| description | The invention discloses a synchronous lifting device with a mechanical self-locking protection function and a control method. The device comprises a hydraulic jack with a mechanical self-locking protection device, a hydraulic pump station, a centralized movable control cabinet and a displacement sensor, wherein the hydraulic jack with the mechanical self-locking protection device comprises the mechanical self-locking protection device and a single-acting hydraulic jack, and the mechanical self-locking protection device is installed on the single-acting hydraulic jack and synchronously operatesalong with the single-acting hydraulic jack to perform synchronous mechanical protection on the single-acting hydraulic jack. According to the device and the method, a nut-screw-structure hydraulic jack is used for replacing a traditional mechanical pressure maintaining type hydraulic jack and a hydraulic jack, the function of the mechanical pressure maintaining type hydraulic jack is achieved through gear meshing transm |
