Description

Spring rocking bar

Technical field

The present invention relates to a kind of device of position of the tongue (Zungenschiene) that is fixed for rail switch (Gleisweiche), it is so-called spring rocking bar (Federwippe), this spring rocking bar is arranged between the track pad (Schienenunterlagsplatte) being fixed on rail sleeper, and by means of this spring rocking bar by tongue in the state reclining, press on the one hand stock rail (Backenschiene) or bracing frame (St ü tzknagge) and on the other hand away from state in pushing or be held in the minimum spacing that is in circumscribed with respect to stock rail.

This device comprises slide bar (Schieberstange) and the Connection Element assembly being arranged between tongue, and this Connection Element arrangement of components realizes the switching of level between slide bar and spring energy storage device (Federspeicher) and the therefore situation in the main motion plane of the level of the jointed gear unit so obtaining.

Background technology

Especially in file WO 97/47813, JP 2 906 477, UK 154 416, EP 01765229 and EP 1185449, absolutely proved the spring rocking bar flatly working of different structure typess.Known device makes it possible to tongue to be pressed in the state reclining to bracing frame or spacer block (Distanzblock), be pressed in stock rail place and/or away from state between stock rail and tongue, guarantee the minimum spacing of circumscribed.

In track switch, tongue abuts in ideally stock rail place and abut in bracing frame or spacer block place in the root area (Wurzelbereich) of track switch in closed state in the anterior region of switching device (Zungenvorrichtung).After longer operation is used, after repeatedly crossing tongue with full wheel-borne load (Radlast) in root area, the shape predetermined or prebuckling of tongue changes on track longitudinal direction.This alteration of form causes tongue in root area, in closed state, no longer to cling to bracing frame place.When crossing, this state can cause obvious wearing and tearing on the sliding surface of sliding bed (Gleitstuhl) or track pad because tongue in undesirable mode only because the lateral force of the wheel crossing clings to bracing frame place.At this, due to the vertical power additionally working of the wheel by crossing, at tongue foot downside (Zungenfu β unterseite) and between the bearing surface at sliding bed place or the sliding surface of corresponding track pad, there is obvious frictional force.

But tongue away from state in must between stock rail and tongue, guarantee minimum spacing, to avoid the inner face of wheel and contacting of tongue.Yet, due to tongue distortion and/or frictional force in a longitudinal direction, in coming from the device of prior art, no longer can realize enduringly this minimum spacing.

Summary of the invention

The object of the invention is to now so improve the reliable function that known spring rocking bar makes the structure space that needs are very little on the one hand and even also guarantee enduringly on the other hand spring rocking bar when using track switch very longways.

This object realizes by means of a kind of device (it comprises the feature of claim 1) in meaning according to the present invention.Favourable design scheme of the present invention limits in the dependent claims.

The present invention relates to a kind of device flatly working, comprising: combination static and dynamic swivel bearing, supporting is connected to each other by Connection Element; And the preferred helical spring of at least one spring energy storage device and the general slide bar for two tongues are moved.In meaning according to the present invention, the tongue that slide bar is configured to single-piece and joining rails track switch like this makes the preferred synchronous motion that realizes tongue in rail switch.At this, such swivel bearing is interpreted as to static swivel bearing, its position of rotation position is designed regularly in Connection Element assembly.Correspondingly, dynamic swivel bearing is this supporting, its point of rotation position may change during the transfer process of rail switch, therefore tongue from the state that reclines to away from moving period of state between and again between return period the inside at Connection Element assembly change.

Device according to the present invention makes can realize significantly narrower structure with respect to traditional solution, because traditional solution or use are for making the slide bar separating of tongue motion and/or using dual toggle to connect (Knieglenk).Yet these two kinds of solutions cause larger structure space and bring such consequence, the element of device so extend into degree in the tie spacing (Schwellenfach) of rail switch and makes unhinderedly to clog sleeper.

In a kind of preferred design form of the present invention, Connection Element assembly comprises lucky two static swivel bearings and lucky two dynamic swivel bearings, by means of its not only can be in the state reclining and also can away from state in guarantee reliably the position of tongue.A kind of Connection Element assembly is provided, even if it guarantees on the one hand, the lasting use of rail switch makes tongue abut in stock rail place or abuts in one or more spacer blocks place, and guarantee on the other hand to maintain the minimum spacing of tongue and stock rail, with avoid away from stationary state in the contacting of the wheel that crosses and tongue.This utilizes the structural member of especially little quantity and therefore saves especially space and realize reliably.

If Connection Element assembly have other all element of proper what a curved bar and Connection Element assembly be configured to substantially straight, yet be at least configured to without outstanding angle, this is especially preferred in this connection.Accordingly, provide a kind of device, its conversion from a stationary state to next stationary state can realize especially simply and with especially little inefficacy danger.

Be equally particularly preferably Connection Element assembly, itself and spring energy storage device so interaction make the dead point of crossing spring energy storage device when handoff path track switch.This realizes especially thus, for example, from the first stationary state (tongue abuts in the state of stock rail) for example, to the handoff procedure of the second stationary state (tongue is away from the state of stock rail), the power that overcomes the spring energy storage device of preferred pretension in the first motion path of slide bar realizes the motion of Connection Element assembly, and in intermediateness, pass through dead point, therefore pass through the point of the maximum compression of spring energy storage device, and the support that finally utilizes spring energy storage device in stationary state to be arrived realizes the remaining motion of slide bar, therefore utilize simple especially device to create a kind of device, it can keep desirable two kinds of stationary states reliably by means of unique spring energy storage device.

Thus, if Connection Element assembly is fixed between the tongue of rail switch on the sleeper of track, this is preferred equally.Guarantee accordingly according to the lasting and mobile place, desirable place that rests in rail switch reliably of device of the present invention.Avoid one according to the single elements relative of device of the present invention in tongue or stock rail to change its position limiting in advance simultaneously.
