Bi-wiring itemizing swinging translational type public transportation trolley bus pantograph

Abstract

The invention relates to a bi-wiring itemizing swinging translational type public transportation trolley bus pantograph in the technical field of transportation, comprising a chassis, a lift pantograph driving device, conductive pantograph bodies, an insulator, support bars, a pantograph top bar, a pantograph top subsidiary bar, a pantograph pantograph subsidiary bar and a subsidiary bar connecting supporter; in the invention, on the chassis, the lift pantograph driving device is connected with the support bar; the upper end and lower end of a plurality of support bars are hinged with the chassis, the pantograph top subsidiary bar is hinged with the pantograph top bar, the two ends of subsidiary bar connecting supporter are respectively connected with the pantograph top bar and the pantograph top subsidiary bar; bi-polar pantograph bodies are supported at the lower part of the pantograph top bar and the pantograph top subsidiary bar; the chassis, the support bar and the pantograph top bar form a link mechanism; under the effect of the lift pantograph driving device, the link mechanism can move in the transverse and lateral plane vertical to the driving direction of the public transportation trolley bus, besides, the pantograph top subsidiary bar can swing in the same plane around the hinged end, as a result, the bi-polar pantograph bodies can approach and closely contact double feeding wires to receive power. The invention features extremely simple structure, beautiful waiting lounge, no restrictions imposed on passing vehicles.

Description

technical field [0001] The invention relates to a power receiving device for a rechargeable public transport vehicle in the technical field of transportation, in particular to a pantograph of a horizontal and lateral two-line split-type swing-translation bus tram. Background technique [0002] At present, buses, trams or trolleybuses that use supercapacitor energy storage in the field of urban public transportation have entered commercial operation or trial operation. They have a small number of supercapacitors onboard, so the vehicle has a lighter weight and is flexible and fast. It only needs to use the arrival terminal and Short-term rapid recharging when parking at some intermediate stops can enable uninterrupted driving on the full operating line. Because this technology can cancel most of the original trolleybus overhead power supply contact line network or feeder network along the bus line, only a section of contact line network dedicated for charging is left above th...

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
