Description

Technical Field

[0001] This utility model relates to the field of protective frame technology, specifically a safety casing protective frame for oil drilling. Background Technology

[0002] Drilling casing is mainly used to support the wellbore during and after drilling to ensure the drilling process and the normal operation of the entire oil well after completion. The sucker tubing primarily transports oil and gas from the bottom of the well to the surface. Due to varying geological conditions and complex downhole stress states, tensile, compressive, bending, and torsional stresses act on the tubing, placing high demands on its quality. Damage to the casing for any reason can lead to reduced production or even the abandonment of the entire well. Therefore, drilling casing cannot be placed arbitrarily to avoid being stepped on or bumped by machinery. To better protect drilling casing, a safety casing protection frame for oil drilling is proposed.

[0003] For example, the casing placement frame for drilling disclosed in the authorization announcement number CN221439126U includes a base frame, the base frame includes a fixing unit and a power unit, the fixing unit includes a support rod, a top frame, a drilling casing and a pad, and the power unit includes a fixing rod, a stepper motor, a threaded rod, a casing push plate, a pusher plate, an auxiliary wheel, a support plate and a casing placement plate.

[0004] Although it achieves the use of threaded rod and fixed rod in combination, the stepper motor drives the threaded rod to rotate. During the rotation, the sleeve push plate moves, so that the push plate fixed on one side of the sleeve push plate pushes out the sleeve, which has a convenient effect. The fixed rod is provided with a sliding groove, which can be used to protect the threaded rod and also facilitate the movement of the sleeve push plate. Through the use of push plate and sleeve push plate in combination, the sleeve push plate is moved horizontally by the threaded rod, saving manpower to remove the sleeve. Through the use of wheel groove, sliding groove and drilling sleeve in combination, the inner wall of wheel groove is equipped with auxiliary wheel to assist in pushing the sleeve in.

[0005] However, the existing protective frame does not solve the problem that it is not conducive to the linkage expansion clamping and fixing of the sleeve during use, nor to the comprehensive cleaning of the sludge adhering to the sleeve surface. This is not conducive to the protection of the sleeve and the prevention of sludge corrosion, which affects the safety of the protection. Utility Model Content

[0006] The purpose of this utility model is to provide a safety casing protection frame for oil drilling, so as to solve the problems mentioned in the background art, which are not conducive to the linkage and outward expansion clamping and fixing of the casing and the comprehensive cleaning of the sludge adhering to the casing surface, which is not conducive to the protection of the casing and the prevention of casing corrosion by sludge, thus affecting the safety of protection.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A safety casing protection frame for oil drilling includes a placement box and a support frame. The placement box contains multiple sets of support frames spaced at equal intervals. Each support frame has a lifting frame at its top. A second servo motor is mounted on the side wall of each support frame. A sleeve is mounted on the output end of each second servo motor. An electric push rod is installed inside each sleeve. A second push arm is mounted on the output end of each electric push rod. A moving block is mounted on the end of each second push arm away from the electric push rod. Three sets of linkage blocks are spaced at equal intervals on the side wall of each moving block, and the linkage blocks are movably connected to the moving blocks. A clamping arm is movably mounted on the end of each linkage block away from the moving block.

[0009] Optionally, each of the clamping arms is provided with a hinge shaft on its side wall, and the clamping arm is movably connected to the sleeve through the hinge shaft.

[0010] Optionally, each sleeve is provided with a sleeve body on its outside, and the sleeve body is slidably connected to the support frame.

[0011] Optionally, an integrated frame is provided inside the top of the placement box, and a sliding rod is provided inside the placement box on one side of the integrated frame, and the sliding rod is connected to the integrated frame.

[0012] Optionally, two sets of hydraulic rods are symmetrically installed on the top of the placement box. Each hydraulic rod has a first push arm installed at its output end, and the first push arm is connected to the integrated frame and the slide rod, respectively.

[0013] Optionally, a lead screw is movably mounted inside the integrated frame, and a first servo motor is provided on the side wall of the integrated frame, with the output end of the first servo motor connected to the lead screw.

[0014] Optionally, the surface of the lead screw is fitted with a threaded sleeve, and the threaded sleeve is threadedly connected to the lead screw. A spiral frame is provided on the side wall of the threaded sleeve, and the spiral frame is slidably connected to the slide rod. A water spray frame and an air spray frame are respectively installed at the bottom end of the spiral frame.

[0015] Optionally, an air pump is provided at the top of the placement box, and a second flexible hose is installed at the output end of the air pump, and the second flexible hose is connected to the air jet frame.

[0016] Optionally, a water tank is provided at the top of the placement box on one side of the air pump, and a first flexible hose is installed at the output end of the water tank, and the first flexible hose is connected to the water spray frame.

[0017] Optionally, a PLC controller is provided on the side wall of the placement box, and the output terminal of the PLC controller is electrically connected to the input terminal of the water tank, air pump, hydraulic rod, electric push rod, and second servo motor.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the protective frame not only realizes the linkage outward expansion clamping and fixing of the sleeve and the comprehensive cleaning of the sludge adhering to the surface of the sleeve, which facilitates the protection of the sleeve and avoids the sleeve from being corroded by sludge, thus extending the service life of the sleeve, but also improves the safety of the protection.

[0019] The used sleeve is placed on the support frame, and the sleeve is pushed to move and fit onto the surface of the sleeve. The electric push rod drives the second push arm to move, the second push arm drives the moving block to move, the moving block drives the linkage block to rotate, and the linkage block drives the clamping arm to rotate around the hinge axis, so that the three sets of clamping arms rotate outward synchronously, so that the clamping arms contact the inner wall of the sleeve and clamp and fix the sleeve, thereby completing the placement of the sleeve. The placement box protects it, and the clamping and fixing also prevents the sleeve from being displaced by external forces. It realizes the linkage outward expansion clamping and fixing of the sleeve, which facilitates the protection of the sleeve.

[0020] Because the casing being placed is a used casing, its outer surface is covered with dirt. A hydraulic rod drives the first push arm downwards, which in turn moves the integrated frame, slide bar, return frame, water spray frame, and air spray frame downwards, bringing them close to the casing body's surface. Then, the high-pressure water pump inside the water tank is activated, pumping the cleaning solution through the first flexible hose into the water spray frame. The cleaning solution is then sprayed out through the water spray frame, forming a high-pressure water jet that washes away the dirt from the casing body's surface. Simultaneously, a second servo motor drives the sleeve to rotate, which in turn rotates the casing body, bringing other parts of the casing body into the water jet position for a comprehensive cleaning of the casing body's surface. Once a portion of the casing body's surface has been cleaned... Afterwards, the first servo motor drives the lead screw to rotate, which in turn moves the return frame through the threaded sleeve. The return frame then moves the water spray frame and air spray frame laterally above the casing body, moving them to other parts of the first servo motor for cleaning. Simultaneously, the air pump is turned on, pumping air into the air spray frame through the second flexible hose. The air is then sprayed through the air spray frame onto the cleaned casing body surface to dry it. This process is repeated to complete the cleaning and drying of the entire casing body. The cleaned dirt and wastewater are discharged through the drain port at the bottom of the placement box, achieving a comprehensive cleaning of the sludge adhering to the casing surface, preventing sludge corrosion, extending the casing's service life, and improving the safety of protection.

[0035] like Figures 1 to 5As shown, an embodiment of this utility model provides a safety casing protection frame for oil drilling, including a placement box 1 and a support frame 7. The placement box 1 has multiple sets of support frames 7 arranged at equal intervals inside. Each support frame 7 has a lifting frame 27 at its top. A second servo motor 26 is installed on the side wall of each support frame 7, serving as the power drive. A sleeve 19 is installed at the output end of each second servo motor 26, and an electric push rod 20 is installed inside each sleeve 19, also serving as the power drive. The output of the electric push rod 20... Each end is equipped with a second push arm 21. The end of the second push arm 21 away from the electric push rod 20 is provided with a moving block 22. The side wall of the moving block 22 is provided with three sets of linkage blocks 23 at equal intervals. The linkage blocks 23 are movably connected to the moving block 22. The end of the linkage block 23 away from the moving block 22 is movably equipped with a clamping arm 24. The side wall of the clamping arm 24 is provided with a hinge shaft 25. The clamping arm 24 is movably connected to the sleeve 19 through the hinge shaft 25. The outside of the sleeve 19 is provided with a sleeve body 8. The sleeve body 8 is slidably connected to the lifting frame 27.

[0036] In this utility model, the PLC controller 2 is a Siemens S7-200, which is existing technology. Therefore, its internal structure, working principle, and connection and control method with the electrical components in this application will not be described in detail. The used sleeve is placed on the support frame 27, and the sleeve is pushed to move and fit onto the surface of the sleeve 19. The electric push rod 20 is opened, and the electric push rod 20 drives the second push arm 21 to move. The second push arm 21 drives the moving block 22 to move. The moving block 22 drives the linkage block 23 to rotate. The linkage block 23 drives the clamping arm 24 to rotate around the hinge shaft 25, so that the three sets of clamping arms 24 rotate outward synchronously, so that the clamping arms 24 contact the inner wall of the sleeve and clamp and fix the sleeve, thereby completing the placement of the sleeve. The placement box 1 protects it, and clamping and fixing it can also prevent the sleeve from being displaced by external force. The linkage outward expansion clamping and fixing of the sleeve is realized, which facilitates the protection of the sleeve.

[0037] An integrated frame 10 is provided inside the top of the placement box 1, and a slide bar 9 is provided inside the placement box 1 on one side of the integrated frame 10, and the slide bar 9 is connected to the integrated frame 10.

[0038] Two sets of hydraulic rods 11 are symmetrically installed on the top of the placement box 1. The hydraulic rods 11 serve as power drives. The output end of each hydraulic rod 11 is equipped with a first push arm 12, and the first push arm 12 is connected to the integrated frame 10 and the slide rod 9 respectively.

[0039] A lead screw 16 is movably installed inside the integrated frame 10. A first servo motor 18 is provided on the side wall of the integrated frame 10. The first servo motor 18 plays the role of power drive, and the output end of the first servo motor 18 is connected to the lead screw 16.

[0040] A threaded sleeve 17 is fitted on the surface of the lead screw 16 and is threadedly connected to the lead screw 16. A loop frame 13 is provided on the side wall of the threaded sleeve 17 and is slidably connected to the slide rod 9. A water spray frame 14 and an air spray frame 15 are respectively installed at the bottom of the loop frame 13. An air pump 4 is provided at the top of the placement box 1. The air pump 4 plays a power driving role. A second flexible hose 6 is installed at the output end of the air pump 4 and is connected to the air spray frame 15.

[0041] A water tank 3 is installed at the top of the placement box 1 on one side of the air pump 4. A first flexible hose 5 is installed at the output end of the water tank 3 and is connected to the water spray frame 14. A PLC controller 2 is installed on the side wall of the placement box 1 and the output end of the PLC controller 2 is electrically connected to the input end of the water tank 3, the air pump 4, the hydraulic rod 11, the electric push rod 20, and the second servo motor 26.

[0042] Because the casing used was covered in dirt, the hydraulic rod 11 was opened, causing the first push arm 12 to move downwards. The first push arm 12 then moved the integrated frame 10, slide bar 9, return frame 13, water spray frame 14, and air spray frame 15 downwards, bringing the water spray frame 14 and air spray frame 15 close to the surface of the casing body 8. Then, the high-pressure water pump inside the water tank 3 was turned on, pumping the cleaning fluid from the water tank 3 through the first flexible hose 5 into the water spray frame 14. High-pressure water jets are sprayed from the spray gun 14 to wash away the dirt on the surface of the casing body 8. Simultaneously, the second servo motor 26 is activated, driving the sleeve 19 to rotate. Through the sliding engagement between the casing body 8 and the support frame 27, the sleeve 19 rotates the casing body 8, bringing other parts of the casing body 8 into the water jet position for a thorough cleaning of its surface. Once a portion of the casing body 8's surface has been cleaned... Then, the first servo motor 18 is turned on, which drives the lead screw 16 to rotate. With the lead screw 16 and the threaded sleeve 17 connected by threads, and with the sliding cooperation between the return frame 13 and the slide rod 9, the lead screw 16 drives the return frame 13 to move through the threaded sleeve 17. The return frame 13 drives the water spray frame 14 and the air spray frame 15 to move laterally above the casing body 8, so as to move the water spray frame 14 and the air spray frame 15 to other parts of the first servo motor 18 and clean them. At the same time, the air pump 4 is turned on, and the air pump 4 pumps gas into the air spray frame 15 through the second flexible hose 6. The gas is sprayed out through the air spray frame 15 onto the cleaned surface of the casing body 8 to dry it. After repeating the above operation, the cleaning and drying operation of the entire casing body 8 can be completed. The mud and sewage washed off are discharged through the drain port at the bottom of the placement box 1, which realizes the comprehensive cleaning of the sludge adhering to the surface of the casing, avoids the casing from being corroded by sludge, extends the service life of the casing, and improves the safety of protection.

[0043] The working principle of the technical solution provided by this utility model is as follows: The used sleeve is placed on the support frame 27, and the sleeve is pushed to move and fit onto the surface of the sleeve 19. The electric push rod 20 drives the second push arm 21 to move, which in turn drives the moving block 22 to move. The moving block 22 drives the linkage block 23 to rotate, which in turn drives the clamping arm 24 to rotate around the hinge shaft 25. This causes the three clamping arms 24 to rotate outward synchronously, so that the clamping arms 24 contact the inner wall of the sleeve and clamp and fix the sleeve, thereby completing the placement of the sleeve. The casing is protected by a box 1, which also clamps and secures it to prevent displacement due to external forces. Since the casing is a used casing with dirt on its outer surface, the hydraulic rod 11 drives the first push arm 12 downwards. The first push arm 12 then drives the integrated frame 10, slide rod 9, return frame 13, water spray frame 14, and air spray frame 15 downwards, bringing the water spray frame 14 and air spray frame 15 close to the surface of the casing body 8. Then, the high-pressure water pump inside the water tank 3 is turned on, pumping the cleaning fluid from the water tank 3 through the first flexible hose 5. The cleaning fluid is pressed into the water spray frame 14 and sprayed out through the water spray frame 14 to form a high-pressure water jet. The high-pressure water jet washes away the dirt on the surface of the casing body 8. At the same time, the second servo motor 26 drives the sleeve 19 to rotate, and the sleeve 19 drives the casing body 8 to rotate, so that other parts of the casing body 8 are rotated to the position of the water jet, thereby thoroughly cleaning the surface of the casing body 8. When a part of the surface of the casing body 8 has been cleaned, the first servo motor 18 drives the lead screw 16 to rotate, and the lead screw 16 drives the return frame 1 through the threaded sleeve 17. 3. Movement: The water spray frame 14 and air spray frame 15 are moved laterally above the casing body 8 by the U-shaped frame 13 to move the water spray frame 14 and air spray frame 15 to other parts of the first servo motor 18 for cleaning. The air pump 4 pumps gas into the air spray frame 15 through the second flexible hose 6. The gas is sprayed out through the air spray frame 15 to the cleaned surface of the casing body 8 to dry it. The above operation is repeated to complete the cleaning and drying of the entire casing body 8. The mud and sewage washed off are discharged through the drain port at the bottom of the placement box 1.
