Tail lifting lug structure and construction method suitable for thin-wall slender equipment

Abstract

The invention belongs to the technical field of lifting lugs, and discloses a tail lifting lug structure and construction method suitable for thin-wall slender equipment. The tail lifting lug structure comprises two tubular shaft type tail-slipping lifting lugs which are arranged in the axial direction of an equipment barrel in an up-down spaced mode, and the two tubular shaft type tail-slipping lifting lugs are symmetrically arranged in the radial direction of the equipment barrel. The two tubular shaft type tail-slipping lifting lugs are the same in structure, lifting lug tubular shafts are welded to a reinforcing plate through a first vertical plate and a second vertical plate, and the reinforcing plate is welded to the equipment barrel. The first vertical plate is arranged at one ends of the lifting lug tubular shafts, outer check rings are arranged at the other ends of the lifting lug tubular shafts, and the second vertical plate is arranged between the first vertical plate and the outer check rings. According to the construction method, the two tubular shaft type tail-slipping lifting lugs are connected with the two ends of a steel wire rope hung on a pulley, and the pulley is connected with a rigging hung on a lifting hook of a tail-slipping crane. According to the tail lifting lug structure and construction method suitable for the thin-wall slender equipment, the stress points of the tail lifting lugs are increased, stress concentration is reduced, so that stress is uniformly distributed when the thin-wall slender equipment is lifted, and the overall lifting requirement is met.

Description

technical field [0001] The invention belongs to the technical field of hoisting lugs, and in particular relates to a tail lug structure and a construction method suitable for thin-walled and elongated equipment. Background technique [0002] The slenderness ratio of thin-walled and slender equipment is large. When the equipment is hoisted as a whole, the deflection deformation has a great impact on the equipment. Excessive deflection deformation will cause plastic deformation of the equipment, and even cause the lining material of the equipment to fall off. [0003] In order to prevent the influence of deflection and deformation on the hoisting of the equipment, multiple lifting lugs are usually installed on the equipment body for hoisting. In the prior art, four pipe-type main lugs and two or a single plate-type tail lug are used for hoisting. However, with the advancement of technology, the scale of device construction is getting larger and larger, and the specifications ...

AI Technical Summary

Problems solved by technology

However, with the advancement of technology, the scale of equipment construction is getting larger and larger, and the specifications and sizes of large equipment are gradually increasing. The existing technology can no longer meet the hoisting requirements of thin-walled and slender equipment with increasing slenderness ratio.
