Tongue device for switches lying in the pavement

The innovation relates to a tongue device for lying in the pavement Switches, preferably made of grooved rails with a tongue bed that forms a flat surface.

Tongue devices for inserting vices form through the on the inside the tongue necessary for the demarcation of the pavement, narrow long boxes in which the tongues are only a few centimeters when moving knock out in the transverse direction.

With such tongue devices the elimination of the traffic is important dirt that has got in is a task that is as necessary as it is difficult. The pollution can vary depending on the local conditions be considerable and also contain coarse parts which, if they get between the tongue and stock rail, prevent the tongue from resting and thereby causing damage to the tongue device and even can lead to the derailment of the vehicles.

Attempts have been made in various ways for street grime to create a special space so that the relocation is not hindered.

So you have switches with a continuous tongue bed in the stop side the tongue attached a longitudinal groove, which, however, must have small dimensions, so that it has an insufficient effect. In the case of pavement switches for freight wagon traffic, instead of a plate-shaped

Tongue bed arrange individual sliding chairs, between which the dirt is can accumulate. Coarse dirt particles can also cause malfunctions here if they lie on the sliding chairs. They move in the lengthways direction not by itself. The larger dirt space allows somewhat longer time intervals between the individual cleanings, that However, this makes cleaning even more difficult.

The task, the solution of which the innovation has set itself, is To create receiving spaces for the dirt that can be cleaned in a simple and easy manner.

According to the innovation, the characteristic of the solution is seen in the fact that Tongue bed is provided primarily on its two longitudinal edges with deepened, continuously extending recesses in the longitudinal direction.

When moving the tongue pushes the dirt lying on the tongue bed into these deepened recesses. Because these recesses run continuously in the longitudinal direction of the tongue bed, their cleaning is .. particularly easy with a switch broom. Its longitudinal movement is no longer disturbed by transverse obstacles such as sliding chairs. To that To simplify cleaning even further, according to a further feature, the head of the counter rail is undercut on the side facing the tongue.

Analogously, this arrangement can also be used for broad-footed rails will. The idea of innovation is also used when the longitudinal recesses for the for the implementation of the retaining screws of the connected to the rails Tongue bed required piece are inclined or interrupted.

As an example of the subject of innovation, there is shown in the figures Tongue device of a grooved rail switch with articulated tongues selected. Show it

Fig. 1 the left half of the tongue device in plan view,

Fig. 2 the right half of the tongue device as a section at the level of Zungeribattes according to H-H of Fig. 4,

Fig. 3 shows the tongue device in cross section according to HI-HI of Fig. 1, 4 shows the tongue device in cross section according to IV-IV of FIG. 2.

Between a stock rail 1 and a counter rail 2 rests on brackets 2a, 3 a tongue bed 4 which serves as a guide for a tongue 5. The tongue bed 4 can of course also be designed in any other form. It has recesses 6 running in the longitudinal direction into which the When the tongue 5 is turned over, the dirt lying on the tongue bed 4 is pushed.

Fig. 3 clearly shows the free cross section of the innovation for the Recognize cleaning created space 7 with tongue 5 placed against the stock rail 1. The accessibility of this room 7 is increased by that the tongue 5 facing side 2b of the head 2c of the counter rail 2 is undercut.

While the recess 6 between the interruption 8 in the tongue bed for the tongue connection, not shown, and the pivot point 9 of the tongue 5 runs on both sides of the tongue bed 4, the remaining Part of the tongue bed 4 has a longitudinal recess 6 in the middle, as two lateral recesses at the narrowest "point Support of the tongue would affect.
