Hydraulic pile hammer with barrel type swing support
The invention discloses a hydraulic pile hammer with barrel type swing support. A plurality of barrel body through windows are arranged on a hammer barrel body; a barrel body vertical rib is fixedly arranged on the outer barrel surface of the hammer barrel body; a plurality of cylinder body oil holes are formed in the cylinder body of a hydraulic cylinder; the cylinder body oil holes are parallelto a cylinder body barrel cavity and are formed around the cylinder body barrel cavity; the lower ends of the cylinder body oil holes communicate with the cylinder body barrel cavity; the lower end ofa piston rod is in hinged connection to a hammer core; the cylinder body is supported to the upper end of the hammer barrel through a cylinder body swing support structure; the cylinder body swing support structure comprises a cylinder body swing shaft and a swing frame pin roll; the cylinder body is movably supported on a swing frame through the cylinder body swing shaft; the swing frame is movably supported on the cylinder body swing base through the swing frame pin roll; the cylinder body swing base is fixedly mounted at the upper end of the hammer barrel body; and a ratio of mass t of thehammer core to total mass T of the pile hammer is t/T equal to 60%-80%. The hydraulic pile hammer is high in hamming energy and frequency, is small in hammer core gas resistance, and can effectivelycompensate and eliminate lateral motion component force of the cylinder body piston.
本发明公开了一种筒式摆支液压打桩锤，在锤筒本体上设置有若干筒体透窗，锤筒本体外筒面上固定设置有筒体竖筋；液压缸缸体上设置有若干缸体油孔，缸体油孔平行于缸体筒腔并围绕缸体筒腔布置，缸体油孔的下端与缸体筒腔连通；所述活塞杆的下端与锤芯相铰连，所述缸体通过缸体摆动支承结构支承于锤筒的上端，该缸体摆动支承结构包括缸体摆轴和摆框销轴，缸体通过缸体摆轴活动支承于摆动框上，该摆动框则通过摆框销轴活动支承于缸体摆座上，缸体摆座固定安装于锤筒本体的上端；所述锤芯的质量t与打桩锤总质量T之比t/T=60%—80%。该液压打桩锤，不仅打击能量和频次高，锤芯气阻小，而且能有效补偿和消除缸体活塞间的侧向运动分力。
