Multiple second idler wheels 33 are set in slide plate 12, the quality of traction electric machine stator 7 is larger, multiple in order to make 12 uniform force of slide plate
The bottom side for being distributed in slide plate 12 of second idler wheel 33 perfectly even.
Complete overturning after, need to hang out traction electric machine stator 7, can traction electric machine stator 7 upside end face with
It is screwed into the hanging ring equipped with threaded rod in the fixation wire hole of end cap, traction electric machine stator can be sling by the hanging ring, preferably be existed
The upper end of strut 11 offers external thread structure, and the lifting lug 34 for being equipped with screw hole using one is threaded in the upper end of strut 11.
After slinging traction electric machine stator 7 by lifting lug 34, traction electric machine stator 7 can be stabilizer blade with strut 11, be stably placed at
In working region, stability when slinging and place in order to ensure traction electric machine stator 7, the quantity in hole 10 is preferably 4 or 6,
4 or 6 struts thus can be used.
The principle of the present invention is illustrated in conjunction with Fig. 2 to 9, and the piston rod for first controlling first hydraulic cylinder 3 stretches out, and makes the first seat board 6
It is maintained at horizontal position, then traction electric machine stator 7 is hung in 24 upside of turntable, is driven by adjusting the second driving part 26
Turntable 24 rotates, and passes through the left-right position of 31 regulating orifice plate 9 of second hydraulic cylinder, makes on strut 11 and traction electric machine stator 7
Then cooling air holes 71 makes slide plate 12 move right, keeps 11 entrance of strut right therewith to just by the rotation of the first driving part 15
In the cooling air holes 71 answered, and after the right end face of traction electric machine stator 7 is abutted with limiting section 111, lifting lug 34 is screwed in branch
The outer end of bar 11, the piston rod for then controlling first hydraulic cylinder 3 are shunk, the first seat board 6 rotation to vertical position.In this way,
Traction electric machine stator 7 is overturn by horizontality as vertical state, then slings traction electric machine stator 7, strut 11 is with traction electricity
Machine stator 7 is extracted from hole 10, and strut 11 can become the footing of traction electric machine stator 7 at this time, can be directly placed on ground
Related cleaning, drying and dipping lacquer work is carried out to hang traction electric machine stator 7 on orifice plate 9 after completing above-mentioned work, and
It is inserted into the lower end of strut 11 in hole 10, and the side of slide plate 12 is arranged in the bottom of traction electric machine stator 7, then controls the again
The piston rod of one hydraulic cylinder 3 stretches out, and the first seat board 6 is made to turn to horizontal position, can be by traction electric machine stator 7 by vertical state
Overturning is horizontality, and control the first driving part 15 reversion can be such that slide plate 12 is moved to the left, then can determine traction electric machine
Sub 7 levels are sling.
In conclusion the present invention overturns the rotation of the first seat board by traction electric machine stator by hydraulic cylinder extension, lead to
The control turntable rotation of the second driving part is crossed, by the left-right position of second hydraulic cylinder regulating orifice plate, strut and cooling wind can be made
Hole drives slide plate is mobile to be inserted into strut in cooling air holes to just, by the first driving part, easy to operate, branch when overturning
Bar limits traction electric machine stator, will not cause to damage to stator winding, and overturning back stay, which becomes stabilizer blade, directly to be put
It sets in working region, convenient for the operation such as the cleaning, drying and dipping lacquer in later period.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
