Abstract
A concrete removing apparatus comprises a claw, a cleaving blade, and a bracket. The claw generally has a lower portion, a back portion, and an upper portion. The lower portion generally has a bottom surface, a sloped top surface, and extends forward from the back portion. The upper portion generally extends forward from the back portion partially overhanging the bottom portion and forming a locking notch defined by a front edge of the back portion, a bottom surface of the upper portion, and the top surface of the bottom portion. The cleaving blade is generally attached to a rear surface of the back portion of the claw. The bracket is generally mounted on a top surface of the upper portion of the claw and configured to pivotally connect the bracket to an arm and a hydraulic cylinder of a construction machine.
Claims13
A concrete removing apparatus comprising:
- a claw having a lower portion, a back portion, and an upper portion, wherein the claw comprises a plurality of ribs and two of the ribs form sides of the claw, the lower portion has a bottom surface, a sloped top surface, and extends forward from the back portion, the upper portion extends forward from the back portion partially overhanging the lower portion and forming a locking notch defined by a front edge of the back portion, a bottom edge of the upper portion, and the sloped top surface of the lower portion;
- a cleaving blade attached to a rear surface of the back portion of the claw, wherein the cleaving blade is attached at a lower rear surface of the back portion of the claw, extends orthogonally from the rear surface of the back portion of the claw, is supported on a first side by a section of steel plate welded at an angle between the first side of the cleaving blade and the rear surface of the back portion of the claw, and is supported on a second side by a triangular feature of each of the plurality of ribs;
- and
- a bracket mounted on a top surface of the upper portion of the claw and configured to pivotally connect the bracket to an arm and a hydraulic cylinder of a construction machine.
A method of removing pavement comprising:
- mounting a concrete removing apparatus to a construction machine, wherein said concrete removing apparatus comprises (i) a claw having a lower portion, a back portion, and an upper portion, wherein the claw comprises a plurality of ribs and two of the ribs form sides of the claw, the lower portion has a bottom surface, a sloped top surface, and extends forward from the back portion, the upper portion extends forward from the back portion partially overhanging the lower portion and forming a locking notch defined by a front edge of the back portion, a bottom edge of the upper portion, and the sloped top surface of the lower portion, (ii) a cleaving blade attached to a rear surface of the back portion of the claw, wherein the cleaving blade is attached at a lower rear surface of the back portion of the claw, extends orthogonally from the rear surface of the back portion of the claw, is supported on a first side by a section of steel plate welded at an angle between the first side of the cleaving blade and the rear surface of the back portion of the claw, and is supported on a second side by a triangular feature of each of the plurality of ribs, and (iii) a bracket mounted on a top surface of the upper portion of the claw and configured to pivotally connect the bracket to an arm and a hydraulic cylinder of the construction machine;
- breaking up the pavement into a number of sections using the cleaving blade of said concrete removing apparatus;
- sliding said lower portion of said claw of said concrete removing apparatus under a section of pavement of the number of sections of the pavement;
- lifting the section of pavement on the lower portion of the claw of the concrete removing apparatus;
- and
- placing the section of pavement on the lower portion of the claw into a truck.
