Stating switching between sliding fortune base portion 622 has the first lead piece 65, is connected with front and rear sides tail at the top of first lead piece 65
Second lead piece 64 of the tip and front and back 62 inner wall of the second hack lever switching improves and turns so that it is regular to make to roll out the hoisting rope come
Receive lifting rope quality.
When original state, third guide block 63 is located at the left-most position in guide groove 43, slides at this point, the first guide block 445 is located at
The right-most position in chamber 44 is transported, the first sliding fortune block 447 for making the first guide block 445 drive rear side is visited completely into passageway slot 441,
Meanwhile the first tapered wheel 4472 on the right side of the first guide block 445 is utmostly visited into the first accommodating chamber 42 and the first tapered wheel
4472 right lateral sides engage connection with the second 423 front left sides of tapered wheel, at this point, the first guide block 445 drives the second sliding fortune block of front side
446 visit in stand in channel chamber 442 completely, meanwhile, the second guide block 466 of sliding 463 left and right sides of fortune block of third is by the first spring coil 462
Pressure on top surface, so that the second guide block 466 is located at the most forward position in the first guide groove 461, meanwhile, make sliding 463 front side of fortune block of third
Oblique sliding portion 4631 be fully located in oblique slot 4461, at this point, 465 maximum journey of inlay card axis of sliding fortune 463 trailing flank of block of third
Degree is far from the caulking groove 4521 in switching casing 452.
When needing to adjust turn receipts lifting rope support distances and turning to receive lifting rope, pass through the drive of the second driving device 4471 first
First tapered 4472 turns of wheel drives the bull stick on the second tapered wheel 423 and the second tapered wheel 423 by the first tapered wheel 4472
421 turns, and then by the worm screw 422 of the drive of bull stick 421 front and rear sides, front and back is then driven by the worm screw 422 of front and rear sides respectively
The worm gear 433 of two sides and 431 turns of the first screw rod on worm gear 433, and then driven respectively by the first screw rod 431 of front and rear sides
Third guide block 63 in front and rear sides guide groove 43 arrives designated position until adjusting, then gradually along the sliding fortune of 43 right direction of guide groove
The second driving device 4471 is controlled to stop turning, at this point, 443 turns of the second screw rod is driven by first driving device 444, meanwhile, by
Second screw rod 443 drives the first guide block 445 gradually along the sliding sliding fortune of fortune 44 left direction of chamber, at this point, the first guide block 445 drives rear side
The first sliding fortune block 447 into sliding 44 left side of fortune chamber sliding fortune gradually slip away in passageway slot 441, meanwhile, the first sliding fortune block 447 drives
First tapered wheel 4472 is detached from the second tapered wheel 423 and is gradually distance from the second tapered wheel 423, at this point, before the first guide block 445 drives
The sliding fortune block 446 of the second of side breaks away fortune to the left, meanwhile, the inclined-plane cunning by the inclined-plane in oblique slot 4461 and in oblique sliding portion 4631
Fortune press cooperation makes the second guide block 466 of sliding 463 left and right sides of fortune block of third gradually overcome the pressure on top surface in the first spring coil 462
It breaks away and transports backward, until when the first guide block 445 as shown in Figure 4 slides the left-most position transported in sliding fortune chamber 44, at this point, first leads
The sliding fortune block 447 of the first of 445 rear side of block is slid completely into sliding fortune chamber 44, meanwhile, the first tapered wheel on the first sliding 447 right side of fortune block
4472 utmostly far from the second tapered wheel 423, at this point, the second sliding fortune block 446 of the front side of the first guide block 445 utmostly visit into
In sliding fortune chamber 44, meanwhile, the trailing flank on 4461 right side of oblique slot and sliding fortune 463 leading flank of block of third are sliding on the second sliding fortune block 446
Fortune is cooperatively connected, at this point, the sliding fortune block 463 of third overcomes the pressure on top surface of the first spring coil 462, keeps sliding 463 rear side of fortune block of third maximum
Degree is visited into the second accommodating chamber 45, meanwhile, visit the inlay card axis 465 of sliding 463 rear side of fortune block of third utmostly into caulking groove
In 4521, at this point, driving 465 turns of inlay card axis by third driving device 464, and then switching casing 452 is driven by inlay card axis 465
And 453 turns of the second transfer wheel on switching 452 outer surface of casing, the is driven by transfer tape 54 in the second transfer wheel 453
One 52 turns of transfer wheel, and then 51 turns of core on the first bull stick 53 and the first bull stick 53 are driven by the first transfer wheel 52, it realizes
Automatic winding.
