In present embodiment, the manipulator 4 of the present apparatus is mounted on two-way lead screw 31, can be driven by spindle motor 3 and on
Lower movement.Also, because of the characteristic of two-way lead screw 31, can move to or lower limit point after, start reversely to transport
It is dynamic, to realize up and down reciprocatingly shuttling movement.
In present embodiment, when manipulator 4 moves from the bottom up, the first limitation module 12 is needed to clamp nettle
11, the second limitation module 14 unclamps nettle 11, and main drum 1 stops operating, and such manipulator can be at tuning wheel (15)
Nettle is pulled back;When manipulator 4 moves from top to bottom, then on the contrary, the first limitation module 12 is needed to unclamp nettle
11, the second limitation module 14 clamps nettle 11, and main drum 1 starts turning take-up, and such main drum 1 can pull machinery
Nettle back is wound up.
In present embodiment, conductive sheet 441 is pressed on the first contact 72a and the second contact 72 ' instantly, so that the first contact
72a and when the circuit communication of the second contact 72 ', cylinder 43 is started to work, and driving gripping block 422 is mobile, to cooperate limiting section
421 pairs of nettles are clamped.
In present embodiment, when the third contact 54 is connected by upper conductive sheet 451 with 54 ' circuit of the 4th contact,
Then cylinder 43 drives gripping block 422 back to move, and unclamps nettle 11.
In present embodiment, the present apparatus clamps nettle 11 by setting limiting section 421 and gripping block 422.In limiting section
421 lateral surface is provided with inclined surface 4211.When manipulator 4 is rotated with mounting disc, nettle 11 and limiting section 421
It is in contact, this inclined surface 4211 can produce the effect of guiding, so that nettle 11 smoothly enters limiting section 421 and folder
Clamped position between tight block 422.It is then provided with the inner concave 4212 of arc in the medial surface of limiting section 421, in gripping block 422
On then be provided with limited block 423 outstanding;Cooperate limited block 423 by inner concave 4212, nettle can be prevented to be detached from.
In present embodiment, the first limitation module 12 of the present apparatus is transportable, so that nettle 11 can be equal
It is wound on main drum 1 evenly.The movement of first cylinder 2 is driven by auxiliary-motor 72.The output end of auxiliary-motor 72 is connected to secondary two-way
Lead screw, then matching pair feed screw nut, it is ensured that the first cylinder 2 can restore after being moved to extreme position to original
Position, iterative motion.Another of first limitation module 12 acts on exactly after manipulator 4 moves to minimum point, by
During gradually rising, nettle 11 is clamped.
In present embodiment, when needs first, which limit module 12, realizes clamping restriction effect, as long as to the first electromagnet
23 are powered, and the first electromagnet 23 attracts first permanent magnet 221 to move down so that the idler wheel is pressed in institute after being powered
The upper end of the first cylinder 2 is stated, to realize the effect for clamping nettle 11.Specifically, it is exactly moved to most in manipulator 4
When low spot is begun to move up, manipulator 4 makes lower conductive sheet 441 be pressed in the first contact 72a and the second contact at this time
On 72 ', so that the circuit communication of the first contact 72a and the second contact 72 ', the electricity of the first permanent magnet 221 is connected at this time,
At the same time, the electricity of the second permanent magnet 621 is just disconnected.And the circuit of main motor is disconnected, so that main drum 1 stops operating.
In present embodiment, the effect of the second limitation module 14 first is that after manipulator 4 moves to highest point, gradually under
During drop, nettle 11 is clamped;Second is that adjusting the direction from the nettle 11 of tuning wheel 15, enable manipulator 4 smooth
Grab nettle 11.It is provided with the second pressure-bearing spring 65, pointer 621 and graduated scale 661 in the second limitation module 14, in work
When can intuitively embody spring by compression generate elastic force be how many, thus smoothly acquisition nettle 11 on power be more
It is few.In this way, can be avoided nettle 1 drawn it is bad, when pointer 621 points to the dangerous numerical value on graduated scale 661 fastly, should
Stop drag nettle 11.
In present embodiment, when needs second, which limit module 14, realizes clamping restriction effect, as long as to the second electromagnet
63 are powered, and the second electromagnet 63 attracts second permanent magnet 621 to move down so that the idler wheel is pressed in institute after being powered
The upper end of the second cylinder 6 is stated, to realize the effect for clamping nettle 11.Specifically, exactly when manipulator 4 moves to most
High point and when start to move down, manipulator 4 makes conductive sheet 451 by the third contact 54 and the 4th touching at this time
54 ' circuits of point are connected, and electromagnet 63 is powered at this time, and at the same time, the electricity of the first permanent magnet 221 is just disconnected.And start
The circuit of main motor enables main drum 1 to rotate beginning take-up.
In present embodiment, the present invention, which can show, recycles one section for nettle, then carries out last recycling by main drum again,
So as to protect winch, especially protection drive mechanism, extend the service life of winch.
Protection scope of the present invention includes but is not limited to embodiment of above, and protection scope of the present invention is with claims
Subject to, replacement, deformation, the improvement that those skilled in the art that any pair of this technology is made is readily apparent that each fall within the present invention
Protection scope.
