The invention discloses a sliding contact line connecting structure for rotary power supply of a tower crane in the technical field of sliding contact lines, which comprises a tower crane movable part and a tower crane fixed part which are rotatably connected, and a sliding contact line structure is arranged between the tower crane movable part and the tower crane fixed part; the sliding contact line structure comprises a current collector and a bus duct of a circular ring structure, and multiple sets of bus ducts are sequentially connected end to end to form a closed loop structure. According to the invention, the sliding contact line is transformed into an arc-shaped closed-loop structure and is applied to the tower crane, and the sliding contact line of the arc-shaped closed-loop structure can prevent wires and cables from being twisted off when the tower crane works in a rotating manner; and the sudden danger of tower crane power failure caused by sudden breakage due to twisting off of wires and cables is prevented.
Description
technical field [0001] The invention relates to the technical field of trolley lines, in particular to a trolley line connection structure for rotating power supply of a tower crane. Background technique [0002] Due to the movement, the mobile device needs to constantly change its position. In each different position, the mobile device must be able to obtain power at any time, otherwise it cannot continue to move. At this time, the trolley line came into being, and several conductors were laid in parallel along the running track of the mobile equipment, and the power was connected. On the mobile equipment, a current collector that can take electricity from the conductor is installed. In this way, when the equipment moves, the collector operates synchronously with the equipment, and obtains power from the conductor at any time to supply the equipment, so that the equipment can continue to move. [0003] Tower cranes are important equipment for construction and hoisting ope...
