[0002] With the acceleration of global carbon neutrality, ammonia, as a zero-carbon fuel, has broad application prospects in the shipping industry, driving the continued growth in market demand for liquid ammonia and liquefied gas carriers (such as large liquefied gas carriers VLGC / VLAC). High-end shipbuilding companies are focusing on developing green, environmentally friendly, energy-efficient 93,000 cubic meter LPG dual-fuel liquid ammonia carrier construction technologies, involving key core technologies such as independent A-type tank integral lifting, containment systems, and cryogenic welding processes. In the liquid cargo system and pipeline installation and testing phases, stable, precise, and damage-free clamping of flexible pipelines is a crucial step in ensuring testing quality and construction efficiency.

[0003] In the current process of inspecting ship pipelines, especially when inspecting flexible pipelines (such as hoses or connecting pipes used in liquid ammonia transport ships), the traditional rigid clamping method is prone to pipeline deformation, damage or unstable clamping, thus affecting the technical problems of inspection accuracy and operational safety. Summary of the Invention

[0018] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0019] Please see Figure 1-7As shown, the adjustable clamping device for pipeline inspection includes: a support base 1, and a support plate 2 is fixedly connected to the upper surface of the support base 1; The support plate 2 is provided with a flexible clamping component 3, which consists of a support tube 301 and an annular bladder 302 disposed on the surface of the support tube 301. The annular bladder 302 can contract and expand to clamp the flexible pipeline 6. The clamping control component 4 consists of a fixed cylinder 401 and a control unit. The fixed cylinder 401 is connected to the flexible clamping component 3 via a connecting air pipe 403 and is used to control the expansion and contraction of the annular bladder 302.

[0020] To address the problem that existing pipe clamping devices are ineffective at securing flexible pipes and are prone to excessive deformation and damage during the clamping process, this application designs a flexible clamping component 3. This component 3 effectively expands and clamps the flexible pipe 6 from within. Furthermore, a clamping control component 4 is included. The combined use of the flexible clamping component 3 and the clamping control component 4 effectively controls the force during expansion clamping, thus preventing deformation and damage caused by excessive force. This design is particularly suitable for testing flexible pipes 6.

[0021] One end of the support tube 301 is located on the side wall of the support plate 2 and is rotatably connected to the support plate 2. The support tube 301 is also provided with a rotation adjustment component 5 at one end, which is used to make the support tube 301 rotate and adjust.

[0022] Several annular bladders 302 are provided, and the annular bladders 302 are fixed at equal intervals on the arc-shaped outer wall of the supporting tube 301. The annular bladders 302 are interconnected with the inner cavity of the supporting tube 301. With this technical solution, when testing is required, the flexible tube 6 to be tested can be sleeved on the outer surface of the supporting tube 301, and then the flexible tube 6 is expanded and clamped by the expansion of the annular bladders 302, which plays a role in fixing it. Since the annular bladders 302 are used as a fixing means, the flexible tube 6 can be effectively protected. Compared with ordinary metal claws and clamps, damage to the flexible tube 6 can be effectively reduced, and flattening and deformation can be avoided, which is beneficial to the testing of the flexible tube 6.

[0023] Preferably, the annular bladder 302 is made of elastic rubber material and has an embedded reinforcing fiber layer to improve its pressure resistance and service life, and to prevent rupture during repeated expansion and contraction.

[0024] A connecting slide cylinder 402 is fixedly connected to one end of the fixed cylinder 401. Support legs 405 are fixedly connected to both ends of the fixed cylinder 401 and the connecting slide cylinder 402. The support legs 405 are fixedly installed on the upper surface of the support base 1. A movable piston 406 is slidably connected in the inner cavity of the fixed cylinder 401. Through this technical solution, the movement of the movable piston 406 can push the gas in the inner cavity of the fixed cylinder 401 into the interior of the annular bladder 302 through the connecting air pipe 403, causing the annular bladder 302 to expand and achieve the fixing function. Furthermore, the interior of the fixed cylinder 401 can also be filled with other expansion media, such as pure water or hydraulic oil.

[0025] A pressure gauge 404 is also fixedly installed at one end of the inner cavity of the fixed cylinder 401. The pressure gauge 404 allows for easy observation of the pressure in the inner cavity of the fixed cylinder 401, thereby timely judgment of the expansion force of the annular bladder 302 and control of the clamping force.

[0026] The control unit consists of a movable slider 408 disposed in the inner cavity of the connecting slide 402 and a control spring 407 connected to the movable piston 406. The movable slider 408 and the control spring 407 are fixedly connected. Through this technical solution, the movement of the movable slider 408 can cause the control spring 407 to contract, thereby applying the elastic force generated by the contraction of the control spring 407 to the movable piston 406, generating pressure, thereby controlling the expansion force of the annular bladder 302.

[0027] A guide protrusion 409 is fixedly provided on the inner wall of the connecting slide cylinder 402, and a guide groove that cooperates with the guide protrusion 409 is provided on the side wall of the movable slider 408, so that the movable slider 408 can slide in a straight line and avoid rotation.

[0028] The movable slider 408 also has an internal cavity. A threaded sleeve 410 is fixedly connected to the internal cavity of the movable slider 408. A screw 411 is rotatably connected to the inner side wall of the connecting cylinder 402. The screw 411 passes through the threaded sleeve 410 and is threadedly engaged with the threaded sleeve 410. A first bevel gear 412 is fixedly connected to the arc-shaped wall of the screw 411. An adjusting knob 413 is rotatably connected to the side wall of the connecting cylinder 402. One end of the adjusting knob 413 extends into the connecting cylinder 402. Inside the cavity, a second bevel gear 414 is fixedly connected to one end of the adjusting knob 413. The second bevel gear 414 meshes with the first bevel gear 412. Through this technical solution, manually rotating the adjusting knob 413 can drive the second bevel gear 414 to rotate, which in turn drives the first bevel gear 412 to rotate. The rotation of the first bevel gear 412 can drive the screw 411 to rotate, which in turn drives the threaded sleeve 410 to move, thereby controlling the movement of the sliding block 408.

[0029] The rotation adjustment component 5 includes a first rotating rod 501, a first gear 502, a second rotating rod 503, and a second gear 504. One end of the first rotating rod 501 is fixedly connected to one end of the support tube 301. The first gear 502 is fixedly connected to the arc-shaped wall of the first rotating rod 501. One end of the second rotating rod 503 is located on the side wall of the support plate 2 and is rotatably connected to the support plate 2. The second gear 504 is fixedly connected to the arc-shaped wall of the second rotating rod 503. An adjustment disc 505 is fixedly connected to one end of the second rotating rod 503. The first gear 502 and the second gear 504 mesh with each other. Through this technical solution, when it is necessary to adjust the angle of the fixed flexible pipeline 6, the adjustment disc 505 can be manually rotated, thereby driving the second gear 504 to rotate, which in turn drives the first gear 502 to rotate, thereby causing the first rotating rod 501 to rotate, which in turn causes the support tube 301 to rotate, and thus drives the flexible pipeline 6 to rotate, thereby realizing the function of adjusting the angle.

[0030] Furthermore, the support plate 2 is also provided with locking bolts for fixing the rotation adjustment component 5. By tightening the bolts, the rotation adjustment component 5 can be locked.
