The invention relates to a bi-wiring itemizing swinging type public transportation trolley bus pantograph which receives power in the transverse and lateral direction, comprising a chassis, conductivepantograph bodies, an insulator, a guide rail bracket, a swinging and driving device, a pantograph top bar, a pantograph moving and driving device, a pantograph top subsidiary bar and a subsidiary bar connecting supporter; in the invention, on the chassis, the swinging and driving device is connected with the guide rail bracket, the guide rail bracket is hinged on and supported on the chassis, the chassis is provided with the pantograph top bar and the moving and driving device for collector pantograph; under the effect of the pantograph moving and driving device, the pantograph top bar movealong the guide rail bracket in the transverse and lateral directions to extend out of the bus roof; the pantograph top subsidiary bar is hinged with the pantograph top bar; the two ends of the subsidiary bar connecting supporter are respectively connected with the pantograph top bar and the pantograph top subsidiary bar; the bi-polar pantograph bodies are supported at the lower part of the pantograph top bar and the pantograph top subsidiary bar; under the effect of the swinging and driving device, the guide rail bracket, the pantograph top bar and the pantograph top subsidiary bar swing andlift; the pantograph top subsidiary bar can swing around a hinged end, as a result, the bi-polar pantograph bodies can move and lift and respectively approach and closely contact double feeding wiresto receive power. The invention features extremely simple structure, beautiful waiting lounge, no restrictions imposed on passing vehicles.
