The invention discloses a steel structure lifting device for road bridge and building construction and a construction method, and relates to the technical field of building construction. According to the steel structure lifting device for road bridge and building construction and the construction method, the steel structure lifting device comprises a lifting crane, a base is fixedly connected to the top of the lifting crane, a telescopic lifting column is rotationally connected to the interior of the base, and an alarm mechanism is arranged on one side of the outer portion of the telescopic lifting column; the alarm mechanism comprises a connecting piece, and the connecting piece is fixedly connected to one side of the outer end of the telescopic lifting column. According to the steel structure lifting device for road, bridge and building construction and the construction method, through the design of the alarm mechanism, due to the fact that a rope is broken, the rope can be separated from the alarm, the alarm starts to extend towards the outer portion of the connecting cylinder when not subjected to pressure of the rope, and meanwhile the alarm can give an alarm and sound; therefore, surrounding workers are reminded that the rope is suddenly broken and needs to leave the scene, and unnecessary casualties are prevented.

    本发明公开了道路桥梁和建筑施工用的钢结构起吊装置及施工方法,涉及建筑施工技术领域。该道路桥梁和建筑施工用的钢结构起吊装置及施工方法,包括起吊车,所述起吊车顶部固定连接有底座,所述底座内部转动连接有伸缩起吊柱,所述伸缩起吊柱外部一侧设有鸣警机构;所述鸣警机构包括:连接件,所述连接件固定连接于伸缩起吊柱外端一侧。该道路桥梁和建筑施工用的钢结构起吊装置及施工方法,通过鸣警机构的设计,由于绳索已然发生断裂,所以绳索会脱离报警器,报警器在不受到绳索的压力时,会开始向连接筒外部延伸,同时报警器会报警鸣音,以提醒周边的工作人员绳索突发性断裂,需要离开现场,防止造成不必要的人员伤亡。
