Hanger capable of adjusting lifting point according to position of center of gravity of hung object an application method of hanger

Abstract

The invention relates to a hanger capable of adjusting a lifting point according to the position of the center of gravity of a hung object and an application method of the hanger. The hanger comprisesa cross beam, a lifting plate and four hanger rods, the lifting plate is connected to the upper end of the cross beam in the length direction of the cross beam in a sliding fit mode and can be lockedand fixed to the cross beam by a locking mechanism. The lifting plate is vertically installed and is provided with a hanging hole penetrating the surface of a plate, and the hanging hole is connectedwith the lifting end of a lifting mechanism, the length of the four hanger rods is adjustable, and the top ends of the four hanger rods are separately hung on the front side surface and rear side surface of the left end and the right end of the cross beam, the bottom ends of the four hanger rods are separately hung on the left side and the right side of a lifting tray, and the lifting tray is used for supporting the hung object. The lifting plate can be flexibly adjusted to the position of the gravity center of the hung object or the position close to the gravity center according to the simulated gravity center position of the hung object, and the problem of lifting eccentricity when the hung object is hung is effectively solved.

Description

technical field [0001] The invention relates to a sling, in particular to a sling capable of adjusting a lifting point according to the position of the center of gravity of an object to be hoisted and a method for using the same. Background technique [0002] When hoisting a product, it often happens that the center of gravity of the product is not the center of its geometric structure. Before hoisting, it is necessary to accurately simulate the position of the center of gravity of the product, and adjust the lifting gear and lifting points according to the simulated position of the center of gravity of the product to meet the hoisting requirements. In practical applications, the center of gravity of the product sometimes deviates greatly from the center of its geometric structure. Even if the simulation is accurate, the designed lifting point position will deviate greatly from the center of gravity of the product, causing the product to be heavy when hoisting, which not only...

[0002] When hoisting a product, it often happens that the center of gravity of the product is not the center of its geometric structure. Before hoisting, it is necessary to accurately simulate the position of the center of gravity of the product, and adjust the lifting gear and lifting points according to the simulated position of the center of gravity of the product to meet the hoisting requirements. In practical applications, the center of gravity of the product sometimes deviates greatly from the center of its geometric structure. Even if the simulation is accurate, the designed lifting point position will deviate greatly from the center of gravity of the product, causing the product to be heavy when hoisting, which not only affects the hoisting effect but also poses safety hazards For example, a combined transformer usually includes a transformer, a high-voltage room and a low-voltage room. Its structure is mainly arranged in the shape of "mesh" or "H". Its weight is mainly concentrated in the transformer room and low-voltage room, and its center of gravity deviates greatly from the center of the geometric structure, so it is difficult to determine the optimal position of the lifting point during hoisting

In addition, due to the different volumes of different objects to be hoisted, it is necessary to select different spreaders and wire ropes (or slings) of different sizes according to the actual hoisting situation, so that the factory generally keeps a variety of slings and wire ropes (or slings) of various lengths. ), high spreader cost
