Importing several lines in a txt file to a single case in R

I'm starting to analyze mikrotik devices on a network, an i'm importing the syslog files of mikrotik in R. Files containing structures like this:

I'm stucked because this data is imported in several rows (cases) of a tibble. ¿how can I merge or import all lines to one case (row) of a tibble?
