Hoisting and overturning method for square pyramid type equipment

Abstract

The invention belongs to the hoisting technology field. The invention discloses a hoisting and overturning method for square pyramid type equipment. A four-pipe shaft type main lifting lug is arrangedat a bottom of the square pyramid type equipment. An eccentric pipe shaft type tail slip lifting lug is arranged at an upper portion. A tail slip crane is adopted to configure a tail slip hanging balance beam and a tail slip hanging steel wire rope to lift the square pyramid type equipment. The lifted square pyramid type equipment is in an inclined state. The other main hoisting crane is provided with a rigging system which is composed of a main hoisting balance beam, a fixed pulley and a main hoisting steel wire rope. Main lifting lugs which are symmetrically distributed are hung below thesquare pyramid type equipment overturn till that the square pyramid type equipment overturns in an up-right state. Two hoisting machines are cooperated to smoothly finish 180-degree overturning of thesquare pyramid type equipment, erection of a high-altitude bearing platform is avoided, an influence of hoisting on equipment mounting quality is greatly reduced while safety is guaranteed and efficiency is improved, a process is stable and safe, and a quality perfectness ratio of the square pyramid equipment is 100%.

Description

Technical field [0001] The invention belongs to the technical field of hoisting, and in particular, relates to a hoisting and turning method for equipment with a specific shape. Background technique [0002] Pyramid equipment is large in size, complex in structure, and difficult to transport as a whole. It is often considered to be transported to the construction site of the installation area in the form of loose parts. After the planned prefabricated site is assembled into a whole, it is hoisted in place by large machinery. Generally, the function of the square pyramid type equipment is mainly to store and filter raw materials, and the installation form is that the opening faces upwards and the tip faces downwards, and is set on the high-altitude frame. When assembling on the ground, considering the convenience of construction, reducing safety risks, saving costs and other factors, it is more convenient for the construction unit or manufacturer to assemble this type of equipment...

AI Technical Summary

Problems solved by technology

[0004] The present invention focuses on solving the technical problem of difficult hoisting and turning over of square pyramid equipment with special-shaped structures, and provides a hoisting and turning method for square pyramid equipment, which adopts eccentric setting of sliding tail lifting lugs and distributed setting of main lifting lugs , wire rope misalignment setting, balance beam, pulley and other sling system settings, using two hoisting machines to successfully complete the 180° flip of the square pyramid equipment, avoiding the erection of high-altitude caps, while ensuring safety and improving efficiency, greatly The impact of hoisting on the quality of equipment installation is reduced, the process is stable and safe, and the quality of the square pyramid equipment is 100% intact
