Description

Single pole translation type bus pantograph

technical field

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

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 intermediate stops. The trolleybus is separated from the traditional form of overhead power supply contact wire network and the driving constraints of the roof collector pole and collector slide shoe, so the collector slide shoe will not jump off the wire during driving and cause power failure and stoppage. Accidents such as traffic jams, because there is no overhead power supply catenary network, make the landscape above the city streets beautified, and at the same time, it can reflect the characteristics of trolleybus driving with low noise, no emission pollution, fast start and uphill.

After literature search, it was found that Chinese patent number: ZL200410015991.7, titled: bus tram scissor type bipolar pantograph. , placed on the top of the bus tram. When the bus tram enters the station, the cylinder stretches out, pushes the insulating connecting rod and drives the scissor four-bar mechanism to rise, and the electrodes are in close contact with the power contact wires to charge. Before the bus tram leaves the station, the cylinder shrinks, Pull the insulating connecting rod and drive the scissor-type four-bar mechanism to shrink, the electrodes are disconnected from the power supply contact wire, and the charging is completed. The application of the present invention can cancel the contact wire of the trolleybus, and use the fast charging technology as a supplement for the electric energy of the supercapacitor or battery bus , It can also be used for other electric vehicles and electric machinery that supplement electric energy by charging. 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 Not beautiful enough; moreover, two sets of symmetrical scissor-type four-bar mechanisms make the form and structure of the pantograph complicated, 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-mentioned problems, so this type of technology still has defects and its application range is still limited.
