SU143839A1 - Device for remote control of the drive arrow - Google Patents

Description

There are known devices for remote control of the drive of a monorail track of an industrial production electric train, comprising a servo motor, a magnetic reversing starter, path switches, an electric lock and signal devices.

In order to reduce the number of wires, electrical interlocking of the drive control using one AC source in the proposed device, the line wire in series includes the winding of the power relay and two switches of the arrow drive wires, shunted through the contact of the blocking relay. The coils of the magnetic starter, the electric lock and the signal lamp are connected to the contacts of the path switch to each of the other two linear wires. To prevent the switch from moving while the electric train is on its way to one of the line wires parallel to the signal lamp, a blocking relay is connected through the track switch contacts to close the control relay circuit when the train leaves the track pin. In order to fix the needle in the translated position, the coil of the magnetic starter is connected to the electric lock lock parallel to the coil.

A schematic diagram of the drive control device of the arrow is shown in the drawing.

The device contains a reversible magnetic starter with two coils, q 2, step-up transformer, two AC relays 4 and 5, electrolock switches 6 and 7, signal lamps 8 to 9, as well as switches and connecting cable.

A magnetic starter, a relay 4, a transformer 3, a servomotor 10, solenoids of the lock switches 6 and 7 and two stop switches // and 72 are installed near the switch of the monorail track.

No. 1438392.

The arrow is controlled from the starting board, on which the signal lamps 8 and 9, the relay 5 and the switch 13 are located. In the right position of the switch 13, the power supply circuit of the relay 4 is interrupted. Contacts 14 of this relay are closed. Under the action of the voltage 24 and applied to the contact 15, the solenoid of the switch 6 and the coil 2 of the actuator are activated. The electric lock unlocks the arrow, and the engine 10 moves it until the arrow returns to the normal translated state. At the same time, the arrow presses the stop switch 12, which with its contacts opens the supply circuit of the solenoid switch 6 and the coils 2. The engine 10 stops and the electric lock locks the arrow in the transferred state. At the same time, a circuit is formed for the passage of current through the signal lamp 8, which signals the transfer of the arrow to the second path. To switch the arrow to the first path, it is necessary to transfer the switch 13 to the left position and at the same time close the contact 15. The contact 15 is closed only by the protrusion of the electric train. Therefore, the transfer of an arrow from one route to another can be carried out, provided that the electric train is at its loading (sending) point. When this condition is met, the relay 5 is released. By contacts 16 of this relay, the earth conductor 17 is supplied with a "ground." The relay 4 operates and by its contact 14 creates a circuit for the operation of the coil / magnetic starter and the solenoid of the switch 7..

Further operation of the device proceeds as described. A switch 18 is also located near the arrow, which is used only for adjustments and adjustments. During operation of the device, the switch is closed for access. In this position, the switch contacts connect the wire 17 to the relay coil 4.

The proposed device allows ensuring complete safety of the operation of a single-track monorail in two directions. The device was introduced in March 1961 at the Narofominsk weaving factory and showed good results in work. The introduction of this device allowed the carters to be freed from accompanying the electric train and from manually moving the track arrow directly to the arrow, thereby increasing labor productivity and facilitating the work of the carriers.
