Embodiment Construction

[0026] Such as figure 1 The large suspended beam shown includes a main beam 1 and two sets of suspension components arranged on the main beam 1 , and the two sets of suspension components are symmetrical to the center of the main beam 1 . The main beam 1 is provided with a suspension shaft 2 supporting the suspension assembly. The upper surface of the suspension shaft 2 is an upwardly protruding arc surface. The suspension assembly includes an upwardly protruding half-moon-shaped ear plate 3. It is press-fitted and connected to the suspension shaft 2 and forms a rotating pair with the arc surface. The arc surface of the suspension shaft 2 and the half-moon ear plate 3 form a revolving pair. On the one hand, the centering and self-positioning of the suspension assembly can be easily realized, which is convenient for the installation and adjustment of the suspension assembly. On the other hand, when the workpiece is hoisted and turned At this time, the suspension assembly can s...

Abstract

The invention relates to a suspension type large hanging beam. The hanging beam includes a main beam and suspension assemblies arranged on the main beam, the main beam is provided with suspension shafts, the upper surface of each of the suspension shafts is a circular arc surface, each of the suspension assemblies includes a semilunar ear plate, and the arc-shaped bottom surfaces of the ear plates are connected to the suspending shafts in a press fitting manner, and form revolute pairs together with the arc-shaped surfaces. The arc-shaped bottom surfaces of the ear plates are connected to the suspending shafts in a press fitting manner, and form the revolute pairs together with the arc-shaped surfaces, so the centering self-positioning of the installation of the suspension assemblies is conveniently realized, and the installation and the adjustment of the suspension assemblies are convenient; and the suspension assemblies can swing around the suspension shafts at a certain angle, so the pure rigid connection of the suspension shafts and the suspension assemblies in traditional technologies is avoided, the bearing condition of the hanging beam is greatly improved, and bearing change and buffer in the motion process are realized. The suspension type large hanging beam can be applied to overturn and hoist large workpieces.

Description

technical field [0001] The invention relates to a hoisting device, in particular to a suspended large suspension beam. Background technique [0002] A large workpiece has a total length of 11m, an outer diameter of 6m, and a total weight of 410T. In the final stage of manufacturing, the workpiece is turned from a horizontal state to a vertical state, so as to conduct a pre-completion inspection test. Since the structural size and total weight of the workpiece are much larger than ordinary workpieces, any accidents during the overturning of the lifting beam may directly damage the workpiece, which will become an extremely serious problem for the workpiece in the final stage of manufacturing. quality problems, so it puts forward extremely high requirements on the stability and reliability of the flipping process. [0003] During the hoisting and turning process, the workpiece is in a state of continuous motion, and the hanging beam is also in a state of continuously changing ...
