A servo motor (5-2) is disposed inside the connecting frame (5-1), and a rotating rod (5-3) is fixedly disposed at one end of the output shaft of the servo motor (5-2) through a coupling. One end of the rotating rod (5-3) is fixedly connected to one side of the hydraulic clamp (2-6) on the right side. A ring rotating frame (5-7) is fixedly disposed on one side of the hydraulic clamp (2-6) on the right side, and one side of the ring rotating frame (5-7) is rotatably connected to one side of the connecting frame (5-1). A limit frame (6-2) is movably disposed inside the rotating frame (1-5). A miniature electric cylinder (6-3) is also disposed inside the rotating frame (1-5), and the driving end of the miniature electric cylinder (6-3) is fixedly connected to the top of the limit frame (6-2). The top end of the swing arm (1-4) is provided with a rotating shaft (6-1), and the two ends of the rotating shaft (6-1) are rotatably connected to the two sides inside the limiting frame (6-2). Both ends of the rotating shaft (6-1) are provided with limiting holes (6-4) that cooperate with the limiting frame (6-2). Specific steps for pull-out torsion test of anchor body: Step 1: Place the anchor body on the support bracket. The anchor section of the anchor body is located on the left side of the pull-out bearing plate (2-5). The length of the anchor body used for the test shall not exceed the maximum distance between the two hydraulic clamps (2-6). Step 2: Open the hydraulic control system (4-1). Through the hydraulic control system (4-1), control the drive ends of the pull hydraulic cylinder (2-1) and the tension hydraulic cylinder (2-2) to drive the two hydraulic clamps (2-6) to move closer to the anchor bolt sections (3-1) on both sides. At the same time, control the two clamping plates (5-4) inside the hydraulic clamps (2-6) to move closer to each other. Use the two clamping plates (5-4) inside the two hydraulic clamps (2-6) to clamp the anchor bolt sections (3-1) on both sides. Step 3: Set the control parameters of the servo motor (5-2), drive the rotating rod (5-3) to rotate through the output shaft of the servo motor (5-2), and use the rotating rod (5-3) to control the rotation of the hydraulic clamp (2-6) on the right side. At the same time, input the hydraulic control parameters into the hydraulic control system (4-1), and control the drive end of the pull-out hydraulic cylinder (2-1) to reset through the hydraulic control system (4-1) to perform a pull-out torsion test on the anchor body. Step 4: End the experiment and save the experimental data.
