Summary of the invention:
Technical matters to be solved by this invention is to overcome existing above-mentioned deficiency in the prior art, and a kind of reasonable in design, simple, laborsaving, the spring suspension hook that little being used to of lifting object damage lifted by crane circular object are provided.
The present invention addresses the above problem the technical scheme that is adopted: this is used to lift by crane the spring suspension hook of circular object, comprise suspension hook, it is characterized in that also being provided with spring, connecting rod, portable bar, hold-fast ring, fagging, pivot shaft, suspension hook and two connecting rods are rotationally connected by same rotating shaft, two connecting rod other ends are rotationally connected with two portable bars respectively, two portable bars are captiveed joint with two hold-fast rings respectively and are constituted two coupler bodies, so that improve the intensity of hook assembly, two coupler bodies relatively rotate connection by pivot shaft, one end of spring is connected with suspension hook, and the other end of spring is connected with pivot shaft.
The present invention also is provided with brace panel, and brace panel is captiveed joint with hook assembly.
Fagging of the present invention is four, and wherein two faggings are installed in the hold-fast ring inner portion, and other two faggings are installed in the inboard of hold-fast ring middle part or position, middle back partially, with support and the clamping that makes things convenient for circular object.
Fagging symmetric transverse of the present invention is installed on the hold-fast ring, and the two ends of fagging exceed the same distance of hold-fast ring.Because the two ends of fagging exceed hold-fast ring, when saving the hold-fast ring material, strengthened the contact surface of fagging and hanging object, improved stability and reliability that fagging is held hanging object tightly, make whole suspension hook and ground contact surface increase simultaneously, it can be laid on the ground evenly.
Anti-sliding sleeve is installed on the fagging of the present invention, and this anti-sliding sleeve is a rubber coating.Can increase friction force thus with anti-skidding, and the rubber material helps to prevent the scratch to metal object.
The arm of force ratio of the movable arm of force of the present invention is 6: 1～5: 1, utilizes lever principle to save the power of holding tightly.
The width of fagging of the present invention is 80 millimeters, and the width of hold-fast ring is 80 millimeters, and the length of fagging is 170 millimeters.
The diameter of hold-fast ring of the present invention is 850 millimeters, and two hold-fast rings open and constitute annulus local time, and the distance of two hold-fast ring heads is 400 millimeters.Make that thus the installation and the lifting of circular object are all very convenient.
Described fagging of the present invention and hold-fast ring are fixedly connected by welding.
The shape of fagging of the present invention can be a cuboid.
Fagging of the present invention cooperates with the hold-fast ring radian.
The present invention can put the hanging object of different-diameter easily, have simple and convenient, effectively laborsaving, anti-skidding, stability and reliability is high, and has reduced the advantages such as wearing and tearing to metal object.
Description of drawings:
Fig. 1 is the structural representation of the embodiment of the invention.
Fig. 2 is two faggings at embodiment of the invention hold-fast ring middle part and the scheme of installation of hold-fast ring.
Fig. 3 is two faggings of embodiment of the invention hold-fast ring head and the scheme of installation of hold-fast ring.
The specific embodiment:
Referring to Fig. 1～Fig. 3, the spring suspension hook that the embodiment of the invention is used to lift by crane circular object is provided with suspension hook 1, spring 2, connecting rod 3, portable bar 4, brace panel 5, hold-fast ring 6, fagging 7, suspension hook 1 and two connecting rods 3 are rotationally connected by same rotating shaft, the other end of two connecting rods 3 is rotationally connected with two portable bars 4 respectively, two portable bars 4 fuse with two hold-fast rings 6 respectively and constitute two coupler bodies, each coupler body is provided with brace panel 5, so that improve the intensity of hook assembly, two coupler bodies relatively rotate connection by pivot shaft 8, one end of spring 2 is connected with suspension hook 1, the other end of spring 2 is connected with pivot shaft 8, fagging 7 symmetric transverse are installed on the hold-fast ring 6, the two ends of fagging 7 exceed the same distance of hold-fast ring 6, are used for holding tightly the hanging object that supports different-diameter.Present embodiment is provided with four faggings 7, wherein two fagging 7 parts by welded and installed in hold-fast ring 6 inner portion (referring to Fig. 3), in addition two faggings 7 by welded and installed at hold-fast ring 6 middle parts or the middle inboard (referring to Fig. 2) of position partially afterwards, put anti-sliding sleeve on each fagging 7, usually anti-sliding sleeve adopts rubber coating, is used for preventing that hanging object from sliding and reduce wearing and tearing to hanging object.
The big I of suspension hook 1 of the present invention, spring 2, fagging 7, hold-fast ring 6 is provided with according to actual needs, and fagging 7 can be a cuboid, and fagging 7 also can be joined with hold-fast ring 6 and is associated with certain radian, so that adapt to circular object better.Present embodiment utilizes spring 2, when not lifting by crane circular object, hold-fast ring 6 openings are magnified, so that can easily circular object be inserted in the spring suspension hook, when lifting, utilize the weight of circular object, the angle between two portable bars 4 is dwindled, thereby make two hold-fast rings 6 to the power of holding tightly at center, firmly fixing circular object.During practical application, suspension hook 1 hangs on driving or other weight-lifting equipments.The length and width of present embodiment fagging 7 are respectively 170 millimeters and 80 millimeters, and the thickness of fagging 7 is 10 millimeters, and the width of hold-fast ring 3 is 80 millimeters, and fagging 7 is fixedly connected by welding with hold-fast ring 6, and the two ends of fagging 7 respectively exceed 45 millimeters of hold-fast ring 6 width respectively.Because the two ends of fagging 7 exceed hold-fast ring 6, when saving hold-fast ring 6 materials, strengthened the contact surface of fagging 7 with hanging object, improved stability and reliability that fagging 7 is held hanging object tightly.Make whole suspension hook and ground contact surface increase simultaneously, it can be laid on the ground evenly.
Suspension hook of the present invention 1 hangs in weight-lifting equipment by rope etc. earlier, struts hold-fast ring 6 by the elastic force of spring 2.After the lifting, the hold-fast ring 6 stressed objects that need lifting of holding tightly can lift by crane safely and reliably.
The simple deformation or the combination of every embodiment of the invention technical scheme and technical characterictic all should be thought to fall into protection scope of the present invention.
