Embodiment
Embodiment in is by reference to the accompanying drawings further described by the utility model below:
As shown in Figure 1 and 2, the utility model mainly comprises active pull rod 3, and active pull rod 3 connects movable sleeve 4, intermediate active cover 7 and lower fixed cover 13 from top to bottom successively.Active pull rod 3 end is connected by screw taper sheath 16, and taper sheath 16 lower end connects bumper bar 18.
As shown in Figure 2, movable sleeve 4 is provided with loose slot 19, the stop screw 20 be connected on active pull rod 3 is provided with in loose slot 19, by loose slot 19, movable sleeve 4 can be moved up and down and can radial rotating, under stop screw 20 limits, the relative motion between movable sleeve 4 and active pull rod 3 can only be controlled by the scope of activities of stop screw 20 at loose slot 19.
Intermediate active is overlapped 7 outer surfaces and is connected outer movable whorl pipe 6, movable whorl pipe 6 connects top nut 8 and lower nut 12 outside, is provided with multiple along the circumferential direction equally distributed link assembly between top nut 8 and lower nut 12.Each link assembly comprises connecting rod 9, lower link 11 and roller 10, upper connecting rod 9 upper end thereof top nut 8, the hinged roller 10 in upper connecting rod 9 lower end, lower link 11 upper end thereof roller 10, the hinged lower nut 12 in lower link 11 lower end.
Described outer movable whorl pipe 6 connects dog screw 5, and dog screw 5 is under tight condition, and outer movable whorl pipe 6 and intermediate active are overlapped 7 locked; Dog screw 5 in the loosened condition, outer movable whorl pipe 6 and intermediate active cover 7 between interaction.
Lower fixed cover 13 lower end welding claw seat 14, hinged multiple along the circumferential direction equally distributed claw 15 in claw seat 14, each claw 15 be connected an extension spring 17 between taper sheath 16.
Described claw 15 surface is 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 end connects adapter sleeve 2, and adapter sleeve 2 upper end connects suspension ring 1.
Operation principle of the present utility model 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 pull out suspension ring 1 with hand, make stop screw 20 arrive the most upper limit position of loose slot 19, then rotate movable sleeve with hand, turn motionless put in place (turning over 90 degree) until encounter.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 surface, and reach maximum.Now stator winding part can cover and be supported and (be stained with wear-resisting soft rubber layer with seccotine above claw 15 to contact with stator core coil place by claw 15 completely; protection stator core coil insulation paint is not destroyed); use the whole outer movable whorl pipe 6 of hand accurate adjustment again, make roller 10 encounter stator inner wall contact.Preprepared insurance machine frame is positioned over appropriate location on concrete Horizon, then uses lifting appliance (driving or balance crane etc.) to be sling by suspension ring 1, until axis stator and horizontal plane.
The stator core of lifting is hung in electric machine stand endoporus top, unclamp dog screw 5, rotate outer movable whorl pipe 6 position, roller 10 is separated with stator core endoporus, and has enough distances.Then rotate movable sleeve 4 to reach in 90 degree (along fluting directions), to pressing down active pull rod 3, taper sheath 16 conical surface being moved down, due to the effect of extension spring 17, claw 15 inwardly being shunk along taper sheath 16 conical surface, and reaches minimum.Now, unique stator drop hanger is taken out from stator core.
Owing to unloading in the middle of process in whole installation, only need rotate movable sleeve and outer movable whorl pipe with hand, without the need to using too much instrument, so operation is also very simple, therefore the operating time shortens, and improves productivity ratio.
