Description

The usual telecommunications systems for cable cars use the pull rope, the opposite rope and the Carrying rope as signaling power lines, whereby mostly the pull rope and the opposite rope are not electrical from each other are separated, but form a single piece of the signaling circuit. For connecting the suspension rope to the signaling circuit of the car is a sliding contact or sliding on the suspension cable a contact role is required, soft to permanent disturbances, especially significant disturbing noises give cause in the telephone connection.

It is also known to electrically separate the pull rope from the opposite rope in the car and the telecommunication system to switch on in this separation point, whereby in the 'stations in signal currents from the pulling and opposite ropes with the help of contacts sliding (e.g. brushes) or rolling contacts (e.g. pulleys) on the ropes or rope sheaths). A completely undisturbed speaking and signaling is but under unfavorable circumstances, such as B. on icy ropes, on ropes with a thick layer of lubrication, not possible.

The Ultra-Kurzwelleri operation could 'probably without contact transitions between the ropes, wagons and Stations find use, but so far has never been used for signal transmission, mainly because for the cable car the wireless message transmission is only an additional facility the regulations were permitted.

The well-known conveyor cage telephony system with inductive coupling to the rope has as a result of Leads via the earthed supports and as a result of the difficulties in attaching the ring transformers on the ropes shown as not applicable to cable cars.

The 'telecommunication system according to the invention has the advantage that it uses technically simpler means no sliding or rolling contacts on a rope, so both parts of them are moved relative to each other, and therefore also under the aforementioned unfavorable circumstances the cables are properly routed.

In the case of cable cars, this is used as cables for the signaling circuit, opposite sides, Carrying ropes and, if necessary, auxiliary services according to the invention by combining the known measures achieved that on the one hand the pull rope or the pull ropes from the opposite rope or the Counter ropes or pull and counter ropes can be separated from one another at the connection points in the car are that each of the ropes forms a separate piece of the Meldelcitung and the telecommunications system of the Carriage (■ /, e.g. a telephone, pole reversing switch, power source) in the separation point between at least two Telecommunication system for cable cars

Walter Vogl ₁ Garmisch-Partenkirchen, and Dipl.-Ing. Dr. techn. Eduard Senn, Bad Godesberg, have been named as the inventor

Ropes is switched on, and that on the other hand in the stations for the power take-off from the ropes this in relation to relatively stationary contacts attached to the sheaves are used.

The invention is explained in more detail below with reference to the drawing in several exemplary embodiments.

1 shows a circuit diagram of a telecommunications system of the type customary up to now for comparison purposes;

Figs. 2, 3, 4 and 5 show various circuit diagrams of systems according to the invention.

In the conventional systems according to FIG. 1, the signaling circuit goes from the telecommunications system of the car, which consists, for example, of a telephone, a power source and a pole reversing switch, via the pull rope Z and the opposite rope G, which are conductively connected to one another and therefore a common one Form part of the signaling line, to contacts K, which are built into the sheaves and therefore rest relative to the rope, to the sliding contact on the traction sheave of the mountain station, to the signaling device M of the drive station and from there to the support cable T and via the contact roller R to system A. return.

1 system A1 of the valley station is connected in an analogous manner between the sliding contact S1 and the suspension cableT. In Fig. 2, which shows a system according to the invention, the same parts are provided with the same Be1 reference numerals. The difference, however, is that the pull rope Z and the opposite rope G are electrically isolated from each other at the connection point of the car. Furthermore, two auxiliary signal lines H1 and H 2 are provided as return lines, so that the signal circuit has no connection to earth From the signaling systems A, the car via the pull rope Z1, the acceptance contacts K, the sliding contact S1, the signaling relay M1, the auxiliary cable Hl to the sliding contact 51 and the acceptance contacts K1 and via the opposite G back to the systems A. The auxiliary cable H2 is used to connect the signaling system Al of the valley station, the circuit of which is closed via the contact parts and SI, the opposite cable G, the signaling system A and via the pull cable Z to the sliding contact 5 "and the auxiliary line K 2. The system according to FIG. 3 has the same structure as that according to FIG. 2, but here instead of the auxiliary cable H1 the support cable T is used as a return line between the signaling system M and the sliding contact IS-I of the valley station. In addition to the omission of an auxiliary rope, this has the advantage that contact (looping) of the opposing rope G and the supporting rope T does not result in any difficulty, because these two parts are conductively connected to one another in any case. The auxiliary rope H2 shown here is again used to connect the signaling system of the valley station. If one is not needed, this auxiliary rope is also omitted. In the system according to FIG. 4, further precautions are taken to keep the system ready for use, even if the pull rope comes into contact with the suspension rope or if the pull rope and counter rope come into conductive contact with one another. For this purpose, a changeover switch U1 is provided in the cabin system A, a changeover switch Ul in the mountain station and a changeover switch U 2 in the valley station, which allow the auxiliary cable H3 or the support cable T to be switched into the signaling circuit. In the position of these switches U and Ul drawn in full lines, the signaling circuit from A is closed via the pulling cable Z, signaling relay M1, supporting cable T and counter cable G. If there is contact between the tension cable Z and the suspension cable T, the switches U1 and U2 are switched to the position shown in dashed lines, whereby the auxiliary cable H 3 is switched on in the signaling circuit instead of the suspension cable. If a conclusion has occurred between the pull rope Z and the opposite rope G, the switch U is thrown, whereas U1 and U2 remain in the original position. The signaling circuit runs from system A via pull cable ZjSchleifkontaktS, signaling relay M, changeover switch Ul, support cable T, contact roller Rl, Unu switch U1 so that the opposite cable no longer acts as a separate cable of the signaling line, as it appears to be connected in parallel to the pull cable through the end . In the system according to FIG. 5, multiple changeover switches MU, MU1 and MU2 are provided in the stations and in the carriages, which allow different of the three connecting lines between the carriages and the stations to be used depending on the circumstances. "The changeover switch MU has two four contacts and the changeover switches MU1 and MU2 each have four additional contacts, which are labeled 1, 2, 3 and 4. The position 1 of the changeover switch corresponds to the normal position in which the pull rope Z, counter rope G and support rope T are switched on. Position 2 is used if the opposite rope is torn. The carriages are then connected to the drive station via the traction rope and carrying rope and to the opposite station via the auxiliary rope H. Position 3 is used if the traction rope is torn Carriages are then connected to the stations via counter rope, support rope and auxiliary rope. Position 4 is used for the case when the pull rope and the counter rope are conductively connected to one another, which corresponds to the case according to Fig. 1 or 4 with the switch Pull rope and a counter rope two or more such are used, these can gesc by electrical separation at the connection points as separate parts of the signaling circuits be held. By arranging suitable changeover switches, all incidents, such as rope breaks, earth faults, rope entanglements, etc., can be taken into account, whereby the individual ropes can be included in the reporting circuits either individually or also auxiliary ropes and the suspension rope.
