During the load test of the marine engineering equipment frame, heavy objects are placed inside the marine engineering equipment frame one by one. At this time, under the gravity of the heavy objects, the support plate will slide downward, and the support plate will pressurize one side of the balance plate when sliding. At this time, one side of the balance plate will deflect downward, and the other side of the balance plate will deflect upward. The side of the balance plate that deflects upward will act on the bottom of the push plate. As the heavy objects continue to be added, the downward movement of the support plate will increase, and the deflection angle of the balance plate will gradually increase. At this time, the push plate will The push plate slides upward under the action of the balance plate, and the push plate pushes the extrusion plate to deflect to one side when moving upward, so that the angle between the extrusion plate and the fixing groove gradually increases, and one end of the deflected extrusion plate acts on one side of the marine engineering equipment frame, so that the marine engineering equipment frame can be reinforced by the extrusion of the extrusion plate to prevent the position of the marine engineering equipment frame from shifting due to the addition of heavy objects, thereby causing the marine engineering equipment frame to fall off the test platform, and further affecting the load test of the marine engineering equipment frame, and the pressure between the extrusion plate and the marine engineering equipment frame will increase with the increase of the weight, so as to facilitate improving the fixing effect of the fixing mechanism on the marine engineering equipment frame; 2.

Since the shape of the rotating rod is Z-shaped, the turntable will swing in a circle with the rotation of the rotating rod, so as to improve the fluctuation effect of the sea surface, and then improve the accuracy of the marine engineering equipment frame and the test data. In addition, when the rotating rod rotates, the connecting rod will drive the swing blade to swing back and forth under the action of the rotating rod and the rotating sleeve, so as to make the sea surface in the test range swing irregularly, so as to improve the accuracy of the test results.
