Hoist balancing frame of cross-flow generator stator

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 weldedat 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 islimited, 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 [0001] The invention relates to a stator lifting balance frame of a tubular generator. Background technique [0002] The generator stator needs to be hoisted as a whole no matter in the production workshop or on the construction site. The key issues of overall hoisting are safety and reliability and reducing the deformation of the stator frame. Since the stator has a great stress on the frame when it is hoisted, when the stator is hoisted as a whole, it is necessary to formulate a feasible plan according to factors such as the stiffness of the stator frame, the diameter of the stator, and the total weight of the stator. Otherwise, the deformation of the base will cause the iron core to be squeezed and stretched, resulting in deformation. This will directly lead to the destruction of the stator coil insulation, and in severe cases, it will cause a short circuit of the motor. [0003] The overall hoisting scheme of the known tubular hydroelectric generator s...

Problems solved by technology

When the wire rope is hoisted, the two sides of the stator base and the lower semicircle are respectively subjected to centripetal tension and downward gravity, which causes the stator base to deform greatly; in addition, the lifting of the wire rope on both sides cannot limit the rotation of the stator base, and deviation often occurs during hoisting , making installation difficult
