Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning device for cleaning the inner wall surface of a cylinder of a chimney made of steel, for example.

[0002]

2. Description of the Related Art Generally, deposits such as floating rust and soot adhere to the inner wall surface of a cylinder of a steel chimney due to use, and it is necessary to clean and remove it regularly.

By the way, conventionally, when cleaning the inner wall surface of the chimney, an operator rides on an elevator (hereinafter referred to as a "gondola") provided for maintenance of the chimney, while sequentially raising and lowering the gondola. A worker manually uses a brush to cover the entire inner wall surface of the chimney.

[0004]

As described above, it is very heavy labor for the operator to manually clean the entire inner wall surface of the cylinder of the chimney by hand using a brush. Since the deposits removed from the inner wall surface of the barrel scatter, work in such an environment is unsanitary, and this work is performed at a high place in the chimney, which poses a problem that it is dangerous.

Therefore, an object of the present invention is to provide a chimney cleaning device that can solve the above problems.

[0006]

Means for solving the problems of the present invention is to provide a cleaning brush which is driven to rotate by abutting on the inner wall surface of the cylinder of the chimney, in the outer peripheral portion of the mounting base through a support shaft. A weight that is attached to one side of a support frame that is rotatably attached and that urges the cleaning brush toward the inner wall surface of the barrel is provided on the other side of the support frame.

Further, a cleaning brush is attached via an urging means for urging the cleaning brush toward the inner wall surface of the barrel, and the adjacent mounting bases are rotated in opposite directions about the vertical center axis of the elevating column. A swivel device is provided.

[0008]

In the above means for solving the problems, the weight of the weight attached to the other side of the support frame acts on the cleaning brush attached to one side via the support shaft supporting the support frame, and the cleaning brush is the cylinder of the chimney. The cleaning brush is rotated by being urged into contact with the inner wall surface of the body, and the cleaning brush is rotated to remove the adhering matter adhering to the inner wall surface of the cylinder of the chimney and automatically clean it.

Further, the cleaning brush is urged toward the inner wall surface of the barrel by the urging means, the slewing device is driven, and the adjacent mounts are swung in the opposite directions about the vertical center axis of the elevating column. Remove the deposits on the inner wall of the chimney barrel,
Clean automatically.
