PURPOSE: A hydraulic hammering device is provided to improve the reliability and service life of a hammering device and prevent the local deformation of components by adjusting contact speed with a detent into an allowable value. CONSTITUTION: A hydraulic hammering device comprises a main body(3). The main body comprises a cylinder(2). A hammering piston(1), which moves in a reciprocating motion by incompressible fluid in a hydraulic manner, is mounted inside the cylinder to be slidable. The motion of the hammering piston is controlled by a distributor(6) accepted inside a distribution box(7) mounted inside the main body. The distributor comprises an extension part(6c). The hydraulic hammering device comprises a brake chamber(32) and one or more correction paths(33). |
