I've had simiar problems with a few of My Phals (and also some Oncs). I have 2 solutions. Either I place those plants on the edge of the shelves so that the spikes hang down freely, or I put the the in a hanging pot (without repotting, just put the pot in the pot) and hang the plant off the side of the shelves. I love having that sort of problem, it means I have happy orchids!!
