The invention discloses a tensioning equipment structure. The tensioning equipment structure is formed by connecting a first centre hole jack and a second centre hole jack in series. The middles of the two centre hole jacks are fixedly connected as a whole through rigid supporting rods, the two jacks are provided with components for clamping and loosening steel tension steel strands respectively, and hydraulic pipelines of the two jacks cross and are connected. When the first jack carries out tensioning, the second jack carries out loosening. When the first jack carries out loosening, the second jack can carry out tensioning. Long-stroke continuous tensioning of an article is achieved through alternate tensioning of the two jacks. The tensioning equipment structure can be conveniently applied to tensioning of a bridge turner, and the tensioning operation of the whole bridge turner is easy and convenient. The jacks used for tensioning are simple in structure and low in cost.
