Figure 12 to Figure 15 is referred to, it is the schematic diagram of the invention in four kinds of different working conditions：

Wherein, Figure 12 is initially enters working state schematic representation, and Figure 13 is that driver element is in working condition, Tu14Wei Exit in working condition, Figure 15 is returns in original state, and the cam 74 of four driver elements is staggered in an angle of 90 degrees.So that When first driver element is in Figure 12 states, the second driver element is then in Figure 13 states, and the 3rd driver element is in Figure 14 shapes State, the 4th driver element is then between Figure 15 state positions and original state (Figure 12) position.And make in Figure 13 states Driver element is among main axis acting, so that the present invention completes have initial launch function after installing.

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

Wherein, the operation principle of the present invention is illustrated with Figure 12 state-drivens unit：

Taken two turns with rotation of haulage drum 10 of the first balancing weight 12 work, drive sprocket 21 drives the first sprocket wheel 72 to rotate Exemplified by 180 °, during original state, main shaft 20 drives the counterclockwise rotation of the first sprocket wheel 72 by drive sprocket 21 through the first chain 71, the One sprocket wheel 72 with moving cam 74, the 3rd gear 75 and the counterclockwise of first gear 91, makes the first convex of cam 74 through rotating shaft 73 Side 741 is abutted 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 cam On 74, the screw thread chimb 531 of the groove of pressure wheel 62 and tapered thread wheel 53 belongs to released state, meanwhile, first gear 91 belongs to Idling conditions, also, the groove of pressure wheel 62 with the highest point of 53 screw thread chimb of tapered thread wheel 531, suspension 50 is in Most bottom position so that driver element is in state as shown in figure 12.In the right-hand member of roller 10, only suspension 50 passes through The weight that drawstring 40 applies.Now, the gravity of the first balancing weight of the left side 12 of roller 10 is applied more than drawstring 40 to the right-hand member of roller 10 Plus resistance and roller 10 when rotating counterclockwise drive shaft 20 rotate energy external required for output power, therefore, roller 10 Left end counterclockwise under the Action of Gravity Field of the first balancing weight 12, so as to drive the counterclockwise of annulus 34, and then drives spine Pawl 32 promotes the counterclockwise of ratchet 31, because again ratchet 31 is synchronous connection with main shaft 20, and ratchet 31 drives main shaft 20 Counterclockwise, so that main shaft 20 externally exports power.When roller 10 is rotated counterclockwise, two drawstrings 40 are twined to roller 10 Around so that drawstring 40 gradually shorten, thus drive suspension 50 rotate clockwise and moved up in rotation and Along the motion of the length direction of wheel shaft 51.When driver element runs to Figure 13 states, the inverse time of 12 haulage drum of the first balancing weight 10 Pin have rotated a circle, one circle also by the counterclockwise of 30 drive shaft of ratchet mechanism 20 of roller 10, while main shaft 20 passes through Drive sprocket 21, the first chain 71, the first sprocket wheel 72 and the driving cam 74 of rotating shaft 73, the 3rd gear 75 and the inverse time of first gear 91 Pin have rotated 90 °, now, and the driver element for being in rear stage initially enters working condition, meanwhile, the driver element of previous stage is then Exit working condition.Driver element continues to run from Figure 13 to Figure 14 states, during from Figure 13 to Figure 14, this driving It (is common to master with previous stage driver element from Figure 12 to Figure 13 that unit then does work to main shaft 20 jointly with rear stage driver element Axle 20 rotates acting), when driver element runs to Figure 14 states, the whole counterclockwise of haulage drum 10 of the first balancing weight 12 Two circles, while roller 10 is also that have rotated two circles, cam 74, the 3rd gear 75 counterclockwise by the drive shaft 20 of ratchet mechanism 30 And 180 ° of the counterclockwise of first gear 91, the first chimb 741 is separated with the feather edge of the second balancing weight 63, while the first tooth Wheel 91 also rotates to teeth portion part and engaged with second gear 92, roller 10 is realized synchronous interaction relation, so far, first with main shaft 20 Balancing weight 12, which stops rotating main shaft 20, to do work, and driver element completes the process that acting is once rotated to main shaft 20, main shaft 20 Continue to rotate counterclockwise under the driving of subsequent drive unit.Now, the feather edge of the second balancing weight 63 tackles the second chimb 742, The left end of rotating turret 61 loses support force so that under the Action of Gravity Field of pressure assembly 60, and taper spiral shell is pressed under the groove of pressure wheel 62 In the convex mistake 531 of screw thread of line wheel 53, so that the Gravity support point of the left end of rotating turret 61 is transferred to the pressure at middle part from cam 74 62 are taken turns by suspension 50 as the strong point, so that the gravity of pressure assembly 60 is able to through suspension 50 and drawstring 40 By the right-hand member of weight transfer to roller 10.Simultaneously as pressure wheel 62 be articulated in the second balancing weight of left end 63 of rotating turret 61 with Middle part between the right-hand member pivoting point of rotating turret 61, therefore, now pressure assembly 60 is applied with twice of cam 74 to suspension 50 The gravity born, that is, when pressure wheel 74 bears institute's gravity for G, the gravity that now suspension 50 is born is two G.Thus, include the weight of the application of suspension 50, in roller 52 and the right and left of wheel shaft 51, one all is applied with to drawstring 40 More than the downward pulling force of a G (because the gravity suffered by cam 74 does not include the gravity that suspension 50 applies), while drawstring 40 There is a upward reversal interlocking relay, right section due to drawstring 40 is fixed in frame, thus, two downward upward pulling force are Equal.At left section of drawstring 40, due to being connected on roller 10, and roller 10 is not fixed, as long as rolling The resistance that big the first balancing weight of left end 12 of the downward pulling force of 10 right-hand members of cylinder is produced, roller 10 can be rotated clockwise.Due to pressure The gravity of power component 60 is more than the resistance that the first counterweight fast 12 is produced, and therefore, the right-hand member of roller 10 has under the pulling of drawstring 40 One trend that rotates clockwise, and in the presence of the clockwise rotatory force of pressure wheel 62 is to screw thread chimb 531, make taper spiral shell There is an anticlockwise revolving force on line wheel 53, roller 52 and wheel shaft 51, so that tapered thread wheel 53, roller 52 and wheel shaft 51 rotations counterclockwise, and moved down and along the motion of the length direction of wheel shaft 51 in rotation, so as to drive roller 10 clockwise Rotate, in the process, due to roller 52 be with wheel shaft 51 and tapered thread wheel 53 be it is synchronous couple, therefore, tapered thread Wheel 53 be also as roller 52 is moved down in rotation, and rotate move down in screw thread chimb 531 and the groove of pressure wheel 62 Contact point is incrementally increased, be from the central point of wheel shaft 51 to screw thread chimb 531 with the contact point of the groove of pressure wheel 62, can be with Move down and incrementally increased in rotation, and be equal with moving down height, that is to say, that the central point of wheel shaft 51 is moved downwardly How much, while driving tapered thread 53 to increase the contact point of screw thread chimb 531 and the groove of pressure wheel 62 in rotation is moved down How much, the left end of rotating turret 61 is not moved down, the bottom of the second balancing weight 63 keeps released state (such as with the second chimb 742 Shown in Figure 15).Thus, it may be such that pressure assembly 60 has a downward gravity to be applied on suspension 50 all the time, and through drawing Rope 40 is delivered to the right-hand member of roller 10, rotates clockwise roller 10, while so that lifting rope 11 is wound to roller 10, so as to drive First balancing weight 12 is moved up, at the same time, when roller 10 is rotated clockwise, due to the unidirectional drive of ratchet mechanism 30 Can, now main shaft 20 drives ratchet 31 to continue to rotate counterclockwise, and then band pawl 32 is rotated clockwise roller 10, before ratchet 32 End is slipped over from the back of tooth of ratchet 31, and when first gear 91, which is turned to, departs from driving relationship with second gear 92, driver element is returned To original state.Cam 74 also rotates to the first chimb 741 and connected with the second balancing weight 63 and the left end of jack-up rotating turret 61 simultaneously, The groove of pressure wheel 62 is separated with screw thread chimb 531, the Gravity support point of pressure assembly 60 is transferred to from suspension 50 convex On wheel 74, the power turned clockwise applied with pressure relief component 60 by suspension and drawstring 40 to the right-hand member of roller 10 Square, makes the left end of roller 10 be rotated counterclockwise under the Action of Gravity Field of the first balancing weight 12, driver element is again introduced into working condition Main shaft 20 is rotated and done work, said process is repeated.Such iterative cycles so that under the mutual cooperation of four driver elements, it is main Axle 20 is able to lasting rotation and externally exports power.

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

Referring to Fig. 8, 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 First sprocket wheel 72 is provided with interior octet 721, and the end of rotating shaft 73 is set to octahedra, and the octahedron of rotating shaft 73 can be inserted in first In the interior octet 721 of sprocket wheel 72, meanwhile, the top edge of octet 721 offers screw hole and (not marked in figure in the first sprocket wheel 72 Show), there is a screw 722 in screw hole, screw 722 is connected on the octahedral one of face of the rotating shaft 73, so that turning The sprocket wheel 72 of axle 73 and first realizes fixed relationship；When there is driver element to need to overhaul maintenance, screw 722 is unclamped, the first chain Wheel 72 is exited from the octahedron of rotating shaft 73, is then adjusted the rotating shaft 73 of idle driver element, is made angle and the driving of its cam 74 The phase of unit and the driver element of pause is consistent, then the first sprocket wheel 72 is loaded into the octahedron of rotating shaft 73 by screw 722 tighten fixation, the locating dowel 223 on the clutch plate 22 of idle driver element are pushed into the positioning hole 211 of drive sprocket 21, i.e., The idle driver element can be started, the clutch plate 22 of maintenance driver element then will be needed, clutch plate is pushed away master by logical pull bar 24 Movable sprocket 21, makes locating dowel 223 be exited out of positioning hole 211, just can complete to suspend driver element to be repaired, after maintenance but also as New idle driver element, the failure driver element new for replacing.

In summary, the gravity that the present invention is applied using the first balancing weight 12 to the left end of roller 10 will by ratchet mechanism 30 Torque is put on main shaft 20, is that main shaft 20 provides the power source rotated, using the gravity of pressure assembly 60 through suspension 50 and Drawstring 40 is applied to the right-hand member of roller 10 in the way of transmission, the first balancing weight 12 is revert to initial position, repetitive cycling pair Main shaft 20 rotates acting, thus, can make under the mutual cooperation of four driver elements, and the present invention is able to the rotation gone round and begun again, So as to realizing in the case of less without other power or other power, main shaft 20 is set constantly to rotate, therefore, the present invention can be with Reduce coal, gasoline, the consumption of natural gas equal energy source, and will not into atmospheric environment discharge harmful, reduce environment dirty Dye.

According to such scheme, the present invention can also make it is a kind of differ in size, for as sight, and be adapted to various The handicraft that occasion is laid, makes the present invention play maximum economic value.

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.
