[0002] With the development of technology, tubing systems are used for transporting media such as hydraulic oil pipes in engineering machinery, offshore natural gas, petroleum, irrigation, steel mills, and chemical plants. Tubing sleeve clamping tools, as part of these systems, are used to clamp external tubing. In existing technology, current tubing sleeve clamping tools consist of a tube body and a clamping block. The tube body passes through an external tubing, which has a clamping groove. The clamping block is fixedly connected to the tube body and engages with the external tubing's clamping groove as the tube body moves. However, the clamping block only deforms to achieve clamping, making it prone to damage and resulting in poor clamping convenience for existing tubing sleeve clamping tools. Summary of the Invention

[0046] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0047] Please refer to the attached document. Figures 1-5 This application provides a tubing sleeve engaging tool 100, which is applied to a tubing device and is used to engage an external tubing.

[0048] Please refer to the attached document. Figures 1-5In this embodiment, the tubing sleeve engaging tool 100 includes a hanging member 10, a pipe body 20, an engaging member 30, a limiting member 40, and a first elastic member 50. The hanging member 10 is used for hanging by external hanging equipment. The pipe body 20 has an inner cavity 20a and at least one diversion hole 20b, with the inner cavity 20a extending along the length of the pipe body 20. The diversion hole 20b is opened on the peripheral sidewall of the pipe body 20 and communicates with the inner cavity 20a. The engaging member 30 is telescopically connected to the pipe body 20 and elastically telescopic relative to the pipe body 20. The engaging member 30 can engage an external tubing in the extended state. The limiting member 40 is movably connected to the pipe body 20 and is disposed on one side of the engaging member 30. The diversion hole 20b communicates with the groove 40a of the limiting member 40. The first elastic member 50 is sleeved on the pipe body 20. On the outside of 0, an elastic force is applied to the limiting member 40; when liquid is injected into the inner cavity 20a, the liquid enters the groove 40a of the limiting member 40 from the inner cavity 20a, and drives the limiting member 40 to move relative to the tube body 20, and gradually compresses the first elastic member 50 and moves away from the locking member 30, so that the locking member 30 gradually extends relative to the tube body 20; when the liquid injection stops, the first elastic member 50 applies an elastic force to the locking member 30, and the limiting member 40 gradually moves toward the locking member 30, so that the locking member 30 gradually retracts relative to the tube body 20. The movement of the limiting member 40 is adjusted based on the liquid injection, thereby realizing the control of the extension and retraction of the locking member 30, avoiding the limiting member 40 from simply deforming and locking, and improving the locking convenience of the oil pipe sliding sleeve locking tool 100.

[0049] Please refer to the attached document. Figures 1-5 In this embodiment of the application, the hanging member 10 is used for external hanging equipment to hang the oil pipe sliding sleeve clamping tool 100 through the hanging member 10.

[0050] The tube body 20 is provided with an inner cavity 20a and at least one diversion hole 20b. The inner cavity 20a serves as the internal space of the tube body 20 and extends along the length of the tube body 20. The diversion hole 20b is opened on the peripheral sidewall of the tube body 20 and communicates with the inner cavity 20a.

[0051] The engaging member 30 is disposed on the outer side wall of the pipe body 20. The engaging member 30 is telescopically connected to the pipe body 20 and elastically expands and contracts relative to the pipe body 20. When extended, the engaging member 30 can engage with the external oil pipe so that the pipe body 20 can be engaged with the external oil pipe through the engaging member 30.

[0052] The limiting member 40 is movably connected to the tube body 20 and is disposed on one side of the engaging member 30 to facilitate adjustment of the position of the limiting member 40 relative to the tube body 20; the diversion hole 20b communicates with the groove 40a of the limiting member 40 so that the inner cavity 20a can be connected to the groove 40a of the limiting member 40 through the diversion hole 20b.

[0053] The first elastic element 50 is sleeved on the outside of the pipe body 20 and applies an elastic force to the limiting element 40; so that the limiting element 40 can be reset without external force, thus facilitating the limiting element 40 to be in the initial position. This ensures that the oil pipe sleeve engaging tool 100 is always in the retracted state when it does not need to be activated, thereby ensuring that the oil pipe sleeve engaging tool 100 will not be accidentally activated during the insertion process. When liquid is injected into the inner cavity 20a, the liquid enters the groove 40a of the limiting member 40 from the inner cavity 20a, causing the limiting member 40 to move relative to the pipe body 20, and gradually compressing the first elastic member 50 and moving away from the engaging member 30, so that the engaging member 30 gradually extends relative to the pipe body 20; when the liquid injection stops, the first elastic member 50 applies an elastic force to the engaging member 30, and the limiting member 40 gradually moves towards the engaging member 30, so that the engaging member 30 gradually retracts relative to the pipe body 20. The movement of the limiting member 40 is adjusted based on the liquid injection, thereby realizing the control of the extension and retraction of the engaging member 30, avoiding the limiting member 40 merely deforming to engage, and improving the engaging convenience of the oil pipe sliding sleeve engaging tool 100. Optionally, the first elastic member 50 is a spring.

[0054] The tube body 20 is connected to an activation shear pin, which is close to the diversion hole 20b. This ensures that a higher hydraulic pressure is required to shear the activation shear pin during initial use, and then the compression limit member 40 gradually compresses the first elastic member 50 and moves away from the locking member 30, so that the locking member 30 gradually extends out relative to the tube body 20.

[0055] Please refer to the attached document. Figures 1-2 In this embodiment, the hanging member 10 is disposed at the end of the pipe body 20. The peripheral sidewall of the hanging member 10 is provided with a hanging part 11, which is used for external hanging equipment to hang on it. This facilitates the connection between the external hanging equipment and the hanging part 11, thereby enabling the external hanging equipment to hang the hanging member 10 through the hanging part 11. The hanging member 10 is provided with a through hole 10a, which communicates with the inner cavity 20a, so that liquid can enter the inner cavity 20a through the through hole 10a, ensuring the liquid output position.

[0056] Please refer to the attached document. Figures 1-2In this embodiment, the tubing sleeve engaging tool 100 further includes a first connecting seat 60, which is disposed on the peripheral sidewall of the tubing body 20 and connected to the hanging member 10. The first connecting seat 60 is stationary relative to the tubing body 20, ensuring the position of the first connecting seat 60 relative to the tubing body 20 and preventing positional displacement of the first connecting seat 60. A first elastic member 50 is disposed between the first connecting seat 60 and the limiting member 40. The two ends of the first elastic member 50 elastically contact the first connecting seat 60 and the limiting member 40 respectively, so that the end of the first elastic member 50 disposed relative to the first connecting seat 60 is in a stationary state. When the liquid is adjusted from the injection state to the stop state, the first elastic member 50 applies an elastic force to the limiting member 40 and moves toward the engaging member 30, thereby facilitating the gradual retraction of the engaging member 30 relative to the tubing body 20.

[0057] Please refer to the attached document. Figures 1-5 In this embodiment of the application, the limiting member 40 is provided with a second connecting seat 41, which is arranged opposite to the first connecting seat 60 and clamps a first elastic member 50, so that the limiting member 40 can clamp the first elastic member 50 with the first connecting seat 60 through the second connecting seat 41, thereby facilitating the first elastic member 50 to apply an elastic force to the limiting member 40 through the second connecting seat 41.

[0058] Please refer to the attached document. Figures 1-5 In this embodiment, the engaging member 30 includes an engaging body 31 and an engaging portion 32, with the engaging portion 32 connected to the engaging body 31. The engaging body 31 is connected to the tube body 20, allowing the engaging member 30 to connect to the tube body 20 via the engaging body 31. The limiting member 40 includes a limiting body 42 and a limiting arm 43. The inner contour of the limiting body 42 is clearance-fitted with the outer contour of the tube body 20. The limiting body 42 is movably connected to the tube body 20 to adjust the position of the limiting body 42 relative to the tube body 20, thereby facilitating the movement of the limiting member 40 relative to the tube body 20 via the limiting body 42. A limiting arm 43 is connected to the side wall of the limiting body 42 facing the engaging member 30 and extends outward; a groove 40a is formed between the limiting arm 43 and the limiting body 42; the limiting arm 43 is sleeved on the outside of the engaging part 32, and the limiting arm 43 moves closer to or away from the engaging part 32 as the limiting body 42 moves, so as to release or restrict the engaging body 31. When liquid enters the groove 40a, it pushes the limiting body 42, thereby facilitating the limiting arm 43 to move away from the engaging part 32, releasing the engaging body 31, and thus facilitating the engaging member 30 to engage the external oil pipe in the extended state.

[0059] Please refer to the attached document. Figures 1-5In this embodiment, the limiting body 42 is connected to a third connecting seat 421, which is located within the groove 40a and is sealed to the pipe body 20 and the limiting arm 43. This ensures the sealing effect of the third connecting seat 421 relative to the pipe body 20 and the limiting arm 43, preventing liquid from flowing to the engaging member 30. Liquid entering through the diversion hole 20b remains within the groove 40a and exerts a force on the third connecting seat 421 and the limiting body 42, causing the limiting member 40 to move away from the engaging member 30. This allows the limiting member 40 to release the engaging member 30, which remains relatively stationary relative to the pipe body 20 and is fixedly connected to it. This facilitates the engaging member 30 engaging external oil pipes in its extended state. Optionally, the third connecting seat 421 can be sealed to the pipe body 20 and the limiting arm 43 using multiple sealing rings.

[0060] Please refer to the attached document. Figures 1-5 In this embodiment, the end of the limiting arm 43 furthest from the limiting body 42 is provided with a first beveled end 431; the corner of the engaging body 31 is provided with a second beveled end 311; the second beveled end 311 can cooperate with the first beveled end 431. When the limiting arm 43 approaches the engaging body 31, the first beveled end 431 and the second beveled end 311 can play a guiding role. The first beveled end 431 and the second beveled end 311 will have a relative sliding process when they come into contact, so that the limiting arm 43 can make contact with the engaging body 31 more smoothly and enter the predetermined position, instead of a direct hard collision, thereby reducing the impact force and wear when the limiting arm 43 comes into contact with the engaging body 31.

[0061] Please refer to the attached document. Figures 1-4 In this embodiment, the tubing sliding sleeve engaging tool 100 further includes a second elastic element 70, which is located between the tubing body 20 and the engaging body 31. Multiple second elastic elements 70 are arranged along the length of the engaging body 31 and are positioned and connected to it. This ensures the positional accuracy of the multiple second elastic elements 70 relative to the engaging body 31. The multiple second elastic elements 70 apply an elastic force to the engaging portion 32, so that the engaging portion 32 is compressed relative to the tubing body 20. The engaging portion 32 can be inserted into the engaging groove of an external tubing, so that the engaging portion 32 engages with the external tubing. Optionally, the second elastic element 70 is a spring.

[0062] Please refer to the attached document. Figures 1-2In this embodiment, two limiting members 40 are provided, which are arranged on both sides of the engaging member 30. Two diversion holes 20b are provided, which are arranged relative to the corresponding limiting members 40, so that the two limiting members 40 move away from or move closer to the engaging member 30 simultaneously under the action of the liquid, so as to restrict or move away from the two ends of the engaging member 30 by the two limiting members 40, thus ensuring the engaging effect of the engaging member 30 relative to the external oil pipe.

[0063] In this embodiment of the application, an oil pipe device includes an oil pipe sliding sleeve clamping tool 100, which is part of the oil pipe device. The oil pipe device is used for conveying media such as hydraulic oil pipes for engineering machinery, submarine natural gas, petroleum, irrigation, steel plants, and chemical plants.

[0064] The tubing assembly also includes an activator, which is detachably connected to the tubing sleeve engaging tool 100, improving the ease of replacement of the activator. The activator has a central hole, and the flow area of ​​the central hole can be changed on-site according to the well inclination angle, fluid viscosity and activation pressure requirements to increase or decrease the fluid pressure required by the activator.

[0065] Compared with the prior art, the beneficial effects of the present invention are:

The diversion hole 20b is formed on the peripheral sidewall of the tubing body 20 and communicates with the inner cavity 20a. An engaging member 30 is telescopically connected to the tubing body 20 and elastically expands and contracts relative to the tubing body 20. In its extended state, the engaging member 30 can engage an external tubing. A limiting member 40 is movably connected to the tubing body 20 and is disposed on one side of the engaging member 30. The diversion hole 20b communicates with the groove 40a of the limiting member 40. A first elastic member 50 is sleeved on the outer side of the tubing body 20 and applies elastic force to the limiting member 40. The liquid acts as an elastic force; when the liquid is injected into the inner cavity 20a, the liquid enters the groove 40a of the limiting member 40 from the inner cavity 20a, and drives the limiting member 40 to move relative to the pipe body 20, and gradually compresses the first elastic member 50 and moves away from the locking member 30, so that the locking member 30 gradually extends relative to the pipe body 20; when the liquid injection stops, the first elastic member 50 applies an elastic force to the locking member 30, and the limiting member 40 gradually moves toward the locking member 30, so that the locking member 30 gradually retracts relative to the pipe body 20. The movement of the limiting member 40 is adjusted based on the liquid injection, thereby realizing the control of the extension and retraction of the locking member 30, avoiding the limiting member 40 from simply deforming and locking, and improving the locking convenience of the oil pipe sliding sleeve locking tool 100.
