Benefits of technology

The solution provides a safe, easy-to-use locking system that is compatible with older locking mechanisms, reducing downtime and worker safety risks by allowing the use of modern locking systems with existing support structures without the need for retrofitting, ensuring secure attachment of wear members.

Problems solved by technology

The teeth, as well as the adapters, wear over time and therefore need to be replaced frequently during operation.
Worker safety is also an important issue.
As a result, wedge-and-spool locks are difficult to remove and sometimes shatter during installation or removal, endangering the safety of nearby workers.
However, many of these systems require specific features in the wear members or support structures.

Embodiment Construction

[0033] Generally, the present invention provides for an insert that can be used in a passageway extending through a support structure to provide for a meansto lock a wear member to the support structure using a modern locking system. It is used with locking systems that lock the wear member to the support structure but which do not require special attachments in the support structure passageway. The insert is preferably used with older designed support structures having a passage extending through the support structure to generally align with at least one passage in matching old-style wear members. The insert may also be used with these older designed support structures and with newer-style wear members having a passage in communication or contiguous with the passage in the support structure or having two passages in the wear member, one extending through the upper leg of the wear member and one extending from the rearward end of the wear member in a generally longitudinal direction...

Abstract

The present invention is directed to an insert for use with ground engaging tools. It allows newer-type locking mechanisms to be used to lock wear members to older-styled support structures. The insert is comprised of an elongated body for insertion into a passage in the support structure. At one end is a faceplate for engaging the inner surface of the wear member. At the other end is preferably an attachment means for connecting to corresponding attachments on the inner surface of the opposing leg of the wear member. The faceplate has a recess for receiving the end of a lock pin used to lock the wear member or adapter to the support structure. Alternatively, a lock pin may abut against the rear end of the faceplate.

Description

FIELD OF THE INVENTION [0001] This invention relates to the field of locking and coupling mechanisms for retaining wear members on support structures and, preferably, for use with ground-engaging tools. BACKGROUND OF THE INVENTION [0002] Buckets on digging machines are generally equipped with replaceable ground-engaging teeth. These teeth attach to adapters or adapter bases, which indirectly attach the teeth to the bucket lip. The teeth, as well as the adapters, wear over time and therefore need to be replaced frequently during operation. As well, lock mechanisms that couple these together and / or to the base must be easy to use to minimize downtime of the equipment. [0003] Worker safety is also an important issue. Adapter locking mechanisms are often the older type commonly called wedge-and-spool. These locks are comprised of two pieces that are hammered into an opening in the wear member and the support structure on which the wear member is placed. Once hammered into place, they ar...
