Abstract
The invention provides an inner stator lifting and turnover structure. By the adoption of a structure that a small hook of a travelling crane is matched with a large hook for simultaneous lifting, the inner stator lifting and turnover structure guarantees perpendicular lifting of an inner stator; by the additional arrangement of an inclined base plate structure, the axes of two lifting bars can be located on the same straight line after the inner stator lifting and turnover structure is mounted, so that the requirement of turnover rotation is met; by the additional arrangement of a tightening structure, the inner stator is stressed with both the shearing force of bolts and the forward tightening force of the tightening device in the lifting and rotating turnover process; and therefore, the safety coefficient of the whole structure is greatly increased, and the service life of the whole structure is greatly prolonged.
Description
Technical field
The present invention relates to depart from the vertical lifting of station in a kind of technique for outer press mounting after inner stator completion and stand up
Structure, be easy to installing for follow-up inside and outside stator.
Background technology
Inner stator is a vitals in steam turbine generator, and it is mainly by parts groups such as stator core, vibration isolation ring cages
Into.When inner stator is assembled, first stator core is installed as into an entirety, then by vibration isolation ring cage positioning welding firmly in stator core
On so that both become an entirety.About 220 tons of the inner stator weight of 660MW double water innercooling electric generators, due to inside and outside stator
Install needs, default minor structure in the finished, need to be through vertical lifting and 90 ° of operations stood up.Traditional hoisting and overturning work
Lamps structure, will hoisting structure be directly installed on ring cage connecting plate and implement vertical lifting and stand up operation, this structural requirement
Ring cage connecting plate is in center line symmetry, and to ensure Heave Here in position of centre of gravity, and joint hinge axle is in same straight line just
Stand up in rotation.Its main deficiency has：If the 1, default subring cage connecting plate Bu centers line symmetry, can produce bias, nothing
Method forward direction vertical lifting, when station is departed from, can produce interference with station facility, auxiliary mould etc., cause to damage inner stator and produce
Product.If the 2, default subring cage connecting plate has deflection angle, cannot realize standing up operation.3rd, traditional structure is mainly connected as spiral shell
Bolt receives shearing force during hoisting and overturning closing for bolt.Because the excessive screw thread on ring cage connecting plate of local stress produces change
Shape, affects normally moving back for bolt to pull out.
For 660MW double water innercooling electric generators, its ring cage connecting plate Bu centers line symmetry, and also one
Deflection angle, according to traditional hoisting turning tool structure, both cannot vertical lifting, can not realize standing up operation.
The content of the invention
The technical problem to be solved in the present invention be the vertical lifting of the inner stator for realizing 660MW double water innercooling electric generators and
Stand up operation.
In order to solve above-mentioned technical problem, the technical scheme is that there is provided a kind of inner stator hoisting and overturning structure,
The inner stator is axially distributed multiple rings, each ring circumferentially around the inner stator one week, the circumferentially cloth on each ring
It is equipped with multiple ring cage connecting plates, it is characterised in that also including ring cage attachment means, in each side fixing for the inner stator
There are a ring cage attachment means, each ring cage attachment means is connected solid with the ring cage connecting plate for being presented axially in a row
It is fixed, dismountable joint hinge is provided with each ring cage attachment means, after the installation of ring cage attachment means is in place, two side ring cages connection dress
The axle center for putting 2 joint hinges of sustained height is located along the same line, in the ring cage connection positioned at center on front side of the inner stator
Plate is provided with little hook hanger so that the stress point of junction is placed exactly in so that the monosymmetric straight line of the inner stator center line
On, steel wire rope baffle plate is located on the ring cage connecting plate at the top of the vapour end of the inner stator, the internal structure and ring of steel wire rope baffle plate
Two inclined-planes laminating of cage connecting plate, the height of steel wire rope baffle plate just exceeds the vapour end support bar position of the inner stator.
Preferably, the ring cage attachment means include the long slab being connected with the ring cage connecting plate, long slab towards
The one side of the inner stator is provided with a row taper liner block, after causing the installation of ring cage attachment means in place by taper liner block, two side rings
The axle center of 2 joint hinges of sustained height is located along the same line in cage attachment means, equal in the lower section and side of each taper liner block
It is provided with the side being fixed on long slab to hold out against structure and hold out against structure, side holds out against structure and holds out against on the skew back face of ring cage connecting plate,
Hold out against structure to hold out against on ring.
Preferably, be provided with the ring cage attachment means per the skew back face of ring cage connecting plate described in block on be provided with pad
Bar, the side holds out against structure and holds out against on filler strip.
The present invention ensures the vertical lifting of inner stator by coordinating the structure that hook is lifted by crane using the little hook of driving simultaneously；
By increasing oblique backing structure so that the axle center of 2 joint hinges is in same straight line after installation, reaches the requirement for standing up rotation；It is logical
Cross increase and hold out against structure so that during lifting and rotation are stood up, suffered power is not only bolt shearing force to inner stator, also
There is the positive pressure of holding device, substantially increase the safety coefficient and service life of total.
It is an advantage of the invention that：Driving hook, the lifting method of little hook operation simultaneously are employed, novel electricity generator is solved
The problem that inner stator lifting bias, joint hinge axle cannot not stand up after installing in a straight line in (660MW double-water internal coolings)；Rising simultaneously
Improve on the force way for hanging, improve the safety coefficient and service life of total.

Specific embodiment
To become apparent the present invention, hereby with preferred embodiment, the present invention will be further described.
With reference to Fig. 1 and Fig. 7, in the present invention, inner stator is axially distributed multiple rings 7, and each ring 7 is circumferentially around default
Son one week, circumferentially there is multiple ring cage connecting plates 6 on each ring 7.
With reference to Fig. 1, Fig. 3 A and Fig. 3 B, a kind of inner stator hoisting and overturning structure that the present invention is provided includes ring cage attachment means
1st, joint hinge 2, little hook block ear 3, steel wire rope baffle plate 4, filler strip 5.With reference to Fig. 4 and Fig. 5, ring cage attachment means 1 include long slab 1-1, tiltedly
Cushion block 1-2, side hold out against structure 1-3 and hold out against structure 1-4.
The structure of the present invention is as follows：
With reference to Fig. 2, Fig. 4 and Fig. 5, the long slab 1-1 materials of ring cage attachment means 1 are the low-carbon alloy steel plate of high intensity, its
On be provided with counterbore, conjunction is connected on ring cage connecting plate 6 by bolt.By installing taper liner block 1-2 on long slab 1-1 so that
Ring cage attachment means 1 install it is in place after, the axle center of 2 joint hinges 2 on same straight line 9, to meet the condition stood up of rotation.Every
The side that the lower section and side of individual taper liner block 1-2 is mounted on being fixed on long slab 1-1 holds out against structure 1-3 and holds out against structure 1-4.Knot
Fig. 3 A and Fig. 3 B are closed, on the prism of the ring cage connecting plate 6 of mounting ring cage attachment means 1 filler strip 5 is mounted on.Side holds out against knot
