Double-hydraulic-cylinder type hydraulic impact hammer
The double-hydraulic-cylinder type hydraulic impact hammer comprises a hammer body frame, an impact hammer core, a double-hydraulic-oil-cylinder set, a pile cap set and a hydraulic control system, the bottom of the hammer body frame is connected with the pile cap set, the impact hammer core is arranged in an inner cavity of the hammer body frame, and the top of the impact hammer core is connected with the double-hydraulic-oil-cylinder set. The double-hydraulic-oil-cylinder set is connected with the hammer body frame through a supporting base and comprises two hydraulic cylinders arranged in parallel, and each hydraulic cylinder comprises a cylinder barrel, an upper valve block, a piston rod, a lower valve block, a hydraulic communicating pipe I and a hydraulic communicating pipe II. The upper portion of the cylinder barrel is connected with the upper valve block, the lower portion of the cylinder barrel is connected with the lower valve block, the upper valve blocks of the two hydraulic cylinders are connected through the hydraulic communicating pipe I, and the lower valve blocks of the two hydraulic cylinders are connected through the hydraulic communicating pipe II. And the hydraulic control system drives the two hydraulic cylinders to synchronously act, so that piston rods of the two hydraulic cylinders can synchronously drive the impact hammer core to move. The device is good in overall synchronism and high in hammering impact energy.
本发明涉及一种双液压缸式液压冲击锤，包括锤体框架、冲击锤芯、双液压油缸组、桩帽组及液压控制系统，锤体框架的底部连接桩帽组，冲击锤芯置于锤体框架的内腔中，冲击锤芯的顶部连接双液压油缸组，双液压油缸组通过支撑座与锤体框架连接，双液压油缸组包括平行设置的两个液压缸，液压缸包括缸筒、上阀块、活塞杆、下阀块、液压连通管I、液压连通管II；缸筒的上方连接上阀块，缸筒的下方连接下阀块，液压连通管I将两个液压缸的上阀块相连接，液压连通管II将两个液压缸的下阀块相连接；液压控制系统驱动两个液压缸同步动作，使两个液压缸的活塞杆能够同步带动冲击锤芯运动。本发明整体同步性好、打锤冲击能量高。
