Abstract
The utility model relates to a high-torsion-resistant double-shoulder drill pipe joint boring hole length measuring instrument. The length measuring instrument is characterized in that, the length measuring instrument comprises a connection rod and a locating rod, the locating rod is connected onto the connection rod vertically and can move left and right, a fastening pin is arranged between the locating rod and a measuring rod sleeve and used for fastening and fixing the locating rod and the measuring rod sleeve. The surface of the connection rod is equipped with scale values. The surface of the front end of the connection rod is a conical surface. The length measuring instrument is simple, ingenious and reasonable in structure, easy to operate, safe, reliable, convenient to use, and can measure length of a boring hole rapidly and effectively.
Description
Technical field
The utility model relates to a kind of high twisting-resistance double-circular-bead drilling rod joint check measuring appliance, is a kind of high twisting-resistance double-circular-bead drilling rod joint bore hole length measuring instrument specifically.
Background technology
Along with the more and more harshness of oil, natural gas extraction environment, structural requirement to drill pipe sub is also more and more higher, high twisting-resistance double-circular-bead drilling rod joint is widely used, this joint female joint end is processed with bore hole, for avoiding bore hole and male joint screw thread to interfere, therefore must measure bore hole length.
Shown in Fig. 1 is a kind of high twisting-resistance double-circular-bead drilling rod joint, and the box thread end of this joint is processed with bore hole, and while detecting this bore hole length, general pit gauge or the vernier caliper etc. of adopting, are all difficult to measure position accurately, thus the precision that impact is measured.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of high twisting-resistance double-circular-bead drilling rod joint bore hole length measuring instrument is provided, it is simple in structure, ingenious, reasonable, simple to operate, safe and reliable, easy to use, can detect bore hole length very fast and effectively.
The technical scheme providing according to the utility model: high twisting-resistance double-circular-bead drilling rod joint bore hole length measuring instrument, it is characterized in that: comprise connecting rod and backstay, described backstay is vertically connected on connecting rod and can moves left and right, and between backstay and sounding rod sleeve, is provided with the locking pin for they are locked; Described rod surface is provided with scale value, and connecting rod front-end surface is a conical surface.
As further improvement of the utility model, described connecting rod front-end surface is 30 ° of conical surfaces.
As further improvement of the utility model, described backstay is provided with long slot bore, and backstay moves left and right on connecting rod by long slot bore, and described locking pin is contained in long slot bore.
The utility model compared with prior art, has the following advantages: (1) the utility model is simple in structure, ingenious, reasonable, simple to operate, safe and reliable, easy to use, clear reading; (2) the utility model can accurately be located bore hole terminal position, therefore can accurately measure the length of bore hole.
Accompanying drawing explanation
Fig. 1 is the two bead drill pipe female joint structural representations of high moment of torsion.
Fig. 2 is the structural representation of the utility model embodiment.
Fig. 3 is the use constitutional diagram of the utility model embodiment.
Embodiment
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As shown in the figure: the high twisting-resistance double-circular-bead drilling rod joint bore hole length measuring instrument in embodiment is mainly made up of connecting rod 2, backstay 3 and locking pin 4 etc.
Described backstay 3 is provided with long slot bore, and backstay 3 moves left and right on connecting rod 2 by long slot bore; Between backstay 3 and sounding rod sleeve, be provided with the locking pin 4 for they are locked, described locking pin 4 is contained in long slot bore; Described connecting rod 2 surfaces are provided with scale value, and connecting rod 2 front-end surface are 30 ° of conical surfaces 1.
The course of work of the present utility model is as follows:
As shown in Figure 3, first make the end face of backstay 3 be close to the shoulder of the box 5 that needs are measured, the upper surface of connecting rod 2 is close to bore hole inside surface 6, move left and right connecting rod 2, make 30 ° of conical surfaces 1 of connecting rod 2 be close to 30 ° of withdrawing faces 7 of bore hole, carry out position by locking pin 4 and fix, take out measuring instrument, read rule reading and be the length of bore hole.
The utility model can be measured the bore hole length of the high twisting-resistance double-circular-bead drilling rod joint at a series of 30 ° of withdrawing angles, and versatility is high, and cost is low, easy to use.
