Abstract
An electrically-driven vibratory hammer is provided, which has a power supply, is wirelessly controlled, can increase the vibration amplitude and can detect the data of the vibratory hammer in real time. Through the arrangement of storage batteries, workers can also directly work through the built-in storage batteries during construction in some remote areas, without laying additional lines, and the cost is reduced. Furthermore, a movable toothed plate previously driven by a hydraulic cylinder is changed into a clamping electric cylinder capable of directly working through the storage batteries, so that a pile body can be directly clamped without an external hydraulic pump station during working. Through the improvement, the workers can directly work without additionally laying basic equipment during construction in construction sites with incomplete facilities, the construction period is shortened, the construction cost is saved, intelligent control is achieved.
