Description

Switching regulator track switch

The utility model belongs to the special equipment in the trackage, particularly a kind of high accuracy, long-life, the multifunction switch formula track switch that can resist driving snow, dust storm and any other foreign matter.

Existing track switch, tongue need be to the closely connected design feature of stock rail when switching the rails, and running into big wind and snow, dust storm or other foreign matters influences when closely connected, and track switch can't be worked.Secondly, central point at railway frog must be reserved, 45 millimeters gaps that the wheel rim of buying car in installments passes through, make the rail of frog centre leading portion cut the lotus area and reduce (even present state-of-the-art track switch, between the tongue and stock rail of railway frog work, still have wide about 10 a millimeters load rail level not) not wear-resisting, vibrations are big, influenced the raising of the speed of a motor vehicle.

The purpose of this utility model provides a kind of high accuracy, long-life, can resist the switching regulator track switch of driving snow, big dust storm and any other external foreign matter.

The utility model is a kind of switching regulator track switch, the coupling part that it is made up of turn-out track part, railway frog, two straight rails and two bent lend rails and handle and select the switch machine of rail displacement to be formed.It is characterized in that, single selection rail of forming two selection rails of turn-out track part and forming railway frog respectively with common rail tie point be axle, two selection rails or single other end of selecting rail are synchronously selected to dock with two straight rails that continue or two bent lend rails (single rail of selecting is and a straight rail or a bent lend rail) respectively under the driving of switch machine.Like this, just can realize being divided into two circuits from bar line dew, select rail under the driving of switch machine as if two, select to dock with two straight line rails or with two bent lend rails on the right side of two bent lend rails on the left side of straight line rail or straight line rail respectively, same point at a railway track can be divided into three rail tracks, and promptly switching regulator track switch two select rail to be equivalent to DPTT double-pole triple throw switch in the circuit.

The utility model has the following advantages with existing track switch comparing:

1. because the two rails (replacing original tongue) that select of the utility model have adopted the selection of the DPDT working method that integrates with.It has eliminated the gap for switching the rails and reserving between tongue and stock rail.Like this, accumulated snow, dust storm, foreign matter have not just had the place to stay.It has the driving snow of resisting, the function of dust storm and other any foreign matters.

2. railway frog has also changed the design that original two rails intersect.Because two rails intersect, must reserve the gap that supplies the rail edge to pass through of 45 mm wides at frog centre.The rail that makes this Duan Yueyou be no less than 700 millimeters long effectively cuts the lotus area, reduces to not enough normal rail and cuts 1/3rd of lotus face, and wearing and tearing are accelerated, and very fast rail cover injustice has a strong impact on the raising of the speed of a motor vehicle.Present state-of-the-art railway frog design though changed the design scheme that two rails intersect, has been adopted the working method of original point tongue.Should this design than original design tangible progress be arranged, but its universal succession of shortcoming of tongue design got off, these shortcomings are:

1) owing to the needs that switch the rails, tongue always moves around between two stock rails, and is closely connected as tongue and B line, then will leave about 100 millimeters of C line.When wind and snow weather, when having filled up accumulated snow or other foreign matters in this gap, She Ji track switch can't be worked like this.

2) when tongue and stock rail are closely connected, the slit of one 10 mm wide is left in the centre can not load, has reduced the payload area wearing and tearing of this section rail and accelerated.

3) top of tongue can not be accomplished as blade sharply, and wheel still has vibrations through the tongue top time.Thereby influence the raising of the speed of a motor vehicle.

The rail that singly selects of the present utility model docks with the rail that continues.Adopt hilted broadsword alternative working method.The rail payload area that makes whole track switch part is with normally rail is the same, thus the life-span of track switch improve greatly, as broad as long with common rail.

3. no matter be twoly to select rail or singly select rail, all be mounted on the track switch pedestal, make the iron sleeper to the pedestal 495 millimeters of continuing, press special-shaped pressing plate, with the bolton of 4 M24 with pair select rail to dock.That such structure has realized is moving, the high stable between the quiet rail, and high-precision butt joint can be thought for the raising of the speed of a motor vehicle, track switch is without limits.

4. existing switch structure, in same point, a circuit can only be divided into two circuits, and the utility model can be broken through this-restriction.If desired, in same point, a circuit can be divided into three-line, and the two of this moment select rail will be designed to the form of DPTT double-pole triple throw.

The utility model is described in further detail below in conjunction with accompanying drawing.
