Abstract
The utility model discloses a special lifting tool for an adjustable stator, which comprises a lifting cylinder, a plurality of adjusting combinations and lifting rings, wherein the plurality of adjusting combinations are vertically fixed on the outer circle of the lifting cylinder at intervals, and the lifting rings are vertically fixed at the top of the lifting cylinder; each adjusting combination comprises a supporting piece, an adjusting bracket and an adjusting bolt, the inner side of the supporting piece is fixedly connected with the outer circle of the lifting cylinder, the inner end of the adjusting bracket is vertically fixed on the outer side of the supporting piece, and the adjusting bolt is screwed on the outer end of the adjusting bracket. The utility model discloses the structure is small and exquisite, easy operation. When lifting small inner diameter stator, will the utility model discloses fill in the stator hole, adjust several adjusting bolt's length, several adjusting bolt withstands the stator hole respectively, after reaching sufficient pretightning force, the weight that frictional force is greater than stator and whole instrument can lift by crane the stator, low in labor strength, and work efficiency is high. Because the length of the adjusting bolt is adjustable, the adjustable fixed diameter of the range of the stator of the range of the lifting device can be used for hoisting stator of the internal diameter within a range.
Description
Technical Field
The utility model relates to a lifting tool when assembly of generator stator income shell, especially a lifting tool that can lift by crane multiple little internal diameter stator belongs to generator assembling tool technical field.
Background
The stator is one of the key parts of the generator, and the quality of the assembly quality directly influences the overall performance and the service life of the generator. According to the type of the generator, a stator of the generator must be pressed into a designated position in a base from a driving end or a non-driving end of the base, the position is a position where a rotor can be correctly aligned with the stator after being rotationally matched, and two ends of a rotor journal and a sliding bearing bush form a correct gap, and is also a position of a magnetic center line of a stator and a rotor. Because the stator volume is big, and weight is heavy, is covered with the coil on one's body, but the clamping part is few, easily impaired and cause and scrap, therefore the most difficult link in the pressure equipment process is the problem of lifting by crane of stator. At present, an internal expansion type hoisting tool is generally adopted to hoist a stator, the stator is plugged into an inner hole of the stator during hoisting, then the stator is hoisted and pressed into a base, but the tool is complex in structure and complex in operation, and is only suitable for the stator with a larger inner diameter due to the fact that the tool is too large in size and does not have an adjusting function, and cannot be used for hoisting the stator with a smaller inner diameter, and the application range is smaller.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a simple structure, convenient operation, can be used to lift by crane the special lifting means of adjustable stator of multiple little internal diameter stator in the certain limit.
The utility model discloses a following technical scheme realizes:
a lifting tool special for an adjustable stator comprises a lifting cylinder, a plurality of adjusting combinations and lifting rings, wherein the adjusting combinations are vertically fixed on the outer circle of the lifting cylinder at intervals, and the lifting rings are vertically fixed at the top of the lifting cylinder; each adjusting combination comprises a supporting piece, an adjusting bracket and an adjusting bolt, wherein the inner side of the supporting piece is fixedly connected with the outer circle of the lifting cylinder, the inner end of the adjusting bracket is vertically fixed on the outer side of the supporting piece, and the adjusting bolt is screwed on the outer end of the adjusting bracket.
The object of the invention is further achieved by the following technical measures.
The lifting cylinder comprises a cylinder body, a top plate and a bottom plate, wherein the top plate and the bottom plate are respectively fixed at the top and the bottom of the cylinder body.
In the lifting tool special for the adjustable stator, the supporting member comprises two supporting plates, and the two supporting plates are fixed on the outer circle of the cylinder body side by side.
In the lifting tool special for the adjustable stator, the adjusting bracket is in a cylindrical shape with a flange.
The utility model discloses the structure is small and exquisite, and is with low costs, easy operation, convenient to carry. When lifting small inner diameter stator, will the utility model discloses fill in the stator hole, adjust several adjusting bolt's length makes whole instrument radial expansion back, and several adjusting bolt withstands the stator hole respectively, and after reaching sufficient pretightning force, the weight that frictional force is greater than stator and whole instrument can lift by crane the stator, low in labor strength, and work efficiency is high. Because the length of the adjusting bolt is adjustable, the adjustable fixed diameter of the range of the stator of the range of the lifting device can be used for hoisting stator of the internal diameter within a range.
The advantages and features of the invention will be illustrated and explained by the following non-restrictive description of preferred embodiments, which are given by way of example only with reference to the accompanying drawings.

fig. 2 is a schematic structural view of the stator hoisting device of the present invention.
Detailed Description
The present invention will be further explained with reference to the drawings and examples.
As shown in figure 1, the utility model discloses a lifting cylinder 1, three regulation combination 2 and lifting ring 3, lifting cylinder 1 includes barrel 11, roof 12 and bottom plate 13, and roof 12 and bottom plate 13 welded fastening are respectively in the top and the bottom of barrel 11, and three regulation combination 2 vertical separation is fixed on the excircle of barrel 11, and lifting ring 3 closes perpendicularly soon to be fixed on lifting cylinder 1's roof 12. Every regulation combination 2 includes support piece 21, regulation support 22 and adjusting bolt 23, and support piece 21 includes two backup pads 211, and two backup pads 211 are welded fastening side by side on the excircle of barrel 11, and the perpendicular welded fastening of regulation support 22 inner is on two backup pads 211 outsides, and adjusting bolt 23 closes soon on the outer end of adjusting support 22, and adjusting support 22 is the cylinder of flanged.
As shown in fig. 2, when hoisting the stator 4, firstly, respectively padding the rubber pads 5 at the corresponding positions of the inner hole of the stator 4, simultaneously, rotating the three adjusting bolts 23 of the hoisting tool to the shortest, then inserting the hoisting ring 3 of the hoisting tool into the inner hole of the stator 4, and rotating the adjusting bolts 23 outwards, so that the adjusting bolts 23 prop against the inner hole of the stator 4, thereby hoisting the stator 4.
In addition to the above embodiments, the present invention can also have other embodiments, and all technical solutions formed by equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
