suspension 50 is in vacant state, to make the gravity of suspension 50 and be transferred to two drawings from top power component 60 On rope 40, the right end and drawstring 40 that thus make suspension 50 there is a downward gravity to be transmitted to swinging frame 10 through drawstring 40 Fixing end, be fixed on the rack due to the right end (from idler wheel 52 to rack fixed point) of drawstring 40, thus two downwards to On pulling force be equal, on the left side (from idler wheel 52 to 10 right end of swinging frame) of drawstring 40 be connected on 10 right end of swinging frame , and swinging frame 10 is not fixed, as long as right end applies downward pulling force and is greater than the resistance that clump weight 13 generates, pendulum 10 right end of moving frame can be to lower swing, therefore 10 right end of swinging frame has becoming to lower swing under the pulling of drawstring 40 Gesture so that there is an anticlockwise rotary force on idler wheel 52 so that 52 inverse time of idler wheel rotates, and in rotation to Lower movement is simultaneously moved along 51 length direction of wheel shaft, so that the right of swinging frame 10 be driven to raise the left side to lower swing, thus band Dynamic driving unit is run to original state, in the process, the point corresponding with top 62 groove of wheels of screw thread chimb 531 can with turn It moves and is gradually reduced in moving down, that is, the central point of wheel shaft 51 is moved downwardly how many in rotation, while driving tapered thread Wheel 53 reduces how many in rotation moves down, and so that screw thread chimb 531 and top wheels 62 is remained at discrete state, thus can make The right end that suspension 50 has a gravity to be transmitted to swinging frame 10 through drawstring 40 always makes 10 right end of swinging frame and suspension 50 move down simultaneously, and when swinging frame 10 runs to Figure 11 state, cam 67 and driving gear 75 have rotated 180 degree, drive 75 part tooth of gear, which is turned to, is disengaged from state with transmission gear 72, and the first chimb 671, which is turned to, contacts jack-up with pulley 63 61 left end of rotating turret, make push up wheels 62 contact with screw thread chimb 531 jack-up suspension 50, make suspension 50 gravity and from Two drawstrings 40 are transferred on the power component 60 of top, to relieve the gravity that suspension 50 applies 10 right end of swinging frame, make to put 10 left end of moving frame is to swing under the gravity of clump weight 13, and so far driving unit is again introduced into working condition after returning initially Main shaft 20 is rotated and is done work, is repeated the above process.Circulation is so that under the mutual cooperation of four driving units repeatedly, main shaft 20 are able to lasting rotation and external output power.

The main shaft 20 of four driving units of the invention arranged along the length direction (i.e. X to) of rack and it is synchronous couple, institute It states main shaft 20 actually and may be configured as one, four driving units share the main shaft 20.

Referring to Fig. 8, as a further improvement, in addition to aforementioned four driving unit, an also settable idle driving Unit suspends the driving unit, and described in starting when one of failure of aforementioned four driving unit needs repairing Thus idle driving unit can make to be not required to whole shutdown, can maintain into maintenance.Concrete implementation mode is: the drive Movable sprocket 65 is equipped with interior octet 651, and the end of shaft 66 sets octahedron, and the octahedron of shaft 66 can be inserted in drive sprocket In 65 interior octet 651, and 651 top edge of octet offers screw hole (not indicating in figure) in drive sprocket 72, There is a screw 652 in screw hole, which can be connected on the octahedral one of face of the shaft 66, to make to turn Axis 66 and drive sprocket 65 realize fixed relationship；When there is driving unit to need to overhaul maintenance, screw 652 is unclamped, drive chain Wheel 65 is exited from the octahedron of shaft 66, then adjusts the shaft 66 of idle driving unit, make its cam 67, driving gear 75 and The phase of the driving unit of the angle and pause of swinging frame is consistent, then drive sprocket 65 is reinstalled 66 octahedron of shaft Screw 652 is tightened into fixation, the positioning column 223 on the clutch plate 22 of idle driving unit is pushed into the location hole of drive sprocket 21 211, the free time driving unit can be started, then will need to overhaul the clutch plate 22 of driving unit, lead to pull rod 24 for clutch plate 22 push away drive sprocket 21, exit positioning column 223 out of location hole 211, can complete to suspend driving unit to be repaired, after maintenance But also as new idle driving unit, for replacing new failure driving unit.

In conclusion the present invention passes through ratchet mechanism 30 for power to the gravity that 10 left end of swinging frame generates using clump weight 13 Square is applied on main shaft 20, is provided the power source of rotation for main shaft 20, is transferred to pendulum through drawstring 40 using the gravity of suspension 50 10 right end of moving frame drives driving unit to revert to original state repetitive cycling and rotates acting to main shaft 20, thus can make at four Under the mutual cooperation of driving unit, the present invention is able to rotation in cycles, to realize without other power or other power In lesser situation, rotate main shaft 20 constantly and externally export rotational power, thus the present invention can reduce using coal, The consumption of the energy such as gasoline, natural gas, and will not into atmospheric environment discharge harmful, reduce environmental pollution.

Working principle according to the present invention can also make a kind of for ornamental value, and various Environment spaces is suitble to place Craftwork makes utility value of the invention perform to maximum economic benefit.
