The tension is transmitted to the third clutch pulley and the fourth clutch pulley, respectively, which serve as the operating points of the final power transmission of the second power transmission unit, thereby causing them to rotate.

At this time, the second throttle pulley and the third throttle pulley making a connection to each of the second connecting wire and the third connecting wire respectively control the lifting of the elevating member that moves according to the lifting of the seventh moving pulley and the eighth moving pulley.

On the other hand, the operation of the power transmission device according to the present invention having the above-described configuration is as follows.

First, the hydraulic power supply unit 10 supplies hydraulic pressure or pneumatic pressure, and is controlled through the solenoid valve 13 to supply the first cylinder 11 and the second cylinder 12 sequentially up and down.

In addition, the first pulley connecting line 41 and the second pulley connecting line 42 connected thereto by the sequential vertical operation of the first cylinder 11 and the second cylinder 12 alternately pull and release the first The pulley 40a and the second pulley 40b are moved to alternately raise and lower the first pulley 40a and the second pulley 40b.

By the repetitive lifting operation of the first pulley 40a and the second pulley 40b, a pair of the first half gear rotary body 71 and the second half gear rotation through the power transmission connecting wheel 50. Rotational power can be continuously transmitted to the whole 72.

That is, the third pulley connecting line 60 is pushed and pulled by the interaction of the first moving pulley 40a and the second moving pulley 40b, and the first and second one-way wheels of the power transmission connecting wheel part 50 52, 53 to have a one-way rotation, and through the shaft 51, to drive the rotational power to the rotating shaft 73 to the drive pulley 74 and the driven pulley 75.

Accordingly, the first half gear rotary body 71 having the anti-gear teeth and the second half gear rotary body 72 having the semi-gear teeth arranged in the opposite direction are continuously rotated in one counterclockwise direction.

As a result, the first rotation body 81 having the gear tooth portion 81a engaged with the first half gear rotation body 71 having the half gear teeth rotates together, and the non-engagement state is maintained at the portion without the gear teeth. When the rotation operation is stopped, the second rotating body 82 having the gear tooth portion 82a forming the engagement structure with the second half gear rotating body 82 having the semi-gear teeth is engaged in the initial non-engaged state. To rotate together.

At this time, the first half gear rotor 71 rotates continuously in the counterclockwise direction, and the second pulley connecting line 312 is rotated while the second rotor 82 opposite to the first rotor 81 rotates. Since the first rotating body 81 rotates in reverse, the first half gear rotating body 71 is engaged with the first rotating body 81 and rotates while pulling the fourth pulley connecting line 311. The whole 82 is reversed.

That is, the operation is continuously repeated while supplying hydraulic pressure or pneumatic pressure from the power source supply unit 10 to alternately drive up and down the first cylinder 11 and the second cylinder 12, and the first half gear rotating body ( 71) and the second half gear rotor 72 are alternately formed with the first and second rotors 81 and the second rotor 82, which are matched and connected to each other, to form a state of rotation and reverse rotation.

Thus, when the power by the repetitive lifting operation of the third moving pulley 301 and the fourth moving pulley 302 is applied to the drive string 340, the power is the third one-way wheel 321 and the fourth one direction Alternately acts on the wheel 322.

Herein, the gear unit 130 may include a main gear 131, a first pulley gear 132, and a second pulley gear 134.

At this time, the main gear 131 is rotated in connection with the power supply member (S), made of a configuration having a tooth 131a along the half of the circumference, the power supply member (S) described above is a conventional motor Or the like.

In addition, the first pulley gear 132 is provided with teeth 132a engaging with the teeth 131a of the main gear 131 along the circumference to rotate in the forward or reverse direction of the main gear 131 rotation, and the rotation The first pulley pulley (1) which is connected to the fifth moving pulley (110) by the first lifting wire (133) fixed by the first lifting pulley (110) to lift or unwind the first lifting wire (133). 132b) may be configured.

In addition, the second pulley gear 134 is provided with the teeth 134a engaging with the teeth 131a of the main gear 131 on the opposite side of the first pulley gear 132 along the first pulley gear 132. Rotate in the reverse direction of the rotation, and is connected to the sixth pulley 120 by the second lifting wire 135 having one end fixed by the rotation to wind or unwind the second lifting wire 135 to move the sixth pulley ( It may be configured to have a second pulley pulley 134b for elevating the 120.

Here, the first elevating wire 133 and the second elevating wire 135 may be replaced by a conventional chain, etc., it may be applicable to all the shape surface of the string having other mechanical strength.

For example, when the main gear 131 receiving the rotational power from the power supply member S rotates continuously in the counterclockwise direction, the teeth 134a of the second pulley gear 134 are the teeth of the main gear 131. The driving of the second pulley gear 134 is in a stopped state while the gear is not engaged with the 131a, and the teeth 132a of the first pulley gear 132 are the teeth 131a of the main gear 131. ), The first pulley gear 132 is driven to rotate, and the second pulley gear 134 is rotated in the opposite direction of rotation of the first pulley gear 132 by the rotational force of the first pulley gear 132. Will rotate.

Then, when the first pulley gear 132 rotates, the rotation of the first pulley gear 132 stops at the moment when the teeth 132a of the first pulley gear 132 face the circumference where the teeth 131a of the main gear 131 are not formed. At the same time, the teeth 134a of the second pulley gear 134 are engaged with the teeth 131a of the main gear 131 so that the second pulley gear 134 rotates clockwise. The pulley gear 132 rotates in the opposite direction of rotation of the second pulley gear 134.

As such, the main gear 131 having the teeth 131a formed along the circumference thereof continuously rotates in one direction, and the teeth 132a and 134a of the first pulley gear 132 and the second pulley gear 134 are rotated. The first pulley pulley 132b and the second pulley pulley 134b are first lifted wires 133 and second lifted by repeatedly engaging and separating the teeth of the main gear 131 with the teeth 131a. As the wire 134 is wound or unwound, the fifth moving pulley 110 and the sixth moving pulley 120 connected through them are repeatedly made to move up and down corresponding to each other.
