Technical field:
The present invention relates to a kind of suspension hook that is used to lift by crane circular object, it belongs to parts in the weight-lifting equipment.
Background technology:
The suspension hook of weight-lifting equipment is various in style at present, emerges in an endless stream.But aspect the suspension hook of the circular heavy metal object of lifting, still have defective, or suspension hook targetedly specially not; Or complex structure, cost is higher.
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 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 suspension hook of circular object, comprise suspension ring, it is characterized in that also being provided with fagging, screw rod, hold-fast ring, the movable arm of force, a hold-fast ring is captiveed joint with a movable arm of force and is constituted a coupler body, two coupler bodies relatively rotate connection by the screw rod on two movable arm of forces, two coupler bodies are symmetrically distributed, described suspension ring are captiveed joint with two movable arm of force tops respectively, fagging is installed on the hold-fast ring, and described screw rod is installed in the middle and lower part of the movable arm of force.Make the present invention can be specially adapted for the lifting of circular object thus, be particularly useful for the lifting of circular heavy metal object.
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.
Fagging of the present invention can cooperate with the hold-fast ring radian.
Described fagging of the present invention and hold-fast ring are fixedly connected by welding.The shape of fagging can be a cuboid.
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 suspension hook that the embodiment of the invention is used to lift by crane circular object is provided with suspension ring A, fagging B, screw rod C, hold-fast ring D, movable arm of force E, a hold-fast ring D and a movable arm of force E fuse, constitute a coupler body, two coupler bodies relatively rotate connection by the screw rod C (being fulcrum) on two movable arm of force E, two suspension ring A are captiveed joint with two movable arm of force E tops, fagging B symmetric transverse is installed on the hold-fast ring D, the two ends of fagging B exceed the same distance of hold-fast ring D, be used for holding tightly the hanging object that supports different-diameter, when saving hold-fast ring D material, strengthen the contact surface of fagging B and hanging object, improved stability and reliability that fagging B holds hanging object tightly.Make whole suspension hook and ground contact surface increase simultaneously, it can be laid on the ground evenly.
Present embodiment is provided with four fagging B, wherein two fagging B parts by welded and installed in hold-fast ring D inner portion (referring to Fig. 3), in addition two fagging B by welded and installed at hold-fast ring D middle part or the middle inboard (referring to Fig. 2) of position partially afterwards, put anti-sliding sleeve on each fagging B, 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 ring A of the present invention, fagging B, screw rod C, hold-fast ring D, movable arm of force E is provided with according to actual needs, and fagging B can be a cuboid, certain radian also can be arranged and cooperates with hold-fast ring D, so that adapt to circular object better.As a kind of special case, present embodiment screw rod C is arranged on last 6: 1～5: 1 position of movable arm of force E, promptly when the movable arm of force E of present embodiment is 600 millimeters, screw rod C is arranged on the position of 100～150 millimeters of distance movable arm of force E and hold-fast ring D coupling ends, thereby utilize lever principle, effectively save power.The diameter of suspension ring A is 100 millimeters, and during practical application, suspension ring A hangs on driving or other weight-lifting equipments.The thickness of hold-fast ring D is 10 millimeters, and the diameter of hold-fast ring D is in 850 millimeter, and two hold-fast ring D open when constituting the annulus local shape, and the distance of two hold-fast ring D heads is 400 millimeters.The length and width of fagging B are respectively 170 millimeters and 80 millimeters, and the thickness of fagging B is 10 millimeters, and the width of hold-fast ring D is 80 millimeters, and fagging B and hold-fast ring D are fixedly connected by welding, and the two ends of fagging B respectively exceed 45 millimeters of hold-fast ring D width respectively.
Suspension ring of the present invention hang in weight-lifting equipment by rope etc. earlier, ensure certain space that struts.According to lever principle, be used for movable arm of force E with less masterpiece, produce the power of opening to regulate hold-fast ring D, hold the object that needs lifting tightly after, the operation weight-lifting equipment gets final product.
