Detailed description of the invention
The embodiment combined in accompanying drawing is further described by the present invention below:
As shown in Figure 1 and 2, the invention mainly comprises active pull rod 3, active pull rod 3 is sequentially connected with movable sleeve 4, intermediate active set 7 and lower fixed cover 13 from top to bottom.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, loose slot 19 is 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 limits, the relative motion between movable sleeve 4 and active pull rod 1 can only be controlled in the range of activity of loose slot 19 by stop screw 20.
Intermediate active is overlapped 7 outer surfaces and is connected outer movable whorl pipe 6, connects top nut 8 and lower nut 12 outside, be provided with multiple link assembly being distributed uniformly and circumferentially between top nut 8 and lower nut 12 on movable whorl pipe 6.Each link assembly includes connecting rod 9, lower link 11 and roller 10, upper connecting rod 9 upper end thereof top nut 8, the hinged roller in upper connecting rod 9 lower end 10, lower link 11 upper end thereof roller 10, the hinged lower nut in lower link 11 lower end 12.
Connecting location screw 5 on described outer movable whorl pipe 6, location screw 5 is under tight condition, and it is locked that outer movable whorl pipe 6 and intermediate active overlap 7；In the loosened condition, outer movable whorl pipe 6 and intermediate active overlap interaction between 7 to location screw 5.
Lower fixed cover 13 lower end welding claw seat 14, hinged multiple claws 15 being distributed uniformly and circumferentially in claw seat 14, it is connected a stretching spring 17 between each claw 15 and taper sheath 16.
Described claw 15 surface is provided with wearing layer, and wearing layer uses soft rubber material to make.Wearing layer contacts at stator core coil, 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.
The operation principle of the present invention is: during work, first the location screw 5 on intermediate active set 7 is unclamped, the position of the outer movable whorl pipe 6 of the concrete length adjustment according to stator core so that when the interior hole site of link assembly action rear roller 10 and stator is in the place from stator core suitable for reading 1/4th.Then pulling out suspension ring 1 with hands so that stop screw 20 arrives loose slot 19 upper limit position, then rotates movable sleeve with hands, turning motionless put in place (turning over 90 degree) until encountering.Now, due to stretching the spring 17 and effect of taper sheath 16, make claw 15 stretch out to extending out along taper sheath 16 conical surface, and reach maximum.Now claw 15 is fully able to stator winding part covered and supported that (the above seccotine of claw 15 is stained with wear-resisting soft rubber layer and contacts at stator core coil; protection stator core coil insulation paint is not destroyed); again with the whole outer movable whorl pipe 6 of hands accurate adjustment, roller 10 is made to encounter stator inner wall contact.Preprepared insurance machine frame is positioned over appropriate location on concrete Horizon, then with lifting appliance (driving or balance crane etc.), suspension ring 1 is sling, until axis stator and horizontal plane.
The stator core of lifting is hung in electric machine stand endoporus top, unclamps location screw 5, rotate outer movable whorl pipe 6 position, make roller 10 separate with stator core endoporus, and have enough distances.Then rotate movable sleeve 4 and reach 90 degree (along fluting directions), be pressed downward against active pull rod 3, make taper sheath 16 conical surface move down, owing to stretching the effect of spring 17, make claw 15 along taper sheath 16 conical surface to contract, and minimize.Now, unique stator drop hanger is taken out from stator core.
Owing to unloading in the middle of process in whole installation, only movable sleeve and outer movable whorl pipe need to be rotated with hands, it is not necessary to use too much instrument, so, operate the most extremely simple, therefore the operating time shortens, and improves productivity ratio.
