The invention provides a non-repeated supporting and anti-impact forepoling of a circulating rolling type lifting top beam. The non-repeated supporting and anti-impact forepoling comprises a circulating rolling type lifting top beam assembly, an adjustable top beam assembly supporting frame, a supporting stand column, a sliding type base, a base sliding rail and a supporting frame mounting shaft. A split type lifting top beam unit in the circulating rolling type lifting top beam assembly supports all positions of a top plate in a partitioning mode under the action of foundation supporting force provided by a supporting stand column, and in the supporting process, a forepoling technology method of front lifting supporting and rear lifting removing is adopted for frame moving and supporting. The top beam unit in the middle position is in a contact supporting state all the time, and when the top plate is pressed, the anti-impact supporting plate generates elastic deformation to absorb the impact load. The suppor
