Pile driving-in device
专利汇可以提供Pile driving-in device专利检索，专利查询，专利分析的服务。并且PURPOSE: To provide a pile driving-in device for having a high efficiency and less noise, by locating a vibration generating system, a shock absorber, and a pile holding blade at a device proper which forcibly comes up and down, being connected to an endless chain and being guided by a leader.
CONSTITUTION: An endless chain is attached at a coupling part 15, which protrudes from a device proper 8, and the device proper is forcibly pulled down along a leader 7 as a result of pulling the chain through the working of a hydraulic driving device of a hydraulic shovel truck. In the meantime, pressured oil is fed to a servo-valve 35, and simultaneously an amplified signal having a given vibration pattern is sent to a torque motor. And thus, a vibrating substance 2 and a cylindrical weight 32 vibrate vertically as they act on each other. At this time a upward impact is not given to the chain since the impact is absorbed by five rubber shock absorber 25. Only a downward impact is given to a pile P held between a stationary blade 3 and a moving blade 44.
