Abstract

The mechanical-hydraulic double-acting drilling cylinder consists of a round shaft. Shape of the inner pipe supporting the inside of the tank Each round shaft and body consist of a group. Of the connected pipe-shaped section Together by a required threaded internal connection, the top and bottom pressure pistons are placed sliding inside the tank, which Will close the hydraulic chamber sealed above and Below, respectively, the longitudinal movement of the round shaft in conjunction with the gear will move the ball Top or side cylinder The bottom depends on the direction of movement of the round shaft.When one of the pistons is moved, the fluid pressure is generated in the joint hydraulic chamber and opposes the movement of the round shaft and the potential energy is generated. In the drilling line The gear is limited from protrusion until the round shaft reaches a specific point in the hull at the time when the overhang is released to the round shaft to crash. Quickly against the hammer surface with anvil in the body
