Description

Technical Field

[0001] This utility model relates to the field of oil casing repair technology, and in particular to a positioning mechanism for casing reinforcement pipe. Background Technology

[0002] Pipeline patching is one of the core technologies in the field of pipeline maintenance and repair. It mainly refers to the technical means of covering the defective area and forming a firm fit with the original pipeline by adding or reinforcing sealing components to address local defects in pipelines such as corrosion, perforation, cracks, and thinning of the wall. This restores the structural strength and sealing performance of the pipeline, prevents media leakage, and extends the service life of the pipeline.

[0003] The existing methods for positioning the sleeve reinforcement pipe mostly rely on manual reinforcement. This method makes it difficult to flexibly adjust the repair components according to the actual location of the pipe to be reinforced, which can easily lead to positioning deviations. This results in a difference between the reinforcement pipe and the damaged sleeve, affecting the repair quality. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a positioning mechanism for sleeve repair reinforcement tubes, aiming to improve the existing positioning of sleeve repair reinforcement tubes, where the repair reinforcement tubes deteriorate from the damaged sleeves, affecting the quality of repair.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning mechanism for a sleeve-mounted reinforcement tube, comprising a base, a support plate fixedly connected to the top of the base, a motor fixedly connected to one side of the support plate, a lead screw rotatably connected to the bottom of the base, the top end of the lead screw fixedly connected to the output end of the motor, support rods symmetrically fixedly connected to the bottom of the base, a base plate fixedly connected to the bottom end of the support rods, the bottom end of the lead screw rotatably connected to the inside of the base plate, a slider threadedly connected to the outer wall of the lead screw, a patch seat fixedly connected to the top of the slider, a second sealing ring fixedly connected to the top of the patch seat, the middle of the slider, the patch seat, and the second sealing ring slidably connected to the outer wall of the support rod, and a feeding assembly installed at the bottom of the base.

[0006] By adopting the above solution, the rotation of the motor drive shaft drives the rotation of the lead screw, which in turn drives the sliding of the slider, thereby causing the repair seat, the first sealing ring, and the second sealing ring to slide. At the same time, the sliding of the second sealing ring causes the extension and retraction of the feeding assembly, which delivers the repair cement into the interior of the repair seat, thereby filling the space formed by the first sealing ring and the pipe, thus completing the repair.

[0007] Preferably, the feeding assembly includes a first piston cylinder, the top of which is fixedly connected to the bottom of the base, a first piston ring is fixedly connected to the outer wall of the top of the first piston cylinder, a first limiting ring is fixedly connected to the inner wall of the bottom of the first piston cylinder, a second piston ring is slidably connected to the inner wall of the first piston cylinder, a second piston cylinder is fixedly connected to the bottom of the second piston ring, a second limiting ring is fixedly connected to the inner wall of the bottom end of the second piston cylinder, and the diameter of the second piston cylinder is smaller than the diameter of the first piston cylinder.

[0008] Preferably, the inside of the subsidy seat is fixedly connected to several diversion pipes, and the inside of the diversion pipes is fixedly connected to the bottom of the second piston cylinder.

[0009] Preferably, the side wall of the slider is fixedly connected to a plurality of connecting posts, and one end of each connecting post is fixedly connected to a first sealing ring, the first sealing ring being located below the subsidy seat.

[0010] Preferably, a protective sleeve is fixedly connected to the bottom of the base, the bottom end of the protective sleeve is fixedly connected to the top of the second sealing ring, the protective sleeve is located outside the first piston cylinder, and the protective sleeve is made of a bellows.

[0011] Preferably, a plurality of storage boxes are fixedly connected to the bottom of the first sealing ring, an electric push rod is fixedly connected inside the storage box, and an arc-shaped scraper is fixedly connected to the output end of the electric push rod.

[0012] Preferably, a control panel is fixedly connected to the top of the base, an ultrasonic detector is fixedly installed on the side wall of the subsidy seat, and several electric heating rods are fixedly connected to the side wall of the subsidy seat.

[0013] Preferably, the surface of the base has a plurality of mounting holes.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the rotation of the drive shaft of the motor drives the rotation of the lead screw, which in turn drives the sliding of the slider, thereby driving the sliding of the repair seat, the first sealing ring and the second sealing ring. At the same time, the sliding of the second sealing ring drives the extension and retraction of the feeding component. The feeding component delivers the repair cement into the interior of the repair seat, thereby filling the space formed by the first sealing ring, the second sealing ring and the pipe, thus completing the repair.

[0015] 2. In this utility model, the extension and retraction of the arc-shaped scraper is controlled by an electric push rod. When the slider slides down, the arc-shaped scraper is pressed tightly against the inside of the pipe to remove the oil stains adhering to the inner wall of the pipe and improve the bonding strength of the repair cement. When the slider slides up, the arc-shaped scraper is retracted into the storage box to prevent the arc-shaped scraper from damaging the newly repaired cement. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Reference Figures 1-3This utility model provides an embodiment of a positioning mechanism for a sleeve patch reinforcement tube, comprising a base 1, a support plate 2 fixedly connected to the top of the base 1, a motor 3 fixedly connected to one side of the support plate 2, a lead screw 4 rotatably connected to the bottom of the base 1, the top end of the lead screw 4 fixedly connected to the output end of the motor 3, support rods 5 symmetrically fixedly connected to the bottom of the base 1, a base plate 6 fixedly connected to the bottom end of the support rods 5, the bottom end of the lead screw 4 rotatably connected to the inside of the base plate 6, a slider 7 threadedly connected to the outer wall of the lead screw 4, a patch seat 8 fixedly connected to the top of the slider 7, a second sealing ring 10 fixedly connected to the top of the patch seat 8, the middle of the slider 7, the patch seat 8 and the second sealing ring 10 slidably connected to the outer wall of the support rod 5, and a feeding assembly installed at the bottom of the base 1.

[0020] Specifically, the base 1 is used to install the support plate 2, the support plate 2 is used to install the motor 3, the support rod 5 is used to prevent the slider 7 from rotating, and the bottom plate 6 is used to limit the sliding range of the slider 7. When this device is needed, the motor 3 is started, the drive shaft of the motor 3 rotates and drives the lead screw 4 to rotate, which in turn drives the slider 7 to slide on the outer wall of the lead screw 4 and the support rod 5. The sliding of the slider 7 drives the sliding of the patch seat 8, which in turn drives the sliding of the second sealing ring 10. When the slider 7 slides to the vicinity of the pipe to be repaired, the motor 3 is stopped, so that the patch seat 8 is located near the pipe to be repaired. At this time, the repair cement is delivered into the patch seat 8 through the feeding component. Since the diameter of the patch seat 8 is smaller than that of the second sealing ring 10, the repair cement will fill the space formed by the second sealing ring 10 and the pipe. After the repair cement solidifies, the motor 3 is started to retract the slider 7 upward, which in turn causes the second sealing ring 10 to detach from the repair site, so that the solidified repair cement remains in the place to be repaired, thus completing the repair. This improves the positioning of the existing sleeve patch reinforcement pipe, which has a difference between the patch reinforcement pipe and the damaged sleeve, affecting the repair quality.

[0021] Reference Figure 3 and Figure 4 The feeding assembly includes a first piston cylinder 11, the top of which is fixedly connected to the bottom of the base 1. A first piston ring 12 is fixedly connected to the outer wall of the top of the first piston cylinder 11. A first limiting ring 13 is fixedly connected to the inner wall of the bottom of the first piston cylinder 11. A second piston ring 24 is slidably connected to the inner wall of the first piston cylinder 11. A second piston cylinder 25 is fixedly connected to the bottom of the second piston ring 24. A second limiting ring 26 is fixedly connected to the inner wall of the bottom end of the second piston cylinder 25. Several diversion pipes 14 are fixedly connected inside the auxiliary seat 8. The inside of the diversion pipes 14 is fixedly connected to the bottom of the second piston cylinder 25. A protective sleeve 18 is fixedly connected to the bottom of the base 1. The bottom end of the protective sleeve 18 is fixedly connected to the top of the second sealing ring 10. The protective sleeve 18 is located outside the first piston cylinder 11 and is made of corrugated pipe.

[0022] Specifically, the inner diameter of the first piston cylinder 11 is equal to the outer diameter of the second piston cylinder 25. The first piston ring 12 and the second piston ring 24 are used to prevent repair cement from leaking out of the first piston cylinder 11 and the second piston cylinder 25. The first limiting ring 13 and the second limiting ring 26 are used to limit the sliding of the second piston cylinder 25 and prevent the second piston cylinder 25 from sliding out completely. The protective sleeve 18 is used to prevent liquid from corroding the feeding assembly. The protective sleeve 18 is made of corrugated pipe, which can extend or contract synchronously with the feeding assembly. When repair is needed, the downward sliding of the slider 7 drives the second piston ring 24 to slide downward inside the first piston cylinder 11. This causes the second piston cylinder 25 to slide downwards, extending the feeding assembly. After the repair is completed, the slider 7 slides upwards, causing the second piston ring 24 to slide upwards inside the first piston cylinder 11, which in turn causes the second piston cylinder 25 to slide upwards, causing the second piston cylinder 25 to retract into the interior of the first piston cylinder 11, thereby shrinking the feeding assembly. Multiple sets of diversion pipes 14 are arranged in a grid pattern inside the patch seat 8. When the repair cement flows into the patch seat 8 from the feeding assembly, the cement is evenly distributed on the pre-reserved pipe openings on the side wall of the repair seat through the diversion pipes 14, which prevents uneven distribution of the repair cement during repair.

[0023] Reference Figure 3 and Figure 5 The side wall of the slider 7 is fixedly connected to several connecting posts 19. One end of the connecting post 19 is fixedly connected to a first sealing ring 9. The first sealing ring 9 is located below the subsidy seat 8. The bottom of the first sealing ring 9 is fixedly connected to several storage boxes 15. One end of an electric push rod 16 is fixedly connected inside the storage box 15. The other end of the electric push rod 16 is fixedly connected to an arc-shaped scraper 17. The top of the base 1 is fixedly connected to a control panel 21. The top of the second sealing ring 10 is fixedly connected to an ultrasonic detector 22. The side wall of the subsidy seat 8 is fixedly connected to several electric heating rods 23. The surface of the base 1 is provided with several mounting holes 20.

[0024] Specifically, the first sealing ring 9 and the second sealing ring 10 are made of hydrogenated nitrile rubber. The mounting hole 20 is used to quickly install this device with the flange of the pipe or other devices. The ultrasonic detector 22 is used to detect damage inside the pipe that needs to be repaired. The electric heating rod 23 is used to heat the cement to accelerate its solidification. The control panel 21 is used to control the extension and retraction of the electric push rod 16, the inspection of the ultrasonic detector 22, and the heating of the electric heating rod 23. The storage box 15 is used to store the arc-shaped scraper 17. The connecting column 19 is used to connect the slider 7 and the first sealing ring 9. When repair is needed, the extension of the electric push rod 16 is controlled so that the side wall of the arc-shaped scraper 17 is close to the inner wall of the pipe. At this time, the motor 3 is started to drive the slider 7 to slide, which in turn drives the arc-shaped scraper 17 to scrape downward to remove the oil stains attached to the pipe and improve the bonding strength of the repair cement. After cleaning, the electric push rod 16 is controlled to retract and the arc-shaped scraper 17 is put into the storage box 15 to prevent the arc-shaped scraper 17 from scraping off the cement at the repair site after the repair is completed.

[0025] Working principle: When the device is needed, the motor 3 is started. The motor 3 drives the slider 7 to slide downwards, which in turn drives the patch seat 8 to slide downwards, thereby driving the first sealing ring 9 and the second sealing ring 10 to slide. At the same time, the downward sliding of the first sealing ring 9 drives the arc-shaped scraper 17 to slide downwards, achieving the effect of cleaning the oil stains on the inner wall of the pipe by the arc-shaped scraper 17, thereby improving the bonding strength of the repair cement. In addition, the downward sliding of the slider 7 drives the second piston cylinder 25 to slide downwards, conveying the repair cement into the diversion pipe 14 inside the patch seat 8 through the feeding component. The repair cement will fill the space formed by the first sealing ring 9, the second sealing ring 10 and the pipe, completing the repair.

[0026] Once the repair is complete, the electric push rod 16 is retracted, causing the arc-shaped scraper 17 to retract into the storage box 15. At this time, the motor 3 is started, and the slider 7 slides upward, causing the second piston cylinder 25 to slide upward, so that the second piston cylinder 25 retracts into the interior of the first piston cylinder 11, thereby shrinking the feeding assembly. At the same time, the slider 7 slides upward, causing the first sealing ring 9 and the second sealing ring 10 to detach from the repair site, so that the solidified repair cement remains in the area that needs repair, thus completing the repair.

[0027] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires. Furthermore, appropriate controllers should be selected and electrically connected to the control panel 21, ultrasonic detector 22, electric heating rod 23, and electric push rod 16 according to the actual situation to meet control requirements. Specific connections and control sequences should refer to the working principle described above, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The above mainly introduces the working principle and process; further explanation of electrical control is not provided.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
