High speed railway ballastless track pre-tensioning method flow unit production line

Abstract

The invention provides a high speed railway ballastless track pre-tensioning method flow unit production line. The high speed railway ballastless track pre-tensioning method flow unit production line comprises a tension station, a vibration compaction station, a maintenance station, a relaxation station and a demolding station, wherein the tension station, the vibration compaction station, the maintenance station, the relaxation station and the demolding station are fixedly arranged in sequence, the production line is provided with track template molds which works in coordination with the stations, all the stations are fixed on the ground surface through a support in a suspended mode, and are coordinated with a mobile type transporting cart for transporting a track plate mold and/or a track plate to transport the track plate mold and/or the track plate to work stations. According to the high speed railway ballastless track pre-tensioning method flow unit production line, all the fixed stations are arranged in the production sequence and fixed on the ground surface in a suspended mode, and the transporting cart is arranged to move along center lines at the inner sides of all the work station and to transport the track plate mold and/or the track plate to the work stations, so that the stationary track plate mold and/or the track plate moves along the production line in the work sequence as the transporting cart moves; by the coordination of a specially arranged control system, the automatic and intelligent production of the track plate is achieved. The production cost is reduced, the product quality is guaranteed, and the working efficiency is greatly improved.

Description

technical field [0001] The invention relates to a track slab production line for high-speed railways, in particular to a high-speed railway ballastless track slab pretensioning assembly line production line capable of fully automatic production of high-speed railway ballastless track slabs. Background technique [0002] The main process of the prior art pretensioning production line for high-speed railway ballastless track slabs includes several processes such as steel bar tensioning, vibration pouring, curing, tensioning and demoulding. The current process mainly adopts the production process of fixed pedestal, fixed bottom mold, double-side mold (one set of mold with two sets of side plates), multi-mold one-time centralized tensioning, separate steam curing, and separate casting. The process must be completed on a pedestal. The main production equipment involved are: tooling mold, tensioning system (including pre-tensioning system), vibration forming system, track plate lo...

Problems solved by technology

[0005] The tensioning process of this process uses several pedestals to be tensioned at the same time, that is, one tensioning movable beam drives multiple steel bars to tension at the same time, and the final control is the total tension of all steel bars. Therefore, if any tension beam on one side appears Deformation, errors during pre-tensioning, or errors in the synchronous control of the displacement of the tensioning cylinders will bring large errors to the tension of individual steel bars, and the control accuracy is low, which directly affects the production quality of the track slab

At the same time, there are certain safety hazards in this process.
