Portable racking tool for electric equipment replacement
View Patent ↗An electrical device removal tool, such as for circuit breakers, that is lightweight, portable, and rugged for providing electrically operated controlled insertion and removal of electrical equipment by an operator from a remote location using a coupling device for engagement with the electrical equipment housing.
1. A portable racking tool for removing or installing electrical equipment surrounded by a metal surface, the racking tool comprising:
a motor mount plate for supporting a motor, the motor mount plate including an upper support and a lower support extending from the motor mount plate for aligning the racking tool against the metal surface;
a magnet mount bracket extending from the motor mount plate and supporting a magnet movable relative to the magnet mount bracket to engage the racking tool to the metal surface;
a handle coupled to the movable magnet, the handle movable relative to the magnet mount bracket for positioning the magnet between an extended position, to position the magnet against the metal surface surrounding the electrical equipment for engagement thereto, and a retracted position, to retract the magnet from the metal surface surrounding the electrical equipment to disengage the racking tool from the metal surface surrounding the electrical equipment;
a rotatable output shaft operably connected to the motor and disposed between the upper and lower supports, the output shaft configured to rotate a coupling to remove or install the electrical equipment while an operator is remote to the portable racking tool; and
a motor control housing secured to the motor mount plate, wherein the motor control housing includes a controller for controlling the motor to facilitate the removal or installation of the electrical equipment.
2. The portable racking tool of claim 1 , wherein the motor is disposed on a first side of the motor mount plate and the output shaft extends through the motor mount plate to a second side of the motor mount plate.
3. The portable racking tool of claim 1 , further comprising a handle for carrying the portable racking tool.
4. The portable racking tool of claim 1 , wherein the magnet is a non-electric magnet.
5. The portable racking tool of claim 1 , wherein the upper support member is disposed above the output shaft and the lower support member is disposed below the output shaft.
6. The portable racking tool of claim 1 , further comprising a gearbox disposed on the motor mount plate.
7. The portable racking tool of claim 1 , further comprising a remote operated switch for providing control to the motor.
8. The portable racking tool of claim 1 , wherein the upper and lower support members extend perpendicularly from the motor mount plate.
9. The portable racking tool of claim 1 , wherein the magnet is rotatably extendible to contact and secure to the metal surface.
10. The portable racking tool of claim 1 , wherein the output shaft is secured to a torque limiting clutch disposed on the motor mount plate.
