[0021] like Figure 1 As shown, an automatic full-length gauging device for oil casing includes a gauging rod 2. The front part of the gauging rod 2 is conical, and the rear part of the gauging rod 2 is cylindrical. A gauging guide rod 7 is connected to the center of the rear end of the gauging rod 2. A clamping wheel 3 is provided at the front end of the gauging guide rod 7, and the clamping wheel 3 supports the gauging guide rod 7.

[0022] The rear end of the guide rod 7 is fitted with a wear-resistant conduit 4. A composite wear-resistant bushing 6 is provided between the guide rod 7 and the wear-resistant conduit 4. The composite protective bushing 6 is made of wear-resistant composite material and is fitted on the guide rod 7 to prevent wear between the guide rod 7 and the wear-resistant conduit 4. The wear-resistant conduit 4 is provided with several oil injection holes 5. Lubricating oil can be injected between the wear-resistant conduit 4 and the guide rod 7 through the oil injection holes 5 to maintain lubrication between the two and reduce wear.

[0023] The lower part of the wear-resistant guide tube 4 is provided with a moving groove 15. The moving groove 15 is elongated and its length is set according to the stroke range of the guide rod 7. A guide rod connecting plate 12 is provided on the lower rear side of the guide rod 7. The guide rod connecting plate 12 extends out of the moving groove 15. A first base 23 is provided below the guide rod connecting plate 12. Steel wire rope rollers 10 are respectively provided at both ends of the first base 23. A steel wire rope 13 is connected between the two steel wire rope rollers 10. The guide rod connecting plate 12 is fixedly connected to the steel wire rope 13. A motor 9 is connected to the steel wire rope rollers 10. The forward and reverse rotation of the motor 9 drives the steel wire rope 13 to move back and forth. Through the connecting action of the guide rod connecting plate 12, the guide rod 7 moves forward or backward in a straight line within the moving groove 15 of the wear-resistant guide tube 4. Several electric turbine screw drive mechanisms 14 are evenly arranged on the first base 23 between the two wire rope rollers 10. The upper end of the electric turbine screw drive mechanism 14 is fixedly connected to the wear-resistant guide tube 4. The functions of the electric turbine screw drive mechanism 14 are: first, to support the entire wear-resistant guide tube 4; and second, to adjust the height of the entire gauging device, thereby adjusting the gauging rod 2, the gauging guide rod 7, and the wear-resistant guide tube 4 to be concentric with the oil casing 1, so as to ensure that the gauging device can be used for all specifications of oil casing.

[0024] A manual screw drive mechanism 18 is provided below the clamping wheel 3. The center height of the guide rod 7 can be adjusted by adjusting the height of the manual screw drive mechanism 18.

[0025] Below the manual screw drive mechanism 18 is a support and shock-absorbing trolley 17, which has rollers. Below the support and shock-absorbing trolley 17 is a limiting platform 19, with limiting blocks 22 at both ends of the limiting platform 19. The support and shock-absorbing trolley 17 has two functions: first, to support the front end of the guide rod 7; and second, to provide shock absorption and buffering when the guide rod 2 enters or exits the oil casing 1. At the same time, the support and shock-absorbing trolley 17 drives the clamping wheel 3 to move back and forth within the limiting platform 19, which can improve the space utilization of the equipment.

[0026] A first photoelectric switch 8 is provided on the rear side of the wire rope roller 10. The function of the photoelectric switch 8 is to detect the movement status of the wire rope roller 10. When the gauging device does not operate due to reasons such as obstruction, the information is transmitted to the control panel and an alarm is triggered.

[0027] A third photoelectric switch 16 and a second photoelectric switch 11 are arranged sequentially on the first base 23 between the two wire rope rollers 10. The function of the third photoelectric switch 16 and the second photoelectric switch 11 is to determine the entire movement stroke of the guide rod 7 by adjusting their positions relative to the guide rod connecting plate 12, and to detect the position of the guide rod 2 by detecting the position of the guide rod connecting plate 12.

[0028] The front side of the limiting platform 19 is provided with a second base 24, and a roller conveyor 21 is provided on the second base 24. The oil sleeve 1 is set on the roller conveyor 21. The rear end of the second base 24 is provided with a fourth photoelectric switch 20. The function of the fourth photoelectric switch 20 is to detect whether the oil sleeve is in place and trigger the entire through-diameter device.

[0029] Working principle: 1. Tooling adjustment: According to the specifications of the oil casing 1, select a suitable bore diameter rod 2 and install it on the bore diameter guide rod 7; Adjust the positions of the third photoelectric switch 16 and the second photoelectric switch 11 so that the distance between them is equal to the travel of the bore diameter bar 2. According to the specifications of the oil casing 1, adjust the height of the electric worm screw drive mechanism 14 and the manual screw drive mechanism 18 so that the bore bar 2 is concentric with the oil casing 1; at the same time, adjust the connection position of the wire rope 13 on the connecting plate 12.

[0030] 2. Workflow: After the tooling is adjusted, the system is powered on. The oil casing 1 is conveyed to the position of the fourth photoelectric switch 20 along the roller conveyor 21, triggering the fourth photoelectric switch 20 to power on. The tooling begins to operate: the motor 9 drives the wire roller 10 to rotate counterclockwise, and the wire rope 13 drives the guide rod connecting plate 12 to move linearly from the second photoelectric switch 11 to the third photoelectric switch 16, driving the gauging bar 2 to enter the oil casing 1 along the support and shock-absorbing trolley 17 and move linearly within the oil casing 1. When the guide rod connecting plate 12 moves to the position of the third photoelectric switch 16, the gauging work is completed. Subsequently, the motor 9 reverses, driving the guide rod connecting plate 12 to return to the position of the second photoelectric switch 11 along a straight line from the position of the third photoelectric switch 16, that is, driving the gauging bar 2 back to the initial position, and the gauging work is completed.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
