force is lost, so that the screw thread for being pressed in screw thread wheel 53 under 62 groove of pressure wheel is convex under the gravity of the second clump weight 63 On side 531, so that the Gravity support point of 61 left end of rotating turret be made to be transferred to the pressure wheel 62 at middle part by suspension from cam 74 50 are used as supporting point, the separated state of the second chimb 742 and 63 bottom of the second clump weight, so that pressure assembly 60 has one Downward gravity is applied to the right end that suspension 50 is transferred to roller 10 through drawstring 40.So far, two driving units are completed Acting program alternately is rotated to main shaft 20, main shaft 20 continues to rotate counterclockwise under the driving of rear stage driving unit, previous stage Driving unit, which stops rotating main shaft 20 doing work and entering, returns original state program, at the same time, in the first chimb 741 and the Two clump weights, 63 bottom separate when, first gear 91 also just turns to part tooth and engages with second gear 92, make roller 10 and Main shaft 20 synchronizes, and roller 10 has the tendency that one rotates clockwise under the pulling of drawstring 40 at this time, while screw thread wheel 53 It counterclockwise and is moved down in rotation under the gravity of pressure wheel 62, so that roller 10 is driven to rotate clockwise, So that lifting rope 11 is wound to roller 10, so that the first clump weight 12 be driven to move up.In the process, due to idler wheel 52, wheel shaft 51 and screw thread wheel 53 are synchronous connections.Therefore screw thread wheel 53, wheel shaft 51 and idler wheel 52 are in rotation simultaneously to moving down Dynamic, and screw thread chimb 531 and the contact point of 62 groove of pressure wheel incrementally increase in rotation moves down.It is from wheel shaft 51 Central point can incrementally increase in rotation to the contact point of screw thread chimb 531 and 62 groove of pressure wheel with moving down, and under It is same for moving height.That is, the central point of wheel shaft 51 is moved downwardly how many, while screw thread wheel 53 is in moving down rotation Make screw thread chimb 531 and 62 groove contact point of pressure wheel increase how many, keeps rotating turret 61 not past under the action of screw thread wheel 53 Lower movement makes the second chimb 742 and 63 bottom of the second clump weight keep discrete state (as shown in figure 16), thus may make pressure Component 60 has a downward gravity to be applied on suspension 50 always, and power source is transmitted to the right side of roller 10 through drawstring 40 End haulage drum 10 rotates clockwise, so that lifting rope 11 be made to wind to roller 10, the first clump weight 12 is thus driven to move up, During entirely returning original state, due to the unidirectional drive performance of ratchet mechanism 30, main shaft 20 is in subsequent drive unit Driving under drive ratchet 31 continue to rotate counterclockwise, roller 10 then band pawl 32 rotate clockwise, when 91 turns of first gear It moves part tooth and second gear 92 is detached from driving relationship, driving unit revert to original state, while cam 74 also rotates to First chimb 741 is contacted with the second clump weight 63 jacks up 61 left end of rotating turret, makes the Gravity support point of pressure assembly 60 from suspention Component 50 is transferred to cam 74, thus relieves pressure assembly 60 and is applied through drawstring 40 to 10 right end of roller by suspension 50 Gravity, rotate counterclockwise roller 10 under the gravity of the first clump weight 12, driving unit is again introduced into working condition Main shaft 20 is rotated and is done work, is repeated the above process, such repetitive cycling, makes the present invention in the mutual cooperation of two driving units Under, main shaft 20 is able to lasting rotation and external output power.

The main shaft 20 of two driving units of the invention is arranged successively along the length direction (i.e. X to) of rack and synchronizes connection It connects, the main shaft 20 actually may be configured as one, and two driving units share the main shaft 20.
