Electrically-driven vibratory hammer
The invention discloses an electrically-driven vibratory hammer which comprises a vibration exciter and a vibration damper of a hanging bracket, motors are installed on frame plates on the left side and the right side of the hanging bracket and are vertically arranged, and the motors transmit power to a power input shaft of the vibration exciter through flexible couplings. The power input shaft transmits power to a transmission gear in the vibration exciter through a bevel gear set, and the transmission gear drives an eccentric block gear to rotate to generate excitation force. The motor is a fixed-frequency motor or a variable-frequency motor or a combination of a motor and a variable-speed motor; the shock absorber achieves shock absorption through different number combinations of rubber shock absorption blocks installed on the shock absorber. According to the invention, combined rubber is adopted for vibration reduction, noise is low, two-stage vibration reduction and a flexible coupling are adopted, so that the requirement for vibration resistance of the motor is greatly reduced, the manufacturing cost of the motor is reduced, high-frequency vibration like a hydraulic vibration hammer can be realized, construction under wider geological conditions can be covered, and compared with the hydraulic vibration hammer, the hydraulic vibration hammer has a greater cost advantage.
本发明公开了一种电驱振动锤，包括连接激振器和吊架的减振器，电机安装在吊架的左右两侧架板上并竖向设置，电机通过挠性联轴器将动力传递到激振器的动力输入轴，动力输入轴通过带圆锥齿轮组将动力传递到激振器内的传动齿轮上，传动齿轮带动偏心块齿轮旋转产生激振力；电机是定频电机或变频电机或电机+变速机的组合；减振器通过安装在减振器上不同数量组合的橡胶减振块实现减振。本发明采用组合橡胶减振噪音小，二级减振和挠性联轴器使得电机耐振性能要求大幅降低，降低电机制造成本，可实现像液压振动锤一样的高频振动，覆盖更为广阔的地质条件施工，相较液压振动锤有更大的成本优势。
