Improved anti-collision device used in hoisting process of large-scale multi-corner-angle cantilever truss

Abstract

According to an improved anti-collision device used in the hoisting process of a large multi-corner-angle cantilever truss, 5-15 rollers are movably connected in series in a U-shaped groove of a front groove plate, and the periphery of each roller is wrapped with a rubber sleeve; the rollers and the rubber sleeve are combined to form a runner wheel mechanism; 16 guide cylinders are fastened on the back face of the front groove plate in a welded mode, a rubber block is arranged in each guide cylinder, the 16 guide cylinders are arranged in four rows and four columns to form a cylinder matrix, 16 guide rods are fastened on the front side face of a rear wall plate in a welded mode, the 16 guide rods are also arranged in four rows and four columns to form a rod matrix, and the cylinder matrix can correspond to the rod matrix; each guide cylinder can correspondingly sleeve one guide rod so as to form a guide mechanism; the periphery of each guide mechanism is sleeved with a telescopic spring; and the front groove plate and the rear wall plate are connected through a spring square matrix and combined to form the telescopic anti-collision mechanism. The anti-collision device has the advantages of being novel in structure, ideal in anti-collision effect and high in practicability.

Description

technical field [0001] The invention belongs to the field of building construction auxiliary equipment, and relates to an improved anti-collision device used in the hoisting process of a large multi-angular cantilevered truss. Background technique [0002] After the large-scale multi-angular cantilever truss is welded and assembled, the whole truss is hoisted by the crane. During the process of lifting the whole truss and moving to the target position, the whole truss will not be able to move under the influence of the wind. To avoid the problem of shaking, the whole truss in the shaking state is very likely to cause damage to the stone curtain wall behind the target position during the process of advancing to the target position. Contents of the invention [0003] In order to solve the above problems, the present invention provides an improved anti-collision device used in the hoisting process of large multi-angular overhanging trusses, which has the characteristics of no...

Problems solved by technology

[0002] After the large-scale multi-angular cantilever truss is welded and assembled, the whole truss is hoisted by the crane. During the process of lifting the whole truss and moving to the target position, the whole truss will not be able to move under the influence of the wind. To avoid the problem of sloshing, the whole truss in the swaying state is very likely to cause damage to the stone curtain wall behind the target position in the process of advancing to the target position
