Single pole translational type public transportation trolley bus pantograph

Abstract

The invention relates to a single pole translational type public transportation trolley bus pantograph which receives power in the transverse and lateral direction in the technical field of transportation; in the invention, the power output end of a lift pantograph driving device for a chassis is connected with a support bar or a pantograph top bar; the lower ends of a plurality of support bars are hinged with the chassis, the upper ends thereof are respectively connected with the pantograph top bar; the bi-polar pantograph bodies are supported at the lower part of the pantograph top bar by an insulator, and are mutually insulated to form bi-polar pantograph bodies; a link mechanism is composed of the chassis, the support bar and the pantograph top bar; the link mechanism, under the effect of lift driving device for collector pantograph, can move in the transverse and lateral plane vertical to the driving direction of the public transportation trolley bus to facilitate the pantograph top bar to lift and move along with the pantograph bodies thereon; as a result, the bi-polar pantograph bodies can approach and closely contact the double feeding wires to receive power. The invention features simple structure, beautiful waiting lounge, no restrictions imposed on passing vehicles and safe and reliable operation.

Description

technical field [0001] The invention relates to a power receiving device of a rechargeable bus in the technical field of transportation, in particular to a single-rod translation bus pantograph that receives power laterally. Background technique [0002] At present, the bus or trolley bus using supercapacitor energy storage in the field of urban public transportation has entered commercial operation or trial operation, and its vehicle has a small amount of supercapacitor, so the vehicle is light in weight, flexible and fast, and only needs to use the terminal and Short-term fast supplementary charging when parking at some intermediate stops can drive uninterrupted on the entire operating line. Since this technology can mostly cancel the original trolleybus overhead power supply contact wire network or feeder wire network along the bus line, only a section of contact wire network dedicated to charging is reserved above the station area of ​​the terminal station and some inter...

Problems solved by technology

Although this invention adopts the pantograph power receiving method with the liftable roof of the tram, its automatic lifting and lowering of the two-wire pair has less constraints on the network connection, and can be used for the two-wire power receiving and charging of the rechargeable trolleybus in the station area; but from its technology and "The cylinder stretches out, pushes the insulating connecting rod and drives the scissor-type four-bar mechanism to rise. When the electrode supporting plate rises with the electrode support, the electrodes on the supporting plate are in close contact with the power contact wires." It can be known that the scissor-type bipolar pantograph Lifting movement during work, the electrode support plate and electrodes are powered from the special charging feeder network above the vehicle driving road in the overhead station area, due to the existence of the feeder wire Whether it is drawn out on the pole or through the billboard of the street bus waiting station, it still restricts the driving of other super-high vehicles such as some engineering vehicles and special transport vehicles, and the station area of ​​the charging bus and tram waiting station is therefore It is not beautiful enough; moreover, two sets of symmetrical scissor-type four-bar mechanisms complicate the form and structure of the pantograph, because there are multiple identical rods and connecting shafts in the scissor-type four-bar mechanisms

Other related technologies of the same kind: double-wire pantograph trolleybus collector poles and double-wire powered trolleybus pantographs also have the above problems, so this type of technology still has defects and its application range is still limited
