Abstract

The invention provides a synchronous tensioning and releasing control system for pre-tensioned track boards, which comprises a pedestal, a plurality of moulds, transverse tensioning cross beams, longitudinal tensioning cross beams and hydraulic actuators, wherein the track boards are placed on the moulds; the hydraulic actuators are located on the inner surface of a tunnel wall outside the pedestal; the transverse tensioning cross beams and the longitudinal tensioning cross beams are connected with the corresponding hydraulic actuators respectively; the moulds are transversely and longitudinally arranged on the pedestal to form a plurality of transverse mould rows and a plurality of longitudinal mould rows on the pedestal; and the transverse mould rows and the longitudinal mould rows are arranged uniformly. The synchronous tensioning and releasing control system for the pre-tensioned track boards solves the problems that conventional track boards cannot be tensioned and released synchronously and the control accuracy, the production efficiency and the yield are low. The synchronous tensioning and releasing control system for the pre-tensioned track boards can meet the production requirements for synchronous or independent tensioning and releasing of transverse and longitudinal pre-stressed reinforcements of track boards, realizes accurate control of a synchronous tensioning and releasing control process, can reach the pre-tensioning force control accuracy of +/-1%, and greatly increase the production efficiency and the yield of track boards.

Description

technical field [0001] The invention belongs to the field of tensioning systems, and in particular relates to a synchronous tensioning and releasing control system for pre-tensioning track plates. Background technique [0002] The prestressed tensioning technology in the mass production process of the track slab is the core of the quality control of the track slab. The key to the overall prestressed tension and the quality of the tension depends on the safety and accuracy of the tensioning system. The existing track slab yards all adopt the one-dimensional tensioning technology from Germany or Japan. The tensioning system is mainly to meet the requirement of only one-dimensional prestressed steel bars for the previous CRTSⅠ and CRTSⅡ track slabs. The control process is for the track The one-dimensional direction prestressed reinforcement of the slab adopts the tensioning process of front and rear simultaneous tensioning, which has low control precision, high damage rate of p...
