Embodiment
The present invention is below further described in connection with the embodiment in accompanying drawing:
As shown in Figure 1 and 2, the present invention mainly comprises active pull rod 3, connects successively from top to bottom movable sleeve 4, intermediate active cover 7 and lower fixed cover 13 on active pull rod 3.Active pull rod 3 ends are connected by screw taper sheath 16, and taper sheath 16 lower ends connect bumper bar 18.
As shown in Figure 2, movable sleeve 4 is provided with loose slot 19, in loose slot 19, be provided with the stop screw 20 being connected on active pull rod 1, by loose slot 19, movable sleeve 4 can be moved up and down and can radial rotating, under stop screw 20 restrictions, the relative motion between movable sleeve 4 and active pull rod 1 can only be controlled in the scope of activities of loose slot 19 by stop screw 20.
Intermediate active is overlapped 7 outer surfaces and is connected outer movable whorl pipe 6, connects outside top nut 8 and lower nut 12 on movable whorl pipe 6, is provided with a plurality of along the circumferential direction equally distributed link assemblies between top nut 8 and lower nut 12.Each link assembly comprises connecting rod 9, lower link 11 and roller 10, the upper connecting rod 9 hinged top nuts 8 in upper end, the upper connecting rod 9 hinged rollers 10 in lower end, the lower link 11 hinged rollers 10 in upper end, the lower link 11 hinged lower nuts 12 in lower end.
On described outer movable whorl pipe 6, connect dog screw 5, dog screw 5 is under tight condition, and it is 7 locked that outer movable whorl pipe 6 and intermediate active are overlapped; Dog screw 5 under releasing orientation, interaction between outer movable whorl pipe 6 and intermediate active cover 7.
Lower fixed cover 13 lower ends welding claw seats 14, the interior hinged a plurality of along the circumferential direction equally distributed claws 15 of claw seat 14, are connected an extension spring 17 between each claw 15 and taper sheath 16.
Described claw 15 surfaces are provided with wearing layer, and wearing layer adopts soft rubber material to make.Wearing layer contacts with stator core coil place, and protection stator core coil insulation paint is not destroyed.
Described active pull rod 3 upper ends connect adapter sleeve 2, and adapter sleeve 2 upper ends connect suspension ring 1.
Operation principle of the present invention is: during work, first the dog screw 5 on intermediate active cover 7 is unclamped, according to the position of the outer movable whorl pipe 6 of the concrete length adjustment of stator core, make the interior hole site of working as link assembly action rear roller 10 and stator in the place from stator core suitable for reading 1/4th.Then with hand, pull out suspension ring 1, make stop screw 20 arrive the upper limit of loose slot 19 position, then rotate movable sleeve with hand, until encounter, turn motionless and put in place (turning over 90 degree).Now, due to the effect of extension spring 17 and taper sheath 16, make claw 15 stretch out to extending out along taper sheath 16 conical surfaces, and reach maximum.Now claw 15 can partly cover stator winding and be supported that (claw 15 is stained with wear-resisting soft rubber layer with seccotine above and contacts with stator core coil place completely; protection stator core coil insulation paint is not destroyed); use again the whole outer movable whorl pipe 6 of hand accurate adjustment, make roller 10 encounter stator inner wall contact.Preprepared insurance machine frame is positioned over to appropriate location on concrete Horizon, then uses lifting appliance (driving or balance crane etc.) that suspension ring 1 are sling, until axis stator is vertical with horizontal plane.
The stator core of lifting is hung in to electric machine stand endoporus top, unclamp dog screw 5, rotate outer movable whorl pipe 6 positions, make roller 10 separated with stator core endoporus, and have enough distances.Then rotate movable sleeve 4 and reach 90 degree (along fluting direction), to pressing down active pull rod 3, taper sheath 16 conical surfaces are moved down, due to the effect of extension spring 17, claw 15 is inwardly shunk along taper sheath 16 conical surfaces, and reach minimum.Now, unique stator drop hanger is taken out from stator core.
In the middle of unloading process in whole installation, only need rotate movable sleeve and outer movable whorl pipe with hand, without using too much instrument, so, operate also very simple, therefore operating time shortening has improved productivity ratio.
