Flexible assembly line for producing ballastless track slabs by pretensioning

Abstract

The flexible production line for producing ballastless track slabs by the pretensioning method of the present invention improves and optimizes production by adding auxiliary tracks such as outer track, inner track and cross track on the basis of the existing circular production track, and adopts a double-channel double-station design to improve and optimize production. In the rapid response capability, the equipment is ready for use. At the same time, it is compatible with multiple specifications of ballastless track slab molds to run on the same line to produce track slabs, and can realize simultaneous co-line production of two specifications of molds, which improves equipment utilization and reduces equipment investment. The automated equipment is intelligently controlled by the central control room. The use of flexible process procedures can adjust the ability of the production line to run, which is more flexible. The double-station design and the steam-curing module (steam-curing room) that can be increased or decreased can flexibly adjust the output of the track plate to match the progress of the project.

Description

technical field [0001] The invention relates to a track slab production line for high-speed railways, in particular to a flexible assembly line for producing ballastless track slabs by pretensioning. Background technique [0002] The ballastless track slabs used in my country's high-speed railways are affected by factors such as line direction and terrain, and the same slab type also has different design specifications. For example, the CRTSIII ballastless track slab independently and vigorously promoted in my country, The design specifications include P5600, P4856, P4925, and P3710, among which the P5600 specification is the most widely used plate type, and the output (application volume) of other specifications is relatively small, but they are also indispensable. [0003] The current production method of pretensioning ballastless track slabs has gradually changed from pit matrix pedestal production to assembly line production with technological progress. However, due to th...

AI Technical Summary

Problems solved by technology

Solve the problem that the single circular flow production line in the prior art cannot produce track slabs of different specifications at the same time and the problem that the whole line must be stopped for maintenance and failure

At the same time, the present invention also solves the topographical constraints of the application environment of the current production line, and the position of each station can be set according to the actual situation.
