Abstract

PURPOSE:To facilitate the lateral movement of a working gondola by changing the gondola suspending position by supporting the lateral ropes for suspending the working gondola by rope support arms provided on one side of a building roof, or removing the ropes therefrom. CONSTITUTION:The right rope 15 is fixed to the right support arm 9 of the right-hand end part rope support member 1. The left rope 14 is supported by the left arm 9 of the adjacent rope support member 13, and also fixed to the left arm 9 of the left-hand support member 1 through the arm 9 of the other support member 13. The ropes 14, 15 are driven by the electric winches 23, 24 of a gondola body 16, and the body 16 is vertically and laterally moved to clean windowpanes. In the movement to the left, the body 16 is situated just under the left-hand support member 13, the rope 15 is stretched by the winch 24 after the rope 15 is loosened and supported by the right arm 9 of the support member 13. Further, the rope 14 is loosened by the winch 23, and removed from the left arm 9. Thus, the body 19 can be easily and efficiency moved, and the structure can be also simplified.

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 In a conventional work gondola, a gondola main body having left and right electric winches at both ends on which a person can ride and a tip of left and right ropes wound around the left and right electric winches of the gondola are fixed It is composed of a plurality of rope fixing arms which are fixed to the roof of a building or the like with the width of the gondola main body and project outward from the building.

[0003]

In the conventional work gondola, the tips of the left and right ropes wound around the left and right electric winches of the gondola body are fixed to adjacent rope fixing arms fixed to the roof of the building. Operate the left and right electric winches and move the gondola body up and down to clean the window glass. After that, lower the gondola body to the ground, replace the ends of the left and right ropes with the adjacent rope fixing arms, operate the left and right electric winches and move them up and down to clean the adjacent window glass. I'm working. For this reason, it is necessary to lower the gondola body to the ground when cleaning the window glass on one side of a building such as a building, and to replace the ends of the left and right ropes with rope fixing arms, which is troublesome and efficient. There was a drawback that it was not possible to carry out the cleaning work.

In view of the above-mentioned conventional drawbacks, the present invention has been made.
Without lowering the work gondola main body to the ground, the left and right ropes are supported by the rope support part of the adjacent rope support member, and the adjacent window glass is moved up and down in order to efficiently and quickly change the position. The purpose is to provide a work gondola that can be performed.

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 is a rope in which a rope fixed to one end of one side of a roof of a building or the like is fixedly locked. A pair of end rope support members each having an end rope support arm projecting outward from one side surface of the building with the locking portion formed at the tip, and a predetermined roof top between the pair of end rope support members. A plurality of rope supporting members each having a pair of rope supporting arms, each of which has a pair of rope supporting arms formed at a tip end thereof, on which ropes fixed at intervals are detachably supported, and a rope of which one end is the pair of end rope supporting members. Left and right that are respectively locked to the locking portions and the other end is selectively supported by the rope supporting portions of the plurality of rope supporting members, and can be hung from the rope supporting portion near the other end to the ground portion. And the rope of this The work gondola is composed of a work gondola body with left and right electric winches that can be carried by people so that they can wind or wind up and down and move them up and down or left and right to clean the window glass. There is.

[0007]

With the work gondola configured as described above, the left and right electric winches are actuated to move the work gondola body left and right while moving up and down to perform window glass cleaning work, etc. The gondola body is located at the top so that it is located near the rope support member,
A rope which is not supported by the rope supporting portions of the pair of rope supporting arms of the rope supporting member is supported by the rope supporting portion, and the rope supported by the rope supporting portion is removed from the rope supporting portion, so that the adjacent portion rope The work gondola body can be moved in the vertical and horizontal directions so that the window glass between the support members can be cleaned.
