Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a self-propelled scaffold for window cleaning work.

(Prior art) For example, as a scaffold for cleaning windows of high-rise buildings on land,
Conventionally, a gondola was suspended via an A cable from a dapit cart that was installed on the shore and could be moved laterally, and the steel cable was wound around the gondola using a winch.
There are known devices that can be raised and lowered by being extended.

However, such a device has the following drawbacks.

(1) Because the gondola's restraint is insufficient, it sways when the wind is strong, making it impossible for workers to clean the windows, and even more so when they are used for cleaning the windows of ships that are shaken by the waves. It is simply impossible to do so.

(2) Since the main focus is on versatility, adjustment operations require time and effort, and therefore it takes time to get the gondola ready for the confectioners to board.

(3) Since the dapit cart is moved by indirect operation on a non-special electric pole, its movement is slow, and therefore it takes time for the worker in the gondola to reach the If+ electric position.

[08J to be solved by the invention] The non-explosion was proposed in view of the above 11 circumstances.
The purpose is to provide self-propelled scaffolding for window cleaning work that is both safe and efficient. [Means for Solving the Problems] To this end, the present invention provides a relatively large rectangular doorway opened in the outer cabinet, and a rectangular doorway pivoted on the inner side of the doorway to open the doorway from the indoor side. and l pairs of upper and lower dapits pivotally mounted on the other side of the inner surface of the entrance, and a dapit upper rail and a dapit lower rail attached horizontally to the dapits, each supported via a roller and having built-in braking and manual means. a self-driving gondola having a relatively small rectangular vertical cross section; an upper rail and a lower rail attached to the upper and lower ends of the glass window on the outer surface of the outer wall and located at the same level as the dapit upper rail and the dapit lower rail, respectively; The automatic gondola is equipped with an illumination source cord and a reel for a water supply hose attached to the automatic gondola, and allows the automatic gondola to be moved in and out of the outer wall through the dapit and the entrance, and the upper rail on the outer surface of the outer wall. It is characterized by being able to move along the lower rail.

[Effect]

The automatic gondola is supported via rollers on the dapit upper rail and dapit lower rail attached to the dapit pivotally attached to the entrance/exit, making it easy to store the automatic gondola into the room. In addition, since the automatic gondola is equipped with both braking and manual means, it will not be shaken or become unable to move.

Furthermore, when the automatic gondola is rotated to the entrance/exit position by the dapit, the dapit upper rail and the dapit lower rail are aligned with the upper and lower rails attached to the upper and lower sides of the exterior glass window, respectively, so the automatic gondola is rotated to the entrance/exit position. It can be moved laterally along the glass window rail via the side rail.

And 1 for the automatic gondola! Since a reel for the line water supply hose is attached, power and water can be supplied despite horizontal movement, and the line and hose can be easily handled.
