Pile driving hammer damping system and damping control method

Abstract

The invention provides a pile driving hammer damping system, comprising a damping device, a PLC, a hydraulic sensor, an oil tank, an oil pump, an oil pump controller, a hammer base and a helmet. The damping device is arranged in the hammer base, the damping device and the hammer base are arranged on the helmet in a sleeving mode, one end of the oil pump is connected with the damping device througha pipeline, the other end of the oil pump is connected with the oil tank through a pipeline, the hydraulic sensor is used for detecting the oil pressure of the damping device, the PLC is used for receiving a detection value of the hydraulic sensor and emitting a signal to the oil pump controller according to the detection value, and the oil pump controller is used for receiving the signal emittedby the PLC and controlling operation of the oil pump to enable hydraulic oil to be sucked or pumped into the oil pump to adjust the oil pressure of the damping device. According to the pile driving hammer damping system and a damping control method, the damping coefficient of the damping device can be adjusted in time to ensure that when the damping device is applied to different construction environments or striking force intensities are different, the damping device can keep a good damping effect.

Description

technical field [0001] The invention relates to the field of damping technology, in particular to a damping system and a damping control method for a piling hammer. Background technique [0002] Sea transport ships are constantly developing in the direction of large-scale. In order to meet the berthing and loading and unloading of large ships, the tonnage of newly-built wharves continues to increase. In the process of piling, alternate driving is often used so that it can act as a buffer between the piling hammer and the pile. During the piling process, the pile hammer hits the pile driver, and then hits the pile leg, and the pile leg will rebound upwards. Therefore, it is necessary to install a shock absorber to reduce the rebound force from the pile leg and reduce the adverse effects caused by system vibration. . Although the original damping device of piling hammer can effectively offset the rebound force of part of the pile legs, but when the piling construction enviro...
