Cam type drop hammer pile driver
The invention discloses a cam type drop hammer pile driver which comprises a hammer frame and a hammer core, the hammer core is movably supported on the hammer frame, a hammer lifting motor is fixedly installed on the hammer frame, the hammer lifting motor drives the hammer core through a hammer lifting cam mechanism, hammer lifting spiral ribs are arranged on the hammer lifting cam mechanism, and the hammer lifting spiral ribs are arranged on the hammer lifting cam mechanism. The projection wrap angle alpha of the hammer lifting spiral ribs on the plane perpendicular to the movement direction of the hammer core is smaller than 360 degrees. According to the cam type drop hammer pile driver, clutch or brake operation is not needed, the pile driving efficiency is high, the structure is simple, and hammer lifting and drop hammer hitting can be conveniently achieved.
本发明公开了一种凸轮式落锤打桩机，它包括锤架和锤芯，锤芯活动支承于锤架上，在所述锤架上固定安装有提锤电机，该提锤电机通过提锤凸轮机构驱动锤芯，所述提锤凸轮机构上设置有提锤螺旋棱条，该提锤螺旋棱条在垂直于锤芯运动方向的平面上的投影包角α小于360°。该凸轮式落锤打桩机不仅无需进行离合或制动操作，打桩效率高，而且结构简单，能够方便地实现提锤和落锤打击。
