Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is for suspending or rewinding a rope member by suspending it from a suspending device provided on the upper portion of the building through a rope member in proximity to the outer wall surface of the building. The present invention relates to a structure of a cage for a gondola device which is vertically driven along an outer wall surface of a building by a lifting device that moves.

[0002]

2. Description of the Related Art For a work such as cleaning of an outer wall surface of a building, a gondola device in which a cage is hung from a hanging device provided on the upper part of the building through a wire rope is used.

As such a gondola device, a permanent device called a so-called main gondola is known. This involves laying rails around the outer wall of the building around the rooftop, and providing a trolley running on the rails with a suspending device equipped with an arm projecting outward from the outer wall of the building. It is configured by suspending a cage with a wire rope via an arm. A lifting device that can wind and rewind the wire rope is provided in the hanging device.
The cage is driven up and down by winding or unwinding the wire rope by the lifting device.

By the way, the work on the outer wall surface of the building may be performed manually by an operator who has entered the cage depending on its content, or may be automatically performed by a work robot provided in the cage. Although sometimes possible, the conventional permanent gondola device described above copes with this by exchanging the cage portion when different work is required for the outer wall surface of the building. For example, when the worker switches to cleaning by an automatic machine such as an automatic cleaning unit after performing the manual work, the cage is replaced with the automatic cleaning unit to perform the work. To replace the cage, lift the cage to the roof by the lifting device, move the dolly to the cage storage location, lower the cage into place, remove the wire rope, and then store the cage in another storage location. It is done by connecting it to a cage and lifting this gauge to return the dolly to its working position.

[0005]

However, the above-mentioned cage replacement is time-consuming and troublesome because the cage is replaced after the carriage is moved to a cage storage location different from the normal working location. However, there was a possibility that mistakes might occur in the replacement work, and there was a problem in safety.

The present invention has been made in order to solve the above problems, and provides a cage for a gondola device which can easily and safely convert its function in a short time when performing different wall surface works. It is what

[0007]

A cage for a gondola device of the present invention that achieves the above object is provided from a suspending device provided at the upper part of a building in the vicinity of an outer wall surface of the building through a rope member. A cage for a gondola that is suspended and is driven up and down along the outer wall surface of a building by a lifting device that winds or unwinds the rope member, and the cage base to which the rope member is coupled has a plurality of different functions. A rotating unit having a functional unit is rotatably supported via a rotating mechanism, and one of the plurality of functional units is alternatively configured to face the outer wall surface of the building by rotation of the rotating unit. .

[0008]

When switching to a different work, the rotating mechanism rotates the rotating portion with respect to the cage base, so that the desired functional portion of the plurality of functional portions provided on the rotating portion becomes the outer wall surface of the building. The positions are opposite to each other. As a result, it becomes possible to perform wall surface work by the functional unit.
