Figure 11 to Figure 16 is referred to, it is schematic diagram of the present invention in six kinds of different working conditions：

Wherein, to initially enter working state schematic representation, Figure 12 and Figure 13 is at driver element in working order Figure 11 In, to deactivate in state, during Figure 15 is to return original state, Figure 16 revert to original state for driver element to be repeated Figure 14 Into working state schematic representation, the cam 107 of two driver elements is in the staggered installation in 180 degree angle.So that two drive list After unit completes to install, when being in Figure 11 states with the first driver element, the second driver element is then in Figure 13 states, and causes Driver element in Figure 13 states is in and main shaft 20 is rotated in the middle of acting.So that the present invention has just after completing to install Beginning operation function.

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

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

Turned clockwise 380 ° with a driver element haulage drum 10 of work, main shaft 20 passes through the Jing chains of drive sprocket 21 104th, sprocket wheel 105 and the driving cam 107 of rotating shaft 106 rotate clockwise 190 °.First chimb 1071 contacts angle of rotation with pulley 103 Spend for 190 degree, as a example by 170 degree of 103 rotational angle of the reply pulley of the second chimb 1072, during original state, main shaft 20 drives actively Sprocket wheel 21 is rotated clockwise, due to sprocket wheel 105 and the synchronous connection of 21 Jing chains of drive sprocket 104, so that sprocket wheel 105 is logical Cross rotating shaft 106 to rotate clockwise with moving cam 107, the first chimb 1071 for making cam 107 is contacted and to rotating turret with pulley 103 101 left end is pressed down so that the right-hand member in the presence of pressure wheel 102 of rotating turret 101 is moved up, and makes two cylinders 108 upwards Compression is produced to stage clip 110 when mobile, so that 110 pairs of two cylinders 108 of stage clip have a reverse pressure, is thus made Obtaining rotating turret 101 has a downward pressure Jing pressure wheel 102 to be applied on suspension 50, so that drawstring 40 has one Downward pulling force, meanwhile, drawstring 40 also has a reversal interlocking relay upwards, because right section of two drawstrings 40 (is from wheel shaft 51 To the fixing point of frame) it is fixed in frame, thus, two pulling force downwards upwards are equal.Drawstring 40 left section (from Wheel shaft 51 arrives a section of cylinder 10), due to being connected on cylinder 10, and cylinder 10 is not fixed, as long as rolling The torque for rotating clockwise that 10 right-hand members of cylinder apply is more than the counterclockwise that the left end balancing weight 12 of cylinder 10 applies to cylinder 10 Torque, and cylinder 10 when rotating clockwise drive shaft 20 rotate energy external required for output power and mechanical friction Loss, cylinder 10 can be rotated clockwise.Due to pressure assembly 100 produce pressure (including rotating turret 101, pressure wheel 102 and The gravity that suspension 50 applies) weight and drive shaft 20 that are greater than balancing weight 12 rotates clockwise externally output power What required energy and mechanical friction was lost, therefore, the right-hand member of cylinder 10 has one to rotate clockwise under the pulling of drawstring 40 Trend so that the drawstring 40 in the right and left of wheel shaft 51 occurs in that two not reciprocity pulling force upwards, the right is more than The left side so that have an anticlockwise revolving force on wheel shaft 51, so that the counterclockwise of wheel shaft 51, and in rotation downwards Movement is simultaneously moved along the length direction of wheel shaft 51, so as to drive cylinder 10 to rotate clockwise, so that lifting rope 11 is to cylinder 10 Winding, so as to drive balancing weight 12 to move up.In the process, because wheel shaft 51 and tapered thread wheel 52 are synchronous connections 's.Therefore, tapered thread wheel 52 is also and the thread groove in rotation is moved down as wheel shaft 51 is moved down in rotation 521 incrementally increase with the contact point of pressure wheel 102.It is from the central point of wheel shaft 51 to thread groove 521 and pressure wheel 102 Contact point, can incrementally increase with moving down in rotation, and be equal with height is moved down.That is, in wheel shaft 51 Heart point is moved downwardly how many, while driving tapered thread wheel 52 thread groove 521 is connect with pressure wheel 102 in rotation is moved down Contact increases how many, makes rotating turret 101 not move down in the presence of tapered thread wheel 52, makes 1071 pairs of cunnings of the first chimb Wheel 103 keeps pressed status.Thus, pressure assembly 100 (rotating turret 101) can be caused to have a downward pressure to be applied to all the time On suspension 50, and power source is delivered to Jing drawstrings 40 right-hand member of cylinder 10, rotates clockwise cylinder 10, works as driver element When running to Figure 13 states, the pressure that pressure assembly 100 is produced is clockwise by suspension 50 and the haulage drum 10 of drawstring 40 360 ° are have rotated, cylinder 10 has rotated clockwise 360 ° also by the drive shaft 20 of ratchet mechanism 30, so that 20 pairs, main shaft Outer output power.Simultaneously main shaft 20 passes through the Jing chains 104 of drive sprocket 21, sprocket wheel 105 and the up time of 106 driving cam of rotating shaft 107 Pin have rotated 180 °.Now, the driver element for being in rear stage initially enters working condition.Driver element continues from Figure 13 to figure 14 states are run, and during the state from Figure 13 to Figure 14, this driver element is then with rear stage driver element jointly to main shaft 20 rotate acting, and when driver element runs to Figure 14 states, the whole haulage drum 10 of drawstring 40 has rotated clockwise 380 °, while Cylinder 10 is also to have turned clockwise 380 ° by the drive shaft 20 of ratchet mechanism 30, and cam 107 has rotated clockwise 190 °.This When, two driver elements complete work handover process, and rear stage drives single-enter normal operating conditions to rotate main shaft 20 and does work, First chimb 1071 of previous stage driver element is separated with pulley 103, and the reply pulley 103 of the second chimb 1072 is simultaneously separated State, pressure assembly 100 is applied to the pressure releases on suspension 50, there was only pressure frame 101 and pressure on suspension 50 The gravity that wheel 102 applies, so far, driver element stops rotating acting to main shaft 20, and driver element is completed once to main shaft 20 Rotate the process of acting.Now, the counterclockwise under the action of gravity of balancing weight 12 of cylinder 10, makes two drawstrings 40 to cylinder 10 Winding, so as to driving suspension 50 to rotate clockwise and moving up in rotation and along the length direction of wheel shaft 51 fortune Dynamic, when wheel shaft 51 is moved upwards up to connector, driver element revert to original state, due to the speed of the counterclockwise of cylinder 10 More than the speed that rotates clockwise, cam 107 now is also not rotated to the first chimb 1071 and contacts with pulley 103 degree, because This driver element is rested in the position of setting and waited.In reseting procedure, due to the unidirectional drive performance of ratchet mechanism 30, with Main shaft 20 departs from driving relationship, drives ratchet 31 to continue to rotate clockwise under the driving of the driver element below of main shaft 20.Cylinder 10 drive annulus 34 and the counterclockwise of ratchet 32, and the front end of ratchet 32 slips over from the back of tooth of ratchet 31.When cam 107 is turned to First chimb 1071 contact with pulley 103 and the left end of rotating turret 101 is stayed pressure when (as shown in figure 16), driver element is i.e. again Secondary entrance working condition is rotated to main shaft 20 and done work, and 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 Certain energy is assisted and paid to the driver element for needing previous stage (driver element in Figure 13 states), could enter repetition Circulation working condition is rotated to main shaft 20 and done work.

Therefore, under the cooperating of two driver elements, main shaft 20 is able to lasting rotation and externally exports the present invention Power.

The main shaft 20 of two 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 two driver elements share the main shaft 20.

Fig. 8 is referred to, as further improvement, except above-mentioned two driver element, an idle driving can be also set Unit, when above-mentioned two 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, offer screw hole in the outward flange of the interior octet 1051 of sprocket wheel 105 and (do not mark 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 as to 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, then adjust the rotating shaft 106 of idle driver element so as to cam 107 Angle be consistent with the phase place of driver element to be repaired, then sprocket wheel 105 is loaded 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 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 the pressure that pressure assembly 100 is produced be applied on suspension 50 Jing drawstrings 40 with The mode of transmission is applied to the right-hand member of cylinder 10, rotates clockwise cylinder 10, and by ratchet mechanism 30 main shaft 20 is put on, and is Main shaft 20 rotates the power source that provides, and the gravity applied to the another side of cylinder 10 using balancing weight 12 drives driver element to revert to just Beginning state repetitive cycling is rotated to main shaft 20 and done work.Thus, can make under the cooperating of two driver elements, the present invention is able to The rotation for going round and beginning again, so as to realize in the case of less without other power or other power, main shaft 20 is constantly rotated, And externally export the power of rotation.Meanwhile, the present invention is changeable so that its range of application is wider, when it is midget plant When, can be applicable to the modern means of communication such as automobile, steamer is used to drive the modern times electronic by output power drive electrical power generators The vehicles and average family are used to generate electricity, and when it is large-scale, during middle- scale device, can be applicable to various industrial and mining establishment, each city City's unit is generated electricity, therefore the present invention can reduce the consumption of the energy, and will not be subtracted to discharge harmful in atmospheric environment Few environmental pollution.
