The utility model discloses a lifting and turning tool for a large nuclear power head forging, which comprises a base, a lifting frame, and a V-shaped positioning frame. The connecting end of the lifting frame is fixedly connected to one end of the base, and the other end of the base is movably connected to the V-shaped positioning frame; The V-shaped positioning frame includes a positioning column and a plurality of V-shaped parallel irons, and the multiple V-shaped parallel irons are evenly distributed along the height direction of the positioning column; the bottom end of the positioning column of the V-shaped positioning frame is connected to the base through a pin shaft. The utility model can complete the turning work of the head forging or the forging with the arc surface, and has simple operation, strong practicability and small risk factor.
Description
Technical field
The utility model relates to a kind of lifting frock, is specifically related to a kind of hoisting and overturning frock of large nuclear-power end socket forging.
Background technology
High-end equipment manufacture is as strategic new industry; Its principal character is large-scale, complete, advanced technology, intelligent degree high, comprehensive strong, highly difficult, high quality that design technology is made; Being the infrastructure industry that embodies the equipment manufacture comprehensive strength, is the basic industry that are related to the industrialization of the country, the modernization of national defense.
Wherein, the about φ 4300mm * 2500mm of the size of the large nuclear-power end socket forging in the AP1000 nuclear power projects, because its size super large, and shape is the bowl type, in the course of processing, utilizes existing lifting frock to be not easy lifting, more is difficult for standing up.
There is following problem in existing lifting frock:
If 1 adopts the lifting of pawl pincers, because the side of end socket forging is an arc, when lifting, come off easily, stand up in the process dangerously, and cause the forging damage easily, in the end socket forging surplus hour, cause forging to scrap probably, cause very big loss;
If 2 directly with the steel rope lifting,, need welding perhaps to adopt other modes to increase and revoke owing to end socket forging shape reason can't be fixed; Will certainly therefore place the surplus of end socket forging like this; Cause unnecessary waste, and carry out large-scale workpiece when standing up, cause the workpiece damage easily with steel rope; Operating difficulties, danger coefficient is high;
If 3 adopt the magnet-type lifting tool, hoisting weight has restriction, and can only accomplish lifting, can't accomplish large-scale workpiece and stand up.
The utility model content
The utility model technical matters to be solved provides a kind of hoisting and overturning frock of large nuclear-power end socket forging, and it can accomplish the hoisting and overturning work of large-scale bowl type workpiece.
For solving the problems of the technologies described above, the technical solution of the hoisting and overturning frock of the utility model large nuclear-power end socket forging is:
Comprise base, upending frame, V-arrangement locating rack, an end of the coupling end captive joint base of upending frame, the other end of base flexibly connects the V-arrangement locating rack; The V-arrangement locating rack comprises registration mast, a plurality of V-type parallels, and a plurality of V-type parallels are along the short transverse rectangular distribution of registration mast; The registration mast bottom of V-arrangement locating rack connects said base through bearing pin.
The free end of said upending frame is provided with hanger.
The top of said registration mast is provided with hanger.
Fixing between said upending frame and the base for welding.
Said base, upending frame, V-arrangement locating rack are respectively weldment.
The technique effect that the utility model can reach is:
All parts of the utility model all are welded by steel plate or I-beam section etc., and are easily manufactured.
Base of the utility model and V-arrangement locating rack link together through bearing pin, back-up ring, bolt, packing ring, and bearing pin connects and can rotate each other.
Be provided with hanger on upending frame of the utility model and the V-arrangement locating rack, through the height of driving adjusting upending frame or V-arrangement locating rack, can accomplish the work of standing up that end socket forging perhaps has the arcwall face forging, simple to operate, practical, danger coefficient is little.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation:
Fig. 1 is the scheme drawing of the hoisting and overturning frock of large nuclear-power end socket forging;
Fig. 2 is the birds-eye view of Fig. 1.
Description of reference numerals among the figure:
1 is base, and 2 is upending frame,
3 is the V-arrangement locating rack, and 31 is registration mast,
32 is the V-type parallels, and 4 is bearing pin,
5 is back-up ring, and 6 is bolt,
7 is packing ring, and 10 is workpiece.
The specific embodiment
Like Fig. 1, shown in Figure 2, the hoisting and overturning frock of the utility model large nuclear-power end socket forging comprises base 1, upending frame 2, V-arrangement locating rack 3, an end of the coupling end captive joint base 1 of upending frame 2, and the other end of base 1 flexibly connects V-arrangement locating rack 3;
The free end of upending frame 2 is provided with hanger;
Fixing between upending frame 2 and the base 1 for welding;
V-arrangement locating rack 3 comprises registration mast 31, a plurality of V-type parallels 32, and a plurality of V-type parallels 32 are along the short transverse rectangular distribution of registration mast 31;
V-arrangement locating rack 3 can be realized rotation with respect to base 1.
During use, workpiece 10 is positioned on the base 1 or the side (one side of band circular arc is positioned over V-arrangement locating rack 3, is beneficial to the location) of V-arrangement locating rack 3; Through the driving lifting; Regulate the height of base 1 or V-arrangement locating rack 3, accomplish standing up of large nuclear-power end socket workpiece, simple to operate.
