A hoisting and flipping method for square pyramid equipment

Abstract

The invention belongs to the technical field of hoisting, and discloses a hoisting and turning method for square pyramid equipment, in which a four-pipe shaft type main lifting lug is arranged at the bottom of the square pyramid type equipment, and an eccentric pipe shaft type sliding tail hanger is arranged on the upper part For the ear, the tail-slip crane is equipped with the balance beam of the tail crane and the wire rope of the tail crane to lift the square pyramid equipment, and the pyramid equipment is in a tilted state after lifting, and the other main crane is equipped with the balance beam of the main crane, the fixed pulley and the main The rigging system composed of hanging wire ropes is tied to the symmetrically distributed main lifting lugs below the square pyramid equipment, and turned over with the trend until the square pyramid equipment is upright and completes the overturn. The present invention uses two hoisting machines to successfully complete the 180° flip of the square pyramid-type equipment, avoiding the erection of high-altitude caps, while ensuring safety and improving efficiency, it greatly reduces the impact of hoisting on the quality of equipment installation, and the process is stable and safe. , The quality of the square pyramid equipment is 100% intact.

Description

technical field [0001] The invention belongs to the technical field of hoisting, and in particular relates to a hoisting and flipping method for equipment of a specific shape. Background technique [0002] Pyramid-type 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 in the installation area in the form of loose parts. After being assembled into a whole in the planned prefabricated site, it is hoisted in place by large machinery. Usually, the function of square pyramidal equipment is mainly to store and filter raw materials, and the installation form is that the opening is facing upwards and the tip is facing downwards, and it is set on a high-altitude frame. When assembling on the ground on site, 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 ...
