The device 39 is a sound command signal for the control of a lada I ,,, -, connected to phase C and through parallel-connected contacts of the relay 22, 24 - to y G lu compounds, which are connected in parallel via relay contacts 15 and .16 is coupled to node E eoedpneny. Sensors 5-8 are mounted on the l-dah. Reversing actuators and “positioning relays 1-4 l d are located in the power cabinet of starting equipment, relay 15, 16 direction (events, blocking relays 20

and 21, positional relays 22 and 24, and alarm relay 25 in the relay cabinet ld, and alarm lam-buds 26-34 on the control panels of the trainers and the lifting machine driver.5

The device works as follows.

In the normal position, when the tank is 1B, the bottom of the barrel, l and yes (the unloading area of the 1K1I is open, and l and zero 10 sites behind the Kryta, about which they signal the mountains of the light bulb 29 and 26, the circuit of which is closed through the closing relay contacts 4, I position ld. The latter are switched on through the contacts of the tS sensors and position 5. 15 Splitting contacts of the sensors 9-14 of the position of the bucket; in stolvoloko-1 zam closed and closed - open (see. Fig. 1 ).

The withdrawal of the tub from the barrel 20 turns on the reverser of the lifting mask, and through its closing contact 17 turns on the relay 15 pointing upwards. Upon reaching the bucket with a distance of L + 5.5 m to the bottom, the Apple switch switches the level sensor 25 14. The signal lamp 30 closes the circuit. Open l do Yaple through relay contacts 20, 1-6, relay sensor 14, 2, 1, 15 and the coil circuit of the positional relay 22 through the contacts of the sensor 12. Relay 22 is triggered and 30 switches on the audible signal of the device 39 through the contact 22 of the operator’s alert about the need to open the unit, receiving the command “Open 35 liter Du N pl using the button pestle (not shown) closes the circuit of section 35 of the magnetic actuator. Since l da da., Is open, the contact of relay 4 is closed, and the actuator is turned on, l yes 40 // z is opened. At the moment of loosening j contact l, the contact of sensor 5 is opened, the relay is turned off, and is broken. chain lam) kidney 26, the last goes out. When fully opened, de Yapl is turned on through a short-circuiting contact of the 6 r sensor: there are barely 2 liters. Through the contact of relay 2, the circuit of the light bulb 27, which lights up, signals that l da Yep. Is open. At the same time, the contact of the relay 2 is broken by the pep of the relay 50 22 and the light bulb 30. The switched-off relay 22 breaks the beep circuit. In this way, the command signal "Open l doo" is removed. In case of non-opening of the trap I ', and further raising of the bucket 55, sensor 13 switches over after 5 meters, and the coad approaches 5.5 meters, switches the i / i2 sensor, the contact of which 1 turns on the blocking relay 24. The relay 24 switches on emergency relay 25 l d, 60 contact of which is connected in series to the hoist safety relay circuit (not shown), protection circuit, and will stop with safety braking.fiS

The lamp 30 will continue to be lit, receiving power. According to the circuit of the contacts of the relay 20, 16, sensor 14, relay 2, 23, it signals the reason that led to the emergency stop of the lifting machine.

Having opened the door, you can continue lifting the tub.

At a distance of 5 m from the rising bucket to the ice, the Box switches the sensor 11 and closes the coil circuit of the locking relay 20, the contacts of which open the circuit of the actuator section 36, the signal circuit of the control locking loop at the moment of the bucket in the barrel. Shutting the hole / UE, during the passage of the bucket through it, is excluded until the bucket rises above the open lids for a distance of 1 m before switching the sensor 10, the contact of which will turn on the shut-off relay 21, the contacts of which bypass the open contact relay 20 in the circuit of the actuator section 36. At the same time, the light bulb 32 lights up, signaling that it is possible to shut off the traces of I „1. The control of the discharge drive's discharge is possible when the tub rises 1 m above it. This switches the sensor 9, the contact of which will close the circuit of the signal lamp 33, signaling the possibility of closing or opening the discharge pad site.

Before lowering the tub into the barrel, for example, with the LRP.1, the dumping of full-time and zero sites should be disclosed.

From the moment the bucket IB is lowered, the barrel closes the contact 18 of the reverser or the pin 19 (when the bucket is lowered in the dynamic braking mode), which turns the relay 16 downward. Contacts 18 and 19 are shunted by a circuit from series-connected contactors of relays 15 and 16, preventing the relay 16 from turning off at the time of transition from one operating mode of the hoist to the bucket and another (from reverser to dynamic or mechanical braking). As soon as the distance between the descending pail and the open unloading trap decreases and becomes less than 1 m, the floor sensor 9 switches and the RPL drive cannot be controlled by further descent of the bucket, the sensor 10 switches the relay 21 off and the latter deactivates the contact the circuit of the actuator section 36, thereby excluding the possibility of closing the nucleus junction during the passage through it.

When the bad will go through the loop, the sensor 11 will switch, the blocking relay 20 will be switched off by BOTH contacts will close the power supply circuit of section 36 of the position lock actuator l d.

After 0.5 m of movement of the tub down after the relay 20 is turned off, the sensor will switch.

12.B- as a result, immediately in “L10 reads the relay 24j, the switches of which will turn on the sound alarm device 39 and the warning lamp 31“ Zafatt l am I ,,.,. After closing the terminal, the circuit of the relay 24 is opened by the contacts of the relay, 2, and the relay is disconnected, thereby removing the command command 1

; signal from the device 39I lamp 31.

In the case of an unclosed ld y i .., when: the tub reaches the depth of the barrel, corresponding to the switching point of the sensor

13, the last switch is switched on and with -SHORTH contacts with the position relay 22. The switches of the relay 22 will turn on the relay 25, .y: the contacts of which will break the circuit of the emergency relay of the hoist machine. Pro; the safety braking will come on and the hoist will stop.

; Signal light 3-1 “Close the ludes will receive power through the circuit through the contacts of the relay 23, 1, 2, 15 and sensor 14, - signaling about the reason for the emergency stopping of the lifting tire 1ma1.
