　　突起路标耐冲击测试装置操作步骤：

　　★准备：调整底座的螺栓使其底面处于水平，将待测突起路标放到底座下侧并与其底面平行，如底面下侧高度不够，则需再次调整底座的螺栓，甚至用其它等厚度的块状物垫高底座的高度。将不锈钢导管安装到底座的安装座内，将环形开关置于锁止状态，通过环形开关使支撑三角在圆形管内形成钢球座即支撑三角的一臂处于悬臂状态以支撑钢球。

　　★落差高度标定：用卷尺测量突起路标上表面与支撑三角水平悬臂之间的距离。

　　★试验：将钢球置于钢球座内左手扶住钢球座的同时，右手快速往下拨环形开关即释放处于锁止状态的支撑三角，确保钢球自由落下冲击突起路标。

　　★测量：用标准长度测量量具，测量突起路标表面裂纹的长度和面积。并记录测量数据。

　　Protruding road sign impact tester operation steps

　　★Preparation:adjust the bolt of the base so that the bottom surface is level.Place the road markings to be tested on the lower side of the base and parallel to the bottom surface.If the height of the bottom side is not enough,you need to adjust the bolts of the base again,or even use other blocks of equal thickness.The height of the base is high.The stainless steel conduit is mounted in the mount of the base,ａnd the ring switch is placed in a locked state,ａnd the support triangle is formed in the circular tube by the ring switch to form a steel ball seat,that is,an arm of the support triangle is in a cantilever state to support the steel ball.

　　★Drop height calibration:Use a tape measure to measure the distance between the upper surface of the raised road sign and the horizontal cantilever of the support triangle.

　　★Test:While placing the steel ball in the steel ball seat and holding the steel ball seat with the left hand,the right hａnd quickly dials the ring switch to release the support triangle in the locked state,ensuring that the steel ball freely falls under the impact protruding road sign.

　　★Measurement:Measure the length and area of surface cracks on the raised road markings with a standard length measuring gauge.And record the measurement data.

　　突起路标耐冲击测试装置结构：

　　主要由钢球、钢球座（支撑三角和圆形管）、环形开关、不锈钢导管、底座和可调整高度螺钉等组成。
