Abstract

An embodiment of the present invention relates to an apparatus for controlling quick clamping of construction machine which comprises a clamp for mounting an attachment, the apparatus including: a selection input unit for generating a selection signal during an on operation by an operator; an operation input unit for generating an operation signal during an operation by the operator; a clamp driving unit for releasing and fastening the clamp; and a controller for controlling the clamp driving unit to release the clamp while the operation signal is input after the selection signal is input.

Claims (48)

1. An apparatus for controlling quick clamping of construction machine which comprises a clamp for mounting an attachment, the apparatus comprising:

a selection input unit for generating a selection signal during an operation by an operator;

an operation input unit for generating an operation signal during a pressing operation by the operator;

a clamp driving unit for releasing and fastening the clamp; and

a controller for controlling the clamp driving unit to release the clamp while the operation signal is input after the selection signal is input,

wherein

the operation input unit is configured to generate the operation signal while the operator holds the pressing operation,

the controller is configured to control the clamp driving unit so that the clamp is in a released state while input of the operation signal continues, and

the operation input unit includes a plurality of operation input units configured to be simultaneously operated by both hands of the operator.

2. The apparatus of claim 1 , wherein the operation input unit comprises a left joystick including one of a plurality of operation buttons or switches, and a right joystick including one of a plurality of operation buttons or switches.

3. The apparatus of claim 2 , wherein in response to the pressing operation on one of the plurality of operation input units being stopped, the controller is configured to control the clamp driving unit to fasten the clamp.

4. The apparatus of claim 1 , further comprising an output unit for outputting at least one of an alarm message or a warning sound,

wherein in response to the controller receiving the selection signal, the controller is configured to control the output unit to output at least one of the alarm message or the warning sound.

5. The apparatus of claim 4 , wherein in response to the selection input unit being switched off and generation of the selection signal being stopped, the controller is configured to control the output unit to stop outputting the warning sound.

6. The apparatus of claim 1 , wherein

the controller is configured to

monitor input of a pilot cutoff signal, and

control the clamp driving unit so that the clamp is released only when the pilot cutoff signal is not input.

7. An apparatus for controlling quick clamping of construction machine which comprises a clamp for mounting an attachment, the apparatus comprising:

a selection input unit for generating a selection signal during a first operation by an operator;

an operation input unit for generating an operation signal during a second operation by the operator;

a clamp driving unit for releasing and fastening the clamp; and

a controller for controlling the clamp driving unit to release the clamp while the operation signal is input after the selection signal is input,

wherein

in response to the selection input unit being switched off and generation of the selection signal being stopped, the controller is configured to activate a specific function mode controlled by the operation signal generated from the operation input unit; and

in response to the selection input unit being switched on and the selection signal being input, the controller is configured to deactivate the specific function mode controlled by the operation signal generated from the operation input unit.

8. The apparatus of claim 7 , wherein

the operation input unit comprises a left joystick including one of a plurality of operation buttons or switches and a right joystick including one of a plurality of operation buttons or switches and

the operation input unit is configured to be simultaneously operated by both hands of the operator.

9. The apparatus of claim 8 , wherein

when the specific function mode is activated,

one of the plurality of operation buttons or switches at the left joystick is associated with an engine deceleration selection signal output, and

one of the plurality of operation buttons or switches at the right joystick is associated with a pressure-up selection signal output.

10. A method of controlling quick clamping of construction machine which comprises a clamp for mounting an attachment, the method comprising:

a selection signal being input to a controller, the selection signal generated when an operator switches on a selection input unit;

an operation signal being input to the controller, the operation signal generated when the operator presses an operation input unit; and

a controller controlling the clamp to be released while the operation signal is input after the selection signal is input,

wherein

the operation input unit generates the operation signal while the operator holds a pressing operation,

the controller controls the clamp driving unit so that the clamp is in a released state while input of the operation signal continues, and

the operation input unit includes a plurality of operation input units which are simultaneously operated by both hands of the operator.

11. The method of claim 10 , wherein

the operation input unit comprises a left joystick including one of a plurality of operation buttons or switches and a right joystick including one of a plurality of operation buttons or switches.

12. The method of claim 10 , wherein

the controller deactivates a specific function mode, controlled by the operation signal output from the operation input unit, after the selection signal is input, and

the controller activates the specific function mode of the operation input unit when generation of the selection signal is stopped by switching off the selection input unit.

13. The method of claim 10 , wherein the controller controls an output unit to output at least one of an alarm message or an alarm sound after the selection signal is input, and

outputting of at least one of the alarm message or the alarm sound is stopped when the operator switches off the selection input unit.
