Abstract
The present disclosure relates generally to systems and methods for sensing wear in machines designed to reduce or break-down material. More particularly, the present disclosure relates to systems and methods for sensing wear of reducing elements used by excavation machines such as surface excavation machines. The present disclosure relates to a wear sensing system including a multi-level wear sensor protection system. The multi-level wear sensor protection system includes a first level of protection, a second level of protection, and a third level of protection.
Claims4
A wear sensing system comprising:
- sensors;
- a multi-level wear sensor protection system, the multi-level wear sensor protection system including a first level of protection, a second level of protection, and a third level of protection;
- wherein the first level of protection includes an initial barrier layer, the initial barrier layer comprising a plurality of sheet segments;
- wherein the second level of protection includes a side-by-side arrangement of trays positioned behind the initial barrier layer, the trays are configured to absorb impacts that are transmitted through the initial barrier layer to prevent the impacts from impacting upon the sensors;
- and
- wherein the third level of protection includes a relief structure for accommodating impacts that are transmitted through both the initial barrier layer and the trays, the relief structure is positioned behind the trays for accommodating movement of the trays in response to an impact that passes through the initial barrier layer and the trays, the relief structure being an impact absorption structure that includes a base and legs configured to bend and flex while biasing the trays toward a sensing position.
