Abstract

The invention relates to a pipe end straightness measuring instrument for an oil well pipe. The measuring instrument comprises a ruler body, and is characterized in that: placement embedded grooves are formed at two ends of the upper part of the ruler body; a sliding groove is formed between the placement embedded grooves at the two ends along a length direction of the ruler body; a sliding channel is longitudinally formed at the bottom of the sliding groove; one end of the sliding channel is communicated with the sliding groove and the other end of the sliding channel extends to the bottom of the ruler body; a digital display dial indicator is fixed in the placement embedded grooves through the sliding base; the lower end of the digital display dial indicator is provided with a circular rolling contact; and the digital display dial indicator can slide in the sliding groove and the sliding channel between the placement embedded grooves at the two ends. The pipe end straightness measuring instrument is convenient to use and easy to operate and is easily learned and used; the digital dial indicator is adopted for digital display and has clear reading; the pipe end straightness measuring instrument is suitable for measuring the straightness of end parts of various steel pipes in different specifications, and has high generality; and the pipe end straightness measuring instrument has the precision of 0.01mm which is the same as that of the dial indicator, and a resolution ratio of 0.01mm.

Description

Oil well pipe pipe end straightness measuring instrument

Technical field

The present invention relates to a kind of oil well pipe dimension control and use measuring appliance, especially a kind of oil well pipe pipe end straightness measuring instrument.

Background technology

It is vertically to be positioned on the steel pipe pipeline section through the long on-deformable straight steel ruler of thickening of a 1.83m that present existing technology for detection oil well pipe pipeline section is directly spent; Slit between checking through the side then; Using the distance in its maximum slit of clearance gauge detection in groups, promptly is that pipe end is directly spent.

Summary of the invention

The objective of the invention is to overcome the deficiency that exists in the prior art, a kind of oil well pipe pipe end straightness measuring instrument is provided, simple to operate, safe and reliable, easy to use, can effectively directly spend very simply fast and detect pipe end.

According to technical scheme provided by the invention; Said oil well pipe pipe end straightness measuring instrument comprises blade, and characteristic is: the both upper ends thereof at said blade is provided with the placement embedded groove; Length direction along blade between the placement embedded groove at two ends is provided with sliding tray; Bottom at sliding tray vertically is provided with sliding channel, and an end of sliding channel is communicated with sliding tray, and the other end extends to the bottom of blade; In said placement embedded groove, fixedly statistics have shown dial gauge through sliding bottom; Said numeral shows that the lower end of dial gauge is equipped with the circular scrolling contact, and said numeral shows that dial gauge can slide in sliding tray between the placement embedded groove at two ends and sliding channel.

Said rolling contact is positioned at the lower surface of blade.The inner chamber of said sliding tray and the shape of sliding bottom are complementary.On said blade, be provided with a plurality of holes.

The present invention has the following advantages: (1) is easy to use, and is simple to operate, is easy to learn and use to adopt digital dial gauge to carry out numeral demonstration, clear reading; (2) be adapted to various steel pipes, measurement, highly versatile are directly spent in the end of the tubular articles of different size; (3) possess the equal precision of dial gauge, precision reaches 0.01mm, and resolution reaches 0.01mm; (4) directly spend measurement for the oil well pipe pipe end and effectively improved detection efficiency; (5) novelty, practical, keep in repair very convenient and simple simultaneously.

Description of drawings

Fig. 1 is a structural representation of the present invention.

Fig. 2 is the right view of Fig. 1.

Fig. 3 is the right view of blade of the present invention.

Embodiment

Below in conjunction with concrete accompanying drawing the present invention is described further.

Like Fig. 1 ~ shown in Figure 3: oil well pipe pipe end straightness measuring instrument comprises that blade 1, numeral show dial gauge 2, sliding bottom 3, rolling contact 4, hole 5, place embedded groove 6, V-type sliding tray 7, lock-screw 8, sliding channel 9 etc.

The present invention includes blade 1; Both upper ends thereof at said blade 1 is provided with placement embedded groove 6; Length direction along blade 1 between the placement embedded groove 6 at two ends is provided with sliding tray 7; Bottom at sliding tray 7 vertically is provided with sliding channel 9, and an end of sliding channel 9 is communicated with sliding tray 7, and the other end extends to the bottom of blade 1; In said placement embedded groove 6, fixedly statistics have shown dial gauge 2 through sliding bottom 3 and lock-screw 8; Said numeral shows that the lower end of dial gauge 2 is equipped with circular scrolling contact 4, and said numeral shows that dial gauge 2 can slide in sliding tray between the placement embedded groove 6 at two ends 7 and sliding channel 9;

Numeral shows the slip of dial gauge 2 in sliding tray 7 for ease, and the shape of the inner chamber of said sliding tray 7 and sliding bottom 3 is complementary;

For the overall weight that alleviates blade 1 plays firm effect simultaneously, on blade 1, be provided with a plurality of circular ports 5.

About the long nearly 2m of oil well pipe pipe end straightness measuring instrument length of the present invention; This oil well pipe pipe end straightness measuring instrument is when assembling; At first numeral is shown after dial gauge 2 and sliding bottom 3 are assembled and request for utilization is satisfied in its locking and the length below the assurance locked position with lock-screw 8; Numeral is shown that the positions of panels of dial gauge 2 is fit to reading and checks to be advisable and get final product when simultaneously it is installed; Again circular scrolling contact 4 being installed on numeral shows dial gauge 2 lower ends and guarantees and consistently with glide direction satisfy it and can roll smoothly; The good assembly that to assemble then is positioned in the V shape sliding tray 7 on the blade 1 through any placement embedded groove 6 in the two ends of blade 1, and the main effect of circular port 5 is exactly to alleviate the overall weight of blade 1 to play firm effect simultaneously; Can show that dial gauge 2 make zero to its numeral then, the lower plane that makes zero with blade 1 is that zero reference returns to zero, and simultaneously numeral is shown that dial gauge 2 is set to show that maximal value gets final product; At last the oil well pipe pipe end is directly spent measurement mechanism and lie against pipe end; The user of service only needs that numeral is shown that dial gauge 2 usefulness hands exert all one's strength to compress through V shape sliding tray 7 downwards and slides into the other end from an end; This moment, numeral showed that the maximal value that has shown on the dial gauge 2 is exactly the measured straight number of degrees value of pipe end, operated very simple and convenient.

Principle of work of the present invention: it is that numeral is shown that dial gauge 2 is made as desirable reference line and then numeral is shown that circular scrolling contact 4 on the dial gauge 2 rolls in the predetermined distance scope measure numeral and show that jitter values maximum on the dial gauge 2 is the straight degrees of data of pipe end on pipe end on the V of blade 1 shape sliding tray 7 bases that this oil well pipe pipe end is directly spent measurement mechanism.

The present invention is that the content request according to american petroleum ANSI API SPEC 5CT " sleeve pipe, oil pipe standard " the 9th edition designs and improved a kind of pick-up unit it, can effectively directly spend pipe end very simply fast and detect.Can find out the interior deflection of pipe end predetermined distance scope with respect to the maximum between the ideal line plane.
