Abstract
The invention discloses a wear-resisting durable lifting hook. The wear-resisting durable lifting hook comprises a lifting hook body, wherein the lifting hook body comprises a hook body part, a hook bottom part and a hook tip part; the section of the hook bottom part is of a T shape, the hook bottom part comprises a hook bottom body and two side bulge parts, and the upper surface of the hook bottom part and the outer surfaces of the two side bulge parts are provided with strengthening wear-resisting layers; the strengthening wear-resisting layers comprise nitrogen titanium carbide bottom layers, aluminium nitride middle layers arranged on the outer surfaces of the nitrogen titanium carbide bottom layers and aluminium oxide outer layers arranged on the outer surfaces of the aluminium oxide. Through the manner, the wear-resisting durable lifting hook provided by the invention has the advantages that the structure is simple and reasonable, the wear-resisting property is good, the damage of the hook from a lifting rope is relieved, and the service life is long.
Description
Technical field
The present invention relates to suspension hook technical field, particularly relate to a kind of wear-resisting durable load hook.
Background technology
Suspension hook is modal a kind of suspender in elevator machinery.Suspension hook is often suspended on the steel rope of lifting mechanism by means of parts such as assembly pulleys.
Suspension hook in use, can be subject to the severe wear of the lifting ropes such as steel rope at the bottom of the hook of suspension hook, the wear resisting property of existing suspension hook is not good, and service life is short, has affected the in-use performance of suspension hook.
Summary of the invention
The technical matters that the present invention mainly solves is to provide a kind of wear-resisting durable load hook, and simple and reasonable, abrasion resistance properties is good, has alleviated the damage of lifting rope to suspension hook, long service life.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of wear-resisting durable load hook is provided, comprise: suspension hook body, described suspension hook body comprises hook body portion, hook bottom and bill portion, the cross section of described hook bottom is in T shape, described hook bottom comprises hook copy for the record or for reproduction body and two side protuberances, on the upper surface of described hook copy for the record or for reproduction body and the outside face of two side protuberances, be provided with reinforcement wearing layer, described reinforcement wearing layer comprises TiCN bottom, the alundum (Al2O3) that is arranged on the aluminium nitride interlayer on described TiCN bottom outside face and is arranged on described aluminium nitride interlayer outside face is outer.
In a preferred embodiment of the present invention, the thickness of described aluminium nitride interlayer is greater than the thickness of TiCN bottom, and the outer field thickness of described alundum (Al2O3) is greater than the thickness of aluminium nitride interlayer.
In a preferred embodiment of the present invention, in described hook body portion, be provided with anti-slip parts.
In a preferred embodiment of the present invention, the top of described hook body portion is provided with coupling end.
In a preferred embodiment of the present invention, described suspension hook body adopts Fine Steel Casting iron to make.
The invention has the beneficial effects as follows: the wear-resisting durable load hook of the present invention, simple and reasonable, abrasion resistance properties is good, has alleviated the damage of lifting rope to suspension hook, long service life.
Accompanying drawing explanation
