Figure 10 to Figure 14 is referred to, it is signal of the present invention in five kinds of different working conditions：

Wherein, Figure 10 is to initially enter working state schematic representation, Figure 11 be at driver element in working order in, Tu12Wei Deactivate in state, during Figure 13 is to return original state, Figure 14 revert to original state and repeat to enter work for driver element Make state intention, the cam 103 of four driver elements, in the gradual staggered installation of an angle of 90 degrees, makes four drivings in frame The swing span 10 of unit is in from the side as shown in figure 15, when being in Figure 12 states with the first driver element, the second driver element Figure 11 states are then in, the 3rd driver element is in Figure 10 states, and the 4th driver element is then in Figure 13 state positions and Figure 14 Between state position.And the driver element in Figure 11 states is in in the middle of main axis acting, so that the present invention is complete There is initial launch function into after installation.

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, the operation principle of the present invention is illustrated with Figure 10 state-drivens unit：

Diameter ratio with the length of swing arm 11 and drive sprocket 21 is as 30: 1, and 40 centimetres of the diameter of drive sprocket 21 is main As a example by the gearratio 1: 2 of movable sprocket 21 and sprocket wheel 105, during original state, driver element is in state as shown in Figure 10, this When, second chimb 1072 of cam 107 tackles pulley 103 and separated state, applies in the right-hand member only drawstring 40 of swing span 10 Plus suspension 50 and rotating turret 101, weight produced by pressure wheel 102.The gravity of the left side balancing weight 13 of swing span 10 is more than Drawstring 40 to the pulling force of the right-hand member of swing span 10 and the left side of swing span 10 toward drive shaft during lower swing 20 rotate when it is required Weight, therefore, the left end of swing span 10 under the Action of Gravity Field of balancing weight 13 to lower swing so that swing arm 11 drive annulus 34 counterclockwises, so as to band pawl 32 promotes the counterclockwise of ratchet 31, because ratchet 31 is synchronous connection with main shaft 20 , ratchet 31 drives the counterclockwise of main shaft 20 again, so that main shaft 20 externally exports rotational power, when driver element operation During to Figure 11 states, swing span 10 has swung 45 °, and swing span 10 also drive shaft 20 have rotated 45 °, meanwhile, because actively Sprocket wheel 21 is 1: 2 with the gearratio of sprocket wheel 105, that is, drive sprocket 21 rotates a circle and can enclose with the rotation of movable sprocket 105 two so that Main shaft 20 have rotated counterclockwise 90 ° by drive sprocket 21, chain 104, sprocket wheel 105 and the driving cam 107 of rotating shaft 106, now, The driver element for being in rear stage initially enters working condition, meanwhile, the driver element of previous stage is then deactivated state.Drive Unit continues to be run from Figure 11 to Figure 12 states, and during from Figure 11 to Figure 12, this driver element then drives list with latter Unit does work to main shaft 20 jointly, (being to rotate to do work to main shaft 20 jointly with previous stage driver element from Figure 10 to Figure 11), in pendulum When Figure 12 states are swung under the left side of moving frame 10, the whole process of swing span 10 has swung 90 °, meanwhile, swing span 10 is also by ratchet machine The drive shaft 20 of structure 30 have rotated 90 °, and cam 107 have rotated 180 °, and the first chimb 1071 of cam 107 is contacted with pulley 103 And pulley 103 is pressed downward, now, driver element stops rotating acting to main shaft 20, and main shaft 20 is in driver element below Continue to rotate counterclockwise under driving.At the same time, due to when the left side of swing span 10 is toward lower swing right-hand member raise, from there through drawing Rope 40 drives suspension 50 to move up, simultaneously as the amplitude of fluctuation of swing span 10 is suspension 50 moves up and down amplitude Twice, when the right of swing span 10 is raised, the distance between drawstring 40 is from the junction of swing arm 11 to roller 52 can incrementally increase, Then progressively shorten from roller 52 to the distance of frame fixing end, thus drive roller 52 to rotate clockwise.Due to wheel shaft 51, taper Screw thread wheel 53 and roller 52 are synchronous interaction relations so that roller 52, wheel shaft 51 and the synchronous axial system of tapered thread wheel 53, and with Rotation to move up and along the motion of the length direction of wheel shaft 51.So that the contact between tapered thread wheel 53 and pressure wheel 102 Point has rotated to lower from highest point.

So far, driver element will continue to rotate main shaft 20 acting it is necessary to revert to initial position, now it is necessary to pressure Power source is transferred to the right-hand member of swing span 10 by the pressure that power component 100 is produced by suspension 50 and drawstring 40, so that swing span 10 right-hand members to lower swing left end is raised, therefore, in the work more than, cam 107 after rotating 180 °, open by the second chimb 1072 Beginning separates with pulley 103, and the first chimb 1071 contacts with pulley 103 and pulley 103 is pressed downward so that the right side of rotating turret 101 End moves up in the presence of pressure wheel 102, so that cylinder 108 produces compression to stage clip 110, while stage clip 110 also produce a reverse pressure to cylinder 108, so that pressure assembly 100 has a downward pressure to pass through pressure Wheel 102 is applied on suspension 50, and power source is delivered to Jing drawstrings 40 right-hand member of swing span 10.Because pressure wheel 102 is pivot The middle part of rotating turret 101 is connected on, that is, the left end pulley 103 of rotating turret 101 is between the right-hand member pivoting point of rotating turret 101 Portion, therefore, now pressure assembly 100 is applied with the pressure produced by twice stage clip 110 to suspension 50, that is to say, that in pressure When the pressure that spring 110 is produced is G, the pressure that now suspension 50 is born is two G.Now include the pressure wheel of rotating turret 101 Two drawstrings 40 are applied with a downward pulling force more than a G by 102 weight for applying in the right and left of roller 52.While two Drawstring 40 also has a reversal interlocking relay upwards, because right section (from roller 52 to frame fixing point) of drawstring 40 is fixed on frame On, thus, two pulling force downwards upwards 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 downward pulling force of right-hand member is matched somebody with somebody greatly The resistance that pouring weight 13 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 produces downward pulling force more than pendulum During the gravity of the left end balancing weight 13 of moving frame 10, swing span 10 has the trend to lower swing, thus, in the left and right two of roller 52 The drawstring 40 on side occurs in that two not reciprocity pulling force upwards, and the right is more than the left side, therefore so that there is one on two rollers 52 Anticlockwise rotation force, so that the rotation of the inverse time of roller 52, and move down in rotation and along the length side of wheel shaft 51 To motion, 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 and wheel shaft 51 And tapered thread wheel 53 is synchronous connection, therefore, tapered thread wheel 53 be also as roller 52 is moved down in rotation, and Rotate move down in thread groove 531 incrementally increase with the contact point of pressure wheel 102, be from the central point of wheel shaft 51 to screw thread The contact point of groove 531 and pressure wheel 102, can incrementally increase with moving down in rotation, and with move down height be it is equal, That is the central point of wheel shaft 51 is moved downwardly how many, while driving tapered thread 53 to make thread groove in rotation is moved down 531 increase how many with the contact point of pressure wheel 102, make rotating turret 101 not move down in the presence of tapered thread wheel 53, First chimb 1071 is maintained at pressed status to pulley 103.Thus, pressure assembly 100 can be made to have a downward pressure all the time It is applied on suspension 50, and power source is delivered to Jing drawstrings 40 right-hand member of swing span 10, makes the right-hand member of swing span 10 with suspention Component 50 simultaneously to lower swing, raise, at the same time, in 10 clockwise oscillation of swing span, due to ratchet mechanism 30 by left end Unidirectional drive performance, the now drive of main shaft 20 ratchet 31 continues to rotate counterclockwise, and then band pawl 32 turns clockwise swing span 10 Dynamic, the front end of ratchet 32 slips over from the back of tooth of ratchet 31, and when driver element is run to Figure 14 states, cam 107 is in main shaft 20 180 ° are rotated by, the first chimb 1071 is separated with pulley 103, the reply pulley 103 of the second chimb 1072 is simultaneously separated State, the left end of rotating turret 101 does not have pressure to act on, and the right-hand member of rotating turret 101 is moved down under the effect of the pressure of stage clip 110, pressure group Part 100, without pressure, only has the suspension 50 and rotating turret of the applying of drawstring 40 to suspension 50 in the right-hand member of swing span 10 101st, the gravity produced by pressure wheel 102, driver element revert to original state and in the Action of Gravity Field lower swing of balancing weight 13 To lower swing, driver element repeats to enter to the rotation acting of main shaft 20 left end of frame 10, repeats the above course of work.

In the course of work more than, when the first chimb 1071 of cam 107 is pressed down to pulley 103 one will be produced A little energy losses, are now accomplished by the driver element (driver element i.e. in Figure 11 states) in rear stage and pay one with merging Fixed energy, logical main shaft 20 drives the first chimb 1071 of the driving cam 107 of drive sprocket 21 to be pressed downward pulley 103.Due to, The length of swing arm 11 is 30 times of the diameter of drive sprocket 21, and the diameter of drive sprocket 21 is 40 centimetres, because drive sprocket 21 with The rotation ratio of sprocket wheel 105 is 1: 2, and thus the diameter of sprocket wheel 105 is 20 centimetres so that the radius of sprocket wheel 105 and cam 107 are from turning The central point of axle 106 to the first chimb 1071 height ratio between 2: 1 to 4: 1, because the middle part of swing span 10 is articulated in On main shaft 20, that is to say, that the stress point at the two ends of swing span 10 or so is to the equal length of main shaft 20.According to Du's rod principle, The gravity applied in the right-hand member of swing span 10 is more than the gravity of the left end balancing weight 13 of swing span 10, and the right-hand member of swing span 10 can be downwards Pendulum.Therefore stage clip 110 produces weight of the downward pressure than balancing weight 13 (including the pressure wheel 102 of rotating turret 101 and suspention group The weight that part 50 applies) many 10%-80% weight, also, pressure wheel 102 is articulated in the middle part of rotating turret 101 so that It is equal that the resistance that cam 107 is subject to produces downward pressure with stage clip 110, that is to say, that in the first chimb of cam 107 1071 pairs of pulleys 103 have one to prevent the counterclockwise of cam 107 with the pressure that stage clip 110 is produced when being pressed downward, and this hinders Power is slightly less than drawstring 40 and is applied to the downward pulling force on the right of swing span 10 (resistance that cam is subject to does not include rotating turret, pressure Wheel 102, the weight of suspension 50), therefore the driver element of rear stage (driver element i.e. in Figure 11 states) will be in Pay certain energy to go to overcome this resistance, according to above-mentioned parameter, sprocket wheel 105 radius with cam 107 from the center of rotating shaft 107 Height ratio to the first chimb 1071 between 2: 1 to 4: 1, therefore, when the resistance that cam 107 is subject to is transferred to drive sprocket 21 The namely 50%-90% of the weight of balancing weight 13, that is to say, that the gravity for having a balancing weight 13 on drive sprocket 21 is prevented The counterclockwise of sprocket wheel 105, because the length of swing arm 11 is 30 times of the diameter of drive sprocket 21, therefore, as long as rear stage is (i.e. Driver element in Figure 11 states) driver element balancing weight 13 pay the weight of 5%-10% by overcome cam 107 to produce Resistance.And balancing weight 13 is removed to need to carry and also have 70%- outside the above-mentioned energy of arch and the mechanical friction of itself loss 90% or so weight is used to rotate externally output power by drive shaft 20.

Thus, under the cooperating of four driver elements, main shaft 20 is able to lasting rotation and externally exports power.

The main shaft 20 of four driver elements of the invention is arranged in order and synchronously joins along the length direction (i.e. X to) of frame Connect, the main shaft 20 actually may be configured as one, and four driver elements share the main shaft 20.

Fig. 8 is referred to, as further improvement, except aforementioned four driver element, an idle driving can be also set Unit, when aforementioned four driver element one of them break down need repairing when, suspend the driver element, and start described Idle driver element just can, thus can make to be not required to overall shutdown, you can carry out maintenance maintenance.Concrete implementation mode is：It is described 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 sprocket wheel In 105 interior octet 1051, meanwhile, the top edge of octet 1051 offers screw hole (not indicating in figure) in sprocket wheel 105, There is a screw 1052 in screw hole, screw 1052 is connected on the octahedral one of face of the rotating shaft 106, so that rotating shaft 106 realize fixed relationship with sprocket wheel 105；When have driver element need maintenance maintenance when, unclamp screw 1052, sprocket wheel 105 from The octahedron of rotating shaft 106 is exited, and then adjusts the rotating shaft 106 of idle driver element so as to the angle of cam 107 and swing span 10 Angle be consistent with the angle of driver element suspended, then sprocket wheel 105 is reinstalled into the octahedron of rotating shaft 106 by screw 1052 tighten fixation, and the locating dowel 223 on the clutch plate 22 of idle driver element is pushed into the location hole 211 of drive sprocket 21, The idle driver element can be started, then will need to overhaul the clutch plate 22 of driver element, logical pull bar 24 pushes away clutch plate Drive sprocket 21, makes locating dowel 223 exit from location hole 211, just can complete to suspend driver element to be repaired, can make again after maintenance For new idle driver element, for replacing new failure driver element.

In sum, the present invention passes through ratchet mechanism 30 by power using the gravity that balancing weight 13 is produced to the left end of swing span 10 Square is put on main shaft 20, is that main shaft 20 provides the power source for rotating, meanwhile, the pressure produced using pressure assembly 100 is applied to Power source is applied to the Jing drawstrings 40 of suspension 50 right-hand member of swing span 10 in the way of transmitting, and makes the right-hand member of swing span 10 to the bottom Dynamic, left end is raised, and makes balancing weight 13 revert to initial position, and repetitive cycling is rotated to main shaft 20 and done work, thus, can make at four Under the cooperating of driver element, the present invention is able to the rotation for going round and beginning again, so as to realize without other power or other power In the case of less, main shaft 20 is set constantly to rotate, so as to externally export rotational power, therefore, the present invention can reduce utilization Coal, gasoline, the consumption of natural gas equal energy source, and environmental pollution will not be reduced to discharge harmful in atmospheric environment.

It will be apparent to those skilled in the art that technical scheme that can be as described above and design, make other various It is corresponding to change and deformation, and all these change and deformation should all belong to the protection model of the claims in the present invention Enclose.
