Description

Technical Field

[0001] The invention belongs to the field of electrified railway mobile contact network, and specifically relates to an extendable support device, a mobile contact network and an operation method. Background Art

[0002] With the advancement of electrified traction on railways, electric locomotives have replaced diesel locomotives on China's main railway lines. Electrification is also being implemented on freight loading and unloading lines or during warehousing and maintenance. Existing technologies use flexible, movable catenary systems. A motor directly pulls the load-bearing cables on one side of the flexible catenary, shifting the contact wires toward the rails. However, this method suffers from insufficient traction and unstable operation for long-distance moving catenary systems with an entire anchor section. Because it uses only a single weight, the movable catenary length generally does not exceed 800 meters.

[0003] A 10,000-ton heavy-haul train is an extra-long, heavy-duty freight train pulled by two or more locomotives. Its characteristics include high vehicle load capacity and a large number of train cars. According to current railway technical regulations, the effective arrival and departure track length at stations for 5,000-ton heavy-haul trains is 1,050 meters. For 10,000-ton heavy-haul trains on coal-dedicated lines, the effective arrival and departure track length at some stations is 1,700 meters. These trains include unit heavy-haul trains, combined heavy-haul trains, and complete trainset heavy-haul trains.

[0004] For long-distance, heavy-load trains, such as 1,400-1,700-meter, 10,000-ton heavy-load trains, shunting with diesel locomotives requires multiple cars to be decoupled. Existing technology is expensive, requiring diesel cars to be rented and parked at loading and unloading points. When the electric traction vehicle arrives at the loading and unloading point, the diesel and electric traction vehicles need to be swapped, which is extremely inefficient. To be able to swap traction vehicles, new parking lines and conversions are also required, increasing investment. The key point is that current diesel locomotives lack high-power locomotives and cannot tow heavy-load trains. Existing flexible contact network technologies, including those currently in practical application and those in prior patent applications, do not have flexible, mobile contact networks that can meet the requirements of 10,000-ton train cargo loading and unloading lines or in-warehouse maintenance.

[0005] The contact wires and load-bearing cables in the existing contact network cannot be completely moved to the side of the railway. In some cases, the columns of the mobile contact network are relatively close to the tracks, and the mobile contact network is moved to a non-working position, close to the train cars. When loading and unloading goods, it is easy to touch the load-bearing cables and / or contact wires on the mobile contact network.

[0006] On the other hand, existing mobile contact networks are basically used on straight rails. Due to limitations such as site conditions, existing mobile contact networks cannot be applied to curved rails. Summary of the Invention

[0007] In view of this, the purpose of the present invention is to overcome the shortcomings of the existing related technologies and provide a mobile contact network that can effectively meet the train loading and unloading operations in freight stations, so as to effectively solve the problem in the existing technology that the contact wire and the load-bearing cable cannot be fully moved to the side of the railway and solve the problem that the existing mobile contact network cannot be applied to curved rails.

[0066] The invention has the following beneficial effects:

[0067] 1. The invention directly changes the traditional inherent solution by movably placing the support structure on the support structure. When the support structure is in the working position, at least two points can be found on the support structure, and the line connecting these two points is marked as the first auxiliary line. When the support structure is in the non-working position, the line connecting two points at the same position on the support structure is marked as the second auxiliary line. The second auxiliary line is parallel to the first auxiliary line and / or is an extension of the first auxiliary line. This method can be used to move the conductor to the working position or the non-working position, or to switch between the working and non-working positions, effectively freeing up space for the railway system.

[0068] 2. Traditionally, the supporting device is generally rotatably mounted on the column and can be rotated under any driving force. The arm structure (also called the supporting structure) is used to drive the load-bearing cable and the contact line to move to the working position or the non-working position. However, the problem with this method is that all the arm structures in the mobile contact network need to rotate together. The existing problem is that after the outermost supporting device is rotated into place, the arm cannot be rotated into place. In this case, the load-bearing cable and the contact line cannot be completely moved out from above the rail and moved to the loading and unloading operation. In this solution, the supporting structure on each column uses a separate driving mechanism to move it out or retract it, which effectively solves the problem that the arm structure in the mobile contact network in the prior art cannot be put into place.

[0069] 3. The existing technology uses a drive mechanism at both ends of the mobile contact network to pull the load-bearing cables and contact wires to drive the entire arm to rotate to the side of the railway or above the railway. If the rotation fails, it is not suitable for curved railway tracks. The mobile contact network provided by the present invention provides a corresponding drive mechanism on each column. If the railway track is curved, the entire system composed of several extendable support devices is arranged at intervals on the side of the railway in a curved shape similar to the railway track.

[0070] 4. The direct-push arm support structure contact network provided by the invention can effectively meet the mobile contact line requirements of train loading and unloading operations in freight stations, thereby effectively solving the problem of easily hitting the load-bearing cables and / or contact lines on the mobile contact network in the prior art.

[0081] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, like numbers in different figures represent the same 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 invention. Rather, they are merely examples of devices consistent with certain aspects of the invention, as detailed in the appended claims.

[0082] like Figure 1 and Figure 2 As shown, the first part of the present invention provides a protruding support device, which is applied to the field of mobile contact network. The protruding support device includes a driving mechanism 1, a supporting structure 2 and a conductor 3, wherein

[0083] The conductor 3 is directly or indirectly arranged on the support structure 2;

[0084] The driving mechanism 1 is used to drive the support structure 2 to move, thereby driving the conductor 3 to move to the working position or to the non-working position, or to drive the conductor 3 to switch between the working position and the non-working position;

[0085] When the support structure 2 is in the working position, at least two points can be found on the support structure 2, and the line between the two points is marked as the first auxiliary line; when the support structure 2 is in the non-working position, the line between the two points at the same position on the support structure 2 is marked as the second auxiliary line;

[0086] The second auxiliary line is substantially parallel to the first auxiliary line, and / or

[0087] The second auxiliary line is substantially on an extension line of the first auxiliary line.

[0088] like Figure 3 and Figure 4 As shown, as an example, in Figure 1 In the support structure, three points A, B and C are marked. Figure 2 In the middle support structure, three points A1, B1 and C1 are marked at the same position;

[0089] like Figure 3 As shown, when in the working position, A and B are connected to form a first auxiliary line, and when in the non-working position, A1 and B1 are connected to form a second auxiliary line. The supporting structure moves from the working position to the non-working position, and the supporting structure basically retracts along the horizontal direction. The second auxiliary line is basically on the extension line of the first auxiliary line.

[0090] like Figure 4 As shown, in the working position, connections A and C form a first auxiliary line, and in the non-working position, connections A1 and C1 form a second auxiliary line. The support structure moves from the working position to the non-working position, and the support structure basically retracts in the horizontal direction. The second auxiliary line is basically parallel to the first auxiliary line.

[0091] This embodiment further includes a column 4, and during the process in which the supporting structure 2 drives the conductor 3 to move, at least a portion of the main body of the supporting structure 2 can move in space over one side or both sides of the column 4; or

[0092] During the process of the supporting structure 2 driving the conductor 3 to move, at least a portion of the main body of the supporting structure 2 can move from one side of the pillar 4 to the other side opposite to the pillar 4 .

[0093] It should be emphasized here that: the working position is the guiding element 3 (the load-bearing cable 31 and / or the contact wire 32 are located above the railway, and the pantograph of the freight train can be raised to obtain electricity; the non-working position is the guiding element 3 located on the side of the railway, leaving space above the railway for cargo loading and unloading or train maintenance operations, etc.).

[0094] In a traditional mobile contact network, the support structure 2 (also called a rotating arm) is rotatably mounted on the column 4. The rotating arm can swing left and right or up and down to drive the load-bearing cable 31 and the contact line 32 to rotate to the working position or the non-working position. In this embodiment, a new driving method is proposed, which drives the load-bearing cable 31 and the contact line 32 to rotate between the working position or the non-working position by moving the support structure 2 itself. An important feature of the movement here is that the support structure 2 itself can move over one side or both sides of the column 4 during the movement, or at least part of the main body of the support structure 2 can move from one side of the column 4 to the other side opposite to the column 4. The existing rotating arm is fixed or rotationally fixed to the column 4 at one end, and the rotating arm swings left and right or up and down relative to the column 4. It does not generate movement relative to the column 4. In other words, it does not enable at least part of the main body of the support structure 2 to move spatially over one side or both sides of the column 4 during the movement; or

[0095] During the movement, the supporting structure 2 does not move the conductor 3 , and at least a portion of the supporting structure 2 can move from one side of the column 4 to the other side opposite to the column 4 .

[0096] As a preferred embodiment, the driving mechanism 1 in this embodiment drives the supporting structure 2 to move and drives the conductor 3 to move away from the column 4 to the working position; or, the driving mechanism 1 drives the supporting structure 2 to move and drives the conductor 3 to move close to the column 4 to the non-working position.

[0097] It should be noted that, in the specific implementation, there is no specific limitation on the angle along which the support structure 2 is pushed out. In the present invention, it is only necessary to ensure that the support structure 2 is moved and pushed out to drive the conductor 3 to the working position, or moved and recovered to drive the conductor 3 to the non-working position.

[0098] A preferred method provided in this embodiment is: the support structure 2 extends in a basically horizontal direction to drive the conductor 3 to move away from the column 4 to the working position; or, the support structure 2 retracts in a basically horizontal direction to drive the conductor 3 to move closer to the column 4 to the non-working position.

[0099] Regarding the driving mechanism 1, as a supporting device of the supporting mechanism, the driving mechanism 1 is used to provide a driving force in a basically horizontal direction to the supporting structure 2. The driving mechanism 1 drives the supporting structure 2 to move and drives the conductor 3 to move away from the column 4 to the working position; or, the driving mechanism 1 drives the supporting structure 2 to move and drives the conductor 3 to move close to the column 4 to the non-working position.

[0100] It can be seen that the support structure 2 in this embodiment is pushed out in a substantially horizontal direction or pulled back in a horizontal direction, thereby driving the conductor 3 to move to the working position or to the non-working position or driving the conductor 3 to switch between the working position and the non-working position.

[0101] Here we need to explain why it is called the basic horizontal direction. The supporting structure 2 itself is about 3 meters long and has its own weight. The conductor 3 set at the free end of the supporting structure 2 will exert tension, and there are influences such as thermal expansion and contraction, construction errors, and slight deformation caused by long-term use. It is difficult to guarantee that it is absolutely horizontal, so the basic level is used.

[0102] Here we also need to make some additional explanations on the support structure 2 in the present invention. The support structure 2 in the present invention is used to support and drag the conductor 3, and needs to drive the conductor 3 to switch between the working position and the non-working position. The specific form of the support structure 2 can be various, for example, as shown in the present invention. Figure 1 and Figure 2 The one shown uses a moving rod, of course here Figure 1 and Figure 2The support structure 2 shown is only an example and is not a limitation to the specific support structure 2; some reinforcing rods are also added to the support structure 2 (to enhance stability), which are also part of the support structure 2; it can be understood that any component or structure attached to the support structure 2 that can be driven by the driving mechanism 1 to move together or move along with it can be understood as a part of the support structure 2 and included in the support structure 2 defined in the present invention.

[0103] The supporting structure 2 shown in the above embodiment is moved in a horizontal direction or substantially horizontally to be pushed out or moved to be pulled back. In fact, the supporting structure 2 can also be arranged tilted.

[0104] For example, in this embodiment, the support structure 2 and the column 4 have a preset angle in space, and the support structure 2 is pushed out or pulled back diagonally upward or downward, thereby driving the conductor 3 to move to the working position or to the non-working position or driving the conductor 3 to switch between the working position and the non-working position.

[0105] For example, the support structure 2 is directly or indirectly mounted on the column 4 in an inclined manner. When the support structure 2 is moved and pushed out (pushed out or pulled back diagonally upward or downward), the support structure 2 and the column 4 have a certain angle in space (preferably 0 to 60 degrees, and other angles or angles exceeding 60 degrees can also be selected according to the on-site installation conditions). As long as the support structure 2 drives the conductor 3 to be pushed out, the pantograph of the freight train located above the railway can draw power.

[0106] What are the benefits of doing this? It facilitates freight loading and unloading. Freight stations generally use gantry cranes or forklifts and other lifting and unloading tools. Since the mobile contact network is located on one side of the railway, the current practice is to use a forklift on the other side of the railway for loading and unloading operations. If the structure described above in this embodiment is adopted, the height of the column 4 can be set to be basically flush with or lower than the height of the freight train, and the support structure 2 is installed on the column 4 so that the support structure 2 can be pushed out or extended from the upper side to the working position. At this time, the freight train can enter or exit the freight station. When the train stops, the support structure 2 is moved and recovered. At this time, it can at least meet the requirement that the support structure 2 is at least lower than the highest point of the freight train or lower than the upper surface of the freight train when it is in the non-working position. At this time, the upper space can be effectively vacated, and a gantry crane or a forklift can be used to carry out loading and unloading operations from both sides of the railway, greatly improving the loading and unloading efficiency. However, there is no such method in the existing mobile contact network. It is an innovative solution independently developed by the applicant.

[0107] The driving mechanism 1 in this embodiment includes any one or a combination of a motor, an electric push rod, a hydraulic push rod, a pneumatic push rod, a chain drive and a gear drive;

[0108] Any one or a combination of the motor, the electric push rod, the hydraulic push rod, the pneumatic push rod, the chain drive and the gear drive is used to directly or indirectly provide driving force and act on the support structure 2, thereby driving the support structure 2 to move.

[0109] In this embodiment Figure 1 and Figure 2 FIG. 5 shows a driving method using a push rod to drive the support structure 2 to move.

[0110] As a preferred implementation, in this embodiment, the driving mechanism 1 is directly or indirectly provided on the column 4 , and the supporting structure 2 is directly or indirectly provided on the driving mechanism 1 .

[0111] It is important to note here that in order to resolve the lateral pull on the support structure 2 caused by the thermal expansion and contraction of the conductor 3 and the tension at both ends of the conductor 3, if the lateral pull on the support structure 2 exceeds a certain force, it is easy to deform the support structure 2 or cause irreversible damage, affecting the service life of the mobile contact network. In this embodiment, a force-adjustable device is used to apply the force provided by both ends of the mobile contact network only to or mostly to the conductor 3. This requires the installation of a rotating mechanism on each column 4. The existence of the rotating mechanism is mainly to resolve the damage to the support structure 2 caused by the lateral tension. There are many factors that cause this, such as the thermal expansion and contraction of the conductor 3 and the installation and construction errors of the mobile contact network, which can easily lead to uneven lateral tension on the support structure 2 between the columns 4.

[0112] Therefore, this embodiment also includes a rotation mechanism, solution 1: the rotation mechanism is directly or indirectly provided on the column 4; the support structure 2 can be rotated by the rotation mechanism. Or,

[0113] Solution 2: The rotating mechanism is directly or indirectly provided on the driving mechanism 1; the supporting structure 2 can be rotated through the rotating mechanism.

[0114] It should be noted that when the conductor 3 is in the working position, it only needs the pantograph of the freight train to be lifted to draw electricity. The pantograph itself has a power-drawing range of a certain width. Therefore, when in the working position, the support structure 2 is not required to be perpendicular to the railway in space. The support mechanism is allowed to have a slight left and right deviation that is not completely perpendicular to the railway in order to balance the tension of the conductor 3.

[0115] The above embodiment is an example of directly or indirectly mounting the support structure 2 on the drive mechanism 1. This embodiment also provides another preferred implementation, that is, this embodiment further includes a supporting structure directly or indirectly provided on the column 4, the supporting structure being used to support the support structure 2 at a preset height.

[0116] A supporting structure is added, and this embodiment also includes a rotation mechanism. Option 1: the supporting structure 2 is directly or indirectly arranged on the supporting structure through the rotation mechanism, and the supporting structure 2 can be rotated by the rotation mechanism, and the driving mechanism 1 is used to drive the supporting structure 2 to switch between the working position and the non-working position; or

[0117] Solution 2: The driving mechanism 1 is directly or indirectly arranged on the supporting structure through the rotating mechanism, and the supporting structure 2 is directly or indirectly arranged on the driving structure. The driving mechanism 1 can be rotated through the rotating mechanism.

[0118] Solutions 1 and 2 use a rotating mechanism, the functions of which are the same as those described above or described in detail, and will not be repeated here.

[0119] To further optimize the above embodiment, this embodiment also includes a limiting structure; the limiting structure includes any one or a combination of two or more of a limiting frame, a slide, a chute, a slide rail, and a track. The driving mechanism 1 drives the support structure 2 to move back and forth within the limiting frame, the slide, the chute, the slide rail, or the track to achieve switching between the working position and the non-working position. The limiting structure in this embodiment is used primarily for convenience and to improve the stability of the support structure 2 during movement.

[0120] As a preferred embodiment, the drive mechanism 1 in this embodiment includes a rack drive mechanism 1, which drives the support structure 2 to move. It should be noted that the rack drive mechanism 1 can be a gear mounted on the output shaft of a motor, meshing with the gear and the rack, and the motor drives the support structure 2 to move out or retract. It should be understood that this is only one embodiment of the rack mechanism and does not specifically limit the rack mechanism in the claims, but is merely an explanation.

[0121] or

[0122] The driving mechanism 1 includes a chain mechanism, which is used to drive the support structure 2 to move. As an additional explanation, the chain mechanism here can adopt a motor, a driving sprocket, a driven sprocket and a chain. The chain is wound around the driving sprocket and the driven sprocket. The motor drives the driving sprocket to rotate and drive the chain to move. By directly or indirectly connecting a part of the chain to the support structure 2, the movement of the chain can drive the movement of the support structure 2. This is just an embodiment of the chain mechanism. It should be understood that it is not a specific limitation of the chain mechanism in the claims, but only an explanation.

[0123] As a preferred implementation, this embodiment further includes an insulator 5 , which is installed on the supporting structure 2 . The insulator 5 is used to electrically isolate the supporting structure 2 .

[0124] As a preferred implementation, this embodiment further includes a support member 6 , which is directly or indirectly mounted on the support structure 2 , and the conductor 3 is directly or indirectly disposed on the support member 6 .

[0125] On the other hand, this embodiment provides a mobile contact network; the mobile contact network adopts the above-mentioned direct-push support structure 2, the conductor 3 includes a load-bearing cable 31 and / or a contact wire 32, and also includes a tension providing structure and / or a tensioning device 8 for providing a tensioning force for the conductor 3; the tension providing structure and / or the tensioning device 8 provide a tensioning force from both ends of the conductor 3.

[0126] It should be noted that, in this embodiment, the installation structure for providing tensioning force from both ends of the conductor 3 adopts at least one of the following or a combination thereof:

[0127] The first type comprises a tension providing structure and a tensioning device 8, wherein one end of the load-bearing cable 31 and / or the contact wire 32 is directly or indirectly fixed to the tensioning device 8, and the force provided by the tension providing structure acts directly or indirectly on the other end of the load-bearing cable 31 and / or the contact wire 32;

[0128] The second type: when two tension providing structures are provided, including a first tension providing structure and a second tension providing structure; the force provided by the first tension providing structure acts directly or indirectly on one end of the catenary cable 31 and / or the contact line 32, and the force provided by the second tension providing structure acts directly or indirectly on the other end of the catenary cable 31 and / or the contact line 32; or

[0129] The third type: Figure 5 and Figure 6As shown, when two tensioning devices 8 are provided, they include a first tensioning device 8 and a second tensioning device 8, one end of the load-bearing cable 31 and / or the contact wire 32 is directly or indirectly provided on the first tensioning device, and the other end of the load-bearing cable 31 and / or the contact wire 32 is directly or indirectly provided on the second tensioning device, and the tensioning devices provide tensioning force to the conductor 3 from both ends.

[0130] As a preferred embodiment, the tension providing structure in the first and second embodiments of the present invention is a weight; the gravity force provided by the weight acts directly or indirectly on one end or both ends of the load-bearing cable 31 and / or the contact line 32;

[0131] The tensioning device in the first and third types is any one or more of a motor, a winch, a fixed part, a hydraulic tensioning device and a spring tensioning device;

[0133] It should be noted that, since the present mobile contact network adopts the method of supporting the structure 2 to move and push out the conductor 3 or to move and retract the conductor 3, the tension providing structure and / or tensioning device at both ends of the mobile contact network actually only needs to provide tensioning force. When the weight at one end of the mobile contact network provides gravity force to the load-bearing cable 31 and / or the contact line 32, the other end of the load-bearing cable 31 and / or the contact line 32 only needs to be fixed, and the weight can provide tension. At this time, the other end of the load-bearing cable 31 and / or the contact line 32 can be directly fixed on a fixed part, such as a fixed part of the gantry 7. Of course, according to actual conditions, any one or more of the above-mentioned motors, winches, hydraulic tensioning devices and spring tensioning devices can also be set on the other end of the load-bearing cable 31 and / or the contact line 32.

[0134] In addition, in the process of the support structure 2 in this embodiment driving the conductor 3 to switch between the working position and the non-working position, the weight is driven to rise or fall, and the support structure 2 moves out and pulls up the weight provided at one end or both ends of the mobile contact network for providing gravity force; similarly, when the support structure 2 moves back, the weight provided at one end or both ends of the mobile contact network for providing gravity force will be lowered; or

[0135] like Figure 3 and Figure 4As shown in the figure, an example of a tensioning device being provided at both ends of a mobile contact network is shown. In the process in which the supporting structure 2 drives the conductor 3 to switch between the working position and the non-working position, the tensioning device drives the conductor 3 connected directly or indirectly to move between the working position and the non-working position; or

[0136] As another preferred embodiment, relevant drawings are not shown in the present embodiment. In the process where the supporting structure 2 drives the conductor 3 to switch between the working position and the non-working position, the tensioning device can pay out or reel in the conductor 3.

[0137] As a preferred embodiment, this embodiment further includes a tension sensor, which is used to detect the tension of the conductor 3 and control the increase or decrease of the tension provided by the tensioning device to the conductor 3. The tension sensor in this embodiment can be set in the tension providing structure and / or the tensioning device, for example, when both ends of the supporting cable and the contact wire are tensioning devices, such as Figure 5 and Figure 6 As shown, a tension sensor is installed in the tensioning device to measure the tension of the load-bearing cable and / or the contact wire. The load-bearing cable and / or the contact wire is tightened or loosened by the tensioning device.
