After the driving assembly 1200 of the barrier gate movement 1000 is used for a period of time, the oil leakage phenomenon is easy to occur. Through research and experiments of the inventor, it is found that the reason for the oil leakage is that the oil of the driving assembly 1200 is disposed at the speed reducer 1220, when the driving motor 1210 is disposed vertically, the driving motor 1210 and the speed reducer 1220 are connected in a vertical direction, and the oil is easily leaked from the connection of the driving motor 1210 and the speed reducer 1220 by gravity. The output end of the driving motor 1210 is connected with the input end of the speed reducer 1220 in the horizontal direction, so that the oil of the driving assembly 1200 is not easy to leak from the joint of the output end of the driving motor 1210 and the input end of the speed reducer 1220, and the problem of oil leakage of the driving assembly 1200 of the barrier gate movement 1000 is solved.
