Fig. 2 is the birds-eye view of the lifting device for large ring of the present invention.
Detailed description of the invention
In order to understand technical scheme of the present invention better, be also described in detail by reference to the accompanying drawings below by specific embodiment:
Refer to Fig. 1 and Fig. 2, a kind of lifting device for large ring of the present invention, comprise suspension ring 1, vertical loading board 2, movable block 3, coupling bush 4, three interior claws, 5, three trammel beams, 6, three movable arms 7 and three mild steel link chains 8, wherein:
Suspension ring 1 are for being connected with the suspension hook of lifting crane;
Vertical loading board 2 is arranged in vertical shape, and its compartment of terrain, bottom arranges a upper limit bulge loop 21 and lower limit bulge loop 22; The spacing distance of upper and lower position limiting convex ring 21,22 should be greater than the thickness of movable block 3; The outer peripheral face of upper limit bulge loop 21 is up-small and down-big circular conical surface, and the maximum outside diameter of this upper limit bulge loop 21 is equal with the maximum outside diameter of movable block 3; The lower surface of this upper limit bulge loop 21 is also provided with the conical grooves 210 with the upper surface shape adaptation of movable block 3;
Movable block 3 is the dish-shaped hollow block that a upper and lower end face is circular conical surface, and it to slide on vertical loading board 2 and between upper and lower position limiting convex ring 21,22;
Coupling bush 4 slides over the middle and upper part of vertical loading board 2 and is fixedly connected on the lower surface of suspension ring 1, and the outer peripheral face of this coupling bush 4 arranges three otic placodes 40 radial equipartition,
Three interior claws 5 respectively by the lower end of hinge at the otic placode 40 of coupling bush 4, with the below making the eave tile of three interior claws be positioned at movable block 3;
Be connected to the lower end of vertical loading board 2 the horizontal ground of three trammel beams 6 and radial equipartition; The fixed link 61 and one that every root trammel beam 6 is provided with a tapped bore by an outer end is enclosed within the outside of fixed link 61 and the telescopic 62 axially offering multiple knock hole is in uniform way formed; The inner of fixed link 61 is fixed on the lower end of vertical loading board 2, and fixed link 61 is connected by a screw with telescopic 62, and this screw is inserted in the tapped bore screwing in fixed link 61 in the knock hole of telescopic 62 again; Trammel beam 6 is made to become telescopic rod by the slip of telescopic 62, can according to the length of the internal diameter adjustment trammel beam 6 of ring 9;
Three movable arms 7 are movably connected in the same position of every root trammel beam 6 respectively; The lower end of the movable arm 7 of every root with hook 71, upper axial offer multiple adjustment hole 72 in uniform way and with hook 71 equidirectional to be inclined upwardly and in cranking arm shape; The movable arm 7 of every root respectively by a bearing pin and trammel beam 6 hinged, this bearing pin is inserted in the adjustment hole 72 of movable arm 7 and the knock hole of trammel beam 6, can be regulated the length of hook 71 by multiple adjustment holes 72 of movable arm;
Three mild steel link chains 8 are connected between the top of the otic placode 40 of coupling bush 4 and the upper end of movable arm 7 respectively radial equipartition.
A kind of lifting device for large ring of the present invention in use, the inner ring of large ring 9 is hung in lifting device, first by outside for the hook 71 of movable arm 7, adjusted the length of hook 71 again according to the thickness of ring 9 by the adjustment hole 72 on movable arm 7, then by the telescopic 62 of trammel beam 6 flexible, the Outside Dimensions of the hook 71 of three movable arms 7 is adjusted to the internal diameter of ring 9 adaptive.After adjusting the relative dimensions of lifting device, move down lifting device, make the lower surface of hook 71 lower than ring 9 of movable arm 7, lower limit bulge loop 22 outer peripheral face of the vertical loading board 2 that the interior claw 5 now under coupling bush 4 is in; When after lifting crane lifting, coupling bush 4 rises along with suspension ring 1, interior claw 5 also rises with coupling bush 4, the eave tile of interior claw 5 is made to shrink and hook in the lower end of movable block 3, and carry movable block 3 and rise and enter in the conical grooves 210 of upper limit bulge loop 21, now, the upper end of mild steel link chain 8 is also strained with the rising of coupling bush 4 (judging with mild steel link chain 8 slackness), the upper end of movable arm 7 is pulled inwardly to swing, and the hook 71 of movable arm 7 is outwards swung and is hooked in the lower surface of ring 9, complete the lifting with ring 9.Interior claw 5 hooks and is used for preventing coupling bush 4 from gliding and making hook 61 throw off ring 9 in the lower end of movable block 3.Arrive assigned address and transfer ring 9, coupling bush 4 is glided and just in time drops on the upper surface of upper limit bulge loop 21, mild steel link chain 8 loosens, the hook 71 of movable arm 7 departs from ring 9 (judging with mild steel link chain 8 slackness), make the eave tile of interior claw 5 be positioned at the outer peripheral face of lower limit bulge loop 22 and throw off with movable block 3 simultaneously, movable block 3 freely drops on the upper surface of lower limit bulge loop 22, completes the task that ring 9 is lifted into another station.
The outer ring of large ring 9 is hung in lifting device, first by the hook 71 of movable arm 7 to inwardly, adjusted the length of hook 71 again by the adjustment hole 72 on movable arm 7 according to the thickness of ring 9, then by the flexible of telescopic 62 of trammel beam 6, the Outside Dimensions of the hook 71 of three movable arms 7 is adjusted to the external diameter adaptation with ring 9, then the remaining step repeating above-mentioned method completes lifting.Complete the task that ring 9 is lifted into another station, only need 1 lifting workman, general workman, after being familiar with, also can accomplish a task all by oneself.
Those of ordinary skill in the art will be appreciated that, above embodiment is only used to the present invention is described, and be not used as limitation of the invention, as long as in spirit of the present invention, all will drop in Claims scope of the present invention the change of the above embodiment, modification.
