[0002] Titanium-steel composite pipe is a type of dissimilar metal composite pipe that combines the high strength, high rigidity, and low cost of carbon steel with the corrosion resistance, high and low temperature resistance, and erosion resistance of titanium. It effectively solves the industry pain points of easy corrosion of single carbon steel pipes and high cost and insufficient strength of pure titanium pipes. It is widely used in harsh working conditions such as petrochemical, marine engineering, power desulfurization, and fine chemical industries.

[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0030] Example 1, referring to Figures 1-7 This is the first embodiment of the present invention, which provides an automated docking device for titanium-steel composite pipes, including: a device frame 1, on both sides of its top of which docking sleeves 11 are slidably connected; a pad 12 is fixedly connected to the bottom of the inner wall of the docking sleeves 11; a positioning plate 13 is rotatably connected to the inner cavity of the docking sleeves 11; a through groove 14 is opened in the inner wall of the docking sleeves 11 and cooperates with the positioning plate 13; a driving member 15 is disposed at the bottom of the docking sleeves 11; a sliding rod 2 is rotatably connected to the bottom of the inner cavity of the docking sleeves 11, with one side of the rod penetrating the docking sleeves 11 and slidably connected to a sliding sleeve 21; the end of the sliding sleeve 21 is fixedly connected to the device frame 1; a clamping member 22 is disposed on the surface of the sliding rod 2 for driving the positioning plate 13 to fix the composite pipe; a cylinder 23 is fixedly connected to the top of one docking sleeve 11, with a docking rod 24 slidably connected to its inner cavity; a docking cylinder 25 is fixedly connected to the top of the other docking sleeve 11; and a trigger member 26 is disposed in the inner cavity of the cylinder 23.

[0031] The equipment frame 1 serves as the overall load-bearing base, providing a stable installation and operating benchmark for all components and ensuring the overall structural stability of the device. The slidingly mounted docking sleeves 11 on both sides of the top of the equipment frame 1 form the core cavity for the load-bearing and docking of the titanium-steel composite pipes, enabling symmetrical alignment of the two sets of pipes and providing structural support for precise pipe docking. The pad 12 fixed to the bottom of the inner wall of the docking sleeve 11 provides stable support for the bottom of the pipes, preventing them from swaying and ensuring basic stability during the docking process. The positioning plate 13, rotatably connected to the inner cavity of the docking sleeve 11, in conjunction with the through groove 14 on the inner wall, allows for multi-angle rotation and clamping, providing structural conditions for adaptive positioning of pipes with different outer diameters. The driving component 15 at the bottom of the docking sleeve 11 serves as the power source for docking displacement, driving the two sets of docking sleeves 11 to move automatically towards each other, replacing the traditional manual pushing alignment method and significantly reducing the intensity of manual operation.

[0032] Meanwhile, the sliding rod 2, which is rotatably connected to the bottom of the inner cavity of the docking sleeve 11, forms a sliding-rotation linkage structure with the sliding sleeve 21 fixed to the equipment frame 1. Relying on the clamping part 22 on the surface of the sliding rod 2, the positioning plate 13 can be automatically driven to complete the pipe clamping and positioning by relying on the mechanical linkage during the docking displacement process. There is no need for manual locking of the clamps, which completely changes the traditional manual fixing operation mode. The cylinder 23 and docking rod 24 at the top of the docking sleeve 11 on one side cooperate with the docking cylinder 25 on the other side. With the trigger part 26 in the inner cavity of the cylinder 23, the automatic unlocking and reset function can be realized after docking is in place, which can effectively avoid docking errors caused by long-term deformation of the equipment and ensure docking accuracy in batch processing.

[0033] Example 2, refer to Figures 1-7 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0034] Specifically, the drive component 15 includes a motor 151 fixedly connected to the bottom of the inner cavity of the equipment frame 1. The output shaft of the motor 151 is fixedly connected to a lead screw 152. A movable block 153 is threadedly connected to the surface of the lead screw 152. Movable rods 154 are hinged to both sides of the movable block 153. The corresponding side of the movable rods 154 is hinged to the docking sleeve 11.

[0035] The motor 151, fixed at the bottom of the inner cavity of the equipment frame 1, serves as the core power output, providing stable and controllable rotational power to support automatic pipeline docking. The lead screw 152, fixedly connected to the output shaft of the motor 151, converts rotational motion into linear reciprocating motion, achieving precise power conversion and ensuring smooth displacement adjustment. The movable block 153, threaded onto the surface of the lead screw 152, rotates with the lead screw 152 to achieve precise linear displacement, preventing excessive displacement deviation from affecting docking accuracy. The movable rods 154 hinged on both sides of the movable block 153 form a bidirectional hinged transmission structure, synchronously converting the linear displacement of the movable block 153 into the opposing sliding displacement of the two sets of docking sleeves 11, achieving synchronous alignment and approach of the pipelines on both sides.

[0036] Specifically, the clamping member 22 includes a drive block 221 fixedly connected to the top of the slide bar 2, and the surface of the slide sleeve 21 is provided with a drive groove 222, which cooperates with the drive block 221.

[0037] A drive block 221 is fixedly installed at the top of the slide rod 2, and a drive groove 222 matching the drive block 221 is opened on the surface of the sliding sleeve 21. Utilizing the change in the relative position of the slide rod 2 and the sliding sleeve 21 during the sliding of the connecting sleeve 11, the drive block 221 slides along the inner wall of the drive groove 222. During the process of the connecting sleeves 11 moving towards each other to complete the pipe connection, the groove trajectory of the drive groove 222 can form a squeezing guide on the drive block 221, thereby driving the slide rod 2 to rotate. No additional drive equipment is needed; the mechanical movement of the connection displacement automatically triggers the clamping and positioning action.

[0038] Specifically, a gear 223 is fixedly connected to the surface of the slide rod 2, a gear 224 meshes with the top of the gear 223, a toothed disc 225 is fixedly connected to the surface of the gear 224, a toothed disc 226 meshes with the corresponding side of the toothed disc 225, a gear 3 227 is provided on the corresponding side of the toothed disc 226, a gear ring 228 meshes with the top of the gear 3 227, a gear 4 229 meshes with the surface of the gear ring 228, a fixing rod 2210 is fixedly connected to the inner cavity of the gear 4 229, and is fixedly connected to the positioning plate 13. The gear ring 228 and the fixing rod 2210 are both rotatably connected to the inner cavity of the docking sleeve 11.

[0039] By fixing gear 223 to the surface of slide rod 2, the rotational power of slide rod 2 is output synchronously. Gear 224, which meshes with the top of gear 223, enables primary power transmission. Gear 225 and gear 226, which are linked by gear 224, form a disengageable transmission structure, providing a structural basis for adaptive adjustment. Gear 227, which is linked by gear 226, enables secondary power transmission. Then, through multi-stage meshing transmission of gear ring 228 and gear 229, the power is transmitted to fixed rod 2210, ultimately driving the positioning plate 13 connected to fixed rod 2210 to rotate. Gear ring 228 and fixed rod 2210 can rotate stably within the cavity of docking sleeve 11, ensuring the smoothness of the transmission process.

[0040] Specifically, a reset rod 2211 is slidably connected to one side of the dental insert 226 and fixedly connected to the gear 3 227. A spring 1 2212 is sleeved on the surface of the reset rod 2211. One side of the spring 1 2212 is fixedly connected to the dental insert 226, and the other side of the spring 1 2212 is fixedly connected to the gear 3 227.

[0041] A reset rod 2211, which is slidably connected to a gear 3 227 and slidably fixed to one side of the second jaw insert 226, is also fitted with a spring 2212. The two ends of the spring 2212 are connected to the second jaw insert 226 and the gear 3 227, respectively. When the positioning plate 13 rotates to fit against the outer wall of the pipe, the pipe creates a reverse limiting resistance against the positioning plate 13. At this time, the first jaw insert 225 continues to rotate to fit against the second jaw insert 226, which pushes the second jaw insert 226 to slide along the reset rod 2211 and compress the spring 2212, achieving automatic disengagement of the jaw insert structure and preventing continuous pressure from rigid transmission that could cause pipe deformation or equipment damage. After the pipe processing is completed and the resistance is removed, the elastic reset force of the spring 2212 can push the second jaw insert 226 back to its original position, restoring the transmission engagement state.

[0042] Specifically, a limiting plate 2213 is rotatably connected to one side of gear 224 and gear 3 227, and the top of the limiting plate 2213 is fixedly connected to the inner cavity of the docking sleeve 11.

[0043] The top of the limiting plate 2213 is fixed to the inner cavity of the docking sleeve 11, and at the same time, the rotation limit support of gear 224 and gear 327 is provided. This can effectively limit the radial displacement and axial sway of gear 224 and gear 327, and avoid problems such as gear meshing deviation, transmission jamming, and power loss caused by equipment vibration or long-term wear.

[0044] Specifically, the trigger element 26 includes a second spring 261 fixedly connected to the inner cavity of the cylinder 23. One side of the second spring 261 is fixedly connected to the docking rod 24. The top of the docking rod 24 is provided with an embedding groove 262. A locking block 263 is slidably connected to the inner cavity of the embedding groove 262. The top of the cylinder 23 is provided with a locking groove 264, which communicates with the inner cavity of the docking rod 24. The bottom of the locking block 263 is fixedly connected with a third spring 265, which is fixedly connected to the inner cavity of the locking groove 264.

[0045] The connecting rod 24 is connected by a spring 261 fixed inside the cylinder 23, allowing the connecting rod 24 to elastically extend and slide within the cylinder 23, accommodating alignment deviations caused by slight deformation of the equipment. An embedded groove 262 at the top of the connecting rod 24 provides sliding space for the locking block 263. A locking groove 264 at the top of the cylinder 23, together with the locking block 263 and the spring 265, forms an automatic locking structure. When the connecting rod 24 is slidably adjusted to a suitable position, the spring 265 pushes the locking block 263 into the locking groove 264, thus fixing and locking the connecting rod 24.

[0046] Specifically, a trigger rod 266 is slidably connected to the inner cavity of the docking rod 24, a trigger block is fixedly connected to the inner cavity of the docking cylinder 25, an abutment plate 267 is fixedly connected to the surface of the trigger rod 266, and an abutment groove 268 is formed on the surface of the locking block 263.

[0047] A trigger rod 266 is slidably installed inside the connecting rod 24, which, together with a trigger block fixed inside the connecting cylinder 25, forms a connection-in-place sensing structure. An abutment plate 267 fixed to the surface of the trigger rod 266 matches an abutment groove 268 on the surface of the locking block 263, achieving mechanical unlocking through a slope-pressing fit principle. When the two sets of connecting sleeves 11 precisely connect the pipes, the trigger rod 266 contacts and presses against the trigger block, causing the abutment plate 267 to shift. Through the slope fit between the abutment plate 267 and the abutment groove 268, the locking block 263 is forced out of the locking groove 264, automatically releasing the locking state of the connecting rod 24.

[0048] Specifically, a spring 269 is fixedly connected to the corresponding side of the trigger rod 266 and is fixedly connected to the inner cavity of the docking rod 24.

[0049] A spring 269 is fixedly connected to one side of the trigger rod 266, and the spring 269 is fixedly connected to the inner cavity of the docking rod 24. When the docking is completed and the trigger rod 266 is disengaged from the trigger block, the elastic restoring force of the spring 269 can quickly pull the trigger rod 266 and the abutment plate 267 to reset, so that the unlocking structure returns to its initial state and is ready for the next pipeline docking trigger unlocking operation.

[0050] Working principle: During operation, the titanium-steel composite pipe to be processed is first placed on the pads 12 inside the connecting sleeves 11 on both sides of the equipment frame 1. The electric push rod 121 inside the pad 12 extends and retracts, driving the sealing plate 122 to rise and fall, providing auxiliary support for the end of the composite pipe. Then, the motor 151 at the bottom of the inner cavity of the equipment frame 1 is started. The output shaft of the motor 151 drives the lead screw 152 to rotate. The lead screw 152 drives the movable block 153 on the surface to make linear displacement through the thread transmission. The movable rods 154 hinged on both sides of the movable block 153 rotate synchronously and push, causing the connecting sleeves 11 on both sides of the top of the equipment frame 1 to slide towards each other, realizing the automatic alignment and approach of the two sets of titanium-steel composite pipes.

[0051] During the sliding process of the connecting sleeve 11, the sliding rod 2 at the bottom of the inner cavity of the connecting sleeve 11 moves synchronously with the sleeve, causing the sliding rod 2 to slide inside the sliding sleeve 21 fixed by the equipment frame 1. The driving block 221 at the top of the sliding rod 2 slides along the trajectory of the driving groove 222 on the surface of the sliding sleeve 21, and drives the sliding rod 2 to rotate under the guidance of the groove. When the sliding rod 2 rotates, it drives the gear 1 223 on the surface to rotate synchronously. The gear 1 223 meshes and drives the gear 2 224 to rotate. The gear 2 224 is linked to the rotation of the jaw disc 1 225. The jaw disc 1 225 meshes and pushes the jaw disc 2 226 to rotate, which in turn drives the gear 3 227 to rotate. The gear 3 227 drives the gear ring 228 and the gear 4 229 to rotate step by step through the meshing transmission, and finally drives the fixed rod 2210 and the positioning plate 13 connected to the fixed rod 2210 to rotate. The positioning plate 13 passes through the through groove 14 on the inner wall of the connecting sleeve 11 and rotates to fit against the outer wall of the composite pipe, realizing the positioning and clamping of the pipe. When the positioning plate 13 is attached to the composite pipe, it is limited by the pipe wall and cannot continue to rotate. At this time, the continuously rotating jaw disc 225 will squeeze the jaw disc 226, causing the jaw disc 226 to slide along the reset rod 2211 and compress the spring 2212. The elastic clutch achieves adaptive buffering, adapting to the clamping requirements of composite pipes with different outer diameters, while avoiding rigid compression damage to the pipe.

[0052] To address the docking error caused by deformation due to long-term use of the equipment, the docking rod 24 inside the cylinder 23 can be pre-adjusted so that the docking rod 24 slides inside the cylinder 23 and stretches the second spring 261. When the docking rod 24 is adjusted to the reference position, the locking block 263 in the embedded groove 262 is locked into the locking groove 264 at the top of the cylinder 23 under the elastic force of the third spring 265, thereby locking and fixing the docking rod 24. When the two sets of composite pipes are precisely aligned, the connecting rod 24 slides into the inner cavity of the connecting cylinder 25 on the other side. The trigger block inside the connecting cylinder 25 contacts and presses against the trigger rod 266 inside the connecting rod 24, pushing the trigger rod 266 to move and compressing the spring 269. The trigger rod 266 drives the abutment plate 267 to move. Through the slope of the abutment plate 267 and the abutment groove 268, the locking block 263 is pressed, causing the locking block 263 to disengage from the groove 264 and releasing the locking state of the connecting rod 24. At this time, the elastic force of the spring 261 drives the connecting rod 24 to automatically reset, preventing the connecting rod 24 from protruding and interfering with subsequent pipe welding.

[0053] Example 3, referring to Figure 1 and Figure 7 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0054] Specifically, an electric push rod 121 is fixedly connected to the inner cavity of the pad 12, and a sealing plate 122 is fixedly connected to the top of the electric push rod 121 and is slidably connected to the pad 12.

[0055] An electric push rod 121 is fixed inside the cavity of the pad 12. A sealing plate 122, which slides with the pad 12, is fixed to the top of the electric push rod 121. The extension and retraction of the electric push rod 121 can drive the sealing plate 122 to rise and fall. After the pipe is placed, the height of the sealing plate 122 can be adjusted according to the pipe specifications to provide precise support for the pipe end and prevent misalignment during pipe connection.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
