Abstract
The utility model aims at conducting improvement design on the existing line turnouts so as to optimize products and promote the combination property of the turnouts. The turnout switch comprises a stock rail and a point rail, wherein the point rail leans against on the stock rail. The turnout switch is characterized in that a working edge at one side of the top end of the point rail contacted with the stock rail is an inclined plane, and the corresponding part of the stock rail is also an inclined plane. In the utility model, the original point attaching type point rail is changed into the point hiding type point rail, so that the tip of the point rail is hidden in the working edge of the stock rail, thus protecting the tip from being damaged by the rolling of wheels, being capable of reducing the abrasion on the tip of the point rail, and leading the point rail to keep good vertical stability under dynamic load function. After the improvement, the wear-resisting property of the point rail is improved, the service life of the point rail is prolonged, and the driving safety is guaranteed.
Description
Technical field
The utility model belongs to the improvement of railroad track technical field, particularly railway switch.
Background technology
Track switch is the capital equipment of track traffic.The height of track switch combination property directly influences safety, speed, capacity of driving etc.50kg/m7 number serial track switch is used for industrial and mining enterprises more, and its operation characteristic is: low speed, heavy duty, operation are frequent.This track switch in use, rail spare abrasion are serious, the maintenance work amount is big, application life is short.The problem of track switch existence at present: 1, the most advanced and sophisticated abrasion of curved switch are tight; 2, the vertical jumping phenomena of tongue takes place easily.
Summary of the invention
The utility model purpose is that existing row track switch is improved design, to optimize product, promotes the combination property of track switch.
Specifically, turnout switch comprises stock rail and tongue, and tongue is resisted against on the stock rail, and the top of tongue contacts a side with stock rail working edge is the inclined plane, and the stock rail corresponding position also is the inclined-plane.
The utility model changes original point end tongue into the point-hiding tongue, and the point of switch is ensconced in the stock rail working edge, is not run over and injure by wheel to protect the tip, can reduce point of switch abrasion, and make tongue keep good vertical stability under the dynamic load effect.After improving like this, can improve the anti-wear performance of tongue, prolong the application life of tongue, guarantee traffic safety.
Description of drawings
Figure is the utility model structural representation.
The specific embodiment
As shown in the figure, turnout switch comprises stock rail 2 and tongue 1, and tongue 1 is resisted against on the stock rail 2, and the top of tongue 1 contacts a side with stock rail 2 working edge is the inclined plane, and stock rail 2 corresponding positions also are the inclined-plane.Beginning to hide point from tongue 3mm section, is 3mm at most advanced and sophisticated depth of recess, and the processing gradient of tongue working edge adopts now generally 1: 4 preferably gradient of the wheel track of approval coupling, and the wheel and the coupling of rail are tended to be reasonable more.
Claims (2)
1. turnout switch comprises stock rail (2) and tongue (1), and tongue (1) is resisted against on the stock rail (2), and the top that it is characterized in that tongue (1) contacts a side with stock rail (2) working edge is the inclined plane, and stock rail (2) corresponding position also is the inclined-plane.
2. turnout switch according to claim 1 is characterized in that the processing gradient of tongue (1) working edge adopts 1: 4 preferably gradient of wheel track coupling.
