Queen after time inside conveyance (9)
I believe the answer is:
stretcher
'conveyance' is the definition.
(stretcher is a kind of conveyance)
'queen after time inside' is the wordplay.
'queen' becomes 'ER' (abbreviation for Elizabeth Regina).
'after' says to put letters next to each other.
'time inside' becomes 'stretch' (stretch of time in prison).
'er' after 'stretch' is 'STRETCHER'.
(Other definitions for stretcher that I've seen before include "Polish device" , "ambulance equipment?" , "one yawning?" , "Exaggeration" , "Means of carrying the wounded" .)
