FIELD: drilling.
SUBSTANCE: invention relates to a method for detecting obstacles during the operation of a vibratory pile driver, to a corresponding vibratory pile driver, as well as to a working machine with a vibratory pile driver. A method for detecting obstacles during the operation of a vibratory pile driver, in which the signals of acceleration of the vibratory pile driver are recorded, differs in the stages at which the acceleration signals are analyzed. The analysis includes a comparison of negative and positive half-waves, and acceleration signals are recorded by at least one acceleration sensor on the vibratory pile driver and/or on the mast connected to the vibratory pile driver and/or the clogging product.
EFFECT: ensuring the detection of obstacles during the operation of the vibratory pile driver and the corresponding device for implementing a method by which more gentle operation is possible, providing a reliable warning system that automatically and timely warns the driver of the corresponding danger.
