Hydraulic breaking hammer
The invention discloses a hydraulic breaking hammer, which belongs to the field of hydraulic elements, and mainly comprises a shell, a reversing valve core, a drill rod, an energy storage air bag, a piston mechanism and an impact mechanism, and the piston mechanism can be switched between a locking state and an unlocking state; the impact mechanism is arranged in the shell in a sliding mode, the reversing valve element drives the impact mechanism to impact the drill rod, and the impact mechanism drives the piston mechanism to change the working state in the working process. The reversing valve core not only controls the reciprocating impact action of the piston body, but also impacts the drill rod during switching, so that the impact frequency of the hydraulic breaking hammer is improved; when the piston body reciprocates, the impact action of the small piston is realized, so that the impact frequency is increased, the movement times of the piston body and the reversing valve core are reduced under the same impact frequency, the abrasion is reduced, and the service life is prolonged; the structure is simple, and control is convenient.
本发明公开了一种液压破碎锤，属于液压元件领域，其主要由壳体、换向阀芯、钎杆、蓄能气囊、活塞机构和冲击机构组成，其中活塞机构可在锁定状态和解锁状态间切换工作；冲击机构滑动设置在壳体内，换向阀芯传动冲击机构对钎杆进行冲击，冲击机构工作过程中驱动活塞机构改变工作状态；本发明换向阀芯不仅控制活塞体往复冲击动作，并且在切换的同时也对钎杆进行冲击，进而提高了本发明液压破碎锤的冲击频率；并且在活塞体往复运动的同时，实现小活塞的冲击动作，进而增加本发明的冲击频率，使得在相同冲击频率下，活塞体和换向阀芯的运动次数变少，进而减少磨损，延长使用寿命；同时结构简单，控制方便。
