Abstract

The invention discloses a cable-stayed sling type vertical-lifting lifting appliance having a large-stiffness frame structure and an assembled lifting appliance, and relates to the cable-stayed sling type vertical-lifting lifting appliance used for vertically lifting products and the assembled lifting appliance. The vertical-lifting lifting appliance includes an overall lifting appliance and a lifting basket; the whole lifting appliance comprises a frame surrounded by two first beams and two second beams, and joints of the four beams are used as lifting points; the lifting basket is formed by connecting two semi-baskets, and the lower parts of the semi-baskets are provided with a plurality of bearing beams for bearing the products; lifting rings comprise an upper lifting ring and two lower lifting rings which are respectively buckled with the upper lifting ring, each lower lifting ring is connected with two shackles, and each shackle is connected with one upper lifting belt; the upper lifting belts are connected together with the frame through upper hitch yokes and pin shafts; lower lifting belts are connected with the frame through lower hitch yokes, the other end of each lower lifting belt is connected with one of four integral lifting lugs arranged on the semi-baskets; the distance between each two integral lifting lugs is equal to the distance between each two corresponding lifting points. The assembled lifting appliance also adopts the frame structure for lifting products.

Description

technical field [0001] The invention relates to a sling, in particular to a cable-stayed sling type vertical lifting sling for vertically lifting products and an assembly sling. Background technique [0002] When the product is hoisted vertically with a single hook, it is required that the angle between the axial direction and the vertical direction of the product is not more than 3 degrees, and the lifting device must not generate additional radial force on the product. The lifting condition of the product is different from the force condition in the actual use stage. While satisfying the lifting condition of the product, the working condition of the actual use must also be considered, so as not to affect the performance of the product. When the lifting product is a star cover assembly or other payloads carried by rockets, there are also strict restrictions on the weight of the product, and the weight of the product must not be increased. [0003] Usually, the lifting lug ...
