I'm not a carpenter, but as a mechanic, if the hinge pin is doing that AND the deadbolt has a problem, I would expect a third problem. Maybe the door frame isn't square, or since it is the bottom hinge pin, maybe a threshold issue. The pin shouldn't be migrating, and if it did, the deadbolt shouldn't care. There should be three hinges on an entry door. Is the door warped?
Is this what you are working with? If so, you may be able to purchase lengths of wood trim and sandwich the edge of the fence between them. You can also get extruded aluminum in channel form and perhaps attach it with wire. You may even be able to put heavy duty shrink wrap over each sharp point.
Or maybe you have a different type of fence and this won't help haha. Let us know 🙂
Can you inquire with your local leadership about encroaching into the roadway? It really does seem like this would be your best option. Or reconstruction.
