Description

Electronic rotation coiled strip clamp

The electronic rotation coiled strip of technical field the utility model clamp belongs to the lifting appliance field of hoisting crane, can be used for lifting by crane coiled strip and other article.

Background technology is present, and the suspender of handling coiled strip has following several form: 1, rely on the friction force (gripping power) between grip finger and the coiled strip to carry out handling.So on the one hand coiled strip there is damage, on the one hand poor reliability.2, coiled strip itself carries a hanging scroll, and suspender hangs two suspension hooks, and suspension hook is hung the hanging scroll handling.This nothing is carried the coiled strip of hanging scroll can't handling, as the coil of strip material.3, adopt C type suspender, C type hook passes the coiled strip endoporus and carries out handling.This method is hung automatically, decoupling device is difficult.

Summary of the invention is in order to overcome the deficiency of existing associated spreader, and it promptly is not to rely on friction force (gripping power) that the utility model provides a kind of, neither rely on to carry hanging scroll handling coiled strip.Be a kind ofly can hang automatically, decoupling device, but the suspender of power rotation.

The technical solution adopted in the utility model is: electronic rotation coiled strip clamp is made up of suspender head I, cylinder 7, switching mechanism II, the III of parallel four-bar system, traversing carriage IV, sees Fig. 1 and Fig. 2.Suspender head I is made up of hanging scroll 1 and electrical motor 26, retarder 27, miniature gears 28, interior ring 6, ball 3, big gear wheel 4 mounted thereto; Big gear wheel 4 usefulness bolts 5 are fixed on the cylinder 7, and interior ring 6 usefulness bolts 2 are fixed on the suspender head I.Miniature gears 28 drives cylinder 7 rotations with big gear wheel 4 engagements;

Traversing carriage IV is contained in the middle part of cylinder 7, and it is made up of four transverse slats parallel to each other 35, hinge 12,13, slide block 32, slider frame 36, nut 23, flange 30 and riser 28; See Fig. 3 and Fig. 4.Nut 19 is fixed on the flange 39 by riser 28 usefulness screws 29, and flange 39 is welded on the transverse slat 35; Slide block 32 usefulness screws 33 are fixed on the slider frame 36, and slider frame 36 usefulness screws 37 are fixed on the transverse slat 35.Traversing carriage IV moves up and down in cylinder 7 along screw rod 11, thereby drives the III of the parallel four-bar system motion that is connected on the traversing carriage IV.

The III of parallel four-bar system is made up of strut 15, mobile jib 18, transverse slat 35 and L type caliper 19; Strut 15 be articulated on the transverse slat 35 by hinge 12 and hinge 16 and L type caliper 19 on.Mobile jib 18 also be articulated on the transverse slat 35 by hinge 13 and hinge 17 and L type caliper 19 on.Pole 21 is articulated on the mobile jib 18 and cylinder 7 of parallel four-bar system by hinge 14 and hinge 20, by being fixed on the L type caliper 19 in the traversing carriage IV drive parallel four-bar system on the nut 23, the coiled strip clamp is opened or closure, also be symmetrically installed with a pair of suspension hook 30 in the outside of cylinder 7, can be used to other article of handling.

Switching mechanism II is contained in the cylinder 7, and switching mechanism II is made up of drive motor 8, drop-gear box 9, coupler 10, screw rod 11, nut 23, top chock 25 and step 22, in nut 23 is contained in traversing carriage IV.See Fig. 4.

The beneficial effects of the utility model are: can electronic rotation make work more convenient, hang, pluck coiled strip automatically, not need people's back work of working; Because adopt the parallel four-bar system, clamp clamp height dimension in the switching process is constant, make operation safer; Can lift by crane coiled strip and also can lift by crane other article, need not change suspender, a tractor serves several purposes; Simple in structure, from heavy and light.

The description of drawings 1-constructional drawing of facing of the present utility model; Fig. 2-side-looking constructional drawing of the present utility model; Fig. 3-A-A view of the present utility model; Fig. 4-B-B view of the present utility model; Fig. 5-C partial enlarged view of the present utility model.

Among the figure: I. suspender head, II. switching mechanism, III. parallel four-bar system, IV. traversing carriage, 1. hanging scroll, 2. bolt, 3. ball, 4. big gear wheel, 5. bolt, 6. in ring, 7. cylinder, 8. drive motor, 9. retarder, 10. coupler, 11. screw rods, 12. hinge, 13. hinges, 14. hinges, 15. struts, 16. hinge, 17. hinges, 18. mobile jibs, 19.L type caliper, 20. hinge, 21. poles, 22. steps, 23. nuts, 24. screw, 25. top chocks, 26. electrical motors, 27. retarders, 28 miniature gearss, 29,30 suspension hooks, 31. connecting panels, 32. slide block, 33. screws, 34. shroudings, 35. transverse slats, 36. slider frame, 37. screws, 38. risers, 39. flange discs.

To be that example explanation is concrete with the accompanying drawing implement the specific embodiment: during use, the suspension hook of hoisting crane is hooked on the hanging scroll 1 of suspender head I (long and short dash line among Fig. 1), insert in the coiled strip endoporus L type caliper 19 bottoms, reaches the purpose of lifting coiled strip.Start the drive motor 26 be installed on the suspender head I through retarder 27, miniature gears 28 is rotated, drive big gear wheel 4.Because big gear wheel 4 is affixed with cylinder 7, so big gear wheel 4 is with cylinder 7 rotations, because pole 21 is articulated on the cylinder 7, step 22 and top chock 25 also are fixed on the cylinder 7, so all with cylinder 7 rotations.

Driving motor 8 and the retarder 9 of switching mechanism II fix as one, and connect together by coupler 10 and screw rod 11, and screw rod 11 is fixed on the cylinder 7 by top chock 25 and step 22.Screw rod 11 rotations, nut 23 moves up and down along screw rod 11, simultaneously, drives traversing carriage IV and moves, thereby drive the parallel four-bar system acting.

Strut 15 in the parallel four-bar system be articulated on the transverse slat 35 by hinge 12 and hinge 16 and L type caliper 19 on.Mobile jib 18 in the parallel four-bar system also is articulated on transverse slat 35 and the L type caliper 19 by hinge 13 and hinge 17.Pole 21 is articulated on the mobile jib 18 and cylinder 7 of parallel four-bar system by hinge 14 and hinge 20, so the parallel four-bar system realizes opening of caliper or closed with moving up and down of traversing carriage IV.Suspension hook 30 is hinged by axle 29 and connecting panel 31, and connecting panel 31 is affixed with cylinder 7.When suspension hook 30 is used to lift by crane other article, hoisting wirerope is directly hung on the suspension hook, just can realize the lifting and the rotation of article.
