[dragon ball] why didn't kaioshin ask beerus for help?

I know that Beerus didn't exist at the time, but within the universe. Why didn't kaioshin tell Beerus about Majin Buu instead of Goku and Gohan? he could have contacted whis, to wake him up saying that this was an emergency.

Because he's the God of Destruction. It's entirely possible that Beerus would have deleted the Kais for waking him up, then left Buu alone. You don't try to aim a God of Destruction. Goku is the only person who has ever successfully done so, as far as we know.

Also, remember that Shin's actual plan was to stop Buu from waking up in the first place. Which would have actually been successful, had Vegeta not used the opportunity to settle a score.
