[0001] The utility model relates to the technical field of suction and lifting, in particular to an operating circuit of a suction and lifting device with remote control. Background Art

[0002] Suction lifting equipment usually includes a hanger assembly, a suction cup assembly and an electrical control assembly.

[0046] This application is divided into two major circuits, one is the vacuum pump working circuit and the other is the system control circuit. The circuit connection relationship of each circuit is as follows:

[0047] The vacuum pump working circuit includes: a fourth relay conversion contact, a first relay conversion contact, a two-color indicator light (red and green), a vacuum pump, a first relay dynamic contact, a local air release valve button light (yellow), a local air suction valve button light (green), a vacuum air release valve, and a fourth relay dynamic contact one.

[0054] The fourth relay normally closed contact second output terminal and the third relay normally closed contact output terminal are respectively connected to the second relay normally broken contact input terminal, and the second relay normally broken contact output terminal and the local deflation button output terminal are respectively connected to the fourth relay coil input terminal;

[0055] The second relay coil output end, the third relay coil output end, the fourth relay coil output end and the vacuum pressure abnormality sensor output end are respectively connected to the battery power input end.

[0056] Specific working principle:

[0057] This application realizes both manual and remote control of the suction and lifting equipment through the connection relationship between the 1# suction remote control switch, the 1# release remote control switch, the local suction button, the local release button, the vacuum pressure abnormality sensor, and the coils of the first relay to the fourth relay and different contacts. It is easy to operate and safe to use.

[0058] 1. The power button is set behind the 1# gas circuit receiver to ensure that the 1# gas circuit receiver is always powered. Other circuits are controlled by the power button. When the power button is turned on, the power button indicator light is on. When the power button is turned off, the power button indicator light is off. The battery power display connected in parallel can display the battery power in real time when the power button is turned on.

[0059] 2. In the present application, when the static contact 2 of the fourth relay conversion contact is connected with the moving contact, the circuit connected in series between the vacuum venting valve and the fourth relay dynamic contact 1 is connected in parallel with the local venting valve button light, so as to display that the suction and lifting equipment is in a working state of venting to relieve negative pressure or relieve vacuum, and the outside gas enters the suction cup through the vacuum venting valve, the negative pressure is relieved, and the object sucked by the suction cup finally leaves the suction cup; when the static contact 1 of the fourth relay conversion contact is connected with the moving contact, the circuit containing the vacuum pump is connected in parallel with the local suction valve button light, so as to indicate that the suction and lifting equipment is in a suction and vacuum working state, which either maintains a certain negative pressure or is vacuuming and the negative pressure has reached a certain threshold, and the suction cup of the suction and lifting equipment adsorbs the object.

[0060] 3. When the vacuum pressure is normal, the second input terminal of the vacuum pressure abnormality sensor is in a power-off state, the first relay coil is power-off, the first relay moving contact remains disconnected, and the vacuum pump does not work. At the same time, the static contact 1 of the first relay conversion contact is connected to the moving contact, the static contact 1 of the first relay conversion contact is connected to the green indicator input terminal of the two-color indicator light, the static contact 1 of the fourth relay conversion contact is connected to the moving contact, and the green indicator light is on, indicating that the pressure is normal;

[0061] When the vacuum pressure is abnormal, the opposite is true. At this time, the input terminal 2 of the vacuum pressure abnormality sensor is energized, the first relay coil is energized, the static contact 2 of the first relay conversion contact is connected to the moving contact, and the static contact 2 of the first relay conversion contact is connected to the red indicator light input terminal of the two-color indicator light. The red indicator light is on, indicating that the pressure is abnormal and vacuum is being drawn. At the same time, the moving contact of the first relay remains in the energized state, and the vacuum pump works until the pressure returns to normal.

[0062] Fourth, whether it is the local suction button or the 1# suction remote control switch, they are all connected to the second relay coil. When the button or switch is triggered, the second relay coil is energized, and the second relay break contact is disconnected, destroying the self-locking connection circuit composed of the fourth relay coil and the fourth relay close contact 2. The fourth relay coil is de-energized, and the fourth relay close contact 1 remains disconnected. The vacuum deflation valve does not work, and the valve remains closed. Through the working principle described above of the vacuum pressure abnormality sensor, the vacuum is automatically pumped to reach the normal vacuum pressure state;

[0063] When the local deflation button or the 1# deflation remote control switch is pressed to trigger the deflation operation, the local deflation button is pressed and turned on, the fourth relay coil is energized, the fourth relay normally closed contact 1 is turned on, the vacuum deflation valve works, the valve opens, the outside gas enters the system, the negative pressure or vacuum is destroyed, and the deflation effect is achieved. At the same time, because the local deflation button or the 1# deflation remote control switch is an electric switch, after being triggered, the fourth relay coil, the second relay normally closed contact and the fourth relay normally closed contact 2 form a self-locking structure, keeping the fourth relay coil energized until the deflation is completed;

[0064] The self-locking structure composed of the fourth relay coil, the second relay break contact and the fourth relay make contact can release the self-locking and immediately stop deflation as long as the local suction button or the 1# suction remote control switch is pressed. In addition, it can also ensure that when the suction and deflation actions occur at the same time, the self-locking is released, the suction action is executed, and the deflation action is stopped, ensuring the safety of the suction and lifting equipment. Because deflation means putting down the adsorbed object, more attention should be paid to the safety of operation.

[0065] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
