Description

The contacts are relays 25 and 26, an anti-counter relay 32 with contacts 32.1-32.4, a time delay relay 33 with contacts 33.1-33.4, a control relay 34 with contacts 34.1-34.2, a switch control input unit 35, containing relay contacts , switch-on start-up unit 36, second repeater 37 with contacts 37.1-37.7, floor button station 38 with button 38.1, second power supply 39 connected to block 36, to another input of which switch dial 40 with contacts 40.1-40.3, arrow indicators 41 and 42 and pins 43 and 44, respectively, plus and inusovogo control switch position of the switch actuator. In addition, a resistor 45 and a capacitor 46 are connected in the relay circuit 32, a capacitor 47 is connected in the relay circuit 33, and a resistor 48 and a capacitor 49 are connected in the relay circuit 37.

The device works as follows.

In the initial state, the follow-up control relays 9, controlling the relays 34 and the time-control relays 33, are turned off, and the relays 12, 25. 26, 27, the repeaters 31, 37, and the relay 32 are energized. When entering the moving wheels 1 on the threads of the second branch, the valve 23 is shunted and the track relay 26 is opened, its contact 26.2 is disconnected, the relay 31 is de-energized. Contact 31.2 is opened with a slight deceleration (0.3s), the circuit is closed by contacts 31.1 and 26.3. commands (to influence block 36) on moving the arrow from the positive to the negative position. Relay 37, having sustained a deceleration of the order of 0.7 s, releases the measles and opens contact 37.6 in the control circuit until the BR rails completely free of the cordless rail line, and the short-term (up to 4c) loss of the train shunt does not lead to false control freely due to the oncoming switching on the windings of the repeater 37 and the circuit of the initial excitation of this relay through its normally open contact 37.7,

When the compound on the filament 20 enters the curvaceous motion and at the minus position of the arrow, the device works in the same way, the arrow is automatically shifted to the positive position, since the relay 25 bypasses and the relay 26 remains excited. The pointer 42 signals the position of the arrow.

When the anti-woolen movement is used, the driver uses the indication of the indicator 41. If the position of the arrow corresponds to the required route of the anti-woolen movement, the driver sets the track speed of the rail section 3.1 with the front wheels of the composition not lower than specified for this case (for example, more than 1 m / s), at which the arrow will not be translated, since it does not form a circuit to energize the relay 34. If, however, the needle needs to be transferred in the anti-woolen movement, the driver sets a reduced speed Vn (eg measures 1 m / s and below) movable along the rail

0 section 3.1 of a certain line (for example, 12.5 m). It is clear from the diagram that the relay 9 is energized at the moment when wheels 1 enter the section 3.1, limited by 4 m 5 joints, and is de-energized at the moment when the wheels enter the rail 5 threads 15 by joints 5 and 6 (see p. 27.2), speed of 1 m / s, the open state of contact 9.5 and the closed state of contact 9.2 for 12.5 s. Thanks to the charged capacitor capacitance 46 relays

0 32 after opening the contact 9.5 keeps its measles for a predetermined time determined by the parameters of elements 45 and 46 and the relay 32 itself. During this time through the contacts

323, 9 2, 37.4, 33.3 with some slowdown (see cm, capacitor 47 and the coils of the oppositely connected relay 33) attracts its measurability relay 33. Then a circuit is formed through contacts 12.1, 32.5, 33.4, 9.4 for supplying control relay 34. Relay 33 with a charged capacitor 37 capacitance holds the measles and the closing contact 33.4 for a specified time and after the opening of contact 32.3, the control command is dispensed, the shunt time of relay 26 (see contacts 43 and 34.2) is followed, followed by exposure through the unit 35 to block 36. At the same time, relay 33 eliminates the dangerous transfer of an arrow in antisocier Motion when the relay 32 loses its slowing properties on the release of the core (for example, when the capacitor 46 is broken by an excited and already self-contained) by contact 32 3 les 32) in all cases, the unacceptably high skoro5 motion STI composition not calculated for the received length of the guard predstrelochno- th section - of rails 15 between the tip of the arrow and Kami joints 5 and 6. In the above-mentioned failure, irrespective of i and speedy

0 movement of the composition, with the excitation of the relay 9 and the opening of the contact 9.5 at the moment when the wheels 1 enter the section 3.1, the relay 32 immediately releases its measles and opens the contact 32.3, and the relay

33 stops unexcited, excluding the 5 excitation of the relay 34 and, consequently,

transfer arrow with emergency consequences.

The greatest positive effect is provided by the claimed device for those arrows, which are often used in

corner races, because after a half-flight of stretching the composition in the direction of movement for joints 5 and b and the complete release of the switch section of the aerodynamic rail slot, a stop is always required, ensuring a reduction in speed to the above speed and lower, automatic translation of the arrow and the subsequent counter movement in a half-flight of abasement, With such maneuvers, the driver interacts intensively with the compiler and should not be distracted by complex manipulations to enter commands for translating arrows pressing a large number of buttons locomotive remote proxy radioupravl arrows. The inventive device improves traffic safety, occupational safety, and accelerates maneuvers.

The ability to automate the process of converting an arrow using the inventive device without using complex telecontrol channel equipment (for example, DRA or ARSP equipment) increases reliability and reduces metal consumption, simplifies implementation and maintenance, and contributes to obtaining an annual economic effect from putting this device into operation about 1000 rub. on one turnout. The inventive device provides reliable control of the non-exceeding of the set speed of approaching the composition with the arrow in the opposite hair movement,
