And prestress tensioning device is used for tensioning position of bundle

The utility model discloses a prestress tensioning device for tensioning a bundle position. Wherein the tensioning telescopic cylinder (90) is used for generating prestress tensioning acting force, the winch device is arranged at the position of a tensioning bundle and used for adjusting the position of the tensioning telescopic cylinder (90), and the pressing plate (91) is arranged between the tensioning telescopic cylinder (90) and the winch device and used for fixedly connecting the tensioning telescopic cylinder (90). The prestress tensioning acting force is achieved through the tensioningtelescopic cylinder (90), the tensioning bundle position of the tensioning telescopic cylinder (90) is adjusted through the pressing plate (91) and the winch device, the tensioning telescopic cylinder is not directly used any more, and therefore the prestress tensioning efficiency is improved. 一种用于张拉束位置的预应力张拉装置，包含有用于产生预应力张拉作用力的张拉伸缩缸(90)、设置在张拉束位置上并且用于调节张拉伸缩缸(90)位置的卷扬车装置、设置在张拉伸缩缸(90)与卷扬车装置之间并且用于对张拉伸缩缸(90)进行固定连接的压板(91)，通过张拉
