In Figure 14 states, and cause the second driver element in Figure 14 states is in be rotated to main shaft 20 among acting.So that
Obtain of the invention complete after installing i.e. with initial launch function.
The present invention is when running well, and the locating dowel 223 of clutch plate 22 is inserted in the positioning hole 211 of drive sprocket 21,
Make main shaft 20 and relation that drive sprocket 21 is synchronous connection;
Wherein, the operation principle of the present invention is illustrated with Figure 12 state-drivens unit:
Work(haulage drum 10 is done to main shaft 20 with driver element and rotates 380 degree, cam 74 rotates 190 degree.First is convex
Side 741 contacts 190 degree of the anglec of rotation with the second balancing weight 63, and the second chimb 742 reply the second balancing weight 63 anglec of rotation is 170
Exemplified by degree, during original state, main shaft 20 drives the first sprocket wheel 72 to rotate counterclockwise by drive sprocket 21 through the first chain 71, the
One sprocket wheel 72 is rotated counterclockwise through rotating shaft 73 with moving cam 74 and first gear 91, makes the first chimb 741 and second of cam 74
The contact of balancing weight 63 and the left end of jack-up rotating turret 61, make the groove of pressure wheel 62 be separated with screw thread chimb 531 so that in roller 10
Right-hand member only has the gravity that suspension 50 applies through drawstring 40, so that the left end of roller 10 is made in the gravity of the first balancing weight 12
Rotated counterclockwise under, and main shaft 20 is transmitted to by ratchet mechanism 30, rotated for main shaft 20 and power source is provided.Now first gear
91 belong to idling conditions.Drawstring 40 is wound to roller 10 when roller 10 is rotated counterclockwise simultaneously, thus drive suspension
50 rotate clockwise, and move up and moved along the length direction of wheel shaft 51 in rotation.When driver element run to
During Figure 14 states, the haulage drum 10 of the first balancing weight 12 has rotated counterclockwise 360 degree, and roller 10 is driven by ratchet mechanism 30 and led
Axle 20 has rotated counterclockwise 360 degree, and main shaft 20 is rotated counterclockwise by drive sprocket 21 with moving cam 74 and first gear 91
180 degree, is now in rear stage driver element and initially enters working condition, driver element continues to transport from Figure 14 to Figure 15 states
OK, during the state from Figure 14 to Figure 15 is run, this driver element is rotated to main shaft 20 jointly with rear stage driver element
Acting, when driver element is run to Figure 15 states, the haulage drum 10 of the first balancing weight 12 has rotated counterclockwise 380 degree, roller
10 have rotated counterclockwise 380 degree by the drive shaft 20 of ratchet mechanism 30, and cam 74 and first gear 91 have rotated 190 degree, this
When, the first chimb 741 is separated with the bottom of the second balancing weight 63, and the second chimb 742 tackles the bottom of the second balancing weight 63, rotating turret
61 left ends lose support force so that under the Action of Gravity Field of the second balancing weight 63, and tapered thread wheel is pressed under the groove of pressure wheel 62
On 53 screw thread chimb 531, so that the Gravity support point of the left end of rotating turret 61 is transferred to the pressure wheel 62 at middle part from cam 74
The strong point, the separated state of the second chimb 742 and the bottom of the second balancing weight 63, so that pressure group are used as by suspension 50
Part 60 has a downward gravity to be applied to the right-hand member that suspension 50 is transferred to roller 10 through drawstring 40.So far, two are completed
Individual driver element alternately rotates acting program to main shaft 20, and main shaft 20 continues to turn counterclockwise under the driving of rear stage driver element
Dynamic, previous stage driver element, which stops rotating main shaft 20, does work and enters the original state program that returns, at the same time, convex first
When side 741 is separated with the bottom of the second balancing weight 63, first gear 91 also just turns to part tooth and engaged with second gear 92, makes
Roller 10 and the same linkage of main shaft 20, simultaneously as pressure wheel 62 is to be articulated in the second balancing weight of left end 63 of rotating turret 61 with rotating
Middle part between the right-hand member pivoting point of frame 61, therefore, now pressure assembly 60 is applied with twice of cam 74 to suspension 50 and held
The gravity received, that is, when cam 74 bears institute's gravity for G, the gravity that now suspension 50 is born is two G, thus
Include the gravity of suspension 50, have a downward pulling force for being more than a G (because cam 74 is held in the drawstring 40 of the right and left
Do not included the gravity of suspension 50 by institute's gravity), while drawstring 40 also has a upward reversal interlocking relay, due to drawstring 40
Right section is fixed in frame, thus, and two downward upward pulling force are equal.At left section of drawstring 40, due to being to be connected to
On roller 10, and roller 10 is not fixed, as long as the pulling force that rotates clockwise that the right-hand member of roller 10 applies is more than a left side
The resistance for holding the first balancing weight 12 to produce, what roller 10 can be rotated clockwise, therefore, pulling of the right-hand member of roller 10 in drawstring 40
Under have the trend rotated clockwise so that having an anticlockwise revolving force on roller 52, so that roller 52
Counterclockwise, and moved down and along the motion of the length direction of wheel shaft 51 in rotation, so as to drive roller 10 to turn clockwise
It is dynamic, so that lifting rope 11 is wound to roller 10, so as to drive the first balancing weight 12 to move up.In the process, due to rolling
Wheel 52, wheel shaft 51 and tapered thread wheel 53 are synchronous connections.Therefore, tapered thread wheel 53 is also with wheel shaft 51 and roller 52
Moved down in rotation, and the contact point of screw thread chimb 531 and the groove of pressure wheel 62 is incrementally increased in rotation is moved down.
Be from the central point of wheel shaft 51 to screw thread chimb 531 with the contact point of the groove of pressure wheel 62, can with move down in rotation by
Step increase, and be equal with moving down height.That is, the central point of wheel shaft 51 is moved downwardly how many, drive simultaneously
Tapered thread wheel 53 makes screw thread chimb 531 increases how many with the groove contact point of pressure wheel 62 in rotation is moved down, and makes rotating turret
61 do not move down in the presence of tapered thread wheel 53, make the second chimb 742 keep separating shape with the bottom of the second balancing weight 63
State (as shown in figure 16), thus, may be such that pressure assembly 60 has a downward gravity to be applied on suspension 50 all the time, and
Power source is delivered to the right-hand member of roller 10 through drawstring 40, roller 10 is rotated clockwise, so that lifting rope 11 is wound to roller 10,
Thus the first balancing weight 12 is driven to move up, it is unidirectional due to ratchet mechanism 30 during entirely original state is returned
Driveability, main shaft 20 drives ratchet 31 to continue to rotate counterclockwise under the driving of subsequent drive unit, and roller 10 then drives spine
Pawl 32 is rotated clockwise, and when first gear 91 turns to part tooth and the disengaging driving relationship of second gear 92, driver element is returned
To original state, while cam 74 also rotates to the first chimb 741 contacts the left end of jack-up rotating turret 61 with the second balancing weight 63, make
The Gravity support point of pressure assembly 60 is transferred to cam 74 from suspension 50, and driver element is again introduced into working condition to main shaft
20 rotate acting, repeat said process, and such repetitive cycling makes the present invention under the mutual cooperation of two driver elements, main shaft
20 are able to lasting rotation and externally export power.
