The invention relates to a steel pipe lifting appliance for building construction. According to the technical scheme, the steel pipe lifting appliance comprises a supporting frame, a threaded rod is installed on the supporting frame, the two ends of the threaded rod are each provided with a supporting plate in a screwed manner, the front end and the rear end of each supporting plate are each fixedly provided with a reel, two parallel chains are arranged below each set of reels, the ends of the chains are each provided with a supporting rod, and the chains are rotationally installed on the corresponding supporting rods. A hinge shaft is arranged on each chain ring, the hinge shafts cannot rotate relative to protruding parts of the chain rings and can only slide left and right, the hinge shafts can slide relative to concave parts of the chain rings and can also rotate relative to the concave parts of the chain rings, an installation cavity is fixed to the outer end of the concave part of each chain ring, and a sliding block is installed in the installation cavity in a sliding and attached manner. One end of each sliding block is fixedly connected with the corresponding hinge shaft, a spring is fixed to the other end of each sliding block, the free ends of the hinge shafts of the two corresponding chain rings in the left chain and the right chain are fixedly connected through pull ropes, and the supporting rods on the reels are connected through ropes.
本发明涉及一种建筑施工用钢管吊装吊具;其解决的技术方案包括支撑架,支撑架上安装有一个螺纹杆,螺纹杆的两端各旋装有一个支撑板,支撑板的前后端两各固定有一个卷盘,每组卷盘的下方设有两条平行的链条,链条的端部各设有一个支撑杆,链条转动安装在对应的支撑杆上,每个链环上设有一个铰接轴,铰接轴与链环的突出部不能发生相对转动只能左右滑动,铰接轴与链环的凹陷部既能发生相对滑动有能发生相对转动,每个链环凹陷部的外端固定有一个安装腔,安装腔内滑动贴合安装有一个滑块,滑块的一端与铰接轴固定连接,另一端固定有一个弹簧,左右两个链条中相对应的两个链环的铰接轴的自由端经拉绳固定连接,每个卷盘上支撑杆经绳索连接。
