Description

Single-rod mobile tilting bus pantograph

technical field

The invention relates to a power receiving device of a rechargeable public vehicle in the technical field of transportation, in particular to a single-rod mobile tilting bus trolley 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 the Chinese patent number: ZL03142211.X, the name is: double-wire receiving type trolleybus pantograph, the invention patent reads as "including: underframe, lower arm, pull rod, bow spring, upper arm , balance bar, bow head cross bar, cylinder, bow top cross bar, bow top conductive slide, insulating seat, insulating rod, bow head spring; chassis, lower arm, pull rod, upper arm, balance bar, bow seat Two double-connected planar four-bar linkages are formed between the six crossbars. The rods are connected flexibly. The conductive slide plate at the top of the bow is separated by an insulating rod in the middle to form a double current collector and is fixed on the crossbar at the top of the bow through an insulating seat. , the bow top cross bar and the bow head seat cross bar are movably connected in the middle, and the two ends are connected by the bow head spring. When the cylinder on the bottom frame and the bow spring make the lower arm swing, the bow top conductive slide plate will be raised and lowered. The invention has less constraints on the vehicle line network, good pantograph-catenary contact performance, safe and reliable work, and can enter and exit the network while the tram is running." Although this invention adopts the double-wire pantograph power receiving method with the liftable roof of the tram, its automatic lifting and lowering of the double-wire pair has less constraints on the network connection, and can be used for the double-wire power receiving and charging of the rechargeable trolleybus in the station area; but from its Technology "two double-linked planar four-bar linkages" and "when the cylinder on the bottom frame and the bow spring make the lower arm swing, the conductive slide plate on the top of the bow is raised and lowered", and "can be connected to the network while the tram is running It can be seen that the double-wire receiving type pantograph does lifting movement when it is working, and its bow-top conductive slide is powered from the special charging feeder network above the vehicle driving road in the overhead station area. Whether it is drawn from the electric pole on the sidewalk or the shed of the bus waiting station on the street, it still restricts the driving of other super-high vehicles such as some engineering vehicles and special transport vehicles, and the charging The station area of the trolleybus waiting station is not beautiful enough; moreover, the lower arm, tie rod, upper arm, balance bar, bow head cross bar, etc. constitute two double-connected planar four-bar linkages, making the form of the pantograph And the structure is complex, so this kind of technology has defects, and the scope of application is still limited.
