Abstract

The invention relates to the management of industrial lifting and transport mechanisms and allows to increase the reliability of the device. To do this, it is equipped with a relay 14 controlling the actuator 2, a stopper and a time relay 15. When a downstream signal is received from the object, power is supplied to terminal 24. Relay 14 is turned on by its closing contact (LC) 14.1 in series. The serially connected LC 2.1 of the actuator 2 of the stopper and the break contact of the actuator 3 of the actuator 3 are moved up. At the same time, the ACL 14.2 of the relay 14 bridges the ACL of the manual control button 10 and the ACL 14.3-LC 15.2 of the relay 15. The actuators 2 and 3 are turned on. Starter 2 is powered on one side of the terminal 16, and on the other via ZK 14.1 button 7, RC button 10 and terminal 20. Starter 3 is powered from terminal 16 on one side via the ZK sensor 13 of the safety brake, PK 4.1 actuator 4 of the drive Down and on the other through ZK 14.2, button 9 and terminal 21. When the automatic stop circuit is opened, the power supply to terminals 20 and 21 is stopped, the starter 4 and relay 15 are turned off.

Description

The invention relates to controlling the transport of machinery and can be used to control the transport and lifting mechanisms, in particular to control the lift, moving along an inclined path by means of a winch and a cable in automatic mode.

The purpose of the invention is to increase reliability.

The drawing shows the electrical circuit of the device.

The device contains a safety brake actuator 1 with a closing contact 1.1, a stop 2 starter with a closing contact 2.1, a drive start Up 3c a closing contact 3.1 and a breaking contact 3.2 and 3.3, a drive 4 with a breaking contact 4.1 and a closing contact 4.2, manual control buttons 5-11, stopper position sensor 12, safety brake position sensor 13, stopper actuator control relay 14 with closing contacts 14.1-14.3, time relay 15 with closing contacts 15.1 and -15.2, communication terminals with the object 16-24, sensors 25 to the brake pad wear, warning lights 26 stop sensor signal lamprophyllite nN 27 gauge safety brake, two resistors 28 and 29.

The device works as follows.

From the object management system, terminals 16 and 20 are continuously supplied with power to the device, terminals 17 and 20 are energized through the object's emergency disconnecting circuits, terminals 20 and 21 are energized through automatic winch stopping circuits, and terminals 18 and 19 receive a signal engage safety brake. The starter 1 is turned on and powered through the closing contact 1.1, the contacts of the button 5 Stop, the contacts of the wear sensor 25 of the brake ring from terminal 17 on one side and terminal 16 on the other side.

The safety brake is released; the contacts of the sensor 13 are closed, the lift-up circuit has been set up or down. According to the cyclogram of the operation of the object, terminal 22 receives an Up signal, starter 3 is switched on and energized from terminal 16 through the closing

When the automatic stop circuit is opened, the power supply to the terminals 21 and 20 is stopped, the starter 3 is turned off, the lift stops lifting.

When a downstream signal is received from an object, power is supplied to terminal 24, relay H is turned on, and its circuit is closed. with a tactile contact 14.1, the serially connected closing contact 2.1 and the opening contact 3; 2 are bridged; at the same time the closing contact of button 10, the closing contact of button 10, and the closing contact at 14.3 - the closing contact 15.2. Starters 2 and 3 are turned on, 5. Moreover, starter 2 is powered from terminal 1 on one side and through the closing contact 14.1, button 7 contact, opening contact of the button 10 and terminal 20 on the other side, and starter 3 is powered from terminal 16 through the closing contact sensor 13 of position of safety brake, disconnecting contact of sensor 12 of position of stopper, disconnecting contact 4.1 of interlocking on one side and through closing contact 14.2, contact of button 9 and terminal 21 on the other side.

The lift is engaged on a climb, the winch drum is rotated at a certain angle, the stopper dog is released from squeezing and is disengaged. The opening contact of the sensor 12, the position of the stopper opens, the actuator 3 is turned off, the rise
