Single pole moving and swinging type public transportation trolley bus pantograph

Abstract

The invention relates to a single pole moving and swinging type public transportation trolley bus pantograph in the technical field of transportation; in the invention, the power output end of a swinging driving device is connected with a guide rail bracket which is hinged with and supported on a chassis; the chassis is provided with a pantograph top bar and a moving pantograph driving device; the pantograph top bar, under the effect of the moving pantograph driving device, can move in the transverse and lateral directions vertical to the driving direction of the public transportation trolley bus to extend out of the bus roof; bi-polar pantograph bodiesare respectively supported at the lower part of the pantograph top bar by an insulator; the bi-polar pantograph bodies are mutually insulated, thus forming a double power receiving body, the guide rail bracket and the moving pantograph driving device; the pantograph top bar, under the effect of the swinging and driving device, can swing and lift; as a result, the bi-polar pantograph bodies can respectively approach and closely contact the double conductors 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 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 [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 ...

AI Technical Summary

Problems solved by technology

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
