DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 , a device for automatically measuring the specifications of a pipe rod during the lifting and lowering process of a pipe rod in the oil and gas industry, comprising a base 1, a rotating shaft 12 and a computing system 3 are respectively installed on the top surface of the base 1. It is worth noting that the computing system 3 is electrically connected to the coding sensor 11 and the camera 19 controller, and the information collected by the coding sensor 11 and the camera 19 is transmitted to the computing system 3. Figure 4 , while the camera 19 is taking photos and storing the photos, the photos are synchronously transmitted to the computing system 3 for image processing and comparison. By using the difference between the features of the pipe and its background, the pipe body is first identified, the pixel coordinates of the two ends of the pipe are located, and the pixel coordinates are converted into physical coordinates by implementing the calibrated information, and then the physical length between the two ends of the pipe is calculated, that is, the actual length of the pipe itself. At the same time, through AI learning and industrial vision training, the accuracy of pipe recognition is continuously improved, thereby reducing the probability of misjudgment;

[0023] The top surface of the base 1 is rotatably connected to a swimming system 5, and the base 1 drives the swimming system 5 to rotate through a supporting mechanism. The supporting mechanism includes a plurality of hydraulic rods 6, and the top of each hydraulic rod 6 is fixedly installed with the swimming system 5. The top surface of the base 1 is rotatably connected to a baffle 4, and the swimming system 5 penetrates and is fixedly installed in the baffle 4. It is worth noting that by starting a plurality of hydraulic rods 6, it is convenient to adjust the angle of the swimming system 5, thereby adjusting the insertion angle of the pipe rod;

[0024] One end of the swimming system 5 is slidably connected with a pipe clamp 7, and the pipe clamp 7 controls the extension distance of the pipe clamp 7 through the swimming system 5. A plurality of encoding sensors 11 are symmetrically installed on the top surface of the pipe clamp 7, which are used to accurately measure the displacement of the swimming system 5. Because the lifting and lowering of the pipe rod are synchronously moved with the swimming system 5, the displacement of the swimming system 5 can represent the up and down displacement of the pipe rod and the tool. The measurement division of the encoding sensor 11 can reach 5000 divisions / circle, so the measurement accuracy is very high, and the value can be output in real time, with fast response, easy quantification, sensitivity and reliability. A plurality of support seats 8 are symmetrically installed on the outside of the pipe clamp 7, and both ends of each support seat 8 are slidably connected with rollers 9. A clamping and fixing device 10 is installed in the pipe clamp 7. The clamping and fixing device 10 is convenient for clamping and fixing the pipe rod, and then the movement of the pipe rod is driven by the cooperation of the swimming system 5 and the clamping and fixing device 10, and then the pipe rod is lowered;

[0025] The outer side of the pipe clamp 7 is symmetrically connected to two rotating shafts 12, and the two rotating shafts 12 are driven by an external driving source, thereby driving the assembly seat 13 to rotate, and taking pictures of the pipe rod multiple times, and taking pictures at various angles, is convenient for comparison and error correction. The top surface of each rotating shaft 12 is fixedly installed with an assembly seat 13, and a camera 19 is fixedly installed at the center of the side of each assembly seat 13. A turntable 18 is rotatably connected in each assembly seat 13, and a fill light 17 and a sunshade 20 are fixedly installed on the outer side of each turntable 18. The fill light 17 can improve the light distribution, which is convenient for highlighting the main body and facilitating the camera 19 to take clear pictures of the pipe rod. Each assembly seat 13 drives the turntable 18 to rotate through a driving mechanism, and the driving mechanism The structure includes a motor 14, and the motor 14 is fixedly mounted on the outside of the assembly seat 13. The output shaft of the motor 14 passes through the assembly seat 13 and is installed with a driving gear 15. A driven gear 16 is installed on the turntable 18, and the driving gear 15 is meshed with the driven gear 16. The pitch circle diameter length of the driving gear 15 is smaller than the pitch circle diameter length of the driven gear 16, thereby increasing the transmission ratio, facilitating the precise adjustment of the rotation of the turntable 18, and driving the shading plate 20 to rotate at different angles to block the sunlight. A plurality of lighting lamps 21 are symmetrically installed on the outside of each assembly seat 13. The shading plate 20 is made of metal, and can be made of aluminum alloy. It has good heat dissipation effect and is not light-transmitting.

[0026] When the utility model is used, firstly, the rotation angle of the baffle 4 and the swimming system 5 is adjusted by a plurality of hydraulic rods 6, then the pipe rod is inserted into the pipe clamp 7 and fixed by the clamping and fixing device 10 in the pipe clamp 7, then the pipe clamp 7 is slid by starting the swimming system 5, thereby driving the clamping and fixing device 10 in the pipe clamp 7 to be inserted downward, then the pipe rod is loosened by the clamping and fixing device 10, and the friction between the pipe clamp 7 and the pipe rod is reduced by a plurality of rollers 9, then the pipe clamp 7 is reset by the swimming system 5, and then the pipe rod is fixed again by the clamping and fixing device 10, and the above operation is repeated again to lower the pipe rod, and at the same time, the coding sensor 11 on the pipe clamp 7 can be used to accurately measure the displacement of the swimming system 5, thereby accurately calculating the depth of the lowering of the pipe rod;

[0027] At the same time, when the sunlight is strong, the motor 14 can be started to drive the turntable 18 to rotate, and the rotation angle of the sunshade 20 can be adjusted to block the sunlight, and then the fill light 17 can be started to fill the light for the camera 19, so that the photo is clearer, and it can avoid overexposure resulting in unclear photography of the tube pole;

[0028] The image is then transmitted to the computing system 3, which then locates the pixel coordinates at both ends of the tube and calculates the physical length between the two ends of the tube, that is, the actual length of the tube itself. At the same time, through AI learning and industrial vision training, the accuracy of tube recognition is continuously improved, thereby reducing the probability of misjudgment.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
