Description

[Detailed description of the invention] Industrial application field This invention relates to a pipe cleaner used for removing clogging and scale adhering to pipe walls in pipes of different diameters such as sewer pipes and drainage pipes.

BACKGROUND ART Conventionally, as this type of device, one shown in FIG. 8 has been widely used.

In the figure, reference numeral 1 denotes a frame, and a house 9 having a tubular neck portion 8 is rotatably provided on a bearing portion 2 provided on the frame 1. Reference numeral 10 denotes a shaft portion of the house 9, which is fixed to the house 9 and is provided with a handle 11. 3 is a flexible shaft, and when not in use, most of its portion is accommodated in the house 9 while being elastically deformed into a circular shape. Reference numeral 5 denotes a tip tool provided at the tip portion 4, and a wire head is provided as an example.
12 is a chuck, and by using this chuck 12, the neck portion 8 and the flexible shaft 3 are integrally fixed.

In the pipe cleaner formed in this way, the flexible shaft 3 is inserted into a pipe (not shown) to be cleaned, and if there is a clogged part in the pipe, the tip tool 5 is used to break it up or the tip is removed. It is cleaned by wrapping it around the tool 5 and collecting it. When rotating the flexible shaft 3, the flexible shaft 3 and the neck 8 of the house 9 are fixed together using the chuck 12, and the house 9 is rotated using the handle 11.

Problems to be Solved by the Invention However, the above-mentioned conventional device has the following drawbacks. For example, when cleaning drain pipes in buildings, the size of the drain pipes is not uniform, and pipes of various sizes are connected and installed, so it is difficult to clean the drain pipes of various sizes. The flexible shaft 3 and each tip tool 5 used for each flexible shaft 3 must be prepared. These are then carried to the upper part of the building.

However, it is troublesome to prepare and transport flexible shafts of various thicknesses and tip tools to be attached to them. Furthermore, conventional tip tools can only clean the size of the tool; for example, even if a tool with a diameter of 40 mm is inserted into a pipe with an inner diameter of 100 mm, scale cannot be removed from the inner surface of the pipe. Naturally, if you use a tip tool with a diameter of 100 mm, you cannot insert it into a pipe with an inner diameter of 40 mm. This invention was made to solve these problems, and its purpose was to eliminate the trouble of preparing and transporting various flexible shafts and the tip tools used for them, as in the conventional method, and to create a single type of flexible shaft. To provide a pipe cleaner capable of cleaning all pipes having different diameters using a flexible shaft and a tip tool used therefor.

Means for Solving the Problems To describe this invention that achieves the above object, it consists of a flexible shaft 3 that is rotatably supported indirectly or directly on the bearing part 2 of the frame 1; Tip tool 5 provided in section 4; flexible shaft 3
This pipe cleaner comprises a side tool 6 having elasticity and rigidity, which is provided behind the tip tool 5 and protrudes laterally. Furthermore, the side tool 6 is the pipe cleaner formed of wire rope. Furthermore, the side tool 6 is the pipe cleaner detachably provided on the flexible shaft 3.

Operation First, the flexible shafts 3' and 3 of the pipe cleaner configured as described above are inserted into a thin pipe. In that case, the side tool 6 is removed and only the tip tool 5 is used and inserted into the pipe. If the pipe is clogged, it is cleaned using the tip tool 5. Also, if necessary, the flexible shaft 3 is rotated and cleaned. Next, when this flexible shaft 3 is to be inserted into a medium or thick pipe, a side tool 6 is attached to the flexible shaft 3 and inserted into the pipe. Then, the side tool 6 comes into pressure contact with the inner surface of the pipe while being elastically deformed,
By rotating the flexible shaft 3, the side tool 6 cleans the clogged pipe.

In this way, the middle of a thin pipe or all of a thick pipe can be inserted by one type of flexible shaft 3.

Embodiment In FIGS. 1 and 2, 1 is a frame, and a neck 8 of a house 9 is pivotally supported by a bearing 2 provided on the frame. It also pivotally supports the shaft portion 10 of the house 9. Since many parts of this invention are formed the same as those of the conventional device, the same parts as the conventional device will be described with the same reference numerals. 1
1 rotates the shaft portion 10 with a handle. 3 is a flexible shaft, 4 is a tip, and 5 is a tip tool, which is formed to be replaceable with a wire head, a spear-shaped head, and various other types. Next, 6 is a side tool, and a wire rope was used as an example. The tool 6 is attached to a holding member 14 fixed to the flexible shaft 3 as shown in FIG.
It is set in. 15 is solder, 16 is head,
17 is a holding hole, 18 is a fixing screw, and a screw groove 19
It is screwed together. In addition, in Figure 1, 12
is a check.

As shown in FIG. 3, the side tool 6 is provided in a removable manner.

Further, as an example, two of the same tools 6 are installed in 180 degrees different directions. Further, the end 20 is fixed by solder, for example. Further, as the tool 6, a stainless steel wire rope was used as an example. 21 indicates a connecting portion.

This pipe cleaner is used as described in the above section of the function, and the one shown in Figs. 4 and 5 is used for a medium-sized pipe with an inner diameter of 40 mm, as an example. The ones shown in Figures 6 and 7 are used for a thick pipe with an inner diameter of 100 mm, and in both cases, the side tool 6 rotates while being in pressure contact with the inner surface of the pipe, and is pushed forward to make the eye. This is to clean out clogs, scale, etc. Note that FIGS. 4 and 6 show the progress state, respectively, and FIGS. 5 and 7 show the return state, respectively.

Effects of the invention This invention is constructed as described above, and the tip portion 4 of the flexible shaft 3 is formed to be freely rotatable.
A tip tool 5 is provided on the flexible shaft 3, and a side tool 6 having elasticity and rigidity is provided which protrudes laterally behind the tip tool 4 of the flexible shaft 3, so that pipes with various inner diameters can be used. can all be cleaned with one pipe cleaner.
