Abstract
The utility model relates to a lifting frame for hanging a magnetic pole of a large hydrogenerator rotor. The lifting frame is characterized by comprising two cross beams which are arranged in parallel; supporting beams are uniformly distributed and fixedly arranged between the bottoms of the two cross beams; a vertical plate is fixedly arranged on the supporting beam at one end part; the outer side of the vertical plate is fixedly provided with a lifting plate which is provided with a lifting hole through which a lifting rope penetrates; and the outer sides of the two cross beams are symmetrically and fixedly provided with the lifting plates. In lifting, a magnetic pole is placed on the lifting frame, four lifting hooks at the outer sides of the cross beams hook damping rings of the magnetic pole respectively, then one end of the lifting rope penetrates through the lifting hole of the lifting plate, the other end of the lifting rope is hung on the lifting hook of a crown block, and the magnetic pole can be vertically hung on a rotor bracket. Therefore, the structure has the advantages that the operation is simple, fast, safe, time-saving and labor-saving, effective and the like, and the coil of the magnetic pole can not be damaged.
Description
Technical field
The utility model belongs to the large-sized water turbine generator technical field, particularly relates to a kind of large-sized water turbine generator rotor magnetic pole and mounts upending frame.
Background technology
Rotor is important cover of large-sized water turbine generator, it is magnetic pole is mounted on the rotor field spider and is combined into the rotor portions cover, magnetic pole is a strength member, it is dimeric: pole core and pole coil, pole core is to be through with screw rod by some sheet metals to become an integral body together, pole coil is to turn to a multiturn by copper belt to be the Long Circle pole coil, and at the interlayer cushioning insulating paper of every circle, by heating pole coil and insulating paper are pressed into an integral body, magnetic pole is formed in the outside that then pole coil is enclosed within pole core.
Because the magnetic pole weight of large-sized water turbine generator arrives several thousand kilograms at the hundreds of kilogram, manually magnetic pole can not be mounted on the rotor field spider, be mounted on the rotor field spider after must magnetic pole being mentioned by overhead traveling crane and lifting tool, at present, when mounting magnetic pole, there is not special-purpose magnetic pole to mount instrument, the staff directly is enclosed within an end lifting rope on the pole body of pole coil, the other end carries out magnetic pole with the overhead traveling crane hook and mounts, the easy like this compressive strain of reining in that causes pole coil, and cause pole coil turn-to-turn cracking, thus cause the defective needs of magnetic pole to reprocess, and take a lot of work, time-consuming, efficient is low.
Summary of the invention
The utility model for solve the technical problem that exists in the known technology provide a kind of simple in structure, easy to install, simple to operate, fast, safely, save time, large-sized water turbine generator rotor magnetic pole laborsaving, that efficient is high mounts upending frame.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of large-sized water turbine generator rotor magnetic pole mounts upending frame, it is characterized in that: this upending frame comprises the crossbeam of two parallel placements, the uniform brace summer that is fixed with between the bottom of two crossbeams, at one end be fixed with riser on the brace summer of portion, the outside of riser has been fixed with boatswain chair, play boatswain chair and be provided with the hole for hoist that installs lifting rope, the outside symmetry of described two crossbeams has been fixed with boatswain chair.
The utility model can also adopt following technical measures:
Described crossbeam is a channel-section steel, the staggered relatively and several brace summers that are parallel to each other of the groove surface of channel-section steel, and brace summer is welded in the groove of channel-section steel.
Described being fixed between riser on the end portion supports beam and the brace summer is fixed with the reinforcement gusset.
The described centre position that boatswain chair is positioned at riser of rising that is packed on the riser.
Describedly on two crossbeams of the offside that installs riser, all also be fixed with supporting bracket.
The lower surface of described supporting bracket is a fillet.
The described boatswain chair that rises that is packed on the crossbeam outside is the L type.
Advantage and the good effect that the utlity model has are: because the utility model adopts said structure, when lifting, magnetic pole is placed on the upending frame, four hooks in the crossbeam outside are hooked the damping ring of magnetic pole respectively, then an end of lifting rope has been penetrated the hole for hoist of boatswain chair, the other end of lifting rope hangs on the hook of overhead traveling crane, just magnetic pole vertically can be erected to mount on the rotor field spider.Therefore said structure have simple to operate, fast, safely, save time, laborsaving, efficient advantages of higher, and can not damage by the pole coil volume.
