Wherein, the operation principle of the present invention is illustrated with Figure 11 state-drivens unit：

63 ° are rotated with driver element drive shaft 20 of acting, the gearratio of 21 and first sprocket wheel of drive sprocket 72 is 1: 3, it is 189 degree that the first chimb 741, which contacts the anglec of rotation with the second balancing weight 63, and the second chimb 742 tackles the second balancing weight 63 The anglec of rotation is exemplified by 171 degree, during original state, driver element is in position as shown in figure 11, and main shaft 20 passes through drive sprocket The counterclockwise of 21 driving top power component 70, makes the first chimb 741 and the second balancing weight 63 of cam 74 abut against jack-up rotation The left end of frame 61 so that the downward Gravity support of pressure assembly 60 is on cam 74, now, the groove of pressure wheel 62 and tapered thread The screw thread chimb 531 of wheel 53 belongs to released state, also, pressure wheel 62 is in and the highest of 53 screw thread chimb of tapered thread wheel 531 Place, suspension 50 is in extreme lower position.In the right-hand member of swing span 10, the weight that only suspension 50 is applied by drawstring 40 Amount.Now, the gravity of the first balancing weight of the left side 13 of swing span 10 is more than pulling force and swing span of the drawstring 40 to the right-hand member of swing span 10 10 left sides rotate required weight toward drive shaft during lower swing 20, and therefore, the left end of swing span 10 is in the first balancing weight 13 To lower swing under Action of Gravity Field so that swing arm 11 drives the counterclockwise of annulus 34, so as to promote ratchet 31 with pawl 32 Counterclockwise, because ratchet 31 and main shaft 20 are synchronous connections, ratchet 31 drives the counterclockwise of main shaft 20 again, so that Main shaft 20 externally output power, at the same time, right-hand member is raised when the left side of swing span 10 is toward lower swing so that two drawstrings 40 to Upper movement, thus drives suspension 50 to rotate clockwise, and moved up and along the length direction of wheel shaft 51 in rotation Motion.When driver element runs to Figure 13 states, swing span 10 has swung 60 °, and swing span 10 is also by ratchet mechanism 30 drive shafts 20 have rotated 60 °, because the sprocket wheel 72 of drive sprocket 21 and first is rotated than being 1: 3 so that main shaft 20 passes through actively Sprocket wheel 21 drives the first sprocket wheel 72 anti-by the driving cam 74 of rotating shaft 73, the 3rd gear 75 and first gear 91 through the first chain 71 Hour hands have rotated 180 ° (first gear 91 belongs to idling conditions), and now, the driver element for being in rear stage initially enters work State, driver element continue from Figure 13 to Figure 14 states run, during from Figure 13 to Figure 14, this driver element then with it is rear Common rotated to main shaft 20 of one-level driver element is done work, and when Figure 14 states are swung under the left side of swing span 10, swing span 10 is complete Journey has swung 63 °, meanwhile, swing span 10 have rotated 63 °, cam 74, the 3rd gear also by the drive shaft 20 of ratchet mechanism 30 75 and 189 ° of 91 counterclockwise of first gear, now, the first chimb 741 is separated with the bottom of the second balancing weight 63, while first Gear 91 also rotates to part tooth and engaged with second gear 92, and it is synchronous with main shaft 20 in original state is returned to make driver element Interaction relation, so far, driver element, which stops rotating main shaft 20, to do work, and thus two driver elements realize replacement to main shaft 20 Acting program is rotated, main shaft 20 continues to rotate counterclockwise under the driving of rear stage driver element, and previous stage driver element is exited Work and enter and return original state program, now because the first chimb 741 is separated with the bottom of the second balancing weight 63, the second chimb 742 the second balancing weights 63 of reply and separated state, make the left end of rotating turret 61 lose support force so that in the second balancing weight 63 Under Action of Gravity Field, it is pressed under the groove of pressure wheel 62 on the screw thread chimb 531 of tapered thread wheel 53, makes the support of the left end of rotating turret 61 Point, the screw thread chimb 531 of tapered thread wheel 53 is transferred to from cam 74, makes the gravity of the second balancing weight 63 can be by pressure wheel 62 It is applied on tapered thread wheel 53, so that pressure assembly 60 has a downward gravity to pass through suspension 50 and drawstring 40 By weight transfer 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 rotating turret Middle part between 61 right-hand member pivoting points, therefore, now pressure assembly 60 is applied with twice of cam 74 to suspension 50 and born Gravity, that is to say, that pressure wheel 74 bear institute's gravity for G when, the gravity that now suspension 50 is born be two G.By This includes the weight of suspension 50, and the drawstring 40 of left and right ends has one to be more than pulling down for a G, while drawstring 40 also has One 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 downward upward pulling force are equal.It is to be connected to swing on the left side (from roller 52 to the right-hand member of swing span 10) of drawstring 40 On the right-hand member of frame 10, and swing span 10 is not fixed, as long as right-hand member applies downward pulling force and is more than the first balancing weight 13 resistances produced, the right-hand member of swing span 10 can be to lower swing, because the downward pulling force of right-hand member is that big first balancing weight 13 is produced Resistance, therefore, the right-hand member of swing span 10 has the trend to lower swing under the pulling of drawstring 40, and suitable in pressure wheel 62 In the presence of the rotatory force of hour hands is to screw thread chimb 531, tapered thread wheel 53, roller 52 and wheel shaft 51 have a rotation counterclockwise Turn power, so that tapered thread wheel 53, roller 52 and the rotation of the inverse time of wheel shaft 51, and moved down and along wheel shaft in rotation 51 length directions are moved, 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 It is synchronous connection with wheel shaft 51 and tapered thread wheel 53, therefore tapered thread wheel 53 is also as wheel shaft 51 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.It is from wheel shaft 51 Heart point can be incrementally increased to screw thread chimb 531 and the contact point of the groove of pressure wheel 62 with moving down in rotation, and with moving down Height is equal, that is to say, that the central point of wheel shaft 51 is moved downwardly how many, while driving tapered thread 53 in lower transfer Make screw thread chimb 531 and the contact point of the groove of pressure wheel 62 increase how many in dynamic, the left end of rotating turret 61 is not moved down, Second balancing weight 63 and the second chimb 742 keep released state (as shown in figure 15).Thus pressure assembly 60 can be made to have one all the time Individual gravity is applied on suspension 50, and is delivered to the right-hand member of swing span 10 through drawstring 40, makes the right-hand member of swing span 10 and suspention Component 50 is simultaneously to lower swing, during entirely original state is returned, main due to the unidirectional drive performance of ratchet mechanism 30 Axle 20 drives ratchet 31 to rotate counterclockwise, and swing span 10 is rotated clockwise with pawl 32, when first gear 91 turns to part When tooth and second gear 92 are disengaged from, driver element revert to initial equilibrium state, at the same cam 74 also rotate to the first chimb 741 with The left end of the bottom of second balancing 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 The Gravity support point of component 60 is transferred to top power component 70 by cam 74 as the strong point from suspension 50, thus relieves pressure The gravity of power component 60 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 existed To lower swing under the Action of Gravity Field of first balancing weight 13, driver element is again introduced into working condition and acting, weight is rotated to main shaft 20 Multiple said process.Such repetitive cycling so that under the mutual cooperation of two driver elements, main shaft 20 is able to lasting rotation simultaneously Externally export 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：Described One sprocket wheel 72 is provided with interior octet 721, and the end of rotating shaft 73 sets octahedron, and the octahedron of rotating shaft 73 can be inserted in the first sprocket wheel In 72 interior octet 721, meanwhile, the top edge of octet 721 offers screw hole (not indicated in figure) in the first sprocket wheel 72, There is a screw 722 in screw hole, the screw 722 is connected on the octahedral one of face of the rotating shaft 73, so that rotating shaft 73 and first sprocket wheel 72 realize fixed relationship；When there is driver element to need to overhaul maintenance, screw 722 is unclamped, the first sprocket wheel 72 exit from the octahedron of rotating shaft 73, then adjust the rotating shaft 73 of idle driver element, make the angle and swing span of its cam 74 Angle and the phase of driver element of pause be consistent, then that the first sprocket wheel 72 is reinstalled into rotating shaft 73 is octahedra by screw 722 tighten fixation, the locating dowel 223 on the clutch plate 22 of idle driver element are pushed into the positioning hole 211 of drive sprocket 21, i.e., The idle driver element can be started, the clutch plate 22 of maintenance driver element then will be needed, clutch plate is pushed away master by logical pull bar 24 Movable sprocket 21, makes locating dowel 223 be exited out of positioning hole 211, just can complete to suspend driver element to be repaired, after maintenance but also as New idle driver element, 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.
