far, left side driver element completes the process that acting is once rotated to main shaft 20, and the left side drives Unit stops the rotation of main shaft 20 is done work and entered to return original state program.The right driver element enters working condition pair simultaneously Main shaft 20 rotates acting, when the first chimb 1071 is contacted with pulley 103 and 101 left end of rotating turret is pressed down in rotation, So that the right-hand member in the presence of pressure wheel 102 of rotating turret 101 is moved up, move up two cylinders 108 and stage clip 110 is produced Compression so that 110 pairs of two cylinders 108 of stage clip have a reverse pressure so that rotating turret 101 have one to Under pressure Jing pressure wheels 102 be applied on suspension 50, make drawstring 40 have a downward pulling force to be transmitted to swing span 10 Right-hand member, to swing span 10 apply a clockwise oscillation power source.Meanwhile, drawstring 40 also has a reversal interlocking relay upwards, As right section (being the fixing point from wheel shaft 51 to frame) of drawstring 40 is fixed in frame, thus, two downwards upwards Pulling force is equal.At left section (from wheel shaft 51 to a section of 10 right-hand member of swing span) of drawstring 40, due to being to be connected to swing span On 10, and swing span 10 is not fixed.As long as the torque of the clockwise oscillation that 10 right-hand member of swing span applies, is more than The torque of the counter-clockwise swing that 10 left end balancing weight 13 of swing span applies to swing span 10, and during 10 clockwise oscillation of swing span By transmission mechanism 90 and the first ratchet mechanism 30,20 counterclockwise of drive shaft externally export energy required for power and Mechanical friction is lost, and swing span 10 can clockwise oscillation.Due to pressure assembly 100 produce pressure (include rotating turret 101, The gravity that pressure wheel 102 and suspension 50 apply) it is greater than 20 counterclockwise of weight and drive shaft of balancing weight 13 What energy and mechanical friction externally required for output power was lost, therefore, 10 right-hand member of swing span has under the pulling of drawstring 40 The trend of one clockwise oscillation so that the right and left of wheel shaft 51 drawstring 40 occur in that two it is not reciprocity upwards Pulling force, the right are more than the left side so that have an anticlockwise revolving force on wheel shaft 51, so that wheel shaft 51 rotates counterclockwise, And move down in rotation and move along 51 length direction of wheel shaft, while driving 10 clockwise oscillation of swing span, thus make Obtain 10 left end of swing span to raise, so as to drive balancing weight 13 to move up.Thus left side driver element is driven to recurrence initial shape State is moved, in the process, as wheel shaft 51 and tapered thread wheel 52 are synchronous connections.Therefore, tapered thread wheel 52 is also As wheel shaft 51 is moved down in rotation, and rotate move down in thread groove 521 and pressure wheel 102 contact point by Step increase.It is the contact point from the central point of wheel shaft 51 to thread groove 521 with pressure wheel 102, can rotating with moving down In incrementally increase, and be equal with height is moved down.That is, the central point of wheel shaft 51 is moved downwardly how many, while Drive tapered thread wheel 52 to make in rotation is moved down thread groove 521 increases how many with 102 contact point of pressure wheel, make rotating turret 101 do not move down in the presence of tapered thread wheel 52, make the first chimb 1071 keep pressed status to pulley 103.Thus, Pressure assembly 100 (rotating turret 101) can be caused to have a downward pressure to be applied on suspension 50 all the time, and Jing drawstrings 40 Power source is delivered to into the right-hand member of swing span 10,10 clockwise oscillation of swing span is made, when driver element is run to Figure 13 states, pressure The pressure that power component 100 is produced passes through suspension 50 and drawstring 40 draws 45 ° of 10 clockwise oscillation of swing span, while in pendulum During 10 clockwise oscillation of moving frame, the second sprocket wheel 15 is driven to rotate clockwise by axle sleeve 14, due to the second sprocket wheel 15 and driver Structure 90 is synchronous to be coupled, and transmission mechanism 90 is again with the first ratchet mechanism 30 synchronous to be coupled so that 10 clockwise oscillation of swing span Torque drive shaft 20 under the transmission of said mechanism has rotated counterclockwise 45 °, so that main shaft 20 externally exports power.Together When, main shaft 20 drives the first sprocket wheel 105 to rotate counterclockwise by 21 the first chains of Jing of drive sprocket 104, so as to pass through rotating shaft 106 90 ° of driving cam 107 rotate counterclockwise.Now, second group of drive mechanism has a driver element to enter working condition, one Deactivate state.Driver element continues to run from Figure 13 to Figure 14 states, when driver element runs to Figure 14 states, pressure The pressure that component 100 is produced passes through suspension 50 and drawstring 40 draws 90 ° of 10 clockwise oscillation of swing span, swing span 10 90 ° are rotated counterclockwise by transmission mechanism 90 and 30 drive shaft 20 of ratchet mechanism, 180 ° of 107 rotate counterclockwise of cam, Now the first chimb 1071 of cam 107 is separated with pulley 103, and the second chimb 1072 tackles pulley 103 separated state, pressure Power component 100 is applied to the pressure releases on suspension 50, there was only pressure frame 101 and pressure wheel 102 on suspension 50 Gravity so that swing span 10 right-hand member only have suspension 50, pressure frame 101 and pressure wheel 102 pass through drawstring 40 The gravity of applying, so far the right driver element complete once to main shaft 20 rotate acting process, the right driver element stop it is right Main shaft 20 is rotated to do work and enter and returns initial shape program.Swing span 10 is put under the Action of Gravity Field of balancing weight 13 counterclockwise simultaneously It is dynamic, so that left side driver element is again introduced into working condition rotates acting to main shaft 20, repeat said process.

In the course of work more than, when the first chimb 1071 and the pulley 103 of the cam 107 for having one group of drive mechanism connect When the tactile left end to rotating turret 101 is pressed down, it is necessary to which another group of drive mechanism assists to pay certain energy with merging, drives Mechanism could enter repetitive cycling working condition and rotate acting to main shaft 20.

Thus, under the cooperating of four driver elements of two groups of drive mechanisms, main shaft 20 is able to lasting rotation simultaneously Power is exported externally.

The main shaft 20 of two groups of drive mechanisms of the invention is arranged in order and is synchronously joined along the length direction (i.e. X to) of frame Connect, the main shaft 20 actually may be configured as one, two groups of drive mechanisms share the main shaft 20.

Refer to Fig. 8, as further improvement, in addition to two groups of above-mentioned drive mechanisms, can also arrange one group it is idle Drive mechanism, when the one of which of above-mentioned two groups of drive mechanisms breaks down to need repairing, suspends this group of drive mechanism, and opens Move the idle drive mechanism just can, thus can make to be not required to overall shutdown, you can carry out maintenance maintenance, concrete implementation mode It is：First sprocket wheel 105 is provided with interior octet 1051, and the end of rotating shaft 106 is set to octahedron, and the octahedron of rotating shaft 106 Can be inserted in the interior octet 1051 of the first sprocket wheel 105, meanwhile, 1051 top edge of octet is opened up in the first sprocket wheel 105 Have screw hole (not indicating in figure), in screw hole, have a screw 1052, screw 1052 arrive in the rotating shaft 106 it is octahedral its In on a face so that rotating shaft 106 and the first sprocket wheel 105 realize fixed relationship；When there is driver element to need maintenance maintenance, Screw 1052 is unclamped, the first sprocket wheel 105 is exited from the octahedron of rotating shaft 106, then adjust the rotating shaft of idle drive mechanism 106 so as to which phase place of the angle of cam 107 with the angle of swing span 10 with the drive mechanism suspended is consistent, then will First sprocket wheel 105 reinstalls 106 octahedron of rotating shaft and screw 1052 is tightened fixation, by determining on the clutch plate 22 of idle drive mechanism Position post 223 pushes the location hole 211 of drive sprocket 21, you can start the idle driver element, then will need to overhaul driving machine Clutch plate is pushed away drive sprocket 21 by the clutch plate 22 of structure, logical pull bar 24, locating dowel 223 is exited from location hole 211, just may be used Complete to suspend drive mechanism to be repaired, but also as new idle drive mechanism after maintenance, for replacing new failure drive mechanism.

In sum, gravity of the present invention using left side driver element balancing weight 13 to the applying of 10 left end of swing span, makes pendulum 10 left end of moving frame is put on turning moment on main shaft 20 toward lower swing by the second ratchet mechanism 80, is that the offer of main shaft 20 turns Dynamic power source, meanwhile, the pressure produced using the right driver element pressure assembly 100 be applied to 50 Jing drawstrings 40 of suspension with Power source is applied to the mode of transmission the right-hand member of swing span 10, makes the right-hand member of swing span 10 to lower swing, then by transmission mechanism 90 and first ratchet mechanism 30 power source is put on into main shaft 20 so that left and right two driver elements dislocation of group drive mechanism is right Main shaft 20 rotates acting, thus, can make in the case where four driver elements of two groups of drive mechanisms cooperate, the present invention be able to week and The rotation for renewing, so as to realize, in the case of less without other power or other power, making main shaft 20 constantly rotate externally Output rotational power, therefore, the present invention can reduce using coal, gasoline, natural gas equal energy source consumption, and will not be to big Discharge harmful in compression ring border, reduces environmental pollution.
