The invention provides a self-propelled vehicle capable of returning midway, and belongs to the technical field of electric power transmission. According to the invention, the lifting assembly, the pushing assembly and the unlocking assembly are arranged on the main support, so that tilting of one end of each of double rollers in the driving wheel assembly, clamping maintaining of an overhead ground wire and unlocking of a self-locking structure on the double rollers can be realized, friction force can be properly reduced, and clamping of the overhead ground wire can be maintained. The safety problem caused by slipping in the returning process due to excessive reduction of friction force can be solved, in addition, limitation of a self-locking structure on one-way rotation of the rolling wheels is eliminated, the rolling wheels can rotate reversely, an operator can pull the self-propelled vehicle back reversely conveniently, and the situation that when a walking driving motor of the self-propelled vehicle is
