Double-wire pantograph type trolleybus collecting pole

Abstract

The double-wire bow collector type trolleybus collecting pole used in city public traffic includes bottom frame, collecting pole, pull rod, bow raising spring, balance rod, head seat cross rod, cylinder, top cross rod, electrically conducting top sliding board, insulating seat, insulating rod and top spring. The four parts including bottom frame, collecting pole, pull rod, balance rod and head seat cross rod constitute one parallelogram link rod mechanisms. 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 and the pantograph raising spring, the electrically conducting top sliding board will ascend or descend. The present invention has less network restriction to trolleybus, good contact performance, etc.

Description

technical field [0001] The invention relates to a collector pole of a trolleybus, in particular to a collector pole of a double-wire pantograph type trolleybus, 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 electric car cannot overtake the electric car, and if there is an accident where the collector slipper jumps off the wire during driving, it will easily lead to traffic jams and affect the landscape above the city streets; it uses large-capacity batteries or capacitors to store energy and stop for fast charging. Most of the overhead power supply catenary network can be canceled, and only a section of special charging catenary is reserved in the sta...

Problems solved by technology

"Although this utility model can be used for the automatic lifting and lowering of the collecting shoes of the collecting poles during the whole journey of the trolleybus, it is installed on the upper part of the collecting poles. The triangular wedge device with four sets of shafts, the electric pull rope device, and the collector shoe reset device with return spring have a complex structure and increase in weight; and the controllable lifting device of the trolleybus collector pole of other types is the same as the line entry condition. The trolley bus must run directly under the overhead power supply catenary network. If there is a slight deviation, it can be aligned with the line and enter the network. It is still impossible to connect the line to the grid within the range of the shoe guide bar, unless a huge line entry and shoe entry guide rod are set; the structure of the entry line, shoe entry guide rod and collector shoe in this utility model still makes the trolleybus suffer from overhead power supply contact wires. The constraints of the network, so the application range of this type of technology is greatly limited
