Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device for a mobile bridge construction device.

[0002]

2. Description of the Related Art FIG. 3 is a view showing a control device for a conventional mobile bridge erection device (hereinafter abbreviated as "erection device").
The erection device (not shown in the figure) includes a position sensor 20 for detecting the position of the drive unit of the movable bridge erection device,
A solenoid valve 21 that drives the erection device is installed. The signal of the position sensor 20 is transmitted through the position sensor input circuit 31, the arithmetic circuit 33, and the display drive circuit 34 of the control device 30.
It is displayed on the display 41 in the operation panel 40.

A display content storage circuit 63 in the control device 30
Stores the particular state of the erection equipment to be displayed. The display content selection circuit 62 selects the display content stored in the display content storage circuit 63 based on the display content designated by the display content calculation circuit 61.

When the display contents are designated by the display contents designation switch 43, the contents of the display contents storage circuit 63 are selected by the display contents calculation circuit 61 and the display contents selection circuit 62 through the switch input circuit 60, and the contents are displayed through the display contents output circuit 64. The designated display contents are displayed on the display device 70.

The operator of the erection device displays the position information of the drive unit of the erection device based on the signal of the position sensor 20 displayed by the display 41 and the designated display content displayed by the display 70. Check the status of the installation equipment,
The next operation is commanded from the switch 42 of the operation panel 40. The command signal is a switch input circuit 35 of the control device 30,
It is transmitted to the solenoid valve 21 through the arithmetic circuit 33 and the solenoid valve drive circuit 32 to drive the erection device.

An example of the display on the display 70 is shown in FIG.
The display is designated by the display content designation switch 43, and the displayed content is in a stationary state. For example, FIG. 4A shows a state in which the bridge 3 is raised by the support arm 5. Looking at the display in FIG. 4 (a), the operator selects the switch 42
When the operation of the erection device is instructed from, the support arm descends and the bridge body 2 and the bridge body 3 are integrated. At this time, display 7
At 0, it is possible to display the state in which the bridge body 2 and the bridge body 3 are integrated after the bridge body 2 and the bridge body 3 are integrated as shown in FIG. 4B.

[0007]

In the above-described conventional control device for a erection device, the condition of the erection device displayed on the display 70 is limited to a specific stationary state. For example, in FIG.
In the above, it is not possible to display the progress of the bridge body 2 and the bridge body 3 of the erection device as one unit. For this reason, it is difficult for the operator to make a judgment on the situation in the middle of the process, which is a heavy burden.

The present invention has been made in consideration of the above-mentioned problems, and an operator can be displayed by displaying the progress of the bridge body 2 and the bridge body 3 of the erection device being integrated as time passes. It is an object of the present invention to provide a control device for a mobile bridge erection device that can reduce the burden on the user.

[0009]

SUMMARY OF THE INVENTION The present invention relates to a control device for a mobile bridge erection device, the position detecting means for detecting a position of a drive part of the mobile bridge erection device, and a physical positional relationship between the drive part. It is characterized by comprising a storage means for storing, a display content calculation means for calculating the display content from the position detection means and the storage means, and a display means for displaying the display content.

[0010]

According to the present invention, in the control device for the mobile bridge erection device, the stored position of the drive part is stored based on the position of the drive part of the mobile bridge erection device detected by the position sensor. The situation in the erection device is calculated from the positional relationship of the mechanical units, and the progress of the bridge 2 and the bridge 3 of the erection device being integrated is continuously displayed on the display means with the lapse of time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an overall configuration diagram showing an embodiment of the present invention. In the figure, the same parts as those in FIG. 3 are designated by the same reference numerals and the description thereof will be omitted. FIG. 2 shows a display example on the display 70 of FIG.

In FIG. 1, the control device 30 in the erection device
The mechanism position storage circuit 81 is provided in the. The mechanism position memory circuit 81 includes physical units such as the vehicle body 1, the bridge body 2, the bridge body 3, the main jib 4, the support arm 5, and the rear jib 6 in the erection device at each position of the drive unit detected by the position sensor 20. Memorize the positional relationship. When the position sensor detects the position of the drive unit, the erection is performed based on the stored physical position relationship of the vehicle body 1, bridge 2, bridge 3, main jib 4, support arm 5, rear jib 6 in the erection device. An image of the status of the device can be displayed on the display 70.

Further, the control device 30 is provided with a display content calculation circuit 80. This is to calculate the situation of the vehicle body 1, bridge 2, bridge 3, main jib 4, support arm 5, rear jib 6, etc. in the erection device from the position signal of the position sensor input circuit 31 and the mechanism position memory circuit 81.
