The utility model content
Technical problem to be solved in the utility model provides a kind of can guarantee to lift stable and firmly, can not produce damage parts, easy to operate, the stable firmly suspension hook pawl of lifting saving manpower, raise the efficiency in being lifted with the irregular part of larger stepped hole.
The technical scheme that solves the problems of the technologies described above is:
The stable firmly suspension hook pawl of a kind of lifting, it is by hook, connecting arm, terminal pad, iron chains, hoisting ring, the handle ring, rotating shaft forms, hook, connecting arm, iron chains is respectively three, one end of three connecting arms is fixed end, they are along the circumference uniform distribution of terminal pad, be welded to connect with terminal pad, connecting bore is arranged on the connecting arm, there is hole for hoist the upper end of hook, and there is connecting shaft hole at the middle part, and there is crotch the lower end, the connecting shaft hole at hook middle part is connected with the connecting bore of connecting arm by rotating shaft, one end of three iron chains is connected in the hole for hoist of three hook upper ends, and the other end is connected in the hoisting ring, and the handle boxing is connected on the top of terminal pad.
The stable firmly suspension hook pawl of above-mentioned lifting, the connecting bore on the described connecting arm is a plurality of, along the axial distribution of connecting arm.
The stable firmly suspension hook pawl of above-mentioned lifting, it also has reaction plate, and reaction plate lays respectively at the up and down both sides of connecting arm with terminal pad below terminal pad, and the fixed end of reaction plate and connecting arm is welded to connect.
Usefulness of the present utility model is:
The lower end crotch of three hooks of the present utility model can stretch in the endoporus of lifting object, the pull-up hoisting ring, and hook can rotate around connecting arm, and lifting object is sling on the lower edge that makes the crotch of hook lower end catch on the lifting object endoporus.The suspension hook pawl of this structure can guarantee the stable and firm of lifting operation, can not make by the lifting part to produce cut, collide with, drop, and also can not affect product design.The utility model is simple in structure, easy to operate, efficient is high, long service life, cost are low, is the very strong lifting device of a kind of practicality, is specially adapted to be lifted with the irregular heavy parts of larger stepped hole.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of hook.
Mark is as follows among the figure: hook 1, connecting arm 2, iron chains 3, hole for hoist 4, connecting shaft hole 5, rotating shaft 6, connecting bore 7, reaction plate 8, terminal pad 9, hoisting ring 10, handle ring 11.
The specific embodiment
The utility model is a kind of suspension hook pawl, replaces existing lifting mode with the suspension hook pawl, and the suspension hook pawl adopts lever principle to be lifted with the irregular part of larger stepped hole.
The utility model is comprised of parts such as hook 1, connecting arm 2, terminal pad 9, iron chains 3, hoisting ring 10, handle ring 11, rotating shafts 6.
Show among the figure that hook 1, connecting arm 2, iron chains 3 are respectively three.
Show among the figure that there is hole for hoist 4 upper end of hook 1, there is connecting shaft hole 5 at the middle part, and there is crotch the lower end, and the connecting shaft hole 5 at hook 1 middle part is connected with connecting arm 2 by rotating shaft 6, makes hook 1 with respect to freely activity of rotating shaft 6.
Show among the figure that an end of three connecting arms 2 is fixed end, they are welded to connect with terminal pad 9 along the circumference uniform distribution of terminal pad 9, and a plurality of connecting bores 7 are arranged on the connecting arm 2, and connecting arm 2 is connected with hook 1 by connecting bore 7.Handle ring 11 is welded on the top of terminal pad.
It also has reaction plate 8, and reaction plate 8 lays respectively at the up and down both sides of connecting arm 2 with terminal pad 9 below terminal pad 9, and reaction plate 8 is welded to connect with the fixed end of connecting arm 2, and the effect of reaction plate 8 is Joint strenghts of strengthening connecting arm 2 and terminal pad 9.
Be drilled with three connecting bores 7 on the connecting arm 2 of an embodiment of the present utility model, when assembling suspension hook pawl, according to the connecting bore 7 on the endoporus size Selection use connecting arm 2 of the part that will lift, undersized endoporus is selected the connecting bore 7 near handle ring 11 positions, otherwise uses the connecting bore 7 away from handle ring 11.Each connecting bore 7 has certain lifting scope.
Show among the figure that an end of three iron chains 3 is connected in the hole for hoist 4 of three hook 1 upper ends, the other end is connected in the hoisting ring 10.During lifting, upwards draw hoisting ring 10, the lower end of iron chains 3 is pulled upwardly hook 1 upper end.
When hook 1 was installed in connecting arm 2 outermost connecting bore 7, the length of iron chains 3 is the shortest should to guarantee that three hooks 1 collide under the effect of external force, so just can make hook 1 reach hole dimension in the minimum lifting.But iron chains 3 can not be oversize.
