Description

the speed control unit of the uncoupling mechanism 20. The control circuit also includes an uncoupling sensor 22, the output of which is via the uncoupling start monitoring unit 11. It is connected to the input of the uncoupling signaling device 23, and the output of the uncoupling sensor 25 is connected to a similar uncoupling signaling device 24.

The operation of the device proceeds as follows.

Before the dissolution of the train begins, the uncoupling mechanism 1 occupies the extreme position closest to the hump of the hill on the overpass 2, outside the uncoupling of a single wagon. After that, information on the number of cars in the first trailer will go to the index b of the number of cars in the trailer, it will be duplicated on the scoreboard 5 of the price operator and entered into the block 8 for selecting the mode of movement of the release mechanism through the block 7 for recording the number of cars in the trailer. This unit provides reverse engine, the Operator from the control panel 9 includes a synchronization unit 14 and the release mechanism 1 moves to the point of start of the trip zone from i wagons. During the movement, the uncoupling start zone sensor 10 counts the number of pointers of 3 points of the uncoupling start zones. The marking of the flyover into the decoupling zones by indicators 3 and 4 was made on the basis of numerous experimental measurements. The coordinates of the release start zones are described by the equation

ZHi 11.8 9i, m,

ZH) is the coordinate of the start point of the trip zone, m, 1i is the number of aagons in the release.

The coordinates of the location of the 4 points of the end of the trip are described by the equation:

, 2 + 7i.M

At the time when the (I) th indicator is detected by the sensor 10 of the trip start zone, the block 8 for selecting the movement mode of the trip mechanism gives a command to turn on the electric brake control unit 12. Here, at a stopping distance of 1 brake from the i-ro indicator of the start of the disengagement zone, mechanism 1 stands until the operator sees the automatic coupler that needs to be disengaged. In this case, the operator, depending on the speed of movement of the train, decides at what point in time it is necessary to start the trip. It turns on, when it sees fit, the synchronization unit 14 and disables for the duration of the trip the outputs of the movement mode selection unit 8 of the trip mechanism.

It should be noted that the reverse of the engine 21 is performed by the reverse engine block 15 of the release mechanism immediately upon activation of the electric brake control unit 12. From the moment the operator turns on the synchronization unit 14, the uncoupling mechanism 1 accelerates to the composition speed. Synchronization is carried out by comparing the speeds measured by the speed meter

19 release mechanism and speed gauge 16 composition. To transmit signals about the composition speed to the synchronization unit 14, the interface module 17 and the detector 18 were used. At the output of the detector 18, like

5 at the output of the speed meter 19 of the trip mechanism, the voltage is directly proportional to the speed of each of these objects. The voltage from the speed gauge 19 is supplied to the synchronization unit 14 directly, and from the detector 18 through the voltage divider. In the initial state, the entire voltage from the detector 18 is divided by 2, i.e. the initial level at the output of the detector 18 is two times (at the same speed) higher

5 level at the output of the speed gauge 19 of the release mechanism.

If the operator needs to catch up with the automatic coupler, he, pressing the pedal, changes the division ratio from 2 to 1 (smoothly) and

0 block 14 synchronization provides surge auto coupler. Next, the operator releases the pedal and the synchronization unit 14 for the entire release time provides synchronous movement of the uncoupling mechanism 1 and composition

5 (automatic couplers). If the operator did not have time to complete the trip to the end of the release zone of i wagons, the sensor 25 of the end zone of the trip is activated and the end switch 25 of the end of the trip is activated

0 (already useless, since automatic couplings are extended) attempts to disconnect wagons.

If he performed this operation to the point Zcki. This presses the release end button on the control panel 9. By this

5, the number of wagons of the next release is entered into the block 8 of the movement mode selection of the release mechanism. The logic of this unit is such that a minimum of displacement of the release mechanism 1 is guaranteed

0 overpass 2. So, if the number of cars I of the first trailer is less than or equal to the number of cars j of the second trailer, then block 8, having received the end of trip signal, activates the electric brake control unit 12, makes a horizontal movement mechanism and takes the cab to point ZHj. Moreover, the speed of movement of the cab to the next tripping zone (ZHj) is directly proportional to the speed of movement of the train. Indeed, block 14 synchronization

compares the absolute values of the composition speed and the release mechanism without taking into account the direction of their movement. This ensures a timely exit to the beginning of the disengagement zone. After going beyond the point ZH | by the signal from the sensor 10 of the trip initiation zone, the cab stops and the engine of the horizontal movement mechanism is reversed. However, the operator does not have the right to proceed immediately with the trip, until the trip initiation indicator 23 is activated via the trip release sensor 22 through the trip start monitoring unit 11. The inclusion of this indicator confirms the separation of the previous release and gives permission to disengage the next.

In the case when the number of cars i of the previous trailer was greater than the number of cars of the trailer, which is to be divided, the algorithm of operation of block 8 changes. Unit 8, upon receipt of the trip completion signal, includes an electric brake control unit 12, and the trip unit motor 15 does not turn on. After complete braking of the release mechanism 1, if condition () is satisfied, the brakes are released, but the release mechanism remains at the same point where the previous trip was completed. Here, the operator waits for the automatic coupler approach to be disengaged. In the order described above, the operator ensures the synchronization of the movement of the release mechanism 1 with the train and, after the sensor 22 detects the separation of the i-car from the train from the train 22, it starts disengaging by the signal of the signaling device 23. However, he does not wait to follow point 7c. Having completed the trip early, the operator gives a command to end the trip. In block: 8, the number k of wagons in the next release is entered, and the cycle of the device is repeated.

After termination of the dissolution of the train, one-pajop takes the cab beyond the ZOK.S point, and for a small interval between the dissolution (parallel thrust), it may not remove power from the control circuit of the release mechanism and wait for the train of cars to arrive there. where he finished disengaging the previous composition.

As follows from the description of the operation of this device, the largest number of functions is performed by the unit 8 for selecting the mode of movement of the uncoupling mechanism. The block diagram is shown in figure 2

The trip mode selection unit & includes a reversible counter 26 connected to the first group

the inputs of the comparison circuit 27, the outputs of the unit 7 for recording the number of cars in the trailer are connected to the second corpus of the inputs of the circuit, three outputs of the comparison circuit (if you use the K561IP2 circuit, then they are all gr), corresponding to the situations,,, are connected to the inputs of the OR element 28 , the output of which through the differentiating circuit 29 is connected to the input S of the RS flip-flop 30, the direct output of which through the OR element 31 and the electronic key 32 is connected to the switching circuit of the electric brake control unit 12, the output (KJ) of the comparison circuit 27 is also connected to one input element And 33 to another the input of which through the threshold element 34 and the differentiating chain 35 is connected to the output of the detector of the speed meter 19 of the uncoupling mechanism, the output of the element 33 is connected to the input S of the RS flip-flop 36, the direct output of which is connected to the relay 37, one input of the OR 38 element and one the input of AND element 39, the output () of the comparison circuit 27 is also connected to the other input, and the output is connected. to one of the inputs of the OR element 40, the inverse output of the mentioned trigger is connected to one of the inputs of the OR element 41, the inputs R of the two mentioned triggers connected via diff The supply chain and diodes 43.44 to the output of the block 7 for recording the number of cars in the trailer, the inputs of the reversing counter 26 through contacts 37.1 of the relay 37 are connected to b (the sensor 10 of the trip initiation zone goes to the inactive inputs of two-input elements OR 31, 38, 40, 41 the outputs of the buttons (not shown in Figs. 1 and 2) of the operator panel are connected: respectively, the button for turning on the electric brake, movement towards the hump of the slide, reverse movement, turning on the synchronization unit (it is also a button for starting the trip).

The disengaging mechanism driving mode selection unit 8 operates as follows.

After the end of the release from i wagons, the operator presses the end release button, and a new number j is received from the unit 7 for recording the number of cars in the release to the comparison circuit. which is compared with the number i entered from the reverse counter 26. In this case, at one of the mentioned outputs (,,) of the comparison circuit 27, a high level signal is generated. Since the output of the combining circuit 27 through the OR element 28, regardless of the situation, an input of a high level pulse will arrive at the input 3 of the RS flip-flop 30 through the circuit 29. The trigger will go to state 1, correspondingly high level. The trigger will go into state 1, respectively, at the input of the OR element 31 and the electronic key 32, a high level signal will be generated. The electronic key 32 is opened and the power circuit of the electric brake control unit 12 is closed. 5, the braking of the release mechanism 1 begins. After the release device 1 is completely stopped at the output of the threshold element 34 connected to the output of the speedometer 19, a high level signal 10 appears which, through the differentiating circuit 35, acts on one input of the And 33 element, and also at the input R of the RS-flip-flop 30, which is switched to the O state, the electronic key 32 is closed, the trip mechanism 15 is released. If the location of the release mechanism 1 corresponds to the situation, then no action on the engine from the side of the block 8 of selecting the mode of movement of the release mechanism 20 occurs. The operator waits until the required automatic coupler approaches the release mechanism and, by pressing the release start button on the control panel 9, puts the release mechanism 25 into synchronous movement with the train. Otherwise, the circuit works if. In this case, the voltage of level 1 is supplied to the second input of the And 33 elements from the output (KJ) of the comparison circuit 27, respectively, a pulse will be generated at the output of the And 33 episode, which will trigger the trigger 36 to state 1. A high level signal from of the immediate output of the trigger 36, the relay 37 is turned on and, via the OR element 38, the direction of movement of the trip unit 1 is changed by the reverse of the block 15 of the release motor of the release mechanism 1. According to the high level signals from the output () of the comparison circuit 27 and from the direct output of the trigger 36, the M 40 circuit 39 forms a signal high level, which through the OR element 40 enters the enable input of the synchronization circuit 14. From this moment, the release mechanism 1 begins to move from the hump of the hill to the point ZHJ. 45 Since the relay 37 is energized, through the front contacts 37.1, pulses from the sensor 10 of the tripping start zone will be fed to the summing input of the reversible counter 26. When the follow-up 50 is used by mechanism 1, the contents of counter 26 will increase by one by each of the pointers 71H-Znn. At the moment when the release mechanism 1 passes by the pointer ZJH, the output signal () from

penits from 1 to O, at the output of the And 39 element, signal O appears, the synchronization unit 14 will be turned off. At the same time, a pulse of positive polarity from the output () through the OR element 28 and the differentiating circuit 29 will trigger the trigger 30 to state 1 and, accordingly, the electric brake control unit 12 will be turned on. The release mechanism 1 will be braked at a distance (Brake from point ZHj.,

Since the trip mechanism returns to the beginning of the ZHJ zone at a speed equal to the speed of the train, the operator cab is guaranteed to timely exit to the beginning of the trip zone.

Fig. 3 shows a synchronization circuit and a voltage divider, the operation of which is described above.

Fig. 4 shows a diagram of a sensor 10 of a tripping start zone (it is similar to a sensor of a tripping end zone). The sensor comprises a radiator 42 located on the same axis as the photodetector 43, which is connected through an amplifier 44 and a discriminator of duration 45 to the input of the pulse shaper 46. The output of the pulse shaper 46 is the output of the sensor 10 of the tripping start zone.

The operation of the sensor 10 proceeds as follows.

During the movement of the trip mechanism 1 between the emitter 42 and the photodetector, a continuous optical communication occurs, which is broken when moving through the point of start of the trip zone. At this point, the space between the emitter 42 and the photodetector 43 enters an opaque plate index 3 coordinates of the beginning of the trip. If the optical connection is broken, a duration discriminator 45 is detected by the signal of which the pulse shaper 46 is activated. The discriminator 45 is necessary to protect against short duration interference, and the pulse shaper ensures the stability of the output pulses of the sensor 10 regardless of weather conditions and the speed of the trip mechanism 1. The sensors 10 and 25 and their corresponding indicators 3 and 4 are spatially separated, which allows the use of identical sensor circuits without compromising the reliability of their operation.
