Interlocking tip for demolition and construction equipment

摘要

A tip for demolition and construction equipment has a discrete base with at least one recess therein to accept a replaceable insert. The insert has a projection that fits within a mating socket within the base. A threaded bolt may extend through a common bore within the insert and base to secure the insert to the base. The tip may also include a second opposing insert which is held within a respective recess by a common bolt. Finally, each insert may have a key which interlocks within a keyway of the base recess to securely hold the insert within the base and to distribute forces created by a cutting operation over a greater area.

主权项

1. A tip for a jaw of a jaw set for demolition and construction equipment comprising:
a) a discrete base having:
i) a top side, a bottom side, a front side, and walls therebetween;ii) a generally planar mounting surface on the top side of the base adapted to be secured to the jaw;iii) a central portion, having a cutting edge integral therewith whereby the cutting edge is defined at the lowermost portion of the bottom side of the base at the intersection with the front side; andiv) a recess extending into each wall of the base, wherein the recess defines a recess upper side, an inner wall and a generally triangular recess contour;
1) wherein the recess upper side is a generally planar section and extends in a direction parallel to the mounting surface and;2) wherein the recess further includes a keyway extending within the generally planar portion of the upper side; and b) a pair of inserts, wherein each insert has:
i) a top side, a bottom side, a front side, and walls therebetween defining a generally triangular shape;ii) a cutting edge defined at the lowermost portion of the bottom side of the insert at the intersection with the front side; andiii) a profile which generally conforms to the recess contour, wherein the top side has generally planar sections and further includes a key protruding from a rearward end of the generally planar sections of the top side; and c) wherein an insert is secured within each recess such that the top side of the insert mates with the upper side of the recess and, wherein the keyway is engaged by the key and wherein the key is captured within the keyway thereby preventing movement of the top side of the insert relative to the upper side of the recess in a direction rearward from the front side of the base to provide an enhanced interlocking arrangement between the base and the insert, and wherein the front side of the base extends beyond the front side of each insert, such that the cutting edge of the base protrudes beyond the cutting edge of each insert.
