Description
Technical field
The present invention relates to lifting device, especially relate to a kind of internal and external stopper flange dedicated lifting hook of regulating.
Background technology
Hoisting crane is widely used in the industries such as commercial production, building industry, goods station, storage, is mainly used to lift by crane various goods.On hoisting crane except engine installation, elevator with steel cable, also have suspension hook.Existing suspension hook series products is mostly single coupler body, only pay close attention to object is sling, to object, whether level is paid attention to not enough, current most of suspension hook can't be realized steadily slinging under the prerequisite that does not increase suspension ring, particularly the object with the internal and external stopper flange can't be sling, can not be well automatically-unhooked, operating personal is brought to inconvenience, safety can't be guaranteed.Suspension hook disclosed by the invention, be applicable to the object of lifting with the internal and external stopper flange, and the scope that can regulate the article size that hangs, the object of can steadily slinging under the prerequisite that does not increase suspension ring, the object that hangs hangs behind destination due to the deadweight principle, hang pawl and unclamp voluntarily, suspension hook disclosed by the invention has lifting convenience, easy operating, the advantage that safety is good.
Summary of the invention
Goal of the invention of the present invention is: for the deficiencies in the prior art, a kind of suspension hook is provided, solve current suspension hook and can steadily sling with the object of internal and external stopper flange under the prerequisite of the suspension ring that do not increase, realize that steadily slinging, hang pawl unclamps, improves safety voluntarily.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
Suspension hook of the present invention, comprise helical disk, movable block, hoisting bracket and hang pawl, is evenly equipped with the above helical orbit in three roads on described helical disk, and described helical orbit is the helical track from the helical disk central part to spiral web section; Described helical disk is provided with the quantity movable block corresponding with helical orbit quantity and hangs pawl, the slide block of wherein being located at movable block one end is matched with on helical orbit, and can slide with respect to helical orbit, the other end of described movable block extend out to outside spiral web section and is connected with the middle part of hanging pawl, the described pawl that hangs can swing with respect to this point of connection, and a plurality of ends of hanging pawl are connected on the hoisting bracket of helical disk top by the lifting chain respectively.
Owing to having adopted said structure, a plurality of claw types that hang become a plurality of lifting points, form a pulsation-free lifting plane, can under the prerequisite that does not increase suspension ring, realize steadily slinging with the object of internal and external stopper flange, the rotating screw dish can be regulated the size of hanging the pawl opening and closing, according to the magnitude range of object, regulated, simple operation is simple, is easy to realize.
The below of described helical disk is provided with adjusting support frame, described adjusting support frame comprises supporting disk and gripping arm, the center of described supporting disk is fixedly connected with the helical disk center, the quantity of described gripping arm is corresponding with helical orbit quantity, and is distributed in the limit section of supporting disk, and described gripping arm extend out to outside helical disk, be equipped with movable block in each gripping arm, described movable block can slide with respect to gripping arm, and while making described helical disk rotation, described movable block can drive and hang pawl with respect to the helical disk central slide.
For three road helical orbits uniform on helical disk, its track is the spiral of Archimedes track, slide block on movable block can be according to the trajectory constant speed movement of track, realizes that movable block drives to hang the pawl opening and closing, according to the magnitude range of object, regulates the size of hanging the pawl opening and closing.
Further, described hang pawl for " J " font with internal and external stopper flange dedicated lifting hook, the described pawl two ends of hanging are divided into corresponding in the same way card inner stopper flange end and card outer stopper flange end, the outer end of described card inner stopper flange end is provided with a through hole, and the described vertical arm that hangs pawl is provided with three through holes; Describedly hang four through holes on pawl and from top to bottom first and the 3rd through hole are divided into to one group, second and the 4th through hole are divided into to another group, the through hole that wherein is positioned at middle part in arbitrary group can be connected with the end of movable block, in this group another through hole can with lift chain and be connected.Adopt " J " font to hang the suspension hook of pawl, the two ends of suspension hook can be changed, transposing is hung the pawl two ends and can be realized the object of slinging with the internal and external stopper flange.
Further, described helical disk center is provided with ringbolt, and described ringbolt is connected the helical disk center with the supporting disk center; Described hoisting bracket is provided with the lifting crotch, and described lifting crotch top is provided with an annulus; One end of described lifting chain is connected on hoisting bracket, and the other end is connected in and hangs on pawl by attaching parts.During hoisting objects, will lift by crane crotch and catch on ringbolt, the loop wheel machine suspension hook of can steadily slinging, after object winches to destination, turned crane descends, and hangs pawl because the deadweight principle is unclamped voluntarily, completes lifting.
Further, be equipped with some the first limiting stoppers supporting in web section, described the first limiting stopper is " T " character form structure, and a plurality of the first limiting stoppers are positioned on the same circumference of supporting disk, and the limit section of helical disk is limited.Adopt the first limiting stopper can limit the helical disk rotation, prevent that the object of chucking from dropping or preventing from regulating the big or small change of hanging the pawl opening and closing.
Further, be provided with some the second limiting stoppers on the end away from the helical disk center of circle in gripping arm, described the second limiting stopper is to hanging pawl and the movable block junction is limited.Adopt the second limiting stopper, prevent that the parts that hang pawl and movable block junction from dropping out, when suspension hook is not worked, take out the second limiting stopper, the parts of fast changeable junction, improve the flexibility of junction.
In sum, owing to having adopted technique scheme, the invention has the beneficial effects as follows:
1, on the helical disk in suspension hook, the three uniform above helical orbits in road are the spiral of Archimedes track, according to the spiral of Archimedes principle, slide block more than three uniform movement and regulate movable block simultaneously and slide on helical orbit, movable block drives and hangs the synchronous opening and closing of pawl, can be regulated according to the magnitude range of hung object.
2, during crane loading, the claw type that hangs more than three becomes a plurality of lifting points, forms a stable lifting plane, and object is more steady in lifting and operational process.The suspension hook disclosed by the invention object of can steadily slinging under the prerequisite that does not increase suspension ring, the object that hangs hangs behind destination due to the deadweight principle, hangs pawl and unclamps voluntarily, has that lifting is convenient, easy operating, the advantage that safety is good.
