Mobile catenary of electrified railway coal loading station

Abstract

The invention discloses a mobile catenary for an electrified railway coaling station. A left portal frame and a right portal frame stretch across lines on the two sides of a hopper bin; a left fixed busbar and a right fixed busbar are rigidly suspended below the middles of a left cross beam and a right cross beam; a left moving trolley is mounted on the left cross beam; a tension compensation trolley is mounted on the left moving trolley; a left mobile busbar is rigidly suspended below the tension compensation trolley; a right moving trolley is mounted on the right cross beam; a right mobile busbar is rigidly suspended below the right moving trolley; a mobile contact line is connected between the left mobile busbar and the right mobile busbar; a left electric push rod and a right electric push rod mounted at the front parts of the left cross beam and the right cross beam are respectively connected with the left moving trolley and the right moving trolley so as to drive the mobile contact line to move forwards and backwards in the direction parallel to the lines; the tension compensation trolley moves to provide tension for the mobile contact line or release the tension of the mobile contact line; and the left fixed busbar and the right fixed busbar are respectively connected with flexible contact lines on the outer sides of the left fixed busbar and the right fixed busbar. During coaling, the mobile contact line is moved away, and the mobile contact line is moved to a position above the railway so as to provide electricity for an electric locomotive when a train enters and leaves a coaling zone.

Description

Technical field [0001] The invention belongs to the technical field of rail transit rigid contact networks, and specifically relates to a mobile contact network for electrified railway coal loading stations. Background technique [0002] The electrified coal transportation railway needs to be equipped with a coal loading station, and the quantitative hopper bin and coal chute of the coal loading station are erected above the line, and the space above 6.5m on the track surface is occupied. The section about 9m long in the direction of the line cannot be erected. The flexible catenary system cannot use the train’s inertia to pass through the unpowered area. It is a common problem for electric locomotives to pass through the hopper when charged. Therefore, the only way to replace the internal combustion shunting locomotive or use double electric locomotives in this unpowered area To complete the double bow, it restricts the efficiency of the entire logistics chain. Summary of the i...

Problems solved by technology

[0002] The electrified coal transportation special railway needs to be equipped with a coal loading station, and the quantitative hopper bin and coal chute of the coal loading station are erected above the line, and the space above 6.5m on the rail surface is occupied, and the section about 9m long along the line direction cannot be erected. The flexible catenary can not use the inertia of the train to break through the non-electric area. It has become a common problem for the electric locomotive to pass through the funnel warehouse when it is charged. It is completed with double bows, which restricts the efficiency of the entire logistics chain
