Double-wire powering trolleybus pantograph with damping spring barrel

Abstract

The double-wire powering trolleybus bow with damping spring barrel used in city public traffic includes bottom frame, lower arm rod, pull rod, upper arm rod, balance rod, head seat cross rod, cylinder, damping spring barrel, top cross rod, electrically conducting top sliding board, insulating seat, insulating rod and top spring. The six parts including bottom frame, lower arm rod, pull rod, upper arm rod, balance rod and head seat cross rod constitute two duplex planar quadric crank mechanisms with rods connected flexibly. The electrically conducting top sliding board is separated by the middle insulating rod into two current collectors fixed via the insulating seat on the top cross rod; and the top cross rod is connected flexibly to the head seat cross rod, with two ends being connected via the top spring. When the low arm rod is oscillated by the cylinder on the bottom frame via the damping spring barrel, the electrically conducting top sliding board will ascend or descend. The present invention has good contact performance, etc.

Description

technical field [0001] The invention relates to a trolley bus pantograph, in particular to a trolley bus double-wire receiving type pantograph with a spring damping cylinder, which belongs to the field of urban public transportation. Background technique [0002] At present, the trolley bus used for urban public transportation has the characteristics of low noise, no emission pollution, quick start and fast uphill, but due to the existence of overhead power supply contact wire network, roof collector pole and collector slipper, it makes the The tram cannot overtake the tram, and if there is an accident on the high-jump wire of the collector sliding shoe during driving, it will easily lead to traffic jams and affect the landscape above the city streets; the charging type trolleybus in the station area that uses large-capacity batteries or capacitors to store energy and stop for fast charging can Most of the overhead power supply catenary network is canceled, and only a specia...

AI Technical Summary

Problems solved by technology

[0005] The present invention has substantive features and significant progress, because the bow-top conductive slide plate is longer than the bow-top conductive slide plate of the pantograph used in electric locomotives and urban rail vehicles, and the bow-top conductive slide plate is separated and insulated in the middle part to become a double power receiving Therefore, it can contact double wires, and the double lines can receive current at the same time; change the trolley bus collector pole and groove-shaped collector slide shoes into pantograph and pantograph forms, and adopt a longer bow-top conductive slide structure, Cooperate with the trolley bus station area charging special catenary with widened double contact wire line distance, so that the current receiving part of the bow top of the pantograph will automatically lift and align with the trolleybus when driving at a low speed within a certain road range in the station area. It is convenient and unrestricted, thus solving the problem that the collector pole and the groove-shaped collector sliding shoe automatically rise up and align with the network when the trolleybus is running; The structure of the spring damping cylinder can adapt to the height difference of the double contact wires of the wire net, the change of the road surface and the vehicle, and the wind load, and the pantograph can also keep the tight contact between the bow and the net; When approaching the station, the bow is raised to charge the grid, and after leaving the station, it can drive without the overhead power supply catenary, so it not only greatly increases the flexibility and mobility, but also can mostly remove the overhead power supply catenary
