condition, meanwhile, the driver element of previous stage then exits working condition.Driver element continues to transport from Figure 12 to Figure 13 states OK, during from Figure 12 to Figure 13, this driver element then does work to main shaft 20 jointly with rear stage driver element, (from figure 11 to Figure 12 are done work with common rotated to main shaft 20 of previous stage driver element), Figure 13 shapes are swung under the left side of swing span 10 During state, the whole process of swing span 10 has swung 60 °, meanwhile, swing span 10 have rotated 60 ° also by the drive shaft 20 of ratchet mechanism 30, Cam 107 and first gear 91 have rotated 180 °, now, and the second chimb 1072 of cam 107 is separated with pulley 103, and first is convex Side 1071 contacts with pulley 103 and the left end of rotating turret 101 is pressed down, meanwhile, the part tooth of first gear 91 and second gear 92 Engagement makes swing span 10 and main shaft 20 be synchronous interaction relations, so far, and driver element, which stops rotating main shaft 20, to do work, main shaft 20 Continue to rotate counterclockwise under the driving of driver element below.Now because cam 107 is under the compressing of the left end of rotating turret 101, So that the right-hand member of rotating turret 101 is moved up in the presence of pressure wheel 102, so that cylinder 108 produces pressure to stage clip 110 Contracting is acted on, while stage clip 110 also produces a reverse pressure to cylinder 108 so that rotating turret 101 have one it is downward Pressure is applied on suspension 50 by pressure wheel 102, and power source is delivered to the right-hand member of swing span 10 through drawstring 40.Due to pressure Wheels 102 is the middle part for being articulated in rotating turret 101, that is, the left end pulley 103 of rotating turret 101 is pivotally connected to the right-hand member of rotating turret 101 Middle part between point, therefore, now pressure assembly 100 is applied with the pressure produced by twice of stage clip 110 to suspension 50, That is when the pressure that stage clip 110 is produced is G, the pressure that now suspension 50 is born is more than two G (including rotating turrets The weight that 101 pressure wheels 102 apply).Therefore, there is a downward pulling force for being more than a G in the drawstring 40 of the right and left, simultaneously Two drawstrings 40 also have a upward reversal interlocking relay, because right section (from wheel shaft 51 to frame fixing point) of drawstring 40 is fixed on machine On frame, thus two downward upward pulling force are equal.At left section (from roller 52 to the right-hand member of swing span 10) of drawstring 40, by Then it is connected on the right-hand member of swing span 10, and swing span 10 is not fixed, as long as the right-hand member of swing span 10 is downward Pulling force is more than the resistance that the left end balancing weight 13 of swing span 10 is produced, and the right-hand member of swing span 10 is i.e. to lower swing.Therefore, swing span 10 is right When generation downward pulling force in end is more than the gravity of the left end balancing weight 13 of swing span 10, swing span 10 has becoming to lower swing Gesture, so that having an anticlockwise rotation force on roller 52 and wheel shaft 51, so that roller 52 and wheel shaft 51 are anti- Shi Xuanzhuan, and moved down and along the motion of the length direction of wheel shaft 51 in rotation, so as to drive the right of swing span 10 to the bottom It is dynamic to raise the left side, in the process, due to roller 52 be with wheel shaft 51 and tapered thread wheel 53 be it is synchronous couple, therefore, Tapered thread wheel 53 is also and screw thread chimb 531 and pressure wheel in rotation is moved down as wheel shaft 51 is moved down in rotation The contact point of 102 grooves is incrementally increased, and is to be connect from the central point of wheel shaft 51 to screw thread chimb 531 with the groove of pressure wheel 102 Contact, can be incrementally increased, and be equal with moving down height, that is to say, that the central point of wheel shaft 51 with moving down in rotation Be moved downwardly how many, at the same drive tapered thread 53 move down rotate in make connecing for screw thread chimb 531 and the groove of pressure wheel 102 Contact increases how many, rotating turret 101 is not moved down in the presence of tapered thread wheel 53, the first 1071 pairs of chimb cunning Wheel 103 is maintained at pressed status (as shown in figure 14).Thus pressure assembly 100 can be made to have a downward pressure to be applied to all the time On suspension 50, and power source is delivered to through drawstring 40 right-hand member of swing span 10, makes the right-hand member of swing span 10 and suspension 50 Simultaneously to lower swing, left end is raised, at the same time, in 10 clockwise oscillation of swing span, due to the unidirectional drive of ratchet mechanism 30 Dynamic performance, now main shaft 20 drive ratchet 31 to continue to rotate counterclockwise under the driving of subsequent drive unit, the then band of swing span 10 Pawl 32 is rotated clockwise, and the front end of ratchet 32 is slipped over from the back of tooth of ratchet 31, when being rotated by main shaft 20 of cam 107 After 180 ° so that the first chimb 1071 is separated with pulley 103, second chimb 1072 reply pulley 103 and separated state turn The left end of moving frame 101 loses the state of being pressed down, and pressure assembly 100 is applied with the pressure releases of suspension 50, in the right-hand member of swing span 10 Gravity produced by suspension 50 and the pressure wheel 102 of rotating turret 101 that only drawstring 40 applies, while first gear 91 Turn to part tooth and be disengaged from driving condition with second gear 92, so far, driver element revert to original state and in counterweight The left end of Action of Gravity Field bottom moving frame 10 of block 13 to lower swing, driver element be again introduced into main shaft 20 rotate do work, repeat with The upper course of work.Such iterative cycles so that under the mutual cooperation of four driver elements, main shaft 20 is able to lasting rotation simultaneously Externally export power.

Length direction (i.e. X to) of the main shaft 20 of four 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 four driver elements share the main shaft 20.

Referring to Fig. 8, as a further improvement, except aforementioned four driver element, an idle driving also can be set Unit, when one of failure of aforementioned four 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, concrete implementation mode is：First sprocket wheel 105 is provided with interior Octet 1051, end of rotating shaft 106 is set to octahedra, and the octahedron of rotating shaft 106 can be inserted in interior the eight of the first sprocket wheel 105 In angle body 1051, meanwhile, the top edge of octet 1051 offers screw hole (not indicated in figure), screw in the first sprocket wheel 105 There is a screw 1052 in hole, screw 1052 is connected on the octahedral one of face of the rotating shaft 106, so that rotating shaft 106 Fixed relationship is realized with the first sprocket wheel 105；When there is driver element to need to overhaul maintenance, screw 1052 is unclamped, the first sprocket wheel 105 exit from the octahedron of rotating shaft 106, then adjust the rotating shaft 106 of idle driver element, make the angle and pendulum of its cam 107 The angle of moving frame 10 and the angle of the driver element of pause are consistent, then the first sprocket wheel 105 is reinstalled into the octahedral of rotating shaft 106 Screw 1052 is tightened fixation by body, and the locating dowel 223 on the clutch plate 22 of idle driver element is pushed into determining for drive sprocket 21 Position hole 211, you can start the idle driver element, then will need to overhaul the clutch plate 22 of driver element, leading to pull bar 24 will be from Plywood pushes away drive sprocket 21, locating dowel 223 is exited out of positioning hole 211, just can complete to suspend driver element to be repaired, maintenance Afterwards but also as new idle driver element, the failure driver element new for replacing.

In summary, the gravity that the present invention is produced to the left end of swing span 10 using balancing weight 13 is by ratchet mechanism 30 by power Square is put on main shaft 20, is that main shaft 20 provides the power source rotated, the pressure produced using pressure assembly 100 is through suspension 50 and drawstring 40 power source is applied to the right-hand member of swing span 10 in the way of transmitting, drive driver element to 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 four driver elements, the present invention is able to Zhou Erfu The rotation of beginning, so as to realize in the case of less without other power or other power, makes main shaft 20 constantly rotate, so that right Outer output rotational power, therefore, the present invention can reduce using coal, gasoline, the consumption of natural gas equal energy source, and will not be to Discharge harmful in atmospheric environment, reduces environmental pollution.
