Abstract
The utility model relates to a three-chain adjustable sling which comprises a lifting ring, three lifting chains which are arranged on the lifting ring and have the same structure, and an adjusting device arranged at the lower end of the lifting chains, wherein the adjusting device comprises an adjusting sleeve of which the inner side is provided with a thread, an upper nut which is arranged in the upper end of the adjusting sleeve and is fixed with the adjusting sleeve, a lower nut which is arranged in the lower end of the adjusting sleeve and is fixed with the adjusting sleeve, an adjusting bolt which is in threaded connection with the upper nut, and a lifting hook which is in threaded connection with the lower nut; and the other end of the adjusting bolt is connected with the lifting chains. According to the three-chain adjustable sling provided by the utility model, the accurate position of the complex lifted weight is not required to be determined, the three lifting points are outside the center of gravity during lifting, vertical and stable lifting can be realized, and the three-chain adjustable sling is easy to operate, convenient to use, safe and reliable.
Description
Technical field
The utility model relates to a kind of three adjustable suspenders of chain.
Background technology
At present, chain sling, the steel ropes of adopting during hoisting heavy more, because the lifting body form is irregular, center of gravity is difficult to determine, it is larger that lifting position and chain sling, rope capacity are regulated difficulty, and during lifting, object often is difficult to vertically rise and fall not steady, operating difficulties when especially installing and cast the horizontal handling of operating process needs, the vertical takeoff and landing (VTOL) such as (or under) large-scale core at equipment, and have certain potential safety hazard.
The utility model content
Technical problem to be solved in the utility model is to provide adjustable, simple in structure, the easy to use and lifting three high adjustable suspenders of chain of accuracy rate of a kind of chain sling length.
The utility model adopts following technical scheme:
The utility model comprises suspension ring, be arranged on three identical chain slings of structure on suspension ring and the control apparatus that is arranged on the chain sling lower end; Described control apparatus comprises inboard screwed regulating sleeve, be arranged in the regulating sleeve upper end upper nut fixing with regulating sleeve, be arranged on lower nut, the adjusting bolt that is threaded with upper nut of fixing with regulating sleeve in the regulating sleeve lower end and the suspension hook that is threaded with lower nut, and the other end of described adjusting bolt is connected with chain sling.
Upper nut described in the utility model is left-handed nut, and described lower nut is the right handed unt.
The utility model good effect is as follows: the three adjustable suspenders of chain that the utility model proposes, adopt at 3 and decide the face principle, adjust wall scroll chain sling entire length by the rotation tunable arrangement, make simultaneously not stressed in three Heave Heres of sustained height, realize vertical, the quiet takeoff and landing of suspended object, guarantee the horizontal handling of suspended object.The three adjustable suspenders of chain that use the utility model proposes can be determined the accurate location of complicated suspended object center of gravity, and during lifting, vertical, the steady lifting outside center of gravity, just can be realized in three Heave Heres, and simple to operate, esy to use, safe and reliable.
Description of drawings
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is the utility model control apparatus structural representation.
In the accompanying drawings: 1 suspension ring, 2 chain slings, 3 control apparatuss, 4 adjusting bolts, 5 upper nuts, 6 regulating sleeves, 7 lower nuts, 8 suspension hooks.
The specific embodiment
As shown in accompanying drawing 1,2, the utility model comprises suspension ring 1, be arranged on three identical chain slings 2 of structure on suspension ring 1 and the control apparatus that is arranged on the chain sling lower end; Described control apparatus 3 comprises regulating sleeve 6, be arranged in regulating sleeve 6 upper ends with the inboard fixing upper nut 5 of regulating sleeve 6, be arranged in regulating sleeve 6 lower ends lower nut 7, the adjusting bolt 4 that is threaded with upper nut 5 of fixing with regulating sleeve 6 inboards and the suspension hook 8 that is threaded with lower nut 7, the other end of described adjusting bolt 4 is connected with chain sling 2, described upper nut 5 is left-handed nut, and described lower nut 7 is the right handed unt.
As shown in accompanying drawing 1,2, when using the work of the utility model suspender, suspension ring 1 are hung on driving or hoist lifting hook, three suspension hooks 8 are hung on three outer suspension centres of suspended object center of gravity, rotating regulating sleeve 6, make adjusting bolt 4 and suspension hook 8 can screw in simultaneously or screw out regulating sleeve 6, realize the adjusting of three chain sling length; Also shackle hook 8 or adjusting bolt 4 separately, realize length adjustment, three suspension centres are simultaneously stressed when lifting, during lifting, object does not tilt, realize vertically, steadily lifting by crane object, reduced hanging object and collided with, prevented that hanging object from damaging, when installing, casting (or under) large-scale core at equipment, advantage is particularly evident.The three adjustable suspenders of chain that use the utility model proposes can be determined the accurate location of complicated suspended object center of gravity, and during lifting, vertical, the steady lifting outside center of gravity, just can be realized in three Heave Heres, and simple to operate, esy to use, safe and reliable.
Claims (2)
