Abstract
A portable racking tool for the installation and removal of electrical equipment, such as circuit breakers, is disclosed herein. Also disclosed is a method of using the portable racking tool. The portable racking tool can be lightweight and rugged for providing electrically operated controlled installation and removal of electrical equipment by an operator from a remote location using a coupling for engagement with the electrical equipment.
Claims18
A portable racking tool for removing or installing electrical equipment surrounded by a metal surface, wherein the portable racking tool comprises:
- a. a motor mount plate comprising:
- (i) a motor side comprising a motor side opening;
- (ii) an electrical equipment side comprising a first opening for engaging an electrical equipment handle attached to the electrical equipment, a second opening allowing viewing of an indicator on the electrical equipment, and a third opening allowing a coupling to pass through the motor mount plate to the electrical equipment;
- and
- (iii) a magnet side having at least one magnet side mounting hole, wherein the magnet side is disposed between the motor side and the electrical equipment side;
- b. a motor mounted to the motor mount plate and rotatably engaged with a gear box, wherein the gear box comprises a shaft housing;
- c. a rotatable shaft with a shaft keyway, wherein the rotatable shaft extends through the motor mount plate for receiving torque from the gear box, wherein the gear box is configured to rotate the rotatable shaft, wherein the rotatable shaft is engaged with a torque limiting clutch, and wherein the coupling is connected to the torque limiting clutch on one end of the coupling and capable of being connected to the electrical equipment on another end of the coupling;
- d. a gear box keyway disposed in the shaft housing;
- e. a key configured to engage the gear box keyway and the shaft keyway;
- f. a control bracket mounted to the motor;
- g. a motor control housing secured to the control bracket, wherein the motor control housing comprises:
- (i) an interface plug configured to receive signals and power from a remote switch operator;
- and
- (ii) a motor control circuit board connected to the interface plug configured to transmit the signals and power to the motor;
- h. an alignment tool engaged with the rotatable shaft through the motor mount plate, wherein the alignment tool is configured to rotate the coupling to align the coupling with the electrical equipment.
