Embedded hydraulic pile hammer core
The embedded hydraulic pile hammer core comprises a hammer core shaft, a piston assembly and a balance weight, the hammer core shaft comprises a piston section, a balance weight section and a hammering section which are arranged from top to bottom, the balance weight is embedded in the outer layer of the balance weight section, the piston assembly is arranged at the top of the piston section, and a hammer head is arranged at the bottom end of the hammering section. The problems that a hammer core of an existing large hydraulic pile hammer is large in forging difficulty and heat treatment difficulty and long in machining period are effectively solved, and when the weight of the hammer core exceeds 200 tons, it can still be guaranteed that the large hydraulic pile hammer is safely and reliably used.
本发明的目的是提供一种镶嵌式液压打桩锤锤芯，包括锤芯轴、活塞组件和配重，所述锤芯轴包括自上而下设置的活塞段、配重段和锤击段三段，所述配重镶嵌在配重段外层，所述活塞组件设于活塞段顶部，所述锤击段底端设有锤头。本发明有效解决现有大型液压打桩锤的锤芯锻造难度大、热处理困难和加工周期长的问题，当锤芯重量超过200吨时，仍能保证大型液压打桩锤安全可靠使用。
