The chimney 1 is a tower-like structure having a circular cross section, and has a general shape in which a base (root) has a large diameter and is gradually reduced toward the top. . On the outer wall of the chimney 1, a plurality of gondola 2 are suspended and raised and lowered. In this embodiment, six gondola 2 are arranged on the outer periphery of the chimney 1 so as to surround it. Have been. A scaffold plate 3 is provided between the respective gondola 2 so that the whole is integrally connected.

The work gondola apparatus is to be suspended along the outer wall of the building to serve as a scaffold for various kinds of work at high altitudes. Each gondola 2 is provided with a drive mechanism 4 for expanding and contracting the scaffold plate 3, and the distance between the gondola 2 is changed following the vertical movement. It is configured.

Each gondola 2 has a substantially pentagonal base plate 20 as shown in FIGS.
The frame body 21 is assembled on the top 0, and is an independent unit. On the other hand, the scaffold plate 3 passed between the adjacent gondola 2 is formed by joining two slide plates 30, and the length of the slide plate 30 is set to a predetermined length that fits on one side of the base plate 20. And the base plate 2
0 is attached to a guide portion provided so as to guide its movement. On the base plate 20 and the slide plate 30 constituting the scaffold plate 3 of the gondola 2, fences 22 and 32 for safety are erected at respective edges. In addition,
FIGS. 3A and 4A show an embodiment at the top of the chimney, and FIGS. 3B and 4B show an embodiment at the lower portion of the chimney.

On the base plate 20 of the gondola 2, a drive motor 40 is provided substantially at the center thereof. On the back side of the base plate 20 below the drive motor 40, as shown in FIG.
1 is provided, and the driving force of the driving motor 40 is transmitted to the driving shaft 41 via the chain 42. The slide plate 3 is provided on both sides of the drive shaft 41.
0, feed screws 43, 43 are provided, and the rotation of the drive shaft 41 is transmitted by meshing of bevel gears provided at the tip of each shaft. And
A slide piece 44 having a corresponding screw hole is meshed with each feed screw 43, and the slide piece 44 is fixed to the front end of the slide plate 30. For this reason,
With the rotation of the drive shaft 41, both the feed screws 43, 43 rotate, and on each feed screw 43, the slide piece 44 moves in the axial direction due to the engagement thereof,
Therefore, the slide plate 30 to which the slide piece 44 is fixed is
Will be moved in its longitudinal direction. That is, the above-described configuration connected to the slide plate 30 using the drive motor 40 as a drive source becomes the drive mechanism 4, and the drive motor 4
The scaffold 3 is extended or contracted in response to the normal rotation / reverse rotation of 0.

As described above, in the gondola device, a plurality of gondola 2 are arranged on the outer periphery of the chimney 1, and the scaffold plate 3 is passed between the gondola 2 and is integrally connected as a whole. This is a ring-shaped scaffold that goes around the chimney 1. Further, since the scaffold plate 3 is expanded and contracted by the drive mechanism 4, the scaffold plate 3 can be expanded and contracted in accordance with the mutual interval between the gondola 2.
At the top of the chimney, the entire outer diameter can be reduced by contracting as shown in each figure (A), and conversely, at the base of the chimney 1, it can be expanded as shown in each figure (B) to reduce the entire outer diameter. The diameter can be enlarged. That is, the distance between the gondola 2... Can be changed following the up-and-down movement. The ring-shaped configuration of the device does not hinder the up-and-down movement, and corresponds to the change in the external form of the chimney 1. It is safe because the interval facing the outer periphery of the chimney 1 can be appropriately maintained.
Therefore, it is unnecessary to change the gondola as in the related art, and the workability is excellent, which is advantageous for labor saving.
