Description

Technical Field

[0001] The present invention belongs to the field of electrified railway mobile contact network, and in particular relates to a folding and sinking support device, a mobile contact network and an operating method. Background Art

[0002] Railway freight transport boasts large volumes, high speeds, low costs, and is generally unaffected by climatic conditions, making it suitable for long-distance transportation of bulky and heavy goods. Large freight trains require loading, unloading, and handling operations, as well as maintenance at railway loading and unloading yards.

[0003] Traditionally, diesel engines were used to pull freight trains at freight stations. This approach required specialized personnel to maintain the diesel engines, and the locomotives needed to be replaced whenever a freight train entered or left the station, resulting in low efficiency and high maintenance costs. With the development of electrified railway transportation technology, electric locomotives are increasingly being used to directly pull freight trains entering and leaving stations. This necessitates the installation of movable contact networks at freight stations. These networks power the locomotives when the freight trains enter or leave the station. When a freight train enters a station for loading and unloading, the contact networks need to be removed to facilitate loading and unloading operations.

[0004] In the existing mobile contact network, when a freight train is carrying out loading and unloading operations, the arm support structure of the mobile contact network swings sideways to the side of the railway. When the freight train needs to enter or exit the freight station, the arm support structure drives the moving contact wire to move above the railway, and the pantograph of the freight train is raised to obtain power, allowing the freight train to enter or exit.

[0005] The mobile contact network is installed at the freight station and along the length of the rail. The posts of the mobile contact network are about 3 meters away from the center of the railway and the height of the posts is at least 7 meters. In this case, freight loading and unloading can generally only be carried out on the other side of the railway (the side where the contact network is not installed).

[0006] There are two issues: one-sided loading is inefficient; and freight yards primarily transport large materials like coal and steel. Existing railway freight loading and unloading stations rely on forklifts, cranes, gantry cranes, and other equipment to lift cargo. These loading devices can easily come into contact with columns, arm support structures, or contact wires, damaging the mobile catenary and potentially causing safety accidents. Summary of the Invention

[0007] In view of this, the purpose of the present invention is to solve the shortcomings of the existing related technologies and provide a device that can lower the arm support structure from a high position, and then fold the column to tilt or lower it, so as to effectively hide the entire mobile contact network, free up space above the railway, and eliminate the adverse effects of the original railway side columns and arm support structure being easily touched by cargo lifting equipment.

[0051] A second aspect of the present invention provides a mobile contact network, in which the above-mentioned folding sinking support device is adopted.

[0052] A third aspect of the present invention provides a method for operating a sinking mobile contact network. The mobile contact network in the operating method adopts the above-mentioned mobile contact network, or the mobile contact network in the operating method adopts the above-mentioned folding sinking support device. The operating method is as follows:

[0053] How to descend:

[0054] The cantilever support structure descends along the height-variable guide structure, driving the conductor to descend;

[0055] The height of the conductor after being driven down by the cantilever support structure can be at least lower than the height of the roof of the freight train;

[0056] After the cantilever support structure descends, the height-variable guide structure is driven to flip over and is in a dumping or descending state; or

[0057] Ascending operation method:

[0058] The variable height guide structure is driven to be in a vertical or raised state;

[0059] The cantilever supporting structure enters the height-variable guiding structure and rises along the height-variable guiding structure.

[0060] Preferably, the height-variable guide structure is arranged on a column; it also includes a column structure, on which an additional guide structure is arranged; the arm support structure can drive the conductor to descend from the height-variable guide structure to another height-variable guide structure; or the arm support structure can drive the conductor to rise from the additional guide structure to the height-variable guide structure.

[0061] Preferably, the moving device drives the cantilever support structure to move downward along the height-variable guide structure on the column;

[0062] The cantilever support structure drives the conductor to move from the high column to the low column structure;

[0063] After the cantilever support structure leaves the height-variable guide structure of the column, the column is driven to switch from a vertical or raised state to a dumped or lowered state.

[0064] Preferably, the column is driven to switch from a tilted or lowered state to a vertical or raised state;

[0065] The columns are folded over the column structure;

[0066] The cantilever support structure drives the conductor to move from the lower column structure to the higher column;

[0067] Preferably, the driving mechanism is used to drive the moving device to drive the arm support structure to move downward from the column to the column structure; or to move upward from the column structure to the column.

[0068] Preferably, the moving device is driven by a driving motor to move via a rack; or the moving device is driven by a winch to move via a pull rope.

[0069] In the prior art, the arm support structure is rotatably mounted on the column, and the arm support structure swings to the top of the railway (working position) or to the side of the railway (non-working position). In the present invention, the column needs to be tilted or lowered. The advantage of tilting or lowering is that it drives the entire mobile contact to the ground, freeing up the space above, which is conducive to cargo loading and unloading, providing a larger cargo loading and unloading space, and at the same time reduces the damage caused by the lifting equipment touching the mobile contact network during the original cargo loading and unloading process, such as touching the contact line, the arm structure, etc. Therefore, tilting or lowering the column has great benefits.

[0070] There is no record about this block in the existing current technology. It only provides the method of driving the arm to tilt (or drop) through the column. However, the biggest problem with this method is that during the tilting (or dropping) of the column, the arm structure must also tilt (or drop) to a corresponding angle. Therefore, a key core idea of the present invention is that since the tilting (or dropping) of the column will exert additional force on the arm support structure, it is easy to cause uneven tension between the columns. The column directly drives the arm support structure to tilt (or drop), and the tension on the load-bearing cable and the contact line will be converted into a torsion on the arm structure itself. This torsion will cause the arm structure itself to deform, and will also be accompanied by bending of the load-bearing cable and / or contact line. The idea of the present invention directly abandons this method. Is it necessary for the column to drive it? Can the tilting (or dropping) of the column be separated from the arm support structure, so as to overcome the problems caused by the tilting (or dropping) of the column.

[0071] Therefore, the present invention adopts at least two-section columns, and the columns can be folded onto the column structure to form an integral column that is closed in the length direction; when the whole is closed, the columns can be used as the running track of the moving device, and the wrist support structure can drive the load-bearing cable and / or the contact line to move up and down. When the column needs to be tilted (or lowered) to make room above, one method that can be adopted is that the wrist support structure is at a higher position of the column, and the wrist support structure is driven to sink by tilting (or lowering) the column; and the present invention opens up a new idea, first sinking the wrist support structure to the bottom of the column, and then it can be suspended in the air after sinking, act on the load-bearing structure, or descend to another height-variable guide structure; then the column above the wrist support structure is folded and tilted (or lowered) by breaking or folding, which overcomes the shortcomings brought about by the direct tilting (or lowering) of the wrist support structure at a higher position of the column, as long as the tilting (or lowering) of the column can be driven by a driving device.

[0072] In the present invention, the columns are flipped and tilted (or lowered) to effectively hide the entire mobile contact network, freeing up space above the railway and eliminating the adverse effects of the original railway side columns and arm support structures being easily touched by cargo lifting equipment. The driving method of the arm support structure in the working position and non-working position is not the core focus of the present invention that needs to be protected, and will be briefly supplemented in the embodiments. During the movement of the method provided by the present invention, the load-bearing cables and contact wires maintain a relatively constant tension; the contact wires and load-bearing cables do not bend; and the arm structure does not suffer from deformation due to pulling.

In the following description, when referring to the drawings, like numbers in different figures represent like or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present invention, as detailed in the appended claims.

[0082] like Figures 1 to 5 As shown, the first aspect of this embodiment provides a foldable sinking support device, which at least includes an arm support structure 3, a height-variable guide structure 4 and a conductor 5; the conductor 5 is directly or indirectly arranged on the arm support structure 3; the arm support structure 3 can drive the conductor 5 to rise or fall along the guide mechanism.

The height-variable guiding structure 4 is arranged on the column 1, and the arm support structure 3 can rise or fall along the column 1 through the height-variable guiding structure 4.

[0090] It should be noted that, after the cantilever support structure 3 descends and leaves or detaches from the height-variable guide structure 4, there are several ways to install and set the cantilever support structure 3:

[0091] The first method is to use a bearing structure. When the arm support structure 3 drops away from or detaches from the height-variable guide structure 4, the arm support structure 3 falls onto the bearing structure.

[0092] The second type: the arm support structure 3 is suspended after leaving the height-variable guide structure 4 .

To better ensure the stability of the column structure 2, this embodiment further includes a column structure 2, and the guide structure 41 is disposed on the column structure 2.

[0095] The height-variable guide structure in this embodiment can be driven to switch between two states: a tilted state and a vertical state; or a lowered state and a raised state;

[0096] When the height-variable guide structure is in a vertical or raised state, the arm support structure can transition from the height-variable guide structure to another guide structure; or

[0099] In the first embodiment, when the column is in a tilted or descending state; or

[0100] The second: during the switching process between the column's tilted and upright states; or

[0101] The third type: during the switching process between the column lowering and raising states;

[0102] The arm support structure is located on a guide structure that is additionally provided.

[0103] When the column 1 is folded over to the top of the column structure 2 , the arm support structure 3 can be moved from the column 1 down to the column structure 2 ; or moved from the column structure 2 up to the column 1 .

[0104] As a preferred embodiment, this embodiment further includes a pushing device 6,

[0105] The first type: the pushing device is used to drive the column to tilt or descend;

[0106] The second type: the pushing device is used to drive the column to switch between the tilting and vertical states;

[0107] The second type: the pushing device is used to drive the column to be vertical or raised; or

[0108] The fourth type: the pushing device is used to drive the column to switch between the lowering and raising states.

[0109] As a preferred implementation, in the first embodiment of this invention, the pushing device adopts any one of a hydraulic push rod, an electric push rod, or a pneumatic push rod; or

[0110] The second type: the pushing device adopts a push rod, and the push rod adopts any one of hydraulic, electric, electrical or pneumatic power to provide power drive to directly or indirectly push the push rod to operate.

[0111] It should also be added that, in this embodiment, the column 1 and the column structure 2 can be rotatably connected via a rotating member 12 (or a hinged member), and a pushing mechanism (such as a hydraulic push rod) can be used to pull or push the column 1 to be vertical (or raised), tilted (or lowered), or switched between the vertical (or raised) and tilted (or lowered) states.

[0112] As a preferred implementation, this embodiment further includes a moving device 7, which is used to drive the wrist-arm supporting structure 3 to move.

[0113] In this embodiment, the moving device 7 drives the arm support structure 3 to rise or fall, which is now explained in two aspects: wherein the falling process is:

[0114] The first type: the moving device 7 is used to drive the arm support structure 3 to descend from the height-variable guide structure 4 and then detach from the height-variable guide structure 4;

[0115] The second method is: the moving device 7 is used to drive the arm support structure 3 to descend from the height-variable guide structure 4 and then dock on the bearing structure; or

[0116] The third type: the moving device 7 is used to drive the arm support structure 3 to descend from the height-variable guide structure 4 and then enter the separately provided guide structure 41.

[0117] The rising process is:

[0118] The first type: the moving device 7 is used to drive the arm support structure 3 from a suspended state to the height-variable guide structure 4;

[0119] The second method: the moving device 7 is used to drive the arm support structure 3 to rise from the bearing structure into the height-variable guide structure 4; or

[0120] The third type: the moving device 7 is used to drive the wrist-arm supporting structure 3 to rise from the separately provided guide structure 41 and then enter the height-variable guide structure 4.

[0121] like Figure 3 As shown, it should be noted that the height-variable guide structure 4 in this embodiment includes any one of a slide, a slide rail, a slide groove, a track or a limit frame, and the moving device 7 drives the arm support structure 3 to move in the slide, the slide rail, the slide groove, the track or the limit frame.

[0122] As a key part of this embodiment, this embodiment also includes a driving mechanism, which is used to drive the moving device 7 to move.

[0123] like Figure 1 and Figure 2 As shown, the driving mechanism includes a rack 8 provided on the column 1 and / or column structure 2; and a driving motor 9, which drives the moving device 7 to move on the column 1 and / or column structure 2 via the rack 8. The driving motor 9 is provided on the moving device 7, and the output shaft of the driving motor 9 is engaged with the rack 8 via a gear.

[0124] For additional information, please refer to Figures 1 to 3 As shown, in this embodiment, the moving device 7 is installed on the height-variable guide structure 4. Here, the height-variable guide structure 4 includes a structure capable of sliding, such as Figure 3 As shown, a height-variable guide structure 4 is shown, in which a guide bar is provided on the column 1, and the extended edge of the movable device 7 is buckled on the guide bar. A rack 8 is provided on the column 1, and at least one rack 8 is provided, or two racks can be provided to form a pair; the rack 8 can be installed in the middle part of the column 1, or can be installed on the outside of the column 1; a gear is installed on the output shaft of the drive motor 9, and when the drive motor 9 is actuated, the drive gear rotates to move up and down along the rack 8.

[0125] It should be noted that a column structure 2 is also provided in this embodiment, and a rack 8 is also provided on the column structure 2. In this way, after the arm support structure 3 is lowered from the column 1, it can be further lowered to the column structure 2 through the rack 8 on the column structure 2; when the drive motor 9 receives the travel position signal sent by the induction device (which can be a travel switch), it stops actuating. After the arm support structure 3 is docked on the column structure 2, the column 1 located at a high position is driven to make room for the space above the railway side. At this point, the conductor 5, the arm support structure 3 and the column 1 are all sunk and hidden, and the height after the descent can be at least lower than the height of the roof of the freight train. Of course, it can also be further lowered below the ground as needed. At this time, the mobile contact network is powered off, and lifting equipment can be used to load and unload cargo on the freight train.

[0126] When the freight train leaves the loading and unloading yard after loading and unloading, column 1 is driven upright (or raised). Drive motor 9 is activated, driving arm support structure 3 from column structure 2 onto column 1 and further upward. Arm support structure 3 then rotates to its working position, energizing the moving catenary. The freight train raises its pantograph, draws power, and can then depart.

[0127] It is worth mentioning the description of the working and non-working positions of the arm support structure 3. The working position of the arm support structure 3 refers to the conductor 5 being above the railroad, while the non-working position refers to the conductor 5 being located to the side of the railroad. The arm support structure 3 can be driven between the working and non-working positions by attaching a weight to one end of the conductor 5 and a traction motor to the other end.

[0128] In this embodiment, the arm support structure 3 can be rotated to the non-operating position before it is lowered; or it can be rotated to the non-operating position after it is lowered. The device provided in this embodiment is feasible. If there are no freight trains on the railway, the arm support structure 3 can be lowered before rotating to the non-operating position. If there are freight trains, the arm support structure 3 can be rotated to the non-operating position before it is lowered. Alternatively, the arm support structure 3 can be rotated to the non-operating position while it is lowered.

[0129] like Figure 4 and Figure 5 As shown, as a preferred embodiment, another driving method is also provided, the driving mechanism includes a pull rope 10; and also includes a winch 11, and the winch 11 is actuated by pulling the moving device 7 through the pull rope 10 to move.

[0130] like Figure 4 and Figure 5 As shown, a steering wheel 13 is provided near the top of the column 1. One end of the pull rope 10 acts on the winch. The free end (the other end) of the pull rope 10 first passes over the steering wheel 13 and then acts on the moving device 7. The winch 11 retracts or extends the pull rope 10 to drive the moving device 7 to move back and forth. When the winch 11 reels the line, the moving device 7 moves upward, and when the winch 11 pays out the line, the moving device 7 descends.

[0131] This embodiment further includes a sensing device (not shown in the figure), which is used to sense the travel position of the moving device 7 and control the driving mechanism to start or stop through the sensing signal.

[0132] A second aspect of this embodiment provides a mobile contact network, in which the above-mentioned folding sinking support device is adopted.

[0133] like Figure 6 As shown, a third aspect of this embodiment provides a method for operating a sinking mobile contact network. The mobile contact network in the operating method adopts the above-mentioned mobile contact network, or the mobile contact network in the operating method adopts the above-mentioned folding sinking support device. The operating method is as follows:

[0134] How to descend:

[0135] The arm support structure 3 descends along the height-variable guide structure 4, driving the conductor 5 to descend;

[0136] The height of the conductor 5 after being driven down by the arm support structure 3 can be at least lower than the height of the roof of the freight train;

[0137] After the cantilever support structure 3 descends, the height-variable guide structure 4 is driven to flip over and is in a dumping (or descending) state; or
