Large-sized rotor shaft tilting unit

Abstract

A large-sized rotor shaft tilting unit comprises a tilting mechanism, an axial positioning mechanism, a plurality of axial sliding mechanisms, a plurality of radial positioning and clamping mechanisms. The tilting mechanism comprises a support, a rotary shaft block, a lifting cylinder, an end connecting plate and double track beams disposed in parallel. The rotary shaft block is mounted on the support. The rotary shaft block is in torsional connection with the double track beams or is in torsional connection with a portal frame fixed on the double track beams. The axial sliding mechanisms are all slidably mounted on the double track beams. Each radial positioning and clamping mechanism is disposed on one axial sliding mechanism. The lifting cylinder is supported at one ends of the double track beams and is fixed on the support. The end connecting plate is perpendicularly fixed to the other ends of the double track beams. The axial positioning mechanism is disposed on the end connecting plate. The large-sized rotor shaft tilting unit allows for automatic radial centering, automatic radial clamping, automatic axial positioning and automatic tilting according to intrinsic parameters and structural features of the rotor shaft, so that the history of tilting by travelling cranes is ended.

Description

technical field [0001] The invention relates to a large-scale rotor shaft turning device, which is suitable for turning over large-diameter shaft parts, and specifically relates to the technical field of large-size nuclear power equipment, large-scale mining machinery and other shaft parts with large diameters. Background technique [0002] Cranes are special equipment dedicated to the lifting, landing, transportation, loading and unloading of indoor and outdoor items, and have strict operating technical specifications. Vertical lifting of the hook load is a basic requirement. In the actual use of cranes in our country, for the hoisting of pole-like items, one end of the item is often used as a fulcrum, and the other end is cable-stayed. The item is eccentrically turned over at a certain angle. Crane hooks do non-standard operations such as cable pulling, pulling, and throwing, resulting in derailment, rope chaos, tipping, and falling of the crane due to the impact load exc...

AI Technical Summary

Problems solved by technology

Nuclear power rotor shafts are expensive and have higher safety requirements

Flipping by a crane is a safety hazard

Therefore, it is urgent to replace the crane overturning items with a new rotor shaft overturning scheme without safety concerns
