Abstract
The utility model discloses a heavy hammer type joist steel hoisting clamp, relating to the technical field of hoisting tools. A connecting case body (5) is of hollow cavity structure; an outer drum (12) is fixedly arranged on the upper surface in the connecting case body; an air hole (2) communicated with the outside is arranged at the upper end of the outer drum (12); a plunger (3) is arranged in the outer drum; a gasket ring (4) in sliding fit with the inner wall of the outer drum is arranged at the outer edge of the plunger; the upper end of a push-in and pull-out rod (6) is fixedly connected with the plunger; the lower end of the push-in and pull-out rod is movably hinged with one end of each of the two positioning support poles (7) and the upper end of a heavy hammer (9) through pin rolls (8); the other end of each of the two positioning support poles (7) is movably hinged with the middle part of the inner side of a lifting hook (10); and the upper end of the lifting hook is movably hinged with two sides of the connecting case body (5). The heavy hammer type joist steel hoisting clamp can realize automatic opening and closing, is dispensed with or reduces the process of centering the hoisting clamp by an operator, and is simple in structure and strong in practicability.
Description
[technical field]
The utility model relates to the lifting device technical field, especially relates to a kind of weight hammer type I-beam section hoisting gripping member that utilizes the automatic folding suspension hook of weight.
[background technology]
At present along with fast development of national economy, the use of large-scale steel structure in major project is also more and more, but the lifting for the I-beam section that plays the main support effect is to use steel rope binding lifting basically, since the I-beam section section bar by producer to the construction need repeatedly start shipment, lifting work, lifting each time all exists uses crane with the horizontal or vertical carrying problem of I-beam section, so all must consider each time steel rope binding, disassemble problem, very inconvenience.
[summary of the invention]
For the deficiency in the background technology, the utility model discloses a kind of weight hammer type I-beam section hoisting gripping member, weight hammer type I-beam section hoisting gripping member described in the utility model can be realized automatic folding, need not or the minimizing personnel set upright the operation of hoisting gripping member; And simple in structure, advantage such as practical.
In order to realize the foregoing invention purpose, the utility model by the following technical solutions:
A kind of weight hammer type I-beam section hoisting gripping member, described connect box is a cavity structure, be fixed with urceolus at connect box internal upper part face, described urceolus upper end is provided with and is communicated with exterior pore, in urceolus, be provided with plunger, be provided with seal ring in described plunger outer rim, seal ring and outer tube inner wall bearing fit; Advance, involve bar upper end captive joint plunger, described propelling, an end that involves bar lower end and two location supporting rods and weight upper end are movably hinged by bearing pin, the other end of two location supporting rods and suspension hook middle inside are movably hinged, and described suspension hook upper end is movably hinged with the connect box both sides.
Described weight hammer type I-beam section hoisting gripping member is provided with suspension ring in the casing upper end.
Described weight hammer type I-beam section hoisting gripping member, described suspension hook lower surface are circular-arc gradual bill to suspension hook.
Described weight hammer type I-beam section hoisting gripping member advances, involves bar and plunger is set to one.
Described weight hammer type I-beam section hoisting gripping member, the pore that is arranged on the urceolus upper end is at least one.
Owing to adopted technique scheme, the utlity model has following beneficial effect:
Weight hammer type I-beam section hoisting gripping member described in the utility model, utilize the sealing principle of syringe, make the pore of urceolus upper end under the cooperation of plunger, seal ring and weight, realize the closing speed of slowing down of suspension hook, and because not closing phenomenon can't appear in the effect of weight; Especially adapt to personnel and be inconvenient to arrive operating mode place hoisting gripping member and transfer, lifting; The utility model is simple in structure, and is practical, is easy to large-scale promotion application.
[description of drawings]
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, suspension ring; 2, pore; 3, plunger; 4, seal ring; 5, connect box; 6, advance, involve bar; 7, location supporting rod; 8, bearing pin; 9, weight; 10, suspension hook; 11, I-beam section; 12, urceolus.
[specific embodiment]
With reference to the following examples, can explain the utility model in more detail; But should be noted that the utility model is not limited to following embodiment.
At a kind of weight hammer type I-beam section hoisting gripping member described in Fig. 1, described connect box 5 is a cavity structure, be fixed with urceolus 12 at connect box 5 internal upper part faces, described urceolus 12 upper ends are provided with and are communicated with exterior pore 2, in urceolus 12, be provided with plunger 3, be provided with seal ring 4 in described plunger 3 outer rims, seal ring 4 and urceolus 12 inwall bearing fits; Advance, involve bar 6 upper end captive joint plungers 3, described propelling, an end that involves bar 6 lower ends and two location supporting rods 7 and weight 9 upper ends are movably hinged by bearing pin 8, the other end of two location supporting rods 7 and suspension hook 10 middle inside are movably hinged, and described suspension hook 10 upper ends and connect box 5 both sides are movably hinged.
Described weight hammer type I-beam section hoisting gripping member is provided with suspension ring 1 in casing 5 upper ends; Described suspension hook 10 lower surfaces are circular-arc gradual bill to suspension hook 10; Advance, involve bar 6 and be set to one with plunger 3; The pore 2 that is arranged on urceolus 12 upper ends is at least one.
Implement weight hammer type I-beam section hoisting gripping member described in the utility model, the utility model utilizes the sealing principle of syringe, the pore 2 that makes urceolus 12 upper ends is at plunger 3, that has realized suspension hook 10 under the cooperation of seal ring 4 and weight 9 slows down closing speed " because the effect of weight 9; not closing phenomenon can't occur ", being inconvenient to arrive operating mode place hoisting gripping member personnel transfers, meet I-beam section 11 backs and separate two suspension hooks automatically at suspension hook 10 bottom surfaces circular arcs, can block I-beam section 11 until two suspension hooks, carry described hoisting gripping member slowly, weight 9 whereabouts two suspension hooks 10 just block I-beam section 11, and weight 9 drop-down two location supporting rods 7, force the bill centripetal force of suspension hook 10 to block the both wings of I-beam section 11, but I-beam section 11 is formed just handling I-beam section 11 of locking state; When transferring I-beam section 11 on I-beam section 11 under the effect of described hoisting gripping member deadweight top weight 9, move on the weight 9, described weight 9 is gone up the top simultaneously, make propelling, involve to push away on the bar 6 and make two suspension hooks 10 separately, plunger 3 makes under the effect of seal ring 4 that air effluxes by pore 2 in the urceolus 12, advancing, involve bar 6 and plunger 3 makes in the urceolus 12 under the sealing of seal ring 4 and is in vacuum state, and adsorb plunger 3, so two suspension hooks 10 temporarily can be not closed, the hoisting gripping member of slinging makes two suspension hooks 10 of hoisting gripping member separate with I-beam section 11.
