Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall cleaning device for cleaning a wall of a building having a gable-shaped roof, such as a greenhouse or a heated water pool.

[0002]

2. Description of the Related Art For example, in the case of a heated water pool, a building covering the pool is liable to disperse and cloud the transparent or translucent glass surface constituting the walls of the building due to chlorine used for disinfecting water. At least the inner surface of the glass surface needs to be cleaned at a pitch of 3 to 4 months.

[0003]

However, in the case of a heated water pool, the cleaning work of the transparent or translucent glass surface constituting the wall surface of the building, especially the canopy glass is a dangerous work at a high place. That is the current situation. In addition, when a worker performs cleaning work with a scaffold in a building, the user cannot use the heated water pool during that time, which causes inconvenience to the user. In addition, when a cleaning robot is inserted in place of a worker, it is necessary to be able to perform cleaning by straddling pillars and uneven portions of beams.

The present invention has been made in view of the above problems, and safely and efficiently cleans wall surfaces of a building having a gable-shaped roof, such as a greenhouse or a heated water pool, in particular, a canopy glass. It is an object of the present invention to provide a wall cleaning device which can perform the cleaning.

[0005]

That is, a first aspect of the present invention is a wall cleaning device for cleaning a wall surface of a building having a gable-shaped roof, comprising: a cleaning robot for cleaning the wall surface; A cleaning robot traveling rack attached to the inside of the adjacent steel frame material so as to face each other, a horizontal guide rail installed in the building, and a robot carrier cart traversably attached to the guide rail, The cleaning robot comprises a robot body, a traveling body attached to both sides of the robot body so as to be able to expand and contract in the lateral direction of the robot body, and a cleaning unit attached to the abdomen of the robot body so as to be able to move up and down via an extendable arm. The robot transport carriage is provided between the carriage main body traversing along the guide rails and the carriage so as to be movable up and down, and is cleaned between the steel frame members. A wall cleaning device is composed of a robot transfer platform for exchanging bot.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 2, reference numeral 1 denotes a total glass building having a gable roof 2, and a heated water pool 3 is installed therein. This building 1
It comprises a fixed building part 4 and a movable building part 5 which can slide in the longitudinal direction of the fixed building part 4.

During the summer, the movable building part 5 is stored in the fixed building part 4 so that swimming and the like can be enjoyed under the blue sky.
Outside summer, the movable building part 5 is pulled out of the fixed building part 4 so that swimming and the like can be enjoyed in the heated pool 3 in the building 1 fitted with glass. As shown in FIG. 1, the angled steel frame material 6 constituting the gable-shaped roof 2 in the fixed building part 4 and the movable building part 5 has an I-shaped cross section, and is provided on both lower flanges 7. Is provided with a cleaning robot traveling rack 8 over its entire length.

As shown in FIG. 1, the cleaning robot 20
A robot body 21 elongated in the lateral direction, that is, in the width direction of the steel frame material 6, and a traveling unit 22 disposed on both sides of the robot body 21 so as to be extendable and contractible in the longitudinal direction of the robot body.
And a cleaning unit 25 attached to the abdomen 23 of the robot body 21 via a telescopic arm 24 such as a fluid cylinder so as to be able to move up and down. The traveling portion 22 includes a pinion 26 that rides on the rack 8 and engages with the rack 8.
And a guide roller 27 that rolls in contact with the side surface 9 of the steel frame material 6.

The cleaning unit 25 is mainly composed of a box-shaped horizontally long cleaning head 29 having an opening 28 on the front surface, and a number of cleaning heads arranged in a horizontal line in the cleaning head 29 and rotationally driven by an electric motor (not shown). The brush 30 includes a brush 30 and a rubber squeegee 31 attached to a peripheral edge of the cleaning head 29 along the opening 28.

On the other hand, of the pillars 10 having the I-shaped cross section supporting the mountain-shaped steel members 6, the pillars 1 in the fixed building 4 are provided.
A horizontal guide rail 11 is attached to the inside of 0. A robot carrier 40 is attached to the guide rail 11 so as to freely traverse. The robot transport trolley 40 is provided with a trolley main body 41 traversing along the horizontal guide rail 11, and is provided on the trolley main body 41 so as to be able to move up and down, and exchanges the cleaning robot 20 with the steel frame material 6. And a table 42.

Next, the cleaning operation of the inner surface of the canopy glass of the building by the cleaning robot will be described. As shown in FIG. 3, among the mountain-shaped steel members 6 constituting the gable-shaped roof 2 of the building 1 covered with glass, the adjacent steel members 6, 6 are formed.
After the cleaning robot 20 is set in between, the cleaning unit 25 is raised in the direction of the arrow a to make contact with the roof glass of the building 1 (the inner surface of the canopy glass 12).

Next, while the cleaning brush 30 is being rotated while the cleaning liquid is being sprayed onto the inner surface of the canopy glass 12 from a nozzle (not shown), the pinion 26 of the traveling body 22 is rotated forward. Go in the direction of. Then, dirt and impurities on the inner surface of the canopy glass 12 are rubbed by the cleaning brush 30, and the inner surface of the canopy glass 12 is cleaned neatly by the wiping action of the rubber squeegee 31 accompanying the forward movement of the cleaning robot 20.

The cleaning liquid sprayed on the inner surface of the canopy glass 12 is recovered from the cleaning head 29 by the suction action of a vacuum pump (not shown), and is separated into water and water in a tank (not shown). The cleaning water is pressurized by a pump (not shown), filtered by a filter (not shown), and used for circulation. The cleaning unit 20 is connected to the cross beam 13 (FIG. 4).
(See Reference), the cleaning operation by the cleaning unit 25 is temporarily stopped, and the cleaning unit 25 is lowered by the telescopic arm 24 in the direction of arrow c. During that time, the cleaning robot 20 keeps moving forward, so that when the cleaning unit 25 has passed over the cross beam 13, the cleaning unit 25 is raised again in the direction of arrow a to contact the inner surface of the canopy glass 12 and the cleaning brush The cleaning by 30 is restarted.

When the cleaning robot 20 reaches the uppermost portion of the steel frame material 6, the cleaning robot 25 is lowered in the direction of arrow c, and the cleaning robot 20 is retracted to just above the robot carrier 40. Next, after raising the robot transfer table 42 of the robot transport trolley 40 from the trolley body 41 to support the cleaning robot 20, the traveling body 22 of the cleaning robot 20 is contracted, and the pinion 26 of the traveling body 22 is racked with the steel frame 6. Remove from 8. Next, the robot transfer table 42 is lowered onto the carriage main body 41 of the robot transfer carriage 40.

Next, the robot carrier 40 is traversed by one pitch, and is moved between the adjacent columns 10 and 10. And
After raising the robot table 40 above the lower flange 7 of the steel member 6, the left and right traveling bodies 22 of the cleaning robot 20 are moved.
Is extended. Next, the robot transfer table 42 is slightly lowered, and the pinion 2 of the traveling body 22 of the cleaning robot 20 is placed on the rack 8 provided on the lower flange 7 of the steel frame 6.
6 is engaged. Then, as described above, after the cleaning unit 25 is started, the traveling body 22 is started, and the building 1 is started.
Of the canopy glass 12 is cleaned. Meanwhile, the robot carrier 40 moves the robot transfer table 42 to the carriage body 4.
1 and stand by while being lowered.

The cleaning robot 20 is automatically operated by computer control, but can be remotely operated.
The vertical glass surface of the building 1 is cleaned by a known hanging-type cleaning robot 50.
