[0020] Example 1
[0021] A flexible pipe flexibility detection device, such as Figure 1-Figure 3 As shown, it includes a workbench 1, and the left and right parts of the workbench 1 are both equipped with a stretching assembly 2, and the stretching assembly 2 includes a driving assembly 21. The left and right parts of the workbench 1 are both equipped with a driving assembly 21, and the driving assembly 21 includes a servo motor. The left and right parts of the workbench 1 are both equipped with a servo motor, and the servo motor output shaft is connected to a screw rod, and the screw rod is threadedly connected to a mounting bracket, and the mounting bracket is connected to a mounting frame 22. The front side of the mounting frame 22 is rotatably connected to a side plate 23, and the lower sides of the front and rear parts of the mounting frame 22 are rotatable. A pulley 24 is dynamically connected, and a bolt 25 is slidably connected to the side plate 23. A power-assisting block is provided on the bolt 25. A fixing component 3 is installed on the mounting frame 22. The fixing component 3 is a detachable connection structure. The fixing component 3 includes a connecting plate 31. A connecting plate 31 is slidably connected to the mounting frame 22. A snap ring 32 is connected to the connecting plate 31. Rubber pads 33 are connected to the left and right sides of the snap ring 32. An adjusting piece 34 is provided on the snap ring 32. A bending test mechanism 4 is provided on the upper middle side of the workbench 1.
[0022] It should be noted that flexible pipes refer to pipe systems that can bend and adapt to different shapes of paths. The main advantage of flexible pipes is their flexibility, which enables them to be installed in a small space and can withstand a certain degree of twisting and stretching without damage. After the flexible pipes are produced, they need to be subjected to flexibility testing to evaluate the pipe's bending ability and ability to restore to its original shape when subjected to external forces. First, the flexible pipe in the initial state is passed through the clamping ring 32, and the size of the clamping ring 32 can be adjusted using the adjusting piece 34 to adapt to the clamping requirements of flexible pipes of different specifications. The clamping ring 32 then clamps the pipe. The material on the surface of the clamping ring 32 is too hard, which may cause damage to the pipe surface during the clamping process. The rubber pad 3 3 can protect the surface of the pipeline and add a buffer layer to avoid damage to the pipeline surface. The fixing components 3 such as the clamping ring 32 are consumables and need to be replaced regularly. The clamping bolt 25 can be pulled out upward to disengage the side plate 23 from the locked state, and the side plate 23 can be rotated outward to expand the inside of the installation frame 22. Then, the connecting plate 31 can be slid outward to remove and replace the connecting plate 31. This installation method makes it easier to replace consumables such as the fixing components 3. Then, a tensile test is performed. The servo motor is turned on, and the rotation of the servo motor output shaft drives the screw to rotate, thereby driving the mounting frame to move. The pulley 24 guides the movement of the adjacent mounting frame, thereby driving the fixing component 3 to move outward, thereby performing a left-right tensile test on the flexible pipeline.
[0023] Example 2
[0024] On the basis of Example 1, Figure 1 、 Figure 2 and Figure 4 As shown, the bending test mechanism 4 includes a drive motor 41, the drive motor 41 is installed on the upper middle side of the workbench 1, a gear 42 is connected to the output shaft of the drive motor 41, and two left-right symmetrical slide rails 43 are installed on the upper middle side of the workbench 1. The inner sides of the slide rails 43 are slidably connected to racks 44, and the racks 44 are engaged with the gears 42. The outer sides of the slide rails 43 are slidably connected to test rods 45, and the test rods 45 are engaged with adjacent racks 44.
[0025] like Figure 1 and Figure 5 As shown, a protective mechanism 5 is also included, and the protective mechanism 5 includes a mounting plate 51. The upper sides of the left and right parts of the workbench 1 are both equipped with front-to-back symmetrical mounting plates 51. Two dampers 52 are connected to the mounting plates 51. Buffer springs 53 are provided inside the dampers 52. A protective plate 54 is connected between the two adjacent dampers 52, and a rubber block is provided on the protective plate 54.
[0026] It should be noted that when a bending test is performed on a flexible pipe, the drive motor 41 is turned on, and the output shaft of the drive motor 41 rotates to drive the gear 42 to rotate, thereby driving the racks 44 on the left and right sides to move. The movement of the racks 44 will drive the adjacent test rods 45 to move. As the test rods 45 move, the flexible pipe will be stretched in the front and back directions to test the curvature of the pipe. As the stretching assembly 2 and the bending test mechanism 4 perform stretching tests on the flexible pipe in the left and right directions and the front and back directions, when the flexible pipe is stretched to the limit, the pipe will break free from the clamping of the clamping ring 32 and bounce outward, and the protective plate 54 can protect the pipe.
[0027] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
