Description

Frame and air compression device including the same

本發明係關於收納產生壓縮空氣之空氣壓縮機構等之重物的框體及包含該框體之空氣壓縮裝置。The present invention relates to a housing for accommodating a heavy object such as an air compression mechanism that generates compressed air, and an air compressing device including the housing.

包含重物之框體，例如產生壓縮空氣之空氣壓縮裝置已於多種用途被利用。藉由搭載於車輛(例如鐵路車輛)之空氣壓縮裝置產生之壓縮空氣亦存在供給至使制動力作用於車輛之制動器裝置或使車輛門進行開閉動作之空壓機器之情況。專利文獻1提案搭載於鐵路車輛之空氣壓縮裝置。空氣壓縮裝置具有收納壓縮空氣之壓縮機構之框體。通常，空氣壓縮裝置係以框體懸吊於車輛下表面之方式安裝。 [先前技術文獻] [專利文獻] [專利文獻1]日本實用新型註冊第3150077號公報壓縮機構包含壓縮機及驅動該壓縮機之馬達，且保持於框體內。設計者對框體賦予可承受包含壓縮機及馬達等之重物之壓縮機構重量的構造。然而，若組裝框體之作業者之技術不夠，於框體之組裝時產生不週全，則亦有於懸吊在車輛下表面之框體之不週全部位產生過大應力的情形。過大之應力會加速框體所使用之金屬材料之疲勞。Frames containing heavy objects, such as air compression devices that generate compressed air, have been utilized in a variety of applications. The compressed air generated by the air compressing device mounted on a vehicle (for example, a railway vehicle) may be supplied to a pneumatic device that applies a braking force to the brake device of the vehicle or opens and closes the vehicle door. Patent Document 1 proposes to be mounted on an air compressor of a railway vehicle. The air compressing device has a housing for a compression mechanism that houses compressed air. Generally, the air compression device is mounted in such a manner that the frame is suspended from the lower surface of the vehicle. [Prior Art] [Patent Document 1] Japanese Laid-Open Patent Publication No. 3150077 The compression mechanism includes a compressor and a motor that drives the compressor, and is held in the casing. The designer gives the frame a structure that can withstand the weight of the compression mechanism including the weight of the compressor, the motor, and the like. However, if the skill of the operator who assembles the frame is insufficient, and the assembly of the frame is not satisfactory, there is a case where excessive stress is generated in all the positions of the frame suspended on the lower surface of the vehicle. Excessive stress accelerates the fatigue of the metal material used in the frame.

本發明之目的在於提供一種容易組裝，且不易產生起因於組裝不週全之過大應力的框體。本發明之一態樣之框體係形成供收納重物之內部空間之框體，且包含：支柱，其位於上述內部空間之形成角隅之2個側面之間；及支持板，其連接於上述支柱之上端部或下端部；上述支持板包含：板本體部；第1側片，其自上述板本體部延伸設置於上述支柱側，且重疊於上述2個側面中之一者；第2側片，其自上述板本體部延伸設置於上述支柱側，且重疊於上述2個側面中之另一者；及舌片，其於上述第1側片與上述第2側片之間自上述板本體部延伸設置於上述支柱側；且於上述第1側片、上述第2側片及上述舌片各者，形成與形成於上述支柱之複數個開口部分別重疊之連通孔。It is an object of the present invention to provide a frame body which is easy to assemble and which is less likely to cause excessive stress due to incomplete assembly. A frame system according to an aspect of the present invention forms a frame for accommodating an internal space of a weight, and includes: a pillar located between two sides forming a corner of the inner space; and a support plate connected to the above An upper end portion or a lower end portion of the pillar; the support plate includes: a plate body portion; and a first side plate extending from the plate body portion on the pillar side and overlapping one of the two side surfaces; the second side a sheet extending from the main plate body portion on the pillar side and superposed on the other of the two side surfaces; and a tongue piece between the first side panel and the second side panel from the panel The main body portion is extended on the pillar side; and each of the first side panel, the second side panel, and the tongue piece has a communication hole that overlaps each of the plurality of openings formed in the pillar.

＜第1實施形態＞於收納重物之框體中，藉由自彼此不同之複數個側面插入之複數根螺栓固定2個構件之情形，對於組裝工作不熟練的作業者有將螺栓自第1根開始擰緊之情形。藉此，因上述2個構件之相對位置係基於第1根螺栓而固定，故插入第2根以後之螺栓之2個構件之各孔部有未適當重疊之情形。不熟練之作業者若於其後將第2根螺栓強行插通至未適當重疊之2個孔部內，則會於該螺栓周圍產生過大應力。若如此以複數根螺栓緊固之組裝體支撐重物，則於強行插通之上述螺栓及螺栓周圍產生過大應力。該情形最終會加速2個構件之金屬疲勞。若組裝體適當組裝，則2個構件適當密接，於2個構件間獲得高摩擦力。高摩擦力有助於重物之支持，因而螺栓及螺栓周圍之應力被抑制為低程度。因此，若於2個構件間之適當相對位置下緊固複數根螺栓，則不會於組裝體內產生過大應力。本發明者等係開發了即便為不熟練之作業者，亦容易執行適當之組裝作業，且不易於螺栓周圍產生過大應力之框體之緊固構造。於第1實施形態中，說明例示框體之緊固構造。於第1實施形態中說明之框體之緊固構造可應用於鐵路車輛或其他移動體之車輛所搭載之多種空氣壓縮裝置。圖1係包含支柱SPT與頂板TPL之組裝體ASY之概略立體圖。圖2係圖1之橫剖視圖。參照圖1，說明組裝體ASY。支柱SPT包含第1板部FPP、第2板部SPP、及第3板部TPP。第1板部FPP、第2板部SPP及第3板部TPP係於垂直方向較長。第3板部TPP配置於第1板部FPP與第2板部SPP之間。第3板部TPP之寬度較第1板部FPP之寬度及第2板部SPP之寬度更窄。第1板部FPP與第2板部SPP於俯視時具有特定角度。第3板部TPP於俯視時，相對於第1板部FPP具有較第1板部FPP與第2板部SPP之上述特定角度更大之任意角度α(參照圖2)。又，第3板部TPP於俯視時，相對於第2板部SPP具有較第1板部FPP與第2板部SPP之上述特定角度更大之任意角度β(參照圖2)。第1板部FPP與第2板部SPP之上述特定角度、上述角度α及β之各外角之總和係設定為π。第3板部TPP、第1板部FPP或第2板部SPP之角度α、β可各自不同，但於本實施形態中設定成大致相同之角度(α＝β)。第1板部FPP、第2板部SPP及第3板部TPP係協動，形成角隅。於第1板部FPP之上端部，沿板厚方向形成第1開口部FON。於第2板部SPP之上端部，沿板厚方向形成第2開口部SON。於第3板部TPP之上端部，沿板厚方向形成第3開口部TON。第1開口部FON係為了納入延伸於第1方向A之第1緊固具而形成。第2開口部SON係為了納入延伸於與第1方向A不同之第2方向B之第2緊固具而形成。第3開口部TON係為了納入延伸於與第1方向A及第2方向B不同之第3方向C之第3緊固具而形成。第1緊固具、第2緊固具及第3緊固具各者亦可為螺栓、鉚釘、銷或可緊固支柱SPT與頂板TPL之其他棒狀零件。本實施形態之原理並未限定於作為第1緊固具、第2緊固具及第3緊固具被利用之特定零件。第1方向A、第2方向B及第3方向C與各開口部FON、SON、TON之軸線a1～a3方向一致。具體而言，該等軸線a1～a3之方向與第1～3板部FPP、SPP、TPP之法線(相對於平面之垂線)之方向一致或平行。各開口部FON、SON、TON之軸線a1～a3未必交叉於1點，但於未交叉於1點之情形，於使各軸線a1～a3中至少一條平行移動而於1點交叉之情形，第3開口部TON之軸線a3係位於第1開口部FON之軸線a1與第2開口部SON之軸線a2所成之角θ1(形成第1板部FPP、第2板部SPP及第3板部TPP之角隅側之角)之間。於本實施形態中，各開口部FON、SON、TON之各軸線a1～a3即使未平行移動亦於1點O交叉，且設定為第1開口部FON之軸線a1與第2開口部SON之軸線a2正交。又，第3開口部TON之軸線a3係設定為與第1開口部FON之軸線a1、與第2開口部SON之軸線a2所成之角θ1之二等分線一致。即，第3開口部TON之軸線a3與第1開口部FON之軸線a1所成之角中之角隅側之角θ2與第3開口部TON之軸線a3與第2開口部SON之軸線a2所成之角中之角隅側之角θ3相等。於第1緊固具、第2緊固具及第3緊固具各者若使用螺栓，則頂板TPL容易自支柱SPT卸除。因此，作業者可容易進行對由組裝體ASY包圍之機器之維護。頂板TPL包含頂面板部TSP、第1側片FSF、第2側片SSF、及舌片TGF。頂面板部TSP大致水平而橫置。第1側片FSF、第2側片SSF及舌片TGF各者與頂面板部TSP連續且彼此分離。第1側片FSF係藉由自頂面板部TSP彎折而自頂面板部TSP朝下方延伸，且與第1板部FPP之外表面重疊。第2側片SSF係藉由自頂面板部TSP彎折而自頂面板部TSP朝下方延伸，且與第2板部SPP之外表面重疊。舌片TGF係藉由自頂面板部TSP彎折而自頂面板部TSP朝下方延伸，且與第3板部TPP之外表面重疊。以舌片TGF重疊於第3板部TPP之外表面之狀態，第1及第2側片FSF、SSF分別同時重疊於第1及第2板部FPP、SPP。即，第1側片FSF、第2側片SSF、及舌片TGF之各法線與支柱SPT之第1板部FPP、第2板部SPP、及第3板部TPP之各法線一致(包含大致一致)。即，舌片TGF與頂面板部TSP之間之彎折線係自第1側片FSF與頂面板部TSP之間之彎折線彎曲。同樣，舌片TGF與頂面板部TSP之間之彎折線係自第2側片SSF與頂面板部TSP之間之彎折線彎曲。於本實施形態中，舌片TGF及頂面板部TSP之邊界所成之彎折線與第1側片FSF及頂面板部TSP之邊界所成之彎折線之間之夾角亦可與舌片TGF及頂面板部TSP之邊界所成之彎折線與第2側片SSF及頂面板部TSP之邊界所成之彎折線之間之夾角大致一致。於第1側片FSF之舌片TGF側之端部，沿厚度方向形成第1連通孔FCH。第1連通孔FCH與第1開口部FON重疊。於第2側片SSF之舌片TGF側之端部，沿厚度方向形成第2連通孔SCH。第2連通孔SCH與第2開口部SON重疊。於舌片TGF之中央部，沿厚度方向形成第3連通孔TCH。第3連通孔TCH與第3開口部TON重疊。該情形，第1連通孔FCH、第2連通孔SCH、第3連通孔TCH之軸線與第1開口部FON、第2開口部SON、第3開口部TON之軸線a1～a3一致或大致一致。因此，圖2中，關於該等各連通孔FCH～TCH之各軸線，亦以與圖2中各開口部FON、SON、TON之軸線a1～a3相同之軸線a1～a3表示。即，該等各連通孔FCH～TCH之軸線a1～a3係如圖2所示，根據各連通孔FCH～TCH之高度位置或水平位置未必交叉於1點，但於未交叉於1點之情形，使各軸線a1～a3平行移動而於1點交叉之情形，第3連通孔TCH之軸線a3位於第1連通孔FCH之軸線a1與第2連通孔SCH之軸線a2所成之角θ1(第1板部FPP、第2板部SPP及第3板部TPP形成之角隅側之角)之間。於本實施形態中，各連通孔FCH、SCH、TCH之各軸線a1～a3交叉於1點O，且設定為第1連通孔FCH之軸線a1與第2連通孔SCH之軸線a2正交。又，第3連通孔TCH之軸線a3設定為與第1連通孔FCH之軸線a1及第2連通孔SCH之軸線a2所成之角θ1之二等分線一致。即，第3連通孔TCH之軸線a3與第1連通孔FCH之軸線a1所成之角中之角隅側之角θ2與第3連通孔TCH之軸線a3及第2連通孔SCH之軸線a2所成之角中之角隅側之角θ3相等。作業者將頂板TPL載置於支柱SPT上。此時，第1側片FSF、第2側片SSF及舌片TGF亦可略微遠離支柱SPT。本實施形態之原理對施於頂板TPL之彎折加工未要求高精度。作業者首先將第3緊固具插通至第3連通孔TCH與第3開口部TON。作業者於其後若擰緊第3緊固具，則支柱SPT對於頂板TPL相對位移，第1開口部FON自動重疊於第1連通孔FCH(亦包含大致重疊之情形)。同樣，第2開口部SON自動重疊於第2連通孔SCH(亦包含大致重疊之情形)。舌片TGF及頂面板部TSP之邊界所成之彎折線與第1側片FSF及頂面板部TSP之邊界所成之彎折線之間之夾角若與舌片TGF及頂面板部TSP之邊界所成之彎折線與第2側片SSF及頂面板部TSP之邊界所成之彎折線之間之夾角大致一致，則第1開口部FON對於第1連通孔FCH之相對性位移及第2開口部SON對於第2連通孔SCH之相對性位移成為大致均等。然而，一般各連通孔FCH、SCH、TCH對於各開口部FON、SON、TON之相對位置多數考慮作業性或公差而未進行嚴密對位。因此，若以第1開口部FON及第1連通孔FCH為基準進行支柱SPT與頂板TPL之對位，則有支柱SPT相對於頂板TPL沿第1方向A偏向一側之情況。若產生該偏移，則有形成於與第1板部FPP正交之第2板部SPP之第2開口部SON、與形成於與第1側片FSF正交之第2側片SSF之第2連通孔SCH之間之位置偏移變大之情況。基於該位置偏移，有第2緊固具及該第2緊固具周圍之應力變高之情況。以第2開口部SON及第2連通孔SCH為基準，進行支柱SPT與頂板TPL之對位之情形亦同樣。該點，於本實施形態中，組裝體ASY包含支柱SPT、及連接於支柱SPT之上端部之頂板TPL，支柱SPT包含第1板部FPP及第2板部SPP、及俯視時對於第1板部FPP及第2板部SPP之各者具有較第1板部FPP與第2板部SPP之角度更大之角度之第3板部TPP，頂板TPL包含頂面板部TSP、自頂面板部TSP彎折並重疊於第1板部FPP之第1側片FSF、自頂面板部TSP彎折且重疊於第2板部SPP之第2側片SSF、及於第1側片FSF與第2側片SSF之間自頂面板部TSP彎折且重疊於第3板部TPP之舌片TSF，於第1側片FSF、第2側片SSF及上述舌片TSF各者，分別形成有與形成於支柱SPT之各開口部FON、SON、TON各者重疊之連通孔FCH、SCH、TCH，因而即便各開口部FON、SON、TON或各連通孔FCH、SCH、TCH基於公差等而未嚴密對位，於最初擰緊第3緊固具之情形，與最初擰緊第1或第2緊固具之情形相比，亦可減輕上述偏移。換言之，於本實施形態中，於上述構成之第1及第2板部FPP、SPP之間設置第3板部TPP，且於第1及第2側片FSF、SSF之間設置舌片TGF，第3板部TPP之第3開口部TON之軸線a3、或舌片TGF之第3連通孔TCH之軸線a3分別設定為與第1及第2板部FPP、SPP之各開口部FON、SON之軸線a1、a2之角度θ1、或第1及第2側片FSF、SSF之各連通孔FCH、SCH之軸線a1、a2之角度θ1之二等分線一致，因而即便未嚴密對位，亦如圖2中二點鏈線所示，於最初擰緊第3緊固具之情形，與最初擰緊第1或第2緊固具之情形相比，亦可減輕上述偏移，藉此第1開口部FON對於第1連通孔FCH之相對性位移、及第2開口部SON對於第2連通孔SCH之相對性位移係可設得較小且大致均等。因第1連通孔FCH與第1開口部FON之位置偏移較少，兩者重疊，故作業者隨後可將第1緊固具輕鬆地插入第1連通孔FCH與第1開口部FON。同樣，作業者可將第2緊固具輕鬆地插入第2連通孔SCH與第2開口部SON。作業者若遵守將第3緊固具先於其他緊固具緊固之組裝規則，則第1及第2緊固具、以及該等緊固具周圍之應力將被抑制於低程度，作業者可將頂板TPL安裝於支柱SPT而不對頂板TPL產生過大應力。若於第1緊固具、第2緊固具及第3緊固具各者使用螺栓，則第1側片FSF與第1板部FPP面接觸，且第2側片SSF與第2板部SPP面接觸。因此，於第1側片FSF與第1板部FPP之間及第2側片SSF及第2板部SPP之間產生強摩擦力。其結果，頂板TPL牢固地連接於支柱SPT。＜第2實施形態＞關於第1實施形態說明之構造可較佳地利用於多種空氣壓縮裝置。一般，空氣壓縮裝置係介隔頂板懸吊於鐵路車輛下表面。因此，配置於框體內部之壓縮機構之重量多數經由支柱施加於頂板。即，負荷集中施加於支柱與頂板之間之緊固部位(例如，壓縮機構之重量)。若對鐵路車輛組裝框體前，於頂板與支柱之組裝時於兩者間產生過大應力，則有超過設計空氣壓縮裝置之設計者所期望之頂板之耐荷重的負荷施加於頂板之虞。如關於第1實施形態之說明，具有舌片之頂板之構造因不易產生對頂板發生過大應力，故不易產生頂板或支柱破損。根據關於第1實施形態所說明之原理，作業者若遵守先對舌片進行緊固工作之作業順序，則與舌片協動形成角隅之2片金屬片(關於第1實施形態所說明之第1側片及第2側片)受到之荷重易均衡(對2片金屬片之一者施加過高負荷之風險降低)。於第2實施形態中，說明例示之空氣壓縮裝置。圖3A係第2實施形態之空氣壓縮裝置100之概略立體圖。圖3B係空氣壓縮裝置100之其他又一者之概略立體圖。參照圖1及圖3B，說明空氣壓縮裝置100。另，以下為方便起見，於各圖中記述X、Y、Z軸之情形時，將＋X方向作為右方向，＋Y方向作為前方向，＋Z方向作為上方向進行說明，但該等方向之表現並未特別限定，僅為表示本實施形態之相對位置關係者。空氣壓縮裝置100具備框體200、壓縮機構(未圖示)、冷卻機構300、除濕裝置400(參照圖3B)、及控制盤500(參照圖3B)。壓縮機構配置於由框體200形成之內部空間200A(參照圖5)。壓縮機構於框體200內壓縮空氣，產生壓縮空氣。其後將壓縮空氣供給至冷卻機構300。將壓縮空氣於冷卻機構300內冷卻。其後藉由除濕裝置400將壓縮空氣除濕。控制盤500控制壓縮機構及配置於框體200內之其他裝置。框體200包含頂板210(參照圖3A)、前側上罩體220、前側下罩體230、右面板240(參照圖3A)、左面板250(參照圖3B)、及底板260(參照圖3B)。頂板210與參照圖1說明之頂板TPL對應。因此，第1實施形態之說明亦可援用於頂板210。圖4係頂板210之概略立體圖。參照圖1至圖4，說明頂板210。如圖4所示，頂板210包含頂面板部211、前片212、後片213、右片214、左片215、及4個舌片216、217、218、219。頂面板部211係與後述之支柱610、620、630、640於俯視時之外緣對應之大致八角形。空氣壓縮裝置100安裝於鐵路車輛(未圖示)之下表面(未圖示)時，頂面板部211之上表面與鐵路車輛之下表面對向。頂面板部211與參照圖1說明之頂面板部TSP對應。因此，第1實施形態之說明亦可援用於頂面板部211。如圖4所示，前後左右之各片212～215係自頂面板部211朝下方彎折。前片212係用於前側上罩體220(參照圖3A)之安裝。後片213位於與前片212相反側。後片213係用於冷卻機構300(參照圖3B)之安裝。右片214位於右面板240(參照圖3A)之上方。左片215位於左面板250(參照圖3B)之上方。左片215位於右片214之相反側。前片212及後片213中一者與參照圖1說明之第1側片FSF對應。右片214及左片215中之一者係與參照圖1說明之第2側片SSF對應。因此，第1實施形態之說明亦可援用於前片212、後片213、右片214及左片215各者。如圖4所示，各舌片216、217、218、219自頂面板部211朝下方彎折。各舌片216、217、218、219分別位於前後左右之各片212～215中鄰接之各片212、213、214、215之間。該等之各舌片216、217、218、219與前後左右之各片212、213、214、215協動，形成框體200(參照圖3A)之各角隅。該等之各舌片216、217、218、219以與前後左右之各片212、213、214、215分離之狀態設置。藉此，可吸收後述之與框體600之組裝時之尺寸精度之偏差。圖5係支持頂板210(參照圖4)之框體600之概略立體圖。參照圖1至圖5，說明框體600。框體200(參照圖3A)包含框體600(參照圖5)。參照圖3說明之底板260係作為框體600之一部分而使用。如圖5所示，框體600除底板260外包含4個支柱610、620、630、640。支柱610、620、630、640各者係形成了形成框體200之大致長方體形狀之內部空間200A之角隅。藉由支柱610形成之角隅及藉由支柱640形成之角隅係排列於大致長方體形狀之內部空間200A之對角線上。藉由支柱620形成之角隅及藉由支柱630形成之角隅係排列於大致長方體形狀之內部空間200A之另1條對角線上。前側上罩體220(參照圖3A)及前側下罩體230(參照圖3A)封閉支柱610、620之間之空間。右面板240(參照圖3A)封閉支柱610、630之間之空間。左面板250(參照圖3B)封閉支柱620、640之間之空間。冷卻機構300、除濕裝置400及控制盤500係封閉支柱630、640之間之空間。如圖5所示，支柱610包含L字棒611及安裝片612。L字棒611自底板260朝上方延伸。L字棒611包含前板部613及右板部614。前側上罩體220(參照圖3A)及前側下罩體230(參照圖3A)抵接於前板部613。右面板240(參照圖3A)固定於右板部614。安裝片612嵌入形成於L字棒611之上緣之缺口部。安裝片612亦可較使用L字棒611之金屬材料更厚。安裝片612亦可熔接於L字棒611。安裝片612位於前板部613與右板部614之間。支柱610亦可與參照圖1說明之支柱SPT對應。前板部613亦可與參照圖1說明之第1板部FPP對應。右板部614亦可與參照圖1說明之第2板部SPP對應。安裝片612亦可與參照圖1說明之第3板部TPP對應。因此，第1實施形態之說明亦可援用於L字棒611及安裝片612。如圖5所示，於前板部613，2個螺栓孔615、616以沿左右方向排列之狀態形成。螺栓孔615、616形成於前板部613之上端部。於右板部614，2個螺栓孔617、618以沿前後方向排列之狀態形成。螺栓孔617、618形成於右板部614之上端部。於安裝片612形成螺栓孔619。螺栓孔615、616中一者亦可與參照圖1說明之第1開口部FON對應。螺栓孔617、618中一者亦可與參照圖1說明之第2開口部SON對應。螺栓孔619亦可與參照圖1說明之第3開口部TON對應。因此，第1實施形態之說明亦可援用於螺栓孔615、616、617、618、619。支柱620、630、640各者與支柱610於形狀及構造上相同。支柱610相關之說明被援用於支柱620、630、640各者。如圖4所示，於前片212，形成4個貫通孔651、652、653、654。貫通孔651、652之組形成於前片212之右端部，另一方面，貫通孔653、654之組形成於前片212之左端部。貫通孔651、652、653、654中一者亦可與參照圖1說明之第1連通孔FCH對應。因此，第1實施形態之說明亦可援用於貫通孔孔651、652、653、654各者。頂面板部211若重疊於支柱610、620、630、640(參照圖5)上，則貫通孔651重疊於支柱610之螺栓孔615(參照圖5)。貫通孔652重疊於支柱610之螺栓孔616(參照圖5)。貫通孔653重疊於支柱620之螺栓孔625(參照圖5)。貫通孔654重疊於支柱620之螺栓孔626(參照圖5)。將頂板210安裝於框體600之作業者可將螺栓B01(參照圖3A)插入貫通孔651，且螺合於螺栓孔615。其結果，前片212連接於支柱610、620。於本實施形態中，第1緊固具亦可藉由螺栓B01、B02、B03、B04中1者而例示。如圖4所示，於後片213，形成2個貫通孔655、656及3個螺栓孔657、658、659。貫通孔655形成於後片213之右端部，另一方面，貫通孔656形成於後片213之左端部。螺栓孔657、658、659於貫通孔655、656之間排成列。螺栓孔657、658、659係用於冷卻機構300(參照圖3B)之安裝。頂面板部211若重疊於支柱610、620、630、640(參照圖5)上，則貫通孔655重疊於支柱630之螺栓孔635(參照圖5)。此時，貫通孔656重疊於支柱640之螺栓孔645(參照圖5)。作業者可將螺栓(未圖示)插入貫通孔655，且螺合於螺栓孔635。作業者可將螺栓(未圖示)插入貫通孔656，且螺合於螺栓孔645。其結果，後片213連接於支柱630、640。如圖4所示，於右片214，形成4個貫通孔661、662、663、664。貫通孔661、662之組形成於右片214之前端部，另一方面，貫通孔663、664之組形成於右片214之後端部。貫通孔661、662、663、664中一者亦可與參照圖1說明之第2連通孔SCH對應。因此，第1實施形態之說明亦可援用於貫通孔661、662、663、664各者。頂面板部211若重疊於支柱610、620、630、640(參照圖5)上，則貫通孔661重疊於支柱610之螺栓孔617(參照圖5)。貫通孔662重疊於支柱610之螺栓孔618(參照圖5)。貫通孔663重疊於支柱630之螺栓孔637(參照圖5)。貫通孔664重疊於支柱630之螺栓孔638(參照圖5)。將頂板210安裝於框體600之作業者可將螺栓B05(參照圖3A)插入貫通孔661，且螺合於螺栓孔617。作業者可將螺栓B06(參照圖3A)插入貫通孔662，且螺合於螺栓孔618。作業者可將螺栓B07(參照圖3A)插入貫通孔663，且螺合於螺栓孔637。作業者可將螺栓B08(參照圖3A)插入貫通孔664，且螺合於螺栓孔638。其結果，右片214連接於支柱610、630。於本實施形態中，第2緊固具亦可藉由螺栓B05、B06、B07、B08中1者而例示。如圖4所示，於左片215，形成4個貫通孔665、666、667、668。貫通孔665、666之組形成於左片215之前端部，另一方面，貫通孔667、668之組形成於左片215之後端部。貫通孔665、666、667、668中一者亦可與參照圖1說明之第2連通孔SCH對應。因此，第1實施形態之說明亦可援用於貫通孔孔665、666、667、668各者。頂面板部211若重疊於支柱610、620、630、640(參照圖5)上，則貫通孔665重疊於支柱620之螺栓孔627(參照圖5)。貫通孔666重疊於支柱620之螺栓孔628(參照圖5)。貫通孔667重疊於支柱640之螺栓孔647(參照圖5)。貫通孔668重疊於支柱640之螺栓孔648(參照圖5)。將頂板210安裝於框體600之作業者可將螺栓B09(參照圖3B)插入貫通孔665，且螺合於螺栓孔627。作業者可將螺栓B10(參照圖3B)插入貫通孔666，且螺合於螺栓孔628。作業者可將螺栓B11(參照圖3B)插入貫通孔667，且螺合於螺栓孔647。作業者可將螺栓B12(參照圖3B)插入貫通孔668，且螺合於螺栓孔648。其結果，左片215連接於支柱620、640。於本實施形態中，第2緊固具亦可藉由螺栓B09、B10、B11、B12中1者而例示。於舌片216(參照圖4)形成貫通孔(未圖示)。於舌片217(參照圖4)形成貫通孔671(參照圖4)。於舌片218(參照圖4)形成貫通孔672(參照圖4)。於舌片219(參照圖4)形成貫通孔(未圖示)。頂面板部211若重疊於支柱610、620、630、640(參照圖5)上，則舌片216之貫通孔(未圖示)重疊於形成於支柱610之安裝片612(參照圖5)之螺栓孔619(參照圖5)。舌片217之貫通孔671重疊於形成於支柱620之安裝片622(參照圖5)上之螺栓孔(未圖示)。舌片218之貫通孔672重疊於支柱630之安裝片632(參照圖5)之螺栓孔639(參照圖5)。舌片219之貫通孔(未圖示)重疊於支柱640之安裝片642(參照圖5)之螺栓孔649。將頂板210安裝於框體600之作業者可將螺栓B13(參照圖3A)插通於舌片216之貫通孔(未圖示)，且螺合於形成於支柱610之安裝片612上之螺栓孔619。其結果，舌片216緊固於安裝片612。作業者可將螺栓B14(參照圖3A)插通於舌片217之貫通孔671，且螺合於形成於支柱620之安裝片622上之螺栓孔(未圖示)。其結果，舌片217緊固於安裝片622。作業者可將螺栓B15(參照圖3A)插通於舌片218之貫通孔672，且螺合於形成於支柱630之安裝片632上之螺栓孔639。其結果，舌片218緊固於安裝片632。作業者可將螺栓B16(參照圖3B)插通於舌片219之貫通孔(未圖示)，且螺合於支柱640之安裝片642之螺栓孔649。其結果，舌片219緊固於安裝片642。根據關於第1實施形態說明之組裝原理，作業者首先將舌片216、217、218、219分別緊固於支柱610、620、630、640之安裝片612、622、632、642。其結果，與將前後左右之各片212、213、214、215首先分別緊固於支柱610、620、630、640之情形相比，可抑制頂板210對於各支柱610、620、630、640之前後左右之偏移，作業者可適當調整頂板210(參照圖4)與框體600(參照圖5)之間之相對位置關係。其後，作業者可將前片212、後片213、右片214及左片215緊固於支柱610、620、630、640，且將頂板210固定於框體600。於本實施形態中，參照圖1說明之第3緊固具亦可與螺栓B13、B14、B15、B16中1者對應。＜第3實施形態＞一般，空氣壓縮裝置因自鐵路車輛之下表面懸吊，故設計者亦可對連接於鐵路車輛下表面之框體之頂板賦予多種補強構造。於第3實施形態中，說明例示補強構造。如圖4所示，頂板210包含2條橫肋710、720、及2條縱肋730、740。橫肋710、720及縱肋730、740係形成格柵狀之補強構造。頂板210係藉由格柵狀之補強構造而構造性地被強化。橫肋710、720與前片212及後片213並排，於右片214與左片215之間延伸。於本實施形態中，第1補強肋藉由橫肋710、720中之1者例示。縱肋730、740係與右片214及左片215並排，於前片212與後片213之間延伸。縱肋730、740係於右片214與左片215之間，自頂面板部211朝下方突出。於本實施形態中，第2補強肋部藉由縱肋730、740中之1者例示。由橫肋710、720與縱肋730、740形成之格柵狀之補強構造係將頂面板部211之區域分割成9個區域A01～A09。區域A01由前片212、右片214、舌片216、橫肋710及縱肋730包圍。區域A02由前片212、左片215、舌片217、橫肋710及縱肋740包圍。區域A03由後片213、右片214、舌片218、橫肋720及縱肋730包圍。區域A04由後片213、左片215、舌片219、橫肋720及縱肋740包圍。區域A05由前片212、橫肋710及縱肋730、740包圍。區域A06藉由右片214、橫肋710、720及縱肋730包圍。區域A07由左片215、橫肋710、720及縱肋740包圍。區域A08由後片213、橫肋720及縱肋730、740包圍。區域A09由橫肋710、720及縱肋730、740包圍。區域A01～A04之形狀及大小彼此大致一致。區域A01～A04各者係較其他區域A05～A09各者小。區域A01～A04各者中設有形成為圓盤狀之安裝部761～764。各安裝部761～764形成有安裝孔751～754。該安裝部761～764具有減振構造，可抑制自框體200朝鐵路車輛(未圖示)之振動傳遞。圖3A顯示2個安裝構件ATM。安裝構件ATM係為了於鐵路車輛(未圖示)之下表面(未圖示)懸吊框體200而使用。於本實施形態中，懸吊構造體藉由安裝構件ATM而例示。如圖3A所示，安裝構件ATM載置於頂面板部211上。安裝構件ATM藉由插通於安裝孔751、752、753、754之螺栓構件，而固定於頂面板部211上。本實施形態之空氣壓縮裝置100因藉由橫縱肋710、720、730、740構造性地強化了頂板210，故可抑制頂板210之變形。尤其，空氣壓縮裝置100因設有安裝孔751～754之區域A01～A04形成為較小，故可於鐵路車輛(未圖示)之下表面牢固地安裝框體200。另，於本實施形態中，橫縱肋710、720、730、740各設置有2條，但條數並未限定於此。＜第4實施形態＞關於第3實施形態說明之補強構造亦可藉由將細長金屬板片熔接於頂面板部而形成。然而，遍及過長距離之熔接要求較高之熔接技能。於第4實施形態中，說明補強構造之簡單作成技術。圖6係利用於頂板210之製造之板構件之概略立體圖。參照圖3A、圖4及圖6，說明頂板210。如圖6所示，頂板210由矩形狀之第1板材760及矩形狀之第2板材770形成。第2板材770佔據參照圖4說明之區域A09。第1板材760形成其他區域A01～A08。圖7係第1板材760之概略俯視圖。參照圖4、圖6及圖7，說明對於第1板材760之加工。圖7中之實線表示切斷線或外形線。圖7中之虛線意指彎折線。對於圖6所示之矩形狀之第1板材760施以沖孔加工，形成圖7所示之形狀。圖7係顯示表示形成於第1板材760之外緣之大致三角形狀之複數個切入部之頂點的點P01～點P08。於點P01與點P02之間延伸之虛線D01(參照圖7)表示頂面板部211與前片212之間之邊界。虛線D01相對於螺栓B05、B06、B07、B08(參照圖3A)之插入方向大致平行。前片212沿虛線D01朝下方彎折。於點P05與點P06之間延伸之虛線D02(參照圖7)表示頂面板部211與後片213之間之邊界。虛線D02相對於螺栓B05、B06、B07、B08(參照圖3A)之插入方向大致平行。後片213沿虛線D02朝下方彎折。於本實施形態中，第1外彎折線係由虛線D01、D02中一者例示。於點P07與點P08之間延伸之虛線D03(參照圖7)表示頂面板部211與右片214之間之邊界。虛線D03相對於螺栓B01、B02、B03、B04(參照圖3A)之插入方向大致平行。右片214沿虛線D03朝下方彎折。於點P03與點P04之間延伸之虛線D04(參照圖7)表示頂面板部211與左片215之間之邊界。虛線D04相對於螺栓B01、B02、B03、B04(參照圖3A)之插入方向大致平行。左片215沿虛線D04朝下方彎折。於本實施形態中，第2彎折線係由虛線D03、D04中一者而例示。於點P01與點P08之間延伸之虛線D05表示頂面板部211與舌片216之邊界。舌片216沿虛線D05朝下方彎折。於點P02與點P03之間延伸之虛線D06表示頂面板部211與舌片217之邊界。舌片217沿虛線D06朝下方彎折。於點P06與點P07之間延伸之虛線D07表示頂面板部211與舌片218之邊界。舌片218沿虛線D07朝下方彎折。於點P04與點P05之間延伸之虛線D08表示頂面板部211與舌片219之邊界。舌片219沿虛線D08朝下方彎折。圖7顯示點P09～點P12。點P09～點P12相當於形成於頂面板部211內之矩形區域之頂點。圖7係於點P09與點P10之間，顯示點P13與點P14。點P09、點P10、點P13及點P14排列於1條直線上。點P09、點P10、點P13及點P14排成列之直線相對於虛線D01大致平行。點P13位於點P09與點P14之間。點P14位於點P10與點P13之間。圖7係於點P11與點P12之間，顯示點P15與點P16。點P11、點P12、點P15及點P16係排列於1條直線上。點P11、點P12、點P15及點P16排成列之直線相對於虛線D02大致平行。點P15位於點P11與點P16之間。點P16位於點P12與點P15之間。藉由上述之沖孔加工，於點P09與點P13之間形成切入線C01。於點P10與點P14之間形成切入線C02。於點P11與點P15之間形成切入線C03。於點P12與點P16之間形成切入線C04。圖7顯示點P17～點P20。點P17～點P20相當於藉由點P09～點P12形成之矩形區域內描繪之矩形區域之頂點。點P13、點P16、點P17及點P20係排列於1條直線上。藉由上述之沖孔步驟，形成沿點P13、點P16、點P17及點P20排成列之直線之切入線C05。切入線C05相對於虛線D03大致平行。點P14、點P15、點P18及點P19係排列於1條直線上。藉由上述之沖孔步驟，形成沿點P14、點P15、點P18及點P19排成列之直線之切入線C06。切入線C06相對於虛線D04大致平行。藉由上述之沖孔加工，形成於點P17與點P18之間延伸之切入線C07。切入線C07相對於虛線D01大致平行。藉由上述之沖孔加工，形成於點P19與點P20之間延伸之切入線C08。切入線C08相對於虛線D02大致平行。如圖4所示，橫肋710包含中央肋711、右延長肋712、及左延長肋713。於圖7顯示虛線D09。虛線D09表示頂面板部211與中央肋711之邊界。虛線D09相對於虛線D01大致平行。中央肋711沿虛線D09朝下方彎折。如圖4所示之右延長肋712係於中央肋711之右端至右片214之區間中，熔接於頂面板部211。如圖4所示之左延長肋713係於中央肋711之左端至左片215之區間中，熔接於頂面板部211。中央肋711係藉由彎折加工而形成，因而可簡便地形成橫肋710，而不需要過長之熔接區間。如圖4所示，橫肋720包含中央肋721、右延長肋722及左延長肋723。於圖7顯示虛線D10。虛線D10表示頂面板部211與中央肋721之邊界。虛線D10相對於虛線D02大致平行。中央肋721沿虛線D10朝下方彎折。圖4所示之右延長肋722係於中央肋721之右端至右片214之區間中，熔接於頂面板部211。圖4所示之左延長肋723係於中央肋721之左端至左片215之區間中，熔接於頂面板部211。中央肋721係藉由彎折加工而形成，因而可簡便地形成橫肋720係，而不需要過長之熔接區間。如圖4所示，縱肋730包含中央肋731、前延長肋732、及後延長肋733。於圖7顯示虛線D11。虛線D11表示頂面板部211與中央肋731之邊界。虛線D11相對於虛線D03大致平行。中央肋731沿虛線D11朝下方彎折。圖4所示之前延長肋732與橫肋710與前片212大致正交，且與中央肋731排成列。前延長肋732熔接於頂面板部211。圖4所示之後延長肋733與橫肋720與後片213大致正交，且與中央肋731排成列。後延長肋733熔接於頂面板部211。中央肋731藉由彎折加工而形成，因而可簡便地形成縱肋730，而不需要過長之熔接區間。如圖4所示，縱肋740包含中央肋741、前延長肋742及後延長肋743。於圖7顯示虛線D12。虛線D12表示頂面板部211與中央肋741之邊界。虛線D12相對於虛線D04大致平行。中央肋741沿虛線D12朝下方彎折。圖4所示之前延長肋742與橫肋710及前片212大致正交，且與中央肋741排成列。前延長肋742熔接於頂面板部211。圖4所示之後延長肋743與橫肋720及後片213大致正交，且與中央肋741排成列。後延長肋743熔接於頂面板部211。中央肋741藉由彎折加工而形成，因而可簡便地形成縱肋740，而不需要過長之熔接區間。於本實施形態中，第1彎折肋藉由中央肋711、721中1者而例示。第2彎折肋藉由中央肋731、741中1者而例示。第1延長肋藉由右延長肋712、722及左延長肋713、723中1者而例示。第2延長肋藉由前延長肋732、742及後延長肋733、743中1者而例示。第1內彎折線藉由虛線D09、D10中1者而例示。第2內彎折線藉由虛線D11、D12中1者而例示。中央肋711、721、731、741之彎折加工之結果，藉由點P09、點P10、點P11及點P12形成之矩形區域(具有沿虛線D09～D12及切入線C01～C04之輪廓線之區域)開口。第2板材770封閉所開口之矩形區域。第2板材770亦可熔接於頂面板部211。於本實施形態中，蓋板由第2板材770例示。本實施形態之頂板210係橫縱肋710、720、730、740包含彎折了第1板材760之中央肋711、721、731、741、及藉由熔接而附接於第1板材760之各延長肋712、722、713、723、732、742、733、743而構成，因而可縮短利用肋構築補強構造時之熔接區間，藉此可簡便地形成補強構造。＜第5實施形態＞配置於框體內之壓縮機構亦可使用多種已知之裝置而形成。壓縮機構亦可包含渦卷式壓縮機、旋轉式壓縮機、擺動式壓縮機及往復動式壓縮機中的1者。於第5實施形態中，說明例示壓縮機構。圖8係由框體600支持之壓縮機構800之概略立體圖。參照圖3A、圖7及圖8，說明壓縮機構800。壓縮機構800包含渦卷式壓縮機810及馬達820。馬達820係於參照圖3A說明之控制盤500之控制下，產生驅動力。驅動力係藉由使用皮帶或滑輪之一般零件構築之傳遞機構(未圖示)，自馬達820向渦卷式壓縮機810傳遞。驅動力產生渦卷式壓縮機810之搖動旋轉。其結果，渦卷式壓縮機810可壓縮空氣，產生壓縮空氣。框體600包含2條樑材681、682。樑材681於支柱610、620之間大致水平延伸。樑材682於支柱630、640之間大致水平延伸。樑材681位於頂面板部211(參照圖7)與前片212(參照圖7)之間之彎折線(圖7所示之虛線D01)之下方。樑材682位於頂面板部211與後片213(參照圖7)之間之彎折線(圖7所示之虛線D02)之下方。框體600進而包含支持板690。支持板690包含主板部691、及4個耳部692。圖8係顯示4個耳部692中的3個。4個耳部692中的2個自支持板690朝前方突出，且連接於樑材681。4個耳部692中的另外2個係自支持板690朝後方突出，且連接於樑材682。渦卷式壓縮機810安裝於主板部691之上表面。馬達820安裝於主板部691之下表面。渦卷式壓縮機810及馬達820係排列於垂直方向，因而設計者亦可不對框體600之水平方向之剖面堤賦予較大值。＜第6實施形態＞壓縮機構產生壓縮空氣之期間，壓縮機構產生振動。本發明人等開發了降低自壓縮機構向鐵路車輛傳遞之振動的技術。於第6實施形態中，說明例示振動降低技術。圖9係耳部692周圍之框體200之概略剖視圖。參照圖8及圖9，說明耳部692周圍之框體200構造。如圖9所示，框體200包含防振環910、防振襯套920、螺栓930、墊圈940、2個螺母951、952。防振環910由樑材683與耳部692夾著。樑材683與參照圖8說明之樑材681、682分別對應。耳部692藉由防振環910與樑材683朝上方隔開。因此，壓縮機構800之振動未自支持板690(參照圖8)向樑材683直接傳遞。於本實施形態中，防振材由防振環910例示。防振襯套920配置於樑材683上。因此，樑材683由防振環910與防振襯套920夾著。螺栓930包含頭部931、主體部932及螺絲部933。螺母951、952係緊固於螺絲部933。頭部931熔接於樑材683之下表面。主體部932係自頭部931朝上方突出，且貫通樑材683、防振環910、防振襯套920。主體部932包含連接於頭部931之下部935、及自下部935朝上方延伸之上部936。於樑材683形成有供主體部932插入之貫通孔684。貫通孔684之直徑較主體部932之下部935之直徑更大。因此，樑材683不易接觸螺栓930。其結果，不易產生自螺栓930朝樑材683之振動傳遞。防振環910之內徑與主體部932之下部935之直徑大致相等。防振環910未與主體部932之上部936接觸，因而自防振環910朝螺栓930之振動傳遞量僅少許。於本實施形態中，緊固棒由螺栓930例示。接觸部由頭部931例示。貫通部由主體部932、自主體部932朝上方延伸之螺絲部933例示。耳部692包含規定供主體部932插入之貫通孔693之緣部694。貫通孔693之直徑較主體部932之直徑更大。因此，緣部694不易接觸螺栓930。其結果，不易產生自耳部692朝螺栓930之振動傳遞。防振襯套920包含下環部921及上環部922。上環部922之內徑與下環部921之內徑一致，另一方面，上環部922之外徑大於下環部921之外徑。下環部921自上環部922朝下方突出，填充耳部692之緣部694與螺栓930之主體部932之間之細環狀空間。其結果，耳部692對於螺栓930適當定位。螺絲部933之外徑小於主體部932之直徑。因此，於主體部932與螺絲部933之邊界形成階部934。於本實施形態中，第1棒部由主體部932例示。第2棒部由螺絲部933例示。墊圈940包含圍住螺栓930之主體部932前端之下部941、及圍住螺栓930之螺絲部933基端之上部942。墊圈940之下部941之內徑係小於主體部932之直徑，因而墊圈940之高度位置由階部934之位置決定。如圖9所示，於墊圈940之下表面與防振襯套920之上表面之間，形成薄空隙。其結果，不易產生自防振襯套920朝墊圈940之振動傳遞。設計者可根據與上述多種實施形態相關說明之設計原理，設計多種空氣壓縮裝置。亦可將與上述多種實施形態中之一者相關說明之多種特徵中之一部分應用於與其他又一者之實施形態相關說明之空氣壓縮裝置。＜其他實施形態＞於上述第1實施形態中，對連接於支柱SPT之「支持板」，作為連接於支柱SPT之上端部之「頂板」加以說明，但該「支持板」亦可作為連接於支柱SPT之下端部之「底板」而構成。該情形，底板具有如將頂板TPL之上下反轉之構成，具體而言包含底面板部、第1側片、第2側片及舌片。此種底板，於重物設置於底板上之情形，於該底板與支柱之間，與頂板與支柱同樣，亦可能引起應力集中於底板與支柱之緊固部位。即，與形成於支柱SPT之各開口部各者重疊之連通孔分別形成於底板，因而各開口部或各連通孔基於公差等，即使未進行嚴密對位，於最初擰緊第3緊固具之情形，與最初擰緊第1或第2緊固具之情形相比，仍可減輕偏移。又，於上述第1實施形態中，舌片TGF與第1側片FSF或第2側片SSF彼此分斷，但該等各片TGF、FSF、SSF亦可為彼此連接者。該情形，舌片TGF與第1側片FSF之連接部分、或舌片TGF與第2側片SSF之連接部分亦可作為角部構成，或可作為彎折連接部分構成者。再者，於上述第2實施形態等中，於框體200之內部空間200A收納空氣壓縮機構，但收納於該內部空間200A之重物並未限定於空氣壓縮機構。例如，亦可為於該框體200之內部空間200A，收納電動馬達等之驅動機器、減速機或離合器等之傳動機器、泵或發電機等之作動機器、電池等之重物者。

此處，對上述實施形態進行概述。本發明之一態樣之框體係形成供收納重物之內部空間。上述框體包含：支柱，其位於形成上述內部空間之角隅之2個側面之間；及支持板，其連接於上述支柱之上端部或下端部；上述支持板包含：板本體部；第1側片，其自上述板本體部延伸設置於上述支柱側，且與上述2個側面中的一者重疊；第2側片，其自上述板本體部延伸設置於上述支柱側，且與上述2個側面中的另一者重疊；及舌片，其於上述第1側片與上述第2側片之間自上述板本體部延伸設置於上述支柱側；且於上述第1側片、上述第2側片及上述舌片各者，形成有與形成於上述支柱之複數個開口部分別重疊之連通孔。根據上述構成，於支柱之上端部連接頂板之作業者可將形成於舌片之連通孔與形成於支柱之複數個開口部中的1個重疊。其結果，作業者可將緊固具插通於舌片之連通孔及對應之開口部。如此，第1側片與上述第2側片之間之舌片對於支柱而定位，藉此第1側片及第2側片各者對於支柱之相對位置被適當決定。若第1側片及第2側片對於支柱適當定位，則第1側片及第2側片各者之連通孔與形成於支柱之對應開口部重疊。因此，作業者可將緊固具輕鬆地插通於第1側片及第2側片各者之連通孔及對應之開口部。其結果，作業者可不產生不週全地組裝框體，且於用以將第1側片及第2側片分別安裝於支柱之緊固具周圍不易產生過大應力。關於上述構成，使上述第1側片之連通孔、第2側片之連通孔及上述第3側片之連通孔之各軸線之交點一致之情形，上述第3側片之連通孔之軸線亦可位於上述第1側片之連通孔之軸線與第2側片之連通孔之軸線所成之角，即上述角隅側之角之間。該情形，「使上述第1側片之連通孔、第2側片之連通孔及上述第3側片之連通孔之各軸線之交點一致之情形」係於各連通孔之軸線一致之情形係指該狀態，且於該等之各軸線未交叉於1點之情形，係指至少使任一條軸線平行移動且交叉於1點之情形之狀態。該情形，上述第3側片之連通孔之軸線亦可與上述角隅側之角之二等分線一致。根據上述構成，可將各連通孔適當形成於各片。關於上述構成，上述支柱亦可包含與上述第1側片重疊之第1板部、與上述第2側片重疊之第2板部、及於上述第1板部與上述第2板部之間重疊於上述舌片之第3板部。上述複數個開口部亦可包含形成於上述第1板部之第1開口部、形成於上述第2板部之第2開口部、及形成於上述第3板部之第3開口部。於上述第1側片，亦可形成與上述第1開口部重疊之第1連通孔作為上述連通孔。於上述第2側片，亦可形成與上述第2開口部重疊之第2連通孔作為上述連通孔。於上述舌片，亦可形成與上述第3開口部重疊之第3連通孔作為上述連通孔。根據上述構成，作業者可將緊固具插通於第3連通孔及第3開口部。緊固具對第3連通孔及第3開口部插通之結果，第1側片對於支柱之相對位置係被適當決定，因而第1連通孔與第1開口部重疊。因此，作業者可將另1個緊固具輕鬆地插通於第1連通孔及第1開口部。緊固具對第3連通孔及第3開口部插通之結果，第2側片對於支柱之相對位置亦被適當決定，因而第2連通孔與第2開口部重疊。因此，作業者可將另1個緊固具輕鬆地插通於第2連通孔及第2開口部。其結果，作業者可不產生過大應力而將支持板牢固地安裝於支柱，並容易組裝框體。關於上述構成，上述支持板亦可包含自上述板本體部延伸設置於上述支柱側之至少1個側片。上述第1側片及上述第2側片亦可與上述至少1個側片協動，整體地包圍上述板本體部。根據上述構成，第1側片及第2側片至少與1個側片協動，且整體地包圍板本體部，因而頂板可具有高機械性強度。關於上述構成，上述支持板係連接於上述支柱之上端部之頂板，上述板本體部係與車輛之下表面對向之頂面板部，上述頂板亦可包含並排於上述第1側片且自上述頂面板部突出之第1補強肋、及並排於上述第2側片且自上述頂面板部突出之第2補強肋。根據上述構成，頂板係藉由第1補強肋及第2補強肋補強，因而頂板可具有高機械性強度。關於上述構成，用以將上述框體自上述下表面懸吊之懸吊連接體亦可連接於由上述第1側片、上述第2側片、上述舌片、上述第1補強肋及上述第2補強肋包圍之上述頂面板部之區域。根據上述構成，懸吊連接體所連接之頂面板部之區域係由第1側片、第2側片、舌片、第1補強肋及第2補強肋包圍，因而懸吊連接體所連接之頂面板部之區域可具有高機械性強度。關於上述構成，形成於上述頂面板部與上述第1側片之間之第1外彎折線亦可沿插通於上述第2開口部及上述第2連通孔之緊固具之延伸設置方向延伸。形成於上述頂面板部與上述第2側片之間之第2外彎折線亦可沿插通於上述第1開口部及上述第1連通孔之另1個緊固具之延伸設置方向延伸。另，該情形，形成於上述頂面板部與上述舌片之間之第3外彎折線亦可相對於第1及第2外彎折線傾斜。進而，第3外彎折線相對於第1及第2外彎折線之各者之傾斜角度亦可被設定為相等。根據上述構成，第1外彎折線沿插通於第2開口部及第2連通孔之緊固具之延伸設置方向延伸，因而若作業者緊固插通於第3開口部與第3連通孔之緊固具，則支柱朝第1側片移動，第1開口部適當地與第1連通孔重疊。因此，作業者可將另1個緊固具輕鬆地插通於第1連通孔及第1開口部，且將第1側片緊固於第1板部。第2外彎折線係沿插通於第1開口部及第1連通孔之另1個緊固具之延伸設置方向延伸，因而插通於第3開口部與第3連通孔之緊固具之緊固結果，支柱亦可朝第2側片移動。其結果，第2開口部適當重疊於第2連通孔。因此，作業者可將另1個緊固具輕鬆地插通於第2連通孔及第2開口部，且將第2側片緊固於第2板部。第1緊固具及第2緊固具之輕鬆插通之結果，於第1緊固具及第2緊固具之周圍，未產生過大應力。關於上述構成，上述第1補強肋亦可包含沿與上述第1外彎折線並排延伸之第1內彎折線而彎折之第1彎折肋、及以自上述第1彎折肋向上述第2側片延長之方式熔接於上述頂面板部之第1延長肋。上述第2補強肋亦可包含沿與上述第2外彎折線並排延伸之第2內彎折線而彎折之第2彎折肋、及以自上述第2彎折肋向上述第1側片延長之方式熔接於上述頂面板部之第2延長肋。根據上述構成，第1補強肋包含第1彎折肋與第1延長肋，因而用以形成第1補強肋之熔接加工之長度變短。第2補強肋包含第2彎折肋與第2延長肋，因而用以形成第2補強肋之熔接加工之長度變短。關於上述構成，上述框體亦可包含連接於上述頂板之蓋板。上述第1內彎折線及上述第2內彎折線亦可形成於上述頂面板部所形成之開口區域之輪廓之一部分。上述蓋板亦可封閉上述開口區域。根據上述構成，蓋板因封閉於頂面板部形成之開口區域，故壓縮機構由框體適當地保護。關於上述構成，上述框體亦可包含：(i)另1支柱，其與上述支柱協動而夾著上述2個側面中的一個；(ii)樑材，其於上述第1外彎折線及上述第2外彎折線中一者之下方，沿上述一者之外彎折線之延伸設置方向，於上述2個支柱間延伸；(iii)支持板，其支持上述壓縮機構；(iv)防振材，其由上述支持板與上述樑材夾著；及(v)緊固棒，其具有接觸上述樑材之接觸部以及自上述接觸部延伸並貫通上述樑材、上述支持板及上述防振材之貫通部。上述支持板亦可包含形成容許上述緊固棒貫通之貫通孔之輪廓之緣部。上述緣部亦可非接觸式地包圍上述貫通部。上述支持板亦可藉由上述防振材而與上述樑材隔開。根據上述構成，形成容許緊固棒貫通之貫通孔之輪廓的緣部係非接觸式包圍緊固棒之貫通部，因而自壓縮機構產生之振動不易通過緊固棒傳遞至樑材。支持板藉由防振材而與樑材隔開，因而自壓縮機構產生之振動因防振材而適當減弱。關於上述構成，上述框體亦可包含與上述防振材協動且夾著上述支持板之防振襯套。上述防振襯套亦可至少部分地填充上述緣部與上述貫通部之間之空隙。根據上述構成，防振襯套因至少部分地填充緣部與貫通部之間之空隙，故不易產生緊固棒與支持板之直接接觸。關於上述構成，上述框體亦可包含供插入上述緊固棒之墊圈。上述貫通部亦可包含貫通上述樑材、上述防振材、上述支持板及上述防振襯套之第1棒部、及較上述第1棒部更細之第2棒部。上述墊圈亦可由形成於上述第1棒部與上述第2棒部之間之階部支持，而與上述防振襯套隔開。根據上述構成，墊圈因由形成於第1棒部與第2棒部之間之階部支持，與防振襯套隔離，故自壓縮機構產生之振動不易通過緊固棒傳遞至樑材。又，本發明之一態樣之空氣壓縮裝置包含技術方案1至13中任一項所記述之框體、及收納於該框體之內部空間產生壓縮空氣之壓縮機構。根據上述構成，可利用上述各構成之框體構成空氣壓縮裝置。因此，該空氣壓縮裝置亦可與上述框體同樣，設為不易產生設計者不期望之過大應力者。<First Embodiment> In a housing in which a heavy object is housed, By fixing two members by a plurality of bolts inserted from a plurality of sides different from each other, For those who are not skilled in the assembly work, the bolts are tightened from the first root. With this, Since the relative positions of the above two members are fixed based on the first bolt, Therefore, the hole portions of the two members of the bolt inserted after the second root are not properly overlapped. If the unskilled operator subsequently forcibly inserts the second bolt into the two holes that are not properly overlapped, Excessive stress is generated around the bolt. If the assembly is fastened with a plurality of bolts, the weight is supported. Excessive stress is generated around the bolts and bolts that are forcibly inserted. This situation will eventually accelerate the metal fatigue of the two components. If the assembly is properly assembled, Then the two components are properly connected, High friction is obtained between the two components. High friction helps the support of heavy objects, Therefore, the stress around the bolt and the bolt is suppressed to a low level. therefore, If a plurality of bolts are fastened at appropriate relative positions between the two members, It will not cause excessive stress in the assembly body. The inventors have developed even an unskilled operator, It is also easy to perform proper assembly work, Moreover, it is not easy to form a fastening structure of the frame with excessive stress around the bolt. In the first embodiment, The fastening structure of the illustrated frame will be described. The fastening structure of the casing described in the first embodiment can be applied to various air compressing devices mounted on vehicles of railway vehicles or other moving bodies. Fig. 1 is a schematic perspective view of an assembly ASY including a pillar SPT and a top plate TPL. Figure 2 is a cross-sectional view of Figure 1. Referring to Figure 1, Describe the assembly ASY. The pillar SPT includes the first plate portion FPP, The second board SPP, And the third board part TPP. The first board FPP, The second plate portion SPP and the third plate portion TPP are long in the vertical direction. The third plate portion TPP is disposed between the first plate portion FPP and the second plate portion SPP. The width of the third plate portion TPP is narrower than the width of the first plate portion FPP and the width of the second plate portion SPP. The first plate portion FPP and the second plate portion SPP have a specific angle in a plan view. The third plate portion TPP is in a plan view, The first plate portion FPP has an arbitrary angle α larger than the specific angle of the first plate portion FPP and the second plate portion SPP (see FIG. 2). also, The third plate portion TPP is in a plan view, The second plate portion SPP has an arbitrary angle β larger than the specific angle of the first plate portion FPP and the second plate portion SPP (see FIG. 2 ). The specific angle of the first plate portion FPP and the second plate portion SPP, The sum of the outer angles of the above angles α and β is set to π. The third board TPP, Angle α of the first plate portion FPP or the second plate portion SPP, β can be different, However, in the present embodiment, the angles (α = β) are set to be substantially the same. The first board FPP, The second plate portion SPP and the third plate portion TPP are coordinated, Forming corners. At the upper end of the first plate FPP, The first opening portion FON is formed along the thickness direction. At the upper end of the second plate portion SPP, The second opening SON is formed along the thickness direction. At the upper end of the third plate TPP, The third opening portion TON is formed along the thickness direction. The first opening FON is formed to incorporate the first fastening tool extending in the first direction A. The second opening SON is formed to incorporate the second fastening tool extending in the second direction B different from the first direction A. The third opening TON is formed to incorporate a third fastening tool extending in the third direction C different from the first direction A and the second direction B. The first fastening device, Each of the second fastening device and the third fastening device may also be a bolt, rivet, Pins or other rod-like parts that can fasten the strut SPT and the top plate TPL. The principle of the embodiment is not limited to the first fastening device, The second fastening tool and the third fastening tool are used as specific parts. The first direction A, The second direction B and the third direction C and the respective opening portions FON, SON, The axes of TON are in the same direction a1 to a3. in particular, The directions of the axes a1 to a3 and the first to third plate portions FPP, SPP, The normal to the TPP (relative to the perpendicular to the plane) is uniform or parallel. Each opening FON, SON, The axes a1 to a3 of TON do not necessarily cross at 1 o'clock. But in the case of not crossing at 1 o'clock, In a case where at least one of the axes a1 to a3 moves in parallel and intersects at one point, The axis a3 of the third opening TON is located at an angle θ1 between the axis a1 of the first opening FON and the axis a2 of the second opening SON (the first plate portion FPP is formed, Between the second plate portion SPP and the corner of the corner portion of the third plate portion TPP. In this embodiment, Each opening FON, SON, Each axis a1 to a3 of TON crosses at 1 o'clock even if it does not move in parallel. The axis a1 set to the first opening FON is orthogonal to the axis a2 of the second opening SON. also, The axis a3 of the third opening TON is set to be the axis a1 of the first opening FON. The bisector of the angle θ1 formed by the axis a2 of the second opening SON coincides. which is, The angle θ2 between the axis a3 of the third opening TON and the axis a1 of the first opening FON and the axis a3 of the third opening TON and the axis a2 of the second opening SON are formed. The angle θ3 of the 隅 side of the corner is equal. In the first fastening device, If the second fastening device and the third fastening device use bolts, Then the top plate TPL is easily removed from the strut SPT. therefore, The operator can easily perform maintenance on the machine surrounded by the assembly ASY. The top plate TPL includes a top panel portion TSP, The first side piece FSF, The second side piece SSF, And tongue TGF. The top panel portion TSP is substantially horizontal and transverse. The first side piece FSF, Each of the second side panel SSF and the tongue piece TGF is continuous with the top panel portion TSP and separated from each other. The first side panel FSF is bent downward from the top panel portion TSP by being bent from the top panel portion TSP. And overlapping the outer surface of the first plate portion FPP. The second side panel SSF is bent downward from the top panel portion TSP by being bent from the top panel portion TSP. And overlapping the outer surface of the second plate portion SPP. The tongue piece TGF is extended downward from the top panel portion TSP by being bent from the top panel portion TSP. And overlapping the outer surface of the third plate portion TPP. In a state in which the tongue TGF overlaps the outer surface of the third plate portion TPP, The first and second side sheets FSF, SSF overlaps both the first and second plate portions FPP, SPP. which is, The first side piece FSF, The second side piece SSF, And the normal line of the tongue TGF and the first plate portion FPP of the pillar SPT, The second board SPP, And the normals of the third plate TPP are the same (including the same). which is, The bending line between the tongue piece TGF and the top panel portion TSP is bent from a bending line between the first side panel FSF and the top panel portion TSP. same, The bending line between the tongue piece TGF and the top panel portion TSP is bent from a bending line between the second side panel SSF and the top panel portion TSP. In this embodiment, The angle between the bending line formed by the boundary between the tongue TGF and the top panel portion TSP and the bending line formed by the boundary between the first side panel FSF and the top panel portion TSP may also be the boundary between the tongue TGF and the top panel portion TSP. The angle between the formed bending line and the bending line formed by the boundary between the second side panel SSF and the top panel portion TSP substantially coincides. At the end of the TGF side of the tongue of the first side panel FSF, The first communication hole FCH is formed in the thickness direction. The first communication hole FCH overlaps with the first opening FON. At the end of the TGF side of the tongue of the second side panel SSF, The second communication hole SCH is formed in the thickness direction. The second communication hole SCH overlaps with the second opening SON. In the center of the tongue TGF, The third communication hole TCH is formed in the thickness direction. The third communication hole TCH overlaps with the third opening TON. In this case, The first communication hole FCH, The second communication hole SCH, The axis of the third communication hole TCH and the first opening FON, The second opening SON, The axes a1 to a3 of the third opening TON match or substantially coincide with each other. therefore, In Figure 2, Regarding the respective axes of the communication holes FCH to TCH, Also with the opening FON of FIG. 2, SON, The axes a1 to a3 of the TON axes a1 to a3 are the same. which is, The axes a1 to a3 of the respective communication holes FCH to TCH are as shown in FIG. 2 . The height position or horizontal position of each of the communication holes FCH to TCH does not necessarily cross at 1 point. But in the case of not crossing at 1 o'clock, When the axes a1 to a3 are moved in parallel and intersect at one point, The axis a3 of the third communication hole TCH is located at an angle θ1 between the axis a1 of the first communication hole FCH and the axis a2 of the second communication hole SCH (the first plate portion FPP, Between the second plate portion SPP and the corner of the corner portion formed by the third plate portion TPP. In this embodiment, Each communication hole FCH, SCH, Each axis a1 to a3 of the TCH crosses at 1 o. The axis a1 of the first communication hole FCH is set to be orthogonal to the axis a2 of the second communication hole SCH. also, The axis a3 of the third communication hole TCH is set to coincide with the bisector of the angle θ1 formed by the axis a1 of the first communication hole FCH and the axis a2 of the second communication hole SCH. which is, The angle θ2 between the axis a3 of the third communication hole TCH and the axis a1 of the first communication hole FCH and the axis a3 of the third communication hole TCH and the axis a2 of the second communication hole SCH are formed. The angle θ3 of the 隅 side of the corner is equal. The operator places the top plate TPL on the pillar SPT. at this time, The first side piece FSF, The second side panel SSF and the tongue piece TGF may also be slightly away from the pillar SPT. The principle of the present embodiment does not require high precision for the bending process applied to the top plate TPL. The operator first inserts the third fastening tool into the third communication hole TCH and the third opening TON. If the operator tightens the third fastening device afterwards, Then the pillar SPT is relatively displaced for the top plate TPL, The first opening FON is automatically superposed on the first communication hole FCH (including the case where the first opening is substantially overlapped). same, The second opening SON is automatically superposed on the second communication hole SCH (including the case where the second communication hole is substantially overlapped). The angle between the bending line formed by the boundary between the tongue TGF and the top panel portion TSP and the bending line formed by the boundary between the first side sheet FSF and the top panel portion TSP is at the boundary between the tongue TGF and the top panel portion TSP. The angle between the bending line formed by the boundary line of the second side piece SSF and the top panel portion TSP is substantially the same. The relative displacement of the first opening FON with respect to the first communication hole FCH and the relative displacement of the second opening SON with respect to the second communication hole SCH are substantially equal. however, Generally, each communication hole FCH, SCH, TCH for each opening FON, SON, The relative position of TON is mostly based on workability or tolerance without strict alignment. therefore, When the first opening FON and the first communication hole FCH are used as a reference, the alignment between the pillar SPT and the top plate TPL is performed. There is a case where the pillar SPT is biased to one side in the first direction A with respect to the top plate TPL. If the offset is generated, There is a second opening SON formed in the second plate portion SPP orthogonal to the first plate portion FPP, The positional deviation between the second communication hole SCH formed in the second side piece SSF orthogonal to the first side piece FSF is increased. Based on the position offset, There is a case where the stress around the second fastening tool and the second fastening tool becomes high. Based on the second opening SON and the second communication hole SCH, The same applies to the case where the pillar SPT is aligned with the top plate TPL. That point, In this embodiment, The assembly ASY includes a pillar SPT, And a top plate TPL connected to the upper end of the pillar SPT, The pillar SPT includes a first plate portion FPP and a second plate portion SPP, And the third plate portion TPP having an angle larger than the angle between the first plate portion FPP and the second plate portion SPP for each of the first plate portion FPP and the second plate portion SPP in plan view, The top plate TPL includes a top panel portion TSP, The first side panel FSF which is bent from the top panel portion TSP and superposed on the first panel portion FPP, The second side panel SSF which is bent from the top panel portion TSP and superposed on the second panel portion SPP, And the tongue TSF which is bent from the top panel portion TSP between the first side panel FSF and the second side panel SSF and superposed on the third panel portion TPP, On the first side sheet FSF, Each of the second side panel SSF and the tongue piece TSF, Each of the openings FON formed in the pillar SPT is formed, SON, TON, each of the overlapping communication holes FCH, SCH, TCH, Therefore, even if the openings are FON, SON, TON or each communication hole FCH, SCH, TCH is not closely aligned based on tolerances, etc. In the case of initially tightening the third fastening device, Compared with the case where the first or second fastening device is initially tightened, It can also alleviate the above offset. In other words, In this embodiment, In the first and second plate portions FPP of the above configuration, The third board part TPP is set between the SPPs, And in the first and second side sheets FSF, The tongue TGF is set between the SSFs, The axis a3 of the third opening portion TON of the third plate portion TPP, Or the axis a3 of the third communication hole TCH of the tongue TGF is set to be the first and second plate portions FPP, Each opening of the SPP is FON, Axis of SON a1 Angle of a2 θ1 Or the first and second side sheets FSF, Each of the SSF's communication holes FCH, SCH axis a1 The angle θ1 of the a2 is equal to the bisector. So even if it is not strictly aligned, Also shown in the chain of two points in Figure 2, In the case of initially tightening the third fastening device, Compared with the case where the first or second fastening device is initially tightened, Can also alleviate the above offset, Thereby, the relative displacement of the first opening portion FON with respect to the first communication hole FCH, The relative displacement of the second opening portion SON with respect to the second communication hole SCH can be set to be small and substantially uniform. The positional deviation between the first communication hole FCH and the first opening FON is small. The two overlap, Therefore, the operator can easily insert the first fastening tool into the first communication hole FCH and the first opening FON. same, The operator can easily insert the second fastening tool into the second communication hole SCH and the second opening SON. If the operator complies with the assembly rules for tightening the third fastener before other fasteners, Then the first and second fastening tools, And the stress around the fasteners will be suppressed to a low degree, The operator can mount the top plate TPL to the strut SPT without excessive stress on the top plate TPL. If the first fastening device, Each of the second fastening device and the third fastening device uses a bolt, Then, the first side sheet FSF is in surface contact with the first plate portion FPP. Further, the second side piece SSF is in surface contact with the second plate portion SPP. therefore, A strong frictional force is generated between the first side panel FSF and the first panel portion FPP and between the second side panel SSF and the second panel portion SPP. the result, The top plate TPL is firmly connected to the pillar SPT. <Second Embodiment> The structure described in the first embodiment can be preferably used in various air compressing devices. general, The air compression device is suspended from the lower surface of the railway vehicle by a top plate. therefore, The weight of the compression mechanism disposed inside the casing is mostly applied to the top plate via the pillars. which is, The load is concentrated on the fastening portion between the pillar and the top plate (for example, The weight of the compression mechanism). If the railway vehicle is assembled before the frame, Excessive stress between the top plate and the pillar when it is assembled, There is a load that is more than the load-bearing load of the top plate desired by the designer of the design air compression device applied to the top plate. As described in the first embodiment, The structure of the top plate having the tongue piece is less likely to cause excessive stress on the top plate, Therefore, it is not easy to cause damage to the top plate or the pillar. According to the principle described in the first embodiment, If the operator follows the sequence of the work of fastening the tongue first, Then, the two pieces of metal pieces (the first side piece and the second side piece described in the first embodiment) which are formed by the cooperation of the tongue pieces are easily balanced by the load (the one of the two pieces of the metal piece is excessively applied) The risk of load is reduced).

The diameter of the through hole 684 is larger than the diameter of the lower portion 935 of the main body portion 932. therefore, The beam 683 is not easily contacted with the bolt 930. the result, The vibration transmission from the bolt 930 to the beam 683 is not easily generated. The inner diameter of the anti-vibration ring 910 is substantially equal to the diameter of the lower portion 935 of the main body portion 932. The anti-vibration ring 910 is not in contact with the upper portion 936 of the main body portion 932. Therefore, the amount of vibration transmitted from the anti-vibration ring 910 toward the bolt 930 is only a small amount. In this embodiment, The fastening rod is illustrated by bolt 930. The contact portion is exemplified by the head 931. The through portion is composed of the main body portion 932, A screw portion 933 extending upward from the main body portion 932 is exemplified. The ear portion 692 includes an edge portion 694 defining a through hole 693 into which the main body portion 932 is inserted. The diameter of the through hole 693 is larger than the diameter of the main body portion 932. therefore, The edge portion 694 is less likely to contact the bolt 930. the result, It is not easy to generate vibration transmission from the ear portion 692 toward the bolt 930. The vibration isolating bushing 920 includes a lower ring portion 921 and an upper ring portion 922. The inner diameter of the upper ring portion 922 is the same as the inner diameter of the lower ring portion 921. on the other hand, The outer diameter of the upper ring portion 922 is larger than the outer diameter of the lower ring portion 921. The lower ring portion 921 protrudes downward from the upper ring portion 922. A thin annular space between the edge portion 694 of the ear portion 692 and the body portion 932 of the bolt 930 is filled. the result, Ear 692 is properly positioned for bolt 930. The outer diameter of the screw portion 933 is smaller than the diameter of the main body portion 932. therefore, A step 934 is formed at a boundary between the main body portion 932 and the screw portion 933. In this embodiment, The first rod portion is exemplified by the main body portion 932. The second rod portion is exemplified by the screw portion 933. The washer 940 includes a lower portion 941 that surrounds the front end of the body portion 932 of the bolt 930, And surrounding the base portion 942 of the base end of the screw portion 933 of the bolt 930. The inner diameter of the lower portion 941 of the washer 940 is smaller than the diameter of the main body portion 932. Thus the height position of the washer 940 is determined by the position of the step 934. As shown in Figure 9, Between the lower surface of the gasket 940 and the upper surface of the anti-vibration bushing 920, A thin void is formed. the result, The vibration transmission from the anti-vibration bushing 920 toward the washer 940 is not easily generated.
