Figure 12 to Figure 16 is referred to, it is five kinds of schematic diagrames of different working condition of every group of drive mechanism of the invention：

Wherein, Figure 12 is that this group of drive mechanism the right driver element initially enters working condition, and left side driver element is exited Working state schematic representation, Figure 13 be at the driver element of this group of drive mechanism the right in working order in, left side driver element is returned Original operating state schematic diagram, Figure 14 is that this group of drive mechanism the right driver element completes a course of work backed off after random work shape State, left side driver element enters working state schematic representation, and Figure 15 is that the right driver element returns original operating state, and the left side drives The in running order schematic diagram of unit, Figure 16 is again introduced into work for this group of drive mechanism the right driver element revert to original state Make state, left side driver element exits working state schematic representation, and two groups of cams of drive mechanism 74 are in the staggered peace of an angle of 90 degrees Dress, when one of which drive mechanism is in Figure 12 states, another group of drive mechanism is then in the state of Figure 13, and is caused Another group of the right driver element of drive mechanism is in and main shaft 20 is rotated in the middle of acting, so that after the present invention completes to install i.e. With initial operation function.

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

Wherein, operation principle of the invention is illustrated with the drive mechanism in Figure 12 states：

It is rotated by 360 ° with a driver element haulage drum 10 of work, cam 107 is rotated as a example by 180 °, during original state, Main shaft 20 drives drive sprocket 21 to rotate counterclockwise, because sprocket wheel 105 and drive sprocket 21 couple through chain 104 is synchronous, from And cause that sprocket wheel 105 is rotated counterclockwise by rotating shaft 106 with moving cam 107, makes the first chimb 1071 of cam 107 and pulley 103 contact and the left end to rotating turret 101 press down so that the right-hand member in the presence of pressure wheel 102 of rotating turret 101 is moved upwards It is dynamic, compression is produced to stage clip 110 when moving up two cylinders 108, so that 110 pairs of two cylinders 108 of stage clip have one Individual reverse pressure, so that rotating turret 101 has a downward pressure to be applied on suspension 50 through pressure wheel 102, The right-hand member of roller 10 is transferred to through drawstring 40, to there is roller 10 to apply the torque for rotating clockwise, meanwhile, drawstring 40 also has One upward reversal interlocking relay, because right section (being the fixing point from wheel shaft 51 to frame) of drawstring 40 is fixed in frame, Thus, two pulling force upward downwards are equal.At left section (from wheel shaft 51 to one section of roller 10) of drawstring 40, due to being It is connected on roller 10, and roller 10 is not fixed.As long as the power for rotating clockwise that the right-hand member of roller 10 applies Square, the torque of the counterclockwise applied to roller 10 more than the left end balancing weight 12 of roller 10, and roller 10 is rotated clockwise When by the first ratchet mechanism 30 and transmission mechanism 90, the counterclockwise of drive shaft 20 externally export power required for energy It is lost with mechanical friction, roller 10 can be rotated clockwise.Produced due to pressure assembly 100 pressure (including rotating turret 101, The gravity that pressure wheel 102 and suspension 50 apply) it is greater than the weight and the counterclockwise of drive shaft 20 of balancing weight 12 What energy and mechanical friction externally required for output power was lost, therefore, the right-hand member of roller 10 has one under the pulling of drawstring 40 The individual trend for rotating clockwise, so that the drawstring 40 in the right and left of wheel shaft 51 occurs in that two not reciprocity pull up Power, the right is more than the left side so that have an anticlockwise revolving force on wheel shaft 51, so that the counterclockwise of wheel shaft 51, And moved down in rotation and moved along the length direction of wheel shaft 51, while drive roller 10 to rotate clockwise, so that Lifting rope 11 winds to roller 10, so as to drive balancing weight 12 to move up.In the process, due to wheel shaft 51 and tapered thread wheel 52 is synchronous connection.Therefore, tapered thread wheel 52 is also as wheel shaft 51 is moved down in rotation, and under rotation Thread groove 521 is incrementally increased with the contact point of pressure wheel 102 in shifting.It is from the central point of wheel shaft 51 to thread groove 521 With the contact point of pressure wheel 102, can be incrementally increased in rotation with moving down, and be equal with height is moved down.Namely Say, the central point of wheel shaft 51 is moved downwardly how many, while drive tapered thread wheel 52 makes thread groove 521 in rotation is moved down Increase how many with the contact point of pressure wheel 102, rotating turret 101 is not moved down in the presence of tapered thread wheel 52, make One chimb 1071 keeps pressed status to pulley 103.Thus, may be such that pressure assembly 100 (rotating turret 101) have all the time one to Under pressure be applied on suspension 50, and power source is delivered to the right-hand member of roller 10 through drawstring 40, make roller 10 clockwise Rotate, when driver element is run to Figure 13 states, the pressure that pressure assembly 100 is produced is led by suspension 50 and drawstring 40 Draw roller 10 and rotated clockwise 180 °, roller 10 is also by the first ratchet mechanism 30 and the inverse time of 90 drive shaft of transmission mechanism 20 Pin have rotated 180 °, so that main shaft 20 externally exports power.Main shaft 20 is by drive sprocket 21, chain 104, sprocket wheel simultaneously 105 and 90 ° of 106 driving cam of rotating shaft 107 rotate counterclockwise.Now, another group of drive mechanism has a driver element to enter Working condition, one is exited working condition.Driver element continues to be run from Figure 13 to Figure 14 states, when driver element service chart 14 The pressure that pressure assembly 100 is produced during state has rotated clockwise 360 ° by suspension 50 and the haulage drum 10 of drawstring 40, Roller 10 has rotated counterclockwise 360 ° also by ratchet mechanism 30 and the drive shaft 20 of transmission mechanism 90, and cam 107 revolves counterclockwise 180 ° are turned, now, the first

suspension 50, there was only pressure frame 101 on suspension 50 And the gravity of pressure wheel 102, so that the right-hand member in roller 10 only has suspension 50, pressure frame 101 and pressure wheel 102 to lead to The gravity of the applying of drawstring 40 is crossed, so far, the right driver element stops that the rotation of main shaft 20 is done work and entered to return initial shape program. Left side driver element enters working condition simultaneously, the counterclockwise and by second under the Action of Gravity Field of balancing weight 12 of roller 10 Rotatory force is put on main shaft 20 by ratchet mechanism, and power source is provided for main shaft 20 is rotated, in 10 counterclockwise of roller, two drawstrings 40 wind to roller 10, so as to tighten up two drawstrings 40, make the contraction in length of drawstring 40, thus drive the up time of suspension 50 to rotate, And moved up in rotation and moved along the length direction of wheel shaft 51, so as to drive the right driver element initial to returning State motion, when driver element runs to Figure 15 states, balancing weight 12 is through the counterclockwise of 11 haulage drum of lifting rope 10 180 °, roller 10 has rotated counterclockwise 180 ° by the second ratchet mechanism drive shaft 20, so that main shaft 20 is externally exported Power.Main shaft 20 passes through drive sprocket 21, chain 104, sprocket wheel 105 and the rotate counterclockwise of 106 driving cam of rotating shaft 107 simultaneously 90°.Now, another group of drive mechanism has a driver element to enter working condition, and one is exited working condition.Driver element after Continuous to be run from Figure 15 to Figure 16 states, when driver element 16 state of service chart, balancing weight 12 is inverse through the haulage drum 10 of lifting rope 11 Hour hands have rotated 360 °, and roller 10 has rotated counterclockwise 360 ° by the second ratchet mechanism drive shaft 20, and cam 107 is counterclockwise Have rotated 180 °.So far, left side driver element stops that the rotation of main shaft 20 is done work and entered to return original state, now, second Chimb 1072 is separated with pulley 103, the first chimb 1071 contacted with pulley 103 and in rotation to the left end of rotating turret 101 down Pressure, so that right driver element is again introduced into working condition rotates acting to main shaft 20, repeats said process.

When the first chimb 1071 of every group of drive mechanism contacts with pulley 103 and the left end of rotating turret 101 is pressed down, need another One group of drive mechanism assists to pay certain energy with merging, and could enter normal repetitive cycling working condition to 20 turns of main shaft Dynamic acting.

Thus, in the case where two groups of the four of drive mechanism driver elements cooperate, main shaft 20 is able to lasting turning to the present invention Move and externally export power.
