Pile hammer rotation hydraulic system and pile hammer
The invention relates to a pile hammer, and provides a pile hammer rotation hydraulic system and a pile hammer in order to solve the problem of rotation limiting of an existing pile hammer. The rotation hydraulic system comprises a rotation motor and a rotation control valve. Two limiting valves connected in series are connected between two working oil ports of the rotation motor. When the two limiting valves are in a normal position, the limiting valves are in one-way switch-on in the direction of the working oil ports of the rotation motor connected with the limiting valves, and when the two limiting valves are in a limiting reversing position, the limiting valves are switched on. According to the pile hammer rotation hydraulic system and the pile hammer, when the rotation motor drives the pile hammer to rotate to a preset angle, the corresponding limiting valves are triggered to be reversed, and the oil inlet end and the oil outlet end of the rotation motor are in short-circuit connection and stop rotating. According to the pile hammer rotation hydraulic system and the pile hammer, rotation of the pile hammer is limited by the hydraulic system, the structure is simple and reliable, and limiting impact is avoided.
本发明涉及打桩锤，为解决现有打桩锤回转限位的问题；提供一种打桩锤回转液压系统和打桩锤，其中回转液压系统包括回转马达、回转控制阀，在回转马达的两工作油口之间连接有两个串联的限位阀，两限位阀处于常态位时限位阀向与其连接的回转马达工作油口方向单向导通，处于限位换向位时所述限位阀导通。在本发明中，当回转马达驱动打桩锤转动至预定角度时，对应的限位阀被触发换向，回转马达的进油端与出油端之间短路连接而停转。在本发明中，打桩锤的回转由液压系统进行限位，其结构简单可靠，不具有限位冲击。
