Description

Technical Field

[0001] The present invention belongs to the field of movable catenaries for electrified railways, and particularly relates to a flexible movable catenary for large freight yards and containers and an operation method thereof. Background Art

[0002] With the advancement of railway electrification traction, electric locomotives have replaced diesel locomotives in the transportation of China's railway main lines. Electrification has been achieved in the loading and unloading lines or during in-station maintenance. Currently, rigid movable catenaries are used. However, the existing rigid movable catenary systems have extremely high costs, complex structures, inconvenient installation, high requirements for line usage conditions, and poor structural reliability. In this method, a motor is used to drive the rotation of a rotating bracket, thereby driving the moving section of the overall movable catenary to shift to one side of the railway track. In this way, the busbar is installed as a whole at the end of the rotating bracket, and there are many motors, making it difficult to control the synchronization of the motors or the electric push rods.

[0003] On the other hand, in the prior art, flexible movable catenaries are also used. A motor directly drags the carrier cable on one side of the flexible catenary to shift the contact wire to one side of the railway track. For a long-distance movable catenary with a full anchor section length, this method has defects such as insufficient towing force and unstable operation. Since only one counterweight is used, the length of the movable catenary generally does not exceed 800 m.

[0004] A heavy-haul train with a capacity of 10,000 tons is an extremely long and heavy freight train that uses double or multiple locomotives for traction. Its characteristics are: large vehicle load capacity; a large number of cars coupled in the train. According to the existing main railway technical policies, for a heavy-haul freight train with a capacity of 5,000 t, the effective length of the arrival and departure tracks at the station is 1,050 m. For a heavy-haul freight train with a capacity of 10,000 t operating on a dedicated coal transportation line, the effective length of the arrival and departure tracks at some stations is 1,700 m. It includes unit heavy-haul trains, combined heavy-haul trains, and integral heavy-haul trains.

[0005] For such long-distance heavy-haul trains, such as 1400 m to 1700 m 10,000-ton heavy-haul trains, if diesel locomotives are used for shunting operations, multiple cars need to be uncoupled, and the existing technology has high costs, and it is necessary to rent diesel locomotives and park them at the loading and unloading points. When the electric tractor arrives at the loading and unloading point, the diesel locomotive and the electric tractor need to be swapped, and the efficiency is extremely low. In order to be able to swap the traction vehicles, new parking lines and conversions also need to be built, increasing the investment. The key point is that there are no high-power locomotives among the current diesel locomotives, and they cannot tow heavy-haul trains. Summary of the Invention

[0006] To achieve the above object, the applicant provides a large freight yard and a flexible mobile catenary for containers that can effectively control the docking points, which has a lower cost, more reliable operation, less affected by weather, and simpler maintenance compared to the rigid catenary; the catenary provided in this application also overcomes the deficiency of the original method of moving by dragging, and instead uses the method of gravity compensation for movement. Based on the existing catenary, effective improvements are made to achieve integral movement over a longer distance (1600m - 1700m). In addition to being able to meet the requirements of the loading and unloading lines of freight trains of existing locomotives or the in - depot maintenance, it can also be effectively applied to heavy - haul trains such as ten - thousand - ton trains.

[0007] To achieve the above object, on the one hand, the present invention provides a large freight yard and a flexible mobile catenary for containers, including a mobile catenary, a first counterweight structure, and a second counterweight structure; wherein, the first counterweight structure is arranged at one end of the mobile catenary; the second counterweight structure is arranged at the other end of the mobile catenary; the carrier cable and / or the contact wire are longitudinally arranged along the length of the mobile catenary; the weight of the second counterweight structure is greater than the weight of the first counterweight structure; the weight of the first counterweight structure acts on one end of the carrier cable and / or the contact wire; the weight of the second counterweight structure acts on the other end of the carrier cable and / or the contact wire; and a rotation driving mechanism is further included, and the rotation driving mechanism is used to drive any one of the rotating cantilever structures on the upright post in the mobile catenary to rotate.

[0008] Further, the rotation driving mechanism drives any one of the rotating cantilever structures to rotate to control the carrier cable and / or the contact wire in the mobile catenary to be stationary, move towards the lighter first counterweight structure, or move towards the heavier second counterweight, so as to control the carrier cable and / or the contact wire in the mobile catenary to move above the railway track or to one side of the railway track.

[0009] Further, the weight of the second counterweight structure at the other end of the mobile catenary is greater than the weight of the first counterweight structure at one end of the mobile catenary, and the carrier cable and / or the contact wire in the mobile catenary always have a tendency to move towards the other end.

[0010] The rotation driving mechanism has three working states:

[0011] The first: The rotation driving mechanism stops acting, and the carrier cable and / or the contact wire in the mobile catenary are in a stationary state.

[0012] The second: The rotation driving mechanism drives the rotating cantilever structure, and the carrier cable and / or the contact wire in the mobile catenary move as a whole towards the other end, that is, towards the heavier second counterweight.

[0013] The third type: The rotation driving mechanism drives the rotating boom structure, and the carrier cable and / or the contact wire in the mobile catenary are integrally moved towards one end, that is, towards the lighter first counterweight structure.

[0014] Furthermore, the rotation driving mechanism includes a rotation motor, and the rotation motor is used to drive any one of the rotating boom structures in the mobile catenary to rotate, thereby driving the carrier cable and / or the contact wire in the entire mobile catenary to move above the railway track or to one side of the railway track.

[0015] Furthermore, the rotation driving mechanism includes an electric / hydraulic push rod, and the electric / hydraulic push rod is used to drive any one of the rotating boom structures in the mobile catenary to rotate, thereby driving the carrier cable and / or the contact wire in the entire mobile catenary to move above the railway track or to one side of the railway track.

[0016] Furthermore, one end of the carrier cable and / or the contact wire is arranged on the rotating boom structure of the first column, and the other end is arranged on the rotating boom structure of the last column;

[0017] The first fixing point structure and the second fixing point structure are arranged on the rotating boom structures of the first column and the last column;

[0018] One end of the carrier cable and / or the contact wire is arranged on the first fixing point structure in the rotating boom structure of the first column; the other end of the carrier cable and / or the contact wire is arranged on the first fixing point structure in the rotating boom structure of the last column;

[0019] Regarding the setting methods of the first counterweight structure and the second counterweight structure:

[0020] The first type:

[0021] The weight acting force provided by the first counterweight structure directly acts on one end of the carrier cable and / or the contact wire, or the weight acting force provided by the first counterweight structure acts on the second fixing point structure on the rotating boom structure of the first column; or

[0022] The second type:

[0023] The weight acting force provided by the second counterweight structure directly acts on the other end of the carrier cable and / or the contact wire; or the weight acting force provided by the second counterweight structure acts on the second fixing point structure on the rotating boom structure of the last column;

[0024] The third type: One end of the carrier cable and one end of the contact wire extend outwards and converge and then are connected to the first counterweight structure, or

[0025] The other end of the carrier cable and the other end of the contact wire extend outwards and converge and then are connected to the second counterweight structure.

[0026] Furthermore, the first fixed-point structure and the second fixed-point structure coincide. A mobile catenary positioning device is provided at the first fixed-point structure of the rotating boom structure, and the second fixed-point structure is arranged on the mobile catenary positioning device.

[0027] Furthermore, the mobile catenary positioning device has a carrier cable mechanism and a positioning mechanism. The carrier cable is arranged on the carrier cable mechanism, and the contact wire is arranged on the positioning mechanism;

[0028] It further includes an insulating connector. One end of the carrier cable and one end of the contact wire extend outwards and converge onto the insulating connector, and the weight of the first counterweight structure acts on the insulating connector; or

[0029] The other end of the carrier cable and the other end of the contact wire extend outwards and converge onto the insulating connector, and the weight of the second counterweight structure acts on the insulating connector.

[0030] On the other hand, the present invention also provides an operation method for a large freight yard and a flexible mobile catenary for containers, adopting the above-mentioned large freight yard and flexible mobile catenary for containers. The specific operation method is as follows:

[0031] A first counterweight structure is arranged at one end of the mobile catenary, and a second counterweight structure is arranged at the other end; the weight of the second counterweight structure is greater than the weight of the first counterweight structure;

[0032] The weight of the first counterweight structure acts on one end of the carrier cable and / or the contact wire; the weight of the second counterweight structure acts on the other end of the carrier cable and / or the contact wire;

[0033] Use the rotation drive mechanism to drive any one of the rotating boom structures on the upright column in the mobile catenary to rotate;

[0034] The rotation drive mechanism drives any one of the rotating boom structures to rotate to control the carrier cable and / or the contact wire in the mobile catenary to be stationary, move towards the lighter first counterweight structure, or move towards the heavier second counterweight structure, so as to control the carrier cable and / or the contact wire in the mobile catenary to move above the railway track or to one side of the railway track.

[0035] Furthermore, the weight of the second counterweight structure at the other end of the mobile catenary is greater than the weight of the first counterweight structure at one end of the mobile catenary, and the carrier cable and / or the contact wire in the mobile catenary always has a movement tendency towards the other end;

[0036] The weight of the second counterweight structure at the other end of the mobile catenary is greater than the weight of the first counterweight structure at one end of the mobile catenary, and the carrier cable and / or the contact wire in the mobile catenary always has a movement tendency towards the other end;

[0037] The rotation drive mechanism has three working states:

[0038] First: The rotation drive mechanism stops operating, and the carrier cable and / or contact wire in the mobile catenary are in a stationary state;

[0039] Second: The rotation drive mechanism drives the rotating boom structure, and the carrier cable and / or contact wire in the mobile catenary move as a whole towards the other end, i.e., the direction of the heavier second counterweight;

[0040] Third: The rotation drive mechanism drives the rotating boom structure, and the carrier cable and / or contact wire in the mobile catenary move as a whole towards one end, i.e., the direction of the lighter first counterweight structure.

[0041] The present invention has the following beneficial effects:

[0042] 1. By using the rotation drive mechanism, the carrier cable and / or contact wire in the mobile catenary are controlled to be stationary, move towards the lighter first counterweight structure, or move towards the heavier second counterweight, so as to control the carrier cable and / or contact wire in the mobile catenary to move above the railway track or to one side of the railway track.

[0043] 2. For the traditional rigid movable catenary, due to its complex structure, it needs to carry a rigid busbar, with many components and large weight, and the spacing between columns is 9 - 12M. For the mobile catenary provided by the present invention, the spacing between columns can be set at 40 - 50M. The carrier cable of the flexible catenary provided by the present invention is more evenly stressed, has a short construction period, is less affected by factors such as weather and temperature difference, can be widely applied in various harsh environments, has a long service life, can be improved on the basis of the existing catenary, and has many advantages such as convenient installation and maintenance, and a similar fixed catenary structure.

[0044] 3. In the traditional flexible movable catenary, the carrier cable is directly dragged unilaterally. For a long-distance mobile catenary, this method has insufficient pulling force. At the same time, the unilateral dragging method has great destructive effect on the structure of the catenary itself, has potential safety risks, and is unstable in operation. The present invention adopts the bilateral gravity balance method. The balance pulling mechanism only needs less external driving force to destroy the original balance system. Exactly for this reason, the present invention proposes to adopt the gravity compensation method to realize the movement of the flexible catenary. By setting counterweights on both sides, by destroying the balance relationship between the two counterweights, with less driving force, the overall movement of a long distance, such as (1600m - 1700m), is realized. This movement method is a pioneering work in the current movable flexible catenary, and it has not been found that the prior art or prior patents adopt the device provided by the present invention to realize the movement of the flexible movable catenary.

[0045] 3) By adopting the device provided by the present invention, the ten-thousand-ton heavy-haul train will no longer use diesel locomotives for shunting operations, overcoming the situation where traditional methods require multiple cars to be uncoupled and even being unable to tow heavy-haul trains. It can effectively meet the needs of the loading and unloading lines of ten-thousand-ton trains or the needs of in-storage maintenance and repair, improve work efficiency, and greatly save the cost of purchasing diesel locomotives and the labor costs for the deployment, maintenance, and repair of existing diesel locomotives.

The implementation modes described in the following exemplary embodiments do not represent all implementation modes consistent with the present invention. On the contrary, they are merely examples of devices consistent with some aspects of the present invention as detailed in the appended claims.

[0057] As Figure 1 and Figure 2 shown, this embodiment provides a large freight yard and a flexible mobile catenary for containers, including a mobile catenary 1, a first counterweight structure 2 and a second counterweight structure 3; wherein, the first counterweight structure 2 is arranged at one end of the mobile catenary 1; the second counterweight structure 3 is arranged at the other end of the mobile catenary 1; the carrier cable 4 and / or the contact wire 5 are arranged longitudinally along the length of the mobile catenary; the weight of the second counterweight structure 3 is greater than the weight of the first counterweight structure 2; the weight of the first counterweight structure 2 acts on one end of the carrier cable and / or the contact wire 5; the weight of the second counterweight structure 3 acts on the other end of the carrier cable and / or the contact wire 5;

[0058] It further includes a rotation driving mechanism, and the rotation driving mechanism is used to drive any one of the rotating boom structures on the columns in the mobile catenary to rotate. The rotation driving mechanism drives any one of the rotating boom structures to rotate to control the carrier cable and / or the contact wire in the mobile catenary to be stationary, move towards the lighter first counterweight structure direction or move towards the heavier second counterweight direction, so as to control the carrier cable and / or the contact wire in the mobile catenary to move above the railway track or to one side of the railway track.

[0059] In this embodiment, the weight of the second counterweight structure at the other end of the mobile catenary is greater than the weight of the first counterweight structure at one end of the mobile catenary, and the carrier cable and / or the contact wire in the mobile catenary always have a movement tendency towards the other end; the rotation driving mechanism has three working states:

[0060] The first one: The rotation driving mechanism stops operating, and the carrier cable and / or the contact wire in the mobile catenary are in a stationary state;

[0061] The second type: The rotation driving mechanism drives the rotating boom structure to move the carrier cable and / or the contact wire in the mobile catenary as a whole towards the other end, i.e., the heavier second counterweight direction.

[0062] The third type: The rotation driving mechanism drives the rotating boom structure to move the carrier cable and / or the contact wire in the mobile catenary as a whole towards one end, i.e., the lighter first counterweight structure direction.

[0063] As a preferred embodiment, as Figure 2 shown, in this embodiment, the rotation driving mechanism includes a rotation motor 6, and the rotation motor is used to drive any one of the rotating boom structures in the mobile catenary to rotate, thereby driving the carrier cable and / or the contact wire in the whole mobile catenary to move above the railway track or to one side of the railway track. The rotating boom structure is arranged on the column through a rotating shaft, and the rotation motor drives the rotating shaft to rotate to drive the rotating boom structure to rotate.

[0064] As a preferred embodiment, as Figure 3 shown, in this embodiment, the rotation driving mechanism includes an electric / hydraulic push rod 7, and the electric / hydraulic push rod is used to drive any one of the rotating boom structures in the mobile catenary to rotate, thereby driving the carrier cable and / or the contact wire in the whole mobile catenary to move above the railway track or to one side of the railway track. The electric / hydraulic push rod is arranged on the column, and the electric / hydraulic push rod is used to push the rotating boom structure to rotate.

[0065] Please refer to Figure 1 shown, as a preferred embodiment, in this embodiment, one end of the carrier cable and / or the contact wire 5 is arranged on the rotating boom structure 8 of the first column, and the other end is arranged on the rotating boom structure 9 of the last column.

[0066] As Figure 2 shown, for further supplementary explanation with the left end top view of the mobile catenary 1, the first fixed point structure A and the second fixed point structure B are arranged on the rotating boom structures of the first column and the last column;

[0067] One end of the carrier cable and / or the contact wire 5 is arranged on the first fixed point structure A in the rotating boom structure 8 of the first column; the other end of the carrier cable and / or the contact wire 5 is arranged on the first fixed point structure A in the rotating boom structure 9 of the last column;

[0068] Here, it should be supplemented that the first and second fixed point structures are intended to illustrate the spatial positions of the rope connections. As for the structures of the fixed point structures themselves, they are not the points protected by this patent. For the purpose of public disclosure, several implementation methods are provided. For example, the rope can be directly tied to the first or second fixed point, or corresponding hooks can be configured at the first or second fixed point, as long as it is convenient to tie the rope.

[0069] In this embodiment, preferably, the first fixed point is set at the free end of the rotating wrist arm, and the second fixed point is set at any position on the rotating wrist arm body.

[0070] In order to facilitate the installation of the carrier cable and the contact wire 5, in this embodiment, a mobile catenary positioning device 10 is installed at the first fixed point, that is, the free end of the rotating wrist arm. The mobile catenary 1 positioning device has a carrier cable mechanism 101 and a positioning mechanism 102. The carrier cable 4 is arranged on the carrier cable mechanism 101, and the contact wire 5 is arranged on the positioning mechanism 102.

[0071] Of course, there is a case where the first fixed point and the second fixed point coincide. The explanation of this embodiment is as follows: Install the mobile catenary positioning device at the first fixed point, that is, the free end of the moving wrist arm, and the second fixed point is set at any position of the positioning device (such as Figure 1 point C in it), as long as the rope can be tied to achieve dragging. This is used as an explanation for the coincidence of the first fixed point structure and the second fixed point structure.

[0072] As an actual application situation, in actual working conditions, there is only the contact wire 5, and there is also a situation where the catenary and the carrier cable exist at the same time.

[0073] Such as Figure 6 shown, but when both the contact wire 5 and the carrier cable are used at the same time, in order to facilitate the connection with the first and second counterweight structures, an insulating connector 11 can be set. One end of the carrier cable and one end of the contact wire 5 extend outwards and converge on the insulating connector, and the weight of the first counterweight structure 2 acts on the insulating connector; or

[0074] The other end of the carrier cable and the other end of the contact wire 5 extend outwards and converge on the insulating connector, and the weight of the second counterweight structure 3 acts on the insulating connector 11.

[0075] The above discussion is about the connection situation of the carrier cable and the contact wire 5 in actual working conditions. Next, the connection method of the counterweight structure in this patent will be specifically discussed:

[0076] The first type:

[0077] The weight acting force provided by the first counterweight structure 2 directly acts on one end of the carrier cable and / or the contact wire 5, or the weight acting force provided by the first counterweight structure 2 acts on the second fixed point structure on the first column rotating wrist arm structure;

[0079] Figure 5It is a schematic structural diagram in which the weight acting force provided by the first counterweight structure 2 directly acts on the contact wire 5;

[0080] Figure 6 It is a schematic structural diagram in which the weight acting force provided by the first counterweight structure 2 directly acts on the carrier cable and the contact wire 5;

[0082] Or

[0083] The second type:

[0084] The weight acting force provided by the second counterweight structure 3 directly acts on the other end of the carrier cable and / or the contact wire 5; or the weight acting force provided by the second counterweight structure 3 acts on the second fixing point structure on the rotating boom structure of the last upright post;

[0085] It should be added that for the setting method of the second counterweight structure 3, refer to the setting method of the first counterweight, see Figures 4 to 7 That's it.

[0086] The third type:

[0087] As a special setting method: as Figure 6 shown, one end of the carrier cable and one end of the contact wire 5 extend outwards and converge and then are connected to the first counterweight structure 2, or

[0088] The other end of the carrier cable and the other end of the contact wire 5 extend outwards and converge and then are connected to the second counterweight structure 3. The setting method of the other end is not shown in the figure.

[0089] As Figure 8 shown, on the other hand, the present invention provides a method for operating a large freight yard and a container flexible mobile catenary. Using the large freight yard and container flexible mobile catenary of the above rights, the specific operation method is as follows:

[0098] Second: The rotation driving mechanism drives the rotating boom structure, and the carrier cable and / or the contact wire in the mobile catenary as a whole moves towards the other end, i.e., the heavier second counterweight;
