HYDRAULIC HAMMER Russian patent published in 2005 - IPC

Abstract RU 2265710 C1

FIELD: well drilling equipment, particularly fluid operated hammers.

SUBSTANCE: hydraulic hammer comprises housing, rod installed in the housing by spline which is restricted from falling out by bush. Bush is retained by spring. The rod is provided with sealing means. Spring-loaded hammer is arranged inside the housing. The hammer has through channel and sealing means. Crankshaft is connected to the rod by finger. Cross-over valve is connected to crankshaft by pin. The housing is provided with sub arranged in upper part thereof. Formed in outer hammer part is groove adapted to receive spline arranged on the housing. In initial position spring is released. In upper hammer position the valve is closed. After circulation restoring valve is restricted from opening by hydraulic forces and valve opening takes place only as a result of downward hammer movement, when α angle decreases. When hammer is installed in upper position the valve in closed and hydraulic impact takes place so that hammer applies impact action onto the rod. Time of valve opening and closing and hydraulic impact time are associated with hammer movement time. Hammer and cross-over valve are moved in time.

EFFECT: increased duration of closed valve state and, as a result, hammer impact amplitude and power.
