I摘要振動樁錘是慣性振動機械的一種，屬于振動利用機械中的平面雙軸式激振器。振動樁錘是利用機械振動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到沉樁的目的。振動樁錘分機械式和液壓式兩類，液壓振動錘應(yīng)用較少。振動樁錘采用機械式定向激振器。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。振動樁錘主要由電動機、導(dǎo)桿、壓縮彈簧、減振粱、振動箱、皮帶輪等組成。具有貫入力強、沉樁質(zhì)量好、堅固耐用、故障少、結(jié)構(gòu)緊湊、低噪音、高效率、無污染等優(yōu)點。關(guān)鍵詞：振動機械、振動樁錘、慣性振動、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章振動機械的用途、分類、工作原理及構(gòu)造.22.1振動機械的用途和分類.22.1.1振動機械的組成.22.1.2振動機械的用途.32.1.3振動機械的分類.42.2慣性振動機械的工作原理與構(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械.122.2.4非線性慣性振動機械.132.2.5沖擊式慣性振動機械.142.3樁工機械的分類和工程應(yīng)用.142.3.1樁工機械的分類.152.3.2樁工機械在工程技術(shù)中的應(yīng)用.152.4振動樁錘的工作原理和構(gòu)成.152.4.1振動樁錘的工作原理.152.4.2振動樁錘的構(gòu)成.172.4.3沉樁原理.18第3章電機的選擇和計算.20IV3.1選擇電動機應(yīng)綜合考慮的問題.203.2選擇電動機.20第4章振動樁錘的主參數(shù)計算.224.1激振力的計算.224.2計算實際振幅.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計算實際偏心力矩.244.4功率的計算.25第5章減振彈簧的設(shè)計與計算.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.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)計計算.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計算鋼絲直徑.285.2.4計算彈簧中徑.285.2.5計算彈簧圈數(shù).295.
