Embodiment
Embodiment is described in detail with reference to the figures above, referring to shown in Fig. 1 and Fig. 2, the composition of rope winding jib is by electric pushrod
1, the motor for driving electric pushrod is variable-frequency motor, can adjust speed, electric pushrod operationally with adapt to different reels and
The lifting velocity of crane and adjust, the electric pushrod is sitting on rope winding jib base 11, and head is provided with running block 2, institute
Stating running block is made up of 4 pulleys, and 4 pulleys are C0, C1, C2, C3 respectively（As shown in Figure 3）, pacify in the pulley
Equipped with pilot sleeve 3, the pilot sleeve is made up of screw mandrel and sleeve, and screw mandrel two has screw thread to be fixed by bolts to assembly pulley
On wallboard, sleeve is enclosed on screw mandrel, and it is to prevent drawstring from interfering the base of running block 2 that it, which is acted on, and rope winding jib base 11 is consolidated with bolt
It is scheduled on trolley frame, the centre of the rope winding jib base 11 and base 8 is equipped with two guide rails 5, and furtherly, guide rail is cylinder
There is screw thread at shape, both ends, and screwed diameter is less than polished rod diameter, and one end of the guide rail is fixed on rope winding jib bottom by nut
On seat, the other end is fixed on base 8 by nut, is equipped with sliding block 4 and another sliding block 6 on guide rail, sliding block 4 and another
Sliding block 6 can be slided on guide rail, and two card rope sling cylinders 9 are housed on each sliding block, and card rope sling cylinder 9 is enclosed on screw rod 10 and passes through spiral shell
Mother is fixed.
The facade of the base 8 is equipped with three leading block groups 7, the leading block group 7 be respectively a0, a1, a2, b0,
b1、b2（As shown in Figure 2）, it act as changing the Impact direction of steel wire rope, the wirerope-winding structure on sliding block 4 is:First
One end of steel wire rope is fixed in the card rope sling cylinder of the left end of sliding block 4, by the pulley a0 in guide wheel group 7 to pulley b0, then is arrived
The C3 of movable pulley, finally on the row's of being fixed on rope base 11, one end of second steel wire rope is fixed on another card rope on sliding block 4
The left end of sleeve, finally it is fixed on base 8 to pulley a1, then to running block C2 by the pulley b1 in guide wheel group 7.

Job description:The motor of the electric pushrod is variable-frequency motor, can adjust speed, the speed of service of such push rod can
Adjust, to adapt to the lifting velocity of different reels and crane, so improve very big versatility.When the steel wire rope on reel
From both sides to centre move when, electric pushrod elongation, steel wire rope a increases journey running block c2 by speedup, then passes through directive wheel a1
To directive wheel b1, the right-hand member of sliding block 4 is finally pulled, sliding block 4 is moved right, meanwhile, the left end steel wire rope b slack ropes of sliding block 4.It is sliding
The movement to the middle mobile drive card rope sling cylinder of screw rod 10 and 9. of block 4, makes hoist rope be exactly in two card rope sling cylinders
It is middle.With should electric pushrod elongation when, steel wire rope c14 by speedup increase journey running block c0 to directive wheel a2, finally pull
Another sliding block 6 is mobile to centre, while steel wire rope d15 slack ropes.When the hoist rope of reel is wound into centre, now steel
Cord needs to turn to, from being changed into winding to both ends to mid-wrap.Now, sliding block 4 just touches reversing switch 16, makes electronic
The motor reversal of push rod, push rod shrink, and at this moment steel wire rope b13 and steel wire rope d15 switchs to actively restrict, steel wire rope a12 and steel wire rope
C14 slack ropes, with movable slider 4 and two end motions to rope winding jib respectively of another sliding block 6, so as to guide hoist rope to turn to,
Wound to the both ends of reel.Due to the speed of service of sliding block and the winding translational speed of reel steel wire ropes be it is synchronous, thus
Prevent the hoist rope phenomenon that disorderly row restricts from occurring.
