Pulling grip assembly
A pulling grip assembly and methods, systems, and apparatuses for constructing the pulling grip assembly are disclosed. The pulling grip assembly can include a pulling grip. The pulling grip can include an elongated body portion and a lug portion. The lug portion can include a blind hole for receiving an assembly including a hollow fastening member and a pulling cable retained within the hollow fastening member.
1. A pulling grip assembly comprising:
a pulling grip comprising
an elongated body portion, and
a lug portion comprising a blind hole, wherein the blind hole comprises internal threads progressing from a first end of the blind hole to a second end of the blind hole proximate the elongated body portion, and wherein at least a portion of the internal threads located proximate the second end of the blind hole extend less into the lug portion than at least a portion of the internal threads located proximate the first end of the blind hole in order to lock a hollow fastening member within the blind hole; and
the hollow fastening member defining an opening for receiving at least a portion of a pulling cable, wherein the hollow fastening member has a diameter smaller than a diameter of the lug portion of the pulling grip and a length that is shorter than a length of the blind hole of the lug portion, wherein the hollow fastening member comprises external threads, and wherein at least a portion of the external threads of the hollow fastening member bind with at least the portion of the internal threads located proximate the second end of the blind hole that extend less into the lug portion to lock the hollow fastening member completely within the blind hole such that unscrewing the hollow fastening member from the blind hole would damage at least a portion of the lug portion.
2. The pulling grip assembly of claim 1 , further comprising at least the portion of the pulling cable retained within the hollow fastening member.
3. The pulling grip assembly of claim 2 , wherein at least the portion of the pulling cable is retained within the hollow fastening member by a stop that is secured to an end of at least the portion of the pulling cable once the end of at least the portion of the pulling cable has passed through and is out of the opening defined by the hollow fastening member.
4. The pulling grip assembly of claim 3 , wherein the stop comprises a shank including a ball-shaped portion that has a diameter larger than a diameter of the opening defined by the hollow fastening member.
5. The pulling grip assembly of claim 1 , wherein the hollow fastening member comprises a plurality of slot screw drives.
6. The pulling grip assembly of claim 1 , wherein the hollow fastening member comprises a plurality of slanted slot screw drives.
7. The pulling grip assembly of claim 2 , wherein the pulling cable is able to twist axially when at least the portion of the pulling cable is retained within the opening of the hollow fastening member.
