Embodiment
The present invention is directed to a kind of identification marking of means of attachment uniqueness that is used to so that the system and method that parts can be identified and follow the tracks of at its whole life period.The present invention relates to install identification dish, described identification dish comprises unique identification marking, in the chamber of described identification marking in being formed at the main body of parts.Although the present invention has the widespread use that is applied to various parts, the portion's section that is drilling rod by described component representation in the context of this article.In context, by the wall analogy of drilling rod, be the body of parts.
See figures.1.and.2, the recognition system of one embodiment of the present of invention comprises: identification dish 10, this identification dish has upper side 11 and the bottom surfaces 12 of almost parallel.At least upper side 11, preferably also has bottom surfaces 12, be provided with identification marking or the sign of one or more uniquenesses, the identification marking of described uniqueness or sign corresponding to 10 installations of identification dish maybe by the identity of unique portion section of the drilling rod being installed to or analog.Identification marking can comprise for example machine readable code labeling 13.Substitute machine code-reading mark 13 be or except machine readable code labeling 13, identification marking can comprise the alphabet-numeric playing identifier 14 that can directly be read by people.
In one exemplary embodiment of the present invention, identification dish 10 is the plane bodies that formed by No. 316 stainless steels.In addition, identification dish 10 comprises circular structure ideally, and this circular structure has the diameter of about an inch and the thickness of approximately 1/10th inches between upper side 11 and bottom surfaces 12.Yet, will be recognized that identification dish 10 can be formed by other suitable durable materials, and can comprise other structures and/or size.
As shown in Figure 3, machine readable code labeling 13 comprises matrix Quick Response Code ideally.Quick Response Code has some advantages with respect to traditional one-dimensional bar code, comprising: allow the obviously more information of storage or data in given region.For example, typical one-dimensional bar code is restricted to 14 character datas, and Quick Response Code can represent a nearly hundreds of character data.In one exemplary embodiment of the present invention, in Quick Response Code mark 13, store about 60 character datas.
Quick Response Code also allows data redundancy.Therefore,, if a part for Quick Response Code mark 13 is damaged, the data that represented by this Quick Response Code can be read from the not broken parts of Quick Response Code mark.When coded article (such as portion's section of drilling rod) stand situation that risk that code signing is damaged increases, the data redundancy that Quick Response Code mark 13 provides is particular importance.
Although described in this article code signing 13, comprise Quick Response Code, should be understood that, system of the present invention is not limited to this, and code signing can comprise any available code, includes but not limited to traditional one-dimensional bar code.
Code signing 13 and identifier 14(are if you are using) preferably by laser engraving on identification dish 10.Although do not depart from the situation of principle of the present invention, can use these marks are applied to other modes on identification dish 10, but laser engraving is preferred, because it can make mark cut a little the material of identification dish, this provides improved durability and readability concerning mark.The mark forming by laser engraving also has the high degradation resistant to chemicals running in typical drill-well operation, can't be subject to the impact of the high temperature and high pressure that drilling rod in use may stand.Although preferably code signing 13 is not arranged on the peripheral part office of identification dish, the concrete setting that code signing 13 and optional identifier 14 are located at least upper side 11 of identification dish 10 is not crucial.
The identification marking that comprises code signing 13 and optional identifier 14 represents discrete and unique code, and it can be used to 10 installations of identification dish maybe by each independent portion section of the drilling rod being installed to or analog.Each user of system of the present invention can determine by the represented particular data of identification marking.As mentioned above, for code signing 13, the data storage capacities of Quick Response Code used allows storage mass data, can utilize this ability by the mode of any expectation.
In a preferred embodiment of the invention, at least a portion representative that comprises code signing 13 and the identification sign of optional identifier 14 is for identifying 10 installations of dish maybe by unique sequence number of each section of the drilling rod being installed to or analog.By this way, can set up and preserve a comprehensive database, for recording the complete history of portion's section of drilling rod, this history can conduct interviews by this sequence number.Therefore,, when the portion's section from drilling rod is read sequence number, can from database, access at an easy rate the expectation information about drilling rod.The data storage capacities of Quick Response Code mark 13 also allows the information of the portion's section about drilling rod to be directly stored on drilling rod, so that it can be read and be obtained by scanner immediately, and without the access database of long-range preservation for example.
As totally illustrated in Fig. 4 and Fig. 5, in one embodiment of the present of invention, each identification dish 10 is associated by identification dish being embedded in chamber 16 with portion's section of drilling rod 15, and described chamber extends in the main body or wall of drilling rod from the outside surface of drilling rod.As shown in Figure 5, the degree of depth of chamber 16 is preferably greater than the thickness of identification dish 10, makes the upper side 11 of identification dish sink to outside surface below.Upper side 11 is positioned at the protection identification marking that arranges of outside surface below and avoids abrasion and corrosion, thereby the lasting readability in the length of life of drilling rod contributes to identification marking.
In one embodiment of the invention, identification dish 10 is fastened in chamber 16 by means of being arranged on the jointing material 17 between the bottom of chamber and the bottom surfaces 12 of identification dish.Alternately, can adopt for identification dish 10 being fastened on to other modes of chamber 16, as long as the identification marking in upper side 11 does not have covered live.Moreover preferably identification dish 10 can be removed from chamber, so that the identification marking in upper side 11 becomes in unreadable situation, can from chamber 16, remove identification dish, and can read the same tag in identification dish bottom surfaces 12.Then, the identification dish 10 of replacing can be fastened in chamber 16, to guarantee the lasting tracking to drilling rod 15.
In a preferred embodiment of the invention, chamber 16 is at upper side 11 upper openings of identification dish 10.Although some chips may be deposited in this part of chamber 16 in the use procedure of drilling rod, be easy to remove these chips before can or reading identifier 14 at scan code mark 13.And in fact the existence of chip can protect the upper side 11 of identification dish 10.Although be not preferred, chamber 16 can identification coil 10 above be filled with for example transparent material or removable connector.
It should be pointed out that the relatively little chamber 16 in the wall that gets out or be otherwise formed into drilling rod can not damage intensity or the durability of drilling rod or reduce its effectiveness.Some variations that stand the position of chamber 16, and within the scope of the free tailoring of user or manufacturer; Yet chamber is arranged on ideally in position frayed and that corrode, to make full use of the function of feature of the present invention.For example, chamber 16 can be arranged in the box cupling or tool-joint of drilling rod.
Except the portion's section for drilling rod and analog provide a kind of firmly and and shielded recognition system; system of the present invention also provides a kind of simple and reliable means, and whether the wearing and tearing that these means experience for portion's section of monitoring drilling rod should take out of service from service to can determine this section.In use, the surface of portion's section of drilling rod is worn, and when the diameter that is monitored region of drilling rod is reduced to predetermined minimum dimension, can not re-use this section of drilling rod.
Therefore, according to one embodiment of present invention, the degree of depth that chamber 16 is got out approximates identification dish 10 and adds that drill rod abrasion allows the thickness in district.By this way, the distance between the outside surface of drilling rod and the upper side 11 of identification dish is by the degree of depth of the admissible region that equals to wear and tear.In the use procedure of drilling rod, along with drill rod abrasion, wearing and tearing allow that district will reduce gradually, and the diameter of drilling rod reduces.As shown in Figure 6, because the upper side 11 of the cross-sectional structure of the drilling rod identification dish 10 that is circle is flat, the erosion of drilling rod exposes the middle body in upper side 11 before frayed the periphery edge of identification dish.Therefore,, when portion's section of drilling rod may wear to the degree that must take out of service from service at it, it is readable that identification marking remains.Therefore, utilize system of the present invention, the wearing and tearing of portion's section of monitoring drilling rod can be reliably, carry out visually, and do not need the diameter of actual measurement drilling rod.
A lot of modification and alternative embodiment are within the scope of the invention.In a kind of modification, from the bottom surfaces 12 of identification dish 10, can omit identification marking.In another kind of modification, identification marking can carved or otherwise be applied on label 18 thin, preferable alloy, and this label is attached to the upper side 11 of identification dish 10, as shown in FIG. 7.
At Fig. 8 and Fig. 9, show another embodiment of recognition system of the present invention.In the present embodiment, identification dish 10 is maintained in chamber 16 by annular lip 20.After being positioned in chamber 16, identification dish 10 forms this lip 20.In addition, lip 20 is configured to only cover the periphery of identification dish 10, so that it will remain on identification dish reliably in chamber 16 and does not block the identification marking being positioned in upper side 11.In addition, lip 20 can form the bottom that district W is allowed in the wearing and tearing that make the top part of lip be positioned adjacent to drilling rod 15.Therefore,, by using, along with the surface of drilling rod 15 is worn, the exposure of the top part of lip 20 will provide drilling rod to reach its wear allowance and should give the visual indication of replacing.
