Low-noise hydraulic pile hammer
The invention discloses a low-noise hydraulic pile hammer. The low-noise hydraulic pile hammer comprises a hammer outer frame lower section, a machine frame upper beam plate is arranged over the hammer outer frame lower section, stand columns are vertically and fixedly connected between the corners of the hammer outer frame lower section and the corners of the machine frame upper beam plate, the top of the hammer outer frame lower section is fixedly connected with an outer frame surrounding the sets of stand columns, a lifting cylinder fixing plate is arranged below the machine frame upper beam plate, and a lifting oil cylinder is vertically installed on the lifting cylinder fixing plate. The low-noise hydraulic pile hammer is simple in structure, convenient to operate and suitable for pile driving operation of tubular piles, the pile driving process meets the green and environment-friendly requirements of low carbon and energy conservation and is small in noise pollution, high in efficiency, high in pile forming rate and high in operation safety; after a heavy hammer assembly is lifted to the expected height through the lifting oil cylinder, a hammer falls rapidly, a hydraulic differential loop design enables the hammer falling speed to be higher, the hammer directly acts on a transition block below the heavy hammer assembly in a mode larger than a free falling body mode, and the piling efficiency of the tubular piles is improved advantageously.
本发明公开了打桩锤技术领域的一种低噪音液压打桩锤，包括锤外框下段，所述锤外框下段的正上方设置有机框上梁板，所述锤外框下段与机框上梁板的各边角之间竖直固接有立柱，所述锤外框下段的顶部固接有包围各组立柱的外框架，所述机框上梁板的下方设置有提升缸固定板，所述提升缸固定板上竖直安装有提升油缸，本发明结构简单，操作方便，适用于管桩的打桩操作，打桩过程不仅符合低碳、节能的绿色环保要求，且噪音污染小，效率高，成桩率高，操作安全性高；通过重锤组件通过提升油缸提升至预期高度后快速落锤，液压差动式回路设计使其落锤速度更快，以大于自由落体方式直接作用于重锤组件下方的过渡块上，有利于提升管桩的打桩效率。
