Abstract
Description
Technical Field
[0001] This invention belongs to the field of mobile contact network for electrified railways, specifically relating to a mobile contact network and its operation method for eliminating construction errors. Background Technology
[0002] With the advancement of railway electrification, electric locomotives have replaced diesel locomotives in the transportation of China's main railway lines. Electrification is also implemented on freight loading and unloading lines or for maintenance in warehouses. Currently, rigid movable contact networks are used, but existing rigid movable contact network systems are extremely expensive, have complex structures, are inconvenient to install, have high requirements for line operating conditions, and have poor structural reliability. They use electric motors to drive rotating brackets to rotate, thereby moving the entire movable contact network section to one side of the rail. In this method, the busbar is installed as a whole at the end of the rotating bracket, and there are many electric motors, making it difficult to control the synchronization of the electric motors or electric push rods.
[0003] With the innovation of electrified railway technology, those skilled in the art are constantly innovating and upgrading the technology to provide electrified mobile contact networks that can meet the needs of cargo loading and unloading lines or warehouse maintenance. Summary of the Invention
[0004] Existing technologies also include flexible, movable contact wires, where a motor directly drags the catenary cable from one side of the flexible contact wire, moving the contact wire to the side of the rail. Other technologies use mechanically driven cantilever arms to raise the contact wire. However, even with raising, the contact wire cannot be completely moved to the outside of the railway, still affecting the loading and unloading of large goods. If a rotating cantilever arm is used to swing the contact wire left and right to the railway side, it still has the drawback of not being able to swing it completely to the railway side. These technologies have the following shortcomings:
[0005] 1. Thermal expansion and contraction will inevitably cause the contact wire and catenary to extend, potentially leading to pantograph-catenary faults (faults in the train's pantograph and contact wire). This could result in serious safety accidents such as the compensation device adjusting the wire tension falling to the ground, the cantilever arm shifting, or the positioner detaching. If the contact wire becomes entangled in the train's pantograph (a horizontal plate raised high above the locomotive) due to slack, it could pull down the contact wire pole, causing the locomotive to derail and the carriages to tip over, with extremely serious consequences.
[0006] 2. The catenary and contact wire are fixedly installed on the rotating cantilever arm. There are construction errors in the spacing between the columns, the verticality, and the tension of the catenary and contact wire between the cantilever arms.
[0007] According to existing major railway technical policies, for 5000t heavy-haul freight trains, the effective length of arrival and departure tracks at stations is 1050m. For 10000t heavy-haul freight trains operating on dedicated coal transport lines, the effective length of arrival and departure tracks at some stations is 1700m. For such long-distance heavy-haul trains, such as 1400m to 1700m heavy-haul trains, due to the effects of thermal expansion and contraction and construction errors, the mobile contact wire may not rotate properly when it is rotated above or to the side of the railway.
[0008] The current practice is to install a weight at one end of the mobile contact wire and a dragging mechanism at the other end. The dragging mechanism pulls the catenary and / or contact wire to move the contact wire from one side of the rail to above the rail or from above the rail to one side of the rail.
[0009] Through the applicant's continuous research and practice, the above-mentioned scheme can effectively drive the catenary and / or contact wire to move to one side or above the rail. However, a new problem arises in actual use: The scheme is designed so that the cantilever arm rotates to the right to move the contact wire and catenary to one side of the rail. Due to the thermal expansion and contraction characteristics of the contact wire and catenary, when the rightmost cantilever arm moves to one side of the rail (the cantilever arm is nearly parallel to the rail, which can be understood as completely swinging to one side to make room above the railway), the other cantilever arms do not completely rotate to one side of the rail (this can be understood as at least one cantilever arm in the entire contact network not completely swinging to the railway once; for long-distance contact networks, there are cases where the swing stops when it reaches above the railway side, because the rightmost cantilever arm...). (The rightmost wrist arm has already swung into position). The further the wrist arm is from the rightmost wrist arm, the smaller its offset. That is, when the rightmost wrist arm stops rotating, the other wrist arms have not yet rotated into position. This is especially true for long-distance heavy-haul train mobile contact networks of about 1600 meters. When the rightmost wrist arm stops rotating after it has reached its position, the other wrist arms that are far from the rightmost wrist arm are still not rotated into position, or even above the side of the rail. This will affect the loading and unloading operations of large freight yards, containers and other goods. In addition, due to the incomplete rotation, there may be poor contact of the pantograph for power collection or no contact at all, which will affect the entry or exit of freight trains.
[0010] The applicant has included the defects in the description of the invention to illustrate that the formulation of the technical problem is also part of the creation of this invention, and there is no solution to the technical problem in the current public technology.
[0011] The existing flexible contact network technology, including the technology currently in practical application and the prior patent application documents, does not disclose this defect and related solutions. The applicant is confident that it is the first in the industry to provide a solution to this technical defect. If this defect cannot be solved, it will directly affect the operation of the mobile contact network and cause safety hazards in the commercial application of the mobile contact network. Therefore, the applicant has conducted research and provided a complete solution and applied for intellectual property protection for it.
[0012] To achieve the above objectives, the applicant provides a technical solution that effectively addresses the shortcomings of existing mobile overhead contact systems in terms of the movement of the catenary and contact wire. This solution is lower in cost, more reliable in operation, less affected by weather, and simpler to maintain compared to rigid overhead contact systems. Furthermore, the overhead contact system provided in this application overcomes the shortcomings of the original towing method of movement by using gravity-assisted movement. This effective improvement on the existing overhead contact system allows for integrated movement over longer distances (1600m-1700m). Besides meeting the needs of existing freight train loading and unloading lines or depot maintenance, it can also be effectively applied to heavy-haul trains such as those with a capacity of 10,000 tons.
[0013] To achieve the above objectives, the first aspect of this invention provides a movable contact network to eliminate construction errors. The traditional method involves fixing the catenary and contact wire to a rotating bracket, and then moving them from one side of the rail to above or vice versa as the bracket rotates. Through continuous research and innovation, the applicant has proposed a revolutionary solution: the catenary and contact wire are not fixed to the rotating bracket. This allows them to rotate without being affected by construction errors or thermal expansion and contraction.
[0014] The applicant provides two technical approaches. The first is to allow the catenary and / or contact wire to move back and forth directly on the rotating arm. This method also eliminates the need for the traditional "catenary clamp and contact wire contact seat". The second is to slide the catenary and / or contact wire on the rotating arm through a slider or similar sliding mechanism. As for the driving method of the rotating arm and the dragging mechanism at both ends of the catenary and contact wire, these are not the focus of this patent. The patent assumes that the catenary and contact wire can be pulled to the left or right, that is, the catenary and contact wire can be pulled from one side of the rail to above the rail or from above the rail to one side of the rail.
[0015] To solve the above-mentioned technical problems, the present invention provides a mobile contact network for eliminating construction errors, wherein the contact network is provided with a plurality of support devices and further includes a catenary and / or a contact wire;
[0016] Using the supporting device as the radius of rotation, several supporting devices rotate from the working position to the non-working position or from the non-working position to the working position; among them
[0017] In at least one support device, during the process of rotating from a working position to a non-working position or from a non-working position to a working position, the maximum horizontal movement distance of the catenary and / or contact wire in the horizontal direction can be greater than the horizontal rotation distance of the support device.
[0018] Furthermore, the power supply can be provided in any of the following ways:
[0019] Method 1: Includes a dragging mechanism, which is used to pull the catenary and / or contact wire on several support devices;
[0020] Method 2: Includes at least one rotating mechanism for driving the support device to rotate, the rotating mechanism driving the support device to rotate and thus moving the catenary and / or contact wire; or
[0021] Method 3: Includes a dragging mechanism and a rotating mechanism, wherein the dragging mechanism drags the catenary and / or contact wire to move, and the rotating mechanism drives the support device to rotate.
[0022] In this invention, the catenary and / or contact wire can be pulled by a dragging mechanism or moved by rotating a support device.
[0023] Regardless of whether the first or second approach provided by the applicant is adopted, within a quarter circle, which can be understood as rotating from the working position to the non-working position or from the non-working position to the working position, the maximum horizontal movement distance of the catenary and / or contact wire in the horizontal direction can be greater than or equal to the horizontal rotation distance of the support device (the length of the rotation radius of the support device).
[0024] Furthermore, when at least one of the supporting devices in the mobile contact network stops rotating, the catenary and / or contact wire can be pulled to move further on several supporting devices.
[0025] Furthermore, the horizontal distance that the catenary and / or contact wire moves in the horizontal direction is greater than or equal to the horizontal distance that the support device rotates.

[0065] The operation method for flexible mobile overhead contact lines in large freight yards and container yards is as follows:
[0066] The catenary wire and / or contact wire are installed on several support devices of the contact network;
[0067] The catenary and / or contact wire are pulled and moved, causing several support devices to rotate from the working position to the non-working position or from the non-working position to the working position; or the rotation of several support devices causes the catenary and / or contact wire to rotate from the working position to the non-working position or from the non-working position to the working position.
[0068] This ensures that in at least one support device, the maximum horizontal movement distance of the catenary and / or contact wire is greater than or equal to the horizontal rotation distance of the support device.
[0069] Furthermore, when at least one support device in the contact network stops rotating after rotating into position, the catenary and / or contact wire is pulled to move further on several support devices; the horizontal distance the catenary and / or contact wire moves in the horizontal direction is greater than or equal to the horizontal distance the support device rotates.
[0070] Furthermore, the force transmission mechanism is used to convert the force of the catenary and / or contact wire into a thrust or pull force, which is applied to the support device to push or pull several support devices to rotate further, thereby achieving stroke compensation.
[0071] The operation method for flexible mobile overhead contact lines in large freight yards and container yards is as follows:
[0072] The catenary wire and / or contact wire are installed on several support devices of the contact network;
[0073] The catenary and / or contact wire slides in the horizontal direction;
[0074] The force transmission structure applies the tensile or pushing force generated during the sliding process of the catenary and / or contact wire to the support device or the supporting structure, thereby pulling or pushing the support device to rotate.
[0075] In at least one support device, the maximum horizontal movement distance of the catenary and / or contact wire can be greater than or equal to the horizontal rotation distance of the support device;
[0076] The load-bearing cable and / or contact wire are pulled, thereby causing several support devices to rotate from the working position to the second position or from the second position to the working position.
[0077] The operation method for flexible mobile overhead contact lines in large freight yards and container yards is as follows:
[0078] The catenary and / or contact wire are installed along the length of several support devices on the catenary.
[0079] The catenary and / or contact wire slides in the horizontal direction;
[0080] The force transmission mechanism applies the tensile or pushing force generated during the movement of the clamping mechanism on the catenary and / or contact line to the support device or supporting structure, thereby pulling or pushing the support device to rotate.
[0081] In at least one support device, the maximum horizontal movement distance of the catenary and / or contact wire is greater than or equal to the horizontal rotation distance of the support device;
[0082] The catenary and / or contact wire is pulled, thereby causing several support devices to rotate from the working position to the second position or from the second position to the working position; or the rotation of several support devices causes the catenary and / or contact wire to rotate from the working position to the non-working position or from the non-working position to the working position.
[0083] The operation method for flexible mobile overhead contact lines in large freight yards and container yards is as follows:
[0084] The catenary and / or contact wire are installed along the length of several support devices on the catenary.
[0085] Pull the catenary and / or contact wire to slide horizontally;
[0086] The force transmission mechanism applies the thrust or tension generated during the movement of the load-bearing cable and / or contact line or sliding mechanism to the support device or supporting structure, thereby pushing or pulling the support device to rotate.
[0087] In at least one support device, the maximum distance that the catenary and / or contact wire can be moved by being pulled is greater than or equal to the horizontal distance of rotation of the support device;
[0088] The catenary and / or contact wire is pulled, thereby causing several support devices to rotate from the working position to the second position or from the second position to the working position; or the rotation of several support devices causes the catenary and / or contact wire to rotate from the working position to the non-working position or from the non-working position to the working position.
[0089] Furthermore, after the outermost support device of the mobile contact network is in place and stops rotating, the catenary and / or the contact wire are further pulled, so that the entire catenary and / or contact wire moves on several support devices.
[0090] Furthermore, the catenary or contact wire is pulled further, thereby transmitting the tension of the catenary or contact wire to the support device, the supporting structure, or the sliding mechanism through the force transmission mechanism. This causes the support device to rotate further in the direction in which the catenary and / or contact wire is pulled, thus achieving stroke compensation.
[0091] Furthermore, the counterweight device is connected to at least one support device via a pull rope;
[0092] The counterweight device itself assists in pulling at least one support device to rotate to a non-working position.
[0093] When at least one support device rotates toward the working position, the counterweight device is lifted by the rotation of the support device; or
[0094] An external lifting mechanism is used to lift the counterweight device, and then several support devices rotate toward the working position.
[0095] The present invention has the following beneficial effects:
[0096] 1. The present invention directly changes the traditional solution, allowing the catenary to move relative to the support device; or the contact wire to move relative to the support device. The maximum horizontal movement distance of the catenary and / or contact wire in the horizontal direction is greater than the horizontal rotation distance of the corresponding support device, thus eliminating construction errors and the effects of thermal expansion and contraction.
[0097] 2. By employing a force transmission mechanism, the thrust or tension generated during the movement of the catenary and / or contact wire is applied to the support device, thereby pulling or pushing the support device to rotate. With this structural change, the support device is generally rotatably mounted on the column and can rotate under any pushing force. Therefore, by using a force transmission mechanism to push or pull the support device to rotate, even after the outermost support device has rotated into place, as long as the catenary and / or contact wire can be pulled further, the force transmission mechanism can push or pull the support device to rotate further. This can solve the problem of all support devices in the existing mobile contact network not being able to be positioned correctly.
[0098] 3. The flexible contact wire provided by this invention has more uniform stress distribution, shorter construction period, less impact from weather, temperature difference and other factors, can be widely used in various harsh environments, has a long service life, can be improved on the basis of existing contact wires, and has many advantages such as convenient installation and maintenance, and similar fixed contact wire structure.
[0099] 4. By using the contact line provided by this invention, heavy-haul trains with a capacity of 10,000 tons will no longer need to use diesel locomotives for shunting operations. This overcomes the traditional need for multiple cars to be separated, or even the inability to haul heavy-haul trains. It can effectively meet the needs of loading and unloading cargo lines or warehouse maintenance for trains with a capacity of 10,000 tons, improve work efficiency, and greatly save the cost of purchasing diesel locomotives and the existing labor costs for dispatching, maintaining and repairing diesel locomotives.

[0137] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses consistent with some aspects of the invention as detailed in the appended claims.
[0138] like Figure 1 As shown in the diagram, a traditional mobile catenary is designed so that the cantilever arm rotates to the right, moving the contact wire and catenary to one side of the rail (non-working position). Due to construction errors and the effects of thermal expansion and contraction on the contact wire and catenary, when the rightmost cantilever arm a moves to one side of the rail (the cantilever arm is nearly parallel to the rail, making room above the railway), the other cantilever arms (cantilever arms a to d) have not completely rotated to one side of the rail. (This can be understood as at least one cantilever arm in the entire catenary not having fully swung to the railway once. For long-distance catenary systems, there are cases where the swing stops when the arm reaches the side above the railway, because the rightmost cantilever arm has already swung into position.) The further the rotating arm is from the rightmost arm, the smaller its offset. That is, when the rightmost arm stops rotating, the other arms have not yet rotated to their positions. This is especially true for long-distance heavy-haul trains with mobile overhead contact lines of about 1600 meters. When the rightmost arm stops rotating after it has reached its position, the other arms that are far from the rightmost arm are still not rotated to their positions, or even above the side of the rail. This will affect the loading and unloading operations of large freight yards, containers and other goods. In addition, due to the incomplete rotation, there may be poor contact or inability to make contact with the pantograph to obtain power, which will affect the entry or exit of freight trains.
[0139] like Figure 2 As shown, the present invention provides a mobile contact network for eliminating construction errors. The contact network is provided with a plurality of support devices and also includes a catenary and / or a contact wire.
[0140] Using the supporting device as the radius of rotation, several supporting devices rotate from the working position to the non-working position or from the non-working position to the working position; among them
[0141] In at least one support device, during the process of rotating from the working position to the non-working position or from the non-working position to the working position, the maximum horizontal movement distance (L1) of the catenary and / or contact wire in the horizontal direction can be greater than the horizontal rotation distance L2 of the corresponding support device.
[0142] It should be added that during the movement of the catenary and / or the contact wire, several supporting devices are pulled or pushed to rotate to the working position or non-working position.
[0143] The working position is as follows: the catenary and / or contact wire is located above the rail;
[0144] The non-working position is when the catenary and / or contact wire is located on one side of the rail.
[0145] Power is provided in any of the following ways:
[0146] Method 1: Includes a dragging mechanism, which is used to pull the catenary and / or contact wire on several support devices;
[0147] Method 2: Includes at least one rotating mechanism for driving the support device to rotate, the rotating mechanism driving the support device to rotate and thus moving the catenary and / or contact wire; or
[0148] Method 3: Includes a dragging mechanism and a rotating mechanism, wherein the dragging mechanism drags the catenary and / or contact wire to move, and the rotating mechanism drives the support device to rotate.
[0149] In a preferred embodiment, when at least one support device in the contact wire stops rotating, the catenary and / or contact wire can move further on several support devices.
[0150] The horizontal distance that the catenary and / or contact wire moves in the horizontal direction is greater than the horizontal distance that the support device rotates.
[0151] This embodiment also includes a force transmission mechanism, which is used to convert the force of further pulling the catenary and / or contact wire into a thrust or pull force to act on the support device, thereby pushing or pulling several support devices to rotate further to achieve stroke compensation.
[0152] In a preferred embodiment, when at least one support device in the contact wire (generally the outermost support device) stops rotating, the catenary and / or contact wire can further move on several support devices. The horizontal distance the catenary and / or contact wire moves in the horizontal direction is greater than or equal to the horizontal distance the support device rotates. Figure 2As shown, after the catenary and / or contact wire move from point A to point B, the horizontal distance L1 of the catenary and / or contact wire movement is greater than L2. Figure 2 As can be seen, at this time, through the external drag mechanism ( Figure 2 Not shown in the image, see [link / reference]. Figure 3 The dragging mechanism (as shown) is used to pull the catenary and / or contact wire on several support devices, so that the catenary and / or contact wire moves from point B to point B', and the total distance traveled by the catenary and / or contact wire in the horizontal direction is L2.
[0153] like Figure 4 As shown, the catenary and / or contact wire moves from point A to point A'. Since the catenary and / or contact wire is slidably mounted on the support device, there is a sliding amount relative to the support device during the movement. Therefore, it will move from point A to point A', and the horizontal distance it travels is L1. At this time, the corresponding horizontal distance the support device rotates is L2. That is to say, as long as the catenary and / or contact wire has a relative sliding amount relative to the support device during the movement, L1 will always be greater than L2 at any position during the rotation.
[0154] Of course, there can be at least one rotating mechanism for driving the support device to rotate, which drives the support device to rotate and causes the catenary and / or contact wire to move in a non-working swing direction.
[0155] To clarify: the purpose is to rotate the catenary, contact wire, and support device to the non-working position. This can be achieved by pulling the catenary and / or contact wire, which will cause the support device to rotate. Alternatively, a rotary motor can be used to drive the support device to rotate, which in turn will move the catenary and / or contact wire to the non-working position.
[0156] The most significant innovation of this overhead contact system is that the maximum horizontal movement distance of the catenary and / or contact wire in the horizontal direction can be greater than or equal to the rotation radius of the supporting device. In other words, it is applicable to supporting devices where the catenary and / or contact wire are not fixed in place. Figure 1 The catenary and contact wire shown are fixed to the cantilever arm. Any rotation of the cantilever arm or pulling of the catenary will cause the catenary to move a distance in the horizontal direction less than or equal to the rotation radius of the cantilever arm. Especially in long-distance mobile contact networks, due to construction errors and the effects of thermal expansion and contraction, such as in summer, when cantilever arm a rotates to its position and stops, cantilever arms c and d, which are farther away, cannot rotate to their positions.
[0157] In this patent, the entire load-bearing cable or contact wire is slidably mounted on several support devices. This not only overcomes the influence of construction errors, but also effectively reduces or ignores the influence of thermal expansion and contraction on the rotation of the support devices, regardless of whether it is winter or summer.
[0158] By this point, those skilled in the art should understand that when the catenary and / or contact wire can slide, the maximum horizontal movement distance of the catenary and / or contact wire in the horizontal direction can be greater than the horizontal rotation distance of the corresponding support device.
[0159] As a preferred embodiment, to better ensure that the supporting arm rotates to the non-working position when the load-bearing cable moves, this patent provides the following solutions:
[0160] The first type also includes a force transmission mechanism, which is used to convert the force of further pulling the catenary and / or contact wire into a thrust or pull force that directly or indirectly acts on the support device, thereby pushing or pulling several support devices to rotate further to achieve stroke compensation.
[0161] The second method involves installing a rotating mechanism, such as a rotating motor, at the base of at least one support device, i.e., where the support device connects to the column. This method can be used alone or in combination with the first method.
[0162] The third type also includes a counterweight device, which is connected to the support device via a rope; the counterweight device is used to assist the support device in rotating to a non-working position. This solution can be used alone or in combination with at least two of the first and second types.
[0163] like Figure 5 , Figure 6 and Figure 7 As shown, when the catenary and / or the contact wire slides directly on the support device, the support device includes a support structure, wherein;
[0164] One method for setting the catenary and / or contact wire is as follows:
[0165] The load-bearing cable 1 is capable of sliding within the supporting structure 7; and / or
[0166] The contact line is capable of sliding within the supporting structure;
[0167] or
[0168] The second method for setting up the catenary and / or contact wire is as follows:
[0169] The catenary cable is capable of sliding within the supporting structure; and / or
[0170] The contact line causes the supporting structure to slide on the support device.
[0171] In this invention, the catenary and / or contact wire are not fixed to the support device. The conventional approach is to fix the catenary and contact wire to a rotating arm, which then moves them by rotating the arm. Here, the rotating arm can be understood as a type of support device, rotatably mounted on a column. In this invention, the catenary can move relative to the support device; or the contact wire can move relative to the support device. Regarding electrical isolation, insulators can be installed on the support device to solve the problem.
[0172] It should be further explained that the supporting structure 7 in this embodiment mainly serves to support the catenary or contact wire. There are various implementation methods for the supporting structure, such as using a sliding head (e.g., Figure 5 and Figure 5A As shown), slip ring (such as Figure 6 , Figure 6A and Figure 6B As shown, where Figure 6B This is a schematic diagram of the structure where the catenary cable slides within the slip ring. The diagram shows the slip ring extended along its length to form a sleeve, as shown... Figure 6C As shown, both sliding rings and sleeves are types of support structures, and slip rings and sleeves fall within the protection scope of support structures. Groove structures (such as...) Figure 7 and Figure 7A As shown in the figure, the supporting structure only needs to be able to support the load-bearing cable.
[0173] The following is a supplementary explanation: This embodiment provides an implementation method in which the contact line drives the supporting structure to slide on the support device: as follows Figure 8 As shown, the contact line is held in place at both ends by the supporting structure, as... Figure 8 The position of point a in the diagram; the supporting device slides left and right on the sliding rod in the supporting structure 7, such as... Figure 8 The location of point b in the diagram.
[0174] In a preferred embodiment, this embodiment also includes a force transmission mechanism 9, which is used to directly or indirectly apply the thrust or tension generated during the movement of the load-bearing cable to the support device 3 or the supporting structure 7, thereby pulling or pushing the support device 7 to rotate; and / or
[0175] The force transmission mechanism is used to directly or indirectly apply the thrust or tension generated during the movement of the contact wire to the support device or supporting structure, thereby pulling or pushing the support device to rotate. The arrangement of the force transmission mechanism on the contact wire is the same as that on the catenary.
[0176] like Figures 9 to 12As shown, the force transmission mechanism in this embodiment includes an elastic mechanism. One end of the elastic mechanism is directly or indirectly connected to the load-bearing cable, and the other end of the elastic mechanism acts on the support device or the supporting structure. The load-bearing cable moves to compress or stretch the elastic mechanism, and the pushing or pulling force generated by the elastic mechanism acts directly or indirectly on the support device or the supporting structure, thereby pushing or pulling the support device to rotate.
[0177] It should be added that, Figure 9 The other end of the force transmission mechanism 9 acts on the supporting structure 7, and the moving force cable compresses the force transmission mechanism. The driving force generated by the force transmission mechanism 9 acts directly or indirectly on the supporting structure 7, thereby driving the support device to rotate.
[0178] Figure 10 and Figure 11 The other end of the elastic mechanism acts on the support device, and the moving force transmission mechanism of the load-bearing cable compresses the force transmission mechanism. The driving force generated by the force transmission mechanism acts directly or indirectly on the support device, thereby driving the support device to rotate.
[0179] like Figure 12 As shown, the other end of the elastic mechanism acts on the support device, the tension transmission mechanism of the moving load cable, and the tension force generated by the force transmission mechanism 9 acts directly or indirectly on the support device, thereby pulling the support device to rotate.
[0180] like Figure 13 and Figure 14 As shown, the supporting structure here is a sleeve, with the load-bearing cable or contact wire threaded inside. The sleeve is fixed to the support device. The load-bearing cable moves to the right, compressing the force transmission mechanism. The other end of the force transmission mechanism presses against the sleeve, pushing it to move, thereby driving the support device to rotate. Of course, the other end of the force transmission mechanism (spring) can also act on the left side of the sleeve, pulling the rotating device to rotate (not shown in the figure).
[0181] One end of the elastic mechanism is directly or indirectly connected to the contact wire, and the other end of the elastic mechanism acts on the support device or the supporting structure. Movement of the contact wire compresses or stretches the elastic mechanism, and the pushing or pulling force generated by the elastic mechanism acts on the support device or the supporting structure, thereby pushing or pulling the support device to rotate. It should be noted that the connection method with the contact wire is not shown in the diagram; the connection scheme with the catenary can be referred to.
[0182] As a preferred embodiment, it also includes a clamping mechanism 12 disposed on the catenary and / or contact line;
[0183] The clamping mechanism is installed on the catenary cable in the following manner:
[0184] The first type: the clamping mechanism 12 is disposed on the load-bearing cable inside the supporting structure 7 (as shown in Figure 17); and / or
[0185] The second type: the clamping mechanism 12 is located on the load-bearing cable 1 on one side or on the load-bearing cables on both sides of the supporting structure (e.g., Figure 15 or Figure 16 );
[0186] The clamping mechanism is configured on the contact line as follows:
[0187] The clamping mechanism holds the contact wire, the supporting structure is slidably disposed relative to the supporting device, and the clamping mechanism slides on the supporting device through the supporting structure.
[0188] The clamping mechanism is located on the load-bearing cable on one side or both sides of the sliding contact position between the load-bearing cable and the support device; and / or, the clamping mechanism is located on the contact line on one side or both sides of the contact line between the contact line and the sliding contact position of the support device. Here, the sliding contact position refers to the position where the load-bearing cable and the supporting structure make sliding contact. In this embodiment, the clamping mechanism mainly serves a limiting function. A clamping mechanism on either side of the sliding contact position is called a half-clamping mechanism, and a clamping mechanism on both sides is called a full-clamping mechanism. If a clamping mechanism is provided on both sides, it is the previous embodiment, referred to as the no-clamping case.
[0189] It should be added that during operation, when the outermost support device swings into position and stops rotating (a limiting structure can be used to stop the rotation of the support device; the limiting structure is not a point protected by this patent, and any existing method can be used to stop it from rotating), the other support devices farther away from the stopped support device have not fully swung to one side of the rail. At this time, the catenary and / or contact wire are further pulled, and the clamping mechanism abuts against the supporting structure, using the support structure to push the support device to rotate further. Of course, this is also the core key technology of this patent. In the past, because the catenary and contact wire were fixed to the support device, when the outermost support device rotated into position, the catenary and / or contact wire could not be pulled further, which is why the other support devices in the contact network could not rotate into position.
[0190] To ensure that those skilled in the art can clearly understand, and to meet the requirement of full disclosure in the patent, the question arises why "the remaining support devices may not rotate into position." If it were a rigid contact network, a rotating motor would be installed on each or several columns to drive the cantilever arm. A rigid contact network (with rigid contact lines) can transmit force sequentially, eliminating the possibility of incomplete rotation. In daily life, the contact networks seen on high-speed trains and subways are fixed flexible contact networks. The movable flexible contact network provided in this patent is mainly used in large freight yards, railway container loading and unloading, and warehouse maintenance.
[0191] The flexible contact wire used between the columns is susceptible to problems due to construction errors and the thermal expansion and contraction of the contact wire and catenary, especially over long distances, and even in contact networks used for heavy-haul trains. The longer the distance, the more pronounced the issue becomes where other support devices in the contact network fail to rotate properly. This patent addresses this problem and proposes a solution.
[0192] Therefore, in this field, under such circumstances, traditionally, because the catenary and contact wire are fixed to the support device, when the outermost support device rotates into place, the catenary and / or contact wire cannot be pulled further, which is why the other support devices in the contact network cannot rotate into place.
[0193] This problem has existed since the advent of flexible mobile contact wires. Currently, no publicly available technology or prior patent has addressed this issue, or more specifically, no solution has been found. Therefore, the catenary can move relative to the supporting device; or the contact wire can move relative to the supporting device. This innovative approach breaks through traditional thinking and overturns the current fixed configuration. It is not a solution easily conceived by those skilled in the art. If it were easily conceived, prior art would have already disclosed it. In this field, it is generally accepted that the catenary should be fixed to the supporting device. In existing publicly available technology, once the outermost supporting device has rotated into position, no technology discloses how to further move the catenary or contact wire. Using this method to address the inability of other supporting devices to rotate into position is technically insufficient, neglecting other possibilities and thus hindering research and development in this field. The technology provided by this patent overcomes this technical bias.
[0194] like Figures 18 to 20 As shown, this embodiment, based on the aforementioned clamping mechanism, further incorporates a force transmission mechanism. This force transmission mechanism directly or indirectly transfers the tensile or pushing force generated during the movement of the clamping mechanism on the support cable to the supporting device or supporting structure, thereby pulling or pushing the supporting device to rotate; and / or
[0195] The force transmission mechanism is used to directly or indirectly apply the tensile or pushing force generated during the movement of the clamping mechanism on the contact line to the support device or the supporting structure, thereby pulling or pushing the support device to rotate.
[0196] In a preferred embodiment, one end of the force transmission mechanism acts on the load-bearing cable or is disposed on the clamping mechanism, and the other end of the force transmission mechanism acts on the support device or the supporting structure, and / or,
[0197] One end of the force transmission mechanism acts on the contact line or is set on the clamping mechanism, and the other end of the force transmission mechanism is used on the support device or the supporting structure.
[0198] Preferably, the force transmission mechanism includes a spring, a support cable, or a clamping mechanism that moves to compress or stretch the spring. The pushing or pulling force generated by the spring acts directly or indirectly on the support device or the supporting mechanism, thereby pushing or pulling the support device to rotate; and / or
[0199] The contact line or clamping mechanism moves to compress or stretch the spring, and the pushing or pulling force generated by the spring acts directly or indirectly on the support device or supporting structure, thereby pushing or pulling the support device to rotate.
[0200] like Figure 18 As shown, the other end of the force transmission mechanism 9 acts on the clamping mechanism. The moving force transmission mechanism compresses the force transmission mechanism, and the driving force generated by the transmission mechanism acts directly or indirectly on the supporting mechanism 7, thereby driving the dynamic support device 3 to rotate.
[0201] like Figure 19 As shown, the other end of the force transmission mechanism 9 is used on the support device 3. The moving force transmission mechanism 9 compresses the force transmission mechanism, and the driving force generated by the force transmission mechanism 9 acts directly or indirectly on the support device 3, thereby driving the moving support device to rotate.
[0202] like Figure 20 As shown, the supporting structure 7 here is a sleeve, the load-bearing cable 1 is inserted inside the sleeve, the sleeve is fixed on the support device, the load-bearing cable or clamping mechanism moves the compression force transmission mechanism, and the other end of the force transmission mechanism 9 presses against the sleeve and pushes the sleeve to move, thereby driving the support device to rotate.
[0203] like Figure 21 and Figure 22 As shown, another embodiment of this patent is: the support device is provided with a sliding mechanism, and the load-bearing cable and / or the contact wire slide on the support device through the sliding mechanism.
[0204] Preferably, the sliding mechanism is provided with a slider 11, which is capable of sliding on the supporting structure 7.
[0205] Preferably, it also includes a force transmission mechanism 9, which is used to directly or indirectly apply the thrust or tension generated during the movement of the load-bearing cable, contact line, or sliding mechanism to the support device or the supporting structure 7, thereby pushing or pulling the support device to rotate.
[0206] Furthermore, the force transmission mechanism includes a spring, a support cable and / or a contact wire, a moving compression spring, or a sliding mechanism; the pushing force generated by the spring acts directly or indirectly on the support device or the supporting structure, thereby driving the support device to rotate; or,
[0207] The tension spring is moved by the catenary and / or contact wire, or by the sliding mechanism; the tension force generated by the spring acts directly or indirectly on the support device or the supporting structure, thereby pulling the support device to rotate.
[0208] like Figure 23 As shown, it should be noted that a counterweight device 6 can be added to any of the above embodiments. The counterweight device 6 is connected to the support device 3 by a pull rope. The counterweight device is used to assist the support device in rotating to the non-working position or to the working position.
[0209] like Figure 24 As shown, this patent also provides an operation method for flexible mobile contact networks in large freight yards and containers. The operation method is as follows:
[0210] The catenary wire and / or contact wire are installed on several support devices of the contact network;
[0211] The catenary and / or contact wire are pulled and moved, causing several support devices to rotate from the working position to the non-working position or from the non-working position to the working position; or the rotation of several support devices causes the catenary and / or contact wire to rotate from the working position to the non-working position or from the non-working position to the working position.
[0212] like Figure 24 As shown, in at least one support device, the maximum horizontal movement distance of the catenary and / or contact wire can be greater than the horizontal rotation distance of the corresponding support device.
[0213] Preferably, when at least one support device in the contact network stops rotating, the catenary and / or contact wire is pulled to move further on several support devices; the horizontal distance the catenary and / or contact wire moves in the horizontal direction is greater than or equal to the horizontal distance the support device rotates.
[0214] Preferably, the force transmission mechanism is used to convert the force of further pulling the catenary and / or contact wire into a thrust or pull force that acts on the support device, thereby pushing or pulling several support devices to rotate further to achieve stroke compensation.
[0215] like Figure 25 As shown, the operation method for flexible mobile overhead contact lines in large freight yards and container yards is as follows:
[0216] The catenary wire and / or contact wire are installed on several support devices of the contact network;
[0217] The catenary and / or contact wire slides in the horizontal direction;
[0218] The force transmission structure applies the tensile or pushing force generated during the sliding process of the catenary and / or contact wire to the support device or the supporting structure, thereby pulling or pushing the support device to rotate.
[0219] In at least one support device, the maximum horizontal movement distance of the catenary and / or contact wire can be greater than or equal to the horizontal rotation distance of the support device;
[0220] The load-bearing cable and / or contact wire are pulled, thereby causing several support devices to rotate from the working position to the second position or from the second position to the working position.
[0221] like Figure 26 As shown, the operation method for flexible mobile overhead contact lines in large freight yards and container yards is as follows:
[0222] The catenary and / or contact wire are installed along the length of several support devices on the catenary.
[0223] The catenary and / or contact wire slides in the horizontal direction;
[0224] The force transmission mechanism applies the tensile or pushing force generated during the movement of the clamping mechanism on the catenary and / or contact line to the support device or supporting structure, thereby pulling or pushing the support device to rotate.
[0225] In at least one support device, the maximum horizontal movement distance of the catenary and / or contact wire is greater than or equal to the horizontal rotation distance of the support device;
[0226] The catenary and / or contact wire is pulled, thereby causing several support devices to rotate from the working position to the second position or from the second position to the working position; or the rotation of several support devices causes the catenary and / or contact wire to rotate from the working position to the non-working position or from the non-working position to the working position.
[0227] like Figure 27As shown, the operation method for flexible mobile overhead contact lines in large freight yards and container yards is as follows:
[0228] The catenary and / or contact wire are installed along the length of several support devices on the catenary.
[0229] Pull the catenary and / or contact wire to slide horizontally;
[0230] The force transmission mechanism applies the thrust or tension generated during the movement of the load-bearing cable, contact line, or sliding mechanism to the support device or supporting structure, thereby pushing or pulling the support device to rotate.
[0231] In at least one support device, the maximum distance that the catenary and / or contact wire can be moved by being pulled is greater than or equal to the horizontal distance of rotation of the support device;
[0232] The catenary and / or contact wire is pulled, thereby causing several support devices to rotate from the working position to the second position or from the second position to the working position; or the rotation of several support devices causes the catenary and / or contact wire to rotate from the working position to the non-working position or from the non-working position to the working position.
[0233] Preferably, after the outermost support device of the mobile contact network is in place, it stops rotating, and the catenary and / or the contact wire is further pulled, so that the entire catenary and / or contact wire moves on several support devices.
[0234] Preferably, the catenary or contact wire is further pulled, thereby transmitting the tension of the catenary or contact wire to the support device, the supporting structure, or the sliding mechanism through the force transmission mechanism, thereby driving the support device to rotate further in the direction in which the catenary or contact wire is pulled to achieve stroke compensation.
[0235] like Figure 28 Preferably, the counterweight device 6 is connected to at least one support device via a pull rope;
[0236] The counterweight device itself assists in pulling at least one support device to rotate to a non-working position.
[0237] When at least one support device rotates toward the working position, the counterweight device is lifted by the rotation of the support device; or
[0238] An external lifting mechanism is used (a motor can be installed on the column or support device to lift the counterweight device). After the counterweight device 6 is lifted by the lifting mechanism, several support devices rotate toward the working position.
[0239] It should be further noted that the present invention also includes a rotating mechanism. Figures 9 to 28The image provided is a top view, therefore the rotating mechanism is not shown. For example... Figure 29 As shown, in this embodiment, the rotating mechanism 14 is mounted on the support device 3, and the supporting structure 7 is mounted on the rotating mechanism 14. The rotating mechanism 14 is provided with a supporting shaft, and the supporting structure 7 is mounted in the supporting shaft. The thrust or tension formed by the load-bearing cable or contact wire is directly or indirectly transmitted to the supporting structure 7. When the supporting structure 7 moves to the left or right, the support device rotates along with the force. Through the rotating mechanism 14, there is a relative rotational relationship between the supporting structure 7 and the support device 3, which facilitates operation.
[0240] like Figure 30 In this embodiment, the protective mechanism is mounted on the rotating mechanism. The protective mechanism 8 is mounted on the rotating mechanism 14. Through the rotating mechanism 14, there is a relative rotational relationship between the protective mechanism 8 and the supporting device 3, which facilitates operation.
[0241] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
