摘要
In the present invention, disclose a kind of equipment, the axis for being parallel to trolleybus for positioning trolley-bus collector item (3), wherein the equipment executes this positioning, is placed in frame (1) in cylinder (4) and turntable (5) is installed on trolleybus frame (1). Cylinder (4) is by two coaxial connections cylinder (41,42), in the front of a period of time, the piston (41) of first cylinder (410) passes through the piston (42) of second cylinder (420) in pipeline and following space (P1), so that the conduit is connected to compressed air source (P. Two spaces, in the first cylinder of space (41) of the second cylinder (42) and piston (420) below, piston (410) is equipped with outlet and leads to atmosphere.
