SU40817A1 - Automatic device for impact from the track to the moving train - Google Patents

Description

Typically, in devices for acting from a path on a moving train, when the track signal is set to the open position, the track contours depending on the track signal do not work. The effect of the track contour on the train occurs only when the train passes a signal in the closed position.

Preparation of the route is usually scheduled in advance, and therefore it is rarely the case that trains approach a closed signal. Therefore, devices from the track to the train, mainly the paths of the track current, during normal operation are only occasionally tested for their correct operation. In terms of security, this is a flaw, the elimination of which constitutes the essence of the present invention. This is achieved as follows. At a sufficiently close distance from each other, there are two contours of the traveling current, which serve to send a signal to passing locomotives, of which only one in its action is from the corresponding traveling signal.

With an open signal, both respective path loops jointly operate and, therefore, do not affect the train. With a sequential arrangement of ground current circuits, you can use the time between the passage through one circuit to travel through the next to give a special signal of free passage, which, therefore, can act only briefly.

When the track signal is closed, one of the two paths of the track current becomes inactive, and as a result, the other circuit drives the said locomotive device.

The device described above can be used with any device for influencing the train, for example, with any induction device with constant or alternating current, with or without resonance, as well as with electromechanical and purely mechanical devices. The latter, however, are less economical than inductive devices, since the cost of a signal path is small compared to the cost of a cable.

controlled path loop with a path signal.

In FIG. 1 shows the electric circuit of the device in use when 1 and inductive coupling of the resonating circuits of alternating current is applied; FIG. 2 - a detail of the inclusion of some of its parts.

FIG. 1 O designates an alternator, S is a signal relay that triggers when the primary resonance current changes when a track device is applied through communication coils L and Z, 2 paths one after another, two paths are located at a short distance from each other , of which only one, the signal position is switched by means of a key / 1 L controlled by a main signal.

FIG. Figure 2 shows a circuit for switching a relay, through which alternate effects of both track circuits can be obtained, on a train loop causing a signal when the track signal is open, and a single stroke on the train loop activating the brake when the signal is closed. Under the influence of the path circuit, the relay S at the moment loses its excitement and releases its measles, which turns on the electromagnet D. The latter controls the step commutator, the rotating contacts of which are moved along fixed contacts, some of which are idle and others are interconnected and serve to control further electrical processes.

When the track signal is open, due to the alternate effect of both track loops on the train loop, the step switch is moved two steps. With a closed track signal, only one track loop acts on a train loop, as a result of which the same switch moves one step. In the rest position, the rotating contact of the switch is at the idle contact. Therefore, if only one current impulse gets into the magnet D, then the rotary contact d, nepshift one step, hits the brake contact. If this turning

the contact will stop for a long time at the indicated fixed contact, i.e., if a second travel impulse does not immediately follow, the brake valve Br will come into effect. After the valve is opened and the brake is applied, the electromagnet D can receive a subsequent current pulse through a special switch Lg and a rotating contact d, after which the rotating contacts of the step switch are re-installed on the idle contacts and the switch-on circuit of the relay will again be ready for action.

When the rotating contact of the switch passes the brake contacts when the signal is open, the rotating contact d will turn on the relay V, the measles v of which will close the lamp circuit Z, indicating that the signal is in the open position. This lamp, therefore, lights up briefly with the trip signal open and indicates that all the gear units of the engine and the track are in order.

Setting the rotary contacts of the switch to the idle contacts after activating the brakes via the switch Lg can, of course, be carried out independently.

The described method of activating the brake valve Br with a closed path signal, as well as the inclusion of an optical signal, for example, a lamp Z with an open path signal, does not constitute the essence of the invention and are presented as an example. The brake and signal can be activated in any other way, for example, from direct current, etc.

The subject of the patent.

A device for acting from a track onto a moving train, characterized in that on the track, at a short distance one behind the other, there are two paths of the current, serving to give a signal to passing locomotives, one of which depends on the corresponding track signal with the intention that with the open way: a signal, thanks

to the alternate action of both track circuits on the train loop, the step switch was moved two steps, and when the track signal was closed, due to the action of only one track loop on the train loop, the same switch moved one step.
