Transmission and distribution line tap-connector removal tool
View Patent ↗The present invention provides an improved wedge connector removal tool for disconnecting a transmission or distribution line wedge tap connection and the methods of using such a tool. The tool may couple to a wedge connector around the transmission or distribution lines enabling a lineman's hands to be free from supporting the tool, and the wedge may be removed from the connection without the incorporation of powder charges.
1. A method for removing a wedge from a wedge sleeve thereby uncoupling a wedge connector from a first conductor and second conductor of a transmission or distribution line set, the method comprising:
a. mounting a wedge connector removal tool, including:
i. anchoring an attachment member to a surface of said wedge sleeve thereby supporting said removal tool,
ii. positioning a threaded nut under said wedge in a location opposite to said surface of said wedge sleeve; and
b. driving a bolt through said nut thereby applying a force operable to dislodge said wedge from said transmission or distribution lines and said wedge sleeve;
wherein said attachment member is attached to an elongated arm on a distal end of said wedge sleeve and said threaded nut is attached to the elongated arm on a proximal end of said wedge sleeve, wherein said elongated arm has a front surface, a rear surface, and a central axis.
2. The method of claim 1 , wherein said driving the bolt is advanced with a driving mechanism.
3. The method of claim 1 , wherein said central axis defines a plane of symmetry for said wedge connector removal tool.
4. The method of claim 1 , wherein said attachment member is provided in the form of an open-ended bracket having at least one protrusion with a position orthogonal to an interior surface of said elongated arm.
5. The method of claim 4 , wherein said attachment member and said elongated arm form a T-shape and position said protrusion perpendicular to said elongated arm front surface.
6. The method of claim 4 , wherein said protrusion has a substantially square geometry.
7. The method of claim 4 , wherein said removal tool includes two protrusions, each having a substantially curved geometry.
8. The method of claim 1 , wherein said threaded nut has a position that is centered with said central axis.
9. The method of claim 1 , wherein said surface of said wedge sleeve is a top surface having a large cross-section, and further includes a second bottom surface having a smaller cross-section, wherein said cross-section is substantially C-shape.
10. The method of claim 1 , wherein said force is applied to said bottom surface of said wedge and translates said wedge out of said sleeve.
11. The method of claim 1 , wherein said force is in a pressure ranging from 115 MPa to 200 MPa.
12. The method of claim 1 , wherein said bolt is further coupled to a ratcheting mechanism operable to advance said bolt.
