Figure 11 to Figure 14 is referred to, it is the signal of the invention in four kinds of different working conditions：

Wherein, Figure 11 is that driver element initially enters working state schematic representation, and Figure 12 is that driver element is in working condition In, Figure 13 is that driver element is exited in working condition, and Figure 14 is that driver element is returned in original state, four driver elements it is convex Wheel 103 is in the staggered installation of an angle of 90 degrees in frame, and the swing span 10 for making four driver elements is in such as Figure 15 from the side Shown, when being in Figure 11 states with the first driver element, the second driver element is then in Figure 12 states, and the 3rd driver element is in Figure 13 states, the 4th driver element is then between Figure 14 state positions and original state.And second in Figure 12 states drives Moving cell is among main axis acting, making the present invention complete after installing i.e. with AutoPlay function.

The present invention is when running well, and the locating dowel 223 of clutch plate 22 is inserted in the positioning hole 211 of drive sprocket 21, Now main shaft 20 and drive sprocket 21 are the relations of synchronous connection；

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

Main shaft 20 is rotated with driver element and does a work(, swing span 10 swings 60 °, the sprocket wheel of drive sprocket 21 and first Exemplified by 105 gearratio 1: 3, during original state, driver element is in state as shown in figure 11, now, the second of cam 107 Chimb 1072 tackles pulley 103 and separated state, the right-hand member of swing span 10 only have the suspension 50 that drawstring 40 applies and Weight produced by rotating turret 101, pressure wheel 102.The gravity of the left side balancing weight 13 of swing span 10 is more than drawstring 40 to swing span 10 The pulling force of right-hand member and the left side of swing span 10 toward drive shaft during lower swing 20 rotate when required weight, therefore, swing span 10 left ends under the Action of Gravity Field of balancing weight 13 to lower swing so that swing arm 11 drives the counterclockwise of annulus 34, by This band pawl 32 promotes the counterclockwise of ratchet 31, and because ratchet 31 and main shaft 20 are synchronous connections, ratchet 31 drives again The counterclockwise of main shaft 20, so that the external output power of main shaft 20, at the same time, on the left side of swing span 10 toward lower swing right-hand member When raising, move up two drawstrings 40, thus drive suspension 50 to rotate clockwise, and move up in rotation and Along the motion of the length direction of wheel shaft 51, when driver element runs to Figure 12 states, swing span 10 has swung 30 °, and swings Frame 10 has rotated counterclockwise 30 ° also by the drive shaft 20 of ratchet mechanism 30, meanwhile, because of the sprocket wheel 105 of drive sprocket 21 and first Gearratio is 1: 3, that is, drive sprocket 21 rotates a circle and the first sprocket wheel 105 can be driven to rotate three circles by the first chain 104, So that main shaft 20 passes through drive sprocket 21, the first chain 104, the first sprocket wheel 105 and the driving cam 107 of rotating shaft 106, the 3rd gear 112 and first gear 91 have rotated 90 ° (the 3rd gear 112 and first gear 91 belong to idling conditions) counterclockwise, now, be in The driver element of rear stage initially enters working condition, meanwhile, the driver element of previous stage then exits working condition.Driver element Continue from Figure 12 to Figure 13 states run, during from Figure 12 to Figure 13, this driver element then with rear stage driver element Main shaft 20 is done work jointly, (from Figure 11 to Figure 12 being done work with common rotated to main shaft 20 of previous stage driver element) is swinging When Figure 13 states are swung under the left side of frame 10, the whole process of swing span 10 has swung 60 °, meanwhile, swing span 10 is also by ratchet mechanism 30 drive shafts 20 have rotated 60 °, and cam 107 and first gear 91 have rotated 180 °, now, the second chimb of cam 107 1072 are separated with pulley 103, and the first chimb 1071 is contacted with pulley 103 and the left end of rotating turret 101 pressed down, first gear 91 Part tooth is engaged with second gear 92 makes swing span 10 and main shaft 20 be synchronous interaction relations, meanwhile, the 3rd gear 112 is also rotated Engaged to part tooth with the 4th gear 81, so far, driver element, which stops rotating main shaft 20, to do work, and main shaft 20 is driving list below Continue to rotate counterclockwise under the driving of member.Now because cam 107 is under the compressing of the left end of rotating turret 101 so that rotating turret 101 Right-hand member moved up in the presence of pressure wheel 102 so that cylinder 108 to stage clip 110 produce compression, simultaneously press Spring 110 also produces a reverse pressure to cylinder 108, so that rotating turret 101 has a downward pressure to pass through pressure wheel 102 are applied on suspension 50, and power source is delivered to the right-hand member of swing span 10 through drawstring 40.Because pressure wheel 102 is pivot joint At the middle part of rotating turret 101, that is, the middle part that the left end pulley 103 of rotating turret 101 is arrived between the right-hand member pivoting point of rotating turret 101, Therefore, now pressure assembly 100 is applied with the pressure produced by twice of stage clip 110 to suspension 50, that is to say, that in stage clip When 110 pressure produced are G, the pressure that now suspension 50 is born is more than two G, and (including the pressure wheel 102 of rotating turret 101 is applied Plus weight).Therefore, there is a downward pulling force for being more than a G in the drawstring 40 of the right and left, while two drawstrings 40 also have one Individual upward reversal interlocking relay, because right section (from wheel shaft 51 to frame fixing point) of drawstring 40 is fixed in frame, thus two Upward pulling force is equal downwards.At left section (from roller 52 to the right-hand member of swing span 10) of drawstring 40, due to being to be connected to pendulum On the right-hand member of moving frame 10, and swing span 10 is not fixed, is swung as long as the downward pulling force of the right-hand member of swing span 10 is more than The resistance that the left end balancing weight 13 of frame 10 is produced, the right-hand member of swing span 10 is i.e. to lower swing.Therefore, the right-hand member of swing span 10 is produced downwards When pulling force is more than the gravity of the left end balancing weight 13 of swing span 10, swing span 10 has the trend to lower swing, and in pressure wheel In the presence of 102 clockwise power of walking around are to screw thread chimb 531, there is one on tapered thread wheel 53, roller 52 and wheel shaft 51 Anticlockwise rotation force, so that 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 With wheel shaft 51 and tapered thread wheel 53 be it is synchronous connection, therefore, tapered thread wheel 53 be also with wheel shaft 51 in rotation under Move, and the contact point of screw thread chimb 531 and the groove of pressure wheel 102 is incrementally increased in rotation is moved down, and is from wheel shaft 51 Central point to the contact point of screw thread chimb 531 and the groove of pressure wheel 102, can be incrementally increased with moving down in rotation, and It is equal with moving down height, that is to say, that the central point of wheel shaft 51 is moved downwardly how many, while driving tapered thread 53 to exist Moving down in rotation makes screw thread chimb 531 and the contact point of the groove of pressure wheel 102 increase how many, makes rotating turret 101 in taper spiral shell Do not moved down in the presence of line wheel 53, the first chimb 1071 is maintained at pressed status (as shown in figure 14) to pulley 103.Thus Pressure assembly 100 can be made to have a downward pressure to be applied on suspension 50 all the time, and be delivered to power source through drawstring 40 The right-hand member of swing span 10, makes the right-hand member of swing span 10 with suspension 50 simultaneously to lower swing, left end is raised, at the same time, in pendulum During 10 clockwise oscillation of moving frame, due to the unidirectional drive performance of ratchet mechanism 30, now drive of the main shaft 20 in subsequent drive unit Dynamic lower drive ratchet 31 continues to rotate counterclockwise, and then band pawl 32 is rotated clockwise swing span 10, and the front end of ratchet 32 is from spine Take turns 31 back of tooth to slip over, when cam 107 is in main shaft 20 after being rotated by 180 ° so that the first chimb 1071 and pulley 103 Separation, the second chimb 1072 reply pulley 103 and separated state, the left end of rotating turret 101 lose the state of being pressed down, pressure assembly 100 are applied with the pressure releases of suspension 50, there was only the suspension 50 and rotating turret that drawstring 40 applies in the right-hand member of swing span 10 Gravity produced by 101 pressure wheels 102, while first gear 91 also rotates to part tooth is disengaged from driving with second gear 92 State, the 3rd gear 112 also rotates to part tooth and the 4th gear 81 is disengaged from driving condition, so far, and driver element is returned To original state and balancing weight 13 the left end of Action of Gravity Field bottom moving frame 10 to lower swing, driver element is again introduced into main shaft 20 rotate acting, repeat the above course of work.Such iterative cycles so that under the mutual cooperation of four 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 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 power source is applied to the right-hand member of swing span 10 by drawstring 40 in the way of transmitting, driver element is driven to revert to original state, weight Multiple circulation is rotated to main shaft 20 does work, and thus can make under the mutual cooperation of four driver elements, the present invention is gone round and begun again Rotation, so as to realize in the case of less without other power or other power, main shaft 20 is constantly rotated, so that externally Rotational power is exported, therefore, the present invention can reduce using coal, gasoline, the consumption of natural gas equal energy source, and will not be to big Discharge harmful in compression ring border, reduces environmental pollution.

It according to above-mentioned principle, can also make what all size was not waited, for sight, be adapted to various occasion handicrafts, The value of the present invention is set to play maximum economic benefit.
