Description
Technical field
The utility model relates to electrical generator fields, is specially a kind of unit for megawatt double-fed wind generators group generator centering special purpose device.
Background technology
MW class wind turbine group, in the time carrying out the operation of generator centering, generally adopts jack by generator jack-up at present, then carries out the operation of generator centering with instruments such as crow bars.This operating type accuracy is low, and fault rate is high, and is not easy to operation in small space.
Utility model content
The technical problem that the utility model solves is to provide one can coordinate jack to complete fast the work of generator centering, and unit for megawatt double-fed wind generators group generator centering special purpose device easy to carry, to solve the problem proposing in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of unit for megawatt double-fed wind generators group generator centering special purpose device, comprises base plate, screw rod, nut and supporting plate; Described base plate is provided with the gusset that is threaded hole; Described nut apparatus is in one end of the screw rod in gusset outside, in the screwed hole of the other end device of screw rod on gusset; Both sides corresponding with gusset upper screwed hole on described supporting plate are equipped with stopper, and supporting plate is placed on base plate, and liner plate is equipped with in supporting plate bottom.
Further, described gusset quantity is two, is symmetricly set on the two ends of base plate.
Further, the quantity of described screw rod is two.
Beneficial effect
The utility model can complete the generator centering operation of double-fed wind power generator group in limited cabin space, and easy to operate, fast to medium velocity, precision is high, meanwhile, also there is dismounting and assemble again, simple in structure, be easy to carry, the advantage such as cost of manufacture is low, economical and practical.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Detailed description of the invention
In order to make of the present utility modelly to realize technological means, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of unit for megawatt double-fed wind generators group generator centering special purpose device, comprises base plate 1, screw rod 2, nut 3 and supporting plate 4; Described base plate 1 is provided with the gusset 5 that is threaded hole; Described nut 3 installs in one end of the screw rod in gusset 5 outsides, in the screwed hole of the other end device of screw rod 2 on gusset 5; On described supporting plate 4, the both sides corresponding with gusset upper screwed hole are equipped with stopper 4-1, and supporting plate 4 is placed on base plate 1, and liner plate 6 is equipped with in supporting plate 4 bottoms, and wherein, described gusset 5 quantity are two, are symmetricly set on the two ends of base plate; The quantity of described screw rod 2 is two.
When work, first, the bottom of hydraulic jack is placed on supporting plate 4, the top of hydraulic jack is just under motor front portion; Then, by generator jack-up, generator is separated with jack with resiliency supported; According to adjusting requirement, rotate the bolt 2 on base plate 1 in this device with ratchet spanner, one end of bolt 2 props up the stopper 4-1 on supporting plate, and then promotion supporting plate 4 moves, supporting plate 4 moves and drives the generator of jack and jack-up to move, and then the adjustment (generator rear end used same method) of realization to generator left-right deviation, then, realize the adjustment to lower deviation on generator by the height of adjusting resiliency supported, jack pressure release after adjustment completes, is finally adjusted in the scope of error permission.
More than show and described general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.Claimed scope of the present utility model is defined by appending claims and equivalent thereof.
