[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation control method for an apparatus for cleaning a construction machine such as a power shovel or a bulldozer.

[0002]

2. Description of the Related Art Construction machines, such as power shovels and bulldozers, are equipped with a working machine on a vehicle body driven by a track-type traveling device, and perform earthworks at a civil engineering work site, etc. The track-type traveling device is mounted on a truck frame. A crawler belt is wound around the attached starting wheel and idler wheel, and the crawler belt is supported by an upper rolling wheel and a lower rolling wheel mounted on a truck frame. Since the construction machine is as described above, the crawler-type traveling device, particularly the surface of the crawler, between the back surface of the crawler and the upper and lower surfaces of the track frame, the starting wheel, the idle wheel, and the earth and sand are deposited by performing civil engineering, It is necessary to wash the deposited soil during inspection / repair or during transportation by truck or the like. Conventionally, an operator holds a hose and sprays high-pressure water to wash the soil.

[0003] In such a washing of earth and sand, mud is scattered with water to the worker, and the body is soiled, which is a very troublesome work. Accordingly, the present applicant has previously proposed a construction machine cleaning apparatus capable of solving the above-described problem.

The controller 41 selects the type, degree of contamination, nozzle travel distance corresponding to the cleaning location, nozzle vertical movement distance, nozzle swing. The movement trajectory of the nozzle 3 is set by selecting the angle and the number of times of nozzle reciprocation. Thereafter, the water pump start switch 52 is turned on to inject high-pressure water from the nozzle 3 and the automatic cleaning switch 54 is turned on to turn the nozzle 3 The nozzle 3 is moved along the above-mentioned movement trajectory by traveling, moving up and down, swinging the head, detecting them, and setting the selected value. , The movement of the nozzle 3 When moving finished, an operation control method for a construction machine cleaning apparatus characterized by stopping the water pump automatically. Second
In the invention of the first aspect, the nozzle 3 moves in one direction along the entire length of the crawler belt 60 in the crawler-type traveling device of the construction machine, then moves up and down a predetermined distance, and again moves in the other direction along the entire length of the crawler belt 60. The operation control method of the cleaning equipment for construction machines is characterized in that the nozzle 3 moves vertically and the crawler belt 60 is short and the other portions are long.

[0008]

According to the first invention, the travel trajectory of the nozzle 3 is set in advance by selecting the travel distance, the vertical movement distance, and the swing angle of the nozzle 3 according to the type of construction machine, the degree of dirt, and the location of dirt. The crawler-type traveling device of the construction machine can be efficiently cleaned with a simple operation because it automatically moves along the road. In other words, the degree of contamination of the track-type traveling device of the construction machine,
The stained portion is not constant and varies depending on the work site. Therefore, the nozzle 3 can be efficiently cleaned by moving the nozzle 3 along a movement locus corresponding to the degree of the stain and the stained portion. Also,
Since the nozzle 3 to be operated is selected by the operation selection switch 55, only the nozzle 3 facing the dirty crawler traveling device in the left and right crawler traveling devices is operated, and only the dirty crawler traveling device is operated efficiently. Can be washed well. In addition, a dirty portion of the crawler-type traveling device is selected by the washing position selection switch 47, and only the dirty portion can be efficiently cleaned by the nozzle 3. According to the second invention, the crawler belt 60 of the crawler-type traveling device is provided.
When cleaning the portion, the nozzle 3 moves up and down for a short distance, so that a large amount of high-pressure water is sprayed on the crawler belt 60 portion so that the portion can be sufficiently cleaned. Since the nozzle 3 moves up and down a long distance when cleaning the portion other than the crawler belt 60, the nozzle 3 moves faster when cleaning the portion other than the crawler belt 60 portion. Therefore, the crawler belt 60 where the degree of dirt is large can be sufficiently washed, and the other part where the degree of dirt is small can be efficiently cleaned because the nozzle 3 moves quickly.
