Abstract
A core catcher includes a catcher rod removably attachable to a core drill. The catcher rod is inserted through a pilot hole in a substrate from which a core is to be removed. A catching element is removably attachable such as by clamping the catching element to a distal end of the catcher rod on an underside of the substrate. A bearing may be disposed between the catching element and the substrate. When severed from the substrate, the core falls only a short distance along the catcher rod and comes to rest on the bearing and the catching element. Thus, the core is inhibited from falling to a floor or ground below the substrate. A bucket may also be supported on the distal end of the catcher rod in order to collect cutting fluid.
Claims22
A core catcher for catching a core after cutting the core from a substrate, the core catcher comprising:
- a catcher rod having a proximal end and a distal end;
- an attachment mechanism on the proximal end of the catcher rod configured for attaching the catcher rod to a core drill;
- a catching element removably attached to the catcher rod;
- wherein:
- the catcher rod has a length extending generally between the proximal end and the distal end, and a width extending in a transverse direction relative to the length;
- and
- the catching element has a dimension in the transverse direction that is greater than the width of the catcher rod when the catching element is removably attached to the catcher rod in a deployed condition.
A system for catching a core cut from a substrate during core drilling, the system comprising:
- a core catcher assembly including at least one catcher rod;
- an attachment mechanism on a proximal end of the catcher rod;
- and
- a catching element for retaining a core on the catcher rod, the catching element being of a removably attached to the catcher rod.
A method for catching a core, the method comprising:
- drilling a pilot hole in a substrate to be cut;
- inserting a catcher rod in the pilot hole;
- attaching a proximal end of the catcher rod to a drill;
- and
- removably attaching a catching element on a distal end of the catcher rod.
A core catcher for catching a core after cutting the core from a substrate, the core catcher comprising:
- a catcher rod having a proximal end and a distal end;
- an attachment mechanism on the proximal end of the catcher rod configured for attaching the catcher rod to a core drill;
- a catching element removably attached to the catcher rod;
- wherein:
- the catcher rod has a length extending generally between the proximal end and the distal end, and a width extending in a transverse direction relative to the length;
- the catching element has a dimension in the transverse direction that is greater than the width of the catcher rod when the catching element is in a deployed condition;
- and
- the catcher rod has structure defining a passageway extending into the proximal end and out through a duct in an outer surface of the catcher rod.
A system for catching a core cut from a substrate during core drilling, the system comprising:
- a core catcher assembly including at least one catcher rod;
- an attachment mechanism on a proximal end of the catcher rod;
- and
- a catching element comprising a clamping collar for retaining a core on the catcher rod, the catching element removably attachable to the catcher rod.
