Abstract

The invention relates to devices for controlling the doors with electric motors and can be used to control the doors of a double-leaf swing gate. The aim of the invention is to improve the usability of the device. When the pushbutton switch 14 is pressed and its contact is closed, the contactor 6 opens the first flap, which, when turned on, closes its contacts 6.4, supplies power to the electric motor 4, contacts 6.1 blocks itself and contactor 8 opens the second flap to turn on. At the same time, the electric drive consisting of the electric motor 4, kinematically connected with the gearbox, through the system of levers begins to open the first flap, after the opening of which the limit switch 11 is released and the contactor 8 opens the second flap and opens its contact. In turn, the contactor 8 opens the second flap, turning on, supplies power to the electric motor 5, which is also switched on by means of res $ (L

Duktor and leverage begins to open the second flap. When the first leaf and the second leaf are fully opened, I influence the limit switches 10 and 12, respectively, opens contactors 6 and 8, which, in turn, turn off the electric motors 4 and 5. The gate closes as described and differs only in that when you press The pushbutton switch 15 and turning on the contactors 7 and 9 first begin to close the second sash and then the first sash. Contacts 6.2 and 7.2, 8.2 and 9.2 are designed to eliminate the simultaneous shutdown of the reversing contactors 6 and 7, 8 and 9. 2 sludge.

The invention relates to gate mechanization and is intended to open and close swing gates, one of the flaps of which is provided with a bar.

The purpose of the invention is usability.

This goal is achieved by the fact that the limit switches provide the advance movement of the flap with the strip relative to the other flap during closing and prevent the flap from breaking.

FIG. 1 schematically shows swing gates with electric flaps; in fig. 2 - the circuit is electrical.

A device for opening and closing gates with flaps 1 and 2, the first of which is provided with a flap 3, comprises an electric drive 4 flaps 1, an electric drive 5 flaps 2, a contactor

9 for closing the leaf 2, the final shutdown: the open position 10 of the leaf 1, the limit switch 11 of the closed position of the leaf 1, the limit switch 12 of the open position of the leaf 2, the limit switch 13 from the closed position of the leaf 2, the button Closed 14, the button Open 15, and the button Stop 16. Food

the contactors 6-9 are supplied through the contacts of the Stop button 16: to the contactor 6 through the contacts of the end switch 10, the contacts of the button Closed 14, blocked by the contacts 6.1 of the contactor 6, and the contacts 7.2. of the contactor 7; to the contactor 7 - through the contacts of the limit switch 11,

terminal switches. 12, contacts 9.3 of contactor 9, blocked by contacts 7.1 of contactor 7, and contacts 6.2 of contactor 6; to the contactor 8 - through the contacts of the limit switch 11, the contacts of the limit switch 12, the contacts 6.3 of the contactor 6 blocked by the contacts 8.1 of the contactor B, the contacts 9.2 of the contactor 9; to the contactor 9 - through the contacts of the limit switch 13, the contacts of the button Open 15, blocked, the contacts 9.1 of the contactor 9, and the contacts 8.2 of the contactor 8. Electric drive

5 4 is connected to the power supply for opening by contacts 6.4, and for closing by contacts 7.3. Electric drive 5 is connected to the mains for opening by contacts 9.4, and for

0 closing - contacts 8.3.

The principle of operation of the device is as follows.

Pressing the button Closed 14, the contactor 6 is turned on and with its contacts 6.1 blocks the contacts of the button Closed 14, the contacts 6-4 turn on the actuator 4, and the shutter 1 begins to close. Wherein

pins 6.3 are closed. This is caused by

 The contact closure of the limit switch 11 and thus after some time the contactor 8 is turned on. The contacts 8.3 of the contactor 8 turn on the electric drive 5, 5 and the flap 2 starts to close. The first flap 1 turns out to be closed, and the contacts of the limit switch 10 turn off the contactor 6, contacts 6 „4 is opened and leaf 1 stops. Then, the leaf 2, the contacts of the limit switch 12 blur 5

The contactor is turned on and off. 8. The contacts 8.3 are opened, the shutter 2 is stopped.

When the Open 15 button is pressed, the contactor 9 is turned on and its contacts 9.1 block the contacts of the Open button 15, while the contacts of the limit switch 13 are closed. Contacts 9.4 turn on the actuator 5, and the shutter 2 opens. Then 10 is provided with a plate containing electrically closed contacts of the limit switch 12, the contactor 7 is turned on, the electric actuator 4 is turned on by the contacts 7.3 and the shutter 1 starts to open.

drives, contactors, limit switches of the open and closed positions of the gate leaves and push-button switches, in which each pair of contactors in the open position opens the terminals of one electric drive connected

clocks of the limit switch 13 and the contactor 9 is turned off. Then the contacts of the limit switch 11 are opened and the contactor 7 is turned off. The circuit is in the initial position. 20 When the Stop button 16 is pressed, its contacts open the supply circuit of contactors 6-9 and they turn off. Sash 1 and gate 2 stop movement.

Thus, due to the advance movement of the leaf 1 with the bar 3

with respect to the shutter 2, when closing, the shutter 2 is prevented from hitting the bar 3 and breaking it, thus ensuring ease of maintenance.
