Abstract
The invention discloses a steel wire rope winding drum structure for lifting equipment. The steel wire rope winding drum structure comprises an inner supporting drum body and an outer replacement drum body connected to the outer portion of the inner supporting drum body in a sleeved mode. The inner supporting drum body is connected with the outer replacement drum body through threads, the two ends of the inner supporting drum body are respectively provided with a flange, a central shaft is arranged inside the inner supporting drum body, a composite anti-abrasion layer is arranged on the outer portion of the outer replacement drum body, and the composite anti-abrasion layer comprises a silicon nitride layer arranged on the outer surface of the outer replacement drum body and a chromium nitride layer arranged on the outer surface of the silicon nitride layer. Through the method, the steel wire rope winding drum structure for the lifting equipment is novel, when the winding drum is seriously abraded, the whole winding drum does not need to be replaced, and therefore the use cost is lowered.
Description
Technical field
The present invention relates to the weight-lifting equipment technical field, particularly relate to a kind of weight-lifting equipment wire rope roll barrel structure.
Background technology
Weight-lifting equipment refers to for referring to the electromechanical appliance of carrying or moving heavy object.Weight-lifting equipment can be divided into several classes such as small-sized weight-lifting equipment, elevator, hoisting crane and overhead monorail system by the structure difference.Cable drum is to be used for the parts of lay winding wire ropes in weight-lifting equipment, and cable drum in use can be subject to the wearing and tearing of steel rope, thereby causes scrapping of whole reel, needs integral replacing, has increased cost.
Summary of the invention
The technical matters that the present invention mainly solves is to provide a kind of weight-lifting equipment wire rope roll barrel structure, and novel structure, during the reel serious wear, need not be changed whole reel, has reduced use cost.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of weight-lifting equipment wire rope roll barrel structure is provided, comprise: inner support cylindrical shell and the outer replacing cylindrical shell that is socketed in described inner support cylindrical shell outside, between described inner support cylindrical shell and outer replacing cylindrical shell, be threaded connection, the two ends of described inner support cylindrical shell respectively are provided with a flange, described inner support inner barrel is provided with center shaft, the outer setting of described outer replacing cylindrical shell has composite wear-resistant layer, described composite wear-resistant layer comprises the silicon nitride layer be arranged on outer replacing barrel outer surface and is arranged on the chromium nitride layer on described silicon nitride layer outside face.
In a preferred embodiment of the present invention, the wall thickness of described inner support cylindrical shell is 3 ~ 7 centimetres.
In a preferred embodiment of the present invention, the wall thickness of described outer replacing cylindrical shell is 1.2 ~ 2 centimetres.
In a preferred embodiment of the present invention, on the inwall of described inner support cylindrical shell, be provided with zinc coating.
The invention has the beneficial effects as follows: weight-lifting equipment of the present invention wire rope roll barrel structure, novel structure, during the reel serious wear, need not change whole reel, reduced use cost.
The accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, in below describing embodiment, the accompanying drawing of required use is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings, wherein:

Below will the technical scheme in the embodiment of the present invention be 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 the 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 weight-lifting equipment wire rope roll barrel structure, comprise: inner support cylindrical shell 1 and the outer replacing cylindrical shell 2 that is socketed in described inner support cylindrical shell 1 outside, between described inner support cylindrical shell 1 and outer replacing cylindrical shell 2, be threaded connection, the two ends of described inner support cylindrical shell 1 respectively are provided with a flange 3, described inner support cylindrical shell 1 inside is provided with center shaft 4, when outer replacing cylindrical shell 2 serious wear, the outer replacing cylindrical shell 2 that can more renew, can not cause scrapping of whole reel.
The outer setting of described outer replacing cylindrical shell 2 has composite wear-resistant layer, described composite wear-resistant layer comprises the silicon nitride layer 5 be arranged on outer replacing cylindrical shell 2 outside faces and is arranged on the chromium nitride layer 6 on described silicon nitride layer 5 outside faces, strengthened the abrasion resistance properties of outer replacing cylindrical shell 2.
The wall thickness of described inner support cylindrical shell 1 is 3 ~ 7 centimetres.
The wall thickness of described outer replacing cylindrical shell 2 is 1.2 ~ 2 centimetres.
Be provided with zinc coating on the inwall of described inner support cylindrical shell 1, promoted the decay resistance of inner support cylindrical shell 1.
Weight-lifting equipment of the present invention wire rope roll barrel structure, novel structure, during the reel serious wear, need not change whole reel, reduced use cost.
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 directly or indirectly be used in other relevant technical field, all in like manner be included in scope of patent protection of the present invention.
