Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a cleaning device, and particularly to a cleaning device for cleaning pipes installed in high places.

[Background of the idea]

Conventionally, when cleaning dust on piping in high places, etc., a ladder or scaffolding is assembled near the piping. Dust on the piping is wiped off from the ladder or scaffolding using a chemical rag, rag, etc. However, such cleaning work is not only dangerous, but also requires time and effort to assemble ladders, scaffolding, etc. Further, there is a problem in that fine dust and the like are not absorbed by the chemical rag, but scatter or fall into the surrounding area and accumulate again on the pipes below.

[Purpose of invention]

The present invention was developed in view of these circumstances, and the purpose of the present invention is to propose a cleaning device that can safely and efficiently clean pipes installed in high places.

[Summary of the idea]

In order to achieve the above object, the present invention includes a curved pipe arranged along the outer peripheral surface of the pipe to be cleaned, and a notch along the axial direction in the pipe wall located inside the curved pipe while the inside of the curved pipe is sucked. A suction nozzle is formed, a brush mounting shaft bent into an arc shape and movably arranged in a curved pipe, a brush implanted in the brush mounting shaft and having a tip protruding from the suction nozzle of the curved pipe, and a brush mounting shaft. It is characterized by comprising a drive device that reciprocates the shaft within the curved pipe and brings the brush into sliding contact with the outer circumferential surface of the pipe to be cleaned.

〔Example〕

Preferred embodiments of the cleaning device according to the present invention will be described in detail below with reference to the accompanying drawings.

1 and 2 are a side view and a top view of a cleaning device according to the present invention. As shown in FIGS. 1 and 2, the cleaning device 10 includes a bent pipe 12 in which a suction nozzle is formed, a dust scraping brush 14, a drive device 16 for the brush 14, and a suction pipe 18. Ru. The suction pipe 18 has a length that reaches the piping 20 at a high place from the floor or the ground, and serves as an operating rod during cleaning. Further, as shown in FIG. 3, the suction pipe 18 is connected to a suction port 25 provided at the center of the curved pipe 12 via an expansion pipe 22 and an elbow pipe 24. The suction pipe 18 is connected to a suction pump on the floor (not shown), and the suction pipe suctions the inside of the curved pipe 12 via the suction pump 18, an expansion pipe 22, and an elbow pipe 24.

The bent pipe 12 is bent along the outer circumferential surface of the pipe 20 and is formed into a semicircular arc shape. As shown in FIG. 4, a suction nozzle 26 cut out along the axial direction is formed on the inner wall where the bent pipe 12 is bent. Further, a brush mounting shaft 28 bent into a semi-circular arc shape is inserted approximately at the center of the bent pipe 12 . The mounting shaft 28 is supported by support members 30A, 30B at both ends of the curved tube 12 and intermediate support members 32, 32 inside the curved tube 12, and is slidably disposed approximately in the center of the curved tube 12. The brushes 14 are installed on the brush mounting shaft 28 at predetermined intervals.
The tip is projected from the suction nozzle 26 and comes into sliding contact with the outer peripheral surface of the pipe 20.

The tip 28A of the brush mounting shaft 28 is partially inserted into the cylindrical support member 30A, and the base end 28A is inserted into the cylindrical support member 30A by a spring 36 provided in the support member 30A.
8B (in the direction of arrow A shown in FIG. 3). On the other hand, the base end 2 of the brush mounting shaft 28
A contact 38 inserted into the support member 30B is attached to 8B. The contact 38 has a spring receiver 4
0 is formed, and the support member 30B and the contact 38
A biasing force is applied in the direction of arrow B by a spring 42 provided between.

Further, the bent pipe 12 is connected to a drive device 16 via a cap nut 44 that is screwed into a male thread cut into the support member 30B, and the drive device is connected to a drive motor 46 and a motor shaft as shown in FIG. and a cam 48 attached thereto. The tip 38A of the contactor 38 is brought into contact with the cam 48, and the contactor 38 is reciprocated by the rotation of the cam 48 and the biasing forces of the springs 36 and 42. The reciprocating motion of the contactor 38 is transmitted to the brush mounting shaft 28, and the brush mounting shaft 28 is connected to the nozzle 12.
move back and forth within. As a result, the brush 14 comes into sliding contact with the surface of the pipe 20, and dust on the surface of the pipe 20 is scraped off. Incidentally, the bent pipe 12 is supported and fixed to the suction pipe 18 by a fitting 46.

In addition, as shown in FIG.
By removing it from 0B, the bent pipe 12 is removed from the drive device 16. Therefore, the bent pipe 12, the expansion pipe 22, and the elbow pipe 24
The section can be separated from the drive 16 and suction pipe 18 sections by loosening the thumbscrew 48 of the fitting 46. As a result, the curved pipes 12 with different curvatures
By replacing and using the pipes 20, it is possible to apply the pipes 20 to pipes 20 of different shapes, such as thick or thin pipes.

According to the cleaning device according to the present invention configured as described above, the curved pipe 12 is disposed on the upper surface of the pipe 20 at a high place from the ground or floor, with the base end of the suction pipe 18 serving as an operating rod. Next, dust is sucked in from the suction nozzle 26 by suctioning the inside of the curved pipe 12 with a suction pump. In this state,
The drive device 16 is driven, and the brush 14 is connected to the pipe 20.
sliding contact is made on the surface of Dust on the surface of the piping 20 is scraped up, sucked in through the suction nozzle 26, and removed. Since the dust on the piping 20 scraped off in this way is easily sucked in by the suction nozzle 26, the piping 20 can be safely and efficiently cleaned from the ground.

FIG. 6 is a side view showing a modification of the cleaning device according to the present invention. As shown in FIG. 6, axles 60, 60 are attached to the side surface of the bent pipe 12. In such a configuration, the bent pipe 12 is connected to the pipe 2 along the pipe.
It can be easily moved over 0. Further, by providing the axle 60, the distance between the suction nozzle 26 of the curved pipe 12 and the pipe 20 can be maintained at a constant distance, so cleaning can be performed uniformly and the tip of the brush 14 can be prevented from becoming sagging. It can be prevented.

[Effect of idea]

As explained above, according to the cleaning device according to the present invention, the sliding brush is provided in the curved pipe that is formed to match the outer peripheral shape of the pipe and has the suction nozzle. dust can be safely and efficiently cleaned.
