One end be rotatably connected to support rod 17, have the differential reel 14 being mounted in third shaft 18 between support rod 17 and shell 5,
The differential reel 14 is made of the parent roll portion and rouleau canister portion of coaxial line and the diameter in parent roll portion is greater than rouleau canister portion
Diameter is connected with wirerope 15 on 14 outer wall of differential reel, and one end of wirerope 15 winds its other end around parent roll portion
Around the winding of rouleau canister portion and side that the direction that winds in parent roll portion of wirerope 15 and wirerope 15 are wound in rouleau canister portion
To on the contrary, the lower section of the differential reel 14 is equipped with wire rope hole 19 on base 1, the middle part of the wirerope 15 is worn to folding down
Cross the wire rope hole 19 of 14 lower section of differential reel.
14 outer wall of differential reel is equipped with the spiral steel wire rope groove 16 cooperated with wirerope 15, and wirerope 15 twines
It is wound in steel wire rope groove 16, makes wirerope 15 is orderly to be wrapped on differential roller.
Canoe of the wirerope 15 on differential reel 14 is illustrated referring to Fig. 2, one end of wirerope 15 is fixed
In then steel wire rope groove 16 that the right side of the rouleau canister portion of differential reel 14 is successively wrapped in rouleau canister portion to the left, wirerope 15
The other end be fixed on differential reel 14 parent roll portion left side then be successively wrapped in the steel wire rope groove in parent roll portion to the right
In 16.
The first driving device and the second driving device is made of driving motor 2 and retarder 3, driving motor 2
Power, transmitting of the retarder 3 for matching and the torque of revolving speed are provided for headstock gear.
A tapered roller thrust bearing 4, and first rotating shaft are equipped between first rotating shaft 9, third shaft 18 and shell 5
9 and third shaft 18 on tapered roller thrust bearing 4 be symmetrical arranged, set between the second shaft 8 and shell 5 there are two thrust circle
Taper roller bearing 4 and tapered roller thrust bearing 4 are symmetrical arranged.Tapered roller thrust bearing 4 is used to support first rotating shaft 9, the
Two shafts 8, third shaft 18 make first rotating shaft 9, and the second shaft 8, third shaft 18 can be rotated smoothly, this extrapolability circle
Taper roller bearing 4 can bear very heavy axial load, and impact loading is insensitive, and rigidity is good, ensures that opening and closing in this way
Machine maintainability.
It is illustrated in conjunction with working principle of the Fig. 2 to differential reel 14, when third shaft 18 rotates a circle around own axes
While, differential reel 14 also rotates a circle around the axis of itself, since the drum diameter in 14 left side of differential reel is less than right side
Drum diameter, be wrapped in differential volume along spiral steel wire rope groove 16 so being wrapped in the wirerope 15 of 14 two sides of differential reel
It is perhaps unclamped from differential reel 14 on cylinder 14 and the length of the winding of side that diameter is big or the wirerope 15 unclamped is always greater than
The small side of diameter, therefore the length for the wirerope 15 for winding and unclamping on differential reel 14 is formed a length difference,
Thus make to be moved up and down by wirerope 15 by the gate that lifting lug connects, to realize the control to gate lifting.
It is illustrated in conjunction with the remote principle of transmission of the Fig. 1 to headstock gear, when the electricity of first driving device and the second driving device
When machine 2 is rotated clockwise with identical revolving speed, one side first rotating shaft 9 is rotated clockwise, and sun gear 10 is driven to rotate clockwise,
Sun gear 10 drives the rotation counterclockwise of planetary gear 12 and revolves clockwise around sun gear 10, because planet carrier 13 is in planetary gear 12
On, so planet carrier 13 is also rotated around the axis of sun gear 10 clockwise, on the other hand the second shaft 8 is rotated clockwise, band
The rotation counterclockwise of rotating ring shaped ring gear 11, the rotation counterclockwise of annular gear ring 11 drive the rotation counterclockwise of planetary gear 12, such planetary gear
12 rotational velocity is just further increased, and the increase of 12 rotational velocity of planetary gear makes the speed of planetary gear 12 to revolve clockwise
Degree increases, therefore the speed of planet carrier 13 is just further increased, and planet carrier 13 drives third shaft 18 to make differential reel 14
Rotation, thereby realizes first driving device and the second driving device drives the normal operation of headstock gear jointly, because first
The motor speed of driving device and the second driving device is equal and the number of teeth of sun gear 10 is equal with the number of teeth of first gear 6, institute
It is respectively that headstock gear provides the output power of half with first driving device and the second driving device, when one of driving
When device damages cisco unity malfunction, another driving device is still with original rotational speed, and planet carrier 13 is just with half
The rotation of former revolving speed, when slow than 10 turns of sun gear of annular gear ring 11, planet carrier 13 is also reporting with original half
Operating, transmission principle when the motor 2 of first driving device and the second driving device is rotated counterclockwise with identical revolving speed with
The transmission principle when motor 2 of first driving device and the second driving device is rotated clockwise with identical revolving speed is identical, here
Just no longer do excessive description.
For the use of the new type in use, first driving device and the second driving device provide power for headstock gear, one side is dynamic
Power passes to sun gear 10 by first rotating shaft 9；Sun gear 10 drives planetary gear 12, and planetary gear 12 drives planet carrier 13 to make planet
Frame 13 rotates, and on the other hand, first gear 6 drives annular gear ring 11 to rotate, and annular gear ring 11 drives planetary gear 12 to rotate, and makes to go
Star-wheel 12 is further driven to the rotation of planet carrier 13, and the rotation of such planet carrier 13 is just by first driving device and the second driving device
It is common that power is provided, when first driving device and the one of damage of the second driving device, planet carrier 13 with original two/
One rotation speed operation remains to normally rotate although the revolving speed of planet carrier 13 in this way is slack-off, and the then rotation of planet carrier 13 drives
Third shaft 18 rotates, and third shaft 18 rotates, and differential reel 14 is driven to rotate, and the rotation of differential reel 14 makes to be wrapped in difference
The length of wirerope 15 on fast reel 14 changes, and the drive of wirerope 15 is moved up and down by the gate that lifting lug connects, into
And the open and close of regulating gate.
Embodiment described above is not defined the scope of the utility model, is not departing from the utility model design
Under the premise of design, the various changes and improvements that technical staff described in this field makes the technical solution of the utility model,
It should be included in the protection scope of claims determination of the utility model.
