Embodiment Construction

[0027] figure 1 A mining machine 10 is shown including a prime mover (not shown) that propels the mining machine 10 . The frame 14 of the mining machine 10 is supported by a first track 18 and a second track 22 . Track shoes 26 are joined together to form first track 18 and second track 22 .

[0028] see figure 2 with Figure 4 , each track shoe 26 includes a first side or inner side 30 ( figure 2 ) and the second or outer side 34 ( Figure 4 ). In the illustrated configuration, when the mining machine 10 is propelled, the inner side 30 faces the frame 14 of the mining machine 10 and the outer side 34 faces away from the frame 14 and contacts the ground. Outer side 34 includes a substantially flat surface, allowing mining machine 10 to travel flat over the ground. Inboard side 30 includes a recessed area or track roller path 38 .

[0029] continue to see figure 2 , track shoe roller 38 extends over the entire width of inner side 30 of track shoe 26 . Track shoe r...

Abstract

A mining machine includes a frame having a guide rail, the guide rail having a central portion. The mining machine also includes a shoe having a recessed area that defines a roller path, the shoe further having a drive lug, wherein the central portion of the guide rail is configured to be disposed within the recessed area. The mining machine also includes a cutting tool coupled to the frame and positioned such that the cutting tool is configured to abrasively remove material from the drive lug as the drive lug passes by the cutting tool.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Application 62 / 947,109, filed December 12, 2019, the entire contents of which are incorporated herein by reference. technical field [0003] The present application relates to a mining machine and, more particularly, to a mining shovel utilizing roller tracks or tracks with lug shoes. Background technique [0004] When using a mining shovel, the weight and movement of the mining shovel from one location to another gradually compresses (eg, crushes) and wears down the roller rails or the plates of the track. As the roller rails compress and wear, the clearance between the drive lugs of the track shoes and the frame of the mining machine will decrease. Over time, the drive lugs will begin to inadvertently contact and interfere with the frame and / or lower roller hub, limiting useful life and / or requiring time-consuming maintenance. [0005] In order to prevent or sto...
