Because the drilling rod is with the rotatory moment of torsion transmission in ground to drive drilling string and drill bit rotation and carry out work, and weld between body and the joint and form, consequently, when the axiality deviation of whole bull stick was too big, can lead to drilling equipment's life to descend and even major drilling accident appears, consequently, need detect the axiality (the dislocation degree) of drilling rod, prevent the production of above-mentioned problem.
In the existing detection mode of the drill rod,
such as: the CN102607382A tubular petroleum drilling tool coaxiality on-line measuring device is characterized in that rollers are respectively arranged on a horizontal plane and a vertical plane on an angle frame, a drill rod is arranged on the rollers and can rotate, and the coaxiality of the rotating rod is detected through a measuring rod contact of a dial indicator;
also, for example, CN114623751a is a device and method for measuring angular deviation of drill rod, the coaxiality of the rotating drill rod is detected by three dial indicators.
However, in the above detection method, the detection accuracy of the dial indicator is not provided to be low, the detected drill rod needs to rotate, and the detected product may affect the detection result during or after the rotation process, so that the detection accuracy is deviated.
Therefore, the present inventors have further studied this and developed a misalignment detection device, which has been developed.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a dislocation degree detection device can improve the axiality detection precision to parts such as drilling rod class.
In order to achieve the above purpose, the technical solution of the present invention is as follows:
a misalignment measuring device comprises
The brackets are arranged at intervals and used for supporting the drill rod;
the contact sensors are arranged around the drill rod;
and the moving mechanism is driven by the contact type sensor and moves horizontally along the setting direction of the drill rod.
Through the contact type sensor, at the male joint or female joint department of drilling rod, select two positions, measure two coordinate values (X0, Y0), (X1, Y1), confirm a straight line according to two points, find out the data (X2 ', Y2 ') on the coaxial line through two point data that measure, select a position on the body of choice, measure (X2, Y2), find out the distance difference that point (X2 ', Y2 ') reaches point (X2, Y2) and be the dislocation degree, compare in the present roll type detection method, the utility model discloses a scheme is the detection volume under static state, and the moving mechanism drives detection device and moves and only calculates the coordinate for the value, does not carry out real-time detection in the moving process, and adopted the contact type sensor that measurement accuracy is higher, furthest's reduction detection error.
Further, the contact sensor is a contact digital displacement sensor.
The contact type digital displacement sensor is a Japanese Keynes GT-12K.
Further, the moving mechanism comprises a mounting substrate, the contact sensor is arranged on the mounting substrate, and the mounting substrate is arranged on the sliding rail through the moving seat.
Further, the touch sensors are distributed in a cross shape on the mounting substrate.
The coordinate position is accurately calculated by four-point contact.
Furthermore, a groove is formed in the position, relative to the bracket, of the mounting substrate, and the groove is used for accommodating the passing of the bracket when the mounting substrate moves.
Furthermore, a V-shaped groove is formed in the top of the bracket and used for lifting the drill rod.
Further, a manipulator is arranged above the drill rod and used for taking and placing the drill rod.
Further, after the drill rod is conveyed to the bracket through the robot arm, the drill rod is measured through the contact sensor, after the measurement is completed, the moving mechanism drives the contact sensor to return to the standby position, the comparison data is qualified or not, the information is fed back to the robot arm, and the drill rod is taken away from the bracket through the robot arm.
The above-described approach can be applied to similar rod-like members and is not limited to drill rods.
After the scheme is adopted, compared with the prior art, the utility model, have following advantage:
compared with the existing detection technology and mode, the method has higher detection precision and has the capability of automatic detection by comparing the calculated theoretical value with the actual detection value.
