Resonance-free hydraulic vibration hammer
The invention belongs to the technical field of engineering machinery, and discloses a resonance-free hydraulic vibration hammer which comprises a vibration reduction frame, a resonance-free vibration gearbox, a cross beam and a pile clamping device, the cross beam is installed below the vibration reduction frame through the resonance-free vibration gearbox, and the pile clamping device comprises two pile clamping oil cylinders and two clamps. The two clamps are installed below the cross beam through the two pile clamping oil cylinders correspondingly. The resonance-free vibration gear box comprises a box body, a gear phase converter, an eccentric gear set, a transition gear, a first driving assembly and a second driving assembly, through scientific structural design, the gear phase converter is arranged in the vibration gear box, and when two sets of paired gear eccentric blocks are started and shut down, the eccentric gear set is driven by the transition gear to rotate; the relative positions of the gear eccentric blocks are adjusted through the gear phase converters, so that the vertical exciting force and the horizontal exciting force generated by the gear eccentric blocks are mutually counteracted. The eccentric torque is adjusted in the starting or stopping process of the hydraulic vibration hammer, and the resonance phenomenon of the vibration hammer in the starting or stopping process is eliminated.
本发明属于工程机械技术领域，公开了一种免共振液压振动锤，包括减振架、免共振振动齿轮箱、横梁、夹桩器，横梁通过免共振振动齿轮箱安装在减振架的下方，夹桩器包括二个夹桩油缸、二个夹具，二个夹具分别通过二个夹桩油缸安装在横梁的下方；免共振振动齿轮箱包括箱体、齿轮相位变换器、偏心齿轮组、过渡齿轮、第一驱动总成、第二驱动总成，通过科学的结构设计，在振动齿轮箱内设有齿轮相位变换器，两组成对的齿轮偏心块在启动和停机时，通过齿轮相位变换器调节各齿轮偏心块之间的相对位置，使齿轮偏心块产生的竖向和水平向激振力相互抵消。本发明在液压振动锤启动或停止过程中调节偏心力矩，消除振动锤在启动或停机过程中的共振现象。
