detacher on the first crane is automatically unhooked from the first lifting appliance at the second end of the first precast beam; a detacher on the first crane is connected with a third lifting appliance at the first end of the first precast beam, and the first crane lifts the first end of the first precast beam; and the first crane and the second crane cooperate to hoist the first precast beam to the Nth span.
本发明公开了一种空中接力架梁施工方法，包括在第N跨上架设第一预制梁，在第N跨上架设第一预制梁包括：第一运梁车以及第二运梁车将第一预制梁运输至第N‑1跨的梁上，第一吊车以及第二吊车驶入第N跨内；第一吊车上的脱钩器与第一预制梁的第二端的第一吊具连接，且第一吊车吊起第一预制梁的第二端；第二运梁车驶开，且第一运梁车朝向第N跨行驶预设距离；第二吊车上的脱钩器与第一预制梁的第二端的第二吊具连接，且第一吊车上的脱钩器与第一预制梁的第二端的第一吊具自动脱钩；第一吊车上的脱钩器与第一预制梁的第一端的第三吊具连接，且第一吊车吊起第一预制梁的第一端；第一吊车与第二吊车协同将第一预制梁吊装至第N跨上。
