When the electric working machine is in a working state, the angle between the movable upright post 3 and the fixed upright post 2 is increased so as to meet the requirement of height stroke when different devices of the electric working machine change the power. During the non-operating state, if in the transportation, reduce the angle between activity stand 3 and the fixed post 2 to satisfy the road limit for height requirement, conveniently transport. The power replacing vehicle is convenient to move, can run to the position of the operation machine to be replaced, performs power replacing operation on the electric operation machine, enlarges the service range, has strong maneuverability, is economical and applicable, can eliminate the limitation of a fixed power replacing station, and is convenient to meet the various and complex power replacing requirements of the electric operation machine in working scenes such as a power replacing excavator, a power replacing bulldozer, a power replacing road roller, a power replacing electric slag earthmoving vehicle and the like. The derivation process of the beneficial effect is substantially similar to the derivation process of the beneficial effect of the battery swapping device, and therefore, the description is omitted here.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
