Abstract
The utility model discloses a hook structure for hoisting heavy objects. The hook structure comprises a hook body (1) and a pulling plate (2), wherein the hook body (1) is in the shape of a 'U'; one end of the hook body (1) is movably connected with the pulling plate (2); a through hole (3) is formed in one end of the pulling plate (2), far away from the hook body (1). By virtue of the adopted structure, the working efficiency can be improved when the heavy objects are hoisted, and meanwhile the hook can be prevented from slipping so as to increase stability and safety during hoisting.
Description
Technical field
The utility model relate to hang carry, the lifting field, specifically be used for the hook structure of hoisting heavy.
Background technology
Hang carry, lifting is the more common a kind of operation of mechanical engineering field, lifting generally needs Current Collector Sleave to coordinate to carry out.Carrying out hanging of weight when carrying, be generally first lifting rope to be tied up on weight, perhaps adopt suspension hook that weight is hooked, then by crane or tower crane, weight is sling, weight is transferred to another place by a place.Adopt above dual mode to carry out weight and hang the problem that has several respects when carrying, if adopt, lifting rope is tied up on weight, have fastness and take off lifting rope than hard problem, not only work efficiency is lower, but also has potential safety hazard; If adopt general suspension hook that weight is hooked, suspension hook landing problem may appear, bring potential safety hazard.
The utility model content
The utility model provides the hook structure that is used for hoisting heavy, when having solved in the past hoisting heavy, exists work efficiency lower, also may bring simultaneously the problem of potential safety hazard.
The utility model is that the technical solution problem is achieved through the following technical solutions: the hook structure that is used for hoisting heavy, comprise coupler body and arm-tie, described coupler body is " U " shape, and an end of coupler body and arm-tie are flexibly connected, and the end away from coupler body on described arm-tie is provided with through hole.When using, lifting rope passes through hole and is connected with arm-tie, coupler body is hooked on weight to be lifted, lifting rope tension arm-tie, the other end of arm-tie is taken advantage of a situation and is snapped in coupler body, under the combined action of coupler body and arm-tie, weight is blocked, as long as lifting rope applies pulling force, coupler body and arm-tie will form gripping mechanism, and pulling force is larger, block tightlyer.
Further, described coupler body caves inward into " U " shape structure with the end that arm-tie is flexibly connected, and arm-tie is positioned at this " U " shape structure, chain connection between coupler body and arm-tie.Arm-tie can freely rotate on coupler body, realizes to greatest extent chucking.
Further, the length of " U " shape structure of the end that described coupler body and arm-tie are flexibly connected is greater than 1/3 of the length of arm-tie, and less than 1/2 of the length of arm-tie.The length of arm-tie is unsuitable excessive or too small, the excessive rotation that is not easy to arm-tie, and the too small easy card of arm-tie that may make is excessive, does not have the effect of chucking.
Further, the inner side end of the described coupler body relative with arm-tie is provided with some the first tread plates.Can prevent from like this between coupler body and weight, skidding occuring.
Further, be parallel to each other between described each first tread plate.
Further, on described arm-tie, the end away from through hole is provided with some the second tread plates.Can prevent from like this between weight and arm-tie, skidding occuring.
Further, be parallel to each other between described each second tread plate.
The utility model compared with prior art has the following advantages and beneficial effect:
(1) the utility model is by the mating reaction of coupler body and arm-tie, with the weight chucking of lifting, and the suffered pulling force of arm-tie is larger, and weight is blocked tightlyer, this mode has avoided well that hook may become flexible, the situation of landing occurs, thereby has guaranteed stationarity and the safety of lifting.
(2) the utility model by on coupler body or arm-tie, tread plate being set, makes weight when contacting with coupler body or arm-tie, is difficult for producing skidding, has further guaranteed the stationarity of lifting, has also strengthened safety simultaneously.

Fig. 1 is the structural representation of embodiment 1 of the present utility model;
Fig. 2 is the structural representation of embodiment 2 of the present utility model;
Fig. 3 is the structural representation of embodiment 3 of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with embodiment, but embodiment of the present utility model is not limited to this.
Embodiment 1:
As shown in Figure 1, the present embodiment comprises coupler body 1 and arm-tie 2, and coupler body 1 is " U " shape, and an end of coupler body 1 and arm-tie 2 are flexibly connected, and the end away from coupler body 1 on described arm-tie 2 is provided with through hole 3.
As preferably, the coupler body 1 of the present embodiment caves inward into " U " shape structure with the end that arm-tie 2 is flexibly connected, and arm-tie 2 is positioned at this " U " shape structure, chain connection between coupler body 1 and arm-tie 2.
In addition, in order to prevent that the arm-tie card is excessive or to rotate inconvenience, the length of " U " shape structure of the end that coupler body 1 and arm-tie 2 are flexibly connected is greater than 1/3 of the length of arm-tie 2, and less than 1/2 of the length of arm-tie 2.
Embodiment 2:
As shown in Figure 2, the present embodiment is substantially the same manner as Example 1, and different places are, the inner side end of the described coupler body 1 relative with arm-tie 2 of the present embodiment is provided with some the first tread plates 4, as preferably, is parallel to each other between each of the present embodiment the first tread plate 4.
Embodiment 3:
As shown in Figure 3, the present embodiment is substantially the same manner as Example 2, and different places are that the end away from through hole 3 on the arm-tie 2 of the present embodiment is provided with some the second tread plates 5, as preferably, is parallel to each other between each of the present embodiment the second tread plate 5.
The principle of work of the present embodiment: lifting rope is connected with arm-tie 2, and coupler body 1 is hooked on weight, pulls lifting rope that weight is sling, after arm-tie 2 is stressed, snap in coupler body 1, and with coupler body 1 combined action, weight is tightened, after completing lifting, unclamp arm-tie 2, can easily take off coupler body 1.
The utility model is illustrated by above-described embodiment, but should be understood that, above-described embodiment just is used for for example and the purpose of explanation, but not is intended to the utility model is limited in described scope of embodiments.In addition; it will be understood by those skilled in the art that; the utility model is not limited to above-described embodiment, can also make more kinds of variants and modifications according to instruction of the present utility model, and these variants and modifications all drop in the utility model scope required for protection.
