DEEP WATER PILE DRIVER Russian patent published in 2013 - IPC E02D7/10 

FIELD: construction.

SUBSTANCE: driver comprises an anvil block, which is installed in an open frame and reciprocally moves by a hydraulic system, being in contact with water. A stem of a piston is placed in the piston cylinder and is attached by one end to the anvil block via a connecting mechanism. At the same time an outer source of hydraulic capacity is applied with a hydraulic chain on board. The connecting mechanism creates a connection between the piston stem and the anvil block as capable of transition, substantially, between a stiff lifting connection and substantially a soft connection for impact, preventing loss of stability with the piston stem, when the anvil block makes a strike in the extreme lower point. One version of realisation of the connecting mechanism includes a hollow body, which comprises opposite longitudinal slots, a rod sliding in the hollow body, which is connected in a sliding manner by a pin in one end of the opposite slots and rigidly connects by a pin in the other end of opposite slots to the anvil block, with a spring in the hollow body, creating a displacing action for pushing of the rod to the anvil block.

EFFECT: simplified operation, reduced dimensions of a system.
