GROUND ENGAGING TOOL MANAGEMENT

A process, system and device for monitoring a ground engaging tool secured to earth working equipment that includes capturing an image of the ground engaging tool secured to the earth working equipment and subjected to wearing with a mobile device, determining a dimension of the ground engaging tool subject to wear, operating at least one processor and memory storing computer-executable instructions to calculate at least one result including the extent of wear experienced by the ground engaging tool and/or an estimate of when the ground engaging tool will reach a fully worn condition, and/or schedule when to replace the ground engaging tool.

SECUREMENT OF A WEAR MEMBER TO AN EXCAVATION IMPLEMENT
20170342688 · 2017-11-30 ·

A wear member attachment system for use with an excavation implement can include a connector that releasably secures a wear member to the excavation implement, the connector including an elongated housing and engagement members extendable and retractable relative to the housing. One engagement member can extend relative to the housing when another engagement member retracts relative to the housing, and vice versa. A method of releasably securing a wear member to an excavation implement can include rotating a engagement member of a connector from an extended position in which opposing slots in the engagement member are aligned with respective projections in the wear member, to a retracted position in which the slots are not aligned with the projections. The rotating step can include extending another engagement member of the connector as the first connector displaces from the extended position to the retracted position.

A wear member assembly may include a nose attachable to a bucket lip. The nose may include a rear portion having a first set of substantially planar surfaces including a first, second, and third subset of surfaces. The third subset of surfaces may be angled and positioned between the first subset of surfaces and the second subset of surfaces. The nose may also include a forward portion positioned forwardly adjacent to the rear portion, the forward portion having a second set of substantially planar surfaces including a fourth, fifth, and sixth subset of surfaces. The sixth set of surfaces may be angled and positioned between the first subset of surfaces and the second subset of surfaces. The wear member assembly may also include a wear member having a cavity comprising rear and forward bearing surfaces corresponding to the third and sixth subset of surfaces.

CONNECTOR SYSTEMS IN EARTH ENGAGING WEAR MEMBER ASSEMBLIES

A fastener includes an elongated shaft having a head at the end, the head comprising a lock fin extending radially outward from the shaft. The head includes an engagement cavity. The fastener further includes a cap having an engagement protrusion for insertion into the engagement cavity of the cap such that rotation of the cap causes corresponding rotation of the head, the cap further comprising a contact portion having a plurality of radially outward facing planar surfaces. The fastener further includes a rotation resisting element having inward facing planar surfaces that fit with the radially outward facing planar surfaces of the contact portion, the rotation resisting element further including an interference feature extending radially outward, the rotation resisting element being resilient so as to allow but resist rotation of the cap with respect to the rotation resisting element.

Lock for securing a wear member for earth working equipment

An articulated lock for securing a wear member to earth-working equipment includes a plurality of bodies interconnected for pivotal movement between an extended orientation with the bodies aligned and a retracted orientation with the bodies folded. The lock in the extended orientation can engage an opening of the wear member at an inner hold position to secure the wear member to the earth-working equipment or an outer release position. In the folded orientation the lock disengages from the opening of the wear member. Each body has a slot and a tab and, in the extended orientation, the tab of each body is received in the slot of the other body to limit separation of the bodies.

With a view to providing such an apparatus, the invention comprises a tooth adapter defining top and bottom walls and side walls, an adapter recess in one side, a retention means in the adapter recess, a bolt with a fastening inserted in the recess, a collar formed on the bolt of predetermined diameter, a tooth having side walls and defining a hollow chamber fitting over said adapter, a through tooth bolt opening formed in a tooth side wall of predetermined diameter, said tooth bolt opening being located to register with said adapter recess, when the tooth is positioned on the adapter.

In one version the diameter of the collar is slightly greater than the diameter of the tooth bolt opening, to create a locking effect.

Ground engaging tool wear and loss detection system and method

An example wear detection system receives first imaging data from one or more sensors associated with a work machine. The first imaging data comprises data related to at least one ground engaging tool (GET) of the work machine. The example system identifies a region of interest including data of the at least one GET within the first imaging data. Based on the identified region of interest, the example system controls a LiDAR sensor to capture second imaging data capturing the at least one GET that is of higher resolution than the first imaging data. The example system generates a three-dimensional point cloud of the at least one GET based on the second imaging data and determines a wear level or loss for the at least one GET based on the three-dimensional point cloud.

SYSTEM AND METHOD FOR DETECTING MISSING TOOTH IN MINING SHOVEL
20170287124 · 2017-10-05 ·

A method for detecting missing tooth in mining shovel, implemented using a processing device, includes receiving a pair of image frames from a camera disposed on a rope mine shovel configured to carry a mining load. A tooth line region corresponding to the pair of image frames is detected to generate a pair of tooth line regions based on a shovel template set. A difference image is determined based on the pair of image frames and the pair of tooth line regions. Further, a response map representative of possible tooth positions is determined based on the difference image using a tooth template matching technique. A tooth line is selected among a plurality of candidate tooth lines based on the response map. Further, a tooth condition is determined based on the tooth line and the difference image. The tooth condition is notified to an operator of the rope mine shovel.
