Description

【0001】
【発明の属する技術分野】
この発明は、例えば情報通信機器の空調に使用される空気調和装置または冷凍装置用振動防止装置、特に地震等の大きな揺れに対して空気調和装置または冷凍装置の筐体の変位を抑制することが出来る構造を備えた振動防止装置に関するものである。
【0002】
【従来の技術】
従来の空気調和装置または冷凍装置の筐体を支承する筐体支持部の振動防止装置は、複数の筐体支持部を防振材あるいは弾性体を介して架台上に設置すると共に、架台と防振材及び筐体支持部にボルトを貫通させ、ナット締めすることにより架台に固定していた。(例えば特許文献1参照)。

【発明が解決しようとする課題】
従来の空気調和装置または冷凍装置用振動防止装置は以上のように構成され、防振材が筐体支持部の下方に設置されていたため、装置全体としての高さは空気調和装置または冷凍装置の筐体の高さ寸法に防振装置の寸法が加算され、狭い室内では設置空間が確保しにくいという問題点があった。
また、空気調和装置または冷凍装置の圧縮機や送風機の振動がボルト及び架台を通して床面に伝達され、特に全速運転時においては振動が最大になるという問題点があった。更に、地震等の大きな揺れが発生した場合には、空気調和装置または冷凍装置の筐体が大きく変位するため、特に情報通信機器の空調に使用している空気調和装置においては、設置空間が狭く、空気調和装置の設置空間が限られていることもあって、筐体が周囲の機器に接触して破損させたり、高速で回転しているディスクなどに悪影響を及ぼす等の問題が生じる恐れがあった。
【0005】
地震の際の筐体の揺れ、あるいは大きな変位を抑制する手段としては、架台への筐体支持部の取付けを防振材や弾性体を介さずに直接架台に固定する方法があり、地震に対しては有効であるが、通常運転時に、筐体からの振動が架台や床面に伝達され、周囲の機器に振動による悪影響を及ぼす可能性がある。
この対策として、防振架台などを設置しようとすれば、十分な設置空間の確保が必要となり、狭い場所に設置した場合には作業効率が悪化するという問題点があった。また、筐体支持部の上部に防振材を設け、この防振材を強固に締め込むことも揺れの防止には有効であるが、締め込み量などの管理が必要となり、作業性が大幅に悪化するという問題点がある。
【0006】
この発明は、上述の各問題点に対処するためになされたもので、信頼性の高い防振固定構造を提供すると共に、地震に対して筐体の変位を抑制し、また、装置の高さ寸法に影響を与えることなく、電気的絶縁性の確保を図りつつ、外部への振動伝達を低減することができる空気調和装置または冷凍装置用振動防止装置を提供することを目的とする。
【0007】
【課題を解決するための手段】
この発明に係る空気調和装置または冷凍装置用振動防止装置は、空気調和装置または冷凍装置の筐体に設けられ、垂直足部と、この垂直足部の下端部から水平方向に延在しボルト孔が設けられた水平足部とを有する筐体支持部、この筐体支持部の上記水平足部を弾性材を介して支承する架台、この架台に固定され、上記弾性材及び上記水平足部のボルト孔を上記水平足部に非接触で貫通するボルト、上記ボルトに挿通され上記水平足部の上面に配設された防振材、この防振材の上面に配設されると共に、上記ボルトに挿通された平板部と、この平板部に連なって上記防振材の側面に位置し、上記水平足部との間に隙間を保持するようにされた側面部とを有する防振スペーサ及び上記防振スペーサの平板部の上部で上記ボルトに螺合され、上記平板部を介して上記防振材を上記水平足部に圧接するナットを備えたものである。
【0008】
【発明の実施の形態】
実施の形態1.
以下、この発明の実施の形態1を図にもとづいて説明する。図1は、実施の形態1による筐体支持部の固定構造を示す断面図である。この図において、空気調和装置または冷凍装置の筐体(図示せず)を支承する金属製の筐体支持部1は、垂直方向に延びる垂直足部1Aと、この垂直足部1Aの下端部を水平方向に折り曲げ、あるいは別の部材を固定することによって水平方向に延在するように形成された水平足部1Bとから構成され、架台2上に防振用の板状弾性体3を介して支承される。また、筐体支持部1の水平足部1Bにはボルト孔1Cが形成され、架台2に固定されたボルト4が架台2及び板状弾性体3並びにボルト孔1Cを貫通するように突設され、このボルト4に水平足部1Bの上方から円形の絶縁材からなる防振材5を挿通させて配設する。この防振材5は中心部の下端が上記ボルト孔1C内に嵌まり込むような小径部5Aとして形成され、筐体支持部1の水平足部1Bとボルト4との接触を防止するようにして、この部分での電気的な絶縁を確保している。
【0009】
また、防振材5は筐体支持部1が複数設けられる場合には、各筐体支持部が支承する重量に応じてそれぞれの筐体支持部の防振材の硬度が調整される。即ち、空気調和装置または冷凍装置の筐体内に配置される圧縮機や凝縮器等の機器の重量がそれぞれ異なるため、筐体を支承する各筐体支持部に加わる荷重も異なることになるが、各筐体支持部に設ける防振材5の硬度を同じにしておくと荷重に応じて筐体が傾くことになり、地震等の大きな揺れが発生した場合には周囲の機器に損傷を与え易くなるため、筐体の傾きを生じさせないようにするために防振材5の硬度を調整するものである。
【0010】
更に、防振材5の上方から、この発明の要部を構成する金属製の防振スペーサ6をボルト4に挿通する。この防振スペーサ6は、中央部の孔をボルト4に挿通し、防振材5の上面に配設される円形の平板部6Aと、この平板部6Aに連なって防振材5の側面に位置し、側面全体を覆うようにされた側面部6Bとから構成され、側面部6Bの下端は水平足部1Bとの間に所定の隙間を保持するようにされている。また、7はワッシャ8及び防振スペーサ6を介して防振材5を水平足部1Bに圧接するナットである。
なお、地震等の大きな揺れが発生した場合に、防振スペーサ6の側面部6Bと筐体支持部1の水平足部1Bあるいは垂直足部1Aとが接触するのを防止するため、水平足部1Bの上面の防振材5と接触する部分以外の部分及び垂直足部1Aの防振スペーサ側の面に絶縁用弾性体9を貼着して電気的な絶縁性を確保するようにしている。従って、防振スペーサ6の側面部6Bの下端と水平足部1Bとの隙間は、絶縁用弾性体9として比較的弾力性の小さいものが採用される場合は、側面部6Bの下端と絶縁用弾性体9の表面との間に所定の隙間を保持するようにし、絶縁用弾性体9が十分な弾力性を有する場合は、側面部6Bの下端と水平足部1Bとの間隔が所定値となるようにする。この場合は、側面部6Bの下端が絶縁用弾性体9の表面に接触するような状態になる場合もあり得る。
【0011】
上記の隙間は、また、空気調和装置または冷凍装置の筐体の高さ寸法に応じて適宜調整される。即ち、筐体の高さ寸法が大きい場合は、地震等の際、その上端の変位量(揺れ幅)が大きくなり、周囲の機器と接触し易くなるため、変位量を抑制する意味で隙間を小さくし、筐体の高さ寸法が小さい場合は、その上端の変位量も小さいため、隙間は比較的大きくすることができる。
また、防振スペーサ6の側面部6Bは、十分な強度が確保できる場合には、防振材5の側面全体を覆うような形とする必要はなく、平板部6Aの周縁部に適宜の数の突出部を形成し、これらの突出部を下方に折り曲げて形成するようにしてもよい。更に、防振スペーサ6の側面部6Bの下端は外側及び内側の角部に角取りのためのテーパ加工を施し、側面部6Bの下端が絶縁用弾性体9と接触した場合に、絶縁用弾性体9を損傷することがないようにしている。更にまた、側面部6Bの下端は地震等の際に絶縁用弾性体9または水平足部1Bに当接して筐体の変位量を規制するストッパとして機能するため、その機能に必要な面積を側面部下端にもたせる必要がある。
【0012】
実施の形態1は以上のように構成されているため、空気調和装置または冷凍装置の運転時に生ずる通常の振動は、架台2上の板状弾性体3及び防振材5によって吸収され、地震等の大きな揺れが発生した場合には、防振スペーサ6の側面部6Bの下端が絶縁用弾性体9あるいは水平足部1Bに当接し、ストッパとして機能するため、筐体の変位が所定量以下となるように抑制され、設置空間に制約を受ける情報通信機器の空調においても、筐体が揺れることによって周囲の機器に接触し、損傷させるような事態を防止することができる。
また、防振材5及び防振スペーサ6を筐体支持部の上部に配置し、架台上の装置の高さ寸法に影響を与えないようにしているため、筐体の変位量が抑制され、情報通信機器の空調では上記と同様な効果が期待できる。
なお、上記の構成において、防振スペーサ6を剛性の高い樹脂によって形成しても同様の効果を期待することができる。この場合には、筐体支持部との間の電気的な絶縁の必要性がなくなるため、絶縁用弾性体9が不要となる。
【0013】
実施の形態2.
次に、この発明の実施の形態2を図にもとづいて説明する。図2は、実施の形態2による筐体支持部の固定構造を示す断面図である。この図において、図1と同一または相当部分にはそれぞれ同一符号を付して説明を省略する。
図1と異なる点は、防振材5の側面に突出部5Bを設け、この突出部5Bを防振スペーサ6の側面部6Bの下端と筐体支持部1の水平足部1Bとの間に位置させて水平足部1Bの上面の絶縁用弾性体9の機能をもたせると共に、防振スペーサ6の上面及び外面を覆う第2の絶縁用弾性体10を設けた点である。
なお、突出部5Bの先端は、図示のように、防振スペーサ6の側面部6Bの外面まで延在するようにされ、側面部6Bの下端と水平足部1Bとの間隔は実施の形態1の隙間と同様に形成される。また、絶縁用弾性体9のうち垂直足部1Aの防振スペーサ側に貼着される部分は実施の形態1と同様に設けられる。
このような構成とすることにより、空気調和装置または冷凍装置の運転時における振動や地震等の揺れに対して実施の形態1と同様な効果が得られる他、防振スペーサ6と筐体支持部1との電気的な絶縁を容易に確実に得ることができる。
【0014】
実施の形態3.
次に、この発明の実施の形態3を図にもとづいて説明する。図3は、実施の形態3における防振スペーサの構成を示す平面図及び側断面図である。
防振スペーサ以外の構成は、実施の形態1または実施の形態2と同様であるため図示及び説明を省略する。図3(a)は、この実施の形態の第1実施例を示すもので、防振スペーサを楕円形の防振スペーサ61とし、平板部61Aと、その全周縁にわたって形成される側面部61Bとから構成している。平板部61Aの中央部に形成された孔61Cは図1あるいは図2のボルト4に挿入される孔である。また、図3(b)は、この実施の形態の第2実施例を示すもので、防振スペーサを長方形の防振スペーサ62とし、平板部62Aと、その全周縁にわたって形成される側面部62Bとから構成している。平板部62Aの中央部に形成された孔62Cはボルト4への挿通孔である。なお、(a)(b)いずれの場合も、側面部61Bあるいは62Bを平板部の全周縁にわたって形成する必要はなく、実施の形態1において説明したように、平板部61Aあるいは62Aの周縁部に適宜の数の突出部を形成し、これらの突出部を下方に折り曲げて形成するようにしてもよい。
このような構成とすることにより、実施の形態1あるいは2と同様な効果を期待することができる。
【0015】
【発明の効果】
この発明に係る空気調和装置または冷凍装置用振動防止装置は、空気調和装置または冷凍装置の筐体に設けられ、垂直足部と、この垂直足部の下端部から水平方向に延在しボルト孔が設けられた水平足部とを有する筐体支持部、この筐体支持部の上記水平足部を弾性材を介して支承する架台、この架台に固定され、上記弾性材及び上記水平足部のボルト孔を上記水平足部に非接触で貫通するボルト、上記ボルトに挿通され上記水平足部の上面に配設された防振材、この防振材の上面に配設されると共に、上記ボルトに挿通された平板部と、この平板部に連なって上記防振材の側面に位置し、上記水平足部との間に隙間を保持するようにされた側面部とを有する防振スペーサ及び上記防振スペーサの平板部の上部で上記ボルトに螺合され、上記平板部を介して上記防振材を上記水平足部に圧接するナットを備えたものであるため、空気調和装置または冷凍装置の運転時に生ずる通常の振動は、架台上の板状弾性体及び水平足部上の防振材によって吸収され、地震等の大きな揺れが発生した場合には、防振スペーサの側面部の下端が水平足部に当接し、ストッパとして機能するため、筐体の変位を所定量以下に抑制することができる。また、防振材及び防振スペーサを筐体支持部の水平足部の上部に配置しているため、架台上の装置の高さ寸法に影響を与えることがない。
従って、設置空間に制約を受ける場所での空調においても、筐体が揺れることによって周囲の機器に接触し、損傷させるような事態を防止することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention, for example, suppresses the displacement of a housing of an air conditioner or a refrigeration apparatus for a large vibration such as an earthquake, particularly for an air conditioner or a refrigeration apparatus used for air conditioning of information communication equipment. The present invention relates to a vibration prevention device having a structure that can be used.
[0002]
[Prior art]
BACKGROUND ART A conventional anti-vibration device for a housing supporting portion that supports a housing of an air conditioner or a refrigeration device is configured such that a plurality of housing supporting portions are installed on a gantry via a vibration isolator or an elastic body, and the gantry and the gantry are protected from vibration.

Japanese Utility Model Publication No. 7-20440 (paragraph 0010, FIG. 1)
[0004]
[Problems to be solved by the invention]
The conventional vibration control device for an air conditioner or a refrigeration device is configured as described above, and the vibration isolator is installed below the housing supporting portion. Therefore, the height of the entire device is equal to that of the air conditioner or the refrigeration device. There is a problem that the size of the vibration isolator is added to the height of the housing, and it is difficult to secure an installation space in a small room.
Further, there is a problem that vibrations of the compressor or the blower of the air conditioner or the refrigeration system are transmitted to the floor surface through the bolts and the gantry, and the vibrations are maximized particularly at the time of full speed operation. Furthermore, when a large shaking such as an earthquake occurs, the housing of the air conditioner or the refrigeration device is greatly displaced, so the installation space is narrow especially in the air conditioner used for air conditioning of information and communication equipment. Due to the limited space where the air conditioner can be installed, there is a risk that the housing may come into contact with surrounding equipment and cause damage, or may adversely affect disks rotating at high speed. there were.
[0005]
As a means of suppressing the shaking or large displacement of the housing during an earthquake, there is a method in which the mounting of the housing support unit to the mounting is directly fixed to the mounting without using vibration insulators or elastic bodies. However, during normal operation, the vibration from the housing is transmitted to the gantry or the floor surface, and there is a possibility that peripheral equipment may be adversely affected by the vibration.
As a countermeasure, there is a problem that a sufficient installation space needs to be secured if an anti-vibration gantry or the like is to be installed. In addition, it is effective to install a vibration isolator on the upper part of the housing support part and firmly tighten this anti-vibration material to prevent shaking. Is worse.
[0006]
The present invention has been made in order to address the above-described problems, and provides a highly reliable anti-vibration fixing structure, suppresses the displacement of a housing against an earthquake, and has a height of the device. An object of the present invention is to provide a vibration prevention device for an air conditioner or a refrigeration device that can reduce the transmission of vibration to the outside while ensuring electrical insulation without affecting dimensions.
[0007]
[Means for Solving the Problems]
An air conditioner or refrigeration apparatus vibration preventing device according to the present invention is provided on a housing of an air conditioner or a refrigeration device, and includes a vertical foot and a bolt hole extending horizontally from a lower end of the vertical foot. A housing supporting portion having a horizontal foot portion provided with a frame, a pedestal supporting the horizontal foot portion of the housing supporting portion via an elastic material, and being fixed to the pedestal, the elastic material and the horizontal foot portion A bolt penetrating the bolt hole in a non-contact manner with the horizontal foot, a vibration isolator inserted through the bolt and disposed on the upper surface of the horizontal foot, and a bolt disposed on the upper surface of the vibration isolator and the bolt A vibration-absorbing spacer having a flat plate portion inserted through the flat-plate portion and a side portion positioned on the side surface of the vibration-proof material connected to the flat-plate portion and configured to hold a gap between the horizontal foot portion and Screwed to the bolt at the top of the flat part of the vibration isolation spacer, The vibration-proof material through the plate portion is obtained with a nut which presses on the horizontal foot.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
Embodiment 1 FIG.
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view illustrating a fixing structure of a housing support unit according to the first embodiment. In this figure, a metal housing supporting portion 1 that supports a housing (not shown) of an air conditioner or a refrigeration system has a vertical foot 1A extending vertically and a lower end of the vertical foot 1A. And a horizontal foot 1B formed to extend in the horizontal direction by bending in the horizontal direction or by fixing another member, and is provided on the gantry 2 via a vibration-preventing plate-like elastic body 3. It is supported. Further, a bolt hole 1C is formed in the horizontal foot portion 1B of the housing support portion 1, and a bolt 4 fixed to the gantry 2 is provided so as to project through the gantry 2, the plate-like elastic body 3, and the bolt hole 1C. A vibration isolator 5 made of a circular insulating material is inserted through the bolt 4 from above the horizontal foot 1B. The anti-vibration member 5 is formed as a small-diameter portion 5A such that the lower end of the center portion fits into the bolt hole 1C so as to prevent the horizontal foot portion 1B of the housing support portion 1 from contacting the bolt 4. Therefore, electrical insulation is secured in this part.
[0009]
When a plurality of housing supports 1 are provided for the vibration insulator 5, the hardness of the vibration insulator of each housing support is adjusted in accordance with the weight supported by each housing support. That is, since the weights of the devices such as the compressor and the condenser arranged in the housing of the air conditioner or the refrigeration unit are different, the load applied to each housing supporting portion supporting the housing is also different, If the hardness of the vibration isolator 5 provided in each housing supporting portion is made the same, the housing will tilt according to the load, and if a large shaking such as an earthquake occurs, the surrounding devices are likely to be damaged. Therefore, the hardness of the vibration isolator 5 is adjusted to prevent the housing from tilting.
[0010]
Further, a metal vibration-isolating spacer 6, which is a main part of the present invention, is inserted into the bolt 4 from above the vibration-isolating material 5. The vibration-isolating spacer 6 is formed by inserting a hole in the center portion into the bolt 4 and forming a circular flat plate portion 6A provided on the upper surface of the vibration-isolating material 5 and a side surface of the vibration-isolating material 5 connected to the flat plate portion 6A. And a side surface portion 6B that covers the entire side surface, and a lower end of the side surface portion 6B is configured to hold a predetermined gap between itself and the horizontal foot portion 1B. Reference numeral 7 denotes a nut for pressing the vibration-proof material 5 to the horizontal foot 1B via the washer 8 and the vibration-proof spacer 6.
In addition, when a large shaking such as an earthquake occurs, the horizontal foot portion 1B or the vertical foot portion 1A of the housing supporting portion 1 is prevented from coming into contact with the horizontal foot portion 6B of the vibration isolation spacer 6 to prevent the contact. An insulating elastic body 9 is attached to a portion of the upper surface of 1B other than the portion in contact with the vibration isolating material 5 and to the surface of the vertical foot 1A on the vibration isolating spacer side to secure electrical insulation. . Therefore, the gap between the lower end of the side surface portion 6B of the vibration isolating spacer 6 and the horizontal foot portion 1B is set to the lower end of the side surface portion 6B when the elastic body 9 having relatively low elasticity is used. A predetermined gap is maintained between the elastic member 9 and the surface thereof, and when the insulating elastic member 9 has sufficient elasticity, the distance between the lower end of the side portion 6B and the horizontal foot portion 1B is equal to a predetermined value. To be. In this case, the lower end of the side portion 6B may come into contact with the surface of the insulating elastic body 9 in some cases.
[0011]
The gap is appropriately adjusted according to the height of the housing of the air conditioner or the refrigeration device. In other words, if the height of the housing is large, the amount of displacement (shake width) at the upper end of the case becomes large during an earthquake or the like, and it becomes easy to come into contact with surrounding devices. When the height is reduced and the height of the housing is small, the amount of displacement of the upper end is also small, so that the gap can be relatively large.
If sufficient strength can be ensured, the side surface portion 6B of the vibration isolating spacer 6 does not need to be formed so as to cover the entire side surface of the vibration isolating member 5, and an appropriate number of the peripheral portions of the flat plate portion 6A are provided. May be formed by bending these protrusions downward. Further, the lower end of the side surface portion 6B of the vibration isolating spacer 6 is subjected to a taper process for chamfering the outer and inner corners, and when the lower end of the side surface portion 6B comes into contact with the insulating elastic body 9, the insulating elastic member 9 is formed. The body 9 is not damaged. Furthermore, since the lower end of the side surface portion 6B functions as a stopper for restricting the amount of displacement of the housing by contacting the insulating elastic member 9 or the horizontal foot portion 1B in the event of an earthquake or the like, the area required for the function is reduced. It is necessary to put on the lower end.
[0012]
Since Embodiment 1 is configured as described above, normal vibrations generated during the operation of the air conditioner or the refrigeration system are absorbed by the plate-like elastic body 3 and the vibration-proof material 5 on the gantry 2, and an earthquake or the like occurs. When the large vibration occurs, the lower end of the side portion 6B of the vibration isolating spacer 6 contacts the insulating elastic body 9 or the horizontal foot portion 1B and functions as a stopper. Thus, even in air conditioning of information and communication equipment that is restricted by the installation space, it is possible to prevent a situation in which the housing is shaken to contact and damage surrounding equipment.
In addition, since the vibration isolating material 5 and the vibration isolating spacer 6 are arranged on the upper portion of the housing supporting portion so as not to affect the height of the device on the gantry, the displacement of the housing is suppressed, The same effects as above can be expected in air conditioning of information and communication equipment.
In the above configuration, the same effect can be expected even if the vibration isolation spacer 6 is formed of a resin having high rigidity. In this case, there is no need for electrical insulation between the housing supporting portion and the insulating elastic body 9 becomes unnecessary.
[0013]
Embodiment 2 FIG.
Next, a second embodiment of the present invention will be described with reference to the drawings. FIG. 2 is a cross-sectional view illustrating a fixing structure of a housing support unit according to the second embodiment. In this figure, the same or corresponding parts as those in FIG.
The difference from FIG. 1 is that a protrusion 5B is provided on the side surface of the vibration-proof material 5 and this protrusion 5B is provided between the lower end of the side surface portion 6B of the vibration-proof spacer 6 and the horizontal foot 1B of the housing support portion 1. The second embodiment is to provide a second insulating elastic body 10 that covers the upper surface and the outer surface of the vibration-isolating spacer 6 while having the function of the insulating elastic body 9 on the upper surface of the horizontal foot 1B.
The tip of the protruding portion 5B extends to the outer surface of the side surface portion 6B of the vibration isolating spacer 6 as shown in the figure, and the distance between the lower end of the side surface portion 6B and the horizontal foot portion 1B is the same as in the first embodiment. Is formed in the same manner as the gap. Further, a portion of the insulating elastic body 9 adhered to the vertical foot 1A on the side of the vibration isolating spacer is provided in the same manner as in the first embodiment.
By adopting such a configuration, the same effect as that of the first embodiment can be obtained with respect to vibration and vibration such as an earthquake during operation of the air conditioner or the refrigeration apparatus. 1 can be easily and reliably obtained.
