Description
Technical field
The utility model relates to a kind of hoisting sling, particularly a kind of two plate load hook.
Background technology
At present, load hook because structure is simple, volume is little, easy to use, be widely used in the various lifting fields such as storage, logistics, harbour handling.Wherein two plate load hook is mainly used in horizontal handling and the handling of laminate, slab or single steel plate.When lifting job by steel rope connecting shackle pulley, two suspension hooks use in pairs, time as larger in steel plate length, also can adopt multipair suspension hook co-operate.The hook body of of the prior art pair of plate suspension hook is that two tabular crotch shape suspension hook symmetries are installed together, when lifting the objects such as steel plate, two suspension hooks can not ensure uniform stressed, thus service life is short, and be improve intensity to carry out increase hook body Thickness Design, obvious cost is higher; In addition, because the diameter of pulley being installed in hook body top by bearing pin is little, steel rope is very easily wound around, clot, affect service life of steel wire rope, although also provide the description that some strengthen diameter of pulley in related documents, as diameter of pulley be steel rope 7 doubly with first-class, but in actual use, technique effect is unsatisfactory; In addition, because the external part of bearing pin lacks protection and the structure design reason of bearing pin own, in use, Chang Yin collides with and causes damage of product, or cannot dismantle because end part of pin shaft is out of shape; Further, be in pairs due to load hook or many groups are common uses, consumption is large, frequency of utilization is high, and how under the prerequisite ensureing product strength, improving product service life, expendable weight and effectively reducing costs also is a technical matters urgently to be resolved hurrily.
Utility model content
Technical problem to be solved in the utility model is just to provide a kind of two plate load hook, in order to overcome the technological deficiency existed in prior art.
The utility model solves the technical scheme that its technical matters adopts:
Two plate load hook, comprise the crotch shape hook body that two symmetries are installed together, and the steel rope lifting pulley on two hook body tops is folded in by bearing pin, it is an entirety that the inward facing surface of two hook body is fixedly connected by curved surface rigidity panel, the diameter of pulley is 4-5 times of wirerope diameter, bearing pin is fixed by nut and hook body, and hook body is provided with the circular arc backplate higher than nut axial height around nut.
Offer annular lightening grooves in the radial side of pulley, backplate is the semicircle backplate of symmetrical openings.
Panel is ramp structure in the upper end of the medial surface of hook body, and the bill portion of lower end and hook body is the curved surface seamlessly transitted.
Bottom hook body, be provided with roller, roller clip is located between two hook body.
On the medial surface of two hook body bottoms, symmetry is installed with brace panel.
Be smooth surface on the bearing pin surface of bearing pin and nut thread rigging position bottom, it is provided with spring cotter.
Technological advance acquired by the utility model is:
1, be one overall because the inward facing surface of two hook body is fixedly connected by curved surface rigidity panel, during use, increase the area of contact with hanging object compared to existing technology, suspension hook uniform force, extend product service life, and lifting steadily, safety is good; Diameter due to pulley is 4-5 times of wirerope diameter, through working condition experimenting inspection, effectively reduces wirerope-winding, clot phenomenon, extends service life of steel wire rope, ensure that safety in production; Owing to being provided with the circular arc backplate higher than nut axial height around nut in hook body, effectively can preventing the damage of colliding with to product in transporting and using, further increase the service life of product.
2, owing to offering annular lightening grooves in the radial side of pulley, decrease pulley weight, be convenient to manual operation; Due to the semicircle backplate that backplate is symmetrical openings, while the external end of protection bearing pin, the installing/dismounting of bearing pin also can be facilitated.
3, because panel is ramp structure in the upper end of the medial surface of hook body, the stress avoided when hoisting object is concentrated; The bill portion of lower end and hook body is the curved surface seamlessly transitted, and avoids by the damage of lifting object as surface of steel plate.
4, bottom hook body, be provided with roller, roller clip is located between two hook body, conveniently can move back hook when putting down suspended object, without the need to again by the operation such as chock and cushion block, improves work efficiency.
5, due on the medial surface of two hook body bottoms, symmetry is installed with brace panel, while increase hook body intensity, can reduce hook body weight, reduce productive costs.
6, because the bearing pin surface at bearing pin and nut thread rigging position bottom is smooth surface, in actual use, often there will be bearing pin close end screw thread due to reasons such as external force collisions causes thread failure, and then there is dismounting hinge pin difficulty situation, and said structure design, effectively can avoid this phenomenon; It is provided with spring cotter, fixation, dismounting is simple and easy.
