Background technology
The features such as high-speed railway has that road speed is high, rate of traffic flow is large, passenger's comfortableness requires high, maintenance work can only carry out in the finite time after stopping transport night, rail system directly bears train load, concern traffic safety, so the performance requirement of high-speed railway to rail system is higher.Non-fragment orbit has the features such as high stability, high ride and few maintenance due to it, be widely used in world in recent years various countries high-speed railway, wherein plate-type ballastless track is conventional a kind of classification of track, and the key technology of plate-type ballastless track is track plates and manufacturing process thereof.Plate-type ballastless track is of wide application, and mainly concentrates on the common gauge railway of non-extremely frigid zones at present.Along with the continuous expansion of plate-type ballastless track application, slab track will constantly be extended on the railway of extremely frigid zones and large gauge.
The track plates be laid on above railway bears DYNAMIC LOADING OF DRIVING TRAIN ON BRIDGES and environment temperature load, often because causing track plates to occur the phenomenon of crack or fracture by external force deformation, therefore causes unnecessary loss, meanwhile, safeguards also very inconvenient; Special in extremely frigid zones and large gauge railway location, day and night temperature is larger, and the large scale track plates being greater than standard gauge will bear higher temperature load.For this reason, in the Design and manufacture process of track plates, must to arranging reinforcing bar or steel strand wires or rod iron or steel wire in track plates, and to its Shi Hanzhang, reduce with this distortion that track plates causes by external force.In existing track plates production process, the stretching mode of employing, be the independent stretch-draw of each track plates, stretching force is uneven, and the track plates intensity of production is not high, and stretch-draw amount can not adjust flexibly.
Summary of the invention
The invention provides a kind of manufacture craft being suitable for the large gauge track plates of extremely frigid zones high-speed railway, solve prior art middle orbit plate production stretching force uneven, the track plates intensity of production is not high, the technical problem that stretch-draw amount can not adjust flexibly.
The object of the invention is to be achieved through the following technical solutions:
Extremely frigid zones winter, summer Temperature Difference Ratio comparatively large, the present invention can according to the size of the different external environment numerical controls adjustment pulling force of locality.
The invention provides a kind of manufacture craft being suitable for the large gauge track plates of extremely frigid zones high-speed railway, by railway plate die being put neat and fixing, longitudinal reinforcement and transverse steel are passed from described steel holding holes, and by nut, described longitudinal reinforcement is connected with longitudinal cylinder lever connecting rod and lateral connection pull bar respectively with described transverse steel, start and longitudinally promote oil cylinder and laterally promote oil cylinder, respectively stretch-draw is carried out to described longitudinal reinforcement and described transverse steel by longitudinal stretch-draw platform and transverse stretching platform, controlled by the stretch-draw amount of digital control platform to longitudinal stretch-draw platform and transverse stretching platform, to the region placing concrete between described railway plate die to form track plates.Invention increases longitudinal stretching mechanism, provide track plates intensity; Realize numerical control to control, can adjust the size of stretching force according to engineering specifications, adapt to local external environment, adaptability is stronger; Employing numerical control controls, and reduces labour intensity, improves operating efficiency; The track plates produced is not only applicable to ordinary temp area and the railway of conventional gauge, is more suitable for the large gauge high-speed railway that extremely frigid zones and gauge are 1520.
