Technical Field

[0002] The contact network current collection system of the monorail straddle-type urban rail transit belongs to the rigid suspension current collection system. The rigid suspension system is relative to the flexible suspension system. The current-collecting conductor fixed in the rigid suspension system has considerable rigidity and basically does not deform under the action of the pantograph or collector shoe during the current collection process. The rigid contact network system in the Chongqing monorail straddle-type rail transit is different from the traditional overhead rigid contact network and the third rail current collection system of rail transit. It is a new form of contact network current collection for urban rail transit. It consists of aluminum busbars, contact wires and supporting insulators with corresponding rigidity, which are installed on the two sides of the track beam respectively to form a "positive" and "negative" power supply circuit to provide power for the train running on the track beam. The contact suspension is located in the middle of the PC beam and is completely enveloped by the car body. The contact current collection surface faces outward relative to the side of the track beam, and the pantograph faces inward relative to the side of the track beam to collect current by friction with the contact wire. It is arranged in a "Z" (up and down) shape along the line direction to make the pantograph wear evenly.
