Next, in order to teach the washing height H of the construction machine 1 to be washed, the high-pressure washing nozzle 66 is manually raised by the raising / swinging right switch 105b, and then the model selection is made. It is set by the switch 103. Then, the automatic operation switch 95 of the operation selection unit 91 is pressed to start the cleaning by using the general-purpose combined cleaning arithmetic / control circuit 114f.

First, the nozzle moving carriage 13 is moved by the moving right limit proximity switch 55 or the moving left limit proximity switch 56.
However, the left and right movements are continued until the metal block 18 is detected. When the moving right limit proximity switch 55 or the moving left limit proximity switch 56 detects the metal block 18, the high-pressure cleaning nozzle 66 descends by the determined descending amount h after one stroke. When the lowering ends, the moving right limit proximity switch 55 or the moving left limit proximity switch 56 again moves left and right until the metal block 18 is detected.

Thus, the cleaning length L and the cleaning height H corresponding to the model code are read, the movement allowance E from 110b of the first storage unit 110, and the position SP of the nozzle moving carriage 13 at the time of switching the lateral swing direction are read. , 110c of the first storage unit 110 calls the high-pressure cleaning nozzle swing angle data.

Next, when the dirt level is designated through the dirt selection switch 99, the descending amount h after one stroke of the high-pressure washing nozzle 66 is called by the combination of the model code and the dirt level.

Then, the cleaning length L in step S20 is calculated by the calculation / control circuit 114c for cleaning in combination with the storage model data.
/ 2 and the low-pressure washing nozzle lateral swing switching position Y are calculated, an operation selection for selecting whether to wash the left side surface, the right side surface, or both side surfaces of the construction machine 1 to be cleaned, the right side,

When the operation selection switch 102 is neither on the left side nor on the right side, as shown in S45, it moves to the left side to the right side and to the right side, and the left side and the right side movement pulse counter in S46 indicate the cleaning length L / 2. Until line 131 of
The leftward leftward movement and the rightward rightward movement of S45 are continued.

Next, it is judged whether or not the sum of the cleaning height H in S47 and the descending amount h of the high pressure cleaning nozzle after one stroke is equal. If they are equal, it is set for each model by the position of the operation selection switch 102 in S48. Also, based on the data of the cleaning length L,
The nozzle moving carriage 13 moves to the home position 130, then moves to the marking position 130m in step S49, and ends.

Further, it is judged whether the sum of the cleaning height H in S47 and the descending amount h of the high pressure cleaning nozzle after one stroke is equal, and if they are not equal, the low pressure cleaning nozzle direction switching process of step S50 is performed.

Next, the low pressure cleaning nozzle direction switching process of step S50 will be described. As shown in S51, when the position of the operation selection switch 102 is on the left side, and when the nozzle moving carriage 13 is moving to the left and the left in the procedure of S52, the low pressure cleaning nozzle 37 of the nozzle moving carriage 13 moves to S53. Leftward swing (position 37a in FIG. 15), the left movement pulse counter in S54 indicates that the low-pressure cleaning nozzle lateral shake switching position Y =

Then, the operation selection switch 102 is set to S50.
As shown in 1, when the nozzle moving carriage 13 is moving to the right on the right side in the procedure of S502, the low pressure cleaning nozzle 3
7 is rightward swing of S503 (position 37a in FIG. 15)
Then, the right movement pulse counter in S504 continues to swing rightward in S503 until the low-pressure cleaning nozzle lateral vibration switching position 137 is reached, and when the low-pressure cleaning nozzle lateral vibration switching position 137 is reached, the low-pressure cleaning nozzle 37 in S505 moves to the right left. Swing (position 37e in FIG. 15).

Further, in the procedure of S502, the nozzle moving carriage 1
When 3 is not moving to the right and right, the low pressure cleaning nozzle 37 is
Swing left or right in S506 (position 37e in FIG. 15), and press S

The cleaning nozzle 37 is switched to the right swing to the right (position 37a in FIG. 15).

Further, when the operation selection switch 102 is neither on the left side nor on the right side, the steps S51 and S501 are simultaneously processed. In addition, the movement allowance E
Then, the lateral swing direction SP may be E = 0 and SP = 0.

Then, the horizontal movement processing of step S60 is performed until the low pressure cleaning nozzle direction switching processing of step S50 is completed, and the step S5 is performed until the horizontal movement processing of S70 is completed.
The low pressure cleaning nozzle direction switching process of 0 is performed. Also, S70
Upon completion of the left-right movement process, the process moves to the high-pressure washing nozzle lowering process of step S80.

Then, in response to the instruction signal from the operation selection switch 102, the procedure moves to step S80, and the high pressure cleaning nozzle lowering process calculation is started as follows. The operation selection switch 102
When the position is on the left side as shown in S81, the high pressure cleaning nozzle 66 of the left nozzle moving carriage 13 (L / H) descends in the procedure of S82, and the left descending pulse counter of S83 changes the high pressure cleaning nozzle. After one stroke of, until the descending amount h,
If the descending amount h is reached after one stroke by continuing to descend in S82, S
The left side high pressure washing nozzle 66 of 84 is completely lowered.

Further, the operation selection switch 102 is set to S85.
As shown in, when the right side, the high pressure cleaning nozzle of the right nozzle moving carriage 13 (RH) is lowered in the procedure of S86 until the right lowering pulse counter of S87 reaches the descending amount h after one stroke. , S86 is continued to descend, and when the descending amount is h after one stroke, the right high-pressure cleaning nozzle 66 in S88 is completed to descend.

If the operation selection switch 102 is neither on the left side nor on the right side, as shown in S801,
The right high-pressure cleaning nozzle 66 descends, and the left side of S802 and the right descending pulse counter until the descending amount h reaches S.
The high pressure cleaning nozzles 66 on the left side and the right side of 802 continue descending, and when the descending amount h after one stroke, the descending on the left side and the right side of S803 is completed.

When the high-pressure cleaning nozzle lowering process S80 is completed, the process returns to step S47, and it is judged again whether the cleaning height H is equal to the sum of the descending amount h after one stroke. If they are equal, the process moves to the home position process of S48, and the nozzle moving carriage 13 moves to the home position 130. Next, the process moves to the marking position moving process of S49, the nozzle moving carriage 13 is moved to the marking position 130m, and the cleaning is completed.

In step S10 of model data cleaning P in step S3, when the program selection switch 94 is switched to the model data position and model data cleaning P is performed, the dirt selection switch 99 of the operation selection section 91 is switched. Since the descending amount h can be changed after the first stroke, various cleaning methods can be selected.

Next, the procedure when the program selection switch 94 of the operation selecting section 91 is switched to the general purpose in step S1 of FIG. 17 and the general cleaning Q of S4 is selected will be described with reference to FIG. First, as in step S101, the metal block 18 is placed on the lower flange portion 38 facing the outside of the long guide rail 11 according to the length of the portion to be cleaned of the construction machine 1 to be cleaned.

Next, in order to teach the washing height H of the construction machine 1, the high pressure washing nozzle 66 is manually operated to the washing height of the washing portion of the construction machine 1 by moving the raising / lateral shaking right side selection switch 105a. Press to raise. Next, the cleaning height H is set by the model selection switch 103 of the operation selection section 91. A preset descending amount h after one stroke is read out to the operation selecting section 91.

Further, by changing over the dirt selection switch 99 of the operation selection section 91, the descending amount h after one stroke can be changed, so that various cleaning methods can be selected.

Next, the automatic operation switch 9 in step S102.
When 5 is pressed (ON), the up / down lower limit proximity switch 72 in S103 shifts to a determination as to whether or not the lower limit position of the high pressure cleaning nozzle 66 is detected. If not detected, the cleaning height H in step S106 and high pressure It is determined whether or not the sum of the descending amounts h of the cleaning nozzles 66 is equal. If they are not equal, the nozzle moving carriage 13 is moved left and right in S107, and the moving right limit proximity switch 55 installed in the nozzle moving carriage 13 in S108,
The moving left limit proximity switch 56 continues the horizontal movement in step S107 until it detects the metal block 18.

When the moving right limit proximity switch 55 and the moving left limit proximity switch 56 installed in the nozzle moving carriage 13 detect the metal block 18, the horizontal movement of S109 is stopped. Subsequently, the high pressure cleaning nozzle 66 in S110 starts to descend. After that, the process proceeds to S111, and the descending amount of the high-pressure cleaning nozzle 66 is descended until the descending amount h after one stroke becomes equal.

When the descending amount of the high-pressure cleaning nozzle 66 becomes equal to the descending amount h after one stroke, the high-pressure cleaning nozzle 66 is set to S1.
As shown in 12, the descent is stopped, the process returns to S107,
Then, it is determined whether or not the up / down lower limit proximity switch 72 has detected the lower limit position of the high pressure cleaning nozzle 66. As described above, while the proximity lowering switch 72 for raising / lowering lower limit does not detect the lower limit position of the high pressure cleaning nozzle 66, or while the cleaning height H and the total amount of lowering of the high pressure cleaning nozzle 66 are not equal, the nozzle moving carriage is 13 reciprocates between the metal blocks 18 placed on the guide rails 11.

Then, the proximity lower limit switch 72 for raising and lowering the
When the lower limit position of the high-pressure cleaning nozzle 66 is detected, or when the cleaning height H is equal to the total amount of lowering of the high-pressure cleaning nozzle 66, the nozzle moving carriage 13 returns to the home position 130 of S48, and thereafter. , Move to the marking position 130m in S49 and end.

The fully automatic operation has been described above with reference to the flow chart of FIG.
14 is a calculation model / control circuit for the storage model data 114a for high pressure cleaning, and a calculation model / control circuit for the storage model data 114b for low pressure cleaning
A control circuit, a calculation / control circuit for washing with storage model data 114c, a general-purpose high-pressure cleaning calculation / control circuit for 114d, a general-purpose low-pressure cleaning calculation / control circuit for 114e, and
Since a general-purpose combined cleaning calculation / control circuit of 14f is provided,
According to the construction machine 1 to be cleaned, the left and right automatic cleaning devices 10 can individually clean the left and right cleaning parts of the construction machine 1 by each independent operation, and the high pressure cleaning nozzle 66
Therefore, it is apparent that the single low-pressure cleaning nozzle 37 can also be automatically operated independently.

Further, it is apparent from the configurations of the operation selecting section 91 and the controller 92 that manual operation and automatic operation programs of general-purpose models are additionally stored.

[0113]

As described above, the present invention provides the automatic cleaning device 10 for the construction machine 1 having the effects as described below.

Low pressure cleaning nozzle 37 and high pressure cleaning nozzle 66
Since the nozzle moving carriage 13 in which is installed can be moved left and right along the guide rail 11, the soil adhered to and adhered to the underguard portion 2 and the underbody portion 3 of the frame of the construction machine 1 can be removed from the high pressure washing nozzle 66. Blow away the spouted washing water at a high pressure so as to cut off the part. Also,
The large amount of cleaning water discharged from the low-pressure cleaning nozzle 37 can cleanly wash away the adhered and fixed soil remaining in a block. Further, the mud-like earth and sand that has fallen to the washing place A is also flowed up to the mud reservoir in the pit, so that washing at the washing place A after the washing is unnecessary.

Further, the high-pressure cleaning water ejected from the high-pressure cleaning nozzle 66 draws a waveform trace of a width that swings up and down of the high-pressure cleaning nozzle 66, and the underguard portion 2 of the frame of the construction machine 1 and Then, the earth and sand attached to and fixed to the underbody part 3 are blown off so as to be cut off. Then, a large amount of cleaning water discharged from the low-pressure cleaning nozzle 37 that can be swung in the up, down, left, and right directions adheres to the block shape remaining in the waveform.
Moreover, the adhered earth and sand can be washed away quickly, and the adhesion of mud due to splashing can be prevented, so that the washing time can be shortened and the washing efficiency can be improved.

Further, the controller 92 has a controller 92 for controlling the drive mechanism means 14 and 15, and the controller 92 stores the shape data of the plurality of construction machines 1 to be cleaned, the high pressure cleaning nozzle 66, and the high pressure cleaning nozzle 66. The second storage unit 111 for storing the operation procedure of the low-pressure cleaning nozzle 37 is provided, and the shape data selected by the operation selection unit 91 provided on the operation panel 17 and the operation procedure are read out to execute the cleaning. Depending on the model of the construction machine 1 and the degree of dirtiness, the operator of the car wash device can immediately select the wash pattern,
The automatic cleaning device 10 can be efficiently and automatically operated.

Further, when the construction machine 1 is washed without using the shape data, the program selection switch provided in the operation selection section 91 has a controller 92 for controlling the respective drive mechanism means 14 and 15. After the general purpose is selected by 94, the operation procedure is read from the second storage unit 111 into the comparison calculation / control circuit 114, and after the car wash length L and the wash height H are taught, the wash can be executed. It is also possible to wash only the severe parts.

When cleaning is performed using the storage model data combined cleaning / calculation / control circuit 114c, the movement path 1
Since the parameter h constituting 20 can be made variable by switching the dirt selection switch 99 of the operation selection unit 91, even when the same construction machine 1 is washed, it can be washed by a washing method with a different movement locus.

In the case of general-purpose cleaning for cleaning the construction machine 1 without using the shape data, the operation / control circuit for combined general-purpose cleaning is switched by switching the dirt selection switch 99 attached to the operation selection section 91. Since 114f is used to change the descending amount h of the cleaning height H after one stroke, and the cleaning length L and the cleaning height H are taught, the cleaning can be performed, so that it is possible to clean only the heavily soiled portion. At the same time, it is possible to clean a wide variety of construction machines 1 for various purposes.
