Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an improvement in a control device for a mobile bridge construction device.

[Conventional technology]

FIG. 4 shows a control device for a conventional mobile bridge construction device (hereinafter referred to as construction device). Bridge body 1 as shown in the figure
1.12. A position sensor 20 and a solenoid valve 21 are installed in the construction device 10 having a vehicle 13 and a main shaft 14. The signal from the position sensor 20 is sent to the position sensor input circuit 31, arithmetic circuit 33, and display drive circuit 3 of the control device 30.
4, the information is displayed on the display 41 in the operation panel 40 and the channel 40. The operator of the construction device 10 checks the display 41 and the status of the construction device 10 and instructs the next operation from the switch 42 of the control panel 40. The command signal is sent to the switch input circuit 35 of the controller 30. Arithmetic circuit 33, solenoid valve drive circuit 32
The signal is transmitted to the solenoid valve 21 through the electromagnetic valve 21 to operate the erection device 10.

The operator repeats the above operation nine times depending on the erection or removal operation.

[Problem that the invention seeks to solve]

In the conventional control device for the construction equipment described above, the solenoid valve 21 is driven by the switch 42 of the operation/main panel 40 in accordance with the erection or removal operation, and the other operation (switch switch selection). Erection equipment! The operation of 0 is as follows: Slide the divided bridge bodies 11 and 12 forward and remove the bridge body 11.
be integrated with. Slide the integrated bridge body forward again.

Lower the tip of the bridge and lower the rear end of the bridge. Move the vehicle 13 backwards and remove the main lug 14 (from the bridge body).

In addition, in the case of withdrawal, the above operation can be performed in reverse.

As described above, the operation of the erection device 10 is extremely complicated.

If an operator were to perform these complicated operations for each operation, it would take a long time to erect or dismantle the structure, and there is a high possibility of erroneous operation.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a control device for a mobile bridge construction device that allows easy understanding of the next operation to be performed and reduces the burden on the operator.

[Means for solving problems]

In order to achieve the above object, the present invention includes a storage means in which the contents of the operation to be performed for each operation of the mobile bridge construction device are stored, a display contents specifying means for specifying the display contents, and a display contents specifying means for specifying the display contents. The apparatus is comprised of a selection means for selecting the operation contents stored in the storage means, and a display means for displaying the operation contents selected by the selection means.

[Effect]

With this configuration, the contents of the operation to be performed by the operator are displayed on the display means, and the state of the erection device after the operation is also displayed, so that the burden on the operator can be reduced.

〔Example〕

Hereinafter, the present invention will be explained with reference to Figs. 1, 2, and 3. Here, only the points that are different from the fourth prisoner will be explained, and the other parts will be given the same reference numerals and their explanation will be omitted. do. A display designation switch 50 is provided on the operation panel 40 to designate the content of the operation to be performed.

Then, the signal from the display designation switch 50 is input to the display content calculation circuit 61 via the switch input circuit 60 which inputs the signal from the display designation switch 50 to the control device 30, so that the display content can be designated. Another control device! A display content storage circuit 63 is provided at 30, and the content to be displayed is stored in advance here.

Furthermore, a display content selection circuit 62 is provided in the control device 30, and the display content stored in the display content storage circuit 63 is selected based on the display content specified by the display content calculation circuit 61. Further, the output of the display content selection circuit 62 is sent to the display 20 via the display content output circuit 64.
Make it output to .

In such a configuration, a display signal is sent to the switch input circuit 60 by the display designation switch 50 of the operation panel 40.
The display content is specified by the output from the display content calculation circuit 61 via the display content calculation circuit 61, and based on this, the display content in the display content storage circuit 63 is selected in the display content selection circuit 6211C. The display content is output to the display 70 via the display content output circuit 64. The display 70 displays the contents of the operation to be performed by the operator in text and graphics.e Figure 2 shows a specific example of the display 70 and the operation channel 40. switch 50
a. The withdrawal switch sob distinguishes between erection and withdrawal, and the next operation switch 50c and the previous operation switch 50d distinguish between display contents. The operator selects the display contents of switches 50-J50d of type 411. In addition, there are provided a rear jib upper switch 42 & used to raise the rear jib, a rear jib lower switch 42b used to lower the rear jib, an arm upper switch 42c used to raise the arm, and an arm lower switch 42d used to lower the arm.

In the display 70, 70m is the erection device 10 after the operation is performed.
10a is a display section that shows the current position of the erection device 10 detected by the position sensor 20 in FIG. be.

FIG. 3 is a diagram showing in detail the display content calculation circuit 61, display content storage circuit 63, and display content selection circuit 61 shown in FIG. The content of the flop 61 is determined by the erection signal 61a and the withdrawal signal 61b. Front screen signal 61a
The next screen signal 61d enters the power input 9 input 611. Here, the counter 61f (which is an up/down counter, and the content goes down according to the previous screen signal 61a, and the next screen signal 61
The contents are uploaded by d. The contents of the clip frog 61e and the counter 611 are added by an adder 61g to determine the display contents. The display content storage circuit 63 stores the display content (1
) 6.7 a to display content (to)) 63n, and selected by display content selection circuit 62 9.

According to the embodiment described above, the operation (switch selection) to be performed for each operation of the erection device 10 is stored in the display content storage circuit 63, and the display 70 is The current position of the construction device 10 is displayed on the display section 70c, the operating procedure is displayed in text on the display section 70b, and the construction device 10 after the operation is displayed on the display section 70h.
Since the state of the operator is illustrated, it is easy to understand the operation contents that must be performed, and the burden on the operator is reduced.

〔Effect of the invention〕

The present invention described above includes a storage means in which the operation contents to be performed for each operation of the mobile bridge construction device are stored, a display contents specifying means for specifying the display contents, and a display contents specifying means for specifying the display contents. It is composed of a selection means for selecting the operation contents stored in the storage means according to a designation, and a display means for displaying the operation contents selected by the selection means.

With this configuration, it is possible to obtain a control device for a mobile bridge construction device that can easily understand the operation to be performed next and reduce the burden on the operator.
