Description

In the proposed device, the warning of oncoming traffic of tramcars in adjacent lines in separate sections of the tramway is achieved by the fact that the oncoming carriage is deprived of current. This is achieved, according to the invention, by the fact that the car entering the site, mechanically interacting with the device supporting the contact wire of the adjacent track, removes that from the current receiver of the carriage located on this path.

In FIG. 1, 2, 3 depict (from three sides) schematically the proposed device when driving cars on the right track; FIG. 4, 5 and 6 is the same when driving on the left path; FIG. 7 - top view of the device; FIG. 8-part of the device, which operates when the car enters the area: FIG. 9-part, acting when leaving it from the site.

At both ends of the section above the contact working wire is installed but one equal-armed lever p and p. The upper ends with and from these levers are connected with steel wire, and between

220

the lower ends of the k and the nut are an ordinary bronze contact wire.

The ends of the contact wire are isolated from the levers p and /) -. When the arms p and p are in a vertical position, the contact wire is flush with the adjacent segments of the contact wire.

When removing the levers p up-from the vertical position, for example, turning them to the left, the wires connecting them are raised, and turning them back down. Returning to their original position, these wires do not change their tension or sag.

As mentioned above, the points of attachment of the contact wire to the levers are insulated and for the electrical connection of it to the adjacent segments of the contact wire on both sides serve short flexible insulated wires that allow displacement of the contact wire l and k.

The levers p and p are mounted on horizontal axes fl and e-, rotating in stationary axles and, and y. The described device is installed separately over each of the two paths of the site so that the axes in the left and the left paths go beyond the middle of the right way, as well as the axis of the right way, beyond the middle of the left. The first ones in the direction of movement at the entrance to the section of the axis in and in (external) by special elongated rods l (Fig. 8); At the exit from the site, the first in the direction of movement of the axis s, s (internal) are provided with shorter rods (Fig. 9). The rod n is connected by a cable m with a separate rod u, similar in position and action to the rod i; the point of rotation of the lever u is located above the lower end of the lever p. The carriage is provided, as usual, with a rope for transferring the roller, having some kind of retention device, which is not. allows the roller to be lifted up higher, rocks: eat, .1 inch, over-contact wire; therefore, if the latter is higher by an inch by a roller by 2–3, the current supply to the car’s electric motors will stop and the carriage will stop,

A bracket 3 is installed on the roof of the car to grip and rotate the rods l and p.

The car moving along the right track, having approached the first axis s, rotates the rod 3 with the bracket, as a result of which the axis s, together with the lever / 0 fixed on it, rotates; the latter raises the contact wire of the left track, which results in the automatic stopping of the oncoming track of the left track. Passing the car along the right track, the same clamp 3 captures the rod u connected by a cable with a b-rod sitting on the axis, which by turning this axis lowers the contact wire to the working position; the latter again rests on the roller on the left on the left track of the car, which receives, therefore, the opportunity to move to the site.

The device is intended by the applicant i primarily for installation on bridges, | on which the simultaneous finding | Two wagons on the same farm are not allowed. At the same time, it, on the instructions of the customer, has the following advantages: 1) the operating current with a voltage of about 500 V is not interrupted in the contact wire, as a result of which the use of special devices to protect against a voltage arc is redundant; 2) on the car, in addition to the simplest adjustment for limiting the lifting of the roller (for example, a hook held by a ring) and simple brackets located on its roof, is not required; 3) all devices are placed at a height that does not interfere with movement along the web of the bridge; 4) the presence of the strongest parts of the trusses on the bulls, where the opposing cars intersect, and the presence of connections between the two trusses of the bridge — makes it easy to stop the whole device and fix the ends of the adjacent linear contact wires; 5) it is possible to arrange the crossing of cars on many bulls, i.e. to increase throughput while maintaining the principle of having one car per flight.

The subject matter of the invention.

A device for preventing the possibility of oncoming traffic of tram cars on adjacent lines to separate sections of a double track in which a car entering the enclosed section on the one hand deprives the electric car of the oncoming car, in that the contact wires of both lines in this section are connected their displacement by flexible conductors with adjacent segments of contact wire and fastened with levers located at the ends of the section, connected by bars with each other and mounted on rotary horizontal Axis, in turn, provided with elongated rods that can interact with the protruding part on the car, with the aim of entering the section of the car turned the corresponding horizontal axis and, thus, removed the contact wire of the adjacent path from the interaction with the current collector luck on this carriage way. : Bip§ ||. „1-4 1 | - fiJi. | 1 f ,. jfellbt FIPO, a.-ilt ™ rY “ri-. . p | j ;;; jijMj - S ± z ±. -; ..-.: ...- igz
