Description

【０００１】
【発明の属する技術分野】
本発明は、建設機械のフレームに防振部材を介してキャビンを取付ける取付構造に関し、特に防振部材の交換を容易に行えるよう考慮したものである。
【０００２】
【従来の技術】
図５は従来のキャビン取付構造を示している。
作業時や走行時の振動がキャビン１０へ伝達されるのを抑制するために、キャビン１０は複数の防振ゴム２０を介して建設機械のフレーム３０に取付けられる。図６，図７に示すように、防振ゴム２０はフレーム３０にボルト４１およびナット部３０ａにより螺着されるフランジ２１と、キャビン１０のフロアプレート１１を下方から貫通するねじ部２２ａが突設されたキャビン側取付部２２とを有し、キャビン取付部２２は、キャビン１０内部からねじ部２２ａにナット４２を螺合することによりフロアプレート１１に固着される。なお、図５では防振ゴム２０を１箇所のみ示したが、実際は６箇所に設けられる。
【０００３】
長時間の使用によって防振ゴム２０にへたりが生じた場合、これを新品と交換する必要がある。上述した従来の取付構造においては、防振ゴム２０の交換にあたってまず全ての防振ゴム２０に対してナット４２をねじ部２２ａから外し、防振ゴム２０とキャビン１０との連結を解除した状態でクレーンを用いてキャビン１０を吊り上げ、次いでボルト４１を外して各防振ゴム２０とフレーム３０との連結を解除し、防振ゴム２０を一つずつフロアプレート１１とフレーム３０との隙間に引き上げて取り出す。しかる後、上述とは逆の手順で新品の防振ゴム２０を取付ける。
【０００４】
【発明が解決しようとする課題】
このように従来の構成では、防振ゴム２０の交換にクレーンが必要となり手間と費用がかかる。特にクレーンでキャビン１０を吊り上げる方式では、へたりの激しい防振ゴム２０のみを交換したい場合でも全ての防振ゴム２０とフロアプレート１１との連結を解除する必要があり、作業効率がきわめて悪い。
【０００５】
本発明の目的は、クレーン等の補助機械を用いることなく防振部材の交換が可能な建設機械のキャビン取付構造を提供することにある。
【０００６】
【課題を解決するための手段】
本発明は、建設機械を構成するフレームの上部に防振部材を介してキャビンを取付ける取付構造に適用される。
そして、請求項１の発明では、防振部材は、フレームの下方からフレームに着脱可能に連結されるフレーム側連結部と、キャビンのフロアプレートにキャビン内部から着脱可能に連結されるキャビン側連結部とを有し、キャビン側連結部とフロアプレートとの連結、およびフレーム側連結部とフレームとの連結を共に解除した状態で防振部材をフレーム側連結部とキャビン側連結部とが一体化された状態でフレームの下方に取り出し可能に構成する。
【０００７】
請求項２の発明では、キャビンのフロアプレートに形成された孔部を覆うようにフロアプレートにキャビン内部から着脱可能に連結される取付部材を備え、防振部材は、フレームに着脱可能に連結されるフレーム側連結部と、取付部材にキャビン内部から着脱可能に連結されるキャビン側連結部とを有し、取付部材とフロアプレートとの連結、およびフレーム側連結部とフレームとの連結を共に解除した状態で防振部材を上記孔部からキャビン内部に取り出し可能に構成する。
【０００８】
【発明の実施の形態】
−第１の実施の形態−
図１および図２により本発明の第１の実施の形態を説明する。なお、図５〜図７と同様の構成要素には同一の符号を付す。
フレーム３０には防振ゴム２０が貫通する孔３０Ｈが形成され、キャビン１０のフロアプレート１１には防振ゴム２０のねじ部２２ａが貫通するねじ貫通孔１１Ｈが形成されている。防振ゴム２０のフランジ２１には一対の取付部材５１がボルト４１およびナット５１Ｎにより螺着され、各取付部材５１はボルト４３およびナット３０Ｎによりフレーム３０の下方からフレーム３０に螺着される。またフロアプレート１１の孔１１Ｈを貫通するねじ部２２ａにナット４１を螺合することにより防振ゴム２０がフロアプレート１１に締結される。なお、この取付構造は、上述したように単一のキャビン１０に対して複数箇所（例えば６箇所）に設けられる。
【０００９】
防振ゴム２０の交換手順を説明する。
交換が必要となった防振ゴム２０に対し、まずキャビン１０内部からナット４２を外すことにより防振ゴム２０とフロアプレート１１との連結を解除する。次いでフレーム３０の下方からボルト４３を外し、防振ゴム２０とフレーム３０との連結を解除する。これにより取付部材５１が取り付いたままの防振ゴム２０をフレーム３０の下方に取り出すことができる。このとき、他の防振ゴム２０は装着されたままなので、キャビン１０が不所望に下降することはない。次に、新品の防振ゴム２０に取付部材５１をボルト４１およびナット部５１Ｎにより取付け、防振ゴム２０をフレーム３０の下方から孔３０Ｈに通す。キャビン側連結部２２のねじ部２２ａがフロアプレート１１の孔１１Ｈを貫通する状態で取付部材５１をボルト４３およびナット部３０Ｎによりフレーム３０に螺着する。ナット部３０Ｎは予めフレーム３０に固着されているので、ボルト４３をフレーム３０の下方から取付部材５１およびフレーム３０を通してナット３０Ｎに螺合するだけで防振ゴム２０をフレーム３０に固着できる。次いでキャビン１０内からねじ部２２ａにナット４２を螺合して防振ゴム２０をフロアプレート１１に締結すれば、１個の防振ゴムの取付作業が完了する。交換が必要な防振ゴム２０が他にもある場合には上述と同様の手順で交換する。
【００１０】
このように本実施の形態では、クレーン等の補助機械を一切用いることなく防振ゴムの交換が行えるので、交換作業の効率向上およびコストダウンに寄与する。特に時と場所を選ぶことなく交換が行えるのに加えて、交換不要な防振ゴムに対しては何らの処置を施す必要もないので、従来の方式と比較して極めて有利である。
【００１１】
なお以上では、従来から用いられている防振ゴム２０をそのまま用いるべく取付部材５１を介して防振ゴム２０をフレーム３０Ａに取付けるようにしたが、防振ゴム２０のフランジ２１を側方に延長して直接（取付部材を介さずに）取付けるようにしてもよい。
【００１２】
−第２の実施の形態−
図３および図４により本発明の第２の実施の形態を説明する。
第１の実施の形態は防振ゴム２０をフレーム３０の下方に取り出す構成であったが、本実施の形態は防振ゴム２０をキャビン１０内に取り出すようにしたものである。
図において、キャビン１０のフロアプレート１１Ａには、防振ゴム２０が容易に通る大きさの孔１１ＨＬが形成されている。この孔１１ＨＬを覆うようにフロアプレート１１に配置される取付板６１は、防振ゴム２０のねじ部２２ａが貫通する貫通孔６１Ｈを中央部に有し、外縁部はボルト４４およびナット部１１Ｎによりキャビン１０内からフロアプレート１１Ａに螺着される。孔６１Ｈを貫通するねじ部２２ａにナット４２を螺合することにより防振ゴム２０が取付板６１に螺着される。防振ゴム２０は、フレーム３０の上部から孔３０ＨＬに挿通され、そのフランジ２１がボルト４１およびナット部３０ａによりフレーム３０に螺着される。本実施の形態の取付構造も単一のキャビン１０に対して複数箇所（例えば６箇所）に設けられる。
【００１３】
防振ゴム２０の交換手順を説明する。
交換が必要となった防振ゴム２０に対し、まずキャビン１０内部からナット４２およびボルト４４を外して取付板６１を防振ゴム２０およびフロアプレート１１から取り外す。次いで、キャビン１０内からフロアプレート１１Ａの孔１１ＨＬを介してボルト４１を外し、防振ゴム２０とフレーム３０との連結を解除した後、孔１１ＨＬを通して防振ゴム２０をキャビン１０内に引き上げる。次に新品の防振ゴム２０をキャビン１０内から孔１１ＨＬを介して孔３０ＨＬに挿通し、そのフランジ２１をボルト４１およびナット部３０ａによりフレーム３０に螺着する。その後、防振ゴム２０のねじ部２２ａが孔６１Ｈを貫通するように取付板６１をフロアプレート１１Ａの孔１１ＨＬに被せ、ボルト４４とナット部１１Ｎによりフロアプレート１１Ａに螺着する。最後にねじ部２２ａにナット４２を螺合して防振ゴム２０を取付板６１に締結すれば、取付作業が完了する。交換が必要な防振ゴム２０が他にもある場合には上述と同様の手順で交換する。
【００１４】
本実施の形態においてもクレーン等を用いることなく防振ゴムの交換が行えるので、交換作業の効率向上およびコストダウンに寄与する。
なお以上では、防振ゴム２０と取付板６１との連結を解除してから防振ゴムを取り出すようにしたが、取付板６１が連結されたまま取出し後で取り外すようにしてもよい。ただし、その場合にはボルト４１をキャビン内からでなくフロアプレート１１Ａとフレーム３０との隙間から予め外しておく必要がある。
また第１および第２の実施の形態において、防振部材は防振機能を有するものであれば防振ゴム以外のものでもよい。
【００１５】
【発明の効果】
請求項１の発明によれば、防振部材をフレームの下方からフレームに、キャビン内部からフロアプレートにそれぞれ着脱可能に連結し、防振部材のフロアプレートおよびフレームとの連結を共に解除した状態で防振部材をフレームの下方に取り出し可能に構成したので、クレーン等の補助機械を一切用いることなく防振ゴムの交換が行え、交換作業効率の向上およびコストダウンに寄与する。
請求項２の発明によれば、キャビンのフロアプレートに形成された孔部を覆うようにフロアプレートに着脱可能な取付部材を備え、防振部材をフレームおよび取付部材に着脱可能に連結し、取付部材とフロアプレートとの連結、およびフレーム側連結部とフレームとの連結を共に解除した状態で防振部材を上記孔部からキャビン内部に取り出し可能に構成したので、上述と同様の作用効果が得られる。

BACKGROUND OF THE INVENTION
The present invention relates to a mounting structure for attaching a cabin to a frame of a construction machine via a vibration isolating member, and particularly considers that the vibration isolating member can be easily replaced.
[0002]
[Prior art]
FIG. 5 shows a conventional cabin mounting structure.
In order to suppress transmission of vibrations during work or traveling to the cabin 10, the cabin 10 is attached to the frame 30 of the construction machine via a plurality of vibration isolating rubbers 20. As shown in FIGS. 6 and 7, the anti-vibration rubber 20 has a flange 21 that is screwed to the frame 30 by a bolt 41 and a nut portion 30 a, and a screw portion 22 a that penetrates the floor plate 11 of the cabin 10 from below. The cabin attachment portion 22 is fixed to the floor plate 11 by screwing a nut 42 from the inside of the cabin 10 to the screw portion 22a. In FIG. 5, only one anti-vibration rubber 20 is shown, but actually, it is provided at six locations.
[0003]
If the anti-vibration rubber 20 sags after prolonged use, it must be replaced with a new one. In the conventional mounting structure described above, when replacing the anti-vibration rubber 20, first, the nuts 42 are removed from the screw portions 22 a for all the anti-vibration rubbers 20 and the connection between the anti-vibration rubber 20 and the cabin 10 is released. Lift the cabin 10 using a crane, then remove the bolts 41 to release the connection between the anti-vibration rubber 20 and the frame 30, and pull the anti-vibration rubber 20 one by one into the gap between the floor plate 11 and the frame 30. Take out. After that, a new anti-vibration rubber 20 is attached in the reverse procedure to that described above.
[0004]
[Problems to be solved by the invention]
Thus, in the conventional configuration, a crane is required to replace the anti-vibration rubber 20, which is troublesome and expensive. In particular, in the system in which the cabin 10 is lifted by a crane, it is necessary to release the connection between all the anti-vibration rubbers 20 and the floor plate 11 even when only the anti-vibration rubbers 20 having a heavy sag are to be exchanged, and the work efficiency is extremely poor.
[0005]
An object of the present invention is to provide a cabin mounting structure for a construction machine in which a vibration isolating member can be replaced without using an auxiliary machine such as a crane.
[0006]
[Means for Solving the Problems]
The present invention is applied to a mounting structure in which a cabin is attached to an upper part of a frame constituting a construction machine via a vibration isolation member.
According to the first aspect of the present invention, the vibration isolating member includes a frame side connecting portion that is detachably connected to the frame from below the frame, and a cabin side connecting portion that is detachably connected to the cabin floor plate from the interior of the cabin. The anti-vibration member is integrated with the frame side connection portion and the cabin side connection portion in a state where the connection between the cabin side connection portion and the floor plate and the connection between the frame side connection portion and the frame are both released. In such a state, it can be taken out below the frame.
[0007]
According to a second aspect of the present invention, there is provided an attachment member that is detachably connected to the floor plate from the cabin so as to cover a hole formed in the floor plate of the cabin, and the vibration isolation member is detachably connected to the frame. Frame-side connecting portion and a cabin-side connecting portion that is detachably connected to the mounting member from inside the cabin, and the connection between the mounting member and the floor plate and the connection between the frame-side connecting portion and the frame are both released. In this state, the vibration isolation member can be taken out from the hole into the cabin.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
-First embodiment-
A first embodiment of the present invention will be described with reference to FIGS. In addition, the same code | symbol is attached | subjected to the component similar to FIGS.
The frame 30 is formed with a hole 30H through which the anti-vibration rubber 20 passes, and the floor plate 11 of the cabin 10 is formed with a screw through-hole 11H through which the screw portion 22a of the anti-vibration rubber 20 passes. A pair of attachment members 51 are screwed to the flange 21 of the vibration isolating rubber 20 by bolts 41 and nuts 51N, and each attachment member 51 is screwed to the frame 30 from below the frame 30 by bolts 43 and nuts 30N. Further, the anti-vibration rubber 20 is fastened to the floor plate 11 by screwing the nut 41 into the screw portion 22a that passes through the hole 11H of the floor plate 11. In addition, this attachment structure is provided in multiple places (for example, 6 places) with respect to the single cabin 10 as mentioned above.
[0009]
A procedure for replacing the vibration-proof rubber 20 will be described.
For the anti-vibration rubber 20 that needs to be replaced, first, the nut 42 is removed from the cabin 10 to release the connection between the anti-vibration rubber 20 and the floor plate 11. Next, the bolts 43 are removed from below the frame 30 to release the connection between the vibration isolating rubber 20 and the frame 30. As a result, the anti-vibration rubber 20 with the attachment member 51 attached can be taken out below the frame 30. At this time, since the other anti-vibration rubber 20 is still attached, the cabin 10 does not undesirably descend. Next, the attachment member 51 is attached to the new vibration-proof rubber 20 with the bolt 41 and the nut portion 51N, and the vibration-proof rubber 20 is passed through the hole 30H from below the frame 30. The mounting member 51 is screwed to the frame 30 by the bolts 43 and the nut portions 30N in a state where the screw portions 22a of the cabin side connecting portion 22 pass through the holes 11H of the floor plate 11. Since the nut portion 30N is fixed to the frame 30 in advance, the anti-vibration rubber 20 can be fixed to the frame 30 only by screwing the bolt 43 from below the frame 30 through the mounting member 51 and the frame 30 to the nut 30N. Next, when the nut 42 is screwed into the screw portion 22a from the cabin 10 and the vibration isolating rubber 20 is fastened to the floor plate 11, the installation work of one vibration isolating rubber is completed. If there are other anti-vibration rubbers 20 that need to be replaced, they are replaced in the same manner as described above.
[0010]
As described above, in the present embodiment, the vibration-proof rubber can be replaced without using any auxiliary machine such as a crane, which contributes to improvement in efficiency of the replacement work and cost reduction. In particular, in addition to being able to be replaced without selecting the time and place, it is not necessary to perform any treatment on the vibration-proof rubber that does not require replacement, which is extremely advantageous compared to the conventional system.
[0011]
In the above description, the anti-vibration rubber 20 is attached to the frame 30A via the attachment member 51 so that the conventional anti-vibration rubber 20 can be used as it is. However, the flange 21 of the anti-vibration rubber 20 is extended sideways. And you may make it attach directly (without going through an attachment member).
[0012]
-Second Embodiment-
A second embodiment of the present invention will be described with reference to FIGS.
In the first embodiment, the anti-vibration rubber 20 is taken out below the frame 30, but in the present embodiment, the anti-vibration rubber 20 is taken out into the cabin 10.
In the figure, the floor plate 11A of the cabin 10 is formed with a hole 11HL having a size through which the anti-vibration rubber 20 can easily pass. The mounting plate 61 arranged on the floor plate 11 so as to cover the hole 11HL has a through hole 61H through which the threaded portion 22a of the anti-vibration rubber 20 passes, and an outer edge portion is formed by a bolt 44 and a nut portion 11N. It is screwed from the cabin 10 to the floor plate 11A. The anti-vibration rubber 20 is screwed to the mounting plate 61 by screwing the nut 42 into the screw portion 22a penetrating the hole 61H. The anti-vibration rubber 20 is inserted into the hole 30HL from the upper part of the frame 30, and the flange 21 is screwed to the frame 30 by the bolt 41 and the nut portion 30a. The mounting structure of the present embodiment is also provided at a plurality of locations (for example, 6 locations) with respect to a single cabin 10.
[0013]
A procedure for replacing the vibration-proof rubber 20 will be described.
First, the nut 42 and the bolt 44 are removed from the cabin 10 to remove the mounting plate 61 from the vibration isolating rubber 20 and the floor plate 11. Next, the bolt 41 is removed from the cabin 10 through the hole 11HL of the floor plate 11A to release the connection between the vibration isolating rubber 20 and the frame 30, and then the vibration isolating rubber 20 is pulled into the cabin 10 through the hole 11HL. Next, a new anti-vibration rubber 20 is inserted into the hole 30HL from the cabin 10 through the hole 11HL, and the flange 21 is screwed to the frame 30 by the bolt 41 and the nut portion 30a. Thereafter, the mounting plate 61 is placed on the hole 11HL of the floor plate 11A so that the threaded portion 22a of the vibration isolating rubber 20 penetrates the hole 61H, and is screwed to the floor plate 11A with the bolt 44 and the nut portion 11N. Finally, when the nut 42 is screwed onto the threaded portion 22a and the anti-vibration rubber 20 is fastened to the mounting plate 61, the mounting operation is completed. If there are other anti-vibration rubbers 20 that need to be replaced, they are replaced in the same manner as described above.
[0014]
Also in the present embodiment, the vibration-proof rubber can be replaced without using a crane or the like, which contributes to improvement in efficiency of the replacement work and cost reduction.
In the above description, the anti-vibration rubber is taken out after releasing the connection between the anti-vibration rubber 20 and the mounting plate 61. However, the anti-vibration rubber may be removed after being taken out while the mounting plate 61 is connected. However, in that case, it is necessary to remove the bolts 41 from the gap between the floor plate 11A and the frame 30 in advance, not from the cabin.
In the first and second embodiments, the vibration isolation member may be other than the vibration isolation rubber as long as it has a vibration isolation function.
[0015]
【The invention's effect】
According to the first aspect of the present invention, the vibration isolating member is detachably connected to the frame from the lower side of the frame and from the cabin to the floor plate, and the connection between the vibration isolating member and the floor plate and the frame is released together. Since the anti-vibration member is configured to be able to be taken out below the frame, the anti-vibration rubber can be replaced without using any auxiliary machine such as a crane, which contributes to an improvement in replacement work efficiency and cost reduction.
According to the invention of claim 2, the mounting member is detachably attached to the floor plate so as to cover the hole formed in the floor plate of the cabin, and the vibration isolating member is detachably connected to the frame and the mounting member. Since the vibration isolation member can be taken out from the hole into the cabin in a state where the connection between the member and the floor plate and the connection between the frame side connection portion and the frame are both released, the same effect as described above can be obtained. It is done.
