DZ60振動(dòng)打樁錘的設(shè)計(jì)畢業(yè)論文.doc

I摘要振動(dòng)樁錘是慣性振動(dòng)機(jī)械的一種，屬于振動(dòng)利用機(jī)械中的平面雙軸式激振器。振動(dòng)樁錘是利用機(jī)械振動(dòng)減少樁與土壤間的摩擦力，并依靠其自重或外加壓力作用下達(dá)到沉樁的目的。振動(dòng)樁錘分機(jī)械式和液壓式兩類，液壓振動(dòng)錘應(yīng)用較少。振動(dòng)樁錘采用機(jī)械式定向激振器。它由兩根裝有相同的偏心塊并相向轉(zhuǎn)動(dòng)的軸組成，兩根軸上的偏心塊所產(chǎn)生的離心力在水平方向上的分力相互抵消，而垂直方向上的分力疊加。振動(dòng)樁錘主要由電動(dòng)機(jī)、導(dǎo)桿、壓縮彈簧、減振粱、振動(dòng)箱、皮帶輪等組成。具有貫入力強(qiáng)、沉樁質(zhì)量好、堅(jiān)固耐用、故障少、結(jié)構(gòu)緊湊、低噪音、高效率、無(wú)污染等優(yōu)點(diǎn)。關(guān)鍵詞：振動(dòng)機(jī)械、振動(dòng)樁錘、慣性振動(dòng)、減振彈簧IIAbstractThevibrationhammerisonekindoftheinertialoscillationmachinery,belongstointhevibrationusemachinerytheplanedoubleshafttypedriver.Thevibrationhammerusesfrictiontoreducetheforcebetweenthemechanicalvibrationspileandthesoil,anddependsuponittobeself-possessedorthesur-pressurefunctionissuesthegoalofstakesinking.Thevibrationhammerdividesthemechanicaltypeandthehydraulicpressuretypetwokinds,thehydraulicpressurevibrationhammerapplicationareless.Thevibrationhammerusesthemechanicaltypedirectiondetectiondriver.Itisloadedwithsamelackofimpartialitythepieceandtheoppositedirectionrotationaxisbytwoiscomposed,ontwoaxeslackofimpartialitythepieceproducesthecentrifugalforceoffsetsorcounteractoneanotherinthehorizontalsideupwardforcecomponent,butinverticaldirectionforcecomponentsuperimposition.Thevibrationhammermainlybytheelectricmotor,theguiderod,thecompressionspring,horizontalbeamreducinginspires,avibrationboxofbody,thebeltpulleyandsooniscomposed.Hasthepenetratingpowerstrongly,thequalityofstakesinkingisgood,firmdurable,thebreakdownfew,thestructureiscompact,thelownoise,thehighefficiency,doesnothavemeritandsoonpollution.Keywords:VibratesthemachineryVibratorypilehammertheinertialoscillationthespringreducinginspiresIII目錄摘要.IABSTRACT.II第1章緒論.1第2章振動(dòng)機(jī)械的用途、分類、工作原理及構(gòu)造.22.1振動(dòng)機(jī)械的用途和分類.22.1.1振動(dòng)機(jī)械的組成.22.1.2振動(dòng)機(jī)械的用途.32.1.3振動(dòng)機(jī)械的分類.42.2慣性振動(dòng)機(jī)械的工作原理與構(gòu)造.52.2.1慣性激振器的形式.52.2.3線性或近似線性的近共振類慣性機(jī)械.122.2.4非線性慣性振動(dòng)機(jī)械.132.2.5沖擊式慣性振動(dòng)機(jī)械.142.3樁工機(jī)械的分類和工程應(yīng)用.142.3.1樁工機(jī)械的分類.152.3.2樁工機(jī)械在工程技術(shù)中的應(yīng)用.152.4振動(dòng)樁錘的工作原理和構(gòu)成.152.4.1振動(dòng)樁錘的工作原理.152.4.2振動(dòng)樁錘的構(gòu)成.172.4.3沉樁原理.18第3章電機(jī)的選擇和計(jì)算.20IV3.1選擇電動(dòng)機(jī)應(yīng)綜合考慮的問(wèn)題.203.2選擇電動(dòng)機(jī).20第4章振動(dòng)樁錘的主參數(shù)計(jì)算.224.1激振力的計(jì)算.224.2計(jì)算實(shí)際振幅.234.2.1根據(jù)提供的頻率選擇工作土壤的類型.234.2.2振幅A的確定.234.3計(jì)算實(shí)際偏心力矩.244.4功率的計(jì)算.25第5章減振彈簧的設(shè)計(jì)與計(jì)算.275.1減振彈簧的結(jié)構(gòu)選擇.275.1.1選取螺旋彈簧的類型代號(hào).275.1.2選取彈簧的材料并確定其主要性能參數(shù).275.2圓柱螺旋彈簧的設(shè)計(jì)計(jì)算.275.2.1確定單根彈簧的最大工作載荷.275.2.2選擇旋繞比.285.2.3計(jì)算鋼絲直徑.285.2.4計(jì)算彈簧中徑.285.2.5計(jì)算彈簧圈數(shù).295.
