Embodiment Construction
[0009] Depend on figure 2 It can be seen that the device has two double-acting cylinders, one is the loading cylinder 8, and the other is the tested cylinder 9, the two ends of the loaded cylinder 8 and the tested cylinder 9 are respectively connected to hydraulic pipelines, and the swing arm 10 is installed through a hinge. On the fixed bracket 11, the swing arm is eccentric A, the cylinder body of the loading cylinder 8 is mounted on the fixed bracket 12 through a hinge, and the piston rod is mounted on one end of the swing arm 10 through a hinge; the cylinder body of the tested oil cylinder 9 is mounted on the swing arm through a hinge 10 at the other end, the piston rod is mounted on the fixed bracket 13 through a hinge. When the solenoid valve is at the right end, hydraulic oil of the same pressure is input into the end of the rodless cavity of the loading cylinder 8 and the measured cylinder 9, and the two cylinders act on both ends of the swing arm 10 with the same for...
