Fig. 2 is the structural representation of the utility model transmission gear mobile device.
Fig. 3 receives rope setting device structural representation on the utility model loose drum.
1. frames among the figure, 2. main drum, 3. motor, 4. drop-gear box, 5. miniature gears, 6. embedding dental formula clutch, 7. oil cylinder, 8. transmission gear, 9. ring gear, 10. loose drum, 11. receive the rope setting devices, and 12. receive the rope miniature gearss, 13. electromagnetic friction clutch, 14. receive the rope reductor, and 15. receive the rope motor, 16. bearing pin, 17. draw dish, 18. pull bars.
The specific embodiment
As can be seen from Figure 1, a kind of twin drum winch of the utility model, it comprises frame 1, motor 3, drop-gear box 4, main drum 2, loose drum 10 and corresponding brake equipment and gear system etc.Motor 3, drop-gear box 4, main drum 2, loose drum 10 etc. are fixed on the frame 1, and correspondingly are provided with brake equipment.Said gear system comprises miniature gears 5, transmission gear 8, embedding dental formula clutch 6, ring gear 9 etc., motor 3 drives miniature gears 5 by drop-gear box 4 and rotates, miniature gears 5 and transmission gear 8 engagements, the transmission gear 8 that can slide on the main drum axle drives main drum 2 by embedding dental formula clutch 6 and ring gear 9 respectively and loose drum 10 rotates, relation between above-mentioned composition structure and parts, and the effect of parts belongs to prior art, no longer describes in detail.
The utility model is realized and improves the work conversion of winch by the transmission gear mobile device on the basis of traditional twin drum winch structure.Fig. 2 is the structural representation of transmission gear mobile device.As can be seen from Figure 2, be fixed with several pull bars 18 around the main drum axle on the transmission gear 8, pull bar 18 outer ends connect one and draw dish 17, draw dish 17 to captive joint with oil cylinder 7 cylinder bars, oil cylinder 7 cylinder barrels are fixed on the frame 1, by oil cylinder control transmission gear 8 moving on the main drum axle.Specifically be that oil cylinder 7 cylinder barrels are fixed on the frame 1 by bearing pin 16, its cylinder bar connects mutually with drawing dish 17, draws dish to connect by 4 pull bars 18 and transmission gear 8, and pull bar 18 1 ends are fixed on and draw on the dish 17, and an end is fixed on the transmission gear 8.
From Fig. 1, Fig. 2, it can also be seen that, said embedding dental formula clutch 6 parts of the utility model are fixed on the main drum 2, another part is fixed on the transmission gear 8, when motor 3 runnings, by drop-gear box 4 miniature gears 5 is rotated, when oil cylinder 7 stretches out, promote to be fixed on 4 pull bars that draw on the dish and drive transmission gear 8 and on 2 of main drums, slide, combine main drum 2 work with embedding dental formula clutch 6.When oil cylinder 7 withdrawals, drive transmission gear 8 again the embedding dental formula clutch is separated, main drum is not worked, and transmission gear 8 combines with ring gear 9 again, drives loose drum 10 work.
Also be provided with on the said loose drum 10 of the utility model and receive rope setting device 11, as Fig. 1, shown in Figure 3.Fig. 3 receives rope setting device structural representation on the loose drum.Receiving rope setting device 11 comprises receipts rope motor 15, receipts rope reductor 14, electromagnetic friction clutch 13, receives the miniature gears 12 of restricting, receiving rope motor 15 links to each other with receipts rope reductor 14, electromagnetic friction clutch 13 is fixed on the output shaft of receiving rope reductor 14, can receive the mouth that rope miniature gears 12 is fixed by bolts to electromagnet-friction with ring gear 9 ingears.Whole receipts rope setting device is fixed on the frame 1, is used for controlling the steel rope that tightens up on the loose drum, thus the protection steel rope.Its principle of work is: when steel rope comes loose, receive the rotation of rope reductor by receiving the rope driven by motor, at this moment, electromagnetic friction clutch energising combination, drive receipts rope pinion rotation by electric friction clutch, receive the rope miniature gears and drive ring gear work, rotate, tighten up steel rope thereby drive loose drum.When steel rope tightened up, when pulling force during greater than the friction force of electric friction clutch, electric friction clutch began to skid, receive the rope driven by motor and receive the idle running of rope reductor, thereby the actv. protection receive the rope motor and receive the rope reductor, also actv. has been protected steel rope.
