Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0016] Please see Figure 1 This utility model provides a technical solution for a loading mechanism of a corrugated pipe testing machine: a loading mechanism for a corrugated pipe testing machine includes a support plate 1, a support frame 6 fixedly connected to the middle of the top of the support plate 1, and support seats 5 slidably connected to both sides of the top of the support frame 6. The support seats 5 can support both ends of the corrugated pipe. The support seats 5 are fixedly connected to the interior of each support seat 12, and the support seats 5 are fixedly connected to the interior of each support seat 10. The support frame 6 is provided with an adjustment component 7 that can adjust the relative distance between the two support seats 5. The fixed frame 12 is provided with a fixing component 9 that can clamp the corrugated pipe. The four corners of the bottom of the support plate 1 are fixedly connected to support columns 11, which can provide stable support for the entire device. Guide holes 2 are provided on both sides of the support plate 1. Movable seats 3 are slidably connected to both sides of the top of the support plate 1 and to the top of the guide holes 2. A hydraulic rod 4 is fixedly connected to the top of the movable seat 3. The hydraulic rod 4 can be moved by the movable seat 3, so that the hydraulic rod 4 can detect various parts of the bellows. A drive assembly 8 is provided at the bottom of the support plate 1, which can simultaneously control the two movable seats 3 to move in the same direction.

[0017] Please see Figure 2The adjustment component 7 includes a first motor 71, which is fixedly connected to one side of the support frame 6. One end of the output shaft of the first motor 71 passes through the support frame 6 and is fixedly connected to a bidirectional screw 72. Both ends of the bidirectional screw 72 are threadedly connected to threaded sleeves 73. The top of each threaded sleeve 73 is fixedly connected to a fixing rod 74. The top of the fixing rod 74 is fixedly connected to the bottom of the support base 5. The first motor 71 drives the bidirectional screw 72 to rotate, so that the bidirectional screw 72 and the threaded sleeves 73 at both ends perform threaded transmission, which can drive the fixing rod 74 to move in opposite directions, so that the fixing rod 74 can drive the support base 5 to slide on the top of the support frame 6, and can perform a tensile test on the bellows in the fixed state.

[0018] Please see Figure 3 The drive assembly 8 includes a drive frame 81, which is fixedly connected to the middle of the bottom of the support plate 1. Movable plates 85 are slidably connected to both sides inside the drive frame 81. Support rods 86 are fixedly connected to both sides of the top of the movable plates 85. The top of the support rods 86 passes through the guide hole 2 and is fixedly connected to the bottom of the movable seat 3. A threaded rod 83 is rotatably connected inside the drive frame 81. A second motor 82 is fixedly connected to one side of the drive frame 81 to drive the threaded rod 83 to rotate. A guide sleeve 84 is threadedly connected to the middle of the threaded rod 83. One side of the movable plates 85 is fixedly connected to both sides of the guide sleeve 84. The second motor 82 drives the threaded rod 83 to rotate, so that the threaded rod 83 and the guide sleeve 84 are threadedly transmitted, thereby driving the movable plates 85 on both sides to move. This allows the top of the support rod 86 to slide inside the guide hole 2, facilitating the sliding of the movable seat 3 by the support rod 86. By controlling the rotation of the second motor 82, it is convenient to simultaneously control the movable seats 3 on both sides to move the same distance in the same direction, which facilitates the detection of various parts of the bellows.

[0019] Please see Figure 4The fixing component 9 includes a bidirectional lead screw 91, which is rotatably connected to the top of the inner wall of the fixing frame 12. Both sides of the bidirectional lead screw 91 are threadedly connected to connecting sleeves 94. The bottom of each connecting sleeve 94 is fixedly connected to a connecting plate 96. The bottom of the opposite side of each connecting plate 96 is fixedly connected to a fixing clamp 97. An adjusting block 95 is rotatably connected to the middle of the top of the fixing frame 12. The bottom of the adjusting block 95 is fixedly connected to a first bevel gear 92. The middle of the bidirectional lead screw 91 is fixedly connected to a second bevel gear 93 that meshes with the first bevel gear 92. By rotating the adjusting block 95, the first bevel gear 92 is driven to rotate, so that the first bevel gear 92 and the second bevel gear 93 mesh and drive each other, which can drive the bidirectional lead screw 91 to rotate, so that the bidirectional lead screw 91 and the connecting sleeves 94 on both sides can perform threaded transmission, which drives the two fixing clamps 97 to move in opposite directions, so that the two fixing clamps 97 can clamp and fix the bellows fitted on the outside of the connecting rod 10, preventing the bellows from falling off when pulled.

[0020] The working principle and usage process of this utility model are as follows: First, the two ends of the bellows are respectively fitted onto the outside of the two connecting rods 10. Then, the adjusting blocks 95 on the fixing frame 12 are rotated. The adjusting blocks 95 drive the first bevel gear 92 to rotate, so that the first bevel gear 92 meshes with the second bevel gear 93, which drives the bidirectional screw 91 to rotate at the top of the fixing frame 12. The bidirectional screw 91 and the connecting sleeves 94 on both sides are threaded, which drives the two fixing sleeves 97 to move in opposite directions, so that the two fixing sleeves 97 can clamp and fix the bellows fitted onto the outside of the connecting rods 10. Then, the first motor 71 is controlled to drive the bidirectional screw 72. Rotation causes the bidirectional screw 72 to transmit power between the threaded sleeves 73 on both sides, driving the two support seats 5 to move in opposite directions. This allows the bellows in a fixed state to be stretched and subjected to a tensile test. Then, the second motor 82 is controlled to drive the threaded rod 83 to rotate, causing the threaded rod 83 to transmit power to the guide sleeve 84. This causes the movable plate 85 to slide inside the drive frame 81, and the support rod 86 to slide inside the guide hole 2. The support rod 86 drives the movable seat 3 to move, allowing the two movable seats 3 to slide in the same direction and adjust the detection position on the bellows. By controlling the hydraulic rod 4 to extend simultaneously, the bellows can be subjected to a compression test.

[0021] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
