Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for spraying high-pressure water from a nozzle of a gun to perform surface treatment of concrete, painted surface, etc., and a surface treatment method using the same.

[0002]

2. Description of the Related Art Various types of guns with vacuum suction are used for treating a ceiling surface or a wall surface of an object to be processed, but they exhibit performance only when an object surface is substantially horizontal or vertical. If the target surface has an inclination, the only way to do this is to rely on a robot that can suck and move in a vacuum on the target surface, but there is unevenness on the surface such as concrete surface, or in the middle. For the target surface whose inclination changes, there is a problem that sufficient vacuum suction and movement cannot be performed, and it is not always possible to reliably follow and move to perform surface treatment.

[0003]

SUMMARY OF THE INVENTION The conventional drawbacks of the surface of the target surface, which was a problem in the following, have been improved, and the non-uniformity of the target surface, the inclination of the surface, etc. can be conveniently followed. An apparatus that enables surface treatment of a target surface and a surface treatment method using the same are provided.

[Means for Solving the Problems] (1) A high-pressure water gun having a vacuum suction port has a right-angled quadrilateral frame that can move on orthogonal XY planes by a combination of a motor, hydraulic pressure, a chain, a linear guide, a ball screw, and the like. It is attached to the moving axis of the XY table in the direction of the surface to be processed, and universal casters of equal length are attached to the surface to be processed at the four corners of the frame of the XY table. (2) Opposite to the surface to be processed of the XY table Shock absorbers are installed at the four corners of the side frame (3) The opposite side of the shock absorber frame is connected by a common stand, and a universal joint is installed at the center of the stand on the side opposite to the shock absorber. Has a coil spring or equivalent function, and a telescopic support leg that expands and contracts in proportion to the applied load is attached. 4) At the base of the telescopic support leg, attach a lifting mechanism such as a wire rope, a chain, or a cylinder that separately raises and lowers the support leg itself. (5) A rotary table is attached to the tip of the support leg. (6) The vacuum suction hose connected to the vacuum generator is connected to the vacuum suction port of the vacuum suction gun, and of course, the high pressure water hose and the air motor for rotating the gun are driven. Air hose etc. are also connected. A brush is attached to the part of the high-pressure water gun that contacts the surface to be processed.

[0005]

(1) The high-pressure water gun attached to the XY table because the surface formed by the tips of the free casters of equal length is parallel to the frame of the XY table when the device contacts the surface to be processed. The moving surface is parallel to the surface to be treated. (2) The high-pressure water gun is equipped with a vacuum suction hose for vacuum suction and a high-pressure hose for supplying high-pressure water. While moving in contact with the object to be treated, the surface treatment is performed. (3) The water hit and the waste material after the surface treatment are kept airtight by the brush part attached to the high pressure water gun in contact with the object, While sucking outside air, vacuum is immediately sucked by the vacuum hose connected to the vacuum suction device. (4) When moving the lifting device to bring the device close to the surface to be processed, hit it in a state of accidentally hitting it. When you The shock absorber works to absorb the shock (5) Also, when the lifting device raises the entire surface of the caster of the device made up of the swivel caster until it touches the process surface, it is formed by the swivel caster and the work surface. When the moving surface of the device is not parallel, the universal joint attached to the center of the cradle that is integral with the shock absorber acts as a pivot so that the device is positioned parallel to the surface to be processed. Correction (6) The telescopic support leg attached to the tip of the universal joint is expanded and contracted by the lifting device of the support leg itself, and at the same time, by the spring or other load balancing mechanism provided inside. , XY table is positioned in proportion to the load applied from the table side (7) The support legs are integrally attached to the rotary table. Therefore, the positioning direction and position of the XY table with respect to the object to be processed can be changed by rotating the rotary table. (8) Since the rotary table is usually integrated with a pedestal equipped with a universal caster, the apparatus is processed. Can be installed at any position depending on the positional relationship with the surface (9) The device can be applied not only to the ceiling surface but also to the wall surface

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows a vacuum suction port 1 to which a vacuum hose connected to a vacuum device is connected, and a high-pressure water gun 3 having a brush 2 on the surface to be processed. . The high-pressure water gun 3 is usually equipped with a nozzle holder equipped with a nozzle, an air motor and an air hose for rotating the nozzle holder, a high-pressure water hose and swivel for supplying high-pressure water to the rotating nozzle holder, and a high-pressure water gun attached to the moving device.

Attach the high-pressure water gun 3 to the X and Y moving heads of the XY table 4 that moves orthogonally with the mounting bracket attached to the high-pressure water gun 3,
Flexible casters 5 (4 pieces) of equal length are attached to the four corners of the frame of the XY table 4. At four corners of the XY table 4 on the side opposite to the free casters 5, shock absorbers 6 (four pieces) and a pedestal 7 made of a plate that integrally receives the shock absorbers 6 are attached. (3) In FIG. 2, a universal joint 8 is attached to the center of the gantry 7, and a support leg 9 having a telescopic expansion / contraction mechanism and an elevating device 10 for the support leg 9 are installed at the tip of the universal joint 8. Inside the support leg 9, a mechanism for positioning by a compression spring 11 in balance with the load applied from the XY table 4 side is provided. The other end of the support leg 9 is installed and attached to a rotary table 13 on a pedestal 12 with casters. To be (4) When surface treatment of the surface to be treated using the product of the present invention, a high pressure water gun 3 connected to a predetermined hose or the like is attached to the X, Y moving heads of the XY table 4,
After allowing the X and Y orthogonal planes to move, the elevating device 10 of the support leg 9 is operated to move the XY table 4 to the casters 5.
Press until it touches the surface to be processed. At this time,
When a shock is generated by hitting the surface to be processed, the shock absorber 6 acts to absorb the shock. At the same time when the free caster 5 on the XY table 4 hits the surface to be treated, the universal joint 8 attached to the pedestal instantly acts like a rotary ball joint so that the moving surface of the high-pressure water gun 3 becomes parallel to the surface to be treated. The installation is completed in a very short time. Installed inside the support leg 9 in order to efficiently suck the splashed water from the high-pressure water gun 3, the falling water, and the waste material associated with the surface treatment to press the entire device against the surface to be processed to some extent to improve the vacuum suction effect. The compression action of the spring 11 is exerted. The pedestal 12 and the rotary table 13 are used for relative positioning with respect to the surface to be processed of the entire apparatus or for moving to the next surface treatment location.
