[0003] The existing force sensor is set on the swing support frame. The steel rope is pressed on the guide wheel swing frame to make the guide wheel swing frame swing back and forth axially during transportation, and the guide wheel swing frame is radially pressed on the force sensor to transmit the steel rope tension. Since the swing amplitude of the guide wheel swing frame is not very large, the guide wheel swing frame transmits the force radially to the force sensor through direct force, resulting in inaccurate force on the force sensor and the inability to accurately detect the steel rope tension, which affects the stable production of the steel rope and affects the production quality of the steel rope.
