A lifting device for a current collector comprises: a base plate (10); a four-bar linkage mechanism (2) capable of raising or lowering the current collector, wherein a frame of the four-bar linkage mechanism (2) is disposed on the base plate (10); a first driving member (3) capable of rotating a crank of the four-bar linkage mechanism (2) in a shoe-lowering direction; a first elastic member (1) having an elastic force for rotating the crank in a shoe-lifting direction, wherein one end of the first elastic member (1) is disposed on the base plate (10) and the other end is connected to the crank; a position-limiting member capable of maintaining the four-bar linkage mechanism (2) in a shoe-lowering position; a second elastic member (5) having an elastic force for locking the four-bar linkage mechanism (2) inside the position-limiting member, wherein one end of the second elastic member (5) is fixed, and the other end is connected to the position-limiting member; and a second driving member (4) capable of driving the position-limiting member to release the four-bar linkage mechanism (2). In the lifting device for a current collector, the first driving member (3), the second driving member (4), the first elastic member (1), the second elastic member (5), and the position-limiting member work together to lift or lower the four-bar linkage mechanism (2), so as to lift and lower the shoe of the current collector, thereby meeting requirements of an electrical device to lift or lower a shoe.
