The sample platform is installed on the frame side frame and the crossbeam is horizontally installed on the top of the frame. The impact testing device includes an impact hammer suspended on the crossbeam and a camera fixed on the crossbeam. However, the existing device still has some deficiencies. When detecting the cable bridge, the existing device usually places the cable bridge in front of the baffle and impacts it with the swinging impact hammer. However, when the cable bridge is installed, it is usually fixed on the surface of the wall. If the cable bridge is subjected to external impact or collision from the side, it cannot be supported by the wall surface, resulting in inaccurate test results. Therefore, we propose a cable bridge impact testing machine to solve the above problems. UTILITY MODEL CONTENTS
