Abstract
The invention provides a stator heat-sleeving supporting tool which is composed of a base board (1), a supporting sleeve (2), pressing boards (3), pull rods (4) and alignment blocks (5). The base board (1) is connected with the supporting sleeve (2) through screws. The base board (1) is provided with threaded holes which are machined for fixing the pull rods (4). The pressing boards and the alignment blocks (5) are connected with a stator base (6) through bolts. The upper end of the supporting sleeve (2) is provided with an annular trough for fixing a supporting ring (7). A stator core (8) is placed on the supporting ring (7). The stator heat sleeve supporting tool is advantageous in that threaded connection is utilized among the parts, thereby realizing convenient detachment; after the stator base is heated, heat-sleeving on the stator core through direct alignment can be performed, thereby saving heat-sleeving time; and in a cooling process, the pressing boards and the base board are tensioned through the pull rods, thereby ensuring the stator base and the stator core in a compressed state always.
Description
Technical field：The present invention relates to a kind of stator heating jacket stake tool.
Background technology：Traditional stator heating jacket is usually to fix out frame after heating, and stator core of slinging is toward stator
Cover in support, this requires that the instrument for lifting by crane stator core is arranged on end or inner side, otherwise can interfere with out frame,
And End zone of stator core typically has coil to be inconvenient to arrange suspender, inner side may have ceramic voussoir to be inconvenient to use expander, can only
Stator core for different structure designs different lifting tools, bothers very much, it is therefore desirable to a kind of new-type hot jacket instrument
Stator heating jacket under to meet different situations.
The content of the invention：It is an object of the invention to provide a kind of stator heating jacket stake tool, saves hot jacket time, and can
To be lifted by crane from stator core outside.The present invention is adopted the following technical scheme that：A kind of stator heating jacket stake tool, the instrument
It is made up of base plate (1), support tube (2), pressing plate (3), pull bar (4) and alignment block (5), base plate (1) is with support tube (2) by screw
Connection；Thread mill drilling is used for steady brace (4) on base plate (1)；Pressing plate (3) is bolted in stator with alignment block (5)
On support (6)；Support tube (2) upper end is installed annular groove and fixes support ring (7), and stator core (8) is placed in support ring (7).
Along the uniform multiple pull bars (4) of base plate (1) surrounding, along the uniform multiple pressing plates (3) of out frame (6) surrounding, pull bar (4)
Through the hole on pressing plate (3) and using nut tight.
Groove is carried on support tube (2) and base plate (1), groove aligns with the key on out frame (6).
The operation principle of the present invention：Base plate (1) and support tube (2) are connected by screw, and by support ring (7) support is played
The effect of stator core (8), pressing plate (3) and alignment block (5) are bolted on out frame (6), same to out frame (6)
Heat together, when hot jacket is to final position, the pull bar (4) allowed on base plate (1) through the pressing plate (3) on out frame (6) and
With nut screwing clamping, it is ensured that stator core (8) and out frame (6) are constantly in impaction state in cooling procedure, base plate (1),
Groove is processed on support cylinder (2) and alignment block (5), groove is respectively aligned to the key of the keyway of stator core (8) and out frame (6),
As long as ensureing that groove alignment can just allow stator core (8) and out frame (6) to cover just during hot jacket.
Specific work process of the present invention can refer to following example：Before hot jacket first by support tube (2) by screw be arranged on bottom
On plate (1), both groove alignment are ensured after installing, by pull bar (4) on base plate (1), then by support ring (7)
It is placed in successively on support tube (2) with stator core (8), ensures during placement on keyway alignment support cylinder (2) of stator core (8)
Groove, with bolt by pressing plate (3) and alignment block (5) on out frame (6), during installation ensure alignment block (5) quarter
Line aligns with the key of out frame (6), heating out frame (6), out frame (6) is lifted by crane after having heated and by its hot jacket fixed
On sub- iron core (8), ensure that the groove on alignment block (6) aligns with the groove on support tube (2) or base plate (1) during hot jacket, stator
Support (6) will allow pull bar (4) through pressing plate (3) when reaching specified location, then be tightened on pull bar (4) and pressing plate (3) with nut,
Until out frame (6) is cooled down completely, after hot jacket terminates, instrument is removed, break storage.
The key of device of the present invention is that support tube (2) holds up stator core (8) certain altitude, it is ensured that when hot jacket is completed
Out frame (6) has certain distance with base plate (1)；The groove of base plate (1), groove, the stator core of support tube (2) during hot jacket
(8) key of keyway, the groove of alignment block (5) and out frame (6) aligns all the time, it is ensured that out frame (6) and stator core (8)
Set is just；When out frame (6) reaches specified location, straining at bar (4) and pressing plate (3), it is ensured that out frame (6) in cooling procedure
Impaction state is in all the time with stator core (8).
It is an advantage of the current invention that：Can be lifted from stator core outside, without using special hanger；Stator can be made
Directly hot jacket is time-consuming in stator core for seat, reduces the cooling of out frame, improves hot jacket success rate；In cooling procedure,
Out frame and stator core is allowed to remain impaction state, it is to avoid the generation in hot jacket gap.
Description of the drawings
Schematic diagram when Fig. 1 is out frame arrival final position.
Fig. 2 is the overall structure diagram of the present invention.
Specific embodiment
A kind of stator heating jacket stake tool as shown in Figure 1, the instrument is by base plate 1, support tube 2, pressing plate 3, the and of pull bar 4
Alignment block 5 is constituted, and base plate 1 is connected by screw with support tube 2；Thread mill drilling is used for steady brace 4 on base plate 1；Pressing plate 3 with
