Abstract

PURPOSE:To eliminate the sediment perfectly by providing plural nozzles in a nozzle unit freely to turn. CONSTITUTION:For example, when a carriage 50 is fixed to the upper part of a column 41 and a traveling truck 2 is moved right and left along a frame 1, a nozzle unit 4 is moved right and left over a material to be cleaned, and furthermore, the nozzle unit 4 turns nozzles 69, and a locus of the tip of the nozzle 69 performs the rolling to clean the material to be cleaned efficiently with a large quantity of high-pressure water per unit area, which is jetted to the surface of the material to be washed. The nozzles 69 are turned to wash the material to be washed, and when the nozzle unit 4 arrives at the other end, the nozzle unit 4 is stopped. At this stage, the nozzle unit 4 is moved downward at a certain distance, and stopped, and thereafter, the nozzle unit 4 is moved in the opposite direction. The material to be washed is thus washed.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high pressure water cleaning device, and more particularly to a high pressure water cleaning device for cleaning a crawler type vehicle.

[0002]

2. Description of the Related Art Crawler type vehicles include construction machines such as power shovels and bulldozers, agricultural machines and tanks. A traveling device of a crawler type vehicle has a crawler wound around a drive wheel and a driven wheel attached to a vehicle body, and the crawler is supported by rolling wheels attached to the vehicle body. When a crawler type vehicle is used for civil engineering work, etc., earth and sand adhere to the front surface of the crawler, the rear surface of the crawler and the vehicle body, the drive wheels, the driven wheels, and the rolling wheels.
The soil needs to be washed.

It has been proposed that an operator sprays high-pressure water with a hose to remove the deposited and deposited soil, or automatically sprays high-pressure water onto the object to be cleaned, but this is not always sufficient. .

[0004]

The development of an automatic device capable of completely removing the earth and sand of the object to be cleaned and efficiently removing the earth and sand has been awaited.

[0005]

In view of the above circumstances, therefore, the present invention is a traveling cart that reciprocates on a pedestal so that the soil on the body to be cleaned can be completely removed and efficiently removed. In the high-pressure water cleaning device in which a column for raising and lowering the nozzle unit is erected, the nozzle unit includes a plurality of nozzles, and the plurality of nozzles are rotatable.

[0006]

[Operation] The nozzle unit moves left and right on the pedestal, moves up and down on the column, and a plurality of nozzles rotate, so the trajectory of the nozzle tip makes a rolling motion and a high pressure per unit area injected onto the surface to be cleaned. Since the amount of water is large, the object to be cleaned can be efficiently cleaned.

[0007]

A roller chain is driven by driving the geared motor 43.
When the carriage 50 is raised by 49, the carriage 50 ascend limit switch dog 59 is raised.
The carriage 50 abuts 57 and stops at the top of the column 41.
On the other hand, when the carriage 50 descends, the descending limit switch dog 60 collides with the descending limit switch 58 and the carriage 50 stops at the lower part of the column 41. The raising and lowering of the carriage 50 can be arbitrarily set according to the state of adhesion of the soil on the body to be cleaned. That is, the carriage 50 can be run for a fixed distance and stopped, continuously raised and lowered, or directed downward or upward.

The nozzle unit 4 is attached to the carriage 50 as shown in FIGS. That is, the nozzle unit 4 is attached to the tip of the rotary nozzle bracket 66 extended from the carriage 50. The nozzle unit 4 includes a rotary nozzle housing 67 on the base end side, a rotary body 68 on the front end side, and a nozzle 69 arranged so as to face the rotary body 68 and bent so as to face the body to be cleaned. Although the example of two nozzles 69 is shown, more nozzles 69 can be provided if necessary. A geared motor 70 is attached below the rotating nozzle bracket 66, and a rotating body 68 having a nozzle 69 is rotated by the geared motor 70.

Next, the operation of this high-pressure water cleaning device will be described. Carriage 50 with nozzle unit 4 attached
Is moved left and right on the gantry 1 by driving the geared motor 68, and is vertically moved up and down by driving the geared motor 43 along the column 41. By driving the geared motor 70, the rotating body 68 including the nozzle 69 of the nozzle unit 4 rotates.

For example, when the carriage 50 is fixed above the column 41 and the traveling carriage 2 is moved left and right along the gantry 1, the nozzle unit 4 moves left and right above the object to be cleaned, and the nozzle 69 is moved. While rotating, it moves to the left and right, and the locus of the tip of the nozzle makes a rolling motion, so that the amount of high-pressure water per unit area sprayed onto the surface of the cleaning target is large and the cleaning target is efficiently cleaned. When the nozzle unit 4 reaches the end portion of the object to be cleaned after the preset traveling distance is measured by the rotary encoder 19, the traveling carriage 2 is stopped and the nozzle unit 4 is moved downward by a fixed distance to the column 41.
By stopping the column up and moving the column 41 to the left and right, the unwashed portion of the object to be cleaned is cleaned by the nozzle unit 4. The object to be cleaned is cleaned while rotating the nozzle 69, and when the other end is reached, the cleaning unit 4 is stopped, and the cleaning unit 4 is moved downward for a certain distance and stopped, and the nozzle unit 4 is moved in the opposite direction. In this way, the object to be cleaned is cleaned.
