The invention relates to the transport branch, namely to the devices of trolley-bus current-collectors, which make possible for trolley buses to make riding round of each other without the additional trolley-bus electric power line. A device for completion of riding round of trolley bus contains carrying trolley poles installed with possibility of contact with a detour device, which has a bypass electric power line and front and rear sliding contacts. In accordance with the invention, the detour device contains curvilinear paths, which are connected together by a lath. The front and rear sliding contacts are located at the ends of each of the paths. In the case in raised position the lower part of each path throughout entire length has U-shaped form in the section and surrounding electric power line is fixed along it. The upper parts of front and rear sliding contacts are concave, have arched form in the section. In the case to one of curvilinear paths an ear is fastened, which is freely located on the axle, which is rigidly fastened on the carrying pole. On the rear sliding contact a guide is fixed at an angle to the horizontal and vertical faces. The invention provides for riding round of one trolley bus by another without lowering the carrying trolley poles of both trolley buses and without need for the drivers of the trolley buses to leave their work places, which ensures the wide application of the express trolley buses, trolley buses of technical assistance, performance of required manoeuvres on high-speed and common route lines, and also in the trolley-bus depot. |
