[0006] The angle-adjustable clamping module includes an upper half-ring and a lower half-ring. The middle part of the lower half-ring is rotatably connected to the mounting platform via an arc-shaped rail. The ends of the upper half-ring and the lower half-ring are connected by a fastening clamp. Several positioning heads are fixed on the lower half-ring. A cylinder is horizontally fixed on the mounting platform. A U-shaped locking block that cooperates with the positioning head is fixed to the piston rod end of the cylinder. Several upper clamping arms are fixed on the upper half-ring. Each upper clamping arm has a height-adjustable positioning component one. Several lower clamping arms are fixed on the lower half-ring. Each lower clamping arm has a height-adjustable positioning component two.

[0007] A handle is also fixed in the middle of the upper half ring.

[0008] The cylinder is horizontally fixed on the mounting platform by a fixing plate.

[0009] The base plate is also equipped with a control box for controlling the cylinder's movement.

[0010] A limit block is fixed at the end of the guide rail.

[0011] By adopting the above technical solution, the beneficial effects of this utility model are: In this invention, the distance between the two mounting platforms can be adjusted according to actual needs. In addition, the upper and lower half rings of the LNG flexible pipe clamp can also be adjusted in angle as needed. Under the action of the cylinder, the U-shaped locking block is tightly engaged with the corresponding positioning head to achieve reliable locking of the entire angle-adjustable clamping module, thereby meeting the requirements of test clamping.

[0013] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0014] like Figure 1-3 As shown, the clamping device for rapid testing of LNG flexible pipelines includes a base plate 1, on which a guide rail 2 is horizontally fixed. Specifically, a limit block 6 is fixed at the end of the guide rail 2. An adjusting seat 4 is slidably connected to the guide rail 2. The adjusting seats 4 are fixedly connected to the mounting platform 8 via a crossbeam 7. The mounting platform 8 is equipped with an angle-adjustable clamping module 3 for clamping LNG flexible pipelines. A locking screw 5 is also threaded onto the adjusting seat 4. With this structure, the position of the mounting platform 8 can be adjusted by adjusting the position of the adjusting seat 4, thereby meeting the clamping needs of different LNG flexible pipelines.

[0015] In this embodiment, there are two angle-adjustable clamping modules 3, which can clamp both ends of the LNG flexible pipeline. The angle-adjustable clamping module 3 includes an upper half-ring 301 and a lower half-ring 302. The middle part of the lower half-ring 302 is rotatably connected to the mounting platform 8 through an arc-shaped rail 308. The ends of the upper half-ring 301 and the lower half-ring 302 are connected by a fastening clamp 303. Several positioning heads 11 are fixed on the lower half-ring 302. A cylinder 9 is horizontally fixed on the mounting platform 8. Specifically, the cylinder is horizontally fixed on the mounting platform 8 through a fixing plate 13. 9; The piston rod end of cylinder 9 is fixed with a U-shaped locking block 10 that cooperates with positioning head 11; Several upper clamping arms 304 are fixed on the upper half ring 301, and the upper clamping arms 304 have height-adjustable positioning parts 305; Several lower clamping arms 306 are fixed on the lower half ring 302, and the lower clamping arms 306 have height-adjustable positioning parts 307; With this structure, by placing the end of the LNG flexible pipe between the upper half ring 301 and the lower half ring 302, the end of the LNG flexible pipe can be clamped by locking fasteners.

[0016] A handle 309 is also fixed in the middle of the upper half ring 301. This structure allows for convenient adjustment of the angles of the upper half ring 301 and the lower half ring 302.

[0017] The base plate 1 is also equipped with a control box 12 for controlling the action of the cylinder 9. This adopts existing technology. The control box 12 can control the piston rod of the cylinder 9 to extend or retract.
