Abstract
The utility model relates to a lifting hook, concretely relates to screwed pipe safety lifting hook, including two wire rope lugs of connecting axle and symmetric distribution, the wire rope lug is equipped with main lifting hook on being fixed in the connecting axle in the middle of two wire rope lugs, and main lifting hook is articulated with the connecting axle, and main lifting hook both sides are equipped with supplementary lifting hook, and supplementary lifting hook is articulated with the connecting axle, main lifting hook includes coupler body and articulated joint, and the coupler body end is equipped with the arc non slipping spur, is equipped with V type antiskid tooth on the arc non slipping spur, supplementary lifting hook includes articulated joint and acute angle couple. At the hoist and mount in -process of pipeline, when the coupler body breaking occur of main lifting hook, the supplementary lifting hook of two symmetric distributions can play the effect of main lifting hook, be equipped with the arc non slipping spur on the main lifting hook for quilt hoist and mount screwed pipe is the face contact with main lifting hook, compares than the lifting hook of point contact to have higher security and reliability. The utility model has the advantages of simple structure, reasonable in design, easy operation, safe and reliable, low cost, economy is suitable for.
Description
technical field:
The utility model relates to a kind of suspension hook, is specifically related to the safe load hook of a kind of threaded line pipe.
background technology:
To produce and in transportation at metallic conduit, the movement of pipeline, pile up, the operation such as handling all be unable to do without hoisting crane, and the equipment of a crane hook direct and tube contacts especially.In the past when crane pipeline, general is all suspension hook is directly hung on pipe ends to lift by crane, because suspension hook becomes point cantact with pipe end, contact surface is little and pipeline is heavier, particularly large-scale pipeline can reach several tons or tens of tons, in hoisting process, if there is sharp impacts to there will be unhook phenomenon, cause device damage and personal casualty, existing load hook lacks certain safety and reliability.So designing a kind of threaded line pipe, to lift special safe load hook be very necessary.
utility model content:
The utility model makes up and improves above-mentioned the deficiencies in the prior art part, provide the safe load hook of simple, reasonable in design, simple to operate, safe and reliable, with low cost, the economic and practical threaded line pipe of a kind of structure, can promote on a large scale in the production of Guan Ye and use.
The technical solution adopted in the utility model is: the safe load hook of a kind of threaded line pipe, comprise adapter shaft and symmetrical two wire rope ears, wire rope ear is fixed on adapter shaft, main suspension hook is provided with in the middle of two wire rope ears, main suspension hook and adapter shaft hinged, main suspension hook both sides are provided with auxiliary suspension hook, auxiliary suspension hook and adapter shaft hinged; Main suspension hook comprises coupler body and articulated joint, and coupler body end is provided with arc nonslipping spur, and arc nonslipping spur is provided with V-type anti-skid teeth; Auxiliary suspension hook comprises articulated joint and acute angle hook.
The acute angle of described acute angle hook is 50 degree to 60 degree.
Described wire rope ear is provided with connecting bore.
The radian of described arc nonslipping spur is consistent with the radian of lifting threaded line pipe.
The beneficial effects of the utility model: structure is simple, reasonable in design, simple to operate, safe and reliable, with low cost, economic and practical, can promote on a large scale and use in pipe industry is produced.Its major advantage is as follows:
1), described main suspension hook is provided with arc nonslipping spur, and making to be lifted threaded line pipe with main suspension hook is that face contacts, and compares have higher safety and reliability compared with the suspension hook of point cantact, and structure is simple, reasonable in design, safe and reliable, economic and practical.
2), described V-type anti-skid teeth has anti-skidding effect, avoids threaded line pipe and causes because there is sharp impacts breaking off relations in hoisting process, decrease the probability of personal casualty and device damage, reasonable in design, safe and reliable, with low cost.
3), in the hoisting process of pipeline, when fracture occurs the coupler body of main suspension hook, two symmetrical auxiliary suspension hooks can play the effect of main suspension hook, avoid pipeline fall and cause casualties and device damage, reasonable in design, safe and reliable, economic and practical.
4), described main suspension hook and auxiliary suspension hook and adapter shaft hinged, avoid and cause steel rope unbalance stress to rupture because pipeline amplitude of fluctuation is excessive in hoisting process, structure is simple, reasonable in design, safe and reliable, economic and practical.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of main suspension hook in the utility model.
Fig. 3 is the left view of Fig. 2.
Fig. 4 is the structural representation of auxiliary suspension hook in the utility model.
detailed description of the invention:
With reference to each figure, the safe load hook of a kind of threaded line pipe, comprise adapter shaft 1 and symmetrical two wire rope ears 2, wire rope ear 2 is fixed on adapter shaft 1, main suspension hook 4 is provided with in the middle of two wire rope ears 2, main suspension hook 4 is hinged with adapter shaft 1, and main suspension hook 4 both sides are provided with auxiliary suspension hook 3, and auxiliary suspension hook 3 is hinged with adapter shaft 1; Main suspension hook 4 comprises coupler body 6 and articulated joint 5, and coupler body 6 end is provided with arc nonslipping spur 7, and arc nonslipping spur 7 is provided with V-type anti-skid teeth 8; Auxiliary suspension hook 3 comprises articulated joint 5 and acute angle hook 9, and the acute angle of acute angle hook 9 is 50 degree to 60 degree; Described wire rope ear 2 is provided with connecting bore; The radian of described arc nonslipping spur 7 is consistent with the radian of lifting threaded line pipe.Described main suspension hook 4 is provided with anti-skidding 7 pieces of arc, makes to be lifted threaded line pipe with main suspension hook 4 for face contacts, and compares have higher safety and reliability compared with the suspension hook of point cantact; Described V-type anti-skid teeth 8 has anti-skidding effect, avoids threaded line pipe and causes because there is sharp impacts breaking off relations in hoisting process, decrease the probability of personal casualty and device damage; In the hoisting process of pipeline, when fracture occurs the coupler body 6 of main suspension hook 4, two symmetrical auxiliary suspension hooks 3 can play the effect of main suspension hook 4, avoid pipeline fall and cause casualties and device damage; Described main suspension hook 4 and auxiliary suspension hook 3 hinged with adapter shaft 1, avoid and cause steel rope unbalance stress to rupture because pipeline amplitude of fluctuation is excessive in hoisting process.Structure of the present utility model is simple, reasonable in design, simple to operate, safe and reliable, with low cost, economic and practical, can promote on a large scale in pipe industry is produced and use.
