Abstract

PURPOSE:To facilitate the cleaning work by fixing a pair of gondola supporting arms on the upper part of a building, and providing lateral ropes suspended from the gondola supporting arms and the gondola body for work. CONSTITUTION:The gondola for work is formed of a pair of gondola support arms 1 fixed to the top part of the building 2, lateral ropes 17 suspended from the gondola supporting arms 1, and a working gondola body 18. The working gondola body 18 has a gondola frame 23 allowing a worker to get on the gondola body 18 and a movable arm on which a pair of guide rollers 27 for guiding the lateral ropes 17 in cross. When the working gondola body 18 is laterally moved, a pair of vertical moving devices are operated so that the upper lengths of the lateral ropes 17 are mutually differed to laterally move the gondola body 18. Thus, a cleaning work can be safely done.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work gondola used for cleaning windows of buildings such as buildings.

[0002]

2. Description of the Related Art Conventionally, a work gondola of this type has a pair of left and right ropes suspended from a pair of gondola support arms fixed to portions near both upper ends of a building such as a building by the present inventor. A structure in which a gondola main body on which a worker can ride is moved in the vertical and horizontal directions is considered.

[0003]

A conventional work gondola capable of moving the gondola body vertically and horizontally has a guide member for guiding the left and right ropes at the upper part of the gondola body. When the main body is moved left and right, the gondola main body is inclined due to the pulling force of the left and right ropes, and there is a drawback that it is not possible to safely perform window glass cleaning work.

In view of the above-mentioned conventional drawbacks, the present invention has been made.
Even if the gondola body is moved in the left-right direction, the gondola body is always in the vertical state, so that the window glass can be cleaned safely and efficiently, and the structure is simple and inexpensive to manufacture. It is intended to provide a working gondola.

The above and other objects and novel characteristics of the present invention will become more fully apparent when the following description is read in view of the accompanying drawings. However, the drawings are for explanation only and do not limit the scope of the present invention.

[0006]

In order to achieve the above object, the present invention relates to a pair of gondola support arms fixed to a portion near both upper ends of a building such as a building or a portion separated by several meters, and the pair of gondola supporting arms. The left and right ropes suspended from the gondola support arm of the vehicle and the operators who can expand and contract the lengths of the left and right ropes and move vertically and horizontally to clean the window glass etc. In a work gondola including a work gondola body capable of moving, a gondola frame on which the worker can ride the work gondola body, and a tip attached to substantially the center of the gondola frame so as to be rotatable in the left-right direction. The movable arm with a pair of guide rollers attached to the left and right ropes to guide the left and right ropes, and above the gondola frame. The side guide rollers for guiding the left and right ropes from the pair of guide rollers of the movable arm attached to both sides downward and the left and right ropes for the side guide rollers attached to the gondola frame are respectively expanded and contracted. A work gondola is composed of a pair of rope up-and-down moving devices such as an electric winch and winder.

[0007]

In the work gondola constructed as described above, the work gondola main body moves in the vertical direction by actuating a pair of rope up-and-down moving devices to expand and contract the left and right ropes in the same manner. Further, the work gondola main body moves in the left-right direction by expanding and contracting so that the lengths of the left and right ropes are different. At this time, since the movable arm to which the pair of guide rollers is attached is rotated in the left-right direction, the gondola frame on which the operator rides is always kept in the vertical state.
