Abstract
A wear liner retention device wear liner retention device comprises a shank structure, a nut structure, and an additional nut structure. The shank structure comprises a threaded region, an additional threaded, and an unthreaded region intervening between the threaded region and the additional threaded region. The nut structure is configured to threadably couple to the threaded region of the shank structure. The additional nut structure is configured to threadably couple to the additional threaded region of the shank structure. Related assemblies and methods are also described.
Claims16
An assembly comprising a wear liner and a wear liner retention device, the wear liner retention device comprising:
- a shank structure comprising:
- a threaded region;
- an additional threaded region;
- an unthreaded region intervening between the threaded region and the additional threaded region;
- and
- at least one opening extending completely through the threaded region and the unthreaded region and at least partially through the additional threaded region;
- a nut structure configured to threadably couple to the threaded region of the shank structure, the nut structure having a threaded opening extending completely therethrough;
- and
- an additional nut structure configured to threadably couple to the additional threaded region of the shank structure and to fit within an opening extending through the wear liner, the additional nut structure having an additional threaded opening extending completely therethrough.
An assembly, comprising:
- a vessel comprising a shell;
- a wear liner covering an internal surface of the shell of the vessel;
- and
- at least one retention device extending through and coupling the shell of the vessel and the wear liner, the at least one retention device comprising:
- a shank structure comprising:
- a threaded region extending into an opening in the wear liner;
- an additional threaded region extending into another opening in the shell aligned with the opening in the wear liner;
- and
- an opening extending completely through the threaded region and at least partially through the additional threaded region;
- an inner nut structure within the opening in the wear liner and threadably coupled to the threaded region of the shank structure along a threaded opening extending completely through the inner nut structure;
- and
- an outer nut structure overlying an exterior surface of the shell of the vessel and threadably coupled to the additional threaded region of the shank structure.
