Beneficial effects of the present invention:

The invention abandons the testing equipment used in the existing industry, and develops a testing device that uses a hydraulic system for installation and lifting, with large output torque, stable and controllable output. Use the high power generated by the hydraulic system to push the oil cylinder, the oil cylinder drives the rack, and the rack drives the gear to rotate, so that the equipment can be smaller in size and the torque to drive the rotation is larger. At the same time, make full use of the buffer performance of the hydraulic system, and use PLC to control the speed and buffer in place of the hydraulic system.

Due to the large bending speed and torque at ±90°, if servo motor + PLC control is used, a larger power servo motor is required and the cost is more expensive. Utilizing the hydraulic system of the present invention, the clamping system can be lowered to the ground before installation, and lifted to the rotating position after the sample is installed.
