Description

本発明は防振架台に関し、特に、ガスエンジン等の振動発生源を内蔵する重量機器の設置に好適な防振架台に関する。   The present invention relates to an anti-vibration mount, and more particularly, to an anti-vibration mount suitable for installation of heavy equipment including a vibration source such as a gas engine.

従来、防振架台に関しては、搬送の困難性、機器振動による長期使用時の締付具緩みによるガタツキ発生等の問題が指摘されていた。これを解消する防振架台として、金属製の上枠と下枠の間に吸振部材(バネ)を介装し、さらに転倒防止を兼ねる連結部材により上枠と下枠を接続する技術が開示されている(例えば特許文献1)。しかし、特許文献1の防振架台では、現場組み立ての困難性、構造上から来る運転時の反響音拡大、防振部材の外気露出による耐久性の点で課題があった。
本願発明者らは、このような課題を解決するための防振架台を提案している(特許文献2)。図11に示すように特許文献2の防振架台100は、既設の設置基礎105の上に、吸振部材102を介して載置される架台本体101により構成されている。吸振部材102の上端部は架台本体101の底面凹部101aに収容され、下端部は設置基礎105上面の貫通孔105aに嵌合され保持される。振動発生源である機器108は、固定用部材108aにより架台本体101上に固定設置される。機器108は、設置基礎105の両端部に取り付けられた転倒防止部材103により、架台本体101と一体に位置変動が規制される。
Conventionally, with respect to the vibration isolator, problems such as difficulty in transport and looseness due to loosening of fasteners during long-term use due to equipment vibration have been pointed out. As a vibration isolator that solves this problem, a technique is disclosed in which a vibration absorbing member (spring) is interposed between a metal upper frame and a lower frame, and the upper frame and the lower frame are connected by a connecting member that also serves to prevent falling. (For example, Patent Document 1). However, the vibration isolator of Patent Document 1 has problems in terms of the difficulty in assembling at the site, the expansion of reverberant sound during operation that comes from the structure, and the durability due to exposure of the vibration isolator to the outside air.
The inventors of the present application have proposed a vibration isolator for solving such problems (Patent Document 2). As shown in FIG. 11, the vibration isolator 100 of Patent Document 2 is composed of a base body 101 placed on an existing installation base 105 via a vibration absorbing member 102. The upper end portion of the vibration absorbing member 102 is accommodated in the bottom surface recess 101 a of the gantry body 101, and the lower end portion is fitted and held in the through hole 105 a on the upper surface of the installation base 105. The device 108 as a vibration source is fixedly installed on the gantry body 101 by a fixing member 108a. The position fluctuation of the device 108 is regulated integrally with the gantry body 101 by the fall prevention members 103 attached to both ends of the installation base 105.

Referring to FIG. 2, the upper frame 2 is made of concrete and formed in a thin plate shape, and four vibration absorbing member accommodation holes 2 c for accommodating the vibration absorbing members 4 are provided at the four corners of the lower surface. The vibration absorbing member accommodation hole 2c is penetrated in a truncated cone shape so that the vibration absorbing member 4 is always accommodated in an upright state. At the four corners of the upper surface 2a, mounting holes 2d for fixing the device 8 are formed, and fixing anchor plugs (not shown) are respectively driven. In the center of the side surface 2e, there is provided a fall prevention member accommodation hole 2f that can accommodate the claw portion 5b of the fall prevention member 5 with sufficient play. In addition, in order to increase bending strength and tensile strength, the upper frame 2 can also be provided with a reinforcing bar (the same applies to the basic frame 3).

図3を参照して、基礎架台3は上部架台2と同一寸法に構成され、その上面3aの四隅には、吸振部材4を嵌入するためのセンターピン取付孔3cが穿けられている。取付孔3cには、不図示のアンカープラグが嵌入されている。センターピン取付孔3cは、上部架台2の吸振部材収容孔2cと機器設置状態において、中心軸が共通となる位置に設けられている。左右の側面3eには、転倒防止部材5固定のための一対の取付孔3dが穿けられている。   Referring to FIG. 3, the foundation frame 3 is configured to have the same dimensions as the upper frame 2, and center pin mounting holes 3 c for fitting the vibration absorbing members 4 are formed in the four corners of the upper surface 3 a. An anchor plug (not shown) is fitted into the mounting hole 3c. The center pin mounting hole 3c is provided at a position where the central axis is common in the device installation state with the vibration absorbing member accommodation hole 2c of the upper frame 2. A pair of attachment holes 3d for fixing the fall prevention member 5 is formed in the left and right side surfaces 3e.

基礎架台上面3aの縁部周囲には、シール部材6が接着固定されている。後述するように機器設置状態において、上部架台2と基礎架台3の間に形成される空間を密閉可能とするように配設されている。シール部材6の材質としては、例えばエプトシーラー(登録商標)等の耐候性吸音シートを用いることができ、   A seal member 6 is bonded and fixed around the edge of the upper surface 3a of the foundation frame. As will be described later, in the equipment installation state, the space formed between the upper frame 2 and the foundation frame 3 is disposed so as to be hermetically sealed. As a material of the seal member 6, for example, a weather-resistant sound absorbing sheet such as EPT SEALER (registered trademark) can be used,

図4を参照して、吸振部材4は、吸振機能を備えた円柱形状の吸振体41と、吸振体41の上部突起部41dに嵌合し、かつ収容孔2cの底面に当接して防振機能を強化するゴムリング42と、基礎架台3の取付孔3cに螺合固定されるセンターピン44と、吸振体41の内側筒状空間41cとセンターピン44の間に介装される振動緩衝用保護スリーブ43と、により構成されている。保護スリーブ43材質としては、例えば塩ビエラストマーを用いることができる。
吸振体41は、弾性体(バネ)41aをサージング防止機能を有する粘弾性材料41bでモールドした構造を備えている。吸振体41の粘弾性材料41b及びゴムリング42材料としては、それぞれ例えばNBR,EPDMを用いることができる。
なお、本実施形態では、吸振体41の上部にゴムリング42を被せる構成としたが、吸振体の頂部が収容孔2cの底面に当接する構成としてもよい。
Referring to FIG. 4, the vibration absorbing member 4 is fitted to the columnar vibration absorber 41 having a vibration absorbing function and the upper protrusion 41 d of the vibration absorber 41 and is in contact with the bottom surface of the accommodation hole 2 c to prevent vibration. A rubber ring 42 that strengthens the function, a center pin 44 that is screwed into the mounting hole 3 c of the foundation frame 3, and a vibration buffer that is interposed between the inner cylindrical space 41 c of the vibration absorber 41 and the center pin 44. And a protective sleeve 43. As the material of the protective sleeve 43, for example, a vinyl chloride elastomer can be used.
The vibration absorber 41 has a structure in which an elastic body (spring) 41a is molded with a viscoelastic material 41b having a function of preventing surging. As the viscoelastic material 41b and the rubber ring 42 material of the vibration absorber 41, for example, NBR and EPDM can be used, respectively.
In the present embodiment, the rubber ring 42 is covered on the top of the vibration absorber 41. However, the top of the vibration absorber may be in contact with the bottom surface of the accommodation hole 2c.

図5を参照して、転倒防止部材5は、基礎架台3の両端部に設けた取付孔3dに固定される基礎架台固定部5aと、転倒防止部材5の収容孔2fに遊嵌される爪部5bと、がアングル形状に構成されている。
なお、本実施形態では、転倒防止部材5は90度回転させることにより、後述するアンカーブラケット7としても用いられる。そのため、固定部5a及び爪部5bには、基礎架台3又はコンクリート土間9への固定用ボルト挿通のための一対のボルト孔5c、5dがそれぞれ設けられている。
Referring to FIG. 5, the fall prevention member 5 includes a claw that is loosely fitted in a base frame fixing portion 5 a that is fixed to mounting holes 3 d provided at both ends of the base frame 3 and a receiving hole 2 f of the fall prevention member 5. The part 5b is configured in an angle shape.
In the present embodiment, the fall prevention member 5 is also used as an anchor bracket 7 to be described later by rotating 90 degrees. Therefore, a pair of bolt holes 5c and 5d are provided in the fixing portion 5a and the claw portion 5b for inserting the fixing bolt into the foundation frame 3 or the concrete soil space 9, respectively.

防振架台1は以上のように構成されており、次に、防振架台1及び機器8をコンクリート土間上に設置する場合の設置方法について説明する。図6を参照して、
(a)設置に先行して、水平に調整したコンクリート土間9の所定位置に、基礎架台3を固定するための取付孔9aを穿け、アンカープラグ(図示せず)を打ち込んで置く。
(b)次いで、取付孔9aにアンカーブラケット7をボルト7aで仮固定する。
(c)基礎架台3をコンクリート土間9に配置し、ボルト5dで転倒防止部材5を基礎架台3に仮固定する。その際、スペーサーとして、アンカーブラケット7を基礎架台3と転倒防止部材5の間に介在させる。次いで、基礎架台3上面に、センターピン44を取り付ける。
(d)次に、吸振部材4をセンターピン44に差し込む。
The anti-vibration mount 1 is configured as described above. Next, an installation method in the case where the anti-vibration mount 1 and the device 8 are installed on the concrete soil will be described. Referring to FIG.
(A) Prior to installation, a mounting hole 9a for fixing the foundation gantry 3 is drilled at a predetermined position of the concrete soil 9 adjusted horizontally, and an anchor plug (not shown) is driven and placed.
(B) Next, the anchor bracket 7 is temporarily fixed to the mounting hole 9a with a bolt 7a.
(C) The foundation gantry 3 is placed in the concrete soil 9, and the toppling prevention member 5 is temporarily fixed to the foundation gantry 3 with bolts 5 d. At that time, the anchor bracket 7 is interposed between the foundation frame 3 and the fall prevention member 5 as a spacer. Next, the center pin 44 is attached to the upper surface of the foundation frame 3.
(D) Next, the vibration absorbing member 4 is inserted into the center pin 44.

図7を参照して、次いで吸振部材4が収容孔2cに収容されるように、上部架台2を基礎架台3の上に載置する。載置後に、転倒防止部材5の爪部5bが上部架台2の転倒防止部材収容孔2f内に遊びを以って挿入する位置で、転倒防止部材5を基礎架台3に固定する。最後に機器8を上部架台2上に載置し、固定ボルト8bにより機器脚部8aを上部架台2に固定して設置が完了する。   With reference to FIG. 7, the upper frame 2 is then placed on the foundation frame 3 so that the vibration absorbing member 4 is accommodated in the accommodation hole 2 c. After the placement, the tipping prevention member 5 is fixed to the base stand 3 at a position where the claw portion 5b of the tipping prevention member 5 is inserted into the tipping prevention member accommodation hole 2f of the upper stand 2 with play. Finally, the device 8 is placed on the upper frame 2, and the device legs 8 a are fixed to the upper frame 2 with the fixing bolts 8 b to complete the installation.

図8を参照して、転倒防止部材5はアンカーブラケット7を介して基礎架台3に固定されるため、転倒防止部材5が上部架台2に直接接触することはない。これにより、上部架台2を介しての機器8からの振動が直接、基礎架台3に伝わることなく、吸振部材4に吸収されて減衰する。このため、機器振動の影響を大幅に減少させることが可能となる。   Referring to FIG. 8, since the fall prevention member 5 is fixed to the base frame 3 via the anchor bracket 7, the fall prevention member 5 does not directly contact the upper frame 2. As a result, vibration from the device 8 through the upper mount 2 is not directly transmitted to the base mount 3 but is absorbed and attenuated by the vibration absorbing member 4. For this reason, it becomes possible to reduce the influence of apparatus vibration significantly.

また、図9を参照して、上部架台2の吸振部材収容孔2cは上述のように円錐台形状に構成されており、表面口径d1>底面口径d2である。また、吸振部材4のゴムリング42の上面外径は、収容孔2cの底面口径d2より僅かに大きい程度(1〜2mm程度)であるため、振動により上部架台2が左右に変位しても速やかに、ゴムリング42の上面全体が底面2gに当接した状態に復帰保持される。これにより、吸振部材4の吸振機能を常に保持することができる。   Referring to FIG. 9, the vibration absorbing member accommodation hole 2c of the upper pedestal 2 is configured in a truncated cone shape as described above, and the surface diameter d1> the bottom surface diameter d2. Further, since the outer diameter of the upper surface of the rubber ring 42 of the vibration absorbing member 4 is slightly larger (about 1 to 2 mm) than the bottom diameter d2 of the accommodation hole 2c, it can be promptly moved even if the upper frame 2 is displaced left and right due to vibration. In addition, the entire upper surface of the rubber ring 42 is returned and held in contact with the bottom surface 2g. Thereby, the vibration absorbing function of the vibration absorbing member 4 can always be maintained.

なお、本実施形態では上部架台2を基礎架台3の四隅に配設した4個の吸振部材4で支持する例を示したが、さらに多くの吸振部材を吸振部材で支持して、吸振性能を向上させる態様とすることもできる。   In the present embodiment, the example in which the upper frame 2 is supported by the four vibration absorbing members 4 arranged at the four corners of the foundation frame 3 is shown. However, more vibration absorbing members are supported by the vibration absorbing members, and the vibration absorbing performance is improved. It can also be set as the aspect improved.

(第二の実施形態)
さらに、本発明の他の実施形態について説明する。本実施形態は防振架台をコンクリート土間ではなく、地面上に直接設置する態様に係る。防振架台本体の構成は第一の実施形態と同一であるので、重複説明を省略する。
図9は、本実施形態における防振架台20設置状態の側面端部詳細構成を示す図である。本実施形態では、地表面を僅かに削って水平面21aを形成し、アンカーブラケットを用いることなく、水平面21a上に基礎架台3を配置する。転倒防止部材5は、スペーサー22を介してボルト23により基礎架台3に固定される。スペーサー22の介装により、転倒防止部材5が上部架台2に接触することなく基礎架台3に固定することができる。転倒防止部材収容孔2fへの爪部5bの遊嵌の態様については、上述の実施形態と同一である。その他の構成についても、吸振部材4の収容状態、機器固定態様等を含め上述の実施形態と同一であるので、重複説明を省略する。
(Second embodiment)
Furthermore, another embodiment of the present invention will be described. This embodiment concerns the aspect which installs a vibration isolator stand directly on the ground instead of between concrete soils. Since the structure of the anti-vibration mount main body is the same as that of the first embodiment, redundant description is omitted.
FIG. 9 is a diagram showing a detailed configuration of the side end portion in the installed state of the vibration isolator 20 in the present embodiment. In the present embodiment, the ground surface is slightly shaved to form the horizontal surface 21a, and the foundation frame 3 is disposed on the horizontal surface 21a without using an anchor bracket. The fall prevention member 5 is fixed to the foundation frame 3 with a bolt 23 via a spacer 22. The fall prevention member 5 can be fixed to the base frame 3 without contacting the upper frame 2 by the interposition of the spacer 22. About the loose fitting aspect of the nail | claw part 5b to the fall prevention member accommodation hole 2f, it is the same as the above-mentioned embodiment. Other configurations are also the same as those in the above-described embodiment including the accommodation state of the vibration absorbing member 4, the device fixing mode, and the like, and thus the redundant description is omitted.

本発明はガスエンジン発電機に限らず、振動発生源を内蔵する重量機器用の防振架台として広く適用可能である。   The present invention is not limited to a gas engine generator and can be widely applied as a vibration isolator for heavy equipment having a built-in vibration source.
