Detailed Description

The invention is described with reference to the accompanying drawings and examples.

As shown in fig. 1 to fig. 3, the utility model discloses a small-size magnetic levitation micro-rail electric car suitable for contact rail receives electricity, including automobile body 1, driving system 4, guidance system 5, suspension system 8. After the maglev trolley stops, the roof of the car is lifted, the current-receiving pantograph 2 and the reflux pantograph 2 are in contact line contact with the contact net, and current flows into the storage battery 16 in the trolley from the transformer substation. The charging time is less than fifteen minutes, and after the charging is finished, the pantograph 2 and the reflux pantograph 2 fall off from the contact line simultaneously. The electric car is only powered by the electric quantity of the storage battery 16 to suspend, guide and drive the electric car in the running process of the electric car, and is also powered by the electric car for illumination, air conditioning, broadcasting, television and the like, the electric quantity of the storage battery 16 can be used for driving the electric car to go back and forth for several times, and the electric car runs for thirty-forty kilometers, so that the electric car has longer cruising ability.

As shown in fig. 1, the contact line of the contact network is made of a copper alloy material, and the surface of the pantograph 2 in contact with the contact line is made of a wear-resistant carbon sliding plate 17 material. The carbon slide 17 and the copper alloy wire have low resistance and high conductivity.

As shown in fig. 2, the lower insulator 25 of the pantograph 2 is mounted on the underframe 24 at one end and on the roof of the railway car 3 at the other end. The air bag device 23 and the pantograph device 26 are mounted on the underframe 24, the lower arm 20 is supported on the top of the air bag device 23, the lower arm 20 is hinged with the pantograph device 26, and the pantograph device 26 is a hydraulic or pneumatic mechanism. One end of the pull rod insulator 22 is hinged with the pantograph 26, and the other end is hinged with the lower guide rod 21. The upper arm 18 is connected with the lower arm 20 through a rotating shaft 19, and the extension section of the upper arm 18 is hinged with a lower guide rod 21. The bow 28 is hinged with the two upper arms 18, and a certain angle is formed between the two upper arms 18 to increase the span with the bow 28 and prevent the bow 28 from inclining. One end of the upper guide rod 29 is hinged with the upper arm 18, and the other end is hinged with the bow head 28. The slide plates 17 are mounted on the bow head 28, and the two slide plates 17 are connected by a connecting wire 24.

After the trolley arrives at the station, the hydraulic mechanism in the pantograph 26 pulls the lower arm 20 to swing upwards to drive the upper arm 18 to ascend, and simultaneously pulls the pull rod insulator 22 and the lower guide rod 21 to drive the upper arm 18 to rotate and ascend. After the upper arm 18 is lifted, the sliding plate 17 is lifted until the sliding plate contacts with the contact line on the contact net, the storage battery 16 in the automobile is charged, and the pantograph lifting action is completed. The upper guide rod 29 drives the bow head 28 to swing flexibly so that the sliding plate 29 is always in a horizontal state at different heights, and reliable contact with a contact line is guaranteed. The connecting line 24 between the two contact plates 29 ensures that the other contact plate 29 can be reliably powered after the contact plate 29 is in poor contact with the contact line. The upper arm 18, the lower arm 20, the lower guide rod 21 and the pull rod insulator 22 form a four-bar linkage mechanism, so that the sliding plate 29 can be ensured to receive power at different heights, and meanwhile, the structure also increases the stability of the bow 28 and the sliding plate 29.

After the battery 16 is charged, the hydraulic mechanism of the pantograph 26 drives the lower arm 20 to swing downwards, and simultaneously pulls the pull rod insulator 22 and the lower guide rod 21 to drive the upper arm 18 to rotate and descend. After the upper arm 18 descends, the sliding plate 29 also descends to be separated from contact with the contact line, and the pantograph descending action is completed. The air bag device 23 is used for buffering when the bow is descended.

It is right above the utility model discloses the detailed introduction of doing, this utility model utilizes new thinking to combine comparatively ripe technique to provide a small-size magnetic levitation micro rail trolley-bus suitable for contact net receives electricity like magnetic levitation technique, contact net technique etc. it will have more extensive application in the engineering.
