Group by consecutive index numbers

Here is one way:

from more_itertools import consecutive_groups
final=pd.concat([df.loc[i].reset_index(drop=True) 
                    for i in consecutive_groups(df.index)],axis=1)
final.columns=range(len(final.columns))
print(final)

              0             1
0  19218.965703  19279.216956
1  19247.621650  19330.087371
