The invention discloses a device and a method used for helping replace a plate head of a weaving machine. The device comprises an expansion roller lifting mechanism and a movable device, wherein the expansion roller lifting mechanism comprises a hydraulic cylinder, a lower limiting bracket, a guide rail slide block assembly and a plug pin; the hydraulic cylinder is placed on the lower limiting bracket; an expansion roller base is lifted and dropped through the hydraulic cylinder; as an expansion roller is arranged on the expansion roller base, the expansion roller moves synchronously when the expansion roller base is lifted or dropped. As the expansion roller is lifted through such the machinery, manpower is reduced, and the replacing efficiency of the plate head of the weaving machine is added; as the expansion roller base when being lifted to the highest point can provide mechanical limitation protection through the plug pin, the expansion roller is guaranteed to not fall in the process of replacing the plate head of the weaving machine, and the work safety is improved; as the movable device can move back and forth, the movable device can help replace plate heads of multiple weaving machines, and cost is saved efficiently.
