Description

Technical Field

[0001] This invention belongs to the field of mobile overhead contact system for electrified railways, specifically relating to mobile overhead contact system compensation mechanisms and mobile overhead contact systems. 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, the goal of continuous innovation by those skilled in the art is to provide electrified contact networks that can continuously meet the needs of cargo loading and unloading lines or warehouse maintenance. Summary of the Invention

[0004] Existing technologies also use flexible, movable contact wires, employing motors to directly drag the catenary cable from one side of the flexible contact wire, shifting the contact wire to the side of the rail; however, this approach has the following drawbacks:

[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. Construction errors exist in the spacing between the columns, verticality, and tension of the catenary and contact wire between the cantilever arms. According to existing major railway technical policies, for 5000t heavy-haul freight trains, the effective length of the arrival and departure tracks at stations is 1050m. For 10000t heavy-haul freight trains on coal transport lines, the effective length of the 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 network may not swing properly when it swings above or to the side of the railway.

[0007] 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.

[0008] Through the applicant's continuous research and practice, the above solution can effectively move the catenary and / or contact wire to one side or above the rail. However, a new problem arises in actual use: When the cantilever arm is set to rotate 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), the other cantilever arms do not fully swing to one side of the rail. The further the rotating cantilever arm is from the rightmost cantilever arm, the smaller its offset. This means that when the rightmost cantilever arm stops swinging, the other cantilever arms have not yet rotated to their positions. This is especially problematic for long-distance heavy-haul trains with mobile overhead contact lines of about 1600 meters. When the rightmost cantilever arm stops swinging after it reaches its position, the other cantilever arms, which are far from the rightmost cantilever arm, are still not fully swinging, or even positioned above or to the side of the rail. This can affect the loading and unloading of large freight yards, containers, and other goods. In addition, due to the incomplete swinging, there may be poor contact or inability to make contact with the pantograph to obtain power, which can affect the entry or exit of freight trains.

[0009] 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.

[0010] 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.

[0011] 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.

[0060] The present invention has the following beneficial effects:

[0061] 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.

[0062] 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 position, 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 swing further. This can solve the problem of all support devices in the existing mobile contact network not being able to be positioned correctly.

[0063] 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.

[0064] 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.

[0115] 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.

[0116] The first aspect of this invention provides a mobile contact wire compensation mechanism. Traditionally, the catenary and contact wire are fixed to a rotating bracket, and the rotation of the bracket moves the catenary and contact wire from one side of the rail to above the rail or vice versa. Through continuous research and innovation, the applicant has proposed a revolutionary design where the catenary and contact wire are not fixed to the rotating bracket. This allows the catenary and contact wire to move freely without being affected by construction errors or thermal expansion and contraction. 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 approach is to slide the catenary and / or contact wire on the rotating arm via 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.

[0117] like Figures 1 to 4 As shown, this embodiment provides a mobile overhead contact line compensation mechanism, including a support device 3, and further including a catenary cable 1 and / or a contact wire 2.

[0118] 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, and then move the catenary and contact wire by rotating the arm. Here, the rotating arm can be understood as a type of support device. The support device 3 is rotatably mounted on the column 4. The support device 3 has many different forms and structures, such as... Figures 1 to 3 As shown, where, Figure 1 This is the case where only the catenary cable 1 is present; Figure 2 In cases involving both a catenary and a contact wire, the catenary is positioned in the upper half of the support structure, while the contact wire is positioned in the lower half of the support structure. Figure 3 A rotatable rotating shaft 13 is set at the end of the crossbar, a load-bearing cable 1 is set at the upper end of the rotating shaft 13, and a contact wire 2 is set at the lower end of the rotating shaft 13. Figure 4 In cases involving both a catenary cable and a contact wire, the upper part of the support device is raised diagonally upwards to install the catenary cable, and the upper part is lowered diagonally downwards to install the contact wire. Figures 1 to 4 This document merely states that the types of support devices are diverse. Regardless of the form of the support device, as long as the load-bearing cable can move relative to the support device, and / or the contact wire can move relative to the support device, it falls within the scope of protection of this patent. The forms of support devices are not limited to this, and will not be exhaustively described here.

[0119] In this invention, the catenary 1 is movable relative to the support device 3; or the contact wire 2 is movable relative to the support device 3. Regarding the issue of electrical isolation, an insulator 5 can be installed on the support device to solve the problem.

[0120] In a preferred embodiment, the catenary 1 and / or the contact wire 2 slide directly on the support device 3, or the catenary 1 and / or the contact wire 2 slide indirectly on the support device 3.

[0121] In a preferred embodiment, when the catenary 1 and / or the contact wire 2 slide directly on the support device, the support device is provided with a support structure 7, and the catenary 1 and / or the contact wire 2 can slide in the support structure 7.

[0122] One method for setting the catenary and / or contact wire is as follows:

[0123] The catenary cable is capable of sliding within the supporting structure; and / or

[0124] The contact line is capable of sliding within the supporting structure;

[0125] or

[0126] The second method for setting up the catenary and / or contact wire is as follows:

[0127] The catenary cable is capable of sliding within the supporting structure; and / or

[0128] The contact line causes the supporting structure to slide on the support device.

[0129] 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.

[0130] 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.

[0131] like Figure 9 As shown, in a preferred embodiment, the catenary cable and / or contact wire of the supporting structure slide directly within the supporting structure. Long-term reciprocating sliding causes wear. Therefore, a protective structure 8 is provided in the area where the catenary cable or contact wire slides reciprocally. The catenary cable 1 passes through the protective structure 8, and the protective structure 8 can slide within the supporting structure 7. In this embodiment, the protective structure 8 is a sleeve, and the catenary cable passes through the sleeve, which can slide within the supporting structure.

[0132] As an alternative, Figure 9 The protective structure 8 can be replaced with pre-twisted wire, which is wrapped around the load-bearing cable. The load-bearing cable wrapped with pre-twisted wire can slide in the support structure 7, which is not shown in the figure; of course, the pre-twisted wire can be wrapped first, and then a sleeve can be added.

[0133] like Figure 10As shown, during the left and right movement (sliding) of the catenary, it can squeeze and rub the support device (support structure), thereby driving the support device to rotate. In this embodiment, the support device can be rotated by the catenary and / or contact wire alone, or a rotating motor can be installed on the column to drive the support device to rotate and thus drive the catenary to move.

[0134] The present invention can also use a force transmission mechanism to solve the rotation problem, and at the same time use a force transmission mechanism to solve the problem of the contact wire side orientation (non-working position) not being in place.

[0135] This embodiment also includes a force transmission mechanism, which is used to apply the thrust or tension generated during the movement of the catenary cable to the support device, thereby pulling or pushing the support device to rotate; or, the force transmission mechanism is used to apply the thrust or tension generated during the movement of the contact wire to the support device, thereby pulling or pushing the support device to rotate.

[0136] like Figure 11 and Figure 12 As shown, in this embodiment, one end of the force transmission mechanism 9 acts indirectly or directly on the load-bearing cable 1, and the thrust or tension generated by the force transmission mechanism 9 acts indirectly or directly on the support device 3 (e.g., Figure 12 (as shown) or on the supporting structure 7 (such as Figure 11 (as shown), or,

[0137] like Figure 13 As shown, one end of the force transmission mechanism is disposed on the contact line, and the thrust or pull force generated by the force transmission mechanism acts on the support device (e.g., Figure 13 (as shown) or on the supporting structure (not shown in the figure for this method).

[0138] In this embodiment, the force transmission mechanism can be a retractable elastic mechanism. One end of the elastic mechanism is mounted on the load-bearing cable, and the other end is mounted on the support device. The load-bearing cable moves to compress or stretch the spring mechanism, and the pushing or pulling force generated by the elastic mechanism acts on the support device, thereby pushing or pulling the support device to rotate; or

[0139] One end of the elastic mechanism is disposed on the contact line, and the other end of the elastic mechanism is disposed on the support device. The contact line moves to compress or stretch the elastic mechanism, and the pushing or pulling force generated by the elastic mechanism acts on the support device, thereby pushing or pulling the support device to rotate.

[0140] like Figure 14As shown, in a preferred embodiment, the elastic mechanism is preferably a spring. During implementation, one end of the spring 9 is set on the load-bearing cable 1, and the other end of the spring is set on the support device 3. The load-bearing cable 1 moves to compress the spring 9, and the pushing force formed by the spring acts on the support device, thereby driving the support device to rotate.

[0141] like Figure 15 As shown, in a preferred embodiment, the elastic mechanism is preferably a spring. During implementation, one end of the spring 9 is set on the load-bearing cable 1, and the other end of the spring is set on the support device 3. The load-bearing cable 1 moves to stretch the spring, and the tension force generated by the spring acts on the support device, thereby pulling the support device to rotate.

[0142] like Figure 16 As shown, in a preferred embodiment, the elastic mechanism is preferably a spring. During implementation, one end of the spring 9 is set on the load-bearing cable 1, and the other end of the spring is set on the support structure 3. The load-bearing cable 1 moves to compress the spring 9, and the pushing force formed by the spring acts on the support structure, thereby driving the support device to rotate.

[0143] like Figure 17 As shown, the force transmission mechanism 9 is disposed inside the supporting structure 7, which is a sleeve. The thrust generated by the force transmission mechanism 9 acts on the supporting structure. A schematic diagram of its rotation is shown below. Figure 18 As shown, the catenary cable is pulled, causing the spring to compress. The resulting thrust acts on the sleeve, which is fixedly mounted on the support device. Therefore, during the pulling process of the catenary cable, the spring force drives the support device to rotate.

[0144] In the embodiments provided by this invention, one end of the spring is disposed on the load-bearing cable, and the other end of the spring is disposed on the support device. Movement of the load-bearing cable compresses or stretches the spring, and the pushing or pulling force generated by the spring acts on the support device, thereby pushing or pulling the support device to rotate; or

[0145] One end of the spring is disposed on the contact line, and the other end of the spring is disposed on the support device. The movement of the contact line compresses or stretches the spring, and the pushing or pulling force generated by the spring acts on the support device, thereby pushing or pulling the support device to rotate.

[0146] The following is a further optimized embodiment based on the above implementation scheme;

[0147] like Figure 19As shown, this embodiment also includes a clamping mechanism 12, which is disposed on the catenary and / or contact line. The clamping mechanism clamping the catenary and / or contact line can move together with the catenary and / or contact line.

[0148] The clamping mechanism is installed on the catenary cable in the following manner:

[0149] The first type: the clamping mechanism is disposed on the load-bearing cable inside the supporting structure (sleeve); such as Figure 20 As shown.

[0150] and / or

[0151] The second type: the clamping mechanism is located on the load-bearing cable on one side or on both sides of the supporting structure, such as... Figure 19 As shown.

[0152] The clamping mechanism is configured on the contact line as follows:

[0153] 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 via the supporting structure. (See here for more information.) Figure 8 The implementation method.

[0154] The sliding contact position here refers to the position where the catenary cable and the supporting structure make sliding contact. In this implementation scheme, the clamping mechanism mainly serves to limit movement. Setting it on either side of the sliding contact position is called half clamping, and setting it on both sides is called full clamping. If it is set on both sides, it is the previous implementation scheme, which is called the case of no clamping.

[0155] It should be added that the benefits of a single moving mechanism with a clamping structure are not easily apparent. However, when placed within a complete moving contact network, which includes several support devices, the benefits are not immediately apparent. The catenary cable and / or contact wire are extended along the support devices. During operation, when the outermost support device swings into position and stops rotating (a limiting structure can be used to stop the rotation; this limiting structure is not protected by this patent, and any existing method can be used to prevent rotation), the remaining support devices, which are farther from the stopped support device, have not fully swung to the side of the rail. At this point, the catenary cable and / or contact wire are further pulled, and the clamping structure abuts against the supporting structure, using the pressure of the supporting structure to push the support devices to rotate further. This is, of course, the core technical concept of this patent. Traditionally, because the catenary cable and contact wire are fixed to the support devices, when the outermost support device rotates into position, the catenary cable and / or contact wire cannot be pulled further, resulting in the remaining support devices in the contact network not rotating into position.

[0156] 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.

[0157] 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.

[0158] 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.

[0159] 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.

[0160] like Figure 21The above-described implementation scheme further includes a counterweight device 14, which is connected to the support device indirectly or directly via a pull rope; the counterweight device is used to assist the support device in rotating to a non-working position. The working position refers to the contact wire rotating above the railway, and the non-working position refers to the contact wire rotating to the side of the railway. The solution provided in this patent mainly studies the situation where the contact wire swings to the side of the railway and needs to reach the desired position.

[0161] In the above-mentioned embodiments containing a clamping mechanism, the clamping mechanism mainly serves to limit the movement. The load-bearing cable and / or contact wire slide in the supporting structure. A counterweight device can also be used to assist the support device in rotating to a non-working position, or a rotating motor can be used on the column to drive the support device to rotate.

[0162] As another preferred embodiment, in the above embodiment containing a clamping mechanism, a force transmission structure 9 is introduced to drive the support device to rotate. The specific implementation is as follows:

[0163] like Figures 22 to 25 As shown, this embodiment also includes a force transmission mechanism 9, which is used to indirectly or directly apply the thrust or tension generated during the movement of the clamping mechanism 12 on the load-bearing cable to the support device 3, thereby pulling or pushing the support device 3 to rotate.

[0164] or,

[0165] The force transmission mechanism is used to indirectly or directly apply the thrust or pull force generated during the movement of the clamping mechanism on the contact line to the support device, thereby pulling or pushing the support device to rotate.

[0166] The force transmission mechanism is located between the clamping mechanism and the supporting device at the sliding contact position. The force transmission mechanism can be arranged on any side of the contact position or on both sides of the contact position.

[0167] This embodiment further explains the implementation of the force transmission mechanism: one end of the force transmission mechanism is disposed on the load-bearing cable or on the clamping mechanism, and the other end of the force transmission mechanism is disposed on the support device (e.g., Figure 23 and 24 (as shown) or on the supporting structure (such as Figure 22 and Figure 25 ,in Figure 22 The force transmission mechanism 9 is located outside the supporting mechanism 7 (slip ring). Figure 25 The force transmission mechanism 9 is located inside the support mechanism (sleeve), or one end of the force transmission mechanism is located on the contact line (e.g., Figure 13 ) or set on the clamping mechanism (such as Figure 26 (The spring acts indirectly), and the other end of the force transmission mechanism 9 is disposed on the support device 3 (e.g., the spring acts indirectly). Figure 13 ) or on the supporting structure 7 (such as Figure 26 ).

[0168] One end of the force transmission mechanism is mounted on the load-bearing cable, and the other end of the force transmission mechanism acts indirectly or directly on the support device; or, one end of the force transmission mechanism acts indirectly or directly on the contact line, and the other end of the force transmission mechanism is mounted on the support device.

[0169] Here, one end of the force transmission mechanism is set on the load-bearing cable or contact line on any side of the supporting structure, and the other end is set at any position of the support device. Since the support device is also equipped with a supporting structure, this patent limits the support device to include a supporting structure. Therefore, the other end is set on the support device and includes the supporting structure set in the support device.

[0170] The force transmission mechanism includes a retractable elastic mechanism, a load-bearing cable or clamping mechanism that moves to compress or stretch the elastic mechanism, and the pushing or pulling force generated by the elastic mechanism acts indirectly or directly on the support device, thereby pushing or pulling the support device to rotate; or

[0171] The contact line or clamping mechanism moves to compress or stretch the elastic mechanism, and the pushing or pulling force generated by the elastic mechanism acts indirectly or directly on the support device, thereby pushing or pulling the support device to rotate.

[0172] In one preferred embodiment, the elastic mechanism employs a spring, a support cable, or a clamping mechanism to move, compress, or stretch the spring. The pushing or pulling force generated by the spring acts indirectly or directly on the support device, thereby pushing or pulling the support device to rotate; or

[0173] The contact line or clamping mechanism moves to compress or stretch the spring, and the pushing or pulling force generated by the spring acts indirectly or directly on the support device, thereby pushing or pulling the support device to rotate.

[0174] Regarding the arrangement of the elastic mechanism (spring), one end of the elastic mechanism acts on the clamping mechanism, and the other end acts on the supporting structure. The spring can be sleeved on the load-bearing cable or contact wire, or it can be not sleeved on the load-bearing cable or contact wire, for example, it can be arranged parallel to the load-bearing cable or contact wire, as long as it can transmit force. Alternatively, one end of the elastic mechanism can be set on the load-bearing cable or clamping mechanism, and the other end can act directly on the supporting device.

[0175] like Figures 27 to 29 As shown, in another implementation, when the catenary and / or the contact wire slides indirectly on the support device, the support device is provided with a sliding mechanism 10, and the catenary and / or the contact wire slides on the support device 3 through the sliding mechanism 10.

[0176] In a preferred embodiment, the sliding mechanism is provided with a sliding member 11, and the support device 3 is provided with a supporting structure 7, and the sliding member 11 can slide on the supporting structure 7.

[0177] like Figures 30 to 32 As shown, in a preferred embodiment, it also includes a force transmission mechanism 9, which is used to indirectly or directly apply 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 the supporting structure, thereby pushing or pulling the support device to rotate.

[0178] In a preferred embodiment, one end of the force transmission mechanism acts indirectly or directly on the load-bearing cable, contact line, or sliding mechanism, while the other end of the force transmission mechanism acts indirectly or directly on the support device or supporting structure.

[0179] like Figure 31 and Figure 32 In a preferred embodiment, the force transmission mechanism 9 is provided on the sliding member 11 on any side of the supporting structure, or the force transmission mechanism is provided on the sliding members on both sides of the supporting structure (not shown in the figure in this embodiment).

[0180] In one preferred embodiment, the force transmission mechanism includes a spring, a moving compression spring of a load-bearing cable and / or contact wire, or a moving compression spring of a sliding mechanism; the pushing force generated by the spring acts on the support device or the supporting structure, thereby driving the support device to rotate; or, a moving tension spring of a load-bearing cable and / or contact wire, or a moving tension spring of a sliding mechanism; the pulling force generated by the spring acts on the support device or the supporting structure, thereby pulling the support device to rotate.

[0181] like Figure 33 As shown, in a preferred embodiment, it also includes a counterweight device 14, which is connected to the support device 3 indirectly or directly via a pull rope; the counterweight device 3 is used to assist the support device in rotating to a non-working position.

[0182] This embodiment also provides a flexible contact network, which includes several support devices, and the support devices adopt the compensation mechanism described above.

[0183] like Figure 34 The diagram shows a structural schematic of a force transmission mechanism 9, with one end fixed to the load-bearing cable 1 and the other end acting on the support device 3.

[0184] like Figure 35 This is a schematic diagram of the contact wire structure with clamping structure 12.

[0185] like Figure 36This is a schematic diagram of the contact wire structure with force transmission structure 9 installed inside the sleeve.

[0186] This embodiment also provides a flexible overhead contact line, which includes several support devices, and the support devices employ the compensation mechanism described above. Figure 37 The diagram shows a structural schematic.

[0187] This embodiment also provides a flexible contact network, which includes several support devices, and the support devices adopt the compensation mechanism described above.

[0188] like Figure 38 As shown in the figure, a counterweight device 14 is installed on a support device. According to the claims, all the aforementioned contact wires in this embodiment can be equipped with a counterweight device 14. Depending on the actual application, at least one support device may be equipped with a counterweight device 14.

[0189] This invention directly changes the traditional solution, allowing the load-bearing cable to move relative to the support device; or the contact wire to move relative to the support device, thus eliminating construction errors and the effects of thermal expansion and contraction.

[0190] 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 position, 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 swing further. This solves the problem of all support devices in existing mobile contact networks not being able to be positioned correctly.

[0191] 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 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. Figure 39 As 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 40 As can be seen, at this time, the external drag mechanism 13 ( Figure 40The dragging mechanism 13 (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.

[0192] like Figure 41 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 is always greater than L2 at any position during the rotation.

[0193] 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.

[0194] 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.

[0195] The most significant innovation of this overhead contact system is that the maximum horizontal movement distance of the catenary and / or contact wire is greater than or equal to the horizontal rotation distance (rotation radius) of the supporting device. In other words, the catenary and / or contact wire are not fixed to the supporting device. Traditionally, the catenary and contact wire are fixed to the cantilever arms. Any rotation of the cantilever arm or pulling of the catenary results in a horizontal movement distance of less than or equal to the rotation radius of the cantilever arm. This is especially problematic in long-distance mobile overhead contact systems, where construction errors and thermal expansion and contraction can cause issues. For example, in summer, when cantilever arm a has rotated to its position and stopped, cantilever arms c and d, which are farther away, cannot rotate to their correct positions.

[0196] 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.

[0197] 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.

[0198] Additionally, it should be noted that this utility model also includes a rotating mechanism. The embodiments and accompanying drawings provided above are top views, therefore the rotating mechanism is not shown. Figure 42 As shown, in this embodiment, the rotating mechanism 15 is mounted on the support device 3, and the supporting structure 7 is mounted on the rotating mechanism 15. The rotating mechanism 15 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 15, there is a relative rotational relationship between the supporting structure 7 and the support device 3, which facilitates operation.

[0199] like Figure 43 In this embodiment, the protective mechanism 8 is mounted on the rotating mechanism 15. Through the rotating mechanism 15, the protective mechanism 8 and the supporting device 3 have a relative rotational relationship, facilitating operation.

[0200] 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.
