Turnover device

Abstract

According to the technical scheme, the overturning table comprises a bottom plate, a first V-shaped limiting structure and a sliding block are arranged on the bottom plate, and the first V-shaped limiting structure and the locked sliding block fix a workpiece in the radial direction; a buckle plate is further arranged on the bottom plate, and the buckle plate is used for axially fixing the workpiece; the overturning table further comprises a cantilever, and a second V-shaped limiting structure is arranged at the free end of the cantilever. And the two ends of the saddle clamp are connected with the free ends of the cantilevers, and an ejector rod arranged on the saddle clamp, the second V-shaped limiting structure and the ejector rod conduct radial positioning on the other position of the workpiece. After a workpiece is fixed on the overturning table through the structure, the overturning table is driven by the power device to rotate, so that the horizontal state and the vertical state of the workpiece are switched back and forth. Compared with a crown block and manual assistance to complete workpiece overturning, the overturning equipment provided by the invention has the advantages of extremely little manpower participation, small operation difficulty and high efficiency.

Description

technical field [0001] The invention belongs to the technical field of material handling devices, and in particular relates to a turning device. Background technique [0002] The bearing chamber of the main shaft (with rotatable bearing seat) for wind turbines is divided into seven specifications, with and without bearings, a total of 14 states, the maximum mass is 55 tons, the lengths vary from 3425mm to 4400mm, and the shapes are different And the center of gravity is different. Before the main shaft of the wind power workshop is assembled, the main shaft bearing chamber is hoisted to the station by the crane, which is in a vertical state. When assembling, the main shaft bearing chamber should be turned over 90 degrees to a horizontal state. This work was previously completed by the crane and manual assistance. Because the workpiece quality is very large, the operation is very difficult, the efficiency is low, and there is a certain risk. SUMMARY OF THE INVENTION [00...

AI Technical Summary

Problems solved by technology

Before the assembly of the main shaft in the wind power workshop, the main shaft bearing chamber is hoisted by the crane to the station, which is in a vertical state. During assembly, the main shaft bearing chamber must be turned over 90 degrees to a horizontal state. This work was previously completed by the crane and manual assistance. Due to the very large mass of the workpiece, the operation is very difficult, the efficiency is low, and it is dangerous
