Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a rotating wire brush that removes rust and cleans the surfaces of bolts and nuts fastened to a part of a structure such as a bridge.

[0002]

[Prior art]

 Since structures such as bridges get dirty due to rust, etc., it is necessary to paint them regularly. In addition, it is necessary to paint even when newly constructed. When painting, it is necessary to clean and remove old paint films and rust, but for parts that use many bolts and nuts, such as splice joints, clean many bolts and nuts that have been fastened. Must-have.

Not only the splice joint but also a portion where a large number of bolts and nuts are used must be cleaned at a time. The bolts and nuts are not continuous like a flat surface like a flat plate, but are three-dimensional and have various surfaces, which makes it difficult to clean.

Conventionally, when cleaning the surfaces of the bolts and nuts of the above structure, a hand-held rotating brush device 15 with a motor shown in FIG. Then, the brush 14 with the cup at the tip was rotated and the tip surface 16 of the brush was pressed against various surfaces of the bolt and nut to clean those surfaces.

When the brush 14 with a cup is applied to various surfaces of bolts and nuts, the handheld rotary brush device 15 is tilted or moved, and the brush surface is moved to perform cleaning.

[0006]

[Problems to be solved by the device]

 Therefore, it takes a long time to clean, the worker is easily tired, and due to lack of skill of the worker, the uncleaned residue occurs, and it is difficult to completely clean the worker. In addition, since the brush with a cup rotates at high speed, if it hits a protrusion such as a corner of a nut, the brush with a cup jumps and it is dangerous, and the brush with a cup is worn out.

The present invention has been conceived in order to eliminate the above-mentioned drawbacks, and it is possible to clean a desired portion cleanly by holding the hand without moving it, and it is possible to clean a plurality of surfaces at a time. Therefore, the cleaning time can be shortened, the fatigue of the worker can be greatly reduced, and the object is to provide an economical rotating wire brush in which the consumable parts are only small brushes and the main body does not need to be replaced.

[0008]

[Means for Solving the Problems]

 In this invention, a rotary plate having a plurality of arms protruding in the opposite direction of the rotary shaft at equal intervals in a radial direction is provided at the tip of a rotary shaft connected to a handheld rotary engine, and the rotary plate is provided in the rotary plate. , A brush is detachably attached to each of the plurality of arms, and by rotating the rotating shaft, the plurality of brushes rotate around an extension line in the opposite direction of the rotating shaft. The summary will be given.

[0009]

[Action]

 Apply the rotating wire brush configured as described above to the dirty bolts and nuts that are fastened so that it surrounds the brush with multiple brushes, and rotate the rotating shaft to surround it. The tip of the brush hits the desired part of the bolt / nut while rotating normally, and it works to clean the desired part simply by holding it by hand.

When it is desired to clean a plurality of desired surfaces at one time, a plurality of surfaces can be cleaned at a time by combining the arm to be attached and the brush having different positions and angles and working as described above.

By using a rotating wire brush having some combinations of arms and brushes, cleaning can be performed easily in a short time.

【Example】

 Examples will be described with reference to the drawings. FIG. 1 is a plan view showing a first embodiment of a rotating wire brush according to the present invention. A rotating plate 2 is screwed onto a rotating shaft 1, and the rotating plate 2 is centered on the position of the rotating shaft 1. As shown, the vertical arms 3 and the inclined arms 4 are alternately provided at equal intervals of 60 degrees radially. Brush portions 5 with protruding bolts are attached to each arm by nuts 6 via washers one by one.

FIG. 2 is a cross-sectional view taken along the line AA of the rotating wire brush of the first embodiment, in which the vertical arm 3 and the tilted arm 4 extend downward, and one brush portion 5 is provided at the tip of the washer 7. It is shown to be fastened at nut 6 via. The brush part is removable. According to this embodiment, the periphery of the two parts of the bolt / nut 11 to be cleaned can be cleaned at one time.

FIGS. 3 and 4 are a side view and a front view of the brush part 5. In order to fix the brush part 5 to the arm and prevent the brush part from coming off, a protruding member 8 for sandwiching both sides of the arm is provided. In addition, the bristle wire 9 of the brush is held by the brush portion 5 near the root.

The brush portion 5 is not limited to the shape and the angle shown in FIGS. 1 to 4, and the brush portion 5 shown in the side view and the front view in FIGS. There are types such as the brush portion 5 shown in the side view and the front view in FIG. 12, and they are prepared for replacement. Therefore, various parts of the bolt / nut 11 to be cleaned can be cleaned.

FIG. 5 is a plan view showing a second embodiment, in which a rotary plate 2 having a shape of a regular hexagon is screwed onto a rotary shaft 1 and a vertical arm 3 and a brush portion 5 are integrated into a vertical structure with a brush. The arms 12 are detachably attached to the six sides of the rotating plate 2 with bolts 13. Two types of vertical arms with brushes 12 having different shapes are alternately attached.

FIG. 6 is a cross-sectional view taken along the line BB of the second embodiment, and it is shown that two types of vertical arm with a brush 12 having different shapes are attached. One type is to make the brush oblique and clean the flat plate around the bolts and nuts 11 to be cleaned extensively. Another type is to set the brush upright and clean the hex face of the nut.

FIGS. 7 and 8 show a cross section of a rotating brush to which different examples of the vertical arm 12 with a brush of the second embodiment are attached.・ Vertical arm with brush 12 designed to clean the screw part of the bolt of nut 11, and vertical arm with brush 12 designed to clean the washer part by tilting the brush sideways down a little. Can be seen. In FIG. 8 one can see the vertical arm with a brush 12 with the brush lying down and tilted slightly downward to clean the top of the nut.

The rotating wire brush shown in FIG. 8 has three brushed vertical arms 12 attached as a whole.

Although the number of arms and the number of brushes are plural, any number may be attached as long as it can stably rotate as a rotating brush, and there is no particular limitation.

In the first embodiment, as in the second embodiment, various brush angles and positions can be used.

In both the first and second embodiments, the rotating shaft 1 and the rotating plate 2 are described to be screwed together, but the purpose is to firmly connect them, and in addition, joining by welding or caulking is also considered. Be released.

Since a plurality of brushes are used and the brushes rotate in close contact with the cleaning surface, it is possible to reduce the wear of the brushes.

Since the bolts and nuts to be cleaned are covered from above and the cleaning is performed while stably rotating around the rotating shaft and the device is held, the risk of the brush jumping can be prevented. it can.

In the second embodiment, when the brush is consumed, only the portion of the bristle wire may be replaced. In the first embodiment, the brush part 5 may be replaced.

[0026]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects.

Since the arm and the brush are arranged so as to surround the extension line in the opposite direction of the rotation shaft and rotate stably around the rotation shaft, it is possible to cover the bolts and nuts to be cleaned from above. You can clean without holding your hands just by holding.

Since a plurality of types of brushes are attached in advance assuming the surfaces of the bolts and nuts to be cleaned, desired parts can be easily cleaned, and cleaning of a plurality of surfaces at once is possible. With a combination of several different rotating wire brushes, you can achieve near-perfect cleaning.

Therefore, the cleaning time can be shortened and the fatigue of the worker can be significantly reduced.

Since the brush is removable, only the brush needs to be replaced when it is worn out, and the main body need not be replaced, which is economical.
