PILE-DRIVING DEVICE FOR DRIVING OF PILES INTO THE GROUND Russian patent published in 2016 - IPC E02D7/18 

FIELD: construction.

SUBSTANCE: invention relates to construction, namely to devices for driving of piles, steel sections and other elongated objects into the ground. Pile-driving device is intended for driving of piles, steel sections and other elongated objects into the ground, the said pile-driving device includes a housing attachable to a tool with mechanical drive, vibration device attached to the housing by means of damping elastic gaskets, and the movable clamping grips adjustable relative to said vibration device for clamping the object subject to driving by at least a side clamp. Clamping elements in clamping grips can come together and move apart by means of control device, such as the hydraulic cylinder. To maintain mutual symmetry of clamping grips during their movement, clamping grips essentially comprise the levers, which are rigidly fixed at the location of swivels of clamping grips. Said levers are directed so that the ends of the levers are located next to each other and remain essentially next to each other in turns of clamping grips. Ends of said levers are connected to each other by means of the short lever having a hinged support.

EFFECT: technical result consists in provision of symmetrical arrangement of drive element relative to the grips to transmit equal load on the grips.
