IMPACT LOAD STRIKING DEVICE STRUCTURE STABILITY EVALUATION SYSTEM HAVING THE SAME AND STRUCTURE STABILITY EVALUATION METHOD

摘要

The present invention relates to an impact load striking device, a structure stability evaluation system including the same, and a structure stability evaluation method. Maintaining or restoring the elastic compression of the second fixing bracket positioned there, the moving bracket moving back and forth through the space between the first and second fixing brackets, the compression spring elastically supporting between the second fixing bracket and the moving bracket, and the compression spring It is connected to move integrally with the trigger unit and the moving bracket, and moves forward and backward through the space between the first and second fixing brackets in conjunction with the elastic compression and restoration of the compression spring according to the operation of the trigger unit. Including, the movable body, a ball screw connected to the front and back elongated along the center of the movable body and rotating in forward and reverse directions, fixed to the center of the movable bracket, and a nut block for linearly moving the movable bracket back and forth in conjunction with the rotation of the ball screw, and an impact rod connected to the front of the ball screw and striking the structure.
