大きな防食金属の溶着した帯板を氷室内に簡単に装着で
きるようにした防食金属取付装置に関する。
[Detailed Description of the Invention] The present invention relates to an anti-corrosion metal mounting device which allows a welded band plate of anti-corrosion metal as large as possible to be easily installed in an ice chamber through a small window hole formed in a cylinder side wall.

Zinc has traditionally been used as a corrosion-resistant metal.
For cylinder liners, a thin annular groove with a rectangular cross section is provided on the outer surface of the cylinder liner facing the ice compartment, and anticorrosive zinc is tightly fitted into the annular groove.

態に近くなり、防食亜鉛の働きが著しく減少する。
However, in this case, as corrosion of the anti-corrosive zinc progresses, cooling water enters between the liner and the anti-corrosive zinc, and the two metals become close to insulating, resulting in a significant reduction in the effectiveness of the anti-corrosive zinc.

シリンダ用としては氷室に面したシリンダ側壁に窓孔を

For cylinders, a window hole is made in the side wall of the cylinder facing the ice chamber, and a lid with anti-corrosion zinc fixed to the inner surface is fixed to the window hole, so that the anti-corrosion metal protrudes into the ice chamber from the window hole.

ところがその場合はライナの裏側部分までは充分電位挙
を保てず、防食効果が低い欠点があった。
However, in this case, the potential could not be maintained sufficiently to the back side of the liner, and the anticorrosion effect was low.

(2) When the anti-corrosion metal 13 is attached to the lid 5, the band plate 11
Since the anti-corrosion metals 13 on top of 12 are alternately overlapped,
Insertion through the small window hole 4 is easy, and a strip plate with anti-corrosion metal that is as large as possible for the size of the window hole 4 can be pushed in with ease. Therefore, a decrease in the strength of the cylinder 1 can be prevented. Since the lid 5 is made smaller, the cost is also reduced.

When embodying the present invention, it is advantageous to use an aluminum-based aranode as the anti-corrosion metal, since the anti-corrosion metal is mounted in a cantilevered manner, which reduces the load on the supporting portion of the strip.

帯板11.12の回り止めのためには、図示のピン16
の代りにボルトを使用することもできる。
To prevent the strips 11.12 from rotating, the illustrated pin 16 is used.
You can also use bolts instead.

又ブラケット8の垂直面に帯板11.12の巾と等しい
巾の浅い溝を設け、そこに帯板11.12を噛合わせて
水平姿勢を保持させることもできる。
It is also possible to provide a shallow groove on the vertical surface of the bracket 8 with a width equal to the width of the strips 11, 12, and to engage the strips 11, 12 therein to maintain the horizontal position.

帯板11.12の端部はブラケット8の一側面にまとめ
