Description

Technical Field

[0001] This utility model relates to the field of oil extraction technology, and in particular to a pipe clamping device for oil drilling pipes. Background Technology

[0002] Alloy drilling pipes are generally irregularly shaped tubes, with thicker walls at the ends and / or middle. The purpose of thickening the walls at the ends is to maintain sufficient strength after machining the connecting threads. The purpose of thickening the walls in the middle is to increase the radius of gyration of the drilling pipe section, relatively reducing its slenderness ratio and improving its stiffness and strength. Because both the inner and outer diameters of the drilling pipe change, it cannot be straightened using roller straightening methods, nor is it convenient for tensile or compressive straightening.

[0003] The existing patent technology CN202140030U aluminum alloy drilling pipe describes a drilling pipe comprising multiple sections of variable inner diameter pipe, which are integrally formed. The inner diameter of the first section gradually increases from the open end to the connection end between the first and second sections. The inner diameter of the second section is equal to the inner diameter at the connection end between the first and second sections. The inner diameter of the third section gradually decreases from the connection point between the second and third sections to the center of the third section, and then gradually increases from the center of the third section to the connection point between the third and fourth sections. The diameter of the fourth section is equal to the inner diameter at the connection point between the third and fourth sections. The inner diameter of the fifth section gradually decreases from the connection point between the fourth and fifth sections to the open end. ， It facilitates tensile or compressive straightening.

[0004] The existing connection between the two drilling pipes is a threaded connection, which cannot guarantee that the deep-sea oil drilling pipes will remain sealed and stable after long-term use. As a result, some oil will leak out through the gap between the two drilling pipes during the extraction process, thus polluting the marine ecological environment. Utility Model Content

[0005] The purpose of this utility model is to provide a pipe clamping device for oil drilling pipes, which solves the problem that after long-term use, two drilling pipes cannot maintain a seal and stability, resulting in some oil leaking out through the gap between the two drilling pipes during the extraction process, thus polluting the marine ecological environment.

[0006] To achieve the above objectives, this utility model provides a pipe clamping device for oil drilling pipes, including a pipe and a pipe clamping assembly. The pipe clamping assembly includes a first clamping plate, a second clamping plate, a connecting member, a threaded rod, and a sealing member. The first clamping plate is slidably connected to the pipe and located on the outside of the pipe. The second clamping plate is slidably connected to the pipe and located on the side of the pipe away from the first clamping plate, and abuts against the first clamping plate. The threaded rod is connected to the first clamping plate and the second clamping plate through the connecting member, which supports the threaded rod. The sealing member is installed on the first clamping plate and improves the sealing performance.

[0007] The sealing component includes a sealing ring and a sealing strip. The sealing ring is fixedly connected to the first card plate and is located on the side of the first card plate near the second card plate, and abuts against the second card plate. The sealing strip is fixedly connected to the first card plate and is located on the side of the first card plate near the second card plate, and is connected to the second card plate.

[0008] The second card plate has a sealing ring located on the side of the second card plate near the sealing ring and engaging with the sealing ring; the second card plate also has a sealing groove located on the side of the second card plate near the sealing strip and engaging with the sealing strip.

[0009] The connecting component includes a first connecting block, a second connecting block, and a guide element. The first connecting block is fixedly connected to the first clamping plate and is located on the side of the first clamping plate away from the second clamping plate, and is connected to the threaded rod. The second connecting block is fixedly connected to the second clamping plate and is located on the side of the second clamping plate away from the first clamping plate, and is connected to the threaded rod. The guide element is installed on the first connecting block and supports the second clamping plate.

[0010] The guiding element includes a mounting base and a guide rod. The mounting base is fixedly connected to the first connecting block and is located on the side of the first connecting block closer to the second card plate. The guide rod is fixedly connected to the mounting base and is located on the side of the mounting base away from the first connecting block, and is connected to the second connecting block.

[0011] This utility model discloses a pipe clamping device for oil drilling pipes. A first clamping plate is slidably installed at the connection point of two pipes, and a second clamping plate is slidably installed at the connection point of two pipes. A threaded rod connects the first and second clamping plates via a connecting member. When the threaded rod rotates, it drives the first and second clamping plates to move relative to each other, thereby ensuring tight contact between the first and second clamping plates and the pipes. A sealing member is installed on the first clamping plate, which improves the sealing degree between the first and second clamping plates and the pipes. This ensures that oil will not leak in the event of a pipe rupture, thus achieving the effect of maintaining stability between the two drilling pipes without slippage or oil leakage.

[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0018] The first embodiment of this application is as follows:

[0019] Please see Figures 1 to 3 , Figure 1 This is a schematic diagram of the overall structure of a pipe clamping device for an oil drilling pipe according to the first embodiment of this utility model. Figure 2 This is a front view of a pipe clamping device for an oil drilling pipe according to the first embodiment of this utility model. Figure 3This is a schematic diagram of the structure of the second card plate in the first embodiment of this utility model.

[0020] This utility model provides a pipe clamping device for oil drilling pipes, including a pipe 100 and a pipe clamping assembly. The pipe clamping assembly includes a first clamping plate 101, a second clamping plate 102, a connecting member, a threaded rod 103, and a sealing member. The sealing member includes a sealing ring 104 and a sealing strip 105. The second clamping plate 102 has a sealing ring 106 and a sealing groove 107. The connecting member includes a first connecting block 108, a second connecting block 109, and a guiding element. The guiding element includes a mounting base 110 and a guide rod 111. This solution solves the problem that after prolonged use, two drilling pipes cannot maintain a seal and stability, causing some oil to leak out through the gap between the two drilling pipes during extraction, thus polluting the marine ecological environment.

[0021] In this specific embodiment, the pipeline 100 is the drilling pipe described in the patented technology CN202140030U aluminum alloy drilling pipe. Oil is extracted through the pipeline 100. This solution achieves the effect of maintaining stability between the two drilling pipes without slippage or oil leakage.

[0022] The first clamping plate 101 is slidably connected to the pipe 100 and located outside the pipe 100. The second clamping plate 102 is slidably connected to the pipe 100 and located on the side of the pipe 100 away from the first clamping plate 101, and abuts against the first clamping plate 101. The threaded rod 103 is connected to the first clamping plate 101 and the second clamping plate 102 through the connecting member, which supports the threaded rod 103. The sealing member is installed on the first clamping plate 101 to improve sealing. The first clamping plate 101 is slidably installed at the connection point of the two pipes 100, and the second clamping plate 102 is slidably installed at the connection point of the two pipes 100. The threaded rod 103 is connected through the connecting member. Connecting the first clamping plate 101 and the second clamping plate 102, the threaded rod 103 drives the first clamping plate 101 and the second clamping plate 102 to move relative to each other when rotating, thereby making the first clamping plate 101 and the second clamping plate 102 tightly abut against the pipe 100. The threaded rod 103 is made of SUS316 stainless steel, which allows it to be used in seawater for a long time. The sealing member is installed on the first clamping plate 101. The sealing member improves the sealing degree between the first clamping plate 101, the second clamping plate 102 and the pipe 100, so that when the pipe 100 ruptures, oil will not leak. This achieves the effect of maintaining stability between the two drilling pipes without slippage or oil leakage.

[0023] Secondly, the sealing ring 104 is fixedly connected to the first card plate 101 and located on the side of the first card plate 101 near the second card plate 102, and abuts against the second card plate 102; the sealing strip 105 is fixedly connected to the first card plate 101 and located on the side of the first card plate 101 near the second card plate 102, and connected to the second card plate 102. The sealing ring 104 is glued to the side of the first card plate 101 near the second card plate 102, so that after the threaded rod 103 drives the first card plate 101 and the second card plate 102 to move, the sealing ring 104 can engage with the first card plate 101. The sealing strip 105 is installed on the first card plate 101 with glue and abuts against the second card plate 102. The cooperation of the sealing ring 104 and the sealing strip 105 improves the sealing performance between the first card plate 101 and the second card plate 102.

[0024] Meanwhile, the second card plate 102 has a sealing ring 106, which is located on the side of the second card plate 102 near the sealing ring 104 and cooperates with the sealing ring 104; the second card plate 102 has a sealing groove 107, which is located on the side of the second card plate 102 near the sealing strip 105 and cooperates with the sealing strip 105. The sealing ring 106 is located on the side of the second card plate 102 near the sealing ring 104, which makes the sealing ring 104 more tightly connected to the second card plate 102. The sealing groove 107 is located on the side of the second card plate 102 near the sealing strip 105, which improves the sealing degree between the second card plate 102 and the first card plate 101 through the cooperation of the sealing groove 107 and the sealing strip 105.

[0025] Additionally, the first connecting block 108 is fixedly connected to the first clamping plate 101 and located on the side of the first clamping plate 101 away from the second clamping plate 102, and is connected to the threaded rod 103; the second connecting block 109 is fixedly connected to the second clamping plate 102 and located on the side of the second clamping plate 102 away from the first clamping plate 101, and is connected to the threaded rod 103; the guide element is mounted on the first connecting block 108, the guide element supports the second clamping plate 102, the first connecting block 108 is bolted to the side of the first clamping plate 101 away from the pipe 100, and the second connecting block 109 is bolted to the side of the second clamping plate 102 away from the pipe 100. On one side of the pipe 100, the threaded rod 103 is mounted on the first connecting block 108 via a bearing, allowing the threaded rod 103 to rotate on the first connecting block 108 and pass through the second connecting block 109. The second connecting block 109 has a threaded hole that mates with the threaded rod 103, so that the threaded rod 103 can drive the second connecting block 109 to move when rotating, thereby driving the second clamping plate 102 to move toward one side of the first clamping plate 101, thereby clamping the pipe 100. The guide element is mounted on the first connecting block 108, and the guide element enables the second connecting block 109 to move more stably, improving the stability of the equipment.

[0026] Finally, the mounting base 110 is fixedly connected to the first connecting block 108 and is located on the side of the first connecting block 108 near the second clamping plate 102; the guide rod 111 is fixedly connected to the mounting base 110 and is located on the side of the mounting base 110 away from the first connecting block 108, and is connected to the second connecting block 109. The mounting base 110 is bolted to the side of the first connecting block 108 near the second clamping plate 102. The guide rod 111 is welded to the mounting base 110. The mounting base 110 makes the guide rod 111 more stably mounted on the first connecting block 108. The guide rod 111 passes through the second connecting block 109. The guide rod 111 makes the second connecting block 109 move more stably, thereby improving the stability of the second connecting block 109 when it moves.

[0027] Using a pipe clamping device for an oil drilling pipe according to this embodiment, after the pipe 100 is installed, the first clamping plate 101 and the second clamping plate 102 are placed at the connection of the pipe 100, and the second connecting block 109 passes through the guide rod 111, so that the second connecting block 109 abuts against the threaded rod 103. At this time, the threaded rod 103 is rotated, so that the second connecting block 109 drives the second clamping plate 102 to move, thereby clamping the pipe 100 with the second clamping plate 102 and the first clamping plate 101, and making the sealing ring 104 and the sealing strip 105 engage with the sealing ring 106 and the sealing groove 107 respectively, thereby achieving the effect of maintaining stability between the two drilling pipes without slippage or oil leakage.

[0028] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that implementing all or part of the above embodiments and making equivalent changes in accordance with the claims of this application still fall within the scope of this application.
