Rank record from the base, supporting initial day-tripper? (9)

I believe the answer is:

detonator

I'm a little stuck... Click here to teach me more about this clue!

'rank record' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe there's a link between them I don't understand?

'from the base supporting initial day-tripper?' is the wordplay.
I cannot really see how this works, but
'from' could be 'o' (I've seen this in other clues) and 'o' is present in the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is present in the answer.
'base' could be 'e' (Euler's number - base of natural logarithms) and 'e' is located in the answer.
'day' could be 'd' (abbreviation for day) and 'd' is found within the answer.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for detonator that I've seen before include "small charge" , "means to cause explosion" , "Explosive initiator" , "Device for setting off a bomb" , "Part of bomb" .)
