Cleat for joining chassis modules

摘要

A shearer mining machine generally includes a first chassis module, a second chassis module, one or more cleats, and means for securing each cleat on the first and second chassis modules. The first chassis module has a first mating surface and a first opening spaced from the first mating surface. The first opening is defined by a first wedge-shaped module wall positioned adjacent the first mating surface. The second chassis module has a second mating surface and a second opening spaced from the second mating surface. Each cleat includes a first projection, a second projection, and a bridge portion extending between the first projection and the second projection. The first projection is received by the first opening and includes a wedge-shaped cleat wall for engagement with the first wedge-shaped module wall. The means for securing apply a clamp force normal to the wedge-shaped cleat wall.

1. A shearer mining machine comprising:
a first chassis module having a first mating surface, a first outer surface, and a first opening spaced from the first mating surface and recessed with respect to the first outer surface, the first opening defined by a first wedge-shaped module wall positioned adjacent the first mating surface; a second chassis module having a second mating surface, a second outer surface, and a second opening spaced from the second mating surface and recessed with respect to the second outer surface; and a cleat including
a first projection received by the first opening and including a first wedge-shaped cleat wall for engagement with the first wedge-shaped module wall,a second projection received by the second opening, anda bridge portion extending between the first projection and the second projection, wherein upon insertion of the first and second projections into the first and second openings, the first wedge-shaped module wall cooperates with the first wedge-shaped cleat wall to clamp the first and second mating surfaces together.
