Given the universal set $U=\mathbb{R}$, the non-empty set $A=\{x| \frac {x-2}{x-3a-1}<0\}$, $B=\{x| \frac {x-a^{2}-2}{x-a}<0\}$.  
(Ⅰ) When $a= \frac {1}{2}$, find $(\complement_{U}B) \cap A$;  
(Ⅱ) Let condition p: $x\in A$, condition q: $x\in B$. If p is a sufficient but not necessary condition for q, find the range of the real number $a$.
