Embodiment Construction

[0043] This embodiment is a tool for vertical and horizontal turning of metal shells. The metal shell has a diameter of 3000mm, a length of 6000mm, and a weight of 13t. It is assembled and welded by a skirt frame, a joint, a head and a cylinder.

[0044] This embodiment includes a spreader, a bracket, a chuck and lifting lugs. The spreader, the bracket and the chuck are independent of each other and used together. Described chuck has two pieces, is respectively first chuck 13 and second chuck 15. There are two lifting lugs, the long lifting lug 12 used with the first chuck 13, and the short lifting lug 16 used with the second chuck 15.

[0045] The hanger includes a beam 3 , two transition blocks 4 , a connecting block 5 and a wire rope 1 . Wherein, the two connecting blocks 4 are respectively hinged at both ends of the beam 3 . The upper ends of the two transition blocks are connected to the steel wire rope 1; the lower ends of the two transition blocks 4 are respectively...

Abstract

An overturning device for a large metal shell comprises a lifting appliance, a bracket, a first chuck and a second chuck, wherein the lifting appliance and the bracket are mutually independent and used cooperatively. The first chuck and the second chuck are clamped on a front skirt and a rear skirt of the metal shell respectively and are tensioned and fixed through a double-end threaded long screw along the axis, so that the chucks and the shell form a whole of a cage type structure. Then the second chuck is connected with the tripod lifting appliance and the H-shaped bracket through lifting lugs, the metal shell of the cage type structure can revolve around the lifting lugs, the heavy metal shell can be stably and safely overturned from a vertical state to a horizontal state and from a horizontal state to a vertical state in the mode that a crane pulls the tripod lifting appliance and the H-shaped bracket, and the surface of the metal shell is not damaged.

Description

technical field [0001] The invention relates to the mechanical processing industry, in particular to a vertical and horizontal turning tool suitable for heavy metal shells with a diameter of φ2000mm or more and a weight of 10t or more. Background technique [0002] The metal shell is generally a cylindrical product formed by welding joints, skirt frames, heads and cylinders. After welding, it is machined. The outer surface has high requirements for smoothness, and defects such as knocks and bruises are not allowed. The metal shell needs to be turned back and forth vertically and horizontally during the processing and turnover process. Since there are no external parts that can act on the outer surface, turning tooling must be used during the turning process. [0003] At present, the tooling and method used for vertical and horizontal flipping of metal shells are as follows: the outer circle of both ends of the metal shell is embraced by the O-shaped metal rings with rubber f...
