Abstract

The utility model discloses a hook device which comprises a pulley, a pulley shaft and a hook; the tail end of the hook is provided with a pulley cavity; shaft holes are formed in two side walls in the pulley cavity; the pulley is installed in the pulley cavity through the shaft holes by the pulley shaft; the inner side surface at the front end of the hook is provided with at least one protrusion; in the hook device, the pulley cavity and the pulley are directly arranged at the tail end of the hook, unnecessary devices, such as a lifting ring, a connecting shaft, peripheral materials of the pulley and the like arranged in other devices, are omitted, so that multiple production and manufacturing materials and time are saved, and the efficiency is improved; meanwhile, the unnecessary materials can be added to a hook main body, so that the weight of the hook is increased, and the hook can be firm and stable; the protrusion arranged on the inner side surface at the front end of the hook plays a blocking role, so that materials such as a rope lifted on the hook are prevented from falling off; and compared with the similar type of devices, the hook device provided by the utility model has the advantages that the structure is simpler and more convenient, lifting materials can be prevented from falling off directly without operation, and the like.

Description

Cargo hook gear

Technical field:

The utility model belongs to machinery manufacturing technology field, is specifically related to the cargo hook gear that operation is used in a kind of mechanical engineering.

Background technology:

At present, the suspension hook that in hoisting operation, has been widely used, it leans on the hook load capacity, but existing these cargo hook gear complex structures, production process is loaded down with trivial details, and the efficient of application is relatively low, and reflection is clumsy especially; And do not limit or encumbrance on the suspension hook, hang superincumbent material with dangerous property, non insurance; And mostly be dead bolt in many instantly restrictions or encumbrance; And also have the switching mechanism of control lock tongue, these mechanisms are complex structure not only, and also comparatively loaded down with trivial details in operation.

Summary of the invention:

The purpose of the utility model is to overcome the problem that exists in the prior art and a kind of cargo hook gear is provided, and is used for safe and reliable, the brisk material of transferring efficiently.

The technical scheme of the utility model is achieved in that a kind of cargo hook gear; Comprise pulley, sheave shaft, suspension hook; End at suspension hook is provided with the pulley chamber, in this pulley chamber, has axis hole on the two side, and described sheave shaft is installed in pulley in the pulley chamber through this axis hole.

On the medial surface of said suspension hook front end, be provided with convexity.

Described convexity at least one.

The good effect of the utility model: the end that in this cargo hook gear, directly pulley chamber and pulley is arranged on suspension hook; Eliminated unnecessary external equipment; Like the peripheral material of the suspension ring, adapter shaft and the pulley that have in other devices etc.; Save many manufacturing material and time, improved efficient; Simultaneously those unnecessary materials are increased on the main hook part, increase the weight of suspension hook, can make suspension hook more firm steady; The convexity that on suspension hook front end medial surface, is provided with takes blocking effect, and prevents to hang coming off of materials such as rope on suspension hook, and this aspect ratio same device structure is easier, need not operation, can directly stop advantages such as coming off of hanging object.

Description of drawings:

Fig. 1 is the structural front view of the utility model.

Fig. 2 is the structure right elevation of the utility model.

The specific embodiment:

Embodiment: like Fig. 1, shown in 2; This cargo hook gear comprises pulley 4, sheave shaft 5, suspension hook 1; End at suspension hook 1 is provided with pulley chamber 2, in this pulley chamber 2, has axis hole 3 on the two side, and described sheave shaft 5 is installed in pulley 4 in the pulley chamber 2 through this axis hole 3.

On the medial surface of said suspension hook 1 front end, be provided with protruding 6.

Described protruding 6 is one.

During application, steel rope is contained on the pulley, just can have carried out fast and reliable material allocation flexibly.
