Of course, its specific installation method and control principle are all existing technologies, and are not the invention points of the present disclosure, so they will not be elaborated here.

[0072] The lifting mechanism provided in this embodiment includes an electric hoist 160 installed at both ends of the top of the frame 100 and a pulley assembly installed in the middle position of the top of the frame 100. The two electric hoists 160 are connected to the control unit 170 so that the two electric hoists 160 can be started synchronously by controlling the control unit 170, and each electric hoist 160 is configured with a wire rope 150. The wire rope 150 passes around the pulley assembly and is connected to the water tank 130. The electric hoist 160 is started by controlling the control unit 170 to achieve the retraction and release of the wire rope 150, and the tension sensor 140 is installed on the wire rope 150.

If the pin 103 is arranged horizontally (i.e. Figure 1 X direction), so that the connecting rod is installed on the side of the frame 100 and can move in the vertical direction ( Figure 1 The second displacement sensor 180 is rotated in the Y direction to the top of the operating table, thereby forming a storage state and a testing state of the second displacement sensor 180, which are also within the protection scope of the present invention.

[0099] An electromagnet 290 for fixing the connecting rod 200 is provided on the mounting groove of the fixing block 102. The electromagnet 290 can be connected to the control unit 170 so that the electromagnet 290 can absorb the connecting rod 200 after being energized, so that the second displacement sensor 180 is arranged above the operating table for flipping inspection when in the inspection state. The connecting rod 200 is fixed by the electromagnet 290, and the structural design is simple. At the same time, in order to facilitate the installation and disassembly between the first slide rail 190 and the connecting rod 200, the two ends of the first slide rail 190 are respectively The first slide rail 190 is detachably connected to the free end of the connecting rod 200 through an elastic pin 191, and is of course not limited to this.

[0106] On the other hand, this embodiment also provides a method for checking the translation of an operating table, comprising the following steps:

[0107] After the control water tank 130 is lifted to the top of the operating table inspection device, the operating table top is controlled to move longitudinally or transversely by the control unit 170;

[0108] Then, the longitudinal translation distance of the operating table is measured by the third displacement sensor 210, or the lateral translation distance of the operating table is measured by the fourth displacement sensor 280;

[0109] Finally, the obtained translation distance is compared with the set operating table translation distance to complete the operating table translation inspection.

[0110] The specific implementation method of the lateral translation detection of the above-mentioned operating table is as follows: by controlling the slider on the third slide rail 270 to move up and down, the fourth displacement sensor 280 is aligned with the side of the operating table top, and then the operating table is controlled to perform a lateral translation action along the X direction, the lateral translation distance of the operating table can be measured, so as to automatically detect the lateral translation distance and the longitudinal translation distance of the operating table.
