Problems solved by technology

The problem with this structure is that since the lifting lugs 5 are respectively fixed at the three vertices of the triangular connector 1, when targeting irregularly rigid workpieces, the positions to be hung on the workpiece are often asymmetrical. If the lifting lugs cannot Adaptive adjustments will make the lower hook connected to it unable to accurately hang the workpiece, so the existing structure has limitations in use

Abstract

The invention provides a sling type lifting tool. According to the sling type lifting tool, a workpiece can be hung reliably, and high adaptability is achieved. The sling type lifting tool comprises a lifting ring, three upper slings, three lower slings, lifting lugs and hooks. The upper ends of the upper slings are connected to the lifting ring, and the lower ends of the upper slings are connected to a connecting piece through the lifting lugs. The upper ends of the lower slings are connected to the connecting piece through the lifting lugs, and the lower end of each lower sling is connected with the corresponding hook. The sling type lifting tool has the beneficial effects that the connecting piece is annular, and the annular connecting piece is sleeved with the lifting lugs in a sliding manner.

Description

technical field [0001] The invention relates to a hoisting sling, which is mainly used for hoisting ring-shaped or circular workpieces, in particular to a sling-type sling. Background technique [0002] The existing spreader for hoisting annular or circular workpieces is a triangular spreader, see figure 1 , including triangular connector 1, suspension ring 2, upper sling 3, lower sling 4, lifting lug 5, and hook 6. During use, suspension ring 2 is hung on the hook of the crane, and hook 6 is fixed on the ring or circular workpiece. The problem with this structure is that since the lifting lugs 5 are respectively fixed at the three vertices of the triangular connector 1, when targeting irregularly rigid workpieces, the positions to be hung on the workpiece are often asymmetrical. If the lifting lugs cannot Making adaptive adjustments will make the lower hook connected to it unable to accurately hang the workpiece, so the existing structure has limitations in use. Contents...
