The invention relates to the technical field of hoisting slings, and provides a concrete prefabricated box girder rapid hoisting sling which comprises a fixed shell, a first threaded rod, a first motor, a hoisting mechanism and a bottom supporting mechanism, the first threaded rod is rotationally installed in the fixed shell, the first motor is fixedly installed on the fixed shell, and the first motor is fixedly installed on the bottom supporting mechanism; the output end of the first motor penetrates through the fixing shell to be connected with the first threaded rod, the two lifting mechanisms are arranged on the first threaded rod, the four bottom supporting mechanisms are arranged on the lifting mechanisms, the prefabricated box girder is fixed through the lifting mechanisms, and the bottom supporting mechanisms are arranged on the lifting mechanisms. According to the technical scheme, the problems that in the lifting process in the prior art, due to the fact that a rope is abraded and broken, the prefabricated box girder falls off, certain potential safety hazards are caused to workers on the ground, the rope needs to be overhauled and replaced regularly, and the lifting work efficiency is low are solved.
本发明涉及起吊吊具技术领域,提出了一种混凝土预制箱梁快速起吊吊具,包括:固定壳体、螺纹杆一、电机一、起吊机构和托底机构,螺纹杆一转动安装在固定壳体内部,电机一固定安装在固定壳体上,电机一的输出端贯穿固定壳体与螺纹杆一连接,起吊机构设置有两个,两个起吊机构设置在螺纹杆一上,托底机构设置有四个,四个托底机构设置在起吊机构上,通过起吊机构对预制箱梁进行固定,并通过托底机构分担预制箱梁对起吊机构的重量,通过上述技术方案,解决了相关技术中在起吊过程中,因为绳索磨损断裂,导致预制箱梁掉落,对地上工作者有一定的安全隐患,需要对绳索进行定期检修和更换,起吊工作效率较低的问题。
