Abstract

A hotstick assembly for installing and removing an electric power line conductor device includes an electrically insulated hotstick. A lead screw driver is attached to an upper portion of the electrically insulated hotstick, the lead screw driver includes a vertical slot extending through a tubular pipe for engaging a horizontal pin on the device for clamping and unclamping jaws on the device.

Claims

1. A hotstick assembly for installing and removing an electric power line conductor device comprising:

an electrically insulated hotstick;

a lead screw driver attached to an upper portion of the electrically insulated hotstick, the lead screw driver including a vertical slot extending through a tubular pipe for engaging a horizontal pin on a device for clamping and unclamping jaws on the device; and

a quick driver located adjacent a bottom portion of the electrically insulated hotstick, the quick driver includes a quick disconnect configured to engage a driver on a power driver drill, wherein the quick driver includes a tubular sleeve, a disc mounted inside the sleeve and the quick disconnect is located in the center of the disc and mounted to the disc.

2. The assembly of claim 1 including a horizontal slot located adjacent an upper portion of the vertical slot for engaging the horizontal pin on the device.

3. The assembly of claim 2 wherein the horizontal slot is arc shaped for preventing the hot stick assembly from separating from the device.

4. The assembly of claim 2 wherein the horizontal slot extends 45 degree relative to the vertical slot.

5. The assembly of claim 1 wherein the electrically insulated hotstick includes a fiberglass material.

6. The assembly of claim 1 wherein a portion of the interior of the electrically insulated hotstick includes foam.

7. The assembly of claim 1 wherein the disc is tapered at the bottom for allowing for the insertion of a quick release chuck for fastening to the quick disconnect.

8. The assembly of claim 7 wherein the quick disconnect includes a hex shaped cross-section band a groove for mating with a quick release chuck mechanism of a driver drill to prevent the drill driver from falling off the quick disconnect.

9. The assembly of claim 1 wherein the sleeve includes cutouts adjacent the bottom for allowing access to the quick release chuck to be pulled down for installation and removal of said chuck from quick disconnect.
