DE559537C - Turntable with several tracks - Google Patents

Description

The track curves in connection are used to change the direction of the track vehicles with switches. At points of limited space, especially where branches to the right and left of the Main track are required and the normal turnouts because of their linear expansion cannot find a place, one uses the turntables. This device for Change of direction has the disadvantage compared to the use of points that during there is an interruption in traffic after the change; there is no through traffic. A change of direction in through traffic can be made possible by curves arranged outside the turntable will. In this case the track of the turntable only forms the connection of the curves to change direction, and 20. The advantage of installing the turntable as a length reduction is eliminated.

To remedy this disadvantage of the normal turntable, the present inventive concept serves in such a way that in addition to the straight, simple or arbitrarily intersecting main tracks on the turntable track curves are arranged, which are with the straight turntable main track in a certain geometric dependency. The following figures explain the present inventive concept.

Fig. Ι shows a turntable with a simple straight track,

Fig. 2 one with a track crossing at right angles. ³ ^

Fig. 3 shows a turntable with a track crossing at an oblique angle.

Fig. 4 shows a turntable with a simple track and a built-in curve next to it, whose tangent points of one end at 4 " Turntable circumference lies, with deflection tongues for changing direction, while the direction the tangent of the other end of the curve runs through the center of the turntable.

Fig. 5 shows the same track diagram, but the beginning of the curve is outside the circumference of the turntable and deflection tongues are also arranged to change direction.

Fig. 6 shows the same picture of the crossing straight tracks according to Fig. 3 with 5 " built-in curve according to Fig. 4.

Fig. 7, 8 and 9 are identical to Fig. 6 with rotation of the track situation under different Angles.

Fig. 10 shows the arrangement of Fig. 6 in a somewhat clearer form in relation to the Arrangement of the crossing and connecting curved rails.

Fig. 11 shows the same arrangement in a simplified manner Form omitting part of the full circular plate of the turntable and by shortening individual runways.

As mentioned, with normal turntables according to Fig. 1, 2 and 3, through traffic in a deflecting direction from the main track α of Fig. 1 is not possible. the

Turntable must be turned on track &; longer car trains have to be subdivided and turned off individually. Passage and diversionary traffic through curves adjoining the turntable is possible, but, as Fig. Ι track ad shows, the advantage of the shorter path length of the diversion through the turntable is lost. Even with straight lines that intersect at an acute angle (Fig. 3) from track to track /, other through traffic is not possible without rotating the disc. The vehicles must be turned off individually to change direction.

According to the present inventive concept, a curve of any radius is built into the turntable next to the straight track, through which the geometric position of the deflection direction is determined (see Fig. 4). Continuous diversion traffic to b can now take place from the straight main track α over the curve. In order to achieve tangential entry into the adjoining track b (Fig. 4), it is necessary that the center line of the tangent directions b of the curve ends at a ¹ and b run through the pivot point of the turntable. If straight through traffic is to take place via junction b (Fig. 4) through the center of the turntable, then under, / £. α, starting tangentially at track b , install a straight line bc (Fig. 6). Turning the disc by 180 ° (Fig. 7) then has the advantage that the direction of the curve branching off from right branching a ^l -b (Fig. 6) to left branching ca (Fig. 7) for the passing traffic changes without the expansion the track system is enlarged.

With further rotation of the disc in the version according to Fig. 6 or 7, it multiplies the number of possibilities for through traffic (see Fig. 8 and 9, turn around i8o ° dotted).

To make things easier, especially for narrow-gauge track systems, the turntable can be designed as a climbing frame. The result is the well-known climbing turntable, but with multiple straight trunk tracks and curved branch tracks, for which the new inventive concept can be used in practice. The embodiment of such a device is detailed in FIG. The device, which is designed as a climbing frame, now makes it possible to save parts of the turntable disk by leaving out parts of the straight track sections and connecting them as before with climbing tongues a, b, c, d, e, f, g, h (Fig . 11) is formed. By turning around the center point / (which is the point of intersection of the tangent center line), right and left branches can again be made in any direction, as in Fig. 6 and 7. In this case, only two deflection tongues k and / (Fig. 11) are necessary, whereby . the transition from straight line to curve only requires a change of the deflection tongues k or I without rotating the system.
