精品文档---下载后可任意编辑振动桩锤是惯性振动机械的一种，属于振动利用机械中的平面双轴式激振器。振动桩锤是利用机械振动减少桩与土壤间的摩擦力，并依靠其自重或外加压力作用下达到沉桩的目的。振动桩锤分机械式和液压式两类，液压振动锤应用较少。振动桩锤采纳机械式定向激振器。它由两根装有相同的偏心块并相向转动的轴组成，两根轴上的偏心块所产生的离心力在水平方向上的分力相互抵消，而垂直方向上的分力叠加。振动桩锤具有贯入力强、沉桩质量好、坚固耐用 、故障少、结构紧凑、低噪音、高效率、无污染等优点。AbstractThe vibrationis one kind of the inertial oscillation machinery, belongs to in the vibration use machinery the plane double shaft type driver. The vibration uses friction to reducethe force between the mechanical vibrations pile and the soil, and depends upon it to be self-possessed or the sur- pressure function issues the goal. The vibration divides the mechanical type and the hydraulic pressure type two kinds, the hydraulic pressure vibration hammer application are less. The vibration uses the mechanical type direction detection driver. It is loaded with same and the opposite direction rotation axis by two is composed, on two axes produces the centrifugal force offsets or counteract one another in the horizontal side upward force component, but in vertical direction force component superimposition. The vibration mainly by the electric motor, the guide rod, the compression spring, horizontal beam reducing inspires, vibration, the belt pulley and so on is composed. Has the penetrating power strongly, the quality of stake sinking is good, firm durable, the breakdown few, the structure is compact, the low noise, the high efficiency, does not have merit and so on pollution.Key words: Vibrates the machineryVibratory pile hammerthe inertial oscillationthe spring reducing inspires目 录摘要 IABS...
