Please refer to and pushed up described in Fig. 8, Fig. 9 power component 70 including sprocket wheel 72 through the synchronous cam 74 for coupling of rotating shaft 73, and Sprocket wheel 72 extends to the second balancing weight 63 and is provided with phase by the connection synchronous with drive sprocket 21 of chain 71, the cam 74 through rotating shaft 73 To smooth bottom, the cam 74 is provided with the first chimb 741 and the second chimb 742, and the first chimb 741 is higher than the second chimb 742.And the first chimb 741 contacts the anglec of rotation with the second balancing weight 63 more than 180 degree, and the reply of the second chimb 742 second is matched somebody with somebody The anglec of rotation of pouring weight 63 is less than 180 degree, thus may be such that two driver elements have a mistake for rotating acting to main shaft 20 simultaneously Journey.Specifically, dynamic drive sprocket 21 is rotated, due to cam by chain 71 under the rotation that main shaft 20 drives with movable sprocket 72 74, through the connection synchronous with sprocket wheel 72 of rotating shaft 73, make the synchronous axial system of cam 74, so that the cam 74 under the drive of main shaft 20 First chimb 741 contacts the left end for rotating simultaneously jack-up rotating turret 61 with the bottom of the second balancing weight 63 so that pressure wheel 62 and screw thread Groove 531 is separated, and the right applying of roller 10 is rotated clockwise by suspension 50 and drawstring 40 with pressure relief group 60 Power source so that the left end of roller 10 is rotated counterclockwise under the Action of Gravity Field of the first balancing weight 12, and is applied by ratchet mechanism 30 Main shaft 20 is added on, power source is provided for main shaft 20 is rotated, while drawstring 40 is wound to roller 10 when roller 10 is rotated counterclockwise, Thus drive suspension 50 rotate clockwise, and moved up in rotation and along wheel shaft 51 length direction move, After cam 74 rotates 180 °, rear stage driver element initially enters working condition, two driver elements is had one together When to main shaft 20 rotate acting process, after cam 74 is turned to more than 180 degree, after the first chimb 741 is separated with pulley 65, The second chimb 742 is tackled in the bottom of pulley 65, and the left end of rotating turret 61 loses support force so that in the Action of Gravity Field of the second balancing weight 63 Under, the thread groove 531 of tapered thread wheel 53 is pressed under pressure wheel 62 so that the left end support point of rotating turret 61 be transferred to it is outstanding Hang on component 50 so that pressure assembly 60 has a downward gravity to be applied to roller 10 by suspension 50 and drawstring 40 Right-hand member, rotates clockwise roller 10 so that lifting rope 11 winds to roller 10 and then drives the first balancing weight 12 to move up, Gravity is provided for driver element returns original state.

Please it is installed in frame referring particularly to position-limit mechanism 80 described in Fig. 6 a, Fig. 6 b, the position-limit mechanism 80 is used to limit takes turns Axle 51 is only moved in above-below direction and along the length direction of wheel shaft 51, and the minimum point that wheel shaft 51 is moved down, specifically, position restrainer Structure 80 is made up of four bumping posts being fixed in frame, four one group two-by-two of bumping posts, and two groups of bumping posts difference blockings are in 51 liang of wheel shaft The external peripheral surface at end, every group shelves post bottom be provided with connector, the setting make wheel shaft 51 can only above-below direction and along The length direction of wheel shaft 51 is moved, and the minimum point that wheel shaft 51 is moved down can only be moved down at connector, specifically, in roller 10 when being rotated clockwise, and main shaft 20 is then rotated counterclockwise, due to the unidirectional drive performance of ratchet mechanism 30, now, roller 10 depart from driving relationship with main shaft 20, and due to no interaction relation, roller 10 is extremely difficult to same with main shaft 20 when rotating clockwise Step, that is to say, that when the first chimb 741 of cam 74 contacts jack-up 61 left end of pivoted frame with the second balancing weight 63, driver element It is difficult to keeping synchronous is returned to set position, excessively it is slow it is too fast all to will appear from two driver elements uncoordinated, will eventually stop Only operate, therefore, speed when roller 10 is rotated clockwise is greater than the speed of the rotate counterclockwise of main shaft 20, makes pressure assembly 60 Drive driver element to be returned to initial position in advance, moved down into wheel shaft 51 and no longer moved at connector, driver element is rested on Setting position waits and enters work.

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

Wherein, Figure 11 is to initially enter working state schematic representation, Figure 12 and Figure 13 be at driver element in working order in, To exit in working condition, Figure 15 is in recurrence original state, Figure 16 repeats Figure 14 for driver element revert to original state Enter working condition intention, two cams of driver element 74 are in the staggered installation in 180 degree angle.So that the first driver element is in During Figure 11 states, the second driver element is then in Figure 13 states, and it is right to cause that the second driver element in Figure 13 states is in Main shaft 20 is rotated in the middle of acting.So that the present invention has 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, Make main shaft 20 with the relation that drive sprocket 21 is synchronous connection；

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

Work(haulage drum 10 is done to main shaft 20 with driver element and rotates 380 degree, cam 74 rotates 190 degree, and first is convex Side 741 contacts 190 degree of the anglec of rotation with the second balancing weight 63, and reply the second balancing weight 63 anglec of rotation of the second chimb 742 is 170 As a example by degree, during original state, main shaft 20 is rotated counterclockwise through chain 71 by drive sprocket 21 with movable sprocket 72, and sprocket wheel 72 is through turning Axle 73 is rotated counterclockwise with moving cam 74, and the first chimb 741 and the second balancing weight 63 for making cam 74 are contacted and jack-up rotating turret 61 left ends so that there was only the gravity that suspension 50 applies through drawstring 40 in the right-hand member of roller 10, so that the left end of roller 10 Rotated counterclockwise under the Action of Gravity Field of the first balancing weight 12, and main shaft 20 is transmitted to by ratchet mechanism 30, be 20 turns of main shaft It is dynamic that power source is provided.When driver element is run to Figure 13 states, the haulage drum 10 of the first balancing weight 12 has rotated counterclockwise 360 Degree, roller 10 has rotated counterclockwise 360 degree by the drive shaft 20 of ratchet mechanism 30, and main shaft 20 is driven convex by drive sprocket 21 Wheel 74 has rotated counterclockwise 180 degree, is now in rear stage driver element and initially enters working condition, and driver element continues from figure 13 run to Figure 14 states, and during the state from Figure 13 to Figure 14 is run, this driver element is total to rear stage driver element Done work with being rotated to main shaft 20, when driver element is run to Figure 14 states, the haulage drum 10 of the first balancing weight 12 turns counterclockwise 380 degree are moved, roller 10 has rotated counterclockwise 380 degree by the drive shaft 20 of ratchet mechanism 30, and cam 74 have rotated 190 degree, So far, the first chimb 741 is separated with the bottom of the second balancing weight 63, and the second chimb 742 tackles the bottom of the second balancing weight 63, is rotated The left end of frame 61 loses support force so that under the Action of Gravity Field of the second balancing weight 63, tapered thread wheel 53 is pressed under pressure wheel 62 Thread groove 531 on so that the Gravity support point of the left end of rotating turret 61 from cam 74 be transferred to middle part pressure wheel 62 by Suspension 50 as the strong point, the separated state of the second chimb 742 and the bottom of the second balancing weight 63, so that pressure assembly 60 have a downward gravity to be applied to the right-hand member that suspension 50 is transferred to roller 10 through drawstring 40.So far two drives are completed Moving cell alternately rotates acting program to main shaft 20, and main shaft 20 continues to rotate counterclockwise under the driving of rear stage driver element, Previous stage driver element stops that the rotation of main shaft 20 is done work and entered to return original state program, simultaneously as pressure wheel 62 is The middle part between the second balancing weight of left end 63 of rotating turret 61 and the right-hand member pivoting point of rotating turret 61 is articulated in, therefore, now pressure group Part 60 is applied with the gravity that twice cam 74 is born to suspension 50, that is, when cam 74 bears institute's gravity for G, The gravity that now suspension 50 is born is two G.Thus including suspension 50 gravity, roller 52 the right and left all A downward pulling force more than a G is applied with to drawstring 40 (because cam 74 bears weight of institute's gravity not comprising suspension 50 Power), while drawstring 40 also has a upward reversal interlocking relay, right section due to drawstring 40 is fixed in frame, thus, two to Upward pulling force is equal down.At left section of drawstring 40, due to being connected on roller 10, and roller 10 is not fixed Motionless, as long as the pulling force that rotates clockwise that the right-hand member of roller 10 applies is more than the resistance that the first balancing weight of left end 12 is produced, roller Be rotated clockwise by 10, therefore, the right-hand member of roller 10 has the trend for rotating clockwise under the pulling of drawstring 40, thus So that the drawstring 40 in the right and left of roller 52 occurs in that two not reciprocity upward pulling force, the right is more than the left side so that Have an anticlockwise revolving force on roller 52 so that the counterclockwise of roller 52, and moved down in rotation and along The length direction of wheel shaft 51 is moved, so that drive roller 10 to rotate clockwise, so that lifting rope 11 winds to roller 10, and so that band Dynamic first balancing weight 12 is moved up.In the process, because roller 52, wheel shaft 51 and tapered thread wheel 53 are synchronous connections 's.Therefore, tapered thread wheel 53 is also as wheel shaft 51 and roller 52 are moved down in rotation, and in rotation is moved down Thread groove 531 is incrementally increased with the contact point of pressure wheel 62.It is from the central point of wheel shaft 51 to thread groove 531 and pressure The contact point of wheel 62, can incrementally increase, and be equal with height is moved down with moving down in rotation.That is, wheel shaft 51 central point is moved downwardly how many, while drive tapered thread wheel 53 makes thread groove 531 and pressure in rotation is moved down Take turns 62 contact points increase how many, rotating turret 61 is not moved down in the presence of tapered thread wheel 53, make the second chimb 742 Released state is kept with the bottom of the second balancing weight 63.Thus, may be such that pressure assembly 60 has a downward gravity to apply all the time On suspension 50, and power source is delivered to the right-hand member of roller 10 through drawstring 40, rotates clockwise roller 10, so that hanging Rope 11 winds to roller 10, thus drives the first balancing weight 12 to move up, and is driven when wheel shaft is moved downward to connector single Unit revert to initial position, because the speed that roller 10 is rotated clockwise is more than the speed for rotating counterclockwise, cam 74 now Also it is not rotated to the first chimb 741 and the left end of jack-up rotating turret 61 is contacted with the second balancing weight bottom, therefore driver element is stopped Waited in the position of setting.Due to the unidirectional drive performance of ratchet mechanism 30 in reseting procedure, roller 10 takes off with main shaft 20 Ratchet 31 is driven to continue to rotate counterclockwise from driving relationship, under the driving of the driver element below of main shaft 20.Roller 10 then
