Description

Technical Field

[0001] This utility model relates to the technical field of oil drill pipe anti-corrosion equipment, specifically a sealing device for processing anti-corrosion coatings on oil drill pipes. Background Technology

[0002] Oil drill pipe is a primary tool used in oil and gas drilling and geological exploration. It is made of seamless steel pipe and its main functions are to connect the surface drilling rig and the drill bit and other equipment located at the bottom of the well, to transmit power, transport drilling fluid and mud, and to lift, lower or rotate the drilling equipment at the bottom.

[0003] Furthermore, oil drill pipes come into contact with hydrogen-containing oil and gas environments during oilfield operations. Steel undergoes hydrogenation in hydrogen-containing environments, leading to embrittlement, damage to mechanical properties, and impact on oil and gas extraction. Therefore, appropriate anti-corrosion measures are required. A common method is to apply anti-corrosion spraying to the surface. However, the harmful gases produced during anti-corrosion spraying can affect operators. Therefore, a sealing device for processing anti-corrosion coatings on oil drill pipes needs to be designed.

[0006] The spraying and sealing mechanism includes an electro-hydraulic rod, which is fixedly connected to the top of the base. A plate is fixedly connected to the top of the electro-hydraulic rod. Electric push rods are fixedly connected to the four sides inside the plate. A sealing frame is fixedly connected to the bottom of the electric push rod. A telescopic cover is fixedly connected to the top of the sealing frame. The top of the telescopic cover is fixedly connected to the bottom of the plate.

[0007] Preferably, the flat plate has a circular hole inside, and the telescopic tube has a circular hole extending through the flat plate. The bottom end of the telescopic tube is connected to the inside of the spray head, which facilitates the telescopic tube to spray the anti-corrosion coating using the spray head.

[0008] Preferably, the clamping mechanism includes a base plate, which is fixedly connected to the top center of the base. A T-shaped ring is rotatably connected to the top of the base plate, and a positioning ring is fixedly connected to the top of the T-shaped ring. T-shaped blocks are slidably connected to the interior of the four ends of the base plate. A T-shaped tip is rotatably connected to the top of each T-shaped block, and a connecting strip is rotatably connected to the surface of the T-shaped tip. An ear plate seat is rotatably connected to one end of the connecting strip. A first spring is fixedly connected to one end of the T-shaped block, and one end of the first spring is fixedly connected to the interior of the base plate. A connecting plate is fixedly connected to one side of the T-shaped block, and an arc-shaped clamping plate is fixedly connected to one end of the connecting plate. An L-shaped frame is fixedly connected to the top of the base plate, and a second spring is fixedly connected to the top of the L-shaped frame. A T-shaped rod is fixedly connected to the top of the second spring. A through hole is opened at the top of the L-shaped frame, and the surface of the T-shaped rod passes through the through hole at the top of the L-shaped frame. The interior of the T-shaped ring is fixedly connected to the surface of the ear plate seat.

[0009] Preferably, a positioning hole is formed on the surface of the positioning ring, and the lower surface of the T-shaped rod matches the inside of the positioning hole, so that the positioning ring can be easily inserted into the positioning hole.

[0010] Preferably, a guide groove is formed inside the base plate, and the surface of the T-shaped block is slidably connected to the inside of the guide groove.

[0011] Preferably, the bottom plate has a groove on its side, and the surface of the connecting plate is located inside the groove.

[0012] Preferably, a sealing groove is provided on the top of the base plate, and the lower surface of the sealing frame is in close contact with the inside of the sealing groove, so that the connecting plate can perform a sealing function inside the sealing groove.

[0013] Compared with the prior art, this utility model provides a sealing device for processing anti-corrosion coatings on oil drill pipes, which has the following beneficial effects:

[0014] 1. This sealing equipment for processing anti-corrosion coatings on oil drill pipes utilizes a spray sealing mechanism. A cylinder drives an L-shaped plate to reciprocate vertically, achieving a spray coating effect on the workpiece. Furthermore, since toxic gases are generated during spraying, before spraying, an electric actuator moves the sealing frame downwards, causing the telescopic cover to extend and engage with the base plate. This ensures a sealed environment for the workpiece spraying, effectively preventing gas diffusion during oil drill pipe spraying and guaranteeing operator safety.

[0015] 2. This sealing equipment for processing anti-corrosion coatings on oil drill pipes, through a clamping mechanism, rotates the positioning ring, causing the T-shaped ring to rotate, which in turn causes the ear plate seat to rotate. This, in turn, causes the connecting strip to move, causing the T-shaped block to slide inside the base plate. As a result, when the connecting plate moves, the arc-shaped clamping plate clamps and fixes the oil drill pipe workpiece, thus ensuring stable support for the drill pipe during spraying.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] This utility model provides the following technical solution: Example

[0028] Combination Figures 2 to 7 A sealing device for processing anti-corrosion coatings on oil drill pipes includes a base 1, a spraying sealing mechanism 2 fixedly connected to the four ends of the top of the base 1, and a clamping mechanism 3 fixedly connected to the middle of the top of the base 1.

[0029] The spray sealing mechanism 2 includes an electric hydraulic rod 21, which is fixedly connected to the top of the base 1. A plate 22 is fixedly connected to the top of the electric hydraulic rod 21. An electric push rod 23 is fixedly connected to the four sides inside the plate 22. A sealing frame 25 is fixedly connected to the bottom of the electric push rod 23. A telescopic cover 24 is fixedly connected to the top of the sealing frame 25. The top of the telescopic cover 24 is fixedly connected to the bottom of the plate 22. A cylinder 26 is fixedly connected to the other four sides inside the plate 22. An L-shaped plate 27 is fixedly connected to the bottom of the cylinder 26. A spray nozzle 28 is fixedly connected to the inside of the L-shaped plate 27. A telescopic tube 29 is fixedly connected to the top of the spray nozzle 28.

[0030] Furthermore, a circular hole is opened inside the flat plate 22, and a circular hole is opened inside the surface of the telescopic tube 29 through the flat plate 22. The bottom end of the telescopic tube 29 is connected to the inside of the nozzle 28. The cylinder 26 drives the L-shaped plate 27 to reciprocate in the vertical direction, thereby achieving the spraying effect on the workpiece. In addition, toxic gases are generated during spraying. Therefore, before spraying, when the electric actuator 23 drives the sealing frame 25 to move downward, it drives the telescopic cover 24 to extend, thereby driving the sealing frame 25 to lock into the bottom plate 31, thereby achieving the airtightness of the workpiece spraying environment. This can effectively prevent the diffusion of gas when spraying oil drill pipes, thus ensuring the safety of the operator. Example

[0031] See Figure 1-7 Furthermore, based on Embodiment 1, the clamping mechanism 3 further includes a base plate 31, which is fixedly connected to the top center of the base 1. A T-shaped ring 32 is rotatably connected to the top of the base plate 31, and a positioning ring strip 37 is fixedly connected to the top of the T-shaped ring 32. T-shaped blocks 33 are slidably connected to the four ends of the base plate 31, and T-shaped tips 341 are rotatably connected to the top of the T-shaped blocks 33. A connecting strip 34 is rotatably connected to the surface of the T-shaped tips 341, and an ear plate seat 343 is rotatably connected to one end of the connecting strip 34. A first spring 342 is fixedly connected to one end of the T-shaped blocks 33, and one end of the first spring 342 is fixedly connected to the inside of the base plate 31. A connecting plate is fixedly connected to one side of the T-shaped blocks 33. 35. One end of the connecting plate 35 is fixedly connected to an arc-shaped clamping plate 36. The top of the base plate 31 is fixedly connected to an L-shaped frame 38. The top of the L-shaped frame 38 is fixedly connected to a second spring 381. The top of the second spring 381 is fixedly connected to a T-shaped rod 39. The top of the L-shaped frame 38 has a through hole. The surface of the T-shaped rod 39 passes through the through hole at the top of the L-shaped frame 38. The inside of the T-shaped ring 32 is fixedly connected to the surface of the ear plate seat 343. The surface of the positioning ring 37 has a positioning hole. The lower surface of the T-shaped rod 39 matches the inside of the positioning hole. The inside of the base plate 31 has a guide groove. The surface of the T-shaped block 33 is slidably connected to the inside of the guide groove. The side of the base plate 31 has a slot. The surface of the connecting plate 35 is located inside the slot.

[0032] Furthermore, a sealing groove is provided on the top of the base plate 31, and the lower surface of the sealing frame 25 is tightly fitted with the inside of the sealing groove. When the rotating positioning ring 37 drives the T-shaped ring 32 to rotate, it drives the ear plate seat 343 to rotate, which in turn drives the connecting strip 34 to move, causing the T-shaped block 33 to slide inside the base plate 31. This causes the connecting plate 35 to move, which in turn causes the arc-shaped clamping plate 36 to perform clamping and fixing operations on the oil drill pipe workpiece, thereby ensuring stable support for the drill pipe during spraying.

[0033] In actual operation, when this device is used to spray oil drill pipe, it is first clamped. At this time, the T-shaped rod 39 is pulled up and disengaged from the positioning ring 37. Then, the positioning ring 37 is rotated, which drives the T-shaped ring 32 to rotate. This drives the ear plate seat 343 to rotate, which in turn drives the connecting strip 34 to move. This causes the T-shaped block 33 to slide inside the base plate 31, thereby driving the connecting plate 35 to move. This causes the arc-shaped clamping plate 36 to perform clamping and fixing operations on the oil drill pipe workpiece, thus ensuring stable support for the drill pipe during spraying.

[0034] Furthermore, during spraying, the electric hydraulic rod 21 lowers the plate 22 until the nozzle 28 is in the appropriate spraying position. The telescopic tube 29 is connected to the spraying liquid and the workpiece is sprayed using the four nozzles 28. During spraying, the cylinder 26 drives the L-shaped plate 27 to reciprocate in the vertical direction, thereby achieving the spraying effect on the workpiece. In addition, toxic gases are generated during spraying. Therefore, before spraying, when the electric push rod 23 moves the sealing frame 25 downward, it causes the telescopic cover 24 to extend, thereby causing the sealing frame 25 to be locked into the bottom plate 31, thereby achieving the airtightness of the workpiece spraying environment. This effectively prevents the diffusion of gas during oil drill pipe spraying, thus ensuring the safety of the operator.
