Flexible flow production line producing ballastless track slab through pre-tensioning method

Abstract

The invention provides a flexible flow production line producing ballastless track slab through a pre-tensioning method. On the basis of an existing annular production rail, an outer rail, an inner rail, an intersected rail and other auxiliary rails are additionally arranged; the double-channel double-station design is adopted, the rapid response capacity in production is improved and optimized, and devices can be standby or can be used. Multiple specifications of ballastless track slab dies are compatible with the flexible flow production line and can jointly operate on the same line to produce the track slabs. Besides, two specifications of dies can be used for production on the same line at the same time, so that the device utilization rate is improved, and the equipment investment is reduced. A central control room is used for intelligently managing and controlling automatic devices, a flexible technological process is adopted, so that the operation capacity of the production line can be adjusted, and the flexible flow production line is higher in flexibility. Due to the facts that the double-station design is adopted and the number of steam-maintaining modules (steam-maintaining rooms) can be increased and reduced, the yield of the tract slabs can be flexibly adjusted to be matched with the progress of a 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.
