Lateral current collector with double four-bar mechanisms connected in series

Abstract

The invention discloses a lateral current collector with double four-bar mechanisms connected in series. The lateral current collector comprises a base, a drive locking mechanism, a current collection sliding shoe, a sliding shoe base and a swing mechanism. The swing mechanism is connected between the base and the sliding shoe base. The drive locking mechanism is installed between the base and the bottom of the swing mechanism. The current collection sliding shoe is installed on the side, back on to the swing mechanism, of the sliding shoe base. The swing mechanism is formed by connecting the top four-bar mechanism and the bottom four-bar mechanism in series. The bottom four-bar mechanism is composed of a base, a main swing bar, the lower half part of an upper supporting bar and a lower connecting bar. The top four-bar mechanism is composed of the upper half part of the upper supporting bar, the sliding shoe base, an upper connecting bar and the upper half part of the lower connecting bar. A sliding shoe installation plate is arranged between the sliding shoe base and the current collection sliding shoe and connected with the sliding shoe base through a spherical hinge or a double-shaft deflection mechanism. The lateral current collector is simple and reasonable in structure and large in extension amplitude, and the current collection reliability of the lateral current collector can be guaranteed even when the lateral displacement and deflection amplitude of a train are large.

Description

technical field [0001] The invention relates to a current collector, in particular to a lateral current collector with a double four-bar linkage mechanism in series, which is suitable for use on the lines of monorail trains and conventional maglev trains in the elevated line traffic mode. Background technique [0002] The current collector is a current receiving device installed on the frame of the urban rail transit vehicle. Through the sliding contact between the sliding shoes on the current collector and the ground power supply rail, the ground electric energy is guided to the train. When the current receiver is working normally, under the action of the spring force, the current receiver swing rod and the current receiver sliding shoe are pressed to the power supply rail (the third rail), so that the current receiver sliding shoe is in contact with the power supply rail. [0003] Among the existing current collectors, a typical current collector (a lateral current collect...

Problems solved by technology

[0003] Among the existing current collectors, a typical current collector (a lateral current collector, patent number ZL201010557003.7) uses a single quadrilateral structure to realize the telescopic action of the sliding shoe. The disadvantage is that the structural layout is flexible. Low performance, unable to adapt to the system coordination requirements of the spatial structure layout under the large expansion and contraction size, adapt to the small expansion and expansion range, when the train has a large lateral displacement and deflection relative to the track, it is easy to cause the flow-absorbing shoe to jump and arc. It makes the train unsteady when receiving current, and the single quadrilateral structure is not suitable for the application under the working conditions requiring large stretching range
