A driving wheel 7 is arranged in the water pool 1 through a rotating shaft A11; one end of the rotating shaft A11 extends to the outside of the water pool 1 and is provided with a transmission gear 22; the outside of the water pool 1 is provided with a driving motor 20 (see the attached figure 2 in the specification); the driving motor 20 is connected with a transmission gear 22 through a transmission chain 21; when the driving motor 20 works, the driving wheel 7 can be driven to synchronously rotate by the transmission chain 21 and the transmission gear 22.
A mounting frame 9 is fixedly arranged in the water tank 1 above the driving wheel 7 (see the attached figures 1 and 3 in the specification); a rotating shaft B12 is movably arranged on the mounting rack 9 through an adjusting slide hole 10 and a movable bearing seat 14; a driven wheel 8 is fixedly arranged on the rotating shaft B12; a buffer spring 13 is arranged in the adjusting slide hole 10 above the movable bearing seat 14. The driven wheel 8 is thus mounted through the mounting frame 9 and the buffer spring 13 with the aim of: when the device works, after the oilfield tubular rod 19 enters between the driven wheel 8 and the driving wheel 7, the driven wheel 8 can always enable the oilfield tubular rod 19 to be attached and connected with the driving wheel 7 under certain pressure under the action of the elastic force of the buffer spring 13, so that the oilfield tubular rod 19 can be conveyed in a double-roller extrusion conveying mode under the matching of the driven wheel 8 in the rotating process of the driving wheel 7.
Extrusion ring grooves 15 are formed in the circumferential surface of the driving wheel 7 and the circumferential surface of the driven wheel 8; the arc radian of the extrusion ring groove 15 is consistent with the radian of the circumferential surface of the oilfield tubular rod 19; an anti-skid cushion layer is arranged inside the extrusion ring groove 15 (see the attached figure 3 in the specification). The purpose of thus providing the extrusion ring groove 15 is: firstly, make the during operation, action wheel 7 and follow driving wheel 8 can keep laminating with oil field pipe pole 19 through extrusion annular 15 and be connected to reach and make action wheel 7 and keep sufficient area of contact from between driving wheel 8 and the oil field pipe pole 19, avoid area of contact not enough, take place the problem of "skidding" between action wheel 7 and follow driving wheel 8 and the oil field pipe pole 19. Secondly, the risk of 'slipping' of the driving wheel 7 and the driven wheel 8 is further reduced by utilizing the characteristic of large friction coefficient of the anti-slipping cushion layer.
A measuring ring 4 is arranged on one side of the driver 3 (see the attached figure 1 in the specification); a plurality of ultrasonic measurement probes 6 are mounted in the measuring ring 4 in a divergent manner (see fig. 3 in the specification). The ultrasonic measuring probe 6 is a purchased device produced by Shantou ultrasonic instrument factory and is of the type CTS-23A.

In addition, when the ultrasonic pulse sent by the ultrasonic measuring probe 6 passes through water (coupling agent) and reaches the oil field pipe rod 19, a part of ultrasonic pulse signals are reflected by the outer pipe wall of the oil field pipe rod 19; another part of the ultrasonic pulse signal will be reflected by the inner pipe wall of the oilfield tubular rod 19; the ultrasonic measurement probe 6 records the time of the ultrasonic pulse signals reflected twice; setting the time from the emission of the ultrasonic pulse to the reception of the signal reflected from the outer pipe wall of the oilfield tubular rod 19 as t 1; setting the signal time from the emission to the reception of the ultrasonic pulse reflected from the inner pipe wall as t 2; the propagation speed of the ultrasonic pulse in water is v 1; the propagation speed of the ultrasonic pulse in the oilfield tubular rod 19 is v 2; setting the wall thickness of the pipe wall of the oil field pipe rod 19 as S; the outer diameter of the oilfield tubular rod 19 is S outside; the inner diameter of the oilfield tubular rod 19 is within S; the distance from the end of the ultrasonic measuring probe 6 to the center of the measuring ring 4 is S; oilfield tubular string 19 has a length L.
The calculation formula of the length, the outer diameter, the inner diameter and the wall thickness of the oilfield tubular rod 19 is as follows:
wall thickness S = v2 (t 2-t 1)/2 of oilfield tubular rod 19
Outside diameter of oilfield tubular rod 19 sExtra = Szhong-v 1 × t1/2
Inside diameter sbin = sbout-S of oilfield tubular stem 19
Length L = v3 × t3 of oilfield tubular rod 19
In the above calculation, the value in S may be obtained by actual measurement; v2 and v1 are known conditions; t1 and t2 are parameters recorded by the ultrasonic measuring probe 6; thus, the formula and the calculation principle are programmed by using MATLAB software in a PLC central processing unit; when the ultrasonic measuring probe 6 transmits the t1 and t2 signals to the PLC central processing unit, the PLC central processing unit can calculate the length, the outer diameter, the inner diameter and the wall thickness of the oilfield tubular rod 19 by the program.
Because the inside of the measuring ring 4 is provided with a plurality of ultrasonic measuring probes 6, after each ultrasonic measuring probe 6 gives a signal to the PLC central processing unit, the PLC central processing unit can calculate the outer diameter, the inner diameter and the wall thickness of the oil field pipe rod 19 in all directions; then the PLC central processing unit can simulate and compare the shape of the oil field pipe rod 19 by the prior art, so that the purpose of measuring and detecting the oil field pipe rod 19 can be achieved.

The purpose of thus assembling the limit roller 17 is: in the process that the oilfield tubular rod 19 penetrates through the limiter 2, each limiting roller 17 can keep rolling connection with the oilfield tubular rod 19 under the action of the buffer spring 13, and further the oilfield tubular rod 19 can penetrate through the center of the limiter 2; the eccentric problem of the oilfield tubular rod 19 is avoided.
The circumference of the limiting roller 17 is in an hourglass-shaped structure (see the attached figure 4 in the specification). The surface radian of the limiting roller 17 is consistent with that of the oilfield tubular rod 19; after the arrangement, the surface of the limiting roller 17 can be kept in fit connection with the oilfield tubular rod 19; so that the limit roller 17 can provide enough support for the oilfield tubular rod 19 under the elastic force of the buffer spring 13.
