Its head end is equipped with handle wheel 13；Left-right rotary ball-screw 15, by the rotational installation of rolling bearing units 16 on pedestal 1, axis
Parallel with the axis of roller 2, feed screw nut 17 is combined on left-right rotary ball-screw 15, and 17 bottom of feed screw nut passes through sliding rail
Axis direction along left-right rotary ball-screw 15 is slidably mounted on pedestal 1, and 15 one end of left-right rotary ball-screw is equipped with gear
Ⅳ 19；Strut 9, tail end are fixed on feed screw nut 17, and head end is provided with thimble 10, and thimble 10 is located at roller 2
Upper end, the interior axially bored line of thimble 10 and the axis perpendicular of roller 2；Rope end fixed mechanism is set on roller 2, wirerope
It is fixed on roller 2 after thimble 10 by rope end fixed mechanism；The number of teeth of gear II 14 is less than the number of teeth of gear I 8,
Gear II 14 is meshed with gear I 8, and the number of teeth of gear III 18 is less than the number of teeth of gear IV 19, gear III 18 and gear IV
19 are meshed, and when roller 2 is rotated by 360 °, the distance that the rotation driving feed screw nut 17 of left-right rotary ball-screw 15 moves horizontally is big
In the diameter of wirerope.In use, by roller 2 is fixed on by rope end fixed mechanism by one end of the good wirerope of size cut
On, rotating handle wheel 13 drives drive shaft 11 to rotate later, since II 14 opposed gear I 8 of gear is pinion gear, drives
Moving gear I 8 may be implemented amplification torque effect and save manpower when rotating.The rotation of roller 2 winds wirerope on roller 2, by
It drives left-right rotary ball-screw 15 to rotate by meshed gears III 18 and gear IV 19 when drive shaft 11 rotates, and controls
Rotary roll ballscrew 15 is outsourcing standard drive component, is provided with dextrorotation screw thread and derotation screw thread, therefore feed screw nut simultaneously thereon
17 can move in opposite directions automatically when running to one end head, reciprocating operation be realized, since wirerope is across thimble
In 10, and 17 transverse shifting of feed screw nut is greater than the distance of wirerope diameter, therefore thimble 10 when one circle of rotation of roller 2
It drives wirerope to become the winding on roller 2 and becomes transverse shifting, realize that wirerope is uniformly equidistantly wrapped in roller 2 along axial direction, and
It can back and forth wind.Entire auxiliary bobbin winder device can be hoisted at overhead traveling crane after wirerope-winding, thus when roller 2 is anti-

Screw 22 is combined on its lower end in counter sink 21 and is located in threading hole 20.The head end of wirerope passes through after being interspersed in threading hole 20
Tightening screw 22 is fixed screw 22 in threading hole 20 wirerope, since screw 22 is arranged in counter sink 21,
Therefore it will not be protruded from the surface of roller 2, not influence wirerope in the winding on 2 surface of roller.
Further, further include the circumferentially spaced several elastic steel sheets 5 for being set to 2 one end of roller, set on pedestal 1
It is equipped with the convex block 6 to raise upward, when roller 2 rotates, convex block 6 is in contact with each elastic steel sheet 5.When logical rotational handle wheel 13 drives
When dynamic roller 2 rotates, the elastic steel sheet 5 on roller 2 is constantly contacted with convex block 6 when rotated, and elastic steel sheet 5 is contacted with convex block 6
When generate bending deformation, until across being restored again by being realized under elastic reaction after convex block 6 after its bending deformation.That is it rolls
The operating of cylinder 2 needs bending deformation power when elastic steel sheet 5 and convex block 6 being overcome to contact.Wirerope is wound on roller 2 to work as
Back roll 2 will not be rotated freely due to the contact of elastic steel sheet 5 and convex block 6, to will not loosen after wirerope-winding.Into
One step improves the reliability used.
Preferably, hanging ring 7 is respectively arranged at left and right sides of 1 upper end of pedestal.It can be convenient the entire auxiliary of lifting by hanging ring 7
Bobbin winder device hangs position to row, to further improve the convenience used.The left and right ends difference of roller 2 is along the circumferential direction
It is provided with line retaining disk 3, the outer diameter of line retaining disk 3 is greater than the outer diameter of roller 2.Line retaining disk 3 can prevent the cable on roller 2 from roller
It is detached from 2, line retaining disk 3 plays blocking position-limiting action, further improves the reliability that entire auxiliary bobbin winder device uses.
