First relay 330 is disconnected (open) according to X-axis inclination value and setting value or is closed (close).That is, first after
Electric appliance 330 is disconnected when X-axis inclination value is more than setting value, and X-axis inclination value is closed when being less than setting value.
Second relay 335 obtains Y-axis inclination value from Y-axis processing unit 325.
Second relay 335 is disconnected or is closed according to Y-axis inclination value and setting value.That is, the second relay 335 is in Y-axis
It is disconnected when inclination value is more than setting value, Y-axis inclination value is closed when being less than setting value.
Abnormality detecting unit 340 controls driving motor 140 according to the first relay 330 and the second relay 335, with control
The action of cable wire 130.That is, when at least one in the first relay 330 and the second relay 335 is disconnected, abnormality detection
Unit 340 controls driving motor 140, to stop batching for cable wire 130, and can only carry out the debatching of cable wire 130, and cut off small
The power supply supply of vehicle 120, is driven with the left and right for stopping trolley 120.It batches and refers to that cable wire 130 rises, and debatching refers to cable wire 130
Decline.
When the first relay 330 and the second relay 335 in the closure state, abnormality detecting unit 340 passes through control
Make batching for cable wire 130 that can be realized with the left and right driving of debatching and trolley 120.
In addition, when at least one in the first relay 330 and the second relay 335 is disconnected, output unit 230 is defeated
Go out warning information.That is, the loud speaker 233 of output unit 230 can export warning information by sound, and output unit 230 is shown
Show that unit 235 can show warning information by written form, and the lamp unit 237 of output unit 230 can export police by light
It notifies breath.
Referring to the method for the safety of Fig. 4 and Fig. 5 description control cranes.
Fig. 4 is the flow chart for the crane safety control method for showing one embodiment of the invention, and Fig. 5 is for illustrating this hair
The exemplary plot of the crane safety control method of a bright embodiment.In addition, it clearly states herein, the sheet being described with reference to Fig. 3
The component of the controller 220 of inventive embodiments can be integrated or segment, therefore from the limitation of related names, perform above-mentioned function
Controller 220 component can become the embodiment of the present invention controller 220 component.Therefore, below to the present invention
When the method for controlling security of the crane 100 of embodiment is described, the main body of each step is not described with associated component,
But it is described based on controller 220.
Fig. 4 is referred to, controller 220 receives detection information (S410) from obliquity sensor 210.That is, inclination angle passes
Sensor 210 detects the inclination angle of pulley 150, and the detection information detected is supplied to controller 220.Controller 220 is from inclining
Angle transducer 210 receives detection information.
Controller 220 confirms the X-axis output voltage being included in detection information and Y-axis output voltage (S420).That is, control
Device 220 confirms the X-axis output voltage of X-direction being included in detection information and the Y-axis output voltage of Y direction.Wherein, X
Axis output voltage and Y-axis output voltage can be represented with mV units.
The confirmation of controller 220 is based respectively on X-axis output voltage and the X-axis inclination value of Y-axis output voltage and Y-axis inclination value
(S430).That is, X-axis output voltage is converted to X-axis inclination value by controller 220, and Y-axis output voltage is converted to Y-axis inclination angle
Value.
Controller 220 is based on X-axis inclination value and Y-axis inclination value judges whether to meet security control condition (S440).That is, control
Device 220 processed based on X-axis inclination value whether be more than setting value and Y-axis inclination value whether be it is more than Y-axis setting value to determine whether
Meet security control condition.
When meeting security control condition, controller 220 controls (S450) driving motor 140 and trolley 120.
That is when X-axis inclination value is more than setting value or Y-axis inclination value is more than setting value, controller 220 controls driving motor
140, to stop batching for cable wire 130, and debatching can only be carried out, and trolley 120 is controlled, it is driven with the left and right for stopping trolley 120.
That is, as shown in (a) of Fig. 5, when suspension hook 160 and pulley 150 are without departing from correct position, the control of controller 220 is driven
Dynamic motor 140, so as to can carry out cable wire 130 batch and debatching, and trolley 120 is controlled, so that the left and right of trolley 120 can be carried out
Driving.
But as shown in (b) of Fig. 5, when suspension hook 160 and the deviation correct position of pulley 150, controller 220 controls small
Vehicle 120 is driven with the left and right for stopping trolley 120.Controller 220 controls driving motor 140, to stop batching for cable wire 130, and
It can only carry out debatching.The weight being hung on as a result, on suspension hook 160 can decline under control of the controller 220.
When meeting security control condition, controller 220 exports warning information (S460).That is, when meeting security control item
During part, controller 220 can export warning information by sound, text importing and light.
Therefore, whether partially the safety control 200 of crane 100 of the invention can detect that pulley 150 and suspension hook 160
From correct position, by make cable wire 130 can only debatching, can safely handling weight, and to operator notify to deviate correct
Position, so as to ensure the safety of operator.
The preferred embodiment of the present invention is described above, but those skilled in the art is appreciated that do not surpassing
Go out the present invention described in claim thought and field in the range of the present invention can be carry out various modifications and changed.
