The invention relates to a movable supporting pillar, which comprises a moving trolley and a columnar supporting body, wherein the moving trolley comprises a top surface and a bottom surface, the bottom surface is provided with a plurality of rollers, the top surface and the bottom surface are connected through a vertical column, the center of the top surface and the bottom surface is provided with a vertical guiding hole for placing the columnar supporting body, the periphery of the bottom portion of the columnar supporting body is provided with a plurality of lug rings, each lug ring is connected to a vertical supporting column, and a resetting resilient device capable of jacking the columnar supporting body is arranged below the supporting columns. According to the present invention, the structure is simple, and the use is easy; when the segment of the ship requires supporting, the supporting pillar is placed on the bottom portion of the segment, the columnar supporting body is pressed under the gravity effect, and the bottom plate bears against the ground so as to support the ship segment through the columnar supporting body; and when the work is completed and the supporting pillar is not required, the columnar supporting body loses the pressure, and the supporting pillar is lifted to leave the ground under the effect of the resetting spring, such that the rollers of the movable trolley support the whole supporting pillar, and the single person can perform the movement of the supporting pillar.
