Description

  The present invention relates to a kelen device that mainly removes rust such as exposed bolts and nuts thereof, and more particularly to a kelen device that is rotationally driven by a rotating device.

  The term “Kelen” is generally used mainly as a pretreatment work for rust-proof coating. According to the Japan Road Association's “Handbook for Steel Road Bridge Painting”, It is used to mean “base adjustment”. This substrate preparation is classified into 1 to 4 types. For example, in the case of 4 types of keren, the state of the treated surface is “removal of old paint film, chalking only, removing powder and dirt with a wire brush” In this case, the processing method is “wire brush or the like”.

  For example, a folded plate roof as shown in FIG. 1 is fixed to the lower steel structure material using bolts and nuts. Generally, these bolts and nuts are located on the upper side of the folded plate roof. Remains exposed. Since such exposed bolts and nuts are easily rusted by being exposed to wind and rain, "maintenance" or "replacement" described above is required when performing maintenance or replacement.

  As a device for performing such “rust removal”, that is, “keren”, there is a “rotating wire brush” as proposed in Patent Document 1.

Public Open Hei 6-66363 Publicity, Summary, Representative Map

  The “Rotating Wire Brush” proposed in Patent Document 1 is “cleaning a desired part by simply holding it without moving your hand, and cleaning multiple surfaces at once. The time is shortened, the fatigue of the worker can be greatly reduced, and the consumable is provided with an economical rotating wire brush that requires only a small brush and does not need to be replaced, as shown in FIG. As described above, "a rotating plate having a plurality of arms protruding in the opposite direction of the rotating shaft at equal intervals in the radial direction is provided at the tip of the rotating shaft connected to the hand-held rotary driving device, Each of the plurality of arms has a configuration in which brushes are detachably provided, and the plurality of brushes are rotated around an extension line in the opposite direction of the rotation shaft by rotating the rotation shaft. '' Is.

  However, the “rotating wire brush” disclosed in Patent Document 1 is provided with “a rotating plate having a plurality of arms protruding in the opposite direction of the rotating shaft at equal intervals in the radial direction, and a brush can be attached to and detached from each of the plurality of arms. It is considered that a simple structure for carrying out kelen is inevitably heavy and difficult to carry out kelen work at high places.

  In addition, it is considered that the “rotating wire brush” of this Patent Document 1 is “consumable that is economical because the main body does not need to be replaced with only a small brush”, but is small as a consumable. It can be considered that the work of replacing the brush is very troublesome because there are a plurality of places to be replaced. In addition, when using the “rotating wire brush” of this Patent Document 1, as shown in FIG. 7, an open part is formed between the rotating plate and the kelen object, and the dropping part is dropped from the open part. It is also conceivable that the rust and old paint that has been scattered will scatter to the outside, deteriorating the working environment.

  Therefore, the present inventors have completed the present invention as a result of various investigations on how to make it possible to perform the cleansing work without incurring costs without deteriorating the work environment. is there.

  That is, an object of the present invention is to provide a kelen device that does not deteriorate the working environment, can be easily carried out even at a high place without incurring costs.

In order to solve the above problems, first, the means taken by the invention according to claim 1 will be described with reference numerals used in the description of the embodiments described later.
"A kelen 10 that is rotationally driven by connecting the rotating shaft 11 to the rotating device 20,
A bottomed rotating body 12 connected to the rotating shaft 11, a dust collecting chamber 13 formed on the rotating shaft 11 side in the rotating body 12, and between the dust collecting chamber 13 and the opening 12 a of the rotating body 12. A kelen device 10, which is provided with a kelen part 14 having a kelen object insertion passage 15 provided in the dust collection chamber 13.
It is.

  This keren device 10 performs “Kellen work”, and as shown in FIG. 1, a rotating shaft 11 integrated with the rotating body 12 is connected to a rotating device 20 outside the present invention, and this rotating device. It is rotated by 20 rotational driving forces. On the other hand, the keren device 10 is operated by an operator so that the to-be-cleaned object 30 such as a bolt and a nut to be cleansed is inserted into the to-be-cleaned object insertion passage 15 of the kelen part 14 encased by the rotary body 12. It is operated by adjusting the direction of the rotating device 20. If the keren device 10 is rotated by the rotating device 20, the kelen object 30 contained in the kelen object insertion passage 15 is swollen by the surrounding kelen part 14.

  During such a cleansing operation by the cleansing part 14, dust 40 such as rust and dust dropped from the cleansing object 30 is captured by the cleansing part 14 itself or from the cleansing object insertion passage 15 to the dust collecting chamber 13. It is sent into the inside and is not scattered around the outer periphery of the keren device 10. This is because during the cleansing work, the to-be-cleaned object 30 that is the source of the dust 40 is encased by the cleansing portion 14, and the cleansing portion 14 itself touches the outside air only through the opening 12 a of the rotating body 12. This is because the kelen object insertion passage 15 is closed by the insertion of the kelen object 30 and communicates only with the dust collection chamber 13 in the rotary body 12.

  In addition, when the cleansing operation is performed by the cleansing device 10, the cleansing portion 14 is naturally consumed and partially fined. However, the finely powdered cleansing portion 14 also becomes dust 40, and It is captured by the portion 14 itself or sent into the dust collecting chamber 13 from the kelen object insertion passage 15. That is, the finely divided kelen portion 14 is not scattered outside as well as the trash 40 such as rust and dust.

  Further, the rotating body 12 is configured to transmit the rotational force from the rotating shaft 11 to the keren part 14 and enclose the kaleen part 14 while holding it inside to secure the dust collecting chamber 13 which is a simple space. Therefore, it is necessary to make the bottom plate 12b with the bottom plate 12b. However, the bottom plate 12b has a very simple structure so that the weight can be easily reduced, and an inexpensive material can be applied. That is, since the keren device 10 is also reduced in weight, the keren work at a high place can be easily performed.

  In addition, the rotating body 12 may be disposed of as a consumable item when the internal kelen portion 14 is completely consumed, and plays a role in reducing the overall cost of the keren device 10. It is what. In other words, the keren device 10 according to the first aspect of the present invention is assumed to be consumed when the kelen part 14 is completely consumed, and not only the replacement work of the kelen part 14 is unnecessary, but also the overall cost reduction. This is what was planned.

  Therefore, the keren device 10 according to the first aspect of the present invention does not deteriorate the working environment, and can easily perform keren work even at a high place without incurring costs.

Moreover, in order to solve the said subject, the means which the invention which concerns on Claim 2 took about the keren device 10 of the said Claim 1,
“In the rotating body 12, the dust collection chamber 13 and the kelen portion 14 are partitioned, and a support plate 16 that prevents the kelen portion 14 from being fitted into the dust collection chamber 13 is attached.”
It is.

  As shown in FIG. 3 or FIG. 6, the kelen device 10 according to claim 2 has a support plate 16 attached to the rotary body 12, and the support plate 16 allows the dust collection chamber 13 and the kelen portion 14 to be attached. And the fitting of the keren part 14 to the dust collecting chamber 13 side is prevented.

  Since the keren device 10 has the support plate 16 attached in the rotary body 12, the kelen part 14 is loosely fixed to the rotary body 12, and the kelen part 14 falls into the dust collecting chamber 13 during the kelen operation. Even if it tries to insert, since this support plate 16 prevents it, it does not eat a "ska" during a keren operation. In addition, since the to-be-processed object insertion path 15 of the keren part 14 and the dust collecting chamber 13 in the rotary body 12 must be connected, it goes without saying that the support plate 16 has a communication hole 16a.

  Further, if only the kelen portion 14 is a consumable item, the support plate 16 serves as a positioning member when the new kelen portion 14 is housed and fixed in the rotating body 12.

  Therefore, the keren device 10 according to the second aspect exhibits the same function as that of the first aspect, and does not eat “ska” during the keren operation.

Furthermore, in order to solve the above-mentioned problem, the means taken by the invention according to claim 3 is the keren brush 10 according to claim 1 or 2,
“The kelen portion 14 is fixed to the inside of the rotary body 12 and the tip thereof is formed by a large number of wires 14 a that form the kelen object insertion passage 15.
It is.

  As shown in FIGS. 2 to 4, the kelen device 10 according to the third aspect is such that the kelen portion 14 is formed by a large number of wires 14 a, and the kelen of the object 30 can be made by the tips of the wires 14 a. It is what I did. Therefore, in this keren device 10, as shown in FIG. 3, for example, the kelen object insertion passage 15 is formed by the tip of each wire 14a. For this reason, the tip of each wire rod 14a abuts against all the part of the kelen object 30 inserted into the kelen object insertion passage 15 to rust and remove old paint in that part, and also enters a small gap. Therefore, it is also possible to scrape the dust of that part.

  As the wire 14a, a synthetic resin wire or a metal wire having such a strength that the kelen material 30 can be removed is employed. Of course, the wire diameters of these synthetic resin wires and metal wires are appropriately set in accordance with the material so as to ensure the strength that enables the kelen material 30 to be washed.

  As shown in FIG. 3, the length of each wire 14 a is adjusted so that the tip (inner end) forms a kelen article insertion passage 15. The kelen article insertion passage 15 is shown in FIG. 3. It is not necessary to adjust so that it becomes clear. For example, the adjustment may be made to the extent that the to-be-quenched object insertion passage 15 is formed when the to-be-cured objects 30 are pushed into each other so that the ends intersect each other. In addition, each wire 14a is fixed to the inner surface side of the rotary body 12 at its end (outer end). As a fixing method, the wire 14a is implanted in the rotary body 12 like a toothbrush. Or the end portion is bonded to the inner surface of the rotary body 12, and further, as in an embodiment described later, the wire 14 a is flocked or bonded to the support frame 14 c and the support frame 14 c is fixed to the rotary body 12. There are various methods.

  As a result of the above, the tip of the wire 14a forms a kelen object insertion passage 15 into which the kelen object 30 to be keelted is inserted. The kelen object 30 that has been inserted into the keren object insertion passage 15 is keren. Of course, except for the tip of each wire 14a, the insertion of the kelen object 30 into the keren device 10 is prevented. Therefore, when the kelen portion 14 is formed by a large number of wires 14a, the rotating body 12 is used. Even when the opening 12a is used in a downward state as shown in FIG. 1, it is possible to insert the kelen object 30 into the kelen object insertion passage 15 without visually confirming it. It is.

  Each wire 14a is pulverized or broken by continuing the keren operation. The finely pulverized wire 14a enters between the other wires 14a or passes through the kelen object insertion passage 15. It is sent into the dust collection chamber 13 and is not scattered outside. On the contrary, the finely divided wire 14a which has entered between the other wire rods 14a or sent into the dust collecting chamber 13 through the kelen object insertion passage 15 is rotated after the kelen work is finished. If the opening 12a of the body 12 is directed toward the vessel and the entire keren device 10 is shaken or stimulated, it can be discarded as garbage 40 in the vessel. For this reason, also in this keren device 10, work environment is not polluted by the keren work.

  Therefore, the keren device 10 according to the third aspect exhibits functions similar to those of the first aspect or the second aspect, and the kelen can be more reliably performed by the tip of the wire 14a.

Further, the means taken by the invention according to claim 4 is the keren brush 10 according to claim 3,
“The wire 14a is a wire”
It is that.

  By using the wire 14a made of a wire in the kelen portion 14 constituting the keren device 10, the wire itself can sufficiently exhibit the property of “thin but strong”. The work can be done more efficiently.

  Further, by adopting the wire rod 14a made of a wire, the durability of the kelen portion 14 becomes excellent, and the durability of the entire kelen device 10 is enhanced. Of course, since each wire 14a itself can be made thin, not only can the rust and old paint on the surface of the kelen object 30 be effectively removed, but also dust that has entered into the small gaps in the kelen object 30 can be reliably ensured. It can be scraped out, and the surface finish of the kelen object 30 can be made very beautiful.

  Therefore, the keren device 10 according to the fourth aspect of the invention exhibits the same function as that of the third aspect of the invention, and can perform the surface finishing of the kelen object 30 very beautifully.

And in order to solve the said subject, the means which the invention which concerns on Claim 5 took about the brush 10 for keren of the said Claim 1 or Claim 2,
“The kelen portion 14 is housed and fixed in the rotary body 12 and is a lump cleaning material 14b having a kelen article insertion passage 15 in the center.”
It is.

  As the lump cleaning material 14b, as shown in FIGS. 5 and 6, a thin and long metal material such as a material constituting a “metal scrubber” is lump-shaped, and a relatively hard synthetic resin material is used as a sponge. In addition, there are those formed into a shape, and further, abrasive powder mixed in this sponge-like material. These bulk cleaning materials 14b can be easily fixed to the inner surface of the rotary body 12 by applying an adhesive to the surface and pushing it into the rotary body 12 as it is. .

  The lump cleaning material 14b thus formed can be crushed when pressed, and can be restored to its original state when the pressing force is lost. In addition to being able to be inserted into the surface of the object 30, the surface of the object 30 can be in contact with the surface of the object 30. Of course, the dust 40 generated by the cleansing by the lump cleaning material 14b is not captured by the lump cleaning material 14b itself or sent into the dust collecting chamber 13 and scattered outside.

  Further, as described above, since the lump cleaning material 14b can be easily attached to the rotary body 12, it facilitates the manufacture of the keren device 10 and has some elasticity, so it is somewhat crushed. By fixing the rotating body 12 in the state, the durability of the kelen portion 14 made of the lump cleaning material 14b can be enhanced. As a result, the cost of the entire keren device 10 can be reduced.

  Therefore, the keren device 10 according to the fifth aspect exhibits the same function as that of the first or second aspect, and has high durability and cost reduction.

As described above, the present invention
"A kelen 10 that is rotationally driven by connecting the rotating shaft 11 to the rotating device 20,
A bottomed rotating body 12 connected to the rotating shaft 11, a dust collecting chamber 13 formed on the rotating shaft 11 side in the rotating body 12, and between the dust collecting chamber 13 and the opening 12 a of the rotating body 12. And a kelen portion 14 having a kelen object insertion passage 15 that passes through the dust collection chamber 13.
Therefore, it is possible to provide a kelen device 10 that can easily perform keren work even at a high place without incurring costs and without deteriorating the work environment.

It is a perspective view which shows a mode that the keren object 30 exposed on the folded-plate roof is performed using the keren device 10 which concerns on this invention. It is the expansion perspective view which looked at the keren device 10 from the bottom. It is a longitudinal cross-sectional view of the keren device 10. It is a bottom view of the keren device 10. It is a perspective view at the time of comprising the kelen part 14 of the keren device 10 with the lump cleaning material 14b. It is a longitudinal cross-sectional view of the keren device 10. It is a longitudinal cross-sectional view of the rotating wire brush shown by patent document 1. FIG.

  Next, the invention according to each claim configured as described above will be described with respect to the keren device 10 which is the embodiment shown in the drawings. In FIG. A state of performing the cleansing of the to-be-squeezed object 30 exposed above is shown.

  As shown in FIGS. 2 to 6, the keren device 10 includes a bottomed rotary body 12 connected to the rotary shaft 11, and a dust collection chamber 13 formed on the rotary shaft 11 side in the rotary body 12. And a kelen portion 14 provided between the dust collecting chamber 13 and the opening 12 a of the rotary body 12 and having a kelen object insertion passage 15 passing through the dust collecting chamber 13. In this case, FIGS. 2 to 4 exemplify those made of the wire 14a as the keren portion 14, and FIGS. 5 and 6 exemplify those made of the block cleaning material 14b as the kelen portion 14.

  The rotating shaft 11 of the keren device 10 is attached to the center of a bottom plate 12b that closes one opening of a cylindrical rotating body 12, and is connected to a general rotating device 20 to connect the rotating device 20 to the rotating device 20. Is transmitted to the rotary body 12. In other words, the keren device 10 connected to the rotating device 20 via the rotating shaft 11 is rotationally driven around the axis of the rotating body 12 by the rotational driving of the rotating device 20.

  The rotary body 12 has a cylindrical shape as described above, and has a shape that does not cause anxiety to the worker so that it remains cylindrical even during the cleansing operation, that is, during rotation. . Further, the rotary body 12 has a support plate 16 in the middle thereof, and the bottom plate 12b side portion of the support plate 16 serves as a dust collection chamber 13, and the support plate 16 and the opening 12a of the rotary body 12 are connected to each other. It is a part which accommodates the keren part 14 in between. The support plate 16 is formed with a communication hole 16a for allowing the dust collection chamber 13 and the kelen object insertion passage 15 of the kelen portion 14 to communicate with each other.

  Further, the rotary body 12 secures the dust collection chamber 13 and the portion for storing the kelen portion 14 inside, and can transmit the rotational driving force from the rotary shaft 11 to the kelen portion 14. As long as these conditions are satisfied, the material may be made of any material as well as metal. In this sense, the rotary body 12 may be integrally molded using, for example, a synthetic resin as a material. In this case, the bottom plate 12b and the rotary shaft 11 can also be integrally molded.

  The dust collection chamber 13 defined in the rotary body 12 is a portion that collects the dust 40 removed by the kelen portion 14 so that the dust 40 does not scatter outside the keren device 10. The keren device 10 according to the present embodiment is a so-called “disposable” device that discards the entire garbage including the dust 40 in the dust collecting chamber 13 when the kelen unit 14 is consumed to some extent. Assuming that the inside of the dust collection chamber 13 is filled with the dust 40 before it is consumed, the “rotation waste” may be provided in the rotary body 12 around the dust collection chamber 13.

  The keren part 14 is formed of a wire made of a natural material such as palm or coconut shell, a synthetic resin wire, or a wire 14a made of a metal wire such as a wire (as shown in FIGS. 2 to 4), and a natural material. In some cases, the bulk cleaning material 14b is made of synthetic resin or metal (FIGS. 5 and 6).

  When a large number of wires 14a are employed as the kelen portion 14, as shown in FIGS. 2 to 4, each wire 14a is fixed to the inner side of the rotary body 12, and each tip is inserted into the kelen object. A passage 15 is formed. As shown in FIGS. 5 and 6, such a kelen object insertion passage 15 is formed at the center of the lump cleaning material 14 b even when the kelen portion 14 is formed by the lump cleaning material 14 b. .

  Moreover, when many wire rods 14a are employ | adopted as the keren part 14, in order to prevent these wire rods 14a from separating, the support frame 14c is used as shown in FIGS. The outer end of each wire 14a is attached to the support frame 14c by means such as adhesion, insertion, or incorporation. At that time, the length of each wire 14a is made the same and a flat support frame is provided. When the support frame 14c is wound while the wire rod 14a is placed inside, the above-described kelen object insertion passage 15 is naturally formed at the center of the kelen portion 14.

  By the way, if the support frame 14c itself is provided with a forming margin for the attachment portion of the wire 14a and the dust collection chamber 13, and the support frame 14c is rounded after the attachment of each wire 14a, the support frame 14c is supported. The frame 14c can be used in place of the rotary body 12. Of course, in that case, the support frame 14c may also have a portion that becomes the rotary shaft 11 and the bottom plate 12b described above when the support frame 14c is rolled.

  On the other hand, in the keren device 10 of the embodiment shown in FIGS. 5 and 6, a thin and long metal material such as a material constituting a “metal scrubber” is used as the bulk cleaning material 14 b adopted as the kelen portion 14. There are a lump, a sponge made of a relatively hard synthetic resin material, and a sponge powder mixed with abrasive powder. These bulk cleaning materials 14b can be easily fixed to the inner surface of the rotary body 12 by applying an adhesive to the surface and pushing it into the rotary body 12 as it is. For this reason, the support frame 14c in the case where the wire 14a is employed as the keren portion 14 is almost unnecessary.

  The lump cleaning material 14b formed of the material as described above has elasticity to be crushed if it is pushed and restored to its original state if the pushing force is lost, and thus the kelen object insertion passage 15 formed thereby is also free. Can be changed. Therefore, as shown in FIGS. 5 and 6, even if the kelen object insertion passage 15 is not actually opened, the kelen object 30 can be freely inserted into the kelen object insertion path 15. In addition, since the lump cleaning material 14b sufficiently abuts on the surface of the object 30 with elasticity, the lump by the lump cleaning material 14b is sufficiently performed.

  Moreover, since such a lump cleaning material 14b has elasticity, it can be easily attached to the rotary body 12 and fixed in the rotary body 12 in a slightly crushed state. It can be expanded by the amount consumed. Thereby, the fixing operation | work to the rotary body 12 of the said block cleaning material 14b can be made easy, durability of the keren part 14 which consists of the block cleaning material 14b can be improved, and the cost of the said kelen apparatus 10 whole can be reduced. Become.
