The invention discloses an operating bed inspection device and an inspection method, and relates to the technical field of operating bed inspection. The device comprises a frame, a water tank and a control unit, and a lifting mechanism, an X-direction displacement sensor, a Y-direction displacement sensor and a tension sensor which are connected with the control unit, the water tank is located onthe inner side of the frame and corresponds to the upper portion of the operating bed, and the lifting mechanism is used for driving the water tank to ascend and descend in the vertical direction. Thetension sensor is used for checking the weight of the water tank, the X-direction displacement sensor is used for checking the roll angle of the operating bed, and the Y-direction displacement sensoris used for checking the turnover angle of the operating bed; by implementing the technical scheme, the bearing and each displacement of the operating bed can be automatically inspected, the bearingtest, the displacement test and the fatigue test of the operating bed are carried out, the reliability of operating bed performance inspection is improved, manual recording errors in the detection process can be effectively avoided, accurate online recording is realized, and the operating bed inspection device is simple in structure, convenient to operate, safe and reliable.
