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.

Length direction (i.e. X to) of the main shaft 20 of two driver elements of the invention along frame is arranged in order and synchronously joined Connect, the main shaft 20 actually may be configured as one, and two driver elements share the main shaft 20.

Referring to Fig. 8, as a further improvement, except above-mentioned two driver element, an idle driving also can be set Unit, when one of failure of above-mentioned two driver element needs repairing, suspends the driver element, and start described Idle driver element just can, thus can make to be not required to overall shutdown, you can carry out maintenance maintenance, concrete implementation mode is：It is described First sprocket wheel 72 is provided with interior octet 721, and the end of rotating shaft 73 is set to octahedra, and the octahedron of rotating shaft 73 can be inserted in first In the interior octet 721 of sprocket wheel 72, meanwhile, the top edge of octet 721 offers screw hole and (not marked in figure in the first sprocket wheel 72 Show), there is a screw 722 in screw hole, screw 722 is connected on the octahedral one of face of the rotating shaft 73, so that turning The sprocket wheel 72 of axle 73 and first realizes fixed relationship；When there is driver element to need to overhaul maintenance, screw 722 is unclamped, the first chain Wheel 72 is exited from the octahedron of rotating shaft 73, is then adjusted the rotating shaft 73 of idle driver element, is made angle and the pause of its cam 74 The phase of driver element be consistent, then the first sprocket wheel 72 is loaded into the octahedron of rotating shaft 73 screw 722 is tightened into fixation, Locating dowel 223 on the clutch plate 22 of idle driver element is pushed into the positioning hole 211 of drive sprocket 21, you can start the free time Driver element, then will need the clutch plate 22 of maintenance driver element, and clutch plate is pushed away drive sprocket 21 by logical pull bar 24, and it is fixed to make Position post 223 is exited out of positioning hole 211, just can complete to suspend driver element to be repaired, is driven after maintenance but also as the new free time Unit, the failure driver element new for replacing.

In summary, the gravity that the present invention is applied using the first balancing weight 12 to the left end of roller 10, passes through ratchet mechanism 30 Torque is put on main shaft 20, is that main shaft 20 provides the power source rotated, using the gravity of pressure assembly 60 through suspension 50 And drawstring 40 is applied to the right-hand member of roller 10 in the way of transmission, driver element is driven to revert to original state repetitive cycling to master Axle 20 rotates acting, thus, can make under the mutual cooperation of two driver elements, and the present invention is able to the rotation gone round and begun again, from And realize in the case of less without other power or other power, main shaft 20 is constantly rotated, and power is externally exported, because This, the present invention can reduce coal, gasoline, the consumption of natural gas equal energy source, and nuisance will not be discharged into atmospheric environment Matter, reduces environmental pollution.

Also it can make a kind of for making sight, and be adapted to the handicraft that various occasions are laid in accordance with the above.Make The present invention realizes maximum economic value.
