Description

[Detailed description of the invention] [Technical field to which the invention pertains] The present invention relates to a cleaning machine, and more particularly, to a cleaning machine that includes a rotating brush and performs cleaning or polishing work with the rotating brush.

[Background Art] Conventionally, cleaning machines equipped with rotating brushes rotated by electric drive motors have been known, but when cleaning oil tanks, ship tanks, etc., or polishing floorboards, flammable Because flammable gases and liquids may be present, the use of electric drive motors, which can serve as a source of ignition for these flammable gases, is extremely dangerous. For this reason, cleaning and polishing work had to be done directly by hand using brushes, cloths, etc., but this work was extremely inefficient and required long hours of work.Moreover, such an environment was harmful to the human body. Due to the nature of the environment, workers were forced to work in a hazardous environment for long periods of time, posing health management issues.

[Purpose of the invention] The purpose of the invention is to provide a cleaning machine that can perform safe cleaning work even in an environment where flammable gas, toxic gas, etc. are present.

[Structure of the invention] Therefore, the present invention includes an air-driven motor and a rotary brush rotated by the air-driven motor attached to the distal end side of a handle having a gripping portion on the proximal end side.
The air-driven motor does not generate sparks that can become a source of ignition, making it possible to carry out cleaning work safely.In addition, a branch pipe is installed in the middle of the air supply pipe that supplies air to the air-driven motor, making it easier for workers to clean. By connecting an air mask to ensure breathing air, the worker can breathe in toxic gases in the working environment, thereby achieving the above objective.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described with

The figure shows an embodiment of the cleaning machine according to the present invention, and in the figure, a handle 2 is provided on the base end side of a handle 1 made of a round shaft tube of a predetermined length. A base 3 is fixed to the tip of the handle 1, and an air drive motor 4 is fixed to the center of the upper end surface of the base 3 with its output shaft facing downward. Also,
A rotary brush 6 is rotatably supported on the lower end surface side of the base 3 via a rotary disk 5, and this rotary brush 6 is fixed to the output shaft of the drive motor 4, so that the rotary brush 6 is connected to the air drive motor. It is configured to be rotated by more than 4 degrees.

An exhaust pipe 7 is connected to the air drive motor 4, and an air supply pipe 8 is also connected thereto. A lubricator 9 and a pressure adjustment lever 11 are provided in the middle of the air supply pipe 8, and by operating this lever 11, the air pressure applied to the motor 4 from an air pressure source (not shown) via the air supply pipe 8 is adjusted. The rotation brush 6 can be adjusted to rotate at a desired rotation speed.

Further, a manifold (branch pipe) 12 is attached to a predetermined position of the air supply pipe 8, and an air mask 14 is connected to this manifold 12 via a mask pipe 13.

According to this embodiment, since the rotary brush 6 is rotated by the air-driven motor 4, it can be used, for example, in cleaning prior to inspection when opening a crude oil tank, heavy oil tank, etc.
Even in dangerous environments where flammable gases or liquids are present, there is no risk of generating sparks that can become a source of ignition, making cleaning work extremely safe.

In addition, since a part of the air supplied to the air drive motor 4 can be used for the air mask 14,
It is convenient because cleaning work can be carried out without harming health even in places where the work environment is extremely bad for the human body, such as in the presence of toxic gas.

In addition, since the air drive motor 4 is extremely lightweight compared to an electric drive motor, it has excellent operability during cleaning work, and the rotation speed of the rotary brush 6 can be easily changed by adjusting the pressure adjustment lever 11. Able to perform appropriate work according to cleaning purpose.

Furthermore, it is lightweight and convenient not only during cleaning work but also during transportation.

In addition, when implementing the air mask 14, the air mask 14 is not limited to one formed to cover almost the entire face as in the above embodiment, but may be a helmet-type one that covers the entire head, or may be formed to cover the entire head. The air mask is not limited to one that has one, and may be one that simply covers the nose and mouth.In short, an air mask that can supply the air necessary for the worker to breathe is used. Further, although the pressure adjustment lever 11 is not necessarily required, it is convenient to have the pressure adjustment lever 11 because the rotation speed of the rotary brush 6 can be adjusted.

[Effects of the invention] As described above, according to the invention, sparks that become a source of ignition are not generated, the air mask allows workers to breathe, and flammable gases, toxic gases, etc. It is possible to provide a cleaning machine that can perform safe cleaning work even in environments where
