この考案は建設機械の作業機に設けられた作業機シリン
ダの保護カバ装置に関する。[Detailed Description of the Invention] This invention relates to a protective cover device for a working machine cylinder provided in a working machine of a construction machine.
従来建設機械の作業機にはこれを駆動するための作業機
シリンダが設けられている。Conventionally, a working machine of a construction machine is provided with a working machine cylinder for driving the working machine.
これら作業機シリンダのうちブレードチルトシリンダの
ように比較的地上に近い位置に設置されるシリンダにつ
いては土砂などによりピストンロッドやシール部分が損
傷なれないようロッド部分に布製の蛇腹状ブーツなどを
取付けていた。Among these work equipment cylinders, cylinders that are installed relatively close to the ground, such as blade tilt cylinders, are fitted with cloth bellows-like boots on the rods to prevent the piston rods and seals from being damaged by dirt, etc. Ta.
しかしこの蛇腹状ブーツは耐久性に乏しいことから早期
に損傷し、破損したブーツによりロッドが損傷するなど
の欠点があった。However, this bellows-like boot has shortcomings such as poor durability and early damage, and the rod being damaged by the broken boot.
この考案はかかる従来の欠点を除去する目的でなされた
もので、長期間使用していても破損の虞れのない作業機
シリンダの保護カバ装置を簡単な構成で提供しようとす
るものである。This invention was made with the aim of eliminating such conventional drawbacks, and is intended to provide a protective cover device for a working machine cylinder with a simple structure that is free from damage even after long-term use.
以下この考案を図面の一実施例について詳述する。This invention will be described in detail below with reference to one embodiment of the drawings.
図において１は図示しない建設機械の作業機に使用され
た作業機シリンダで、一端側よりロッド２が突設されて
いると共に、外周部には断面がほぼコ字形をなすブラケ
ット３が開口部をシリンダ外周側へ向け、かつ軸線方向
に沿って取付けられている。In the figure, reference numeral 1 denotes a work machine cylinder used for a work machine of a construction machine (not shown).A rod 2 is provided protruding from one end side, and a bracket 3 having a substantially U-shaped cross section has an opening on the outer periphery. It is attached toward the outer circumferential side of the cylinder and along the axial direction.
そしてこのブラケット３内に上記作業機シリンダ１へ配
管された高圧ホースなどの管路１２が挿通されていると
共に、上記ブラケット３上には幅の狭い板材４ａと、こ
れより幅の広い板材４ｂが重ねた状態で固着具５により
固着され、これら板材４ａ 、４ｂによりガイドレール
４が構成されている。A conduit 12 such as a high-pressure hose connected to the work machine cylinder 1 is inserted into this bracket 3, and a narrow plate 4a and a wider plate 4b are placed on the bracket 3. The plates 4a and 4b are fixed to each other by a fixing member 5 in a stacked state, and a guide rail 4 is constituted by these plate members 4a and 4b.
上記ガイドレール４の各凹溝４Ｃ内にはカバ６の内側に
固着したガイド部材７の先端部が嵌入されて、カバ６の
移動を案内すると共に、カバ６の内側には上記ガイドレ
ール４の上側の板材４ｂ上面と摺接して、カバ６の上下
方向のガタッキを吸収する摺動部材８がガイドレール４
に沿って固着されている。The tip of a guide member 7 fixed to the inside of the cover 6 is fitted into each groove 4C of the guide rail 4 to guide the movement of the cover 6. The guide rail 4 includes a sliding member 8 that slides on the upper surface of the upper plate 4b and absorbs the vertical wobbling of the cover 6.
It is fixed along the
またカバ６のロッド２側端は固着具９により取付は部材
１０の一端側に固着されていると共に、取付は部材１０
の他端側はロッド２の先端側に固着されている。The end of the cover 6 on the rod 2 side is fixed to one end of the member 10 by a fixing tool 9, and the cover 6 is fixed to one end of the member 10.
The other end is fixed to the tip of the rod 2.
この考案は以上詳述したようになるから、作業中に岩石
などが作業機シリンダ１上に落下しても、作業機シリン
ダ１に配管された高圧ホースなどの管路１２はブラケッ
ト３により保護されることから、岩石などにより管路１
２が破断されたり、シリンダ１自体が損傷されることが
ないと共に、作業機シリンダ１よりロッド２が突出する
と、これと一体にカバ６が引き出され、ロッド２の外周
部を覆うため、土砂などがロッド２付近に落下しても、
カバ６により保護されて、ロッド２やシールなどが土砂
により損傷されるのを防止できる。Since this device is as described in detail above, even if a rock or the like falls onto the cylinder 1 of the work machine during work, the conduit 12 such as a high-pressure hose connected to the cylinder 1 of the work machine is protected by the bracket 3. Therefore, due to rocks etc., pipe 1
2 will not be broken or the cylinder 1 itself will be damaged, and when the rod 2 protrudes from the work equipment cylinder 1, the cover 6 is pulled out together with the rod 2 to cover the outer circumference of the rod 2, so that dirt, sand, etc. Even if it falls near rod 2,
Protected by the cover 6, the rod 2, seal, etc. can be prevented from being damaged by earth and sand.
また、ブーツなどと異なり長期間使用していても破損す
ることがないので、屡々交換する必要がなく経済的であ
ると共に、カバ６の後端が作業シリンダ１に沿って布設
されたガイドレール４に案内されるため、ロッド２の伸
縮に伴いカバ６も円滑に移動し、ロッド２に不用な外力
が加わることもない。In addition, unlike boots, etc., it does not get damaged even after long-term use, so it does not need to be replaced frequently, making it economical. Since the cover 6 is guided by the rod 2, the cover 6 moves smoothly as the rod 2 expands and contracts, and no unnecessary external force is applied to the rod 2.
なお上記実施例ではカバ６を断面逆り字形とじたがロッ
ド２を覆えれば勿論他の形状としてもよい。In the above embodiment, the cover 6 has an inverted cross section, but it may of course have other shapes as long as it can cover the rod 2.
