Abstract
A pump support mechanism (2) of a pump device (1) supports a pump rack (4) on which a pump (3) is mounted by a base frame (6) via a rubber vibration isolator (5). A boss (7) on the pump rack (4) side of the pump support mechanism (2) abuts against an inner peripheral edge (81) of a boss hole (8) on the base frame (6) side to restrict the swinging of the pump (3) during pump transportation or the like, thereby preventing damage to the rubber vibration isolator (5). A bolt (9) fixed to the boss (7) on the pump rack (4) side hits a frame back side (64) of the base frame (6) to inhibit a spacing between the pump rack (4) and the base frame (6) from expanding, thereby restricting the stretch of the rubber vibration isolator (5). During the pump operation, the bolt (9) is spaced apart downward from the frame back side (64), and hence a function for suppressing vibration noise by the rubber vibration isolator (5) is not inhibited.
Description
本発明は、防振ゴムを介してポンプを支持するポンプ支持機構、および当該ポンプ支持機構を備えたポンプ装置に関する。
The present invention relates to a pump support mechanism that supports a pump via anti-vibration rubber, and a pump device equipped with the pump support mechanism.
ドライ真空ポンプ等のポンプは、一般的に、防振ゴムを介してベースフレームに据え付けられ、運転時等における振動騒音を抑制している。ポンプは、防振ゴムを介してベースフレームに支持された状態で輸送等されて、ポンプ設置場所に設置される。例えば、図４に示すように、ポンプ１００が搭載されたポンプ架台１１０の脚部１１１が、防振ゴム１２０を挟み、ベースフレーム１３０に取り付けられる。防振ゴム１２０は、ポンプ架台１１０の脚部１１１の裏面から下方に垂直に延びる軸１４０に沿って上下方向に伸縮可能に配置されている。ポンプ１００の輸送時等においては、ポンプ架台１１０と、ベースフレーム１３０との間に固定ブラケット１５０を取り付けて、防振ゴム１２０によって支持されているポンプ架台１１０に搭載されたポンプ１００に揺れが生じないようにしている。
Pumps such as dry vacuum pumps are generally installed on the base frame via anti-vibration rubber to suppress vibration noise during operation. The pump is transported while being supported by the base frame via anti-vibration rubber, and installed at the pump installation site. For example, as shown in FIG. 4, the legs 111 of the pump frame 110 on which the pump 100 is mounted are attached to the base frame 130 with anti-vibration rubbers 120 interposed therebetween. The anti-vibration rubber 120 is arranged so as to be vertically extendable along a shaft 140 vertically extending downward from the rear surface of the leg portion 111 of the pump base 110 . When the pump 100 is transported or the like, the fixing bracket 150 is attached between the pump base 110 and the base frame 130, and the pump 100 mounted on the pump base 110 supported by the anti-vibration rubber 120 is shaken. I try not to
固定ブラケット１５０は、ポンプ輸送時等における防振ゴム１２０の弾性変形に起因するポンプの揺れを防止し、防振ゴムに過剰な力が加わって破断するなどの弊害を防止している。また、トラックなどの荷台からポンプを吊り上げる際に、防振ゴムが過剰に引き伸ばされてしまうことを防止している。ポンプ設置後は固定ブラケットが取り外される。固定ブラケットを取り外さないと、防振ゴムが機能せず振動騒音を抑制できない。
The fixing bracket 150 prevents the vibration of the pump due to elastic deformation of the rubber vibration isolator 120 during transportation of the pump, and prevents damage such as breakage due to excessive force being applied to the rubber vibration isolator. In addition, it prevents the anti-vibration rubber from being excessively stretched when the pump is lifted from a loading platform such as a truck. After installing the pump, the fixing bracket is removed. If the fixing bracket is not removed, the anti-vibration rubber will not function and the vibration noise cannot be suppressed.
ここで、特許文献１に記載の圧縮機搭載機器では、圧縮機の脚部が、ボルト、ナットにより底フレームに取り付けられ、ボルトを同軸に取り囲む状態で、脚部と底フレームとの間に防振ゴムが挟み込まれている。ボルトには、圧縮機転倒防止用のストッパが取り付けられている。輸送時において、防振ゴムが大きく変形する前に、ストッパが脚部に当たり、防振ゴムの過度の変形が抑制され、圧縮機の横転が防止される。ストッパは、通常の状態では、脚部から離れており、防振ゴムの伸縮（防振機能）を阻害しないようになっているので、ストッパを取り外すことなく圧縮機を稼働させることができる。特許文献２においても同様な機構を備えた空気調和機の室外ユニットが記載されている。
Here, in the compressor-mounted equipment described in Patent Document 1, the legs of the compressor are attached to the bottom frame with bolts and nuts, and the bolts are coaxially encircled, and a barrier is provided between the legs and the bottom frame. The vibration rubber is sandwiched. A stopper for preventing overturning of the compressor is attached to the bolt. During transportation, the stopper hits the leg portion before the vibration isolator is deformed significantly, suppressing excessive deformation of the vibration isolator and preventing the compressor from overturning. In a normal state, the stopper is separated from the leg so as not to interfere with the expansion and contraction of the vibration-isolating rubber (anti-vibration function), so the compressor can be operated without removing the stopper. Patent Document 2 also describes an outdoor unit of an air conditioner having a similar mechanism.
図４に示すポンプ支持機構においては、固定ブラケットの取付け・取り外しが必要であり煩雑である。固定ブラケット等のポンプ固定部材を必要とすることなく、輸送時等においてポンプを固定でき、防振ゴムの破損や過剰な伸びを防止できることが望ましい。
In the pump support mechanism shown in Fig. 4, it is necessary to attach and detach the fixing bracket, which is complicated. It is desirable to be able to fix the pump during transportation or the like without requiring a pump fixing member such as a fixing bracket, and to prevent breakage and excessive elongation of the anti-vibration rubber.
一方、特許文献１、２に記載の機構では、輸送時に取付け、輸送後に取り外しが必要な部品が不要となる。しかしながら、輸送時等においてポンプに過度の横揺れが生じると、防振ゴムに過剰な力が加わり、防振ゴムが破損あるいは破断するおそれがある。また、配管、ベローズ等のポンプ接続部材に過剰な負荷が掛かり、これらの部材に破損が生じるおそれがある。さらに、パネル等のポンプの周辺に配置されている周辺部材にポンプが接触して、これら周辺部材あるいはポンプに損傷が生じるおそれがある。
On the other hand, the mechanisms described in Patent Documents 1 and 2 do not require parts that must be attached during transportation and removed after transportation. However, if the pump is shaken excessively during transportation or the like, an excessive force is applied to the anti-vibration rubber, and there is a risk that the anti-vibration rubber will be damaged or broken. In addition, an excessive load is applied to pump connection members such as pipes and bellows, and these members may be damaged. Furthermore, there is a risk that the pump will come into contact with peripheral members, such as a panel, that are arranged around the pump, causing damage to these peripheral members or the pump.
本発明の目的は、このような点に鑑みて、ポンプの輸送時、吊り上げ等に、ポンプ固定用の部材を別途取り付けることなく、ポンプの揺れ、防振ゴムの破断・伸び等を回避できるポンプ支持機構、および当該ポンプ支持機構を備えたポンプ装置を提供することにある。
In view of these points, the object of the present invention is to provide a pump that can avoid vibration of the pump, breakage and elongation of anti-vibration rubber, etc., without separately attaching a member for fixing the pump when the pump is transported or lifted. An object of the present invention is to provide a support mechanism and a pump device having the pump support mechanism.

A gap dimension in the vertical direction between the pump stand and the base frame in which the anti-vibration rubber is sandwiched and spanned between the pump stand and the base frame at a position different from the anti-vibration rubber. is equipped with a regulating member that regulates the

The stopper is attached to the protruding end of the boss so as to engage with the other member when the gap dimension increases to the set dimension.
ここで、前記ストッパとして、前記ボスの突出端の端面に開口するネジ穴に同軸にねじ込み固定されたボルトを用いることができる。前記ボルトとして、その頭部の外径が前記ボス穴の穴径よりも大きいものを用いる。
Here, as the stopper, a bolt that is coaxially screwed into a screw hole that opens in the end face of the protruding end of the boss can be used. As the bolt, a bolt whose head has an outer diameter larger than the hole diameter of the boss hole is used.
本発明のポンプ支持機構においては、ポンプ架台およびベースフレームのうちの一方の部材に取り付けたボスが他方の部材に形成したボス穴の内周縁に当接して、ポンプ輸送時等におけるポンプの過度な揺れが制限され、防振ゴムには過剰な力が作用しない。また、ポンプの吊り上げ時等においては、ストッパによって、ポンプ架台とベースフレームとの間の隙間寸法が設定寸法以上に広がることが防止され、防振ゴムの伸びが制限される。さらに、ストッパは隙間寸法が設定寸法未満の状態ではポンプ架台あるいはベースフレームから離れているので、ポンプ運転時における防振ゴムの振動騒音の抑制機能が阻害されることがない。
In the pump support mechanism of the present invention, the boss attached to one member of the pump frame and the base frame abuts against the inner peripheral edge of the boss hole formed in the other member, causing excessive pump movement during transportation of the pump. Shaking is limited and excessive force does not act on the anti-vibration rubber. Further, when the pump is lifted, the stopper prevents the gap between the pump mount and the base frame from expanding beyond the set size, thereby limiting the expansion of the vibration-proof rubber. Furthermore, since the stopper is separated from the pump mount or the base frame when the gap dimension is less than the set dimension, the function of suppressing vibration noise of the rubber vibration isolator during operation of the pump is not hindered.
本発明のポンプ支持機構を用いることにより、ポンプ輸送時等におけるポンプの過度な揺れが制限されるので、防振ゴムの破断、過剰な引き伸ばしを防止できる。また、ポンプ接続部材（配管、ベローズ）に過剰な負荷が加わることが防止されるので、ポンプ接続部材の破損を防止できる。さらに、ポンプがポンプ周辺部材（パネル等）に接触することが防止されるので、接触に起因するポンプ、周辺部材の損傷も防止できる。
By using the pump support mechanism of the present invention, excessive swinging of the pump during pump transportation, etc. is restricted, so breakage and excessive stretching of the anti-vibration rubber can be prevented. Moreover, since excessive load is prevented from being applied to the pump connecting member (pipe, bellows), damage to the pump connecting member can be prevented. Furthermore, since the pump is prevented from coming into contact with pump peripheral members (panels, etc.), damage to the pump and peripheral members due to contact can be prevented.

図２も参照して、ポンプ支持機構２について説明する。ポンプ架台４の４本の脚部４２の水平な底面４３には、下方に向けて円筒状のボス７が垂直に延びている。ボス７の上端部７１（取付け端）に形成した大径の円盤状のフランジ７１ａは、ポンプ架台４の脚部４２の底面４３を規定している底板部分に固定されている。ポンプ架台４の下側のベースフレーム６は、そのフレーム天板部分６１における四隅に、ボス７と同軸の位置に、それぞれ円形のボス穴８が形成されている。ボス穴８はフレーム天板部分６１を上下方向に貫通している。ボス穴８の穴径は、ボス７の外径よりも一回り大きい。ボス７の下端部７２は、フレーム天板部分６１の天面６３側から、ボス穴８を遊びのある状態で貫通して、そのフレーム裏面６４の側に突出している。ポンプ架台４がベースフレーム６に対して横方向にずれると、ポンプ架台４側のボス７が、ベースフレーム６側のボス穴８の内周縁８１に当接して、ポンプ架台４側の横ずれが制限される。ボス穴８の内周縁８１と、ボスの下端部７２との間に形成される隙間寸法Ｄ１は、ポンプ重量、防振ゴム５の弾性特性等に基づき、適切な値に設定される。
The pump support mechanism 2 will be described with reference to FIG. 2 as well. A cylindrical boss 7 vertically extends downward from the horizontal bottom surface 43 of the four legs 42 of the pump mount 4 . A large-diameter disc-shaped flange 71 a formed on the upper end 71 (mounting end) of the boss 7 is fixed to the bottom plate portion defining the bottom surface 43 of the leg 42 of the pump base 4 . Circular boss holes 8 are formed at the four corners of the frame top plate portion 61 of the base frame 6 on the lower side of the pump mount 4 at positions coaxial with the bosses 7 . The boss hole 8 penetrates the frame top plate portion 61 in the vertical direction. The hole diameter of the boss hole 8 is one size larger than the outer diameter of the boss 7 . A lower end portion 72 of the boss 7 penetrates the boss hole 8 with play from the top surface 63 side of the frame top plate portion 61 and protrudes toward the frame back surface 64 side. When the pump mount 4 is displaced laterally with respect to the base frame 6, the bosses 7 on the pump mount 4 side come into contact with the inner peripheral edges 81 of the boss holes 8 on the base frame 6 side, thereby limiting lateral displacement of the pump mount 4 side. be done. A gap dimension D1 formed between the inner peripheral edge 81 of the boss hole 8 and the lower end portion 72 of the boss is set to an appropriate value based on the weight of the pump, the elastic characteristics of the rubber vibration isolator 5, and the like.
ボス７の下端部７２（突出端）は、ボス穴８から、フレーム裏面６４の側に所定の距離だけ突出している。ボス７の下端部７２の端面には、ねじ穴が開口しており、ここには、下側から同軸に、ストッパとして機能するボルト９がねじ込み固定されている。ボルト９の頭部外径は、ボス穴８よりも一回り大きく、上昇すると、フレーム裏面６４に対して下側から係合可能である。ボルト９は、ボス７の抜け止めとして機能し、また、ポンプ架台４とベースフレーム６との間の上下方向の隙間寸法が設定寸法以上に広がることのないように、ベースフレーム６を下側から支持する。このように、ボルト９が取り付けられたボス７は、防振ゴム５が挟み込まれているポンプ架台４とベースフレーム６との間の隙間寸法Ｄ０を設定寸法以下に規制する規制部材として機能する。
A lower end portion 72 (protruding end) of the boss 7 protrudes from the boss hole 8 toward the rear surface 64 of the frame by a predetermined distance. A screw hole is opened in the end surface of the lower end portion 72 of the boss 7, and a bolt 9 functioning as a stopper is coaxially screwed into the hole from below. The outer diameter of the head of the bolt 9 is slightly larger than that of the boss hole 8, and when raised, it can be engaged with the rear surface 64 of the frame from below. The bolt 9 functions as a retainer for the boss 7, and also prevents the vertical gap between the pump mount 4 and the base frame 6 from expanding beyond a set dimension. To support. Thus, the boss 7 to which the bolt 9 is attached functions as a restricting member that restricts the gap dimension D0 between the pump stand 4 and the base frame 6, in which the rubber vibration isolator 5 is sandwiched, to a set dimension or less.
ポンプ架台４の各脚部４２の側面、および、一方の短辺側面の中央部分には、取付け用ブラケット１０が固定されている。取付け用ブラケット１０の底板１０１の底面１０２は脚部４２の底面４３と同一高さ位置にある水平面である。この底面１０２と、この下側に位置するベースフレーム６のフレーム天板部分６１の天面６３との間に、円盤状の防振ゴム５が挟み込まれている。
A mounting bracket 10 is fixed to the side surface of each leg portion 42 of the pump base 4 and to the central portion of one short side surface. The bottom surface 102 of the bottom plate 101 of the mounting bracket 10 is a horizontal plane at the same height as the bottom surface 43 of the leg portion 42 . A disk-shaped rubber vibration isolator 5 is sandwiched between the bottom surface 102 and the top surface 63 of the frame top plate portion 61 of the base frame 6 positioned below.
防振ゴム５の上端面には同軸に上側ボルト軸部１２ａが取り付けられ、その下端面にも同軸に下側ボルト軸部１２ｂが取付けられている。上側ボルト軸部１２ａは、ポンプ架台４の側の取付け用ブラケット１０の底板１０１に形成した軸穴を貫通して上方に突出しており、突出した軸端部にはナット１３ａがねじ込まれて、底板１０１に固定されている。同様に、下側ボルト軸部１２ｂは、下側のベースフレーム６のフレーム天板部分６１に形成した軸穴を貫通して下方に突出しており、突出した軸部分にナット１３ｂがねじ込まれて、フレーム天板部分６１に固定されている。なお、本例では、防振ゴム５と上側の底板１０１との間に間隔調整用の円環状のスペーサ１４を挿入してある。このようにして、ポンプ架台４とベースフレーム６との間に、上下方向に弾性変形可能な状態で、防振ゴム５が挟み込まれている。
An upper bolt shaft portion 12a is coaxially attached to the upper end surface of the anti-vibration rubber 5, and a lower bolt shaft portion 12b is also attached coaxially to the lower end surface thereof. The upper bolt shaft portion 12a protrudes upward through a shaft hole formed in the bottom plate 101 of the mounting bracket 10 on the side of the pump base 4, and a nut 13a is screwed into the protruding shaft end portion to secure the bottom plate. 101 is fixed. Similarly, the lower bolt shaft portion 12b protrudes downward through a shaft hole formed in the frame top plate portion 61 of the lower base frame 6, and a nut 13b is screwed into the protruding shaft portion. It is fixed to the frame top plate portion 61 . In this example, an annular spacer 14 is inserted between the anti-vibration rubber 5 and the upper bottom plate 101 to adjust the gap. In this manner, the vibration isolator 5 is sandwiched between the pump mount 4 and the base frame 6 so as to be elastically deformable in the vertical direction.
ここで、ポンプ３が稼働していない状態において、防振ゴム５には、ポンプ３が搭載されたポンプ架台４の側から静荷重が加わり、弾性変形して所定量だけ押し潰された状態にある。この状態において、隣に位置しているボス７の下端部７２に取り付けたボルト９の頭部の上側の段差端面９２は、フレーム天板部分６１のフレーム裏面６４から一定の距離だけ下側に離れた非接触位置にある。このような位置関係となるように、ボス７の軸長、当該ボス７へのボルト９の取付け高さ等が設定されている。ボルト９の段差端面９２とフレーム裏面６４との間の距離Ｄ２は、ポンプ重量、防振ゴム５の弾性特性等によって適切に設定される。一方、ボス７は、ボス穴８に対して同軸に配置されており、先に述べたように、その外周面がボス穴８の内周縁８１に対して一定距離だけ離れた非接触状態にある。
Here, in a state where the pump 3 is not in operation, a static load is applied to the anti-vibration rubber 5 from the side of the pump base 4 on which the pump 3 is mounted, and it is elastically deformed and crushed by a predetermined amount. be. In this state, the upper stepped end surface 92 of the head of the bolt 9 attached to the lower end 72 of the adjacent boss 7 is separated downward from the frame rear surface 64 of the frame top plate portion 61 by a certain distance. in a non-contact position. The axial length of the boss 7, the mounting height of the bolt 9 to the boss 7, and the like are set so as to achieve such a positional relationship. A distance D2 between the stepped end surface 92 of the bolt 9 and the rear surface 64 of the frame is appropriately set according to the weight of the pump, the elastic characteristics of the rubber vibration isolator 5, and the like. On the other hand, the boss 7 is coaxially arranged with respect to the boss hole 8, and as described above, the outer peripheral surface thereof is in a non-contact state separated from the inner peripheral edge 81 of the boss hole 8 by a certain distance. .
なお、本例では、規制部材として機能するボス７は、ポンプ架台４およびベースフレーム６の間において４か所に配置されており、防振ゴム５は、これらの部材の間において５か所に配置されている。ボス７および防振ゴム５の配置箇所、個数は、載せるポンプ３の重量バランス等に応じて適宜設定され、本例の配置に限定されるものではない。
In this example, the bosses 7 functioning as regulating members are arranged at four locations between the pump mount 4 and the base frame 6, and the anti-vibration rubbers 5 are arranged at five locations between these members. are placed. The location and the number of bosses 7 and anti-vibration rubbers 5 are appropriately set according to the weight balance of the pump 3 to be mounted, and are not limited to the arrangement of this example.
このように構成されるポンプ支持機構２を備えたポンプ装置１は、図１に示すように、ポンプ３が搭載されたポンプ架台４が、防振ゴム５を挟み、ベースフレーム６に取り付けられている。この状態でポンプ装置１はポンプ設置場所等に輸送される。
As shown in FIG. 1, the pump device 1 having the pump support mechanism 2 configured as described above has a pump frame 4 on which the pump 3 is mounted, which is attached to the base frame 6 with anti-vibration rubber 5 interposed therebetween. there is In this state, the pump device 1 is transported to a pump installation site or the like.
輸送時にポンプ３の側に横揺れが発生した場合には、それに伴って、ポンプ３側のボス７が横に移動し、ベースフレーム６の側のボス穴８の内周縁８１に当接する。ボス７がベースフレーム６のボス穴８の内周縁８１に突き当たることで、ポンプ３側の過度な揺れが制限される。ベースフレーム６とポンプ架台４との間に挟み込まれている防振ゴム５には、ポンプ３側の横揺れに起因する過剰な力が作用することがなく、防振ゴム５が大きく変形することもない。よって、輸送時における過度な揺れを制限でき、また、過度な揺れに起因して防振ゴム５に破損、破断が生じることも回避できる。
When the pump 3 side shakes during transportation, the boss 7 on the pump 3 side moves laterally along with it and comes into contact with the inner peripheral edge 81 of the boss hole 8 on the base frame 6 side. Excessive swinging of the pump 3 is restricted by the boss 7 abutting against the inner peripheral edge 81 of the boss hole 8 of the base frame 6 . Excessive force caused by the lateral vibration of the pump 3 does not act on the vibration isolator 5 sandwiched between the base frame 6 and the pump stand 4, and the vibration isolator 5 is greatly deformed. Nor. Therefore, excessive shaking during transportation can be restricted, and damage or breakage of the anti-vibration rubber 5 due to excessive shaking can be avoided.
ポンプ設置場所などにおいてポンプ３を吊り上げる際には、ボス７に固定したボルト９が下側からベースフレーム６のフレーム裏面６４に当たり、それ以上、ポンプ架台４とベースフレーム６の間の上下方向の隙間寸法が広がることがない。これにより、防振ゴム５の伸びが制限され、防振ゴム５が過剰に変形して破損、破断することが回避される。また、ポンプ接続部材（配管、ベローズ）に過剰な負荷が加わることが防止されるので、ポンプ接続部材の破損を防止できる。さらに、ポンプ３が、装置ハウジング１Ａ、その他のポンプ周辺部材に接触することが防止されるので、接触に起因するポンプ３、周辺部材の損傷も防止できる。このように、ポンプ支持機構２では、ポンプ輸送時にポンプ３をベースフレーム６の側に固定するための固定ブラケット等の部品が不要となる。
When hoisting the pump 3 at a location where the pump is installed, the bolt 9 fixed to the boss 7 hits the frame rear surface 64 of the base frame 6 from below, and the vertical gap between the pump stand 4 and the base frame 6 is further increased. It never expands in size. As a result, the elongation of the vibration isolator 5 is restricted, and excessive deformation of the vibration isolator 5 to avoid damage or breakage is avoided. Moreover, since excessive load is prevented from being applied to the pump connecting member (pipe, bellows), damage to the pump connecting member can be prevented. Furthermore, since the pump 3 is prevented from coming into contact with the device housing 1A and other pump peripheral members, it is possible to prevent damage to the pump 3 and peripheral members due to contact. Thus, the pump support mechanism 2 does not require parts such as fixing brackets for fixing the pump 3 to the base frame 6 side during pump transportation.
ポンプ設置場所に設置されたポンプ３の運転時においては、ボス７に取り付けたボルト９（ストッパ）は、ベースフレーム６のフレーム裏面６４から下方に離れた位置にあり、フレーム裏面６４には接触しない。よって、防振ゴム５の弾性変形による振動騒音の抑制機能が阻害されることがない。
When the pump 3 installed at the pump installation location is in operation, the bolt 9 (stopper) attached to the boss 7 is positioned downwardly away from the frame rear surface 64 of the base frame 6 and does not come into contact with the frame rear surface 64. . Therefore, the function of suppressing vibration noise due to elastic deformation of the rubber vibration isolator 5 is not hindered.
