Description
Technical Field
The invention relates to the technical field of a method for judging the full-length drift diameter of a seamless steel pipe, in particular to a method for ensuring the full-length drift diameter of the seamless steel pipe.
Background
In the technical field of the whole seamless steel pipe, the full-length drift diameter is a permanent technical problem, the manufacturing industry and the working efficiency of an oil field are seriously restricted, and the whole seamless steel pipe industry urgently needs to develop a technology for ensuring the full-length drift diameter detection of the seamless steel pipe.
At present, drift diameter devices in the seamless steel pipe industry are basically mechanical drift diameters, a drift diameter gauge mechanical device is composed of drift diameter gauges and drift diameter rods, and based on the drift diameter rods of one specification, a large number of drift diameter gauges of different specifications are matched, so that the stroke error of the drift diameter gauges inevitably occurs, and the real-time stroke of the drift diameter gauges is inconsistent with the actual stroke; in the face of the difficult problem of on-site non-full-length drift diameter, different specifications of steel pipes can be matched to manufacture drift diameter gauges, and the manufacturing cost and the management cost of the drift diameter gauges are greatly increased, so that the drift diameter gauges do not have the implementation possibility.
The seamless steel pipe industry generally adopts two processes to realize the full-length drift diameter of a steel pipe:
1. an oil cylinder is adopted to drive an encoder to position the steel pipe, and then the length of the steel pipe is measured by utilizing an opposite-emitting grating;
2. the drift diameter rod is matched with an encoder to detect the advancing distance of the drift diameter gauge in real time, and when the distance is larger than the length of the steel pipe measured in the first procedure, the control system defaults the full-length drift diameter of the steel pipe to be completed.
Practice proves that the full-length drift diameter detection method has poor effect and the success rate is about 60 percent.

Furthermore, the error elimination is based on the elimination of the matching gap error between the drift diameter gauge and the drift diameter rod, field spare parts and maintenance force are fully utilized, matched shaft sleeves are manufactured according to different specifications of the drift diameter gauges, and the idle stroke of the drift diameter gauge is thoroughly eliminated by the application of the matched shaft sleeves, so that the mechanical stroke error of the drift diameter gauge is eliminated.
Furthermore, the laser length measurement adopts a laser sensor fixing device to ensure that the laser center is positioned within the tolerance adjustment range of the inner diameter center of the steel pipe, the laser beam is adjusted to be horizontally parallel to the steel pipe, and the sensor detects the movement distance of the drift diameter gauge in real time; when the drift diameter station material detection device transmits a signal to the control system, the control system monitors the actual running distance of the drift diameter gauge in real time, compares the laser measurement value with the length of the steel pipe in real time, if the laser measurement value is larger than the length of the steel pipe, the program judges that the drift diameter is qualified, otherwise, the program judges that the drift diameter is unqualified, locks the equipment action and triggers the alarm.
The invention has the beneficial effects that: 1. the invention breaks through the restriction of conventional thinking, adopts non-contact measurement, realizes the real-time position detection and feedback of the drift diameter gauge, monitors the drift diameter quality in the steel pipe in real time, and has the drift diameter effect obviously superior to the conventional contact type mechanical drift diameter detection effect; compared with a mechanical drift diameter method, the non-contact measurement has two main characteristics: error elimination and laser length measurement are carried out, and non-omission detection of the full-length drift diameter machine of the steel pipe in the production line is realized; 2. the invention fully utilizes the field environment, and realizes 100 percent of full-length drift diameter of the seamless steel pipe in a low-cost and quick implemented thinking mode; the non-contact full-length drift diameter detection method realizes the technical breakthrough of full-length drift diameter detection in the field of seamless steel pipes, greatly reduces the on-site operation and maintenance cost, greatly improves the labor efficiency and greatly reduces the working intensity of on-site personnel.
