Abstract

The utility model discloses a rotary lift hook, including coupler body, rotary device, electric telescopic handle, lifting hook root and connecting rod, the coupler body includes head, first flexion and second flexion, rotary device includes motor, axle center, first gear and second gear, the appear lug swing joint on groove and the top of connecting rod of the worker of second flexion through the end, the other end fixedly connected with electric telescopic handle of connecting rod, electric telescopic handle's terminal fixedly connected with lifting hook root. Finely tuning the position of lifting hook through the operation to electric telescopic handle and rotary device, making the more accurate heavy object that snatchs of lifting hook, heliciform perthitic texture is taked to the lifting hook root in addition, is difficult to in the use drop, and the structure into the flat horizontal surface is established to the inner wall of the first flexion of coupler body, the dispersion atress, and be equipped with the enhancement liner, the lifting hook wearing and tearing can be reduced and life is increased.

Description

A kind of shackle hook

Technical field

The utility model relates to mechanical field, is specially a kind of shackle hook.

Background technology

Suspension hook is modal a kind of suspender in elevator machinery, often by means of member hangs such as assembly pulleys on the steel rope of lifting mechanism.The load-engaging device that suspension hook is most widely used on being, manufactures simple, easy to use, and it carries whole load of handling.

Shackle hook uses a kind of connection with other rigging fittingses, and the suspension hook of lifting angle and rotation can be changed arbitrarily, but need in the process due to rotation, by inertia, to manipulate inconvenience, and in use, the movement of suspension hook is all by the effect of hoisting crane swing arm.

Utility model content

The purpose of this utility model is to provide a kind of shackle hook, to solve the problem proposed in above-mentioned background technology.

For achieving the above object, the utility model provides following technical scheme: a kind of shackle hook, comprise coupler body, slewing arrangement, electric expansion bar, suspension hook root and pipe link, described coupler body comprises head, first curve and the second curve, described head is closely fitted with the first curve, described first curve is closely fitted with the second curve, described slewing arrangement comprises motor, axle center, first gear and the second gear, described motor is fixedly mounted on the outside face of pipe link, described motor is connected with the first gear by axle center, described second gear is arranged on the outer surface edge of the second curve, described first gear and the second gears meshing, described second curve is flexibly connected with the projection on the top of pipe link by the work shape groove of end, the other end of described pipe link is fixedly connected with electric expansion bar, the end of described electric expansion bar is fixedly connected with suspension hook root.

Preferably, the inwall of described first curve is flat horizontal surface structure, and is provided with reinforcement liner.

Preferably, described head, the first curve and the second curve are formed in one structure.

Compared with prior art, the beneficial effects of the utility model are: this shackle hook, be provided with the structures such as electric expansion bar, slewing arrangement, realize finely tuning suspension hook, capture weight more accurately, and suspension hook root takes barber-pole structure, more difficultly in use procedure to come off, the inwall of the first curve of coupler body is set to the structure of flat horizontal surface and is provided with reinforcement liner, can increase and reduce suspension hook wearing and tearing service life.

Accompanying drawing explanation

Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model pipe link and the second curve connection diagram.

In figure: 1 coupler body, 2 slewing arrangements, 3 electric expansion bars, 4 suspension hook roots, 5 pipe links, 11 heads, 12 first curves, 13 second curves, 21 motors, 22 axle center, 23 first gears and 24 second gears.

Detailed description of the invention

Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.

Refer to Fig. 1-2, the utility model provides a kind of technical scheme: the utility model provides a kind of shackle hook as shown in Figure 1, comprise coupler body 1, slewing arrangement 2, electric expansion bar 3, suspension hook root 4 and pipe link 5, described coupler body 1 comprises head 11, first curve 12 and the second curve 13, described head 11, first curve 12 and the second curve 13 are formed in one structure, described head 11 is closely fitted with the first curve 12, the inwall of described first curve 12 is flat horizontal surface structure, disperse stressed, and be provided with reinforcement liner, in use reduce suspension hook wearing and tearing and increase service life, described first curve 12 is closely fitted with the second curve 13, described slewing arrangement 2 comprises motor 21, axle center 22, first gear 23 and the second gear 24, described motor 21 is fixedly mounted on the outside face of pipe link 5, described motor 21 is connected with the first gear 23 by axle center 22, described second gear 24 is arranged on the outer surface edge of the second curve 13, described first gear 23 engages with the second gear 24, rotated by the motor 21 rotating band moving axis heart 22, axle center 22 drives the first gear 23 to rotate, first gear 23 drives the second gear 24 to rotate, realize the rotation of coupler body 1, described second curve 13 is flexibly connected with the projection on the top of pipe link 5 by the work shape groove of end, the other end of described pipe link 5 is fixedly connected with electric expansion bar 3, the end of described electric expansion bar 3 is fixedly connected with suspension hook root 4, the inner chamber of described suspension hook root 4 is cored screw structure, after being connected with hoisting crane and using, be not easy to come off, the structure such as slewing arrangement 2 and electric expansion bar 3 is added in suspension hook design, by sequence of operations, suspension hook is finely tuned to the object reaching and capture weight more accurately.

Although illustrate and described embodiment of the present utility model, for the ordinary skill in the art, be appreciated that and can carry out multiple change, amendment, replacement and modification to these embodiments when not departing from principle of the present utility model and spirit, scope of the present utility model is by claims and equivalents thereof.
