drive suspension 50 to rotate clockwise, and moved up and along the length side of wheel shaft 51 in rotation To motion.When driver element runs to Figure 12 states, swing span 10 has swung 33 °, and also drive shaft 20 of swing span 10 33 ° are have rotated, because drive sprocket 21 and drive sprocket 72 are rotated than being 1: 3 so that main shaft 20 is by drive sprocket 21 through first Chain 71 drives drive sprocket 72 to have rotated 99 ° of (first teeth counterclockwise by the driving cam 74 of power transmission shaft 73 and first gear 91 Wheel 91 belongs to idling conditions), driver element continues to run to Figure 13 states, when driver element runs to Figure 13 states, swing span 10 have swung 60 °, and also drive shaft 20 have rotated 60 ° to swing span 10, and main shaft 20 is by drive sprocket 21 through the first chain 71 drive drive sprockets 72 have rotated 180 ° counterclockwise by the driving cam 74 of power transmission shaft 73 and first gear 91, now, be in The driver element of rear stage initially enters working condition, and driver element continues to run from Figure 13 to Figure 14 states, from Figure 13 to During Figure 14, this driver element then does work with common rotated to main shaft 20 of rear stage driver element, on a left side for swing span 10 When Figure 14 states are swung under side, the whole process of swing span 10 has swung 63 °, meanwhile, swing span 10 drives also by ratchet mechanism 30 and led Axle 20 have rotated 63 °, and cam 74 and first gear 91 rotate 189 °, now, the first chimb 741 and the bottom of the second balancing weight 63 point From making swing span 10 and main shaft 20 be that synchronous interaction is closed while first gear 91 also rotates to part tooth and engaged with second gear 92 System, so far, driver element, which stops rotating main shaft 20, to do work, and two driver elements realize replacement and acting journey is rotated to main shaft 20 Sequence, main shaft 20 continues to rotate counterclockwise under the driving of rear stage driver element, and previous stage driver element exits work and entered Original state is returned, now, because the first chimb 741 is separated with the bottom of the second balancing weight 63, the second chimb 742 reply second is matched somebody with somebody Pouring weight 63 and separated state, make the left end of rotating turret 61 lose support force so that under the Action of Gravity Field of the second balancing weight 63, pressure It is pressed under the groove of wheels 62 on the screw thread chimb 531 of tapered thread wheel 53, makes the Gravity support point of the left end of rotating turret 61, from cam 74 are transferred to the screw thread chimb 531 of tapered thread wheel 53, make the gravity of the second balancing weight 63 and can be applied to cone by pressure wheel 62 On shape screw thread wheel 53, so that pressure assembly 60 has a downward gravity to pass gravity by suspension 50 and drawstring 40 It is handed to the right-hand member of swing span 10.Because pressure wheel 62 is to be articulated in the second balancing weight of left end 63 of rotating turret 61 and the right-hand member pivot of rotating turret 61 Middle part between contact, therefore, now pressure assembly 60 is applied with the gravity that twice of cam 74 is born to suspension 50, That is, when pressure wheel 74 bears institute's gravity for G, the gravity that now suspension 50 is born is two G.Thus include outstanding Hang the weight of component 50, left and right ends drawstring 40 has one to be more than pulling down for a G, at the same drawstring 40 also have one it is upward Reversal interlocking relay, because the right-hand member (from wheel shaft 51 to frame fixing point) of drawstring 40 is fixed in frame, thus, two downwards to On pulling force be equal.On the left side (from roller 52 to the right-hand member of swing span 10) of drawstring 40 it is connected on the right-hand member of swing span 10 , and swing span 10 is not fixed, as long as right-hand member applies downward pulling force and is more than the resistance that the first balancing weight 13 is produced Power, the right-hand member of swing span 10 can to lower swing, because the downward pulling force of right-hand member is the resistance that big first balancing weight 13 is produced, because This, the right-hand member of swing span 10 has the trend to lower swing under the pulling of drawstring 40, so that having one on two rollers 52 Individual anticlockwise revolving force, so that rotating the inverse time of roller 52, and is moved down and along the length side of wheel shaft 51 in rotation To motion, so as to drive the right of swing span 10 to raise the left side to lower swing, in the process, because roller 52 is and wheel shaft 51 And tapered thread wheel 53 is synchronous connection, therefore, tapered thread wheel 53 be also as roller 52 is 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 The contact point of screw thread chimb 531 and the groove of pressure wheel 62, can be incrementally increased, and be with moving down height with moving down in rotation Equal, that is to say, that the central point of wheel shaft 51 is moved downwardly how many, while driving tapered thread 53 to make in rotation is moved down The contact point of screw thread chimb 531 and the groove of pressure wheel 62 increases how many, the left end of rotating turret 61 is not moved down, second matches somebody with somebody The chimb 742 of pouring weight 63 and second keeps released state (as shown in figure 15).Thus, pressure assembly 60 can be made to have a gravity all the time It is applied on suspension 50, and the right-hand member of swing span 10 is delivered to through drawstring 40, makes the right-hand member of swing span 10 and suspension 50 Simultaneously to lower swing, during entirely original state is returned, due to the unidirectional drive performance of ratchet mechanism 30, the band of main shaft 20 Dynamic ratchet 31 is rotated counterclockwise, and swing span 10 is rotated clockwise with pawl 32, when first gear 91 turns to part tooth and the When two gears 92 are disengaged from, driver element revert to initial equilibrium state, matches somebody with somebody while cam 74 also rotates to the first chimb 741 with second The left end of the bottom of pouring weight 63 contact jack-up rotating turret 61, makes the groove of pressure wheel 62 be separated with screw thread chimb 531 so that pressure assembly 60 Gravity support point be transferred to top power component 70 by cam 74 as the strong point from suspension 50, thus relieve pressure assembly 60 gravity is transmitted to the path of the right-hand member of swing span 10 by suspension 50 and drawstring 40, the left end of swing span 10 is matched somebody with somebody first To lower swing under the Action of Gravity Field of pouring weight 13, driver element is again introduced into working condition and rotates acting to main shaft 20, repeats above-mentioned Process.Such iterative cycles so that under the mutual cooperation of two driver elements, main shaft 20 is able to lasting rotation and externally defeated Go out power.

Length direction (i.e. X to) arrangement of the main shaft 20 of two driver elements of the invention along frame simultaneously synchronously couples, institute State main shaft 20 and actually may be configured as one, 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 enter maintenance maintenance.Concrete implementation mode is：It is described to pass Movable sprocket 72 is provided with interior octet 721, and the end of power transmission shaft 73 sets octahedron, and the octahedron of power transmission shaft 73 can be inserted in transmission In the interior octet 721 of sprocket wheel 72, and the top edge of octet 721 offers screw hole and (not marked in figure in drive sprocket 72 Show), there is a screw 722 in screw hole, the screw 722 is connected on the octahedral one of face of the power transmission shaft 73, so that Power transmission shaft 73 is set to realize fixed relationship with drive sprocket 72；When there is driver element to need to overhaul maintenance, screw 722 is unclamped, The octahedron of drive sprocket 72 from power transmission shaft 73 is exited, and is then adjusted the power transmission shaft 73 of idle driver element, is made its cam 74 Angle and the angle of swing span and the phase of the driver element of pause are consistent, then drive sprocket 72 is reinstalled into power transmission shaft Screw 722 is tightened fixation by 73 octahedrons, and the locating dowel 223 on the clutch plate 22 of idle driver element is pushed into drive sprocket 21 Positioning hole 211, you can start the idle driver element, then will need overhaul driver element clutch plate 22, lead to pull bar 24 Clutch plate is pushed away into drive sprocket 21, locating dowel 223 is exited out of positioning hole 211, just can complete to suspend driver element to be repaired, But also as new idle driver element after maintenance, the failure driver element new for replacing.

In summary, the gravity that the present invention is produced using the first balancing weight 13 to the left end of swing span 10, then pass through ratchet machine Structure 30 puts on torque on main shaft 20, is that main shaft 20 provides the power source rotated, while being led to using the gravity of the second balancing weight 63 Rotating turret 61, pressure wheel 62 be applied to suspension 50 through drawstring 40 be transferred to the right-hand member of swing span 10 drive driver element revert to Original state, repetitive cycling is rotated to main shaft 20 and done work, and thus, can be made under the mutual cooperation of two driver elements, the present invention The rotation gone round and begun again is able to, so as to realize in the case of less without other power or other power, makes main shaft 20 constantly Rotate and externally export rotational power, therefore the present invention can reduce using coal, gasoline, the consumption of natural gas equal energy source, and And will not into atmospheric environment discharge harmful, reduce environmental pollution.
