Abstract
The utility model relates to a kind of bow shackle, comprise standard bow shackle body and pivot pin, described pivot pin afterbody is provided with at least 2 fixed pin holes, and fixed pin holes circumferentially distributes same, is locked after bow shackle body and pivot pin are threaded connection with fixing pin again.Fixing pin is cotter pin or has flexible R shape safety pin.Fixed pin holes is 2, and its axis is orthogonal.Pivot pin head is provided with the locating shoulder of locating when being connected with bow shackle body, and locating shoulder opposite side establishes eye.Compared with prior art, the beneficial effects of the utility model are: 1) pivot pin afterbody establishes fixing pin, and can fix from different perspectives, connect safe and reliable, convenient, flexible; 2) pivot pin head has eye, need not special tool and detachable, easy to use; 3) changing rope in lifting can be temporary fixed by pivot pin, avoids landing from bow shackle body; 4) be applicable to narrow space and require the occasion of easy accessibility, use safety.
Description
Technical field
The utility model relates to a kind of rigging link, particularly relates to a kind ofly be applicable to small space and require the bow shackle of easy accessibility, use safety.
Background technique
To when having the large-tonnage weight of lifting ear to lift, need, with heavy cover ring protection wire rope, because the shackle of D type cannot penetrate the hole of the collar, therefore can only use bow shackle.The bow shackle of current NBS and international standard has W type and X-type, the pivot pin head of W type shackle has eye, therefore just dismantled and assembled without special tool, but its pivot pin afterbody is just fixed by screw thread and shackle, the possibility loosened is there is, once pivot pin skids off because of thread looseness will cause security incident there being the occasion screw-thread fit of vibrations; X-type shackle after connecting with bolt, the pivot pin at tightening nut rear portion arranges fixing pin, its use safety, but the spanner needing dimension during dismounting, and extremely inconvenient in the occasion dismounting that usage space is narrow and small.
Summary of the invention
The utility model provides a kind of bow shackle, and its pivot pin head has eye, and afterbody establishes fixing pin, need not special tool and detachable, and connect safe and reliable, temporary fixed on shackle body of pivot pin can be realized, be applicable to narrow space and require the occasion of easy accessibility, use safety.
In order to achieve the above object, the utility model realizes by the following technical solutions:
A kind of bow shackle, comprise standard bow shackle body and pivot pin, described pivot pin afterbody is provided with at least 2 fixed pin holes, and fixed pin holes circumferentially distributes same, is locked after bow shackle body and pivot pin are threaded connection with fixing pin again.
Described fixing pin is cotter pin or has flexible R shape safety pin.
Described fixed pin holes is 2, and its axis is orthogonal.
Described pivot pin head is provided with the locating shoulder of locating when being connected with bow shackle body, and locating shoulder opposite side establishes eye.
Compared with prior art, the beneficial effects of the utility model are:
1) pivot pin afterbody establishes fixing pin, and can fix from different perspectives, connects safe and reliable, convenient, flexible;
2) pivot pin head has eye, need not special tool and detachable, easy to use;
3) changing rope in lifting can be temporary fixed by pivot pin, avoids threading off landing from bow shackle body;
4) be applicable to narrow space and require the occasion of easy accessibility, use safety.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the right elevation of Fig. 1.
In figure: 1. bow shackle body 2. pivot pin 21. locating shoulder 22. eye 23. fixed pin holes 3. fixing pin
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
See Fig. 1-Fig. 3, it is structural representation of the present utility model, a kind of bow shackle of the utility model, comprise standard bow shackle body 1 and pivot pin 2, described pivot pin 2 afterbody is provided with at least 2 fixed pin holes 23, and fixed pin holes 23 circumferentially distributes same, be locked with fixing pin 3 again after bow shackle body 1 and pivot pin 2 are threaded connection.
Described fixing pin 3 is for cotter pin or have flexible R shape safety pin.
Described fixed pin holes 23 is 2, and its axis is orthogonal.
Described pivot pin 2 head is provided with the locating shoulder 21 of locating when being connected with bow shackle body 1, and locating shoulder 21 opposite side establishes eye 22.
Shackle is a kind of rigging, is widely used because the little load capacity of its volume is large.Shackle conventional on Domestic market is generally divided into GB, American Standard by production standard, marks three classes day; Wherein American Standard is the most frequently used.Unthreaded hole is established in opening end one end of standard bow shackle body 1, and the other end establishes tapped hole, and the afterbody of pivot pin 2 establishes screw thread, pivot pin 2 from after unthreaded hole one end bow shackle body 1 penetrates by being screwed at the other end.The eye 22 of pivot pin 2 head facilitates rotation to tighten pivot pin 2, and need not use special tool.
A kind of bow shackle of the utility model establishes fixing pin 3 at pivot pin 2 afterbody, prevents from being threaded loosening, makes lifting more safe and reliable.Pivot pin 2 afterbody is same circumferentially establishes at least 2 fixed pin holes 23, its quantity can be 2 ~ 4, easily can realize fixing in all directions of fixing pin 3 like this, be particularly suitable for shackle usage space narrow and small or the occasion of fixing pin 3 cannot be inserted at a certain fixed-direction by field condition restriction.
In shackle working procedure; often there will be after a weight is fallen; original place lifts another weight; or the situation of more change steel rope is needed because Heave Here changes; now; only need pivot pin 2 tapped hole one end from bow shackle body 1 to exit, wire rope is taken out, and then other wire rope is put into just can again lift by crane.But because bow shackle body 1 the other end is unthreaded hole, bearing pin 2 is easy to skid off from unthreaded hole come off, if high-lift operation, not only brings impact to construction, more there is the potential safety hazard of falling object from high altitude.Adopt the utility model, during in case of changed rope, only fixing pin 3 need be taken off, pivot pin 2 is exited from tapped hole one end, and then in the unthreaded hole the other end and bow shackle body 1, fixing pin 3 is fixed on fixed pin holes 23, can realize the temporary fixed of pivot pin 2, flexible and convenient to use, practicability, Security are all very strong.
