Abstract
The invention discloses a novel wear-resisting lifting hook. The novel wear-resisting lifting hook comprises a hook body and a connection part arranged on the upper part of the hook body, wherein the hook body comprises a hook body part, a hook bottom part and a hook tip part; a wear-resisting compound coating is arranged on the outer surface of the hook bottom part; the wear-resisting compound coating comprises a chromium carbide wear-resisting coating, a silicon nitride wear-resisting coating and a tungsten carbide wear-resisting coating which are sequentially arranged from inside to outside. By virtue of the manner, the novel wear-resisting lifting hook has a good wear-resisting performance and is long in service life.
Description
Technical field
The present invention relates to weight-lifting equipment technical field, particularly relate to a kind of wear-resistant load hook.
Background technology
Suspension hook is one of most important parts in all kinds of elevator machineries.Suspension hook is divided into single hook and double hook by shape, by manufacture method, is divided into and forges suspension hook and stacked suspension hook.
Suspension hook in use, can be subject to more serious wearing and tearing at the bottom of the hook of suspension hook, and the abrasion resistance properties of existing suspension hook is not good, and service life is short.
Summary of the invention
The technical matters that the present invention mainly solves is to provide a kind of wear-resistant load hook, has preferably resistance to abrasion performance, 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-resistant load hook is provided, comprise: suspension hook body and the connecting portion that is arranged on described suspension hook body top, described suspension hook body comprises hook body portion, hook bottom and bill portion, on the outside face of described hook bottom, be provided with wear-resistant composite coating, described wear-resistant composite coating comprises that the chromium carbide abrasion-resistant coatings, the silicon nitride wear resistant that from inside to outside set gradually damage coating and carbine abrasion-proof damages coating.
In a preferred embodiment of the present invention, the thickness of described chromium carbide abrasion-resistant coatings is 15 ~ 20 μ m.
In a preferred embodiment of the present invention, the thickness that described silicon nitride wear resistant damages coating is 8 ~ 13 μ m.
In a preferred embodiment of the present invention, the thickness that described carbine abrasion-proof damages coating is 20 ~ 40 μ m.
In a preferred embodiment of the present invention, in described hook body portion, be provided with anti-drop device.
The invention has the beneficial effects as follows: the wear-resistant load hook that the present invention discloses, has preferably resistance to abrasion performance, long service life.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also according to these accompanying drawings, obtain other accompanying drawing, wherein:
Fig. 1 is the structural representation of wear-resistant load hook one preferred embodiment of the present invention;
Fig. 2 is the layer structural representation of described wear-resistant composite coating.
In accompanying drawing, the mark of each parts is as follows: 1, suspension hook body, 2, connecting portion, 3, hook body portion, 4, hook bottom, 5, bill portion, 6, chromium carbide abrasion-resistant coatings, 7, silicon nitride wear resistant damages coating, 8, carbine abrasion-proof damages coating.
The specific embodiment
Below the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making all other embodiment that obtain under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1 and Fig. 2, the embodiment of the present invention comprises:
A kind of wear-resistant load hook, comprise: suspension hook body 1 and the connecting portion 2 that is arranged on described suspension hook body 1 top, described suspension hook body 1 comprises hook body portion 3, hook bottom 4 and bill portion 5, on the outside face of described hook bottom 4, be provided with wear-resistant composite coating, described wear-resistant composite coating comprises that the chromium carbide abrasion-resistant coatings 6, the silicon nitride wear resistant that from inside to outside set gradually damage coating 7 and carbine abrasion-proof damages coating 8.
By described chromium carbide abrasion-resistant coatings 6, silicon nitride wear resistant, damage the combination of coating 7 and carbine abrasion-proof damage coating 8, effectively strengthened the abrasion resistance properties of hook bottom 4, extended service life.
The thickness of described chromium carbide abrasion-resistant coatings 6 is 15 ~ 20 μ m.
The thickness that described silicon nitride wear resistant damages coating 7 is 8 ~ 13 μ m.
The thickness that described carbine abrasion-proof damages coating 8 is 20 ~ 40 μ m.
In described hook body portion 3, be provided with anti-drop device.
The wear-resistant load hook that the present invention discloses, has preferably resistance to abrasion performance, long service life.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
