Determining the compression capacity of pipe sections in test specimens is a crucial step in this process.

[0003] The length of the pipe specimen may lead to unstable pipe fixation, resulting in inaccurate deformation measurement data. In order to further ensure the accuracy of deformation measurement data during the test, it is necessary to solve the pipe fixation problem so that the measurement results of pipe section compression are more accurate.

A square groove 104 is formed at the bottom of the square block 103, and the inner wall of the square groove 104 is slidably connected to the upper outer wall of the lower fixing frame 2, thereby achieving height adjustment of the fixing device and facilitating the fixing of pipes of different lengths. A circular shaft block 105 is fixedly connected to the outer right side of the bottom end of the square block 103, facilitating threaded connection with a first hand screw 107. A threaded through hole 106 is formed in the middle of the circular shaft block 105, and a first hand screw 107 is threadedly connected to the inner wall of the threaded through hole 106 to fix the height of the fixing device. The bottom end of the upper fixing frame 1 has a... The device is provided with a threaded through hole 102. The inner wall of the threaded through hole 102 is threadedly connected to the outer wall of the pipe fixing screw 3. Rotating the pipe fixing screw 3 fixes the pipe to be tested. The lower fixing frame 2 has a threaded through hole 102 in the middle of its outer side. The lower end of the lower fixing frame 2 is fixedly connected to a rotating disk 201, which drives the entire device to rotate and adjust the direction of the pipe for easy measurement. The bottom center of the rotating disk 201 is fixedly connected to a rotating shaft 206. The lower outer wall of the rotating shaft 206 is rotatably connected to a base 202 to realize the rotation of the rotating disk 201. The upper surface of the base 202 has a groove 208 near the edge, which cooperates with a second hand screw 207 to fix the rotating disk 201. The upper surface of the rotating disk 201 has a threaded through hole 204 near the edge. The inner wall of the threaded through hole 204 is threadedly connected to a second hand screw 207 to fix the rotating disk 201.

[0031] The pipe fixing screw 3 has a insertion hole 301 near its center end, which is slidably connected to the outer wall of the mounting block 4. A semi-circular block 302 is fixedly connected to the inner wall of the insertion hole 301. A semi-circular groove 401 is formed on the outer wall of the mounting block 4, and the semi-circular groove 401 is slidably connected to the semi-circular block 302 to prevent the mounting block 4 from rotating within the insertion hole 301. A pipe clamping block 402 is rotatably connected to the middle of the end of the mounting block 4 away from the pipe fixing screw 3, and the pipe clamping block 402 can rotate on the mounting block 4.

A circular hole 205 is opened in the middle of the upper surface of the rotating disk 201. A convex shaft 501 is fixedly connected to the bottom of the central block 5. The inner wall of the circular hole 205 is slidably connected to the outer wall of the convex shaft 501, fixing the central block 5 in the middle of the rotating disk 201. The pipe is fitted on the central block 5, which can quickly find the center of the pipe placement, making it easy for the pipe clamping blocks 402 to fix the pipe and improve the stability of the pipe fixation.

[0032] The lower fixed frame 2 has a limit block 203 fixedly connected to the outer left and right walls of the middle part, which cooperates with the lower end of the square block 103 to limit the minimum height of the device. The end of the first hand screw 107 near the lower fixed frame 2 is designed with a flat head. The upper right outer wall of the lower fixed frame 2 is frosted, which can better fix the overall height of the device and ensure stability. The end of the second hand screw 207 near the base 202 is designed with a flat head. The bottom of the groove 208 is frosted, which can better fix the rotating disk 201 and ensure overall stability. The base 202 is installed on the ring stiffness testing machine to measure the longitudinal compression of the pipe. When the arc surface of the pipe clamp 402 contacts the pipe, the upper and lower planes should be kept horizontal for easy fixation.

[0033] Working principle: Based on the pipe to be tested, a suitable central block 5 is placed in the center of the rotating disk 201. A suitable mounting block 4 is inserted into the mounting hole 301 of the pipe fixing screw 3. Different pipe clamps 402 are adapted to ensure the stability of the fixation. The pipe is placed on the outside of the central block 5 to facilitate quick positioning of the pipe's placement center. The square groove 104 is slidably connected to the lower fixing frame 2. According to the pipe height, the height of the device is manually adjusted. The hand screw 107 is tightened, and the threaded through hole 106 is threadedly connected to the hand screw 107. The end of the hand screw 107 is in contact with the outer wall of the lower fixing frame 2. Due to friction, the overall height of the fixing device is adjusted. The pipe fixing screw 3 is tightened, and the threaded through hole 102 is threadedly connected to the pipe. The pipe clamp 402 moves towards the center of the pipe when the pipe clamp 402's arc surface is about to contact the pipe. The upper and lower planes should remain horizontal and can be manually adjusted to facilitate pipe fixation and ensure stability. After the pipe clamp 402 has fixed the pipe, the rotating disk 201 can be rotated as needed to adjust the pipe's direction, since the rotating shaft 206 is rotatably connected to the base 202. Then, the hand screw 207 is tightened, and the threaded through hole 3 204 is threadedly connected to the hand screw 207. The end of the hand screw 207 fits against the inner bottom of the groove 208. Due to friction, the rotating disk 201 is fixed. After the pipe is fixed, the ring stiffness testing machine is started to transmit the longitudinal deformation data of the pipe to the computer.
