In this embodiment, the weight 8 is disposed at the other end of the rotating swing arm 1, and in the rotating process of the rotating swing arm 1, the height of the weight 8 is kept unchanged, that is, the weight 8 does not rise or fall in the traditional sense.
As shown in fig. 6 and 7, in this embodiment, the rotary swing arm 1 rotates to drive the catenary and/or the contact line 3 to be at the first station or the second station; the first station state is as follows: the catenary and/or contact line 3 is/are positioned above the rail (in a closed state, a pantograph of the train is lifted to take power from the contact line, and the train drives in or out of a station in the closed state); the second station state is as follows: the messenger and/or contact wire 3 is located to one side of the rail (open condition, which is a train stop in either a loading or unloading or maintenance condition).
Rotate swing arm 1 and rotate rail side, have two kinds of modes, clockwise (toward the left) rotates rail side or anticlockwise (toward the right) rotates rail side, explains respectively below:
referring to fig. 1 and 6, the swing arm 1 rotates to above the rail, and at this time, fig. 6 shows that the angle α 1 between the force direction a 1' of the pulling rope 4 on the swing arm 1 and the force direction a1 of the messenger wire and/or the contact wire 3 is 90 °, where 90 ° is just an example, and the standard that the messenger wire and/or the contact wire 3 is above the rail is: the pantograph of the train is lifted up and can get electricity from the contact line. And not as limitations on the claims.
The rotating swing arm 1 is driven to rotate to one side of the rail, and at the moment, an included angle alpha 3 between the stress direction A3' of the pull rope 4 on the rotating swing arm 1 and the stress direction A3 of the carrier cable and/or the contact line 3 is 0 degree; at the moment, the stress direction of the pull rope 4 is superposed with the stress direction of the carrier cable and/or the contact line 3, and the movement to one side of the rail is completed. Here 0 ° is only an example illustration, and the criteria for the catenary and/or contact line 3 to be located on one side of the rail are: as long as one side of the rail is rotated, the space above the rail is vacated, so that the train can be conveniently parked, loaded and unloaded or overhauled, the angle can be close to 0 degree, and the train can rotate a few degrees.
In this embodiment, the swing arm 1 is closed when being positioned above the rail, and is opened when the swing arm 111 rotates clockwise (as shown by the arrow in fig. 6) to a position where one side of the rail is positioned on the left side of the gravity compensation device, and an angle between a force direction of the pull rope 44 on the swing arm 11 and a force direction of the messenger wire and/or the contact line 3 is changed from α 1 (about 90 °) to α 3 (about 0 °);
the angles a2 and a 2' and the applied force direction α 2 in fig. 6 show the applied force diagram during the rotation; when the swing arm 11 needs to be returned from one side of the rail to above the rail, the angle between the force direction of the pull rope 44 on the swing arm 11 and the force direction of the catenary and/or contact line 3 changes from about 0 ° to about 90 °.
According to the rotation principle, the length of the rotating swing arm 1 is taken as the radius to do back and forth arc movement, so that the catenary cable and/or the contact line 3 is driven to move from the upper part of the rail to one side of the rail, or the catenary cable and/or the contact line 3 is driven to return from one side of the rail to the upper part of the rail. The pull rope 4 only has the change of the included angle in the stress direction during the whole rotating process and does not generate displacement, so that the height of the balance weight 8 is kept unchanged, and the principle that the balance weight 8 is not moved during the switching of the opening and closing states of the flexible contact network is clearly expressed.
The balance weight 8 in the flexible contact network is used for adjusting the tension of the contact wire and the catenary and is an indispensable part, in the embodiment, the other end of the rotary swing arm 1 is taken as a round point, the length of the rotary swing arm 1 is taken as a radius, and the gravity of the gravity compensation device acts on the catenary and/or the contact wire 3; the pulling force direction provided by the gravity acting force points to the swinging round points of the rotating swinging arm 1; the rotating swing arm 1 rotates in the circumferential direction, so that the carrier cable and/or the contact line 3 are driven to translate.
The above-mentioned fig. 6 and the corresponding text refer to the case where the swing arm 1 is rotated clockwise.
According to the actual situation on site, the rotating swing arm 1 can be set to rotate anticlockwise to realize the switching of the opening and closing states.
Referring to fig. 1 and 7, the swing arm 1 is driven to rotate above the rail, and at this time, an angle β 1 between a force direction B1' of the pull rope 4 on the swing arm 1 and a force direction B1 of the messenger wire and/or the contact line 3 is about 90 °; the rotating swing arm 1 is driven to rotate to one side of the rail, and at the moment, an included angle beta 3 between the stress direction B3' of the pull rope 4 on the rotating swing arm 1 and the stress direction B3 of the catenary cable and/or the contact line 3 is about 180 degrees; at the moment, the stress direction of the pull rope 4 is opposite to the stress direction of the carrier cable and/or the contact line 3, and the movement to one side of the rail is completed.
The rotating swing arm 1 is in a closed state above a rail, when the rotating swing arm 1 rotates anticlockwise (in the arrow direction of fig. 7) to the state that one side of the rail is positioned on the right side of the gravity compensation device, the rotating swing arm 1 is in an open state, and an included angle between the stress direction of the pull rope 4 on the rotating swing arm 1 and the stress direction of the carrier cable and/or the contact line 3 is changed from beta 1 (about 90 degrees) to beta 3 (about 180 degrees);
b2 and B2' in FIG. 7 and the angle β 2 of the force direction thereof show the force-receiving schematic diagram during rotation; when the rotating swing arm 1 needs to return to the position above the rail from one side of the rail, the included angle between the stress direction of the pull rope 4 on the rotating swing arm 1 and the stress direction of the carrier cable and/or the contact line 3 is changed from about 180 degrees to about 90 degrees when the rotating swing arm 1 returns. In the whole rotating process, the pull rope 4 only changes the included angle in the stress direction and does not generate displacement, so the height of the balance weight 8 is kept unchanged,
in addition, it is to be added that the driving mode of the swing arm 1 of the present invention can adopt an electric push rod with a bidirectional working function or a hydraulic push rod with a bidirectional working function, in addition to the rotating motor 7 adopted in the above embodiments
The rotating swing arm 1 can be pulled to rotate by two external pulling motors. For example: one pulling motor rotates forwards to take up wires and pulls the rotating swing arm 1 to rotate to the right side, and the other pulling motor carries out wire paying-off in the process; the other pulling motor positively rotates to take up the wire and pulls the rotating swing arm 1 to rotate towards the left side, and at the moment, the pulling motor is pulled to pay off the wire.
It should be added that, in this embodiment, the pulling force direction provided by the gravity acting force of the gravity compensation device points to the other end of the rotating swing arm 1; referring to fig. 1 and 5, the pull rope 4 can be routed from above the rotating swing arm or from below the rotating swing arm, so that the pull direction provided by the weight 8 is directed to the other end of the rotating swing arm 1, and the most preferable mode is directed to the swing round point of the rotating swing arm. The balance weight adjusts the tension of the contact wire and the carrier cable through an acting force transmission structure. Therefore, the pulling force direction provided by the gravity acting force is directed to the other end of the rotating swing arm 1, and the pulling rope can also be upwards or downwards inclined at a certain angle with the horizontally arranged rotating swing arm, preferably (between 0 ° and 25 °), and does not necessarily be directed to the swinging round point of the rotating swing arm.
