After the second cam 74 rotates 180 degrees, the first convex edge 741 is separated from the bottom edge of the second weight 63, and the bottom edge of the second weight 63 corresponds to the second convex edge 742 and is in a separated state, so that under the action of the gravity of the second weight 63, the pressure wheel 62 presses down on the suspension assembly 50, the left end of the rotating frame 61 is in a suspended state, so that the pressure assembly 60 has a downward gravity to be applied on the suspension assembly 50, and is transmitted to the right end of the roller 10 through the pull rope 40 to pull the roller 10 to rotate clockwise, thereby driving the first weight 12 to move upward.

So that the second driven gear 94 is rotated clockwise, and the driving gear 25 is rotated counterclockwise due to the engagement of the second driven gear 94 with the driving gear 25, and the main shaft 20 is rotated counterclockwise due to the synchronous coupling of the driving gear 25 with the main shaft 20. The transmission ratio of the transmission mechanism 90 is 1, that is, when the drum 10 rotates clockwise for one turn, the driving gear 25 rotates for one turn when the transmission mechanism 90 transmits the rotation to the first driving gear 25, so that the driving spindle 20 rotates counterclockwise for one turn.

Specifically, referring to fig. 6, the limiting mechanism 80 is installed on the frame, the limiting mechanism 80 is used for limiting the wheel shaft 51 to move only in the vertical direction, specifically, the limiting mechanism 80 is composed of four retaining posts fixed on the frame, each of the four retaining posts is a group of two, each group of retaining posts is composed of a retaining post 81 and a rack 82, the retaining posts 81 are respectively retained on the outer surface of the left wheel shaft 51 at the two ends of the wheel shaft 51, the racks 82 are respectively retained at the right end of the wheel shaft 51 and engaged with the gear 55, so that the gear 55 is engaged with and rotates along the racks 82 when the wheel shaft 51 moves up and down.

taking the case that each driving unit does work on the main shaft 20 once, the roller 10 rotates 360 °, and the transmission ratio between the driving sprocket 21 and the first sprocket 72 is 2 to 1, in the initial state, the driving mechanism is in the position shown in fig. 12, the first flange 741 of the cam 74 contacts with the bottom edge of the second counterweight 63 and jacks up the left end of the rotating frame 61, so that the groove of the pressure wheel 62 is separated from the threaded flange 531 of the threaded wheel 53, and the groove of the pressure wheel 62 is located at the highest position of the threaded flange 531 of the threaded wheel 53, the suspension assembly 50 is located at the lowest position, and the right end of the roller 10 only has the weight of the suspension assembly 50 applied by the pull rope 40. At this time, the gravity of the first counter weight 12 of the left driving unit of the drum 10 is greater than the pulling force of the pulling rope 40 to the right end of the drum 10 and the energy of the mechanical friction loss and the weight required for driving the rotation of the main shaft 20 when the drum 10 rotates counterclockwise, so that the left end of the drum 10 rotates counterclockwise under the action of the gravity of the first counter weight 12, the main shaft 20 is driven to rotate counterclockwise by the second ratchet mechanism, and the main shaft 20 outputs power to the outside. When the driving mechanism operates to the state shown in fig. 13, the left driving unit first counter weight 12 pulls the drum 10 to rotate 180 ° counterclockwise, and the drum 10 also drives the main shaft 20 to rotate 180 ° counterclockwise through the second ratchet mechanism, so that the transmission ratio of the driving sprocket 21 to the first sprocket 72 is 2: 1, so that the main shaft 20 drives the cam 74 to rotate 90 ° counterclockwise through the driving sprocket 21, the chain 71, the first sprocket 72 and the rotating shaft 73, and at this time, one driving unit of the second group of driving mechanisms enters the working state and one driving unit exits the working state. The driving unit continues to operate in fig. 14, and when the first counter weight 12 moves down to the state of fig. 14, the drum 10 rotates 360 ° all the way, and at the same time, the drum 10 drives the main shaft 20 to rotate 360 ° through the second ratchet mechanism, and the cam 74 rotates 180 °. At this time, the first convex edge 741 is separated from the bottom edge of the second balancing weight 63, and the bottom edge of the second balancing weight 63 corresponds to the second convex edge 742 of the cam 74 and is in a separated state, so that the first balancing weight 12 completes one rotation work applying process to the spindle 20, and the left driving unit of the set of driving mechanisms stops rotating work applying to the spindle 20 and enters a procedure of returning to an initial state. And simultaneously, the right driving unit enters a working state. At this time, the left end of the rotating frame 61 loses the supporting force, so that under the action of the gravity of the second balancing weight 63, the groove of the pressure wheel 62 presses down on the thread flange 531 of the threaded wheel 53, so that the gravity supporting point of the left end of the rotating frame 61 is transferred from the cam 74 to the lowest point of the thread flange 531 of the threaded wheel 53, thereby allowing the pressure assembly 60 to have a downward gravity to transmit the gravity to the right end of the drum 10 through the hanger assembly 50 and the pull string 40, a clockwise rotation force source is applied to the drum 10, and at the same time, the roller 52 rotates counterclockwise by the gravity of the pressure wheel and moves downward in rotation, thereby rotating the drum 10 clockwise, in this process, since the axle 51, the roller 52 and the screw wheel 53 are synchronously coupled, the screw wheel 53 is also moved down as the axle 51 is rotated, and the contact point of the thread flange 531 with the groove of the pressure wheel 62 increases gradually in the rotational downward movement. That is, the contact point between the flange 531 of the threaded wheel 51 and the groove of the pressure wheel 62 increases gradually during the rotation from the center point of the wheel shaft 51 to the downward movement, and the height is the same as the downward movement height, that is, the center point of the wheel shaft 51 moves downward by a certain amount, and the threaded wheel 53 is driven to increase the contact point between the flange 531 of the threaded wheel and the groove of the pressure wheel 62 during the downward movement, so that the left end of the rotating frame 61 does not move downward, and the bottom of the second weight 63 is separated from the second flange 742. Therefore, the pressure assembly 60 always has a downward gravity applied to the suspension assembly 50 and transmitted to the right end of the cylinder 10 through the pull rope 40, so that the cylinder 10 rotates clockwise. Therefore, the ring 34 of the first ratchet mechanism 30 is driven to rotate clockwise, so that the ratchet wheel 31 is driven to rotate by the pawl 32, the ratchet wheel 31 is pivoted on the spindle 20 and is synchronously connected with the driving gear 35, so that the driving gear 35 also rotates clockwise, and because the driving gear 35 is meshed with the first transmission gear 91, the clockwise rotating moment of the drum 10 is converted into the anticlockwise rotating force to be applied to the spindle 20 through the transmission mechanism 90 and the driving gear 25, so as to provide a force source for the rotation of the spindle 20, and meanwhile, when the drum 10 rotates clockwise, the hanging rope 11 is wound to the drum 10, so that the first counterweight block 12 moves upwards. When the driving unit is operated to the state shown in fig. 15, the gravity of the pressure assembly 60 pulls the roller 10 to rotate clockwise by 180 ° through the suspension assembly 50 and the pull rope 40, the roller 10 also drives the main shaft 20 to rotate counterclockwise by 180 ° through the first ratchet mechanism 30 and the transmission mechanism 90, the cam 74 is driven by the main shaft 20 to rotate by 90 °, and at this time, one driving unit in the second group of driving mechanisms is out of the working state and enters the working state. The drive unit continues to operate from fig. 15 to fig. 16, and when the drive unit operates to the state of fig. 16, the gravity of the pressure assembly 60 pulls the drum 10 to rotate clockwise 360 degrees through the suspension assembly 50 and the pull rope 40, the drum 10 also drives the main shaft 20 to rotate counterclockwise 360 degrees through the first ratchet mechanism 30 and the transmission mechanism 90, the cam 74 rotates 180 degrees under the driving of the main shaft 20, at this time, the second convex edge 742 is separated from the bottom edge of the second balancing weight 63, the first convex edge 741 is contacted with the bottom edge of the second balancing weight 63 and jacks up the left end of the rotating frame 61, so that the groove of the pressure wheel 62 is separated from the thread convex edge 531, thereby shifting the downward gravitational support point of pressure assembly 60 from screw wheel 53 to cam 74, thereby, the right driving unit pressure assembly 60 transmits the power source to the right end of the drum 10 through the suspension assembly 50 and the pull rope 40, and the right driving unit finishes the process of applying work to the rotation of the main shaft 20 and enters the initial state program. Meanwhile, the left driving unit returns to the initial state and repeatedly enters the working state to apply work to the rotation of the main shaft 20, and the process is repeated, so that the right driving unit is driven to operate towards the initial state. The cycle is repeated, so that the main shaft 20 can continuously rotate and output power to the outside under the condition that the four driving units of the two groups of driving mechanisms are matched with each other.

When the first convex edge 741 of the cam 74 of each set of driving mechanism contacts with the bottom edge of the second counterweight block 63 and jacks up the left end of the rotating frame 61, so that the groove of the pressure wheel 62 is separated from the thread convex edge 531, another set of driving mechanism is required to cooperate and assist and pay certain energy, and the main shaft 20 can be operated in a repeated cycle working state.

The main shafts 20 of the two groups of driving mechanisms are sequentially arranged along the length direction (namely, the X direction) of the frame and are synchronously connected, the main shaft 20 can be practically arranged as a single main shaft, and the two groups of driving mechanisms share the main shaft 20.

Referring to fig. 8, as a further improvement, in addition to the two sets of driving mechanisms, a set of idle driving mechanism may be provided, when one of the two sets of driving mechanisms fails and needs to be repaired, the set of driving mechanism is suspended, and the idle driving mechanism is started, so that the failed driving mechanism can be repaired without stopping the whole machine. The specific implementation mode is as follows: the chain wheel 72 is provided with an inner octagonal body 721, the end of the rotating shaft 73 is arranged as an octahedron, the octahedron of the rotating shaft 73 can be inserted into the inner octagonal body 721 of the chain wheel 72, meanwhile, the upper edge of the octagonal body 721 in the chain wheel 72 is provided with a screw hole (not marked in the figure), a screw 722 is arranged in the screw hole, and the screw 722 can abut against one surface of the octahedron of the rotating shaft 72, so that the rotating shaft 73 and the chain wheel 72 realize a fixed relationship; when a driving unit needs to be overhauled and maintained, the screw 722 is loosened, the chain wheel 72 is withdrawn from the octahedron of the rotating shaft 73, then the rotating shaft 73 of the idle driving mechanism is adjusted, the angle of the cam 74 of the idle driving mechanism is consistent with the phase of the pause driving mechanism, then the first chain wheel 72 is installed back to the rotating shaft 73 octahedron, the screw 722 is screwed and fixed, the positioning column 223 on the clutch plate 22 of the idle driving mechanism is pushed into the positioning hole 211 of the driving chain wheel 21, the idle driving mechanism can be started, then the clutch plate 22 of the driving mechanism needing to be overhauled is pushed away from the driving chain wheel 21 through the pull rod 24, the positioning column 223 is withdrawn from the positioning hole 211, the pause driving mechanism needing to be overhauled can be completed, and the idle driving mechanism can be used as a new idle driving mechanism after overhauling, and used for replacing a new.

In summary, the present invention utilizes the gravity of the left driving unit first weight 12 applying counterclockwise rotation to the left end of the drum 10 to rotate the drum 10 counterclockwise, and applies a torque to the spindle 20 through the second ratchet mechanism to provide a rotational force source for the spindle 20. The gravity of the right driving unit pressure assembly 60 is transmitted through the suspension assembly 50 and the pull rope 40 to be applied to the right end of the drum 10 to pull the drum 10 to rotate clockwise, the clockwise rotating force is converted into the counterclockwise rotating force which is applied to the main shaft 20 through the first ratchet mechanism 30 and the transmission mechanism 90, and the counterclockwise rotating force is applied to the main shaft 20, so that a rotating force source is provided for the main shaft 20, and therefore, under the mutual cooperation of the four driving units of the two groups of driving mechanisms, the invention can rotate repeatedly, and the main shaft 20 can continuously rotate under the condition of no other power or less other power, so that the power is output outwards. Therefore, the invention can reduce the consumption of energy sources such as coal, gasoline, natural gas and the like, does not discharge harmful substances to the atmospheric environment and reduces the environmental pollution.
