Description

Technical Field

[0001] The invention relates to the technical field of oil and gas pipe detection equipment, in particular to an automatic measuring device for pipe threads of oil and gas pipes. Background Art

[0002] As an important component of oil drilling equipment, oil and gas pipes are mostly connected by threads. Therefore, the pipe threads of oil and gas pipes are subjected to the combined effects of multiple forces such as the weight of the pipe, the make-up torque, and the reciprocating motion of the pumping system. If the quality of the pipe threads of oil and gas pipes is unqualified, it is very easy to cause the connection of oil and gas pipes to fail, which in turn causes accidents such as oil and gas leakage or even explosion of the interface.

[0003] At this time, it is necessary to carry out detailed inspection of the threads. Currently, most automatic measuring devices still require personnel to replace materials. The work efficiency of the above process is low, and improper operation by personnel may cause damage to the threads. In response to the above problems, the following solutions are proposed. Summary of the invention

[0005] Preferably, a base is fixedly connected to the outer wall of the bottom plate, a slide groove is provided on the outer wall of the base, a slider is slidably connected to the outer wall of the slide groove, a structural box is fixedly connected to the outer wall of the slider, an electric telescopic rod is fixedly connected to the outer wall of the bottom plate, an end of the electric telescopic rod away from the bottom plate is fixedly connected to the structural box, a circular bracket is fixedly connected to the outer wall of the structural box, an end of the structural frame away from the circular bracket is fixedly connected to a support arm, a plurality of CCD threaded cameras are fixedly connected to the inner wall of the circular bracket, and a CCD internal thread camera is fixedly connected to one end of the support arm away from the structural box.

[0006] Preferably, one end of the pry bar away from the counterweight is rotatably connected to a short bar, the outer wall of the short bar is fixedly connected to a protective frame, the inner wall of the protective frame is fixedly connected to a spring, and the end of the spring away from the protective frame is fixedly connected to the outer wall of the pry bar.

[0007] Preferably, the lower end of the partition is fixedly connected to a connecting plate, the outer wall of the connecting plate is fixedly connected to a belt, the lower end of the connecting plate is fixedly connected to a counterweight, the outer wall of the belt is rotatably connected to the pulley, and the outer wall of the belt is fit-connected to the cross bar.

[0008] Preferably, the lower end of the second partition is fixedly connected with a damping shell, the outer wall of the damping shell is fixedly connected with an extension plate, and the outer wall of the bottom plate is fixedly connected with the second damping shell. In order to solve the problems of slow detection and low detection efficiency of oil and gas pipe detection equipment, a lever mechanism and a partition mechanism are arranged in the equipment. Before use, the bottom plate and the structural frame are installed in the required position, and the power is connected. The transmission shaft is connected through the motor transmission. Several pry bars are arranged on the transmission shaft. A counterweight block is arranged at one end of each pry bar, and the other end is pressed on the extension plate. When the motor rotates clockwise, it drives the transmission shaft. Rotate clockwise, driving the pry bar to rotate clockwise, which will bring the sleeve out of the pry bar. At the same time, the short rod connected to the front end of the pry bar will pop out due to the action of the spring without the obstruction of the partition plate 2, driving the sleeve to leave the inspection table. When the pry bar leaves the extension plate, the partition plate 2 will be set by the damping spring returner of the bottom spring assembly to move the partition plate 2 upward. The partition plate 2 will block the sleeve on the structural frame to make it reach the predetermined position. When the pry bar moves upward to a certain height, it will block the sleeve from leaving the fixed position, making the fixed position vacant, which is convenient for the next sleeve to enter the fixed inspection.

[0009] Preferably, a damping spring returner is fixedly connected to the outer wall of the bottom plate, and the end of the damping spring returner away from the bottom plate is fixedly connected to the inner wall of the damping shell, and the outer wall of the damping spring returner is fit-connected to the inner wall of the damping shell 2, and the end of the belt away from the connecting plate is fixedly connected to the lower end of the damping shell. By utilizing the rising force of the above-mentioned partition 2, when the pry bar leaves the extension plate, because the damping spring returner is provided at the lower end of the partition 2, the damping spring returner will reset upward after the pry bar leaves, driving the partition 2 upward at the same time. At the same time, because a counterweight block 1 is provided at the bottom end of the partition, when the partition two moves upward, the force of the connecting belt disappears, and the partition moves downward because the counterweight block 1 at the bottom end no longer has the force driven by the belt. When the partition two moves upward slowly, the partition slowly moves downward. Because of the slope setting of the structural frame, the sleeve will roll from the partition to the partition two and be blocked by the partition two, so that the sleeves enter the position to be tested one by one, avoiding the error of testing two sleeves at the same time and reducing mechanical failures or inaccurate detection data caused by position errors.

[0010] Preferably, a bracket three is fixedly connected to the outer wall of the bottom plate, a plurality of damping spring rods are fixedly connected to the outer wall of the bracket three, and a straight plate is fixedly connected to the outer wall of the bracket three, and the force of the above-mentioned motor is used to reset the pry bar. When the motor drives the pry bar to rotate counterclockwise, the pry bar is reset downward and drives the extension plate downward. The extension plate is fixedly connected to the damping shell, and a partition two is fixedly connected to the damping shell. A damping spring resetter is fixedly connected to the inner wall of the damping shell. When the pry bar moves downward, it drives the partition two downward. At the same time, the force of the partition two moving downward will drive the belt to move downward. At the same time, the downward movement of the belt will cause the connecting plate fixedly connected to the other end of the belt away from the damping shell to move upward due to the lever principle of the pulley. When the partition two slowly moves downward, the partition will slowly move upward under the drive of the belt. When the partition two is completely lowered, the partition is completely on, the partition will block the subsequent sleeve, and the partition two will be fully opened, which will cause a sleeve that has rolled here before to roll down to the fixed unit at the lower end.

[0011] Preferably, one end of the U-shaped bottom plate is fixedly connected to the U-shaped bottom plate, and the outer walls of the two ends of the U-shaped bottom plate are rotatably connected to the U-shaped clamping plate, and the inner wall of the U-shaped clamping plate is provided with an anti-skid groove, and the outer wall of the anti-skid groove is closely connected to the straight plate. By utilizing the design of the inclination of the above-mentioned structural frame, the sleeve can move downward to reach the U-shaped bottom plate, and by utilizing the force of the sleeve falling from a height, when the sleeve contacts the U-shaped bottom plate, the damping spring rod designed at the bottom end of the U-shaped bottom plate can absorb excess force, and at the same time, the anti-skid groove is rotatably connected to the U-shaped bottom plate at both ends of the U-shaped bottom plate, and the anti-skid groove will be resisted by the straight plate closely connected to the outside to fix the sleeve, preventing the sleeve from being displaced during detection. When the sleeve is fixed, the structural box is moved forward by the electric telescopic rod to detect the internal thread or external thread of the sleeve, thereby improving the detection accuracy of the equipment. At the same time, when the detection camera moves, the partition two will limit the subsequent sleeve from entering the detection area, thereby avoiding obstruction and collision of the front-end detection unit, which affects the detection accuracy of the equipment. The present invention has the following beneficial effects: (1) The present invention aims to solve the problems of slow detection and low detection efficiency of oil and gas pipe detection equipment. A lever mechanism and a partition mechanism are arranged in the equipment. Before use, the bottom plate and the structural frame are installed at the required position and the power is connected. The transmission shaft is connected through the motor transmission. A plurality of pry bars are arranged on the transmission shaft. A counterweight block is arranged at one end of each pry bar, and the other end is pressed on the extension plate. When the motor rotates clockwise, it will drive the transmission shaft to rotate clockwise, drive the pry bar to rotate clockwise, and the casing will be taken out by the pry bar. At the same time, the short rod connected to the front end of the pry bar will pop out due to the action of the spring without the shielding of the second partition, and drive the casing to leave the detection table. When the pry bar leaves the extension plate, the second partition will move upward due to the damping spring resetter set by the bottom spring assembly. At the same time, the second partition will shield the casing on the structural frame that moves downward synchronously to reach the predetermined position. When the pry bar moves upward to a certain height, it will block the casing from leaving the fixed position, so that the fixed position is vacant, which is convenient for the next casing to enter the fixed detection.

[0012] (2) The present invention utilizes the upward force of the above-mentioned partition 2. When the pry bar leaves the extension plate, because a damping spring resetter is provided at the lower end of the partition 2, the damping spring resetter will reset upward after the pry bar leaves, driving the partition 2 upward. At the same time, because a counterweight block 1 is provided at the bottom end of the partition, when the partition 2 moves upward, the force of the connecting belt disappears. The partition moves downward because of the counterweight block 1 at the bottom and the lack of the belt-driven force. When the partition 2 moves slowly upward, the partition moves slowly downward. Because of the slope setting of the structural frame, the sleeve will roll from the partition to the partition 2 and be blocked by the partition 2, so that the sleeves enter the position to be detected one by one, avoiding the error of detecting two sleeves at the same time, thereby reducing mechanical failures or inaccurate detection data caused by position errors.

[0013] (3) The present invention utilizes the force of the above-mentioned motor to reset the pry bar. When the motor drives the pry bar to rotate counterclockwise, the pry bar will drive the extension plate downward when it resets downward. The extension plate is fixedly connected to the damping shell. The damping shell is fixedly connected with partition plate 2. The inner wall of the damping shell is fixedly connected with a damping spring resetter. When the pry bar moves downward, it drives partition plate 2 downward. At the same time, the force of partition plate 2 moving downward will drive the belt to move downward. At the same time, the downward movement of the belt will cause the connecting plate fixedly connected to the other end of the belt away from the damping shell to move upward due to the lever principle of the pulley. When partition plate 2 slowly moves downward, the partition will slowly move upward under the drive of the belt. When partition plate 2 is completely lowered, the partition is completely up and will block the subsequent sleeve. However, when partition plate 2 is fully opened, a sleeve that has rolled here before will roll down to the lower fixed unit.

[0014] (4) The present invention utilizes the design of the above-mentioned structural frame inclination. The sleeve will move downward to reach the U-shaped bottom plate. By utilizing the force of the sleeve falling from a high place, when the sleeve contacts the U-shaped bottom plate, the damping spring rod designed at the bottom end of the U-shaped bottom plate will absorb the excess force. At the same time, the two ends of the U-shaped bottom plate are rotatably connected with anti-skid grooves. When the U-shaped bottom plate drives the anti-skid groove to move downward, the anti-skid groove will be supported by the straight plate connected to the outside, so that the sleeve is fixed to prevent the sleeve from being displaced during detection. When the sleeve is fixed, the structural box is moved forward by the electric telescopic rod to detect the internal or external thread of the sleeve, thereby improving the detection accuracy of the equipment. At the same time, when the detection camera moves, the partition two will limit the subsequent sleeves from entering the detection area to avoid obstruction and collision of the front-end detection unit, thereby affecting the detection accuracy of the equipment.

[0021] The end of the pry bar 23 away from the counterweight 24 is rotatably connected to a short rod 25, the outer wall of the short rod 25 is fixedly connected to a protection frame 26, the inner wall of the protection frame 26 is fixedly connected to a spring 27, and the end of the spring 27 away from the protection frame 26 is fixedly connected to the outer wall of the pry bar 23.

[0022] The lower end of the partition 31 is fixedly connected to a connecting plate 32, the outer wall of the connecting plate 32 is fixedly connected to a belt 33, the lower end of the connecting plate 32 is fixedly connected to a counterweight block 34, the outer wall of the belt 33 is rotatably connected to a pulley 37, and the outer wall of the belt 33 is fittedly connected to a cross bar 36.

[0023] The partition assembly 4 also includes a damping shell 42 fixedly connected to the lower end of the partition 2 41, an extension plate 43 is fixedly connected to the outer wall of the damping shell 42, and a damping shell 2 45 is fixedly connected to the outer wall of the bottom plate 1. In order to solve the problem of slow detection and low detection efficiency of oil and gas pipe detection equipment, a lever mechanism 2 and a partition mechanism 3 are arranged in the equipment. Before use, the bottom plate 1 and the structural frame 11 are installed in the required position, and the power is connected. The transmission shaft 22 is connected through the motor 21. A plurality of pry bars 23 are arranged on the transmission shaft 22. A counterweight block is arranged at one end of each pry bar 23, and the other end is pressed on the extension plate 43. When the motor rotates clockwise, it will drive the transmission shaft 22 to rotate clockwise. The movement drives the pry bar 23 to rotate clockwise, which will bring out the sleeve 112. At the same time, the short rod 25 rotatably connected to the front end of the pry bar 23 will pop out under the action of the spring 27 without the obstruction of the partition 2 41, driving the sleeve 112 to leave the inspection table. When the pry bar 23 leaves the extension plate 43, the partition 2 41 will be arranged at the bottom spring assembly. The damping spring returner 44 will make the partition 2 41 move upward. The partition 2 41 will block the sleeve 112 on the structural frame 11 to make it reach a predetermined position. When the pry bar 23 moves upward to a certain height, it will block the sleeve 112 from leaving the fixed position, making its fixed position vacant, so as to facilitate the next sleeve 112 to enter the fixed inspection.

[0024] For example 2, please refer to Figure 8 - Fig.10 The present invention is an automatic measuring device for oil and gas pipe threads. On the basis of the first embodiment, a damping spring returner 44 is fixedly connected to the outer wall of the bottom plate 1, and the end of the damping spring returner 44 away from the bottom plate 1 is fixedly connected to the inner wall of the damping shell 42. The outer wall of the damping spring returner 44 is closely connected to the inner wall of the damping shell 2 45, and the end of the belt 33 away from the connecting plate 32 is fixedly connected to the lower end of the damping shell 42. By utilizing the rising force of the above-mentioned partition 2 41, when the pry bar 23 leaves the extension plate 43, because the damping spring returner 44 is provided at the lower end of the partition 2 41, the damping spring returner 44 will reset upward after the pry bar 23 leaves, driving When partition 2 41 moves upward, because a counterweight block 34 is provided at the bottom end of partition 31, when partition 2 41 moves upward, the force connecting belt 33 disappears, and partition 31 loses the force driven by belt 33 because of the counterweight block 34 at the bottom, which causes partition 31 to move downward. When partition 2 41 moves upward slowly, partition 31 moves downward slowly. Because of the slope setting of the structural frame 11, the sleeve 112 rolls from partition 31 to partition 2 41 and is blocked by partition 2 41, so that the sleeves 112 enter the position to be detected one by one, avoiding the error of detecting two sleeves 112 at the same time, and reducing mechanical failure or inaccurate detection data caused by position error.

[0025] A bracket 3 51 is fixedly connected to the outer wall of the bottom plate 1, and a plurality of damping spring rods 52 are fixedly connected to the outer wall of the bracket 3 51. A straight plate 55 is fixedly connected to the outer wall of the bracket 3 51. The force of the motor 21 is used to reset the pry bar 23. When the motor drives the pry bar 23 to rotate counterclockwise, the extension plate 43 is driven downward when the pry bar 23 is reset. The extension plate 43 is fixedly connected to the damping shell 42. The partition 2 41 is fixedly connected to the damping shell 42. A damping spring resetter 44 is fixedly connected to the inner wall of the damping shell 42. When the pry bar 23 moves downward, the partition 2 41 is driven downward. Downward, at the same time, the force of the partition 2 41 moving downward will drive the belt 33 to move downward. At the same time, the downward movement of the belt 33 will cause the connecting plate 32 fixedly connected to the other end of the belt 33 away from the damping shell 42 to move upward due to the lever principle of the pulley 37. When the partition 2 41 slowly moves downward, the partition 31 will slowly move upward under the drive of the belt 33. When the partition 2 41 is completely lowered, the partition 31 is completely up, and the partition 31 will block the subsequent sleeve 112. However, when the partition 2 41 is fully opened, a sleeve 112 that has rolled here before will roll downward to the lower fixed unit.

[0026] The end of the damping spring rod 52 away from the bracket three 51 is fixedly connected to the U-shaped bottom plate 53, and the outer walls of the two ends of the U-shaped bottom plate 53 are rotatably connected to the U-shaped clamping plate 54. The inner wall of the U-shaped clamping plate 54 is provided with an anti-skid groove 56, and the outer wall of the anti-skid groove 56 is closely connected with the straight plate 55. By utilizing the design of the inclination of the above-mentioned structural frame 11, the sleeve 112 will move downward to reach the U-shaped bottom plate 53. By utilizing the force of the sleeve 112 falling from a high place, when the sleeve 112 contacts the U-shaped bottom plate 53, the damping spring rod 52 designed at the bottom end of the U-shaped bottom plate 53 will absorb the excess force, and at the same time, the two ends of the U-shaped bottom plate 53 are rotated. The dynamic connection is provided with an anti-skid groove 56. When the U-shaped bottom plate 53 drives the anti-skid groove 56 to move downward, the anti-skid groove 56 will be resisted by the straight plate 55 connected externally, so that it fixes the sleeve 112 to prevent the sleeve 112 from moving during detection. When the sleeve 112 is fixed, the structural box is moved forward by the electric telescopic rod 111 to detect the internal or external thread of the sleeve 112, thereby improving the detection accuracy of the equipment. At the same time, when the detection camera moves, the partition 2 41 will limit the subsequent sleeve 112 from entering the detection area to avoid obstruction and collision of the front-end detection unit, thereby affecting the detection accuracy of the equipment.

[0027] A specific application of this embodiment is as follows: before use, the base plate 1 and the structural frame 11 are installed at the desired positions, and the power is connected, the sleeve 112 is evenly placed on the structural frame 11, and the sleeve 112 is moved forward by the inclination of the structural frame 11 itself, and the motor 21 installed on the base plate 1 is rotated to connect the transmission shaft 22, and a plurality of pry bars 23 are arranged on the transmission shaft 22, and a counterweight is arranged at one end of each pry bar 23, and the other end is pressed on the extension plate 43. When the motor rotates clockwise, it will drive the transmission shaft 22 to rotate clockwise, and drive the pry bar 23 to rotate clockwise, so that the sleeve 112 is pried. The rod 23 is brought out, and at the same time, the short rod 25 rotatably connected to the front end of the pry bar 23 will pop out under the action of the spring 27 without the obstruction of the partition 24, driving the sleeve 112 to leave the inspection table. After the pry bar 23 leaves the extension plate 43, the partition 241 will respond to the damping spring returner 44 of the bottom spring assembly to move the partition 241 upward. The partition 241 will block the sleeve 112 on the structural frame 11 to make it reach a predetermined position. When the pry bar 23 moves upward to a certain height, it will block the sleeve 112 from leaving the fixed position, making its fixed position vacant, which is convenient for the next sleeve 112 to enter the fixed inspection.

[0028] By utilizing the upward force of the above-mentioned partition 2 41, when the pry bar 23 leaves the extension plate 43, because the damping spring resetter 44 is provided at the lower end of the partition 2 41, the damping spring resetter 44 will reset upward after the pry bar 23 leaves, driving the partition 2 41 upward. At the same time, because the counterweight block 1 34 is provided at the bottom end of the partition 31, when the partition 2 41 is upward, the force of the connecting belt 33 disappears, and the partition 31 loses the force driven by the belt 33 because of the counterweight block 1 34 at the bottom, which will cause the partition 31 to move downward. When the partition 2 41 slowly moves upward, the partition 31 slowly moves downward. Because the slope setting of the structural frame 11, the sleeve 112 will roll from the partition 31 to the partition 2 41 and be blocked by the partition 2 41, so that the sleeves 112 enter the position to be detected one by one, avoiding the error of detecting two sleeves 112 at the same time, reducing mechanical failures or inaccurate detection data caused by position errors.

[0029] The motor 21 is used to reset the lever 23. When the motor drives the lever 23 to rotate counterclockwise, the lever 23 is reset downward and drives the extension plate 43 downward. The extension plate 43 is fixedly connected to the damping housing 42. The damping housing 42 is fixedly connected with a partition plate 2 41. The inner wall of the damping housing 42 is fixedly connected with a damping spring resetter 44. When the lever 23 moves downward, the partition plate 2 41 is driven downward. At the same time, the force of the partition plate 2 41 moving downward drives the belt 33 to move downward. When the belt 33 moves downward, due to the lever principle of the pulley 37, the connecting plate 32 fixedly connected to the other end of the belt 33 away from the damping shell 42 moves upward. When the partition 2 41 slowly moves downward, the partition 31 will slowly move upward under the drive of the belt 33. When the partition 2 41 is completely lowered, the partition 31 is completely up, and the partition 31 will block the subsequent sleeve 112. However, when the partition 2 41 is fully opened, a sleeve 112 that has rolled here before will roll downward to the lower fixed unit.

[0030] By utilizing the design of the inclination of the above-mentioned structural frame 11, the sleeve 112 will move downward to reach the U-shaped bottom plate 53. By utilizing the force of the sleeve 112 falling from a height, when the sleeve 112 contacts the U-shaped bottom plate 53, the damping spring rod 52 designed at the bottom end of the U-shaped bottom plate 53 will absorb the excess force. At the same time, the two ends of the U-shaped bottom plate 53 are rotatably connected with anti-skid grooves 56. When the U-shaped bottom plate 53 drives the anti-skid grooves 56 to move downward, the anti-skid grooves 56 will be supported by the straight plate 55 connected to the outside, so that the sleeve 112 is fixed to prevent the sleeve 112 from being displaced during detection. When the sleeve 112 is fixed, the structural box is moved forward by the electric telescopic rod 111 to detect the internal or external threads of the sleeve 112, thereby improving the detection accuracy of the equipment. At the same time, when the detection camera moves, the partition 2 41 will limit the subsequent sleeve 112 from entering the detection area to avoid obstruction and collision of the front-end detection unit, thereby affecting the detection accuracy of the equipment.
