Beschreibung
Zusammenfassung:	The invention provides a novel prestressed track plate tensioning device. The novel prestressed track plate tensioning device comprises a transverse tensioning unit and a longitudinal tensioning unit,wherein the longitudinal tensioning unit is used for tensioning longitudinal prestressed steel bars in a track plate mold, and the transverse tensioning unit is used for tensioning transverse prestressed steel bars in the track plate mold; and the longitudinal tensioning unit and the transverse tensioning unit both comprise a plurality of steel bar tensioning and locking mechanisms, spacing adjusting mechanisms are arranged between the steel bar tensioning and locking mechanisms of the transverse tensioning unit, and spacing between every two adjacent steel bar tensioning and locking mechanisms is changed through the spacing adjusting mechanisms. According to the novel prestressed track plate tensioning device, the spacing between the steel bar tensioning and locking mechanisms is flexibly changed through the spa
