Description

Gravity compensation type mobile contact net and operation control method

Technical Field

The invention belongs to the field of electrified railway mobile contact networks, and particularly relates to a gravity compensation type mobile contact network and an operation control method.

Background

With the propulsion of the electric traction of railways, the electric locomotives are adopted to replace the internal combustion locomotives in the transportation of China railway trunks. Electrification is realized in a cargo loading and unloading line or warehousing maintenance. At present, a rigid movable contact net system is adopted, but the existing rigid movable contact net system has extremely high cost, complex structure and inconvenient installation, has high requirements on the use conditions of the line and poor structural reliability; the motor is used for driving the rotating support to rotate so as to drive the moving section of the overall moving contact net to move to one side of a rail, in the mode, the bus bar is integrally arranged at the tail end of the rotating support, and the motor is more and difficult to control the synchronism of the motor or the driving of the electric push rod.

On the other hand, in the prior art, a flexible movable contact net is also used, a motor is adopted to directly drag a catenary on one side of the flexible contact net, so that the contact line is laterally moved to one side of a rail, and the mode has the defects of insufficient dragging force, unstable operation and the like for a long-distance movable contact net with an integral anchor section; because only one balance weight is adopted, the length of the movable contact net is generally not more than 800 m.

The ten thousand ton heavy load train adopts a double-machine or multi-machine traction running super-long and super-heavy cargo train, which is characterized in that: the vehicle has large load capacity; the number of trains is large. According to the main technical policy of the existing railway, 5000t heavy-load freight trains are driven, the effective length of the arrival and departure line of a station is 1050m, 10000t heavy-load freight trains are driven on a special coal conveying line, and the effective length of the arrival and departure line of part of stations is 1700 m. Comprises a unit type heavy-duty train, a combined type heavy-duty train and an entire-row type heavy-duty train.

For such a long-distance heavy-duty train, for example, a ten thousand-ton heavy-duty train of 1400m to 1700m, if the diesel locomotive is used for shunting operation, a plurality of trains need to be separated, and the existing technology has high cost and needs to rent the diesel locomotive to stop at a loading and unloading point; when the electric tractor reaches a loading and unloading point, the internal combustion engine and the electric tractor need to be exchanged, so that the efficiency is extremely low; in order to exchange the traction vehicles, new stop lines and switching lines are required, and the investment is increased. The key point is that the existing diesel locomotive has no high-power locomotive and cannot pull a heavy-load train. In the current flexible contact net technology, the technology comprising the prior practical application and the prior patent application document have no flexible movable contact net which can meet the cargo handling line or warehousing maintenance of a ten-thousand-ton train.

The movable contact net comprises a plurality of stand columns 7, each stand column is provided with a rotary swing arm 8 capable of rotating around the stand column, and the catenary 5 is arranged on the rotary swing arm.

In the gravity compensation type mobile catenary provided by this embodiment, when the first and second gravity catenary compensation devices are both in a balanced state via the catenary 5 and/or the contact line 4, the contact line in the mobile catenary is in a first station state or a second station state; in this embodiment, the first station state is that the mobile catenary is located above the rail (as shown in fig. 1B), and the second station state is that the mobile catenary is located on one side of the rail (as shown in fig. 1C).

It should be added that in this embodiment, the gravity catenary compensation device is connected to both the catenary wire 5 and/or the contact wire 4, which is only an optimal embodiment. If only connected with the carrier cable 5, the movement of the carrier cable 5 can drive the hanging contact line to move together. In some cases, if only a contact wire is provided, the gravity contact net compensation device is only connected with the contact wire 4 to realize movement, and the contact wire close to the balance weight can be connected with a pull wire of the balance weight by using an insulator. The principle of this embodiment is the same, and will not be described herein.
