Abstract

The present invention relates to a kind of pipe end and directly spend measurement mechanism, comprise blade, it is characterized in that: the top of described blade is a rigidity level bar, blade be an India rubber bar below, horizon bar two ends are connected with rubber bar two ends respectively by two contour rigid vertical bars; Described rubber bar is provided with a slide block, and described slide block is provided with Vertical surveyors' staff.Novel structure of the present invention is ingenious, simple to operate, safe and reliable, easy to use, and directly can spend the pipe end of oil well pipe very quickly and easily and accurately detect, precision can reach 0.1mm, and detection efficiency is high.Measurement is directly spent in the end that the present invention is applicable to the tubular articles of multiple different size, highly versatile.

Description

Pipe end directly spends measurement mechanism
Technical field
The present invention relates to a kind of oil well pipe size detection measuring appliance, specifically a kind of oil well pipe pipe end directly spends measurement mechanism.
Background technology
The method that current detection oil well pipe pipe end is directly spent longitudinally is positioned on pipe end by an on-deformable straight steel ruler of long thickening, the gap between then being checked by side, and detecting the distance in its maximum gap with clearance gauge in groups, is namely that pipe end is directly spent.The shortcoming of this method is that operation is wasted time and energy, and accuracy of detection is not high.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, there is provided a kind of novel structure cleverly pipe end directly spend measurement mechanism, it is simple to operate, safe and reliable, easy to use, directly can spend very quickly and easily accurately detect the pipe end of oil well pipe.
According to technical scheme provided by the invention: pipe end directly spends measurement mechanism, comprise blade, it is characterized in that: the top of described blade is a rigidity level bar, blade be an India rubber bar below, horizon bar two ends are connected with rubber bar two ends respectively by two contour rigid vertical bars; Described rubber bar is provided with a slide block, and described slide block is provided with Vertical surveyors' staff.
As a further improvement on the present invention, described slide block is semicircle, slide block is provided with the scroll wheel of walking of can rolling on described India rubber bar.
As a further improvement on the present invention, the wheel groove shape of described scroll wheel and the cross sectional shape of rubber bar match.
As a further improvement on the present invention, the length of described blade is 1.5 meters.
As a further improvement on the present invention, 0 scale value of described Vertical surveyors' staff is in below, and the scale value of Vertical surveyors' staff increases from top to bottom successively.
The present invention compared with prior art, advantage is: (1) novel structure of the present invention is ingenious, simple to operate, safe and reliable, easy to use, directly can spend very quickly and easily accurately detect the pipe end of oil well pipe, precision can reach 0.1mm, and detection efficiency is high.(2) measurement is directly spent, highly versatile in the end that the present invention is applicable to the tubular articles of multiple different size.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Fig. 2 is the embody rule situation schematic diagram of the embodiment of the present invention.
Embodiment
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in the figure: the pipe end in embodiment is directly spent measurement mechanism and mainly comprised blade, the top of described blade is a rigidity level bar 1, blade be an India rubber bar 2 below, horizon bar 1 two ends are connected with rubber bar 2 two ends respectively by two contour rigid vertical bars 3; Described rubber bar 2 is provided with a slide block 4, and described slide block 4 is provided with Vertical surveyors' staff 5.
As shown in Figure 1 and Figure 2, in the present invention, described slide block 4 is preferably set to semicircle, slide block 4 is provided with the scroll wheel of walking of can rolling on described India rubber bar 2.The wheel groove shape of described scroll wheel and the cross sectional shape of rubber bar 2 match.
In the embodiment of the present invention, the length of described blade is 1.5 meters; 0 scale value of described Vertical surveyors' staff 5 is in below, and the scale value of Vertical surveyors' staff 5 increases from top to bottom successively, is that H ± 3.18 place makes visible marking (H to refer on blade below between distance) at scale.
It is as follows that the present invention is applied to the embody rule situation detecting oil well pipe:
As shown in Figure 2, India rubber bar 2 is made to be close to the end surface of oil well pipe to be measured, sliding slider 4, Vertical surveyors' staff 5 has an intersection point with the rigidity level bar 1 of blade top, distance between the scale value of the Vertical surveyors' staff 5 corresponding to this intersection point to deduct on blade is below exactly pipe end deviation distance, can find out every segment length (1.5m) scope inner tube maximum deviation distance.
When the content according to american petroleum ANSI APISPEC5CT " sleeve pipe, oil pipe specification " the 9th edition requires to judge whether the straight degree of oil well pipe meets the requirements, then see that the scale corresponding to intersection point of Vertical surveyors' staff 5 and the rigidity level bar 1 of blade top is whether within H ± 3.818mm scope, if within the scope of this, then oil well pipe is directly spent and is met the requirements, if not within the scope of this, then undesirable.
