The specific embodiment

In order to understand the technical scheme of the utility model better, below through concrete embodiment and combine accompanying drawing at length to explain:

See also Fig. 1 and Fig. 2; A kind of lifting device that is used for large ring of the utility model; Comprise suspension ring 1, a vertical loading board 2, a movable block 3, a 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 used for being connected with the suspension hook of lifting crane;

Vertical loading board 2 is vertical shape setting, and its compartment of terrain, bottom is provided with a upper limit bulge loop 21 and lower limit bulge loop 22; The spacing distance of upper and lower

spacing bulge loop

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 equates with the maximum outside diameter of movable block 3; The lower surface of this upper limit bulge loop 21 also is 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 slides on the vertical loading board 2 and at upper and lower spacing bulge loop 21, between 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 three otic placodes 40 are set on the outer peripheral face of this coupling bush 4 radial equipartition,

Three interior claws 5 are hinged on the lower end of the otic placode 40 of coupling bush 4 respectively through bearing pin, so that the eave tile of three interior claws is positioned at the below of movable block 3;

Be connected the lower end of vertical loading board 2 three trammel beams, 6 horizontal ground and radial equipartition; The telescopic 62 that the fixed link 61 and that every trammel beam 6 is provided with a tapped bore by an outer end is enclosed within the outside of fixed link 61 and axially offers a plurality of knock holees in uniform way constitutes; The inner of fixed link 61 is fixed on the lower end of vertical loading board 2, and fixed link 61 is connected through a screw with telescopic 62, and this screw is inserted in the knock hole of telescopic 62 and screws in the tapped bore of fixed link 61 again; Slip through telescopic 62 makes trammel beam 6 become telescopic rod, can adjust the length of trammel beam 6 according to the internal diameter of ring 9;

Three movable arms 7 are movably connected in the same position of every trammel beam 6 respectively; The lower end of every movable arm 7 has hook 71, and upper axial is offered a plurality of adjustment holes 72 in uniform way and is inclined upwardly equidirectionally and is the shape of cranking arm with hook 71; Every movable arm 7 is hinged through a bearing pin and trammel beam 6 respectively, and this bearing pin is inserted in the knock hole of adjustment hole 72 and trammel beam 6 of movable arm 7, can regulate through a plurality of adjustment holes 72 of movable arm and link up with 71 length;

Three mild steel link chains 8 are connected respectively between the upper end of top and movable arm 7 of otic placode 40 of coupling bush 4 radial equipartition.

The lifting device that the utility model a kind of is used for large ring in use; If want lifting device to be hung in the inner ring of large ring 9; Earlier that the hook 71 of movable arm 7 is outside; Again according to the thickness of ring 9 length through the 72 adjustment hooks 71 of the adjustment hole on the movable arm 7, the Outside Dimensions of the flexible hook 71 with three movable arms 7 of the telescopic 62 through trammel beam 6 is adjusted to the internal diameter of ring 9 adaptive then.After adjusting the relative dimensions of lifting device, move down lifting device, make the hook 71 of movable arm 7 be lower than the lower surface of ring 9, lower limit bulge loop 22 outer peripheral faces of the vertical loading board 2 that the interior claw 5 under this moment coupling bush 4 is in; After the lifting crane lifting; Coupling bush 4 is along with suspension ring 1 rise, and interior claw 5 also rises with coupling bush 4, the eave tile of claw 5 contraction in making and collude the lower end at movable block 3; And carrying in the conical grooves 210 of movable block 3 rising entering upper limit bulge loops 21; At this moment, (judging with mild steel link chain 8 slacknesses) also strained with the rising of coupling bush 4 in the upper end of mild steel link chain 8, and inwardly swing the upper end of pulling activity arm 7; And outwards swing and be hooked in the lower surface of ring 9 of the hook 71 that makes movable arm 7, accomplish lifting with ring 9.Interior claw 5 colludes and is used to prevent that coupling bush 4 from gliding and make hook 61 throw off rings 9 in the lower end of movable block 3.Arrive assigned address and transfer ring 9; Coupling bush 4 is glided just in time drop on the upper surface of upper limit bulge loop 21; Mild steel link chain 8 loosens, and the hook of movable arm 7 71 breaks away from rings 9 (judging with mild steel link chain 8 slacknesses), and the eave tile of claw 5 is positioned at the outer peripheral face of lower limit bulge loop 22 and throws off with movable block 3 in making simultaneously; Movable block 3 freely drops on the upper surface of lower limit bulge loop 22, accomplishes the task that ring 9 lifts another station.

If want lifting device to be hung in the outer ring of large ring 9, earlier with the hook 71 of movable arm 7 to inwardly, repeat above-mentioned method again and accomplish and lift.Accomplish the task that ring 9 lifts another station, only need 1 lifting workman, general workman also can accomplish a task all by oneself after being familiar with.

Those of ordinary skill in the art will be appreciated that; Above embodiment is used for explaining the utility model; And be not the qualification that is used as the utility model; As long as in the connotation scope of the utility model, all will drop in claims scope of the utility model variation, the modification of the above embodiment.
