Split type multi-cylinder single-action pneumatic pile hammer
The invention discloses a split type multi-cylinder single-action pneumatic pile hammer, and relates to the technical field of pile drivers, the split type multi-cylinder single-action pneumatic pile hammer comprises a fixed block, a heavy hammer, a pile cap, an air inlet control unit, at least two guide rods and a plurality of cylinders, the top ends of the guide rods are fixedly connected with the fixed block, and the bottom ends of the guide rods are fixedly connected with the pile cap; the heavy hammer is slidably arranged on the guide rod in a sleeving mode, cylinder bodies of the air cylinders are fixedly connected with the pile cap, and the free end of a piston rod of each air cylinder is fixedly connected with the heavy hammer. The air inlet control unit comprises a stroke scale, an upper stroke limiting switch, a lower stroke limiting switch and a pneumatic two-position three-way valve. The stroke scale is provided with an upper contact used for turning on the upper stroke limiting switch and a lower contact used for turning on the lower stroke limiting switch. A working port A of the pneumatic two-position three-way valve is communicated with an air inlet of each air cylinder, an air inlet P is communicated with a high-pressure air source through a connecting pipe, and an exhaust port R is connected with a silencer. And by arranging the multiple air cylinders, the striking energy of the pneumatic pile hammer is improved.
本发明公开一种分体式多气缸单作用气动打桩锤，涉及打桩机技术领域，包括固定块、重锤、桩帽、进气控制单元、至少两个导杆和多个气缸，导杆的顶端与固定块固连，导杆的底端与桩帽固连；重锤滑动套设在导杆上，气缸的缸体都与桩帽固连，每个气缸的活塞杆的自由端都与重锤固连；进气控制单元包括行程标尺、上行程限位开关、下行程限位开关和气动二位三通阀，行程标尺上设置有用于开启上行程限位开关的上触点和用于开启下行程限位开关的下触点；气动二位三通阀的工作口A与每个气缸的进气口连通，进气口P通过连接管与高压气源连通，排气口R连接有消声器。通过设置多个气缸提高了气动打桩锤的打击能量。
