Abstract
Aspects of the present disclosure related to lifting apparatuses and methods for attaching and lifting a load, including for example a lifting apparatus that includes an outer sleeve with first and second openings, an inner unit that has a chamber, a first shear pin, a second shear pin, and an actuation device along with a bar that is positioned within and movable within a track. The bar may also include a projection sized and shaped to engage with a guide in a surface of the outer sleeve. In an unlocked position the first and second shear pins may be disengaged from the first and second openings in the outer sleeve such that the outer sleeve may move relative to the inner unit.
Claims28
A lifting apparatus comprising:
- an outer sleeve having a first opening in a first side of the outer sleeve and a second opening in a second side of the outer sleeve;
- an inner unit further comprising:
- a chamber;
- a first shear pin;
- a second shear pin;
- an actuation device coupled to the first and second shear pins for actuating the first and second shear pins from an extended to a retracted position;
- and
- a bar positioned within and movable within a track, the bar further comprising a projection sized and shaped to engage with a slotted guide in a surface of the outer sleeve, wherein in an unlocked position in which the first and second shear pins are disengaged from the first and second openings in the outer sleeve, the outer sleeve may move relative to the inner unit.
A lifting system comprising:
- a first lifting apparatus comprising:
- a first outer sleeve having a first opening in a side of the first outer sleeve;
- a first inner unit having a first chamber, a first shear pin, a first actuation device coupled to the first shear pin for actuating the first shear pin from a locked to an unlocked position, and a first grip for coupling to a first connector of a load, wherein in the unlocked position the first shear pin is disengaged from the opening in the first outer sleeve such that the first outer sleeve may move relative to the first inner unit;
- a second lifting apparatus comprising
- a second outer sleeve having a second opening in a side of the second outer sleeve;
- a second inner unit having a second chamber, a second shear pin, a second actuation device coupled to the second shear pin for actuating the second shear pin from a locked to an unlocked position, and a second grip for coupling to a second connector of a load, wherein in the unlocked position the second shear pin is disengaged from the opening in the second outer sleeve such that the second outer sleeve may move relative to the second inner unit.
A method for attaching and lifting a load comprising:
- lowering a lifting system comprising a lifting apparatus onto a load;
- positioning an inner unit of the lifting apparatus onto the load such that the inner unit is blocked from moving further in a downward direction;
- continuing to lower an outer sleeve of the lifting system as the inner unit is retained in place by the load;
- automatically securing a grip of the lifting apparatus to a connector of the load;
- automatically actuating a shear pin from a released position to a locked position in which the shear pin projects into an opening in the outer sleeve of the lifting apparatus for securing the grip of the lifting apparatus to the connector of the load;
- and
- lifting the load by lifting the lifting system.
A method of detaching a lifting apparatus from a load:
- positioning the load on a surface;
- actuating a shear pin of the lifting apparatus from a locked position in which the shear pin projects into an opening in an outer sleeve of the lifting apparatus, to an unlocked position in which the shear pin does not project into the opening in the outer sleeve of the lifting apparatus;
- and
- disengaging a grip of the lifting apparatus from a connector of the load by lifting the lifting apparatus in a vertical direction.
A method for attaching and lifting a load comprising:
- providing a lifting system including a lifting apparatus, the lifting apparatus comprising:
- an outer sleeve having an opening in a side of the outer sleeve;
- a inner unit having a chamber, a shear pin, an actuation device coupled to the shear pin for actuating the shear pin from a locked to an unlocked position, and a grip for coupling to a connector of a load, wherein in the unlocked position the shear pin is disengaged from the opening in the outer sleeve such that the outer sleeve may move relative to the inner unit;
- lowering the lifting system onto the load;
- positioning the inner unit of the lifting apparatus onto the load such that the inner unit is blocked from moving further in a downward direction;
- continuing to lower the outer sleeve of the lifting apparatus as the inner unit is retained in place by the load;
- automatically securing the grip of the lifting apparatus to the connector of the load via downward movement of the outer sleeve as the inner unit is retained in place by the load;
- automatically actuating a shear pin from a released position to a locked position in which the shear pin projects into the opening in the outer sleeve of the lifting apparatus for securing the grip of the lifting apparatus to the connector of the load;
- and
- lifting the load by lifting the lifting system.
A lifting apparatus comprising:
- a locking body;
- an actuator;
- a lever;
- and
- a gear,
- wherein, the lever is coupled between the actuator and the gear such that the lever rotates in response to the actuation of the actuator, and
- wherein the gear is coupled between the locking body and the lever such that the locking body moves in response to the rotation of the lever,
- wherein the locking body is movable between a first position and a second position in response to the actuation of the actuator.
