Spatial two-moment distribution hoisting method of overweight body with partial gravity centre

Abstract

The invention discloses a spatial two-moment distribution hoisting method of an overweight body with a partial gravity centre. The method comprises the following steps of simulating and calculating a hoisting system by using a computer; determining a working area of cranes; starting the crane A and the crane B; hoisting the overweight body with the partial gravity centre to a certain height above ground; turning around the big arms of the crane A and the crane B to hoist the overweight body out of a pit; adding two flexible straps to be respectively bound at the head part and the tail part of the overweight body with the partial gravity centre, and starting the crane C and the crane D simultaneously; rotating the straps of the crane A and the crane B to a predetermined angle, hoisting the overweight body by the crane A and the crane B at the same time, and rotating the two moments; placing the overweight body on a transport vehicle after side sideways turning the overweight body; and reversely repeating step 3 to step 7 after transporting the overweight body to a destination. By the method disclosed by the invention, the problems that hoisting and falling are unstable when a traditional stand-alone large tonnage crane hoists the overweight body with the partial gravity centre, the overweight body cannot be transported smoothly when being vertically placed on the transport vehicle and the appearance of the overweight body is damaged when the overweight body is bound by using a steel wire rope are solved.

Description

technical field [0001] The invention belongs to the field of load hanging, in particular to a space hoisting method for an overweight artwork with an eccentric center of gravity. Background technique [0002] With the rapid development of the city, more and more large-scale works of art have been brought into urban life, and large-scale works of art placed in public places have become part of the achievements of urban public cultural construction. The production of these works of art requires processes such as production, transportation, and installation. The installation process may encounter the following problems: [0003] 1. The traditional structure with a regular shape and center of gravity does not deviate. The hoisting process generally uses a single large-tonnage crane to lift and fall vertically. Since there is only one lifting point, it is necessary to accurately determine the position of the center of gravity, and the suspension point must be directly above the c...

Problems solved by technology

[0006] The purpose of the present invention is to provide a two-point moment distribution hoisting method for an eccentric center of gravity superheavy body space, which solves the problem of unstable lifting and falling when a traditional single-machine large-tonnage crane hoistes an eccentric center of gravity superheavy body, and cannot be transported smoothly when placed on a transport vehicle in a standing position and adopts Technical problems that damage the appearance when the wire rope is tied
