Abstract：In order to solve problems of large labor intensity and low efficiency existed in durability test process of internal injection type single prop with manual loading and unloading method,a set of automatic loading device of durability test of internal injection type single prop was developed.The device uses measurement and control software for industrial personal computer to control servo motor and speed reducer to drive load tooling rotate,realizes operation of lifting and falling prop of internal injection type single prop by the servo motor driver,and automatically control loading process of the prop;uses the servo motor to drive unloading handle to achieve operation of unloading and falling prop.The device can also realize precise control of load speed,torque,position of the motor to prevent overload and locked-rotor of loading mechanism.The test results show that the control device has high control accuracy,fast loading speed,stable and reliable performance,which improves automation level of durability test of the internal injection type single prop.
