Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for safely and efficiently cleaning the walls of buildings and tunnels.

[0002]

2. Description of the Related Art Conventionally, in order to clean a wall surface of a building, a worker rides on a gondola that moves up and down along the wall surface of the building and uses an electric brush or a deck brush and a cleaning agent. To clean the wall surface in the tunnel, as shown in FIG. 10, the rotary brush (4
The cleaning device provided with 2) was mounted on the work vehicle (43) for use. In this cleaning device, the rotating brush (42) is moved along the wall surface (33) of the tunnel (32) into the arm (4).
It is designed to be raised and lowered in 1).

[0003]

Since the conventional cleaning of the building wall surface is carried out manually by the worker, not only is it very inefficient and the labor cost is increased, but also the possibility of a fall accident of the worker is caused. There was always the problem of being stuck. Although it is conceivable to wash the wall surface of the building using a rotary brush (42) similar to the wall surface (33) of the tunnel (32) described above, this rotary brush (42) cleans the cleaning liquid and contaminated water around it. Since it scatters on the ground, it has a great impact on the surrounding environment when it is carried out at a height of several meters to a dozen meters, and it cannot be used for cleaning the wall of a building.

Further, when the wall surface (33) in the tunnel (32) is cleaned by the above-described vehicle-mounted cleaning device, the rotary brush (42) is attached to the tip of the arm (41). The operating range was limited. That is,
From the lowermost portion (44) of the substantially linear side wall surface to the uppermost portion (45) of the arc-shaped ceiling surface, all of the rotary brushes (4
There was a problem in that it could not be washed in 2).
Further, since the inside of the tunnel (32) has little influence on the surrounding environment, the cleaning liquid and the polluted water are still scattered, and the worker bathes the scattered cleaning liquid and the polluted water from the head, and , There was a problem that I had to work while sucking.

According to the present invention, in the above-described cleaning of the wall surface, the human labor is minimized, and even if the cleaning is performed with a large rotating brush, the cleaning liquid polluted water does not scatter, and further, the danger is raised to a high place. The purpose is to obtain a wall surface cleaning device that does not require the arrangement of workers.

[0006]

The present invention has been made in order to solve the above problems. As a first means, a guide rail is installed on a wall surface of a building, and a rotary brush driven by a motor is installed. Only the wall surface of the building is pivotally supported in an open gondola, and sealing pieces are provided at the top, bottom, left and right of the open surface of this gondola, and at the bottom there are means for collecting polluted water and means for draining the collected polluted water to the ground. A guide wheel that travels along the guide rail is provided outside the gondola, a winch that raises and lowers the gondola while suspending it with a wire on a ground work vehicle, and a means for supplying water and cleaning liquid to a rotating brush of the gondola. And a tank containing water for cleaning and a cleaning liquid.

As a second means, a guide rail is installed from the upper part of the work vehicle to the lower part of one side surface, and a polluted water scattering prevention means is provided below the guide rail, and a rotary brush driven by a motor is installed. Is supported in a gondola, and a guide wheel that travels along the guide rail is provided in the gondola, and a winch that raises and lowers the gondola while suspending it with a wire is attached to the work vehicle, and water is applied to a rotating brush in the gondola. And means for supplying the cleaning liquid, and a tank for storing the cleaning water and the cleaning liquid.

[0008]

In the first means, the gondola is washed up to the top of the wall surface of the building with a winch, and the means for supplying water and the cleaning liquid is operated to remove the water and the cleaning agent tank mounted on the work vehicle from the tank on the gondola. When the rotating brush is rotated while supplying water and the cleaning agent to the rotating brush, the building wall surface is cleaned. Then, loosen the winch and pull down the wire at an appropriate speed to lower the gondola. The water and the cleaning agent used for cleaning become polluted water containing dirt, and are drained to the ground via the drainage means via the polluted water collecting means at the bottom of the gondola. At this time, the sealing piece on the lower side of the gondola descends while contacting the wall surface of the building, so that the polluted water that falls is scooped down and flows down to the bottom of the gondola.

In the second means, the means for supplying water and the cleaning liquid are operated to rotate the rotary brush while supplying the water and the cleaning agent from the tank of the water and the cleaning agent on the work vehicle to the rotary brush. Let Then, wind the wire around the winch,
Alternatively, while pulling out, raise or lower the gondola at an appropriate speed. Then the walls of the tunnel are washed,
The polluted water containing the cleaning agent and the dirt falls through the polluted water scattering prevention means to the roadside, and is drained to the sewer through the gutter or the like.
