When the nuclear power product container is integrally transported, a large lifting beam is used, and the rated load exceeds more than 300T. Considering the characteristics of large and heavy sizes of all assembly connecting parts and components, difficulty in controlling assembly intervals and the like, workers are troublesome to overcome for series assembly and fixation work among the hanging beam, the sling head and the pin shaft.
According to the actual structure of the product, the container 60 is conventionally hoisted in an integral horizontal installation mode, two steel wire ropes 51 encircle the cylinder body of the container 60, and rope heads 52 at two ends of the steel wire ropes 51 are placed at the high part of the cylinder body of the container 60 through a tool support 70 (as shown in figure 1). The purpose of this arrangement is to enable efficient assembly of the main beam 10 to the cable head 52 by means of the pin 80 (see fig. 2). However, the difficulty of the assembly is that the matching of the distance sizes of the L1 and the L2 is difficult to guarantee, and the distance between the L1 holes is guaranteed by machining on the main beam 10 and meets certain precision requirements. However, the hole spacing size of the L2 is completely established on the randomness of cold-work assembly, and the outer circle of the pin shaft 80 and the inner circle of the hole have certain matching precision, so that when the size between the L1 and the L2 is large, a worker cannot easily adjust the hole shaft in place for assembly, and the whole weight of the combined rope head 52 reaches hundreds of kilograms, so that the assembly difficulty of the worker is increased.
