a to 10a, and these operation input units 7a to
Each of the 10a is composed of an operation lever A that can be tilted from the neutral position in the forward and reverse directions by an operator, and a potentiometer B that outputs an operation signal according to the tilt of the operation lever A.

[0005]

The operation signal generator 12 in the conventional operating device for the hydraulic control unit of the mobile working machine is
Since the operation input sections 7a to 10a are each configured by the operation lever A and the potentiometer B, the exclusive space in the cab 11 is large, and the cab 11
There was a problem that the habitability of was worse.

An object of the present invention is to provide an operating device in which the operation input section 12 arranged in the operator's cab 11 has a small occupied space.

[0007]

In order to achieve the above object, an operating device for a hydraulic control device for a mobile working machine according to the present invention is constructed as follows. Hydraulic control unit 7 of mobile work machine
10 to 10, in particular, an operation signal generation unit 12 provided in the driver's cab 11 of the work machine 2 for generating an operation signal according to an operation of an operator, and an operation signal received from the operation signal generation unit 12 And a hydraulic pressure control unit 7 to 10 according to an operation signal from the operation signal generation unit 13.
The operation signal generating section 12 is: a display; an image display control section for displaying a graphic showing the operation input section of the controlled object of the mobile crane on the display screen of the display; A touch screen mounted on the display screen so as to cover at least a region where the graphic of the operation input unit is displayed, an interface connected to the touch screen, and a graphic portion of the operation input unit displayed on the display. An operation device for a hydraulic control unit of a mobile work machine, comprising: an interface for receiving touch information to the corresponding hydraulic control unit and outputting an operation signal corresponding to the touch information to the corresponding hydraulic control unit. .

[0008]

In the operating device of the present invention, the operator can control the corresponding hydraulic pressure control unit by touching the graphic portion of the operation input unit displayed on the display arranged in the cab 11 by the operator. The space occupied by the operation signal generator 12 in the driver's cab 11 can be reduced as compared with the conventional one.

[0009]

Embodiment An embodiment of the present invention will be described below with reference to FIG. The operating device of the hydraulic control unit of the mobile work machine of the present invention is
Compared with the conventional operating device shown in FIG. 3 and described above, only the structure of the operation signal generating unit 12 is different, and therefore, the structure other than this difference is the same as that used in the description of the conventional operating device described above. Are used as synonyms.

As shown in FIG. 1, the operation signal generator 12 of the operating device according to the present invention includes: a display 14, a display screen 14a of the display 14, a control target of the working machine (crane) 2 (of the swivel base 3). Revolving drive, telescopic boom 4
Undulation drive, telescopic boom 4 telescopic drive, winch hoisting and hoisting drive) image input control section 15 for displaying figures showing operation input sections 7a to 10a, on display screen 14a of display 14, at least A touch screen 16 attached so as to cover the area where the figures of the operation input units 7a to 10a are displayed, an interface 17 connected to the touch screen 16, and of the operation input units 7a to 10a displayed on the display 14. Take in touch information to the figure part,
An interface that outputs an operation signal corresponding to the touch information relating to the capture to the control signal generation unit 13.

The graphic portions displayed on the display 14 as the respective operation input portions 7a to 10a are fixed in the vertical direction from the neutral position corresponding portion O (the portion corresponding to the non-operating position of the hydraulic pressure control portions 7 to 10). The touch screen 16 is displayed as a figure having a region, and the touch screen 16 indicates whether the touched position is one of the operation input units 7a to 10a, the upper and lower regions, and the position above the neutral position O or The information capable of reading the downward distance is output to the touch information processing unit (the interface of the claim) 17. The configuration of the touch screen 16 is well known and will not be described.

When operating the hydraulic control units 7 to 10 of the hydraulic working machine, the operator inputs the operation input units 7a to 10a corresponding to the hydraulic control units 7 to 10 to be operated.
Touch the figure part of. Then touch screen 1
The above information is input to the interface 17 from 6. The interface 17 determines the hydraulic control unit to be operated and the operating direction of the hydraulic control unit based on the information related to the reading, determines the operation amount, and moves the corresponding hydraulic control unit to the corresponding direction. An operation signal for operating with a corresponding operation amount is output to the control signal generator 13. The hydraulic control unit 13 controls a predetermined hydraulic control unit according to this operation signal.

[0013]

According to the operating device of the hydraulic control unit of the mobile working machine of the present invention, which operates as described above, the hydraulic control units 7 to 10 of the hydraulic working machine can be operated in the same manner as the conventional operating device. However, since the space occupied by the operation signal generator 12 in the cab 11 can be reduced, the habitability of the cab 11 can be improved accordingly.

If the hydraulic working machine is a mobile crane, the operating information of the mobile crane (load factor of the crane, swing angle of the swivel base 3, hoisting angle of the telescopic boom 4, and It is common practice to attach an operation status indicator that displays the length of the telescopic boom 4 etc. In this case, this operation status display is also used as the display of the operating device of the present invention. This is even more effective.
