Abstract
A pivoting connection between a bucket and a padlock of a rope shovel, a pin assembly, and a rope shovel are disclosed. A pivoting connection includes a pin having a pin axis and extending through a bucket lug of the bucket and a pair of padlock lugs of the padlock; a flag having a pin end and a mounting end; a locking coupling coaxial with the pin axis and located in the pin end of the flag, wherein the locking coupling selectively couples the flag to the pin; and a slotted flag mount attached to the bucket including a vertical slot and a horizontal slot parallel to the pin axis; wherein the mounting end of the flag is received by the slotted flag mount such that the pin is constrained from rotating with respect to the bucket and from translating along the pin axis.

A pivoting connection between a bucket and a padlock of a rope shovel, comprising:
- a pin having a pin axis and extending through a bucket lug of the bucket and a pair of padlock lugs of the padlock;
- a flag having a pin end and a mounting end;
- a locking coupling coaxial with the pin axis and located in the pin end of the flag, wherein the locking coupling selectively couples the flag to the pin;
- and
- a slotted flag mount attached to the bucket including a vertical slot and a horizontal slot parallel to the pin axis,
- wherein the slotted flag mount comprises a first arm and a second arm, the first arm and the second arm spaced apart along a direction substantially parallel to the pin axis to provide the vertical slot, the first arm and the second arm including the horizontal slot;
- wherein the mounting end of the flag is received by the slotted flag mount such that the first arm is on one side of the flag and the second arm is on an opposite side of the flag, and the pin is constrained from rotating with respect to the bucket and from translating along the pin axis.
A pin assembly for a connection between a bucket and a padlock of a rope shovel, comprising:
- a pin having a pin axis and extending through a bucket lug of the bucket and a pair of padlock lugs of the padlock;
- a flag having a pin end and a mounting end;
- and
- a locking coupling coaxial with the pin axis and located in the pin end of the flag, wherein the locking coupling selectively couples the flag to the pin;
- wherein the mounting end of the flag abuts both a first arm and a second arm of a slotted flag mount attached to the bucket,
- wherein the first arm and the second arm are spaced apart along a mounting axis, and the mounting axis is substantially parallel to the pin axis.
A rope shovel, comprising:
- a bucket having a bucket lug and a slotted flag mount including a vertical slot and a horizontal slot, the vertical slot provided by a pair of arms;
- a padlock having a pair of padlock lugs;
- a pin having a pin axis and extending through the bucket lug and the pair of padlock lugs;
- a flag having a mounting end and a pin end including a first substantially cylindrical protrusion extending from a first side of the flag and a second substantially cylindrical protrusion extending from a second side of the flag opposite the first side;
- and
- a locking coupling coaxial with the pin axis and located in the pin end of the flag, wherein the locking coupling selectively couples the flag to the pin;
- wherein the mounting end of the flag is received by the slotted flag mount such that the pin is constrained from rotating with respect to the bucket and from translating along the pin axis, and
- wherein the arms constrain movement of the flag in a direction along the pin axis.
