Title:
TENSIONING DEVICE FOR PREFABRICATED TRACK SLAB AND SYNCHRONOUS RELAXATION DEVICE FOR PRE-TENSIONED PREFABRICATED TRACK SLAB
Document Type and Number:
WIPO Patent Application WO/2018/028555
Kind Code:
A1
Abstract:
Disclosed is a tensioning device for a prefabricated track slab, comprising: a side face tensioning mechanism (3), an end face tensioning mechanism (4), a power mechanism (2) connected to the side face tensioning mechanism (3) and the end face tensioning mechanism (4), and a control mechanism (1). In the tensioning device for the prefabricated track slab, a plurality of tensioning units are tensioned in the directions of end and side dies at the same time, so that the efficiency of tensioning is improved and the production cycle is shortened. Disclosed is a synchronous relaxation device for a pre-tensioned prefabricated track slab, comprising: an end relaxation mechanism (10), a side relaxation mechanism (20), a power mechanism (30) connected to the end relaxation mechanism (10) and the side relaxation mechanism (20), a control mechanism (40), and a die positioning device (50). The synchronous relaxation device for the pre-tensioned prefabricated track slab realizes the synchronous relaxation of a pre-stressed steel reinforcement in the longitudinal direction and the horizontal direction, so that the efficiency of relaxation is improved and the production cycle is shortened.
