Description

Gravity compensation type mobile contact net and operation control method

Technical Field

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 used for directly dragging a catenary on one side of the flexible contact net to enable the contact line to move to one side of a rail, and the mode has the defects of insufficient dragging force, unstable operation and the like for the movable contact net with a long distance of 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 existing flexible contact net technology, the technology comprising the existing 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.

Rather, they are merely examples of apparatus consistent with certain aspects of the invention, as detailed in the appended claims.

As shown in fig. 1, specifically referring to fig. 1A, 1B and 1C, the embodiment provides a gravity compensation type mobile catenary, including a mobile catenary 1, a first gravity catenary compensation device 2 and a second gravity catenary compensation device 3; the first gravity contact net compensation device and the second gravity contact net compensation device are respectively arranged at two ends of the movable contact net 1; the first gravity contact net compensation device and the second gravity contact net compensation device enable a catenary 6 and/or a contact line 7 in the mobile contact net 1 to be in a tensioning state, and at least one rotary swing arm 5 in the mobile contact net 1 provides a swing driving force so as to adjust the working state of the whole mobile contact net 1. The mobile contact net 1 comprises a plurality of upright posts 4, each upright post 4 is provided with a rotary swing arm 5 capable of rotating around the upright post 4, in the embodiment, a catenary 6 and a contact line 7 are arranged on the rotary swing arm 5; depending on the actual use, only a single contact line 7 may be provided on the rotary oscillating arm 5.

In the embodiment, the first gravity contact net compensation device 2 comprises a first balance weight 8, and the second gravity contact net compensation device 3 comprises a second balance weight 9; the device further comprises a first pendant weight frame 10 and a second pendant weight frame 11, wherein the first pendant weight 8 is arranged on the first pendant weight frame 10, and the second pendant weight 9 is arranged on the second pendant weight frame 11. The first balance weight 8 is arranged at one end of a carrier cable 6 and/or a contact line 7 in the mobile contact network 1; the second balance weight 9 is arranged at the other end of the catenary 6 and/or the contact line 7 in the movable contact net 1. The first balance weight 8 and the second balance weight 9 enable the catenary 6 and/or the contact line 7 in the mobile contact net 1 to be always in a tension state through the weight of the balance weights from two sides.

In this embodiment, when the first gravity contact net compensation device and the second gravity contact net compensation device are both in a balanced state through the catenary 6 and/or the contact line 7, the contact line 7 in the mobile contact net 1 is in a first station state or a second station state; when the first gravity contact net compensating device and the second gravity contact net compensating device are in an unbalanced state through the catenary 6 and/or the contact line 7, the contact line 7 in the movable contact net 1 is driven to move from a first station state to a second station state; alternatively, the contact wire 7 in the moving catenary 1 moves from the second station state to the first station state. The first station state is that the mobile contact net 1 is located above the rail, and the second station state is that the mobile contact net 1 is located on one side edge of the rail.

In the invention, the balance weights on the two sides are symmetrically arranged, and balance weights with equal weight are preferably adopted, so that, in equilibrium the carrier line 6 is understood to be in equilibrium, not moving side to side, and in this embodiment for the sake of explanation, as shown in fig. 1B and 1C, the left movement of the catenary 6 is defined as moving the contact wire 7 to one side of the rail (open state, which is the state where the train is parked in loading, unloading or maintenance), and the right movement of the catenary 6 is defined as moving the contact wire 7 back to the right above the rail (the state where the pantograph of the train is lifted up to take power from the contact wire 7, which is the state where the train is entering or exiting the station), although this left and right definition is not a limitation to the protection of the present invention, and as such, according to practical conditions, the catenary 6 can be defined to move to the right as the contact line 7 moves to one side of the rail, and the principle is the same, and the description is omitted here.

It should be added that in this embodiment, the gravity catenary compensation device is connected to both the catenary wire 6 and/or the contact wire 7, which is only an optimal embodiment.

The general idea is as follows: the embodiment also comprises a power supply device for driving at least one rotary swing arm 5 to rotate, wherein the power supply device is used for driving at least one rotary swing arm 5 to rotate to drive the whole catenary 6 and/or contact wire 7 to swing, so that the contact wire 7 in the mobile contact network 1 is driven to move from a first station state to a second station state in an unbalanced state; or from the second station state to the first station state.
