source is put on into main shaft 20 through ratchet mechanism 30.Work as cam After 107 rotation 180 degrees, the first chimb 1071 is separated with pulley 103, the second chimb 1072 reply pulley 103 and separated state, The pressure releases that pressure assembly 100 applies to suspension 50.So that Action of Gravity Field subinverse of the roller 10 in balancing weight 12 Hour hands are rotated, and drawstring 40 is wound to roller 10, thus drive suspension 50 to rotate clockwise, and moved up in rotation And along the length direction motion of wheel shaft 51, so that Action of Gravity Field Regression initial shape of the driver element in balancing weight 12 State.

Please referring particularly to Fig. 6, the position-limit mechanism 80 is fixedly arranged in frame, and the position-limit mechanism 80 is by being fixed in frame Four bumping posts are constituted, four one group two-by-two of bumping posts, external peripheral surface of two groups of bumping post difference blockings at the two ends of wheel shaft 51.Every group of gear The top of post is provided with a locating part, and the position-limit mechanism 80 is used to limit wheel shaft 51 only in above-below direction and along the length side of wheel shaft 51 To movement, and the peak for moving up can only on move on to locating part, specifically, in 10 counterclockwise of roller, due to The unidirectional drive performance of ratchet mechanism 30, with main shaft 20 without interaction relation, driver element is in original state is returned for roller 10 It is difficult to keep synchronous with main shaft 20, that is to say, that in main shaft 20 by drive sprocket 21 through the band of 104 sprocket wheel of chain, 105 rotating shaft 106 When first chimb 1071 of moving cam 107 is contacted with pulley 103, roller 10 drives suspension 50 to be difficult to keep synchronously to be returned to The position of setting, it is excessively slow too fast all uncoordinated to mechanical movement, shutdown is will ultimately result in, therefore, the speed that the inverse time of roller 10 rotates Degree will be faster than the speed that main shaft 20 is rotated clockwise, and driver element is revert to original state in advance, upward in suspension 50 Moving to locating part can not be moved up again, and driver element is waited in resting on setting position.

Figure 11 to Figure 15 is referred to, it is the present invention in five kinds of schematic diagrames of different working condition：

Wherein, Figure 11 is to initially enter working state schematic representation, Figure 12 be at driver element in working order in, Tu13Wei Exit in working condition, Figure 14 is in recurrence original state, Figure 15 repeats to enter work for driver element revert to original state View, four cams of driver element 107 are in the staggered installation of an angle of 90 degrees.So that four driver elements complete to install Afterwards, 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 Figure 15 state positions, and so that in Figure 12 states Driver element is in and main shaft 20 is rotated in the middle of acting.So that the present invention has initial launch function after completing to install.

When running well, the locating dowel 223 of clutch plate 22 is inserted in the location hole 211 of drive sprocket 21 present invention, Make main shaft 20 with the relation that drive sprocket 21 is synchronous connection；

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

It is rotated by 360 ° with a driver element haulage drum 10 of work, diameter and the diameter proportion of drive sprocket 21 of roller 10 It is 10: 1, as a example by 21 a diameter of 20 centimetres of drive sprocket, during original state, main shaft 20 drives drive sprocket 21 to rotate clockwise, Because sprocket wheel 105 and drive sprocket 21 are through the synchronous connection of chain 104 so that sprocket wheel 105 by rotating shaft 106 with moving cam 107 rotate clockwise, and make that the first chimb 1071 of cam 107 is contacted with pulley 103 and the left end to rotating turret 101 is pressed down, So that the right-hand member in the presence of pressure wheel 102 of rotating turret 101 is moved up, stage clip 110 is produced when moving up two cylinders 108 Raw compression, so that 110 pairs of two cylinders 108 of stage clip have a reverse pressure, so that rotating turret 101 has one Downward pressure is applied on suspension 50 through pressure wheel 102, so that drawstring 40 has a downward pulling force, meanwhile, Drawstring 40 also has a upward reversal interlocking relay, because right section (being the fixing point from roller 52 to frame) of drawstring 40 is fixed In frame, thus, two pulling force upward downwards are equal.At left section of drawstring 40 (from roller 52 to the one of roller 10 Section), due to being connected on roller 10, and roller 10 is not fixed, as long as the up time that the right-hand member of roller 10 applies The torque of the torque more than the counterclockwise that the left end balancing weight 12 of roller 10 applies to roller 10 of pin rotation, and roller 10 is suitable Drive shaft 20 rotates energy externally required for output power and mechanical friction loss when hour hands are rotated, and roller 10 can up time Pin is rotated.Pressure (including the weight that rotating turret 101, pressure wheel 102 and suspension 50 apply produced due to pressure assembly 100 Power) it is greater than the weight of balancing weight 12 and drive shaft 20 rotates clockwise energy and machinery externally required for output power Frictional dissipation, therefore, the right-hand member of roller 10 has the trend for rotating clockwise under the pulling of drawstring 40, so that in rolling The drawstring 40 of the right and left of wheel 52 occurs in that two not reciprocity upward pulling force, and the right is more than the left side so that on roller 52 There is an anticlockwise revolving force, so that the counterclockwise of roller 52, and moved down in rotation and grown along wheel shaft 51 The motion of degree direction, so that drive roller 10 to rotate clockwise, so that lifting rope 11 winds to roller 10, so as to drive balancing weight 12 move up.In the process, because roller 52, wheel shaft 51 and tapered thread wheel 53 are synchronous connections.Therefore, taper spiral shell Line wheel 53 be also as wheel shaft 51 and roller 52 are moved down in rotation, and in rotation is moved down thread groove 531 with The contact point of pressure wheel 102 is incrementally increased.It is from the central point of wheel shaft 51 to the contact with pressure wheel 102 of thread groove 531 Point, can incrementally increase, and be equal with height is moved down with moving down in rotation.That is, the central point of wheel shaft 51 It is moved downwardly how many, while drive tapered thread wheel 53 makes thread groove 531 and the contact point of pressure wheel 102 in rotation is moved down Increase how many, rotating turret 101 is not moved down in the presence of tapered thread wheel 53, make the first chimb 1071 to pulley 103 keep pressed status.Thus, may be such that pressure assembly 100 (rotating turret 101) has a downward pressure to be applied to all the time outstanding Hang on component 50, and power source is delivered to the right-hand member of roller 10 through drawstring 40, rotate clockwise roller 10, when driver element fortune When row is to Figure 12 states, the pressure that pressure assembly 100 is produced is turned clockwise by suspension 50 and the haulage drum 10 of drawstring 40 180 ° are moved, roller 10 has rotated clockwise 180 ° also by the drive shaft 20 of ratchet mechanism 30, so that main shaft 20 is external Output power.Main shaft 20 passes through drive sprocket 21, chain 104, sprocket wheel 105 and the dextrorotation of 106 driving cam of rotating shaft 107 simultaneously 90 ° are turned.Now, the driver element for being in rear stage initially enters working condition.Meanwhile, the driver element of previous stage is then exited Working condition.Driver element continues to be run from Figure 12 to Figure 13 states, and during the state from Figure 12 to Figure 13, this drives single It is first then common with rear stage driver element to rotate acting to main shaft 20 (be jointly right with previous stage driver element from Figure 11 to Figure 12 Main shaft 20 rotates acting), when driver element runs to Figure 13 states, the whole haulage drum 10 of drawstring 40 is rotated clockwise 360 °, while roller 10 is also to have turned clockwise 360 ° by the drive shaft 20 of ratchet mechanism 30, cam 107 is rotated clockwise 180 °.Now, the first chimb 1071 is separated with pulley 103, the second chimb 1072 reply pulley 103 and 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 The gravity of applying, so far, driver element stops rotating main shaft 20 acting, and driver element is completed once to rotate main shaft 20 and done The process of work(.Now, the counterclockwise under the Action of Gravity Field of balancing weight 12 of roller 10, makes two drawstrings 40 be wound to roller 10, So as to drive suspension 50 to rotate clockwise and move up in rotation and along the motion of the length direction of wheel shaft 51, work as fortune Row to driver element during Figure 15 states revert to original state, because the speed of the counterclockwise of roller 10 turns slightly larger than clockwise Dynamic speed, cam 107 now is also not rotated to the first chimb 1071 and is contacted with pulley 103, therefore driver element is stopped Waited in Figure 15 states.Due to the unidirectional drive performance of ratchet mechanism 30 in reseting procedure, depart to drive with main shaft 20 and close System, drives ratchet 31 to continue to rotate clockwise under the driving of the driver element below of main shaft 20.Roller 10 then drive annulus 34 and The counterclockwise of ratchet 32, the front end of ratchet 32 slips over from the back of tooth of ratchet 31.When cam 107 turns to the first chimb 1071 and slides Take turns 103 contacts and the left end to rotating turret 101 is stayed when pressing, driver element is to be again introduced into working condition to do the rotation of main shaft 20 Work(, repeats said process.

When the first chimb 1071 of each driver element contacts with pulley 103 and the left end of rotating turret 101 is pressed down, now Need the driver element of previous stage (driver element in Figure 12 states) to assist and pay certain energy, circulation could be entered Working condition is rotated to main shaft 20 and done work.Because drive sprocket 21 rotates 360 degree, sprocket wheel 105 just rotates 180 degree, drive sprocket 21 diameter is 20 centimetres so that the diameter of sprocket wheel 105 is 40 centimetres, so that cam 107 is from the center of rotating shaft 106 to The height of one chimb 1071 and the radius scale of sprocket wheel 105 are 1: between 4-1: 8, simultaneously because pressure wheel 102 is pivot joint rotating Middle part between the middle part of frame 101, that is, the left end pulley 103 of rotating turret 101 and right-hand member pivot end so that suspension 50 is received To pressure be the pressure of stage clip 110 twice, that is to say, that when cam 107 is pressed down to the left side of rotating turret 101, the resistance being subject to It is big with the pressure that stage clip 110 is produced extremely equal, and slightly less than drawstring 40 is applied to the pulling force of the right-hand member of roller 10 (because of cam 107 The resistance being subject to does not include the gravity of rotating turret 101, pressure wheel 103 and suspension 50).Hence in so that what cam 107 was subject to When resistance is delivered to drive sprocket 21, the resistance of the 13/100-30/100 of the pressure of stage clip 110 is also equivalent to, due to roller 10 It is 10: 1 with the diameter proportion of drive sprocket 21, according to lever principle, roller 10 is 10 times to the torsion of drive sprocket 21, because This, as long as being driven by energy of the driver element of previous stage (being the driver element in Figure 12 states) with 2%-5% Drive sprocket 21 is rotated clockwise, thus by chain 104 with movable sprocket 105 through rotating shaft 106 with moving cam 107 by rotating turret 101 springs 110 have a reverse pressure, make rotating turret 101 have a downward pressure to be applied to suspention group by pressure wheel 102 On part 50, power source is transferred to the right-hand member of roller 10 through drawstring 40, rotates clockwise roller 10, applied by ratchet mechanism 30 In main shaft 20, power source is provided for main shaft 20 rotates output power.Meanwhile, the driver element is removed to be needed to provide above-mentioned required energy Mechanical friction loss needed for amount and the rotation of itself driver element is outer, and also 90% or so energy is used as externally output power.

Therefore, under four mutual cooperations of driver element, main shaft 20 is able to lasting rotation and externally exports the present invention Power.

Four main shafts of driver element 20 of the invention are arranged in order and synchronously join 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 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, 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, offer screw hole in the outward flange of the interior octet 1051 of sprocket wheel 105 and (do not marked in figure Show), there is a screw 1052 in screw hole, screw 1052 can be arrived on the octahedral one of face of the rotating shaft 106, so that Rotating shaft 106 is set to realize fixed relationship (as shown in Figure 8) with sprocket wheel 105；When there is driver element to need maintenance maintenance, screw is unclamped 1052, sprocket wheel 105 is exited from the octahedron of rotating shaft 106, the rotating shaft 106 of idle driver element is then adjusted, make its cam 107 Angle be consistent with the phase of driver element to be repaired, then sprocket wheel 105 is loaded into the octahedra by screw of rotating shaft 106 1052 tighten fixation, and the locating dowel 223 on the clutch plate 22 of idle driver element is pushed 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 22 From drive sprocket 21, locating dowel 223 is exited from location hole 211, just can complete to suspend driver element to be repaired, again can after maintenance As new idle driver element, for replacing new failure driver element.

In sum, the present invention using pressure assembly 100 produce pressure be applied on suspension 50 through drawstring 40 with The mode of transmission is applied to the right-hand member of roller 10, rotates clockwise roller 10, and main shaft 20 is put on by ratchet mechanism 30, is Main shaft 20 is rotated and provides power source, and the gravity applied to the another side of roller 10 using balancing weight 12 makes driver element revert to initially State repetitive cycling is rotated to main shaft 20 and done work.Thus, can make under four mutual cooperations of driver element, the present invention is able to week And the rotation for renewing, so as to realize in the case of less without other power or other power, main shaft 20 is constantly rotated, and The power that externally output is rotated.Therefore the present invention can reduce the consumption of the energy, and will not be to discharging nuisance in atmospheric environment Matter, reduces environmental pollution.

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.
