Background
At present, in the process of measuring the size of a drill nozzle on an oil drilling operation site, a nozzle gauge measuring tool is used for measuring the drill nozzle, the size cannot be visually displayed after an equivalent tool leaves the measured nozzle, and under the condition that the drill is large in size or the drill is inconvenient to move in a limited space, the conventional nozzle gauge cannot measure or read the size inconveniently, so that the difficulty is brought to the drill nozzle size measuring operation.
Disclosure of Invention
The invention overcomes the defects in the prior art, the existing nozzle gauge can directly read the reading on the nozzle gauge when measuring the nozzle size, but the nozzle of a drill bit is generally embedded into the drill bit, and the problem that the drill bit cannot be measured or the reading is inconvenient to move under the condition that the size of the drill bit is larger or the drill bit is in a limited space is provided.
The purpose of the invention is realized by the following technical scheme.
A drill bit nozzle size measuring tool for the petroleum drilling field comprises a main rod, an auxiliary rod and a trapezoidal sheet,
the mobile jib adopts the cross section to be "native" type rod structure the mobile jib locating hole has been seted up on the upper portion of mobile jib, vice pole runs through the mobile jib locating hole with the mobile jib links to each other the lower part of mobile jib forms a size sign to in the size of utilizing size sign direct reading nozzle the middle part of trapezoidal piece forms one and extends to "T" type groove of trapezoidal piece bottom from trapezoidal piece top, "T" type inslot, just the mobile jib can be followed "T" type groove reciprocates to the best size of nozzle measurement is selected in the realization.
A method for using the size measuring tool of the drill nozzle for the petroleum drilling field, while measuring, the lower bottom edge of the trapezoid slice is flush with the lower end surface of the main pole, insert the measuring tool into nozzle to be measured, make the auxiliary lever support the front edge of the spray nozzle, push the trapezoid slice to the spray nozzle inside until it can't be pushed, at this moment, the correspondent size on the size label of the main pole is the size of the spray nozzle;
tan(α/2)＝((x-b)/2)/c
x＝2c*tan(α/2)+b
wherein, b: length of upper base of trapezoidal piece, c: measure the distance of the lower base of trapezoidal piece and mobile jib lower extreme face, x: size of drill bit nozzle, α: the included angle of the extension lines of the two side edges of the trapezoidal piece.
The invention has the beneficial effects that: the tool solves the problems of the existing nozzle gauge, and the size of the drill bit nozzle can be obtained by measuring the distance between the lower bottom edge of the trapezoidal piece and the lower end surface of the main rod and converting after the included angle of the extension lines of the two side edges of the trapezoidal piece and the length of the upper bottom edge of the trapezoidal piece are known by adopting the principle of indirect measurement; the problem that the measurement cannot be carried out in a limited space is solved by setting a combined transfer scale value of the main rod and the auxiliary rod; meanwhile, the trapezoidal piece measurement and main rod reading modes are set, the problem of inconvenient reading is solved, and the problem that the size of the measured nozzle can be visually displayed even if the tool leaves the measured nozzle is also solved.

Detailed Description
The technical solution of the present invention is further illustrated by the following specific examples.
Example one
A drill bit nozzle size measuring tool for the petroleum drilling field comprises a main rod 1, an auxiliary rod 2 and a trapezoidal piece 3,
Example two
A method for using the size measuring tool of the spray nozzle of the bit for the petroleum drilling field, while measuring, insert the measuring tool into spray nozzle to be measured with the lower bottom edge of the trapezoid slice 3 and lower end of the main boom 1 being flush, make the auxiliary boom 2 support the front edge of the spray nozzle, push the trapezoid slice 3 to the spray nozzle inwards until it can't be pushed, at this moment, the correspondent size on the size label 4 of the main boom 1 is the size of spray nozzle;
tan(α/2)＝((x-b)/2)/c
x＝2c*tan(α/2)+b
wherein, b: length of upper base of trapezoidal piece, c: measure the distance of the lower base of trapezoidal piece and mobile jib lower extreme face, x: size of drill bit nozzle, α: the included angle of the extension lines of the two side edges of the trapezoidal piece.
The measuring tool adopts the principle of indirect measurement, and after the included angle of the extension lines of the two side edges of the trapezoidal piece 3 and the length of the upper bottom edge of the trapezoidal piece 3 are known, the size of the drill nozzle can be obtained by measuring the distance between the lower bottom edge of the trapezoidal piece 3 and the lower end surface of the main rod 1 and converting the distance.
Spatially relative terms, such as "upper," "lower," "left," "right," and the like, may be used in the embodiments for ease of description to describe one element or feature's relationship to another element or feature as illustrated in the figures. It will be understood that the spatial terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "lower" can encompass both an orientation of upper and lower. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
Moreover, relational terms such as "first" and "second," and the like, may be used solely to distinguish one element from another element having the same name, without necessarily requiring or implying any actual such relationship or order between such elements.
