Abstract
The invention relates to a hoist balancing frame of a cross-flow generator stator, which is characterized in that hoist plates are articulated at both ends of a cross beam; the lower ends of the hoist plates are provided with holes which are connected with stator machine bases; the cross beam is a rectangular vertical plate; an upper cover plate and a lower support plate are respectively welded at the upper side edge and the lower side edge of the vertical plate; vertical rib plates which are connected with the upper cover plate and the lower support plate are uniformly distributed and welded at the front and the back of the vertical plate; the vertical plate is provided with two hoist holes which are in symmetry with a center line; and adjusting helical sleeves which are connected with small hoist rings of the stator machine base are articulated on the vertical rib plates in the middle of the cross beam. By hoisting the stator machine base by the cross beam and the hoist plates, the centripetal tensile force at both sides of the stator machine base is eliminated, and the deflection amount of the stator machine base is reduced; in addition, the adjusting helical sleeves which are connected with the small hoist rings at the upper side of the stator machine base are articulated on the vertical rib plates in the middle of the cross beam, the rotation of the stator machine base is limited, and the hoist is more stable and safe; and in addition, the invention also has the advantages of simple structure, good process property, easy manufacture, low cost and obvious effect.
Description
Technical field
The present invention relates to a kind of hoist balancing frame of cross-flow generator stator.
Background technology
No matter generator unit stator is at workshop or all needs integral hoisting at the construction field (site).The key issue of integral hoisting is safe and reliable and reduces the distortion of out frame.Because stator the time has very big stress on support in lifting, so during the stator integral hoisting, make realistic plan according to the factors such as total weight of out frame rigidity, diameter and stator.Otherwise the distortion of support will make iron core be squeezed and stretch, and produce distortion.This will directly cause the destruction of fixed subcoil insulating, can cause the motor short circuit when serious.
The integral hoisting scheme of known tubular-turbine generator stator is the steel rope lifting; Promptly satisfy two steel ropes of force request with diameter, an end of two steel ropes is hung on the two ends suspension ring of out frame, the two steel rope other ends hang on the main hook of crane and lift by crane.Single-machine capacity was less and the stator frame wall design-calculated is thicker in the past, and stator diameter is generally below 5 meters, thereby under lifting personnel's meticulous operation, lifting meets the demands basically.
Along with the demand of electricity market, the single-machine capacity of tubular-turbine generator develops into tens thousand of kW by several thousand kW at present, and stator diameter is also near 10m, and the total weight of stator is more than hundred tons.And steel rope when lifting out frame both sides and lower half circle entad receive pulling force and gravity downwards respectively, and it is bigger that out frame is out of shape; In addition, both sides hang the steel rope lifting and can not limit out frame and rotate, and usually occur skew during lifting, make difficult installation.
Summary of the invention
The present invention provides a kind of hoist balancing frame of cross-flow generator stator steady, that distortion is little that lifts by crane for solving the technical matters that exists in the known technology.
The technical scheme that the present invention takes for the technical matters that exists in the solution known technology is:
A kind of hoist balancing frame of cross-flow generator stator; Comprise crossbeam, be hinged on the boatswain chair that rises at crossbeam two ends; Play the boatswain chair lower end and be shaped on and out frame bonded assembly hole, said crossbeam is a rectangle riser, and the upper side edge of riser and lower side are welded with upper cover plate and bottom plate respectively; The front and back of riser is uniformly distributed with and is welded with and upper cover plate and bottom plate bonded assembly vertical rib plate, is shaped on two lifting eyes of symmetrical center line on the riser.
The present invention can also adopt following technical scheme:
The front and back of said lifting eye is welded with ring flat-plate, and the inside circumference of ring flat-plate is shaped on fillet.
Be welded with the back plate of lifting eye between said upper cover plate and the riser, the cross-sectional plane of back plate is a J-shaped.
The hole of said boatswain chair lower end is a Pear-Shaped.
Be hinged with and the little suspension ring bonded assembly of out frame upside adjustable screw cover on the vertical rib plate in the middle of the said crossbeam.
Advantage and good effect that the present invention has are:
Owing to adopt crossbeam and boatswain chair to lift out frame, eliminated the entad pulling force of out frame both sides, reduced the deflection of out frame; On the vertical rib plate in the middle of the crossbeam, be hinged with and the little suspension ring bonded assembly of out frame upside adjustable screw cover in addition, define the rotation of out frame, make that lifting is steady more, safety; The present invention also has simple in structure, good manufacturability, is easy to make in addition, low, the outstanding effect advantage of cost.

The specific embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, the following examples of giving an example now, and conjunction with figs. specifies as follows:
Like Fig. 1, shown in Figure 2; Crossbeam is a rectangle riser 1; The upper side edge of riser and lower side are welded with upper cover plate 14 and bottom plate 15 respectively; The front and back of riser is uniformly distributed with and is welded with and upper cover plate and bottom plate bonded assembly vertical rib plate 12, on the vertical rib plate 6 in the middle of the crossbeam, is hinged with and the little suspension ring 16 bonded assembly adjustable screws cover 18 of out frame 9 upsides through connecting panel 17 and pin 19, and is as shown in Figure 3.Be shaped on two lifting eyes 7 of symmetrical center line on the riser; The front and back of this lifting eye is welded with ring flat-plate 13; The inside circumference of ring flat-plate is shaped on fillet; Be welded with the back plate 11 of lifting eye between said upper cover plate and the riser, the cross-sectional plane of back plate is a J-shaped, so that the slick and sly surface of steel rope 20 contacts is without prejudice.Be hinged with boatswain chair 2,5 at the crossbeam two ends through hinge 3,4, played the boatswain chair lower end and be shaped on and out frame suspension ring 8,10 bonded assembly holes 21, this hole of playing the boatswain chair lower end is a Pear-Shaped, is convenient to loading and unloading.The position that will depart from stator center of gravity G during the suspension ring design is that (about 30mm～50mm), its objective is the error of aspects such as must exempting from material, construction, manufacturing, the weight of increase upstream side make the supported at three point lifting safer to e.During lifting steel rope 20 1 ends are passed lifting eye, the other end hangs over just can implement lifting on the main hook.The positive and negative bolt of adjustment screw-casing makes axis stator maintenance level in the time of lifting.After the adjustment screw-casing centering axis horizontal, stator will keep this state can not squint.The lifting process is steady, safe and reliable, guarantees that the out frame distortion is in the designing requirement scope.Like this,, eliminated the entad pulling force of out frame both sides, reduced the deflection of out frame owing to adopt crossbeam and boatswain chair to lift out frame; On the vertical rib plate in the middle of the crossbeam, be hinged with and the little suspension ring bonded assembly of out frame upside adjustable screw cover in addition, define the rotation of out frame, make that lifting is steady more, safety; The present invention also has simple in structure, good manufacturability, is easy to make in addition, low, the outstanding effect advantage of cost.
