Technical Field

The invention belongs to the field of electrified railway mobile contact networks, and particularly relates to a flexible mobile contact network for a large goods yard and a container and an operation method thereof.

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, the stop line needs to be repaired and converted newly, 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.

the balance pulling mechanism 6 is further included, and the balance pulling mechanism 6 controls the messenger wire and/or the contact wire 5 in the moving contact net 1 to be in a static state, move towards the first weight structure 2 with a lighter weight or move towards the second weight structure with a heavier weight, so that the messenger wire and/or the contact wire 5 in the moving contact net 1 is controlled to move above a rail or to one side of the rail.

In this embodiment, because the weight of the second weight structure 3 at the other end (right end) of the mobile contact network 1 is greater than the weight of the first weight structure 2 at one end (left end) of the mobile contact network 1, the catenary and/or the contact line 5 in the mobile contact network 1 always have a movement trend toward the other end (right); the balance pulling mechanism in the large goods yard and container flexible mobile contact network 1 provided by this embodiment controls the messenger wire and/or the contact wire 5 in the mobile contact network 1 to be at a standstill, move towards the direction of the first weight structure 2 which is relatively light, or move towards the direction of the second weight which is relatively heavy, so as to control the messenger wire and/or the contact wire 5 in the mobile contact network 1 to move above the rail or to one side of the rail. Under the condition that the contact line 5 in the mobile contact network 1 has a motion trend, the motion state of the contact line is controlled by adopting a balance pulling mechanism, and the defect that the parking place of the whole mobile contact network 1 in the motion process cannot be accurately controlled can be overcome.

The first embodiment:

as shown in fig. 2, as a preferred embodiment, the balance pulling mechanism provided in this embodiment includes a dragging motor 7, where the dragging motor 7 is disposed at one end of the moving catenary 1; the dragging power provided by the dragging motor 7 acts on the catenary and/or the contact wire 5 at one end of the mobile contact line 1 (the dragging power can directly act on the catenary and/or the contact wire 5, and can also indirectly act on the catenary and/or the contact wire 5). It should be added that the dragging force can act directly on the messenger wire and/or the contact wire 5, or act on the rotating wrist structure, and the purpose of driving the messenger wire and/or the contact wire 5 to move is realized by dragging the rotating wrist structure.

The weight of the second balance weight structure 3 at the other end of the movable contact net 1 is larger than that of the first balance weight structure 2 at one end of the movable contact net 1, and a catenary and/or a contact line 5 in the movable contact net 1 always has a movement trend towards the other end;

referring to fig. 2 and 3, the balance pulling mechanism in this embodiment has three working states:

the first method comprises the following steps: the balance pulling mechanism stops acting, the length of a pull rope of the balance pulling mechanism (a pulling motor 7) is kept unchanged, and a carrier cable and/or a contact wire 5 in the mobile contact net 1 are/is in a static state;

and the second method comprises the following steps: the balance pulling mechanism is in a wire releasing state, the length of a pull rope of the balance pulling mechanism (a pulling motor 7) is lengthened, and the carrier cable and/or the contact wire 5 in the contact net 1 are moved to the other end, namely the direction of the heavier second weight (to the right);

and the third is that: the balance pulling mechanism is in a wire winding state, the stay cord of the balance pulling mechanism (the pulling motor 7) is wound in length, and the carrier cable and/or the contact wire 5 in the movable contact net 1 integrally moves towards one end, namely the direction of the lighter first balance weight structure 2 (moves towards the left).

Fig. 3 shows a schematic diagram that the contact wire 5 is located above the center line of the rail and electrically connected with the main line contact wire 5, when the pull rope of the towing motor 7 is wound up in length, the rotating wrist-arm structure swings left, the contact wire 5 is separated from the main line contact wire 5, and the carrier cable and/or the contact wire 5 in the moving contact net 1 integrally moves towards one end, i.e. the direction of the lighter first weight structure 2, i.e. moves to one side of the railway. At this time, the loading and unloading or the maintenance work of the freight train can be performed.

When the length of the pull rope of the dragging motor 7 is lengthened, the whole carrier cable and/or the contact line 5 in the movable contact net 1 moves towards the other end, namely the direction of the heavier second weight (moves towards the right), even if the carrier cable and/or the contact line moves above the central line of the railway, the contact line 5 is electrically connected with the contact line 5 of the main line, and at the moment, the freight train moves into or out of the freight station.

Because the balance weight structure at the other end is heavy, the movable contact net 1 has a tendency of moving towards the heavier balance weight structure, the balance pulling mechanism is in a stop action state, at any time when the pull rope is released or wound, the pulling force provided by the balance pulling mechanism is used as an accurate regulation and control force, and the pulling force provided by the balance pulling mechanism and the weight pulling force provided by the first balance weight structure 2 act on one end of the movable contact net 1 together. Therefore, in the whole working state of the mobile contact net 1, the carrier cable and/or the contact line 5 are/is in effective tension control, and the defect that the original whole mobile contact net cannot be stopped immediately due to inertial motion caused by the swing of the whole mobile contact net is completely overcome.

In the first embodiment, an auxiliary driving device may be provided at the second weight structure 3, which is relatively heavy, and the auxiliary driving device lifts the second weight structure 3 due to the auxiliary balance pulling mechanism;

the auxiliary driving device has the following structural schemes:

as shown in fig. 4, the first way: an auxiliary lifting motor 8 is adopted to pull the second balance weight structure 3 to move upwards; in this embodiment, the auxiliary lifting motor 8 is disposed on the weight frame, and the auxiliary lifting motor 8 acts on the second weight structure 3 through a pull rope. Because the weight of the second balance weight structure 3 is large, the auxiliary lifting motor 8 can be adopted to pull the second balance weight structure 3 to move upwards.

As shown in fig. 5, the second way: an electric/hydraulic push rod 99 is arranged above the second balance weight structure 3 and pulls the second balance weight structure 3 to move;

as shown in fig. 6, the third method: an electric/hydraulic push rod 99 is arranged below the second balance weight structure 3 to push the second balance weight structure 3 to move.

The second embodiment:

as shown in fig. 7, the balance pulling mechanism comprises a pulling motor 10, and the pulling motor 10 is arranged at the other end of the mobile overhead line system 1; the pulling power provided by the pulling motor 10 acts on the second balance weight structure 3 at the other end of the movable contact net 1.

the balance pulling mechanism has three working states:

the first method comprises the following steps: the balance pulling mechanism stops acting, the length of a pull rope of the balance pulling mechanism (a pulling motor 10) acting on the second balance weight structure 3 is kept unchanged, the height of the second balance weight structure 3 is kept unchanged, and a carrier cable and/or a contact wire 5 in the mobile contact net 1 are/is in a static state;

and the second method comprises the following steps: the balance pulling mechanism is in a wire releasing state, the length of a pull rope acted on the second balance weight structure 3 by the balance pulling mechanism (a pulling motor 10) is lengthened, the second balance weight structure 3 descends, and a carrier cable and/or a contact wire 5 in the movable contact net 1 integrally moves towards the other end, namely the direction of the heavier second balance weight;

and the third is that: the balance pulling mechanism is in a wire winding state, the pull rope acting on the second balance weight structure 3 by the balance pulling mechanism (the pulling motor 10) is wound by length, the second balance weight structure 3 rises, and the carrier cable and/or the contact wire 5 in the movable contact net 1 integrally moves towards one end, namely the lighter first balance weight structure 2.

Because the balance pull mechanism (the lifting motor 10) is in a stop state, at any time when the pull rope is released or wound, the lifting force provided by the balance pull mechanism is used as an accurate regulating force, the lifting motor 10 lifts the second balance weight structure 3, and the carrier cable and/or the contact wire 5 in the movable contact net 1 integrally moves towards one end, namely the direction of the lighter first balance weight structure 2; the length of a pull rope acted on the second balance weight structure 3 by the lifting motor 10 is lengthened, the second balance weight structure 3 descends, and a carrier cable and/or a contact line 5 in the contact net 1 are moved to the other end, namely the direction of the heavier second balance weight; therefore, in the whole working state of the mobile contact net 1, the carrier cable and/or the contact line 5 are/is in effective tension control, and the defect that the original whole mobile contact net cannot be stopped immediately due to inertial motion caused by the swing of the whole mobile contact net is completely overcome.

As shown in fig. 1 and 7, as a preferred embodiment, one end of the catenary and/or contact line 5 is disposed on the rotating arm structure 11 of the first column, and the other end is disposed on the rotating arm structure 12 of the last column.

As shown in fig. 9, fig. 9 is a top view of the left end of the mobile catenary 1, which is further supplemented with fig. 2, and a first fixing point structure a and a second fixing point structure B are arranged on the rotating wrist arm structures of the first upright and the last upright;

as shown in fig. 9, one end of the messenger and/or contact line 5 is arranged at a first fixed point structure a in the swivel wrist structure 11 of the first upright; the other end of the carrier cable and/or the contact line 5 is arranged on a first fixed point structure A in the rotating wrist-arm structure 12 of the last upright post;

it should be added here that the first and second fixing point structures are intended to illustrate the spatial position of the rope connection, and the structure of the fixing point structure itself is not a point of protection of this patent, and for the purpose of illustration disclosure, several embodiments are provided, such as directly tying the rope at the first or second fixing point, or arranging a corresponding hook at the first or second fixing point, as long as the rope can be conveniently tied.

As shown in fig. 9, the first fixing point is preferably provided at the free end of the swivel arm in this embodiment, and the second fixing point is provided at an arbitrary position of the swivel arm body.

Referring to fig. 7, in order to facilitate the installation of the messenger and the contact wire 5, in this embodiment the mobile catenary positioning device 13 is installed at the first fixed point, i.e. the free end of the swivel cantilever, the mobile catenary 1 positioning device has a messenger mechanism 131 and a positioning mechanism 132, the messenger 4 is arranged on the messenger mechanism 131, the contact wire 5 is arranged on the positioning mechanism 132,

of course, there is a case where the first fixed point and the second fixed point coincide, and the explanation of the present embodiment is as follows: the movable contact net 1 positioning device is arranged at the first fixed point, namely the free end of the movable cantilever, the second fixed point is arranged at any position (such as a point C in fig. 7) of the positioning device, and the dragging can be realized as long as the rope can be tied. This is described as the coincidence of the first anchor point structure and the second anchor point structure.

As a practical application situation, in an actual working condition, there is a situation that only the contact wire 5 exists, and there is a situation that the contact wire and the catenary wire exist at the same time.

When the contact wire 5 and the carrier cable are adopted at the same time, an insulating connecting piece 14 can be arranged to facilitate the connection with the first and second balance weight structures, one end of the carrier cable and one end of the contact wire 5 extend outwards and are converged on the insulating connecting piece, and the weight of the first balance weight structure 2 acts on the insulating connecting piece; or

The other end of the carrier cable and the other end of the contact wire 5 extend outwards and are converged on the insulating connecting piece, and the weight of the second balance weight structure 3 acts on the insulating connecting piece 14.

And the third is that:

The other end of the carrier cable and the other end of the contact line 5 extend outwards and are connected with the second balance weight structure 3. The other end is not shown in the figure, and can be seen in the arrangement of fig. 12.
