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 damaged and stops between the two iron tower ends, the self-propelled vehicle is damaged is avoided. The self-propelled vehicle does not need to be manually moved from the overhead ground wire to a stagnation position for auxiliary operation, is time-saving and labor-saving in operation, is safer, and is beneficial to application and popularization of the self-propelled vehicle.

    本发明提供了一种可中途返回的自走车,属于电力输送的技术领域。本发明通过在主支架上设置升降组件、推移组件以及解锁组件,可分别实现对驱动轮组件中的双滚轮的一端的翘起,对架空地线维持夹紧以及对双滚轮上的自锁结构的解锁,不仅能适当减小摩擦力,还能防止摩擦力过度减小导致返回过程中溜滑而导致的安全问题,另外,还消除了自锁结构对滚轮单向转动的限制,使得滚轮能反向旋转,从而便于操作者将自走车反向拉回,防止了在自走车的行走驱动电动机损坏而停在两铁塔端之间时,无需人工从架空地线上移动至停滞处进行辅助操作,操作省时省力,更加安全,利于自走车的运用和推广。
