Description

Auxiliary tool for assembling generator rotor

Technical Field

The utility model relates to a generator rotor assembly, specific generator rotor assembly auxiliary fixtures that says so belongs to generator rotor assembly equipment technical field.

Background

The generator rotor hoisting is one of the most important operation steps for installing the rotor into the generator, and the quality of the generator rotor and the accuracy requirement in the installation process greatly increase the difficulty of the hoisting assembly operation.

In the prior art, when a generator rotor is hoisted, a sleeve and a binding band are fixed on a rotor main shaft, and then the whole rotor is hoisted. Although the tool can ensure the stability of the generator rotor during hoisting, the use is too troublesome, and the required tool operation field is very large; meanwhile, the horizontal position and the axial angle of the generator rotor are inconvenient to adjust during installation, additional procedures are needed for adjustment, and the offline progress of the whole generator is slowed down.

Disclosure of Invention

An object of the utility model is to overcome above-mentioned weak point to a generator rotor assembly auxiliary fixtures is provided, the assembly is lifted by crane to realization generator rotor that can convenient and stable swift, and installation operating space is little, can be applicable to the generator rotor assembly of different specifications.

According to the utility model provides a technical scheme, generator rotor assembly auxiliary fixtures includes the gallows of L shape structure, characterized by: the hanger comprises a transverse beam and a vertical beam, wherein the transverse beam is transversely arranged, one end of the transverse beam and one end of the vertical beam are connected to form a whole, and a plurality of hanging holes are formed in the hoisting end of the transverse beam; the lower end of the vertical beam is welded with a fixed cylinder; and an operating handle is welded at one side of the middle part of the vertical beam back to the cross beam and is perpendicular to the vertical beam.

Furthermore, the length of the cross beam is larger than that of the vertical beam,

furthermore, a plurality of lifting holes are uniformly distributed along the length direction of the cross beam.

Furthermore, a hanger reinforcing rib plate is welded between the cross beam and the vertical beam, and the hanger reinforcing rib plate is connected with the cross beam and the vertical beam to form a triangular supporting structure.

Further, the left side and the right side of the vertical beam and the fixed cylinder are welded with cylinder reinforcing plates.

Compared with the prior art, the utility model has the advantages that:

the utility model has the advantages of simple and compact structure, rationally, can convenient and stable swift realization generator rotor lifts by crane the assembly, installation operating space is little, can be applicable to the generator rotor assembly of different specifications.

Description of reference numerals: 1-beam, 2-vertical beam, 3-hanger reinforcing plate, 4-operating handle, 5-fixed cylinder, 6-cylinder reinforcing plate and 7-lifting hole.

Detailed Description

The invention will be further described with reference to the embodiments shown in the drawings to which:

as shown in figures 1-2, the utility model discloses mainly include the gallows of L shape structure, the gallows is including the crossbeam 1 of horizontal setting and the perpendicular roof beam 2 of vertical setting, and crossbeam 1 one end is connected with perpendicular 2 one ends of roof beam and is formed a whole.

The length of the cross beam 1 is larger than that of the vertical beam 2, a plurality of lifting holes 7 are formed in the lifting end of the cross beam 1, and the plurality of lifting holes 7 are evenly distributed along the length direction of the cross beam 1. When the crane lifting ring is used, the crane lifting ring is connected into one of the lifting holes, and the selection of the lifting hole is different according to different types of the generator rotors.

The lower end of the vertical beam 2 is welded with a fixed cylinder 5, and the fixed cylinder 5 is internally used for inserting a rotor driving end of a generator. Erect roof beam 2 and the 5 left and right sides welding barrel reinforcing plate 6 of a fixed section of thick bamboo, barrel reinforcing plate 6 can improve the joint strength between erecting roof beam 2 and a fixed section of thick bamboo 5.

The middle part of the vertical beam 2 back to one side of the cross beam 1 is welded with an operating handle 4, the operating handle 4 is perpendicular to the vertical beam 2, and when the vertical beam is used, the hanging bracket can be conveniently moved through the operating handle 4.

And a hanger reinforcing rib plate 3 is welded between the cross beam 1 and the vertical beam 2, and the hanger reinforcing rib plate 3 is connected with the cross beam 1 and the vertical beam 2 to form a triangular supporting structure.

The utility model discloses utilize lever principle, simple to use but firm structure lifts generator rotor steadily horizontally, can make things convenient for generator rotor to install through operation that angle regulation wantonly moreover.

The utility model discloses a theory of operation is: when the generator rotor is hoisted, the shaft head of the driving end of the rotor is inserted into the fixed cylinder, the hoisting ring of the travelling crane is connected with one hoisting hole in the cross beam, and the whole rotor is hoisted. The utility model discloses can the not equidimension rotor of adaptation, connect different lifting eyes through changing driving rings, make rings be in approximately behind hoisting accessory and the rotor is connected the focus of whole device directly over, make the rotor can keep in approximate horizontally position. And the lifting point is arranged above the rotor, so that the field of the rotor tool is reduced. The welding has the operation handle on the stub, conveniently controls the rotor and lifts by crane the direction in the installation with, rotation when preventing that the rotor from lifting to can finely tune the rotor after lifting, make it keep the level in the installation as far as possible, shorten the man-hour of this step, accelerated the progress of complete machine production.
