The invention relates to a universal joint lifting appliance for bearing based on a U-shaped steel sling, and belongs to the technical field of lifting appliances. The universal joint lifting appliance comprises an upper lifting appliance and a lower lifting appliance, and a universal joint for adjusting the rotating angles of the upper lifting appliance and the lower lifting appliance is arrangedbetween the upper lifting appliance and the lower lifting appliance; the universal joint comprises a first pin shaft connected to the upper lifting appliance, a second pin shaft connected to the lower lifting appliance, and the U-shaped steel sling used for connecting the first pin shaft and the second pin shaft, wherein the first pin shaft and the second pin shaft are adjacently arranged, and the axes of the first pin shaft and the second pin shaft are perpendicular to each other; and the upper end of the U-shaped steel sling is rotationally connected with the first pin shaft, and the lowerend of the U-shaped steel sling is rotationally connected with the second pin shaft. According to the lifting appliance, a cross shaft is replaced by the first pin shaft and the second pin shaft whichare adjacent, are connected through the U-shaped steel sling and are crossed in space, and the lifting appliance has the advantages of being high in bearing capacity, definite in stress, easy to manufacture and low in cost on the premise that flexible connection between the lifting appliance and a lifted object is achieved.
本申请涉及一种基于U形钢吊带的承重用万向节吊具,属于起重吊具技术领域,包括:上吊具和下吊具,上吊具和下吊具之间设有调整上吊具和下吊具转角的万向节;万向节包括连接在上吊具上的第一销轴、连接在下吊具上的第二销轴,第一销轴和第二销轴相邻设置且轴线相互垂直;以及,用于连接第一销轴和第二销轴的U形钢吊带,U形钢吊带的上端与第一销轴转动连接,U形钢吊带的下端与第二销轴转动连接。本申请的吊具采用两根相邻的、通过U形钢吊带相连且在空间上十字交叉的第一销轴和第二销轴来代替十字轴,在实现吊具与被吊物柔性连接的前提下,具有承重能力强、受力明确、制作简单、成本低的优点。
