Top in two cylindrical drum 109 is equiped with stage clip 110, and the top of two cylinders 108, two cylinders are pressed under the bottom of the stage clip 110 108 can produce compression to stage clip 110 when moving up.It is provided with the top of two cylindrical drum 109 and presses for adjusting stage clip 110 The device parallel connection of power size is connected to pressure gauge (figure is not indicated), for looking around the pressure that stage clip 110 is produced to 101 right-hand member of rotating turret Numerical value, the stage clip 110 can also be arranged on the downward tension spring of 101 right-hand member of rotating turret.Two cylindrical drum 109 are fixed on frame On.102 warp beam of the pressure wheel is held and is articulated on the middle part of rotating turret 101, that is, 101 left end connecting rod of rotating turret and rotation Between 101 right-hand member of frame, two cylinder, 108 pivoting point, middle part, is pressed in the screw thread of tapered thread wheel 52 under the feather edge of the pressure wheel 102 In groove 521；Specifically, the tapered thread wheel 52 foreign steamer week, be provided with around from the minimum position of tapered thread wheel 52 to Maximum position direction turns clockwise the thread groove 521 (as shown in Figure 7) of extension, when tapered thread wheel 52 rotates counterclockwise When, pressure wheel 102 can go to peak from minimum point with the thread groove 521 of tapered thread wheel 52, when tapered thread wheel 52 When rotating clockwise, pressure wheel 102 goes to minimum point from 52 peak of tapered thread wheel again, in the process, pressure wheel 102 It is to rotate with tapered thread wheel 52, will not be upper and lower and movable, only tapered thread wheel 52 is moved up and down in rotation And along the length direction motion of wheel shaft 51；Therefore, the work for rotating counterclockwise and rotating clockwise in tapered thread wheel 52 During, rotating turret 101 remains at certain altitude.107 Jing rotating shafts of the cam, 106 synchronous connection has sprocket wheel 105, and convex Wheel 107 extends to the top of 101 left end connecting rod of rotating turret, has a pulley 103 by bearing hinge joint, make cam in connecting rod 107 pairs of 101 left ends of rotating turret contact rotation with pulley 103 when pressing down, it is also possible to do not set pulley 103, make cam 107 directly with The contact of 101 left end connecting rod of rotating turret is rotated, thus may increasing friction force.The sprocket wheel 105 passes through chain 104 and drive chain Wheel 21 is synchronous to be coupled, and rotating shaft 106 is by bearing hinge joint in frame.It is convex that the cam 107 is provided with the first chimb 1071 and second Side 1072 (as shown in Figure 9), also, the first chimb 1071 is higher than the second chimb 1072.Specifically, drive sprocket 21 is in main shaft 20 Drive under, rotated clockwise with movable sprocket 105 by chain 104, due to 107 Jing rotating shafts 106 of cam it is synchronous with sprocket wheel 105 Connect so that cam 107 is rotated clockwise, make the first chimb 1071 contact with pulley 103 and to 101 left end of rotating turret down Pressure, rotating turret 101 is in the presence of pressure wheel 102 so that the right-hand member of rotating turret 101 is moved up, so that 108 pairs, two cylinder Stage clip 110 produces compression, so that rotating turret 101 has a downward pressure to be applied to suspention by pressure wheel 102 Power source is transferred to 50 Jing drawstrings 40 of group the right-hand member of swing span 10, makes 10 clockwise oscillation of swing span, so that swing span 10 is left End is raised, after cam 107 rotates 180 degree, after the first chimb 1071 is separated with pulley 103, the reply pulley of the second chimb 1072 103 and separated state, cam 107 does not have pressure to act on the left end of rotating turret 101, and 101 right-hand member of rotating turret is in stage clip 110 Move down under effect.The pressure releases that pressure assembly 100 applies to suspension 50, now on drawstring 40 only have rotating turret 101st, the gravity that pressure wheel 102 and suspension 50 apply.That is the right-hand member in swing span 10 only has rotating turret 101, pressure The gravity that wheels 102 and suspension 50 apply, so that swing span 10 is put under the action of gravity of balancing weight 13 counterclockwise It is dynamic, raise 10 right-hand member of swing span, so as to drive two drawstrings 40 to move up, so as to drive suspension 50 to rotate clockwise simultaneously Move up and along the length direction motion of wheel shaft 51, thus drive driver element to return original state and repeat to main shaft 20 Rotate acting.

Please referring particularly to Fig. 6, the position-limit mechanism 60 is installed in frame, and the position-limit mechanism 60 is by being fixed in frame Four bumping posts composition, one group two-by-two of four bumping posts, external peripheral surface of two groups of bumping posts difference blockings at 51 two ends of wheel shaft, two groups of gears The top of post is provided with connector, and position-limit mechanism 60 is used to only limit wheel shaft 51 in above-below direction and along the shifting of 51 length direction of wheel shaft It is dynamic, and the peak for moving up.Specifically, when swing span 10 is swung counterclockwise, due to the unidirectional drive of ratchet mechanism 30 Dynamic performance, swing span 10 and 20 no interaction relation of main shaft, driver element are difficult to keep and main shaft 20 in original state is returned It is synchronous, that is to say, that to pass through 21 Jing chains of drive sprocket, 104 sprocket wheel, 105 rotating shaft 106 with moving cam 107 first in main shaft 20 When chimb 1071 is contacted with pulley 103, swing span 10 drives suspension 50 to be difficult to keep the synchronous position for being returned to setting, mistake It is slow too fast all uncoordinated to mechanical movement, will ultimately result in shutdown.Therefore, the speed that 10 inverse time of swing span rotates will be faster than main shaft 20 speed for rotating clockwise, make driver element revert to original state in advance, are moved upwards up to locating part in suspension 50 Can not move up again, driver element is waited in resting on setting position.

Figure 10 to Figure 14 is referred to, which is schematic diagram of the present invention in five kinds of different working conditions：

Wherein, Figure 10 initially enters working state schematic representation for driver element, Figure 11 be at driver element in working order In, to deactivate in state, to return in original state, Figure 14 revert to original state with weight for driver element to Figure 13 to Figure 12 It is intended to into working condition again, the gradual staggered installation in an angle of 90 degrees in frame of cam 107 of four driver elements makes The swing span 10 of four driver elements is in as shown in figure 15 from the side, when being in Figure 10 states with the first driver element, second Driver element is then in Figure 11 states, and the 3rd driver element is in Figure 12 states, and the 4th driver element is then in Figure 13 mode bits Put between Figure 14 state positions.And cause Figure 11 states in driver element in main shaft 20 rotate acting in the middle of, by This causes the present invention to have 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, Now main shaft 20 and drive sprocket 21 are the relations of synchronous connection；

Wherein, with Figure 10 state-drivens unit come illustrate the present invention operation principle：

By taking gear ratio 1: 2 of the drive sprocket 21 with sprocket wheel 105 as an example, during original state, driver element is in such as Figure 10 institutes The state shown, main shaft 20 drive drive sprocket 21 rotate clockwise, due to sprocket wheel 105 it is synchronous with 21 Jing chains 104 of drive sprocket Connection, so that sprocket wheel 105 is rotated clockwise with moving cam 107 by rotating shaft 106, make the first chimb of cam 107 1071 are contacted with pulley 103 and the left end to rotating turret 101 is pressed down so that rotating turret 101 is right in the presence of pressure wheel 102 End moves up, and moves up two cylinders 108 and produces compression to stage clip 110, so that 110 pairs of two cylinders of stage clip 108 have a reverse pressure, so that rotating turret 101 has a downward pressure Jing pressure wheel 102 to be applied to suspention group On part 50, so that drawstring 40 has a downward pulling force, meanwhile, drawstring 40 also has a reversal interlocking relay upwards, due to Right section (being the fixing point from roller 52 to frame) of drawstring 40 is fixed in frame, thus, two pulling force downwards upwards It is equal.At left section (from roller 52 to one section of swing span 10) of drawstring 40, due to being connected on swing span 10, and And swing span 10 is not fixed, as long as the torque of the clockwise oscillation of 10 right-hand member of swing span applying, more than swing span 10 The gravity and drive shaft 20 of left end balancing weight 13 rotates clockwise required energy and mechanical friction loss, swing span 10 Can rotate clockwise.The pressure produced due to pressure assembly 100 (includes rotating turret 101, pressure wheel 102 and suspension 50 The gravity of applying) weight and drive shaft 20 that are greater than balancing weight 13 rotates clockwise energy external required for output power What amount and mechanical friction were lost, therefore, 10 right-hand member of swing span has the trend of a clockwise oscillation under the pulling of drawstring 40, by This causes the drawstring 40 of the right and left in roller 52 to occur in that two not reciprocity pulling force upwards, and the right is more than the left side so that There is an anticlockwise revolving force on wheel shaft 51, so that wheel shaft 51 rotates counterclockwise, and move down in rotation and suitable The motion of 51 length direction of wheel shaft, so as to drive 10 clockwise oscillation of swing span, so that 10 left end of swing span is raised, so as to Balancing weight 13 is driven to move up.In the process, as wheel shaft 51 and tapered thread wheel 52 are synchronous connections.Therefore, bore Shape screw thread wheel 52 is also to move down in rotation with wheel shaft 51, and thread groove 521 and pressure in rotation is moved down The contact point of wheel 102 is incrementally increased.It is from the central point of wheel shaft 51 to thread groove 521 and the contact point of pressure wheel 102, meeting Incrementally increase in rotation with moving down, and be equal with height is moved down.That is the central point of wheel shaft 51 is to moving down Move how many, while driving tapered thread wheel 52 in rotation is moved down thread groove 521 is increased with 102 contact point of pressure wheel How much, make rotating turret 101 not move down in the effect of tapered thread wheel 52, the first chimb 1071 is made under the holding of pulley 103 Pressure condition.Thus, pressure assembly 100 (rotating turret 101) can be caused to have a downward pressure to be applied to suspension 50 all the time On, and power source is delivered to Jing drawstrings 40 right-hand member of swing span 10, makes 10 clockwise oscillation of swing span, when driver element run to During Figure 11 states, drawstring 40 draws 45 ° of 10 clockwise oscillation of swing span so that swing span 10 drives master by ratchet mechanism 30 Axle 20 has rotated clockwise 45 °, so that main shaft 20 externally exports power.Main shaft 20 passes through drive sprocket 21, chain simultaneously 104th, sprocket wheel 105 and 106 driving cam 107 of rotating shaft have turned clockwise 90 °.Now, the driver element for being in rear stage starts Into working condition.Meanwhile, the driver element of previous stage is then deactivated state.Driver element continues from Figure 11 to Figure 12 states Operation, during the state from Figure 11 to Figure 12, this driver element is then done work to main shaft 20 jointly with rear stage driver element (being to rotate jointly to do work with previous stage driver element to main shaft 20 from Figure 10 to Figure 11), driver element runs to Figure 12 states When, drawstring 40 is whole to draw 90 ° of 10 clockwise oscillation of swing span, while swing span 10 passes through 30 drive shaft 20 of ratchet mechanism And 90 ° have been turned clockwise, cam 107 has rotated clockwise 180 °.Now, the first chimb 1071 is separated with pulley 103, the Two chimb 1072 tackles pulley 103 separated state, the pressure releases that pressure assembly 100 applies to suspension 50, outstanding The gravity for only having pressure frame 101 and pressure wheel 102 to apply on component 50 is hung, so far, driver element stops doing the rotation of main shaft 20 Work(, driver element complete the process that acting is once rotated to main shaft 20.Now, action of gravity of the swing span 10 in balancing weight 13 It is lower to swing counterclockwise, 10 right-hand member of swing span is raised upwards, move up two drawstrings 40, so as to drive 50 up time of suspension Pin rotates and moves up in rotation and move along 51 length direction of wheel shaft, when operation is to Figure 14 states, drives single Unit revert to original state, as the speed that swing span 10 is swung counterclockwise is slightly larger than the speed that main shaft 20 is rotated clockwise, this When cam 107 be also not rotated to the first chimb 1071 and contact with pulley 103, therefore driver element is rested in Figure 14 states Wait.Due to the unidirectional drive performance of ratchet mechanism 30 during swing span 10 is swung counterclockwise, depart from main shaft 20 and drive Dynamic relation, main shaft 20 drive ratchet 31 to continue to rotate clockwise below under the driving of driver element.Swing span 10 then drives circle 32 counterclockwise of ring 34 and ratchet, the front end of ratchet 32 are slipped over from 31 back of tooth of ratchet.When cam 107 turns to the first chimb 1071 contact with pulley 103 and the left end of rotating turret 101 is stayed pressure when, driver element is again introduced into working condition to main shaft 20 rotate acting, repeat said process.
