DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a locking instruction device for an earth drilling excavator, and more particularly to a locking operation of a rocking kerber in a digging operation using the locking keriber. .

[0002]

2. Description of the Related Art In a conventional locking operation of a locking kerber, since a lock position is underground, a lock operation cannot be performed visually, and an operator operating the lock operation cannot calculate a numerical value from a depth gauge or perform intuition. , Operation and experience were required, operation was difficult, and the burden on the operator was heavy.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to facilitate locking work of a locking kerber in an excavation operation using a rocking kerber by an earth drill digging machine. An operation instruction is issued. As a result, an accident or the like due to uncertainty of the lock is prevented, and the burden on the operator is reduced.

[0004]

The present invention has a bucket depth gauge, a lock device position detector, a lock position determination calculator, and a lock position indicator, and locks a lock device at a lock position of a locking kerber. Means for reading a bucket depth from the bucket depth meter into the lock position determination arithmetic unit, and means for reading a lock device position from the lock device position detector. Means for storing locking key bar lock position and dimension data inputted in advance, means for obtaining each lock position from the read bucket depth and stored locking button lock position and dimension data, and a locking device. Means for determining whether the position is a lockable position, a lockdown position or a lockup position; and Lockable signal corresponding to the position,
Means for outputting a lock-down signal or a lock-up signal is provided, and a locking instruction is displayed by inputting one of the signals to a lock position indicator.

[0005]

The operation will be described with reference to the block diagram of FIG. 3 showing the configuration of the present invention. The bucket depth is read from the bucket depth meter 4 into the lock position determination calculator 2, and each lock position is obtained by calculation from the locking key-bar lock position dimension data stored in the calculator 2. If the lock device is determined to be in the lockable position, a lock enable signal is output.
When the lock position is shifted vertically, a lock-up signal and a lock-down signal are output to the lock position display 3 to display a locking instruction (see FIG. 2).

[0006]

An embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a side view of an earth drill excavator provided with the locking instruction device of the present invention. 1 is an earth drill excavator main body, 2 is a lock position judging calculator attached thereto, 3 is a lock position indicator for indicating the lock position to the operator, 4 is a bucket depth gauge, 5 is a lock device position. It is a detector. FIG. 2 shows a lock position indicator 3 which displays the lock position by an output signal from the lock position determination calculator 2 and issues an operation instruction.

Next, the processing flow of the locking instruction device according to the present invention will be described with reference to FIGS. FIG. 4 is an explanatory view showing the lock position of the lock device and the locking kerber, and the lock position display range. For each lock position, a display range for displaying the lock position is provided around the lock position, and the range is further divided into three, which are lockdown, lockable, and lockup ranges.

First, the bucket depth is read into the arithmetic unit 2 from the bucket depth meter 4 (step 1). Next, the lock device position is read from the lock device position detector 5 (step 2).
Each lock position is determined based on the bucket depth and the locking key bar lock position dimension data input in advance (step 3).

It is determined whether the lock device 6 is within the lock position display range (step 4). If the lock device 6 is within the lock position display range, the process proceeds to the next step 5, where the lock device position is within the lockable range. If there is, a lock enable signal is output (step 6). If it is out of the lockable range, it is determined whether or not the lock device position is in the lockdown range (step 7). If it is in the range, a lockdown signal is output (step 9). A signal is output (step 8).

A lock enable signal output from the arithmetic unit 2,
The lock-down signal and the lock-up signal are input to the lock position indicator 3, and the lamps (lockable lamp, down lamp, up lamp) corresponding to each signal are turned on (see FIG. 2).

[0011]

The operator only needs to perform the lever operation in accordance with the lamp of the lock position indicator, so that the locking can be performed faster and more reliably than in the conventional locking operation.
