Incorporated by reference to refering to Fig. 8, Fig. 9, described top power assembly 70 includes chain 71, drive sprocket 72, cam 74 and being articulated in Power transmission shaft 73 in frame, the both ends of this power transmission shaft 73 synchronize connection drive sprocket 72 and cam 74, and drive sprocket 72 couple by chain 71 is Tong Bu with main shaft 20, and this cam 74 is installed in the other end of power transmission shaft 73, and extends to the second counterweight The bottom (not indicating in figure) of block 63 relative smooth, under cam 74, side sets lubricating oil (not indicating in figure), and this lubricating oil is used In the first chimb 741 and increase lubrication when contacting bottom the second balancing weight 63, reduce frictional force.When drive sprocket 72 is being led Under the drive of axle 20, it is possible to band moving cam 74 rotates, make cam 74 first chimb 741 jack-up the second balancing weight 63, to release pressure Power group 60 is the downward pulling force to applying on the right of swing span 10 by suspension 50 and stay cord 40 so that swing span 10 left end is the Swung downward under the action of gravity of one balancing weight 13, rotates acting to main shaft 20.When the first chimb 741 separates with the second balancing weight After, pressure assembly is pressed in for 60 times on suspension 50 so that the gravity that pressure assembly 60 is downward, can pass through suspension 50 and draw Rope 40 is applied to the right-hand member of swing span 10, makes the right-hand member swung downward of swing span 10, and left end is raised.The most in the present embodiment, Described drive sprocket 21 is 1: 2 with the gear ratio of drive sprocket 72, i.e. drive sprocket 21 rotates a circle, and drive sprocket 72 rotates two In week, thus strap cam 74 rotates two weeks, is provided with the first chimb 741 and the second chimb 742 on cam 74, and the second chimb 742 is high Degree is less than the first chimb 741 height, and the radius of this drive sprocket 72 is more than the radius of cam 74, namely from power transmission shaft 73 center Point arrives the height radius less than drive sprocket 72 of the first chimb 741 of cam 74.

Please referring particularly to Fig. 6, described position-limit mechanism 80 is installed in frame, and this position-limit mechanism 80 is used for limiting 51, wheel shaft Move at above-below direction with along wheel shaft 51 length direction, and the minimum point that wheel shaft 51 moves down, concrete, position-limit mechanism 80 by Four bumping posts composition being fixed in frame, four bumping posts one group two-by-two, the often group bumping post blocking excircle at wheel shaft 51 two ends Surface, is provided with connector in the bottom often organizing grade post, and this setting makes the wheel shaft 51 can only be at above-below direction with along wheel shaft 51 length Direction is moved, and the nadir that wheel shaft 51 moves down can only move down at connector, concrete, clockwise at swing span 10 During rotation, main shaft 20 then rotates counterclockwise, and due to the unidirectional drive performance of ratchet mechanism 30, now, swing span 10 is with main Axle 20 departs from driving relationship, owing to not having interaction relation, is extremely difficult to synchronize with cam 74, also during swing span 10 clockwise oscillation That is, when the first chimb 741 of cam 74 connects the left end of jack-up rotating turret 61 with the second balancing weight 63, swing span 10 is very Being hard to keep and synchronize the position that the bottom is the most set, when crossing slow, driver element will enter duty in advance, will be beyond work time too fast Make scope, thus will appear from four driver elements inharmonious, will eventually shut down, therefore, swing span 10 clockwise oscillation Time speed be greater than the speed that main shaft 20 rotates counterclockwise, make swing span 10 be returned to initial position in advance, make wheel shaft 51 times Move on to no longer stay at connector movement, and swing span 10 rests on setting position etc. and waits upon entrance work.

Referring to Figure 10 to Figure 14, it is the present invention signal five kinds of different operating states:

Wherein, Figure 10 for initially entering working state schematic representation, Figure 11 be at driver element in working order in, Tu12Wei Deactivating in state, Figure 13 is for returning in original state, and Figure 14 is that driver element revert to original state and repeats to enter work Making state to be intended to, four driver elements are on main shaft 20, the most staggered (such as figure along main shaft 20 length direction in 45 degree of angles Shown in 15), when being in Figure 12 state with the first driver element, the second driver element is then in Figure 11 state, the 3rd driver element Being in Figure 10 state, the 4th driver element is then between Figure 13 state position and Figure 14 state position.

The present invention i.e. has AutoPlay function after completing to install, and its initial rotation energy is from second in Figure 11 state Driver element；

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

Wherein, the operation principle of the present invention is described with Figure 10 state-driven unit:

As a example by the length of swing arm 11 is 100: 1 with the diameter ratio of drive sprocket 21, during original state, at driver element In position as shown in Figure 10, main shaft 20 drives top power assembly 70 counterclockwise by drive sprocket 21, makes the first of cam 74 Chimb 741 abuts against with the second counterweight 63, the left end of jack-up rotating turret 63 so that the downward Gravity support of pressure assembly 60 is in convex On wheel 74, now, pressure wheel 62 belongs to released state with the thread groove 531 of tapered thread wheel 53, and, pressure wheel 62 is in Taking turns 53 thread groove 531 highest points with tapered thread, suspension 50 is in position, the end.At the right-hand member of swing span 10, only 1/2 weight of the suspension 50 that stay cord 40 applies.Now, the gravity of swing span 10 left side the first balancing weight 13 is more than stay cord 40 To the pulling force of swing span 10 right-hand member and swing span 10 left side toward drive shaft during lower swing rotate required for weight, therefore, pendulum Moving frame 10 left end is swung downward under the action of gravity of the first balancing weight 13 so that swing arm 11 drives annulus 34 counterclockwise rotation Dynamic, thus band pawl 32 promotes ratchet 31 counterclockwise, due to, ratchet 31 is Tong Bu connection with main shaft 20, ratchet 31 Drive again main shaft 20 counterclockwise, so that main shaft 20 externally exports rotational, when driver element runs to Figure 11 state, Swing span 10 has swung 45 °, and swing span 10 also drive shaft have rotated 45 °, meanwhile, because of drive sprocket 21 and drive sprocket 72 rotation ratios are 1: 2 so that main shaft 20 is by drive sprocket 21, and chain 71, driven sprocket 72 and power transmission shaft 73 drive cam 74 Have rotated 90 ° counterclockwise, now, the driver element being in rear stage initially enters duty, meanwhile, and the driving list of previous stage Unit then deactivates state.Driver element continues Figure 11 and runs to Figure 12 state, and during Figure 11 to Figure 12, this drives Main shaft 20 is then jointly done work by unit with a rear driver element, (is jointly to master from Figure 10 to Figure 11 with previous stage driver element Axle 20 rotates acting), when swinging to Figure 12 state under the left side of swing span 10, swing span 10 whole process has swung 90 °, meanwhile, pendulum Moving frame 10 have rotated 90 also by ratchet mechanism 30 drive shaft 20., cam 74 rotates 180 °, and now, it is right that driver element stops Main shaft 20 rotates acting, and main shaft 20 continues to rotate counterclockwise.

So far, driver element it is necessary to revert to just position, now, just need to use pressure to continue main shaft 20 is rotated acting Gravity is applied to swing span 10 right-hand member by suspension 50 and stay cord 40 by the gravity of power assembly 60, so that swing span 10 right-hand member Swung downward left end is raised, and therefore, in above work, cam 74 is after rotating 180 °, and the first chimb 741 starts and second Balancing weight 63 feather edge separates, the second chimb 742 of the feather edge reply cam 74 of the second balancing weight 63, and separated state, Rotating turret 61 left end loses support force so that under the action of gravity of pressure assembly 60, and pressure wheel is pressed in tapered thread wheel for 62 times On the thread groove 531 of 53, and, now pressure wheel 62 is pressed in tapered thread and takes turns on the thread groove 531 of 53 minimum points under being , reason is when swing span 10 left side is toward lower swing, and the right is upwards raised, and drives suspension 50 upwards by stay cord 40 Mobile, simultaneously as swing span 10 amplitude of fluctuation is the twice that suspension 50 moves up and down amplitude, raise on the right of swing span 10 Time, the stay cord 40 distance from swing arm 11 junction to roller 52 can incrementally increase, and fixes end from roller 52 to frame Distance the most progressively shortens, and thus drives roller 52 to rotate clockwise.Due to wheel shaft 51, it is Tong Bu with roller 52 that tapered thread takes turns 53 Interaction relation so that roller 52, wheel shaft 51 and tapered thread takes turns 53 synchronous axial system, and along with rotation moves up and along wheel Axle 51 length direction moves.Opposite face between tapered thread wheel 53 and pressure wheel 62 is made to rotate to lower from highest point.Therefore, Make the strong point of rotating turret 61 left end, from thread groove 531 minimum point that cam 74 is transferred to tapered thread wheel 53.Make pressure The gravity of power assembly 60, can pass through suspension 50 and stay cord 40 by weight transfer to swing span 10 right-hand member.Due to pressure wheel 62 It is the middle part being articulated between rotating turret 61 left end the second balancing weight 63 and rotating turret 61 right-hand member pivoting point, therefore, now pressure Assembly 60 is applied with the gravity that twice cam 74 is born to suspension 50, at pressure wheel 74 born institute gravity is namely During G, the gravity that now suspension is born is 2G.Thus, at the right and left of roller 52, all stay cord 40 is applied with one G pulls down, and simultaneously also has a reversal interlocking relay upwards, owing to the right-hand member of stay cord 40 is fixed in frame, thus, two to Under pulling force upwards be equal.On the left side of stay cord 40, owing to being attached on swing span 10 right-hand member, and swing span 10 Not being fixed, as long as the resistance that big first balancing weight 13 of the downward pulling force of right-hand member produces, swing span 10 right-hand member is downwards Swing.Thus, stay cord 40 pulling force upwards depends on the weight of the first counterweight fast 13, simultaneously as the weight of the first counterweight fast 13 Power is less than pressure assembly 60 (comprising suspension 50) to the downward pulling force that swing span 10 applies, and therefore, swing span 10 is right End produces pulling force upwards less than the downward pulling force of stay cord 40, thus, the right and left at roller 52 occur in that two the most reciprocity Upwards pulling force, the right is more than the left side, therefore, has an anticlockwise revolving force on two rollers 52, so that roller 52 Inverse time rotates, and moves down in rotation and move along wheel shaft 51 length direction, thus drives on the right of swing span 10 downward Swing makes the left side raise, and in the process, taking turns 53 due to roller 52 with wheel shaft 51 and tapered thread is Tong Bu connection, because of This, tapered thread wheel 53 is also as what roller 52 moved down in rotation, and thread groove 531 and pressure in rotation moves down The contact point of wheel 62 incrementally increases.It is i.e. the contact point from the central point of wheel shaft 51 to thread groove 531 with pressure wheel 62, can be with To move down and incrementally increase in rotation, and be equal with moving down height, say, that the central point of wheel shaft 51 moves down How many, drive tapered thread 63 to make thread groove 531 increase many with the contact point of pressure wheel 62 in moving down rotation simultaneously Few, make the left end of rotating turret 61 not move down, bottom the second balancing weight 63, keep released state with the second chimb 742.Thus, Pressure assembly 60 can be made to produce downward pressure be applied to all the time on suspension 50, and be delivered to swing span 10 through lifting rope 40 Right-hand member, makes swing span 10 right-hand member and suspension 50 swung downward simultaneously, and left end is raised, meanwhile, in swing span 10 up time When pin swings, due to the unidirectional drive performance of ratchet mechanism 30, now main shaft 20 drives ratchet 31 to continue to rotate counterclockwise, and swings Frame 10 then band pawl 32 rotates clockwise, and the front end of ratchet 32 slips over from the ratchet back of tooth, when driver element runs to Figure 14 shape During state, driver element revert to original state.Speed due to swing span 10 clockwise oscillation is more than the rotary speed of main shaft 20, Now cam 74 does not turns to the first chimb 741 and connects with balancing weight 63, and therefore, driver element can stop at the state of Figure 14 Middle wait.

So far, as long as driver element pressure relief assembly 60 is applied to swing span 10 right side by suspension 50 and stay cord 40 Downward pulling force, the most repeatable main shaft 20 is rotated is held to do work, therefore, when main shaft 20 drives top power assembly by drive sprocket 21 70 counterclockwise, when making the first chimb 741 contact with the second balancing weight 63 feather edge.Now, it is necessary to be in Figure 11 state In driver element pay certain energy, drive drive sprocket 21 by main shaft 20, drive top power assembly 70 by rotating turret 61 Left end jack-up, make pressure wheel 62 separate with thread groove 531, with pressure relief assembly 60, swing span 10 right-hand member applied downwards Pulling force, the gravity of pressure assembly 60 is transferred to cam 74 from suspension 50.Due to, pressure assembly 60 is to swing span 10 Right-hand member applies downward pulling force, is greater than 20% one the 80% of the first balancing weight 13 weight, and cam 74 is from power transmission shaft 73 The heart to the height of the first chimb 741 less than the radius of drive sprocket 72, meanwhile, the gravity that cam 74 is born and pressure assembly 60 The gravity being applied to swing span 10 right-hand member is equal, thus, when the resistance suffered by cam 74 is delivered to drive chain 21, Also the twice resistance of the first gravity joining block 13 it is equivalent to.It is to say, now at drive chain 21, have two the first balancing weights The gravity of 13, stops it to rotate counterclockwise.Due to, the length of swing arm 11 is 100: 1 with the diameter ratio of drive sprocket 21, by This, the torsion namely 100 times that drive sprocket 21 is produced by the first balancing weight 13 by swing span 10, therefore, as long as first joins Pouring weight 13 can drive drive sprocket 21 to rotate counterclockwise by the weight of 3% to 10%, thus band moving cam 74 is by pressure assembly 60 left end jack-up, make pressure wheel 62 feather edge separate with the thread groove 531 of tapered thread wheel 53 so that the support of pressure group 60 Point is transferred to top power assembly 70 from tapered thread 53, by cam 74 first chimb 741 as the strong point, thus relieves pressure The gravity that group 60 is applied to swing span 10 right-hand member by suspension 50 and stay cord 40.Swing span 10 right-hand member is made to only have suspention group The weight that part 50 applies, so that the first balancing weight 13 repetitive cycling rotates acting to main shaft 20, repeats with work process.With Time, the weight of the first balancing weight 13 also has 70%-90% for as externally exporting power.

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 present invention is arranged in order and synchronizes connection along the length direction (i.e. X to) of frame Connecing, described main shaft 20 actually may be configured as one, and four driver elements share this main shaft 20.

Refer to Fig. 8, as further improving, except aforementioned four driver element, an idle driving also can be set Unit, when one of them of aforementioned four driver element breaks down and need repairing, suspends this driver element, and starts described Idle driver element just can, thus can make to be not required to overall shutdown, concrete implementation mode is: described drive sprocket 72 is provided with interior eight Angle body 721, this end of power transmission shaft 73 is set to octahedron, and the octahedron of power transmission shaft 73 can be inserted in the interior anise of drive sprocket 72 In body 721, meanwhile, in drive sprocket 72, octet 721 top edge offers screw hole (not indicating in figure), has in screw hole One screw 722, screw 722 is connected on described power transmission shaft 72 one of them face octahedral, so that power transmission shaft 73 and transmission Sprocket wheel 72 realizes fixed relationship；When there being driver element to need maintenance maintenance, unclamp screw 722, drive sprocket 72 from transmission The octahedron of axle 73 exits, then the power transmission shaft 73 of the idle driver element of regulation so that it is the angle of cam 74 and the angle of swing span The phase place of the driver element spent and suspend keeps consistent, then drive sprocket 72 reinstalls power transmission shaft 73 octahedron by screw 722 tighten fixing, the locating dowel 223 on the clutch plate 22 of idle driver element push the hole, location 211 of drive sprocket 21, i.e. Can start this free time driver element, then will need to overhaul the clutch plate 22 of driver element, clutch plate is pushed away master by logical pull bar 24 Movable sprocket 21, makes locating dowel 223 exit in hole 211, location, just can complete to suspend driver element to be repaired, again can conduct after maintenance New idle driver element, for replacing new fault driver element.

In sum, the gravity that the present invention utilizes the first balancing weight 13 to produce swing span 10 left end passes through ratchet mechanism 30 Moment is put on main shaft 20, the power source rotated is provided for main shaft 20, meanwhile, utilizes the gravity of pressure assembly 60 through suspention group Part 50 and stay cord 40 are applied to the right-hand member of swing span 10 in the way of transmission, make the first balancing weight 13 revert to initial position, weight Multiple circulation rotates acting to main shaft 20, thus, can make under the cooperating of four driver elements, and the present invention is gone round and begun again Rotation, thus realize in the case of less without other power or other power, make main shaft 20 rotate constantly, by externally Output rotational power drives electrical power generators, therefore, the present invention can reduce and utilizes coal, gasoline, natural gas equal energy source to generate electricity Consumption, and will not in atmospheric environment discharge harmful, reduce environmental pollution.

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