Abstract
A machine for driving posts, drills, large spikes, and the like work pieces into the ground, pavements, or wall structures. The machine comprises an elongated tower, a carriage, a hammer, a combination of an elongated two-way cylinder and a pulley system, at least one control valve box, a plurality of hydraulic pressurized lines, a plurality of hydraulic conduits, and a plurality of fasteners. The tower has two parallel rails for the hammer to slide upward, and then downward so as to exert a force upon the work piece toward a work surface. The machine may further include two two-way cylinders, a hammer guide, constraining springs and an interchangeable plate.
Claims12
A machine for driving posts, drills, large spikes, and like work pieces into the ground, pavements, or wall structures comprising:
- an elongated tower including an upper end, a lower end, and two parallel rails,
- said lower end of said tower is adapted for resting on a work surface,
- each of said rails having a channel parallel to each of corresponding said rails facing one another,
- a carriage including a first end and a second end,
- said first end of said carriage is adapted for attaching to hydraulic means for raising and lowering said tower,
- said second end of said carriage is adapted for attaching to said tower;
- means for attaching said carriage to said tower;
- a hammer having a top side, a bottom side, a first side, and a second side,
- said bottom side of said hammer is adapted for attaching with the work piece, and has sufficient rigidity and strength to exert a sufficient downward force on the work piece,
- said first and second sides of said hammer are adapted to slide upward and downward within said channels of said rails,
- wherein said hammer is dimensioned and configured to fit within said rails;
- hydraulic means for raising and lowering said hammer having a first end and a second end,
- wherein said hydraulic means for raising and lowering said hammer is adapted for attaching to said tower;
- wherein said hydraulic means for raising and lowering said hammer reciprocates between a first position with said hydraulic means for raising and lowering said hammer being closest to said lower end of said tower, and a second position with said hydraulic means for raising and lowering said hammer being farthest from said lower end of said tower;
- means for transporting hydraulic fluid is adapted for connecting securely to said hydraulic means for raising and lowering said hammer and to a hydraulic pressurized system of the hydraulic means for raising and lowering said tower;
- and
- means for controlling flow of hydraulic fluid is adapted for connecting securely to said means for transporting hydraulic fluid and to the hydraulic pressurized system of the hydraulic means for raising and lowering said tower.
