Abstract
The utility model provides a wear-resisting drilling device which comprises a drill bit, a drill rod and a connecting piece. The connecting piece comprises a front end, a rear end and a side wall. The front end of the connecting piece is connected with the drill bit. The rear end of the connecting piece is connected with the drill rod. The side wall of the connecting piece is arranged between the front end and the rear end. A wear-resisting layer is formed on the side wall. Compared with the prior art, as the wear-resisting layer is formed on the side wall of the connecting piece in an electroplating mode, wear-resisting performance of the connecting piece can be enhanced greatly. Moreover, in the working process, replacement does not need to be carried out frequently, so work efficiency is improved and whole work cost is also lowered.
Description
Technical field
The utility model relates to a kind of drilling equipment, relates in particular to the wear-resisting drilling equipment that a kind of connector has better wearability.
Background technology
At present, drilling equipment is widely used in numerous occasions, and it mainly relies on the high speed rotation of drill bit, thereby forms boring at object.Drilling equipment generally comprises the connector that drill bit is connected with drill bit, wherein, the higher object of hardness is being holed, because the material of described connector is generally iron or steel, therefore described connector very easily is worn, thereby need often maintenance even replacing, caused operating efficiency reduction and cost to increase.
The utility model content
The technical problem that the utility model mainly solves is that the connector of drilling equipment is not wear-resisting, very easily is worn.
In order to solve the problems of the technologies described above, the utility model embodiment discloses a kind of wear-resisting drilling equipment, described wear-resisting drilling equipment comprises drill bit, drilling rod and connector, described connector comprises front end, rear end and sidewall, the front end of described connector is connected with described drill bit, the rear end of described connector is connected with described drilling rod, and the sidewall of described connector and is formed with wearing layer on the described sidewall between described front end and described rear end.
In a preferred embodiment of the present utility model, described wearing layer is titanium layer or titanium alloy layer.
In a preferred embodiment of the present utility model, described wearing layer is formed on the sidewall of described connector by the electric welding mode.
In a preferred embodiment of the present utility model, described connector is cylindrical structure.
In a preferred embodiment of the present utility model, bar and back bar before described drilling rod comprises, the two ends of described preceding bar are connected with described back bar with described connector respectively.
In a preferred embodiment of the present utility model, the diameter of described preceding bar reduces gradually along the direction away from described connector.
In a preferred embodiment of the present utility model, the constant diameter of described back bar, and the minimum diameter of described preceding bar equals the diameter of described back bar.
Compared to prior art, described wear-resisting drilling equipment of the present utility model is formed with wearing layer at the sidewall of connector, described wearing layer can be formed on the sidewall of described connector by plating, it can strengthen the anti-wear performance of described connector significantly, thereby in production work, do not need often to change, improved operating efficiency, reduced the overall work cost yet.
Description of drawings
In order to be illustrated more clearly in the technical scheme among the utility model embodiment, the accompanying drawing of required use is done to introduce simply in will describing embodiment below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, 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:
Fig. 1 is the structural representation of wear-resisting drilling equipment one preferred embodiment of the utility model.
The specific embodiment
To the technical scheme among the utility model embodiment be clearly and completely described below, obviously, described embodiment only is a part of embodiment of the present utility model, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making all other embodiment that obtain under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model embodiment discloses a kind of wear-resisting drilling equipment, see also Fig. 1, described wear-resisting drilling equipment 100 comprises drill bit 1, drilling rod 2 and connector 3, described connector 3 comprises front end (not indicating), rear end (not indicating) and sidewall (not indicating), the front end of described connector 3 is connected with described drill bit 1, the rear end of described connector 3 is connected with described drilling rod 2, and the sidewall of described connector 3 and is formed with wearing layer 30 on the described sidewall between described front end and described rear end.
Wherein, described wearing layer 30 can be formed on the sidewall of described connector 3 by the electric welding mode, described wearing layer 30 is titanium layer, titanium alloy layer or other scuff resistance material preferably, it can significantly improve the wearability of described connector 3, thereby guarantees the operate as normal life-span of described connector 3.
In the present embodiment, described connector 3 is cylindrical structure, and according to actual needs, described connector 3 also can be the non-constant structure of diameter.
Further, bar 22 and back bar 24 before described drilling rod 2 comprises, described preceding bar 22 are between described connector 3 and described back bar 24, and its two ends are connected with described back bar 24 with described connector 3 respectively.Wherein, the diameter of described preceding bar 22 reduces gradually along the direction away from described connector 3, the constant diameter of described back bar 24, and the minimum diameter of described preceding bar 22 equals the diameter of described back bar 24.
Compared to prior art, described wear-resisting drilling equipment of the present utility model is formed with wearing layer at the sidewall of connector, described wearing layer can be formed on the sidewall of described connector by plating, it can strengthen the anti-wear performance of described connector significantly, thereby in production work, do not need often to change, improved operating efficiency, reduced the overall work cost yet.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model description to do; or directly or indirectly be used in other relevant technical field, all in like manner be included in the scope of patent protection of the present utility model.
