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, and it is dimeric: pole core and pole coil, pole core are 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, pole coil and insulating paper are pressed into an integral body through heating at the interlayer cushioning insulating paper of every circle, then pole coil is enclosed within the outside composition magnetic pole of pole core.
Because to several thousand kilograms, manual work can not be mounted on magnetic pole on the rotor field spider magnetic pole weight of large-sized water turbine generator at the hundreds of kilogram, 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; Thereby 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, is uniformly distributed with between the bottom of two crossbeams and is fixed with brace summer; At one end be fixed with riser on the brace summer of portion; Be fixed between riser and the brace summer on the end portion, supports beam and be fixed with the reinforcement gusset, on two crossbeams of the offside that installs riser, all be fixed with supporting bracket, the outside of riser has been fixed with boatswain chair; Be packed in the centre position that boatswain chair is positioned at riser of rising on the riser; Play boatswain chair and be provided with the hole for hoist that installs lifting rope, the outside symmetry of said two crossbeams has been fixed with boatswain chair, and the boatswain chair that rises that is packed on the crossbeam outside is the L type.
The utility model can also adopt following technical measures:
Described crossbeam is a channel-section steel, and the groove surface of channel-section steel is placed relatively and the several brace summers that are parallel to each other are arranged, and brace summer is welded in the groove of channel-section steel.
The lower surface of said supporting bracket is a fillet.
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 can magnetic pole vertically 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.

Embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1 to Fig. 3,
A kind of large-sized water turbine generator rotor magnetic pole mounts upending frame, comprises the crossbeam (1,2) of two parallel placements, is uniformly distributed with between the bottom of two crossbeams and is fixed with brace summer 3; At one end be fixed with riser 4 on the brace summer 3 of portion; The outside of riser has been fixed with boatswain chair 5, according to force analysis, when a boatswain chair is packed in the centre position on the riser; The bearing capacity that plays boatswain chair is bigger, and whole boatswain chair is stressed comparatively even.Play boatswain chair 5 and be provided with the hole for hoist 5-1 that installs lifting rope, the outside symmetry of said two crossbeams (1,2) has been fixed with boatswain chair 6, and the boatswain chair system of rising is the L type.
For ease of processing and manufacturing; Crossbeam in said structure is chosen as existing channel-section steel; And several brace summers of placing relatively and be parallel to each other at the groove surface of channel-section steel, brace summer is welded in the groove of channel-section steel, and this channel-section steel also is convenient to processing when welding; The lower surface of groove also has certain supporting role simultaneously, guarantees the intensity of whole upending frame.
In order to strengthen the intensity between riser 4 and the brace summer 3, be fixed on to be fixed with between riser 4 and the brace summer 3 on the end portion, supports beam 3 and strengthen gusset 7.
Saidly on two crossbeams of the offside that installs riser, all also be fixed with supporting bracket 8, this supporting bracket 8 prevents mainly in the lifting process that the lifting rope swing is excessive and magnetic pole is caused collide with, play steady, stressed uniform effect that the lower surface of said supporting bracket is a fillet.
See also Fig. 4 to Fig. 5, user mode is placed into magnetic pole 9 on the upending frame; Four hooks in the crossbeam outside are hooked the damping ring 10 of magnetic pole respectively; Then an end of lifting rope 11 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 can magnetic pole vertically 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.
