The reinforced concrete structure damage detection device detects the damage degree of the reinforced concrete structure through an ultrasonic flaw detector, and then starts the electric push rod 1 and the electric push rod 2 through the numerical controller, so that the electric push rod 1 pushes the telescopic frame to extend the limit rod, so that the slider on the electric push rod 2 drives the moving platform and the moving rod to rise, both of which can indirectly raise the ultrasonic flaw detector, so as to achieve the purpose of autonomously completing the detection operation, thereby improving the intelligence of the detection device. At the same time, the detection height of the detection device is not limited, and the reinforced concrete structure located at a high place can be detected without manual auxiliary operation, saving time and effort.
