Description
【0001】[0001]
この考案は、直線状の架台を並行に設置して使用する防振遮音架台に関する。 The present invention relates to a vibration-proof and sound-insulating pedestal in which linear pedestals are installed in parallel and used.
【0002】[0002]
従来の防振架台は、図6に示すようにストッパ4で上架台の転倒防止と最大高 さを規制された上架台1と下架台2との間に複数の吸振体3を移動調節可能に挟 着したものであって、吸振効果を高めるために吸振体に内装されるバネをバネ定 数一定のコイルバネとしていた。 このため搭載機械が例えば揚水ポンプなどの場合、ポンプの起動時毎に激しい沈 み込みが起こり、接続されている配管に無理な力を与える欠点があった。 更に上記装置は、吸振体3の位置調節が面倒である他、外筐3a,3bを介して 下架台2と床に振動や音が伝達される欠点もある。 As shown in FIG. 6, in the conventional vibration-proof frame, a plurality of vibration-absorbing bodies 3 can be adjusted between the upper frame 1 and the lower frame 2 whose stoppers 4 prevent the upper frame from falling and the maximum height is restricted. In order to enhance the vibration absorption effect, the springs incorporated in the vibration absorber were coil springs with a constant spring constant. For this reason, when the installed machine is, for example, a pump for pumping, there is a drawback that a severe depression occurs every time the pump is started, and an unreasonable force is applied to the connected piping. Further, the above-mentioned device has the drawback that the position adjustment of the vibration absorber 3 is troublesome and that vibrations and sounds are transmitted to the lower pedestal 2 and the floor via the outer casings 3a and 3b.

本案は、大きな衝撃荷重に対しても上架台の上下動が少なく接続配管にも影響 を与えない防振遮音架台を提供するものであり、更に吸振体の位置調節などの操 作を不要にした架台を提供するものである。 This plan provides a vibration and sound insulation mount that does not cause vertical movement of the upper mount even with a large impact load and does not affect the connection piping.In addition, operations such as position adjustment of the vibration absorber are unnecessary. It provides a mount.

本案防振遮音架台は、一対の並行架台を構成する各下架台上の両端に側面を開 口させた台枠を突設すると共に前記各台枠上に円錐コイルバネ等の非直線性コイ ルバネをストッパボルト挿通用孔の周囲に対称的に複数個配設すると共にこれら 各バネを弾性ゴム製錐台状筐体内に包持収容されてなる吸振装置が設けられ、上 架台下面に突設固定したストッパボルトが前記防振装置のボルト挿通孔及び前記 台枠を貫通してクッション体を介してナット締結されて構成されている。 本案防振架台に使用される吸振装置は図の如く連接体とされている必要はなく1 個のバネを1個の弾性ゴム製錐台状筐体内に包持収容させたものでもよい。 ストッパボルトの周囲に対称的に配設される非直線性バネの個数は3〜4個であ る。 The anti-vibration and sound insulation mount of the present invention has a frame with open side faces projecting from both ends on each lower frame that constitutes a pair of parallel frames, and a non-linear coil spring such as a conical coil spring is mounted on each frame. A plurality of symmetrically arranged springs are provided around the stopper bolt insertion hole, and a vibration absorbing device is provided in which each of these springs is enclosed and housed in an elastic rubber frustum-shaped housing, and is fixed to the lower surface of the upper stand by projecting. The stopper bolt penetrates the bolt insertion hole of the vibration isolator and the underframe and is fastened with a nut via a cushion body. The vibration absorbing device used in the vibration isolating mount of the present invention does not have to be a connecting body as shown in the figure, and one spring may be housed and contained in one elastic rubber frustum-shaped casing. The number of non-linear springs symmetrically arranged around the stopper bolt is 3 to 4.

本案装置は上記の構成であるから簡単に製作できる上、本案装置における吸振 装置は非直線性コイルバネを内装しているから大荷重に対する変形量が僅かであ る他、バネの上下面及び全周を弾性ゴム体で囲繞されているので遮音性に優れて おり上下架台を振動及び音響的に完全に絶縁している。 また、吸振装置を連接体でなく個別に配設する場合でも製作後に位置調節する必 要は全くないものである。 更に台枠の両側面が開口されているので上架台のレベル又はバネの予圧調節が簡 単にできる効果がある。 Since the device of the present invention has the above-mentioned configuration, it can be easily manufactured, and since the vibration absorber in the device of the present invention has a non-linear coil spring built-in, the amount of deformation with respect to a large load is small, and the upper and lower surfaces of the spring and the entire circumference are Since it is surrounded by an elastic rubber body, it has excellent sound insulation and completely isolates the upper and lower pedestals from vibration and acoustics. Further, even if the vibration absorbers are individually arranged instead of being connected to each other, there is no need to adjust the position after manufacturing. Furthermore, since both sides of the underframe are opened, it is possible to easily adjust the level of the upper frame or the preload of the spring.

図において10は上架台であって各端部下面にストッパボルト11が垂設固定 されている。 20は下架台であって、両端部上面に側面に開口部22を設けたコ状の台枠21 が固設されている。 23は、台枠の上板、24はストッパボルト挿通孔である。 台枠は下架台の一部を打抜いた残部材で成形できる他、台枠21と固定用耳片2 1aと共に成形することもできる。 25は、吸振装置であって、円錐コイルバネその他の非直線性コイルバネ26を 3〜4個、ボルト挿通用孔27を中心にして対称的に配設すると共にこれら各バ ネを弾性ゴム製錐台状筐体28内に包持する如く収容したものである。 従って円錐コイルバネ26は、上面、下面及び全周を弾性ゴムによって囲繞され て台枠の上板23上に定置されている。 図は、錐台状筐体を4連接したものの例であって、筐体の共通台板部29は方形 に成型されている。 ストッパボルト11は弾性ゴム筐体のボルト挿通用孔27及び台枠の挿通孔24 を貫通して台枠上板の下面に突出しクッション体12を介して調節ナット13に よって締結されている。 ナット13は側面開口部22から簡単に回動調節できる。 In the figure, reference numeral 10 denotes an upper mount, and stopper bolts 11 are vertically fixed to the lower surface of each end. Reference numeral 20 denotes a lower mount, and a U-shaped base frame 21 having openings 22 on the side surfaces is fixedly provided on the upper surfaces of both ends. Reference numeral 23 is an upper plate of the underframe, and 24 is a stopper bolt insertion hole. The underframe can be formed by a remaining member obtained by punching out a part of the lower frame, or can be formed together with the underframe 21 and the fixing ear piece 21a. Reference numeral 25 denotes a vibration absorbing device, in which 3 to 4 conical coil springs and other non-linear coil springs 26 are symmetrically arranged around the bolt insertion hole 27 and each of these panels is made of an elastic rubber frustum. The housing 28 is housed so as to be wrapped. Therefore, the conical coil spring 26 is fixed on the upper plate 23 of the underframe by surrounding the upper surface, the lower surface and the entire circumference with elastic rubber. The figure shows an example of four frustum-shaped casings connected in series, and the common base plate portion 29 of the casing is formed in a rectangular shape. The stopper bolt 11 penetrates the bolt insertion hole 27 of the elastic rubber housing and the insertion hole 24 of the underframe to protrude to the lower surface of the underframe upper plate, and is fastened by the adjusting nut 13 via the cushion body 12. The nut 13 can be easily rotated and adjusted from the side opening 22.
