Description

The special hanger and the using method thereof that are used for inner bore of step
One, technical field
The present invention relates to a kind of load and hang apparatus and using method thereof, particularly relate to a kind of special hanger and using method thereof that is used for inner bore of step.
Two, background technology
In production, transportation, usually the object of slinging is to lift by crane with crane hook, but because the lifting object is different, some are bad during directly with the object of suspension hook lifting when running into, and have to object be tied then in lifting earlier with steel rope or other rope.Because the weight of lifting object is all bigger, bundlees more bothersomely, when especially running into some hollow workpiece or object, suspender mono-problem just seems very outstanding.In order to address the above problem, mentioned a kind of Hook used for inner hole in the utility model patent of Chinese patent 91224729.0, the hook of this suspension hook is outer crotch, at least the 3 pairs of hangers that can be rigidly connected on the suspension ring hang and corresponding with hanger on the pawl fulcrum frame 3 pairs of journal stirrups can be set at least, and every pair of hanger connects with connecting rod one end is movable, the other end of connecting rod hangs the pawl activity with curved boom and connects, the fulcrum that curved boom hangs pawl is movably connected on the journal stirrup that hangs pawl fulcrum frame, can address the above problem, but its structure more complicated.
Producing twister, in the factory such as fields such as steel cord, cable, metal filaments, the application of I-beam wheel and general, the mode of existing slinger's character wheel, fork truck tangles the I-beam wheel both sides carrying of accumbency, fork truck damages the up-to-standard product that twines on the I-beam wheel easily like this, brings damage to product.If adopt the endoporus lifting, can avoid the damage that brings thus.
Three, summary of the invention
The objective of the invention is to propose a kind of simple in structure, durable, dexterous special hanger and using method thereof that is used for inner bore of step easily of use.
Content of the present invention is: a kind of special hanger that is used for inner bore of step, contain the suspender body, be provided with connection lifting structure in suspender body weight heart position, described hanging is specially strip, length and described diameter of bore coupling, two ends are the arc that radius of curvature was slightly less than or equaled the radius of described endoporus; Described suspender two ends are provided with the ledge structure with described endoporus coupling, the length of the suspender body on ledge structure top is slightly less than the diameter of described endoporus step choke, and the length of the suspender body of ledge structure bottom is slightly larger than the diameter of described endoporus step choke.
Described connection lifting structure is to be welded on steel loop or the suspension ring that carry for the suspender body on the suspender body or is to be installed in link with holes on the suspender by fastener.
Described ledge structure is two-layer, or is three layers.
The length of getting out of a predicament or an embarrassing situation that described three layers of ledge structure are the adjacent stations stage structure is greater than the length of topping bar.
A kind of using method that is used for the special hanger of inner bore of step, the connection lifting structure on suspender top is connected to the lifting engine by the lifting link, sling described suspender to the oral area top that inner bore of step is arranged, the center that makes the center of described suspender depart from described inner bore of step, fall this suspender then, make the one end tilt to fall in the described inner bore of step earlier, continue whereabouts suspender to suspender and all fall into endoporus, translation lifting engine is positioned on the line of centers of described inner bore of step the lifting link, promote the lifting engine, the ledge structure of suspender and the step of described inner bore of step interlock;
After lifting was finished, Panasonic's lifting engine made described suspender whereabouts certain distance, and translation lifting engine makes and connects the line of centers that lifting part departs from described inner bore of step, and suspender hangs out suspender after tilting.
Described lifting engine be hoisting crane or for fork truck or for the driving.
Described connection lifting structure is to be welded on steel loop or the suspension ring that carry for the suspender body on the suspender body or is to be installed in connection structure with holes on the suspender by fastener.
Described lifting link has been chain sling or lifting rope or has played suspension rod.
Beneficial effect of the present invention
1, simple in structure, good reliability
Whole suspender just has only suspender body and lifting connection structure two parts to form, and between lifting connection structure and the suspender body for one or captive joint, parts and few, integral structure and simply, reliability is very high.
2, durable
Because the ledge structure of this suspender is compared with suspension hook in the past, load-carrying capacity has lifting greatly, and there is not movable part, impact load stress when not existing when slinging to a certain position of suspender, can avoid consequent destruction, and for one or captive joint, can further reduce the destruction of impact load stress between connection structure and the suspender body to suspender.
3, processing and fabricating is simple, and its reason is simple in structure.
4, easy to use, saving human and material resources
Original suspender is that multiple component flexibly connects, and opens after need making it enter endoporus by external force, hangs up the step of endoporus; And the hand-hole of this suspender and portal need be by external force, shirtsleeve operation lifting engine can be realized, only needs crane operation personnel just can finish crane lifting service, does not need other auxilian, has saved manpower, material resources.
