Description

Technical Field

[0001] The invention belongs to the field of mobile catenary of electrified railways, and particularly relates to a hydraulic transmission mechanism, a lateral displacement wrist arm positioning device, a mobile catenary and an operation method. Background Art

[0002] In traditional railway loading and unloading, diesel locomotives are used to tow freight cars in and out of the loading and unloading operation areas. This method requires replacing the traction head, resulting in difficult railway locomotive scheduling and low efficiency, wasting resources. In the case of heavy-haul trains, multiple shunting diesel locomotives are often required to meet the traction demand. In some coal mining departments, there is also a method of using the inertia of electric locomotives to slide through the loading and unloading operation areas, and a non-powered area is set in the loading and unloading operation areas to ensure the safety of loading and unloading operations. The method of using the inertia of electric locomotives to slide through the coal loading and unloading operation areas makes it difficult to control the stopping point of the locomotive. Once the parking position is not properly controlled and the electric locomotive stops in the non-powered area, it will cost a high rescue fee to move the train to the powered area.

[0003] With the advancement of railway electrification traction, electric locomotives have replaced diesel locomotives in the transportation of China's main railway lines. In the electrification of cargo loading and unloading lines or in-storage maintenance, rigid movable catenaries are used. The existing rigid movable catenary system has a complex structure, inconvenient installation, high requirements for line usage conditions, and poor structural reliability. If the movable section of the mobile catenary is on one side of the entire railway track, one way is to use an electric motor to drag the carrier cable to move the contact wire to one side of the railway track. For a long-distance mobile catenary, this method has insufficient towing force and unstable operation. Another way is to use an electric motor or an electric push rod to drive the rotating bracket to rotate, thereby driving the entire movable section of the mobile catenary to move to one side of the railway track. In this method, the busbar is installed as a whole at the end of the rotating bracket, and it is difficult to control the synchronization of the driving of the electric motor or the electric push rod.

[0004] Currently, in one way, a heavy anchor arm is connected with a steel wire rope, and the steel wire rope passes through a pulley block and uses the cooperation of an electric actuator to realize the recovery of the catenary. In another way, an electric motor is used to drive the rotating bracket to realize lateral displacement.

[0005] With the innovation of electrified railway technology, technicians in this field continue to innovate and upgrade technology to provide an electrified mobile catenary that can meet the requirements of cargo loading and unloading lines or in-storage maintenance. Summary of the Invention

[0006] In the prior art, there are also flexible movable catenaries. An electric motor is used to directly drag the carrier cable on one side of the flexible catenary to move the contact wire to one side of the railway track. There are also catenaries with pantographs lifted by mechanical drive. Even when lifted, the catenary cannot be completely moved outside the railway, which still affects the loading and unloading of large goods. If a rotating pantograph is used to swing the catenary left and right to one side of the railway, there is still the defect that it cannot be completely swung to one side of the railway. The following are its deficiencies:

[0007] 1. Thermal expansion and contraction will definitely cause the extension of the contact wire and the carrier cable, which may lead to pantograph-catenary faults (faults between the train pantograph and the catenary), such as serious safety accidents like the compensation device for adjusting the wire tension falling to the ground, the pantograph offset, and the positioner detaching. If the contact wire is slack and wraps around the train pantograph (a horizontal plate lifted high above the locomotive head), it will then pull down the catenary pole, derail the locomotive, and tip over the carriages, with extremely serious consequences.

[0008] 2. The carrier cable and the contact wire are fixedly installed on the rotating pantograph. There are construction errors in the spacing, perpendicularity between the columns, and the tension of the carrier cable and the contact wire between the pantographs.

[0009] According to the existing main railway technical policies, for heavy-haul freight trains with a capacity of 5000t, the effective length of the arrival and departure tracks at the station is 1050m. For heavy-haul freight trains with a capacity of 10000t running on dedicated coal transportation 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 ten-thousand-ton heavy-haul trains, due to the influence of thermal expansion and contraction and the existence of construction errors, when the movable catenary rotates above or to the side of the railway, there is a situation where the rotation is not in place.

[0010] The existing method is to set a counterweight at one end of the movable catenary and a dragging mechanism at the other end of the movable catenary. By pulling the carrier cable and / or the contact wire through the dragging mechanism, the contact wire is moved from one side of the railway track to above the railway track or from above the railway track to one side of the railway track.

[0011] Through continuous research and practice by the applicant, the above solution can effectively drive the carrier cable and / or the contact wire to move to one side of the railway track or above the railway track. However, a new problem will arise during actual use: when the cantilever is set to rotate to the right to drive the contact wire and the carrier cable to move to one side of the railway track, due to the characteristics of thermal expansion and contraction of the contact wire and the carrier cable, when the rightmost cantilever moves to one side of the railway track (the cantilever is approaching parallel to the railway track, which can be understood as completely swinging to one side, leaving the space above the railway), the other cantilevers do not completely rotate to one side of the railway track (it can be understood that there is at least one cantilever in the entire catenary that does not completely swing to one side of the railway. For a long-distance catenary, there is a situation where it stops swinging above the side of the railway because the rightmost cantilever has swung in place). The farther the rotating cantilever is from the right cantilever, the smaller its offset. That is, when the rightmost cantilever stops rotating, the other cantilevers have not rotated in place yet. Especially for the mobile catenary applicable to heavy-haul trains with a length of about 1600 meters, when the rightmost cantilever reaches the position and stops rotating, the other cantilevers farther from the right end cantilever are still in a state of not rotating in place, and even above the side of the railway track. This will affect the loading and unloading operations of other goods such as large freight yards and containers. In addition, due to the incomplete rotation, there will be a situation where the pantograph has poor power collection contact or cannot contact and obtain power, affecting the entry or exit of freight trains.

[0012] The applicant places the existing defects in the part of the invention content, aiming to illustrate that the raising of this technical problem is also a part of the present invention. There is no solution to this technical problem in the current publicly available technologies.

[0013] In the existing flexible catenary technologies, including the existing actual application technologies and the prior patent application documents, neither the defect nor the relevant solution has been disclosed. The applicant is confident that it is the first to provide a solution to this technical defect in this industry. If this defect cannot be solved, it will directly affect the operation of the mobile catenary, resulting in potential safety hazards during the commercial use of the mobile catenary. Therefore, the applicant has provided a complete set of solutions through research and applied for intellectual property protection for this.

[0014] To achieve the above object, the applicant provides a set of technical solutions that can effectively solve the defect of the incomplete movement of the carrier cable and the contact wire in the existing mobile catenary. Moreover, it has a lower cost, more reliable operation, less affected by weather, and simpler maintenance compared with the rigid catenary. The catenary provided in this application also overcomes the deficiency of the original method of moving by dragging and instead uses the method of gravity supplement for movement. It is effectively improved on the basis of the existing catenary, and can achieve the overall movement over a longer distance (1600m - 1700m). In addition to being able to meet the loading and unloading lines or in-storage maintenance of freight trains of existing locomotives, it can also be effectively applied to heavy-haul trains such as ten-thousand-ton trains.

[0015] To achieve the above object, the traditional method is to fixedly secure the carrier cable and the contact wire to the rotating cantilever arm, and drive the carrier cable and the catenary to move from one side of the railway track to above the railway track or from above the railway track to one side of the railway track by rotating the rotating cantilever arm. Through continuous research and innovation, the applicant proposes a revolutionary setting method, that is, the carrier cable and the contact wire are not fixedly secured to the rotating cantilever arm, so that the carrier cable and the contact wire can be free from the influence of construction errors and thermal expansion and contraction during the rotation process.

[0016] The applicant provides two technical ideas in two directions. The first is to let the carrier cable directly move reciprocally on the cantilever arm structure, and this method also directly eliminates the traditional "carrier cable clamping seat and contact wire contact seat". The second is to transfer the tension or thrust formed during the movement of the carrier cable to the cantilever arm structure through a force transmission member, so as to push or pull the cantilever arm structure to rotate; of course, another method can also be adopted, that is, the cantilever arm structure is driven to rotate, and the force formed during the rotation of the cantilever arm structure is transferred to the carrier cable through a force transmission member, so as to drive or pull the carrier cable to move. The core idea is that the carrier cable is not fixedly secured to the cantilever arm structure. Only when it is not fixedly secured can it overcome the influence brought by construction errors and the problem that the carrier cable cannot rotate in place due to thermal expansion and contraction. Only when it is not fixedly secured can it further achieve compensation. This is the biggest innovation point of this patent and the biggest difference from the prior art, which brings beneficial effects and solves the technical problems that the prior art cannot solve.

[0017] As for the driving method of the cantilever arm structure, the dragging mechanisms at both ends of the carrier cable and the contact wire, etc. are not the points studied in this patent. The patent assumes that the carrier cable and the contact wire can be pulled to move left or right, or the cantilever arm mechanism can be driven to rotate, including using a rotating motor to drive the cantilever arm structure to rotate, or using an electric push rod or a hydraulic push rod to push the cantilever arm structure to rotate, that is, the carrier cable and the contact wire can be pulled to move from one side of the railway track to above the railway track or from above the railway track to one side of the railway track.

[0018] To achieve the above object, in a first aspect of the present invention, a force transmission mechanism is provided.

[0029] The wrist arm structure drives the kit to rotate, and the kit directly or indirectly compresses or stretches the elastic force transmission member to form a thrust or a pull, and the kit transmits the thrust or the pull to the moving member, thereby pushing or pulling the moving member to move.

[0030] Furthermore, the pushing member has an extended surface extending outwards;

[0031] When the force transmission member includes a pushing member, the extended surface can directly / indirectly press against and contact the kit during the movement; or

[0032] When the force transmission member includes a pushing member and an elastic force transmission member, the extended surface can press against and contact the elastic force transmission member during the movement.

[0033] Furthermore, a support rotating shaft is arranged in the rotating mechanism, the support rotating shaft can rotate, and the kit is directly or indirectly arranged on the support rotating shaft.

[0034] Furthermore, it further includes an intermediate connecting member, the kit is arranged on the intermediate connecting member, and the intermediate connecting member is arranged on the support rotating shaft.

[0035] Furthermore, the moving member adopts any one of the following methods:

[0055] The present invention adopts the above technical solutions and has at least the following beneficial effects:

[0056] 1). A force transmission mechanism is adopted to act on the cantilever structure with the thrust or pull force formed during the process of the carrier cable, thereby pulling or pushing the cantilever structure to rotate. With this structural change, the cantilever can generally be rotatably installed on the column and can rotate under any driving force. Therefore, the force transmission member is used to push or pull the support device to rotate. In this way, even when the outermost support device rotates in place (in place generally means swinging to one side of the railway), as long as the carrier cable can be further pulled, the force transmission member provided can push or pull the cantilever structure to further rotate to achieve compensation, so as to solve the situation that all cantilevers in the existing mobile catenary cannot swing in place.

[0057] 2). There is a relative movement relationship between the moving member (carrier cable) and the cantilever structure. The moving member is slidably arranged, effectively overcoming the influence brought by construction errors and thermal expansion and contraction.

[0058] 3). The carrier cable of the flexible catenary provided by the present invention is more evenly stressed, has a short construction period, is less affected by factors such as weather and temperature difference, can be widely applied in various harsh environments, has a long service life, can be improved on the basis of the existing catenary, is convenient for installation, maintenance, and has many advantages such as a similar fixed catenary structure.

[0059] 4). With the contact wire provided by the present invention, the ten-thousand-ton heavy-haul train will no longer use diesel locomotives for shunting operations, overcoming the situation of traditional multi-car decoupling and even being unable to tow heavy-haul trains, effectively meeting the needs of the ten-thousand-ton train for cargo loading and unloading lines or warehousing maintenance, improving work efficiency, and greatly saving the cost of purchasing diesel locomotives and the labor costs for the existing deployment, maintenance, and repair of diesel locomotives.

[0073] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. On the contrary, they are merely examples of devices consistent with some aspects of the present invention as detailed in the appended claims.

[0074] As Figure 1As shown in the figure, the schematic diagram of the traditional mobile catenary is set so that the cantilever rotates to the right to drive the carrier cable to move to one side of the railway track (non-working position). Due to the influence of construction errors and thermal expansion and contraction on the carrier cable, when the rightmost cantilever a moves to one side of the railway track (the cantilever is parallel to the railway track, leaving the space above the railway), the other cantilevers (cantilevers a to d) do not completely rotate to one side of the railway track (it can be understood that there is at least one cantilever in the entire catenary that does not completely swing to one side of the railway. For a long-distance catenary, there is a situation where it stops swinging above the side of the railway because the rightmost cantilever has swung in place). The farther the rotating cantilever is from the rightmost cantilever, the smaller its offset. That is, when the rightmost cantilever stops rotating, the other cantilevers have not rotated in place yet. Especially for the mobile catenary of about 1600 meters for heavy-haul trains applicable to long distances, when the rightmost cantilever stops rotating after reaching the position, the other cantilevers farther from the rightmost cantilever are still in a state of not rotating in place, and even above the side of the railway track. This will affect the loading and unloading operations of other goods such as large freight yards and containers. In addition, due to the incomplete rotation, there is a situation where the pantograph has poor power-taking contact or cannot contact and obtain power, which affects the entry or exit of freight trains.

[0075] On the one hand, this embodiment provides a force transmission mechanism. The force transmission mechanism is applied to the cantilever structure in the mobile catenary and includes a moving member 1, a force transmission member, and a rotating mechanism 4. Among them, the rotating mechanism 4 is arranged on the cantilever structure 5. In this embodiment, the force transmission member is used to transmit force to the cantilever structure 4 to push or pull the cantilever structure 4 to rotate; or the force transmission member is used to transmit force to the moving member 1 to push or pull the moving member 1 to move. The cantilever structure 5 in this embodiment can be arranged on the column 6 or at a convenient fixing position such as a gantry.

[0076] The present invention directly changes the traditional inherent scheme, uses the catenary itself as a transmission part, and sets it to be movable (to be fixed on the arm structure). The catenary provided by the present invention can slide back and forth on the arm structure, and there is a relative movement relationship. The maximum horizontal movement distance of the catenary along the horizontal direction can be greater than the horizontal distance of the corresponding arm structure rotation. It needs to be supplemented here that only in the case of sliding can the maximum horizontal movement distance of the catenary along the horizontal direction be greater than the horizontal distance of the corresponding arm structure rotation. If the catenary is fixed on the arm structure, then the horizontal movement distance of the catenary along the horizontal direction is equal to the horizontal distance of the corresponding arm structure rotation. It is precisely because of the relative sliding relationship that the construction error and the influence of thermal expansion and contraction can be eliminated. It is precisely because of the existence of relative sliding that structural innovation is carried out, using force transmission parts to transmit force. When the load-bearing cable is pulled (the initiator of the force is an external weight or a dragging mechanism pulling the load-bearing cable), the force generated during the movement of the load-bearing cable is transmitted to the wrist-arm structure to drive the wrist-arm structure to rotate to the working position or non-working position; when the wrist-arm structure rotates (when the initiator of the force is the wrist-arm structure driven to rotate by a rotating motor or a push rod, etc.), the force of the rotation of the wrist-arm structure is transmitted to the moving part (load-bearing cable) through the force-bearing part using the force transmission part, thereby driving the load-bearing cable to move. This method breaks through the traditional thinking, which believes that the catenary cables need to be fixed on the wrist arm, and the movement of the catenary cables is driven by the rotation of the wrist arm, or the catenary cables are directly pulled to move; the existing related technologies (related papers and existing published patents) are all like this. The present invention breaks through the traditional thinking. During the movement or rotation of the catenary cables, the catenary cables and / or the contact wires are still in a relative movement relationship, that is, the maximum horizontal movement distance of the catenary cables and / or the contact wires along the horizontal direction can be greater than the horizontal rotation distance of the corresponding wrist arm structure. The benefit brought by this is that the problem of construction error is effectively solved, and the problem of thermal expansion and contraction of the load-bearing cable is also effectively solved. Here, it needs to be supplemented that since the transmission load-bearing cable is fixed on the arm, due to the existence of thermal expansion and contraction, the contact network will not be able to be swung into place when it reaches the railway from the side. This problem has been explained above and will not be repeated here. Another biggest highlight of the present invention is that during the side swing of the overall contact network, since the moving part (load-bearing cable) is a sliding setting, it can move back and forth on the arm structure, so it provides a basis for further stroke compensation in place. Elastic force transmission parts (such as springs, or other elastic force transmission parts) can be used. The energy storage effect of the elastic force transmission parts can further push or pull the arm structure to further swing to achieve stroke compensation. In this way, compared with the existing swinging situation, this solution can perfectly solve this problem, especially for long-distance, such as 1700M mobile contact networks, the load-bearing cables and / or contact lines can be perfectly swung to one side of the railway, and the swing is in place.Existing mobile contact lines, such as using rigid catenaries or flexible catenaries, cannot reach a length of 1700M, or use multiple sections of mobile contact lines for splicing, which are relatively complex in components and construction and have high costs. Of course, some people may ask that if a rotating motor is set at the root of each wrist arm, the situation of indirect incomplete swing can also be achieved. In existing prior patents and actual applications, this method is basically not adopted because a single motor failure will affect the operation of the entire mobile contact line, resulting in high failure rates, high costs, and complex system control. Therefore, the present invention aims to provide a structure with low failure rates. In terms of the current technology, the structure of the present invention has the lowest failure rate, stable and reliable operation, and the key is that the operation is simple and the swinging effect is good.

[0077] In this embodiment, the force transmission member is adopted in the following manner:

[0078] As Figure 2 shown, in the first case, the force transmission member includes a pushing member 2, and the pushing member 2 is arranged on the moving member 1;

[0079] As Figure 3 shown, in the second case, the force transmission member includes an elastic force transmission member 3; or

[0080] As Figure 4 shown, in the third case, the force transmission member includes a pushing member 2 and an elastic force transmission member 3.

[0081] This embodiment further includes a kit 7, which is directly or indirectly arranged on the rotating mechanism 4, and the force transmission member is arranged in the kit 7; the moving member 1 moves to push or pull the force transmission member, and the force transmission member forms a thrust or pull to drive the kit 7 to move; or, the wrist arm structure 5 rotates to push or pull the force transmission member, and the force transmission member forms a thrust or pull to drive the moving member 1 to move.

[0082] In this embodiment, the force transmission member has two working forms: Now, the first transmission member method is described: When the moving member 1 (which can be understood as the load-bearing cable 10) is pulled and moves, Figure 2Shown is the case of moving to the right. One end of the force transmission member acts on the moving member 1, and the other end of the force transmission member directly or indirectly acts on the kit 7. The direct action is that the pusher 2 directly acts on the kit 7, and the indirect action is to set a component on any position of the kit 7 that can receive the force of the pusher 2. The same effect can also be achieved through the indirect action of the force-receiving component. The pusher 2 is arranged on the moving member 1. When the moving member 1 moves, it drives the pusher 2 to move to the right. During the movement, it will push the kit 7 to move together. The kit 7 is arranged on the boom structure 5, so it pushes the boom structure 5 to rotate, causing it to swing to the working position (the catenary 10 and / or the contact wire are located above the railway, and the pantograph can draw power) or the non-working position (the catenary 10 and / or the contact wire move to one side of the railway, leaving the space above the railway for operations such as cargo handling and maintenance). In this embodiment, the working principle of the moving member 1 moving to the left is the same and will not be elaborated.

[0083] It should be added that: in this embodiment, the force-receiving part can be any position of the kit 7 itself. Preferably, the force-receiving part is two end faces inside the kit 7 (such as Figure 2 the positions indicated by A and B in the figure); during the reciprocating left and right movement of the force transmission member, the force transmission member (the pushing part or the elastic force transmission member 3) abuts against the left end face or the right end face inside the kit 7, thereby driving the kit 7 to move. The kit 7 transmits the force to the boom structure 5, so that the rotation of the boom structure 5 is driven by the movement of the moving member 1; another implementation form is: when the boom structure 5 is driven to rotate, during the rotation of the kit 7 together, the force-receiving part will abut against the force transmission member (the pushing part or the elastic force transmission member 3), thereby pushing or pulling the moving member 1 (the catenary 10) to move.

[0084] In addition, the force-receiving part can also be other intermediate members integrally and fixedly arranged on the kit 7 for receiving force (such as Figure 6 shown in the figure). For example, the intermediate member can be a stop block. The force transmission member transmits thrust or tension during movement. As long as the intermediate member can abut during the movement of the force transmission member.

[0085] Another working implementation is: when the boom structure 5 is driven to rotate, it drives the kit 7 to rotate. During the rotation of the kit 7, the force is applied to the pusher 2, thereby driving the moving member 1 (the catenary 10) to move. It swings to the working position or the non-working position. In this embodiment, the working principle of the moving member 1 moving to the left is the same and will not be elaborated.

[0086] Taking Figure 4 as an example to illustrate that the force transmission member has two working forms: when the moving member 1 moves to the left, it compresses the elastic force transmission member 3 through the pusher 2 to form a thrust to push the kit 7. The kit 7 transmits the thrust to the boom structure 5, thereby pushing the boom structure 5 to rotate; one end of this spring is not fixed, and the other end of the spring can be fixed on the pusher 2 or not fixed on the pusher 2.

[0087] In another working mode, the right rotation of the boom structure 5 drives the right rotation of the kit 7. The kit 7 acts on the pusher 2 through a spring, and the movement of the pusher 2 drives the movement of the moving part 1 (to move).

[0088] Such as Figure 5 shown, if one end of the spring is directly or indirectly fixed on the kit 7, and the other end of the spring is fixed on the pusher 2, the right movement of the moving part 1 stretches the elastic force transmission member 3 through the pusher 2 to form a tensile force. The kit 7 transmits the tensile force to the boom structure 5, thereby pulling the boom structure 5 to rotate;

[0089] In this embodiment, the pusher 2 has an extended surface extending outward; when the force transmission member includes the pusher 2, the extended surface can directly / indirectly press against the kit 7 during the movement process (not shown in the figure); or

[0090] Such as Figure 6 shown, when the force transmission member includes the pusher 2 and the elastic force transmission member 3, the extended surface 17 can press against the elastic force transmission member 32 and / or press against the kit 7 during the movement process.

[0091] Such as Figure 7 shown, in this embodiment, a support rotating shaft 41 is provided in the rotating mechanism 4. The support rotating shaft can rotate, and the kit 7 is directly or indirectly provided on the support rotating shaft 41. Figure 6 What is shown is that the kit 7 is directly provided on the support rotating shaft 41.

[0092] Such as Figure 8 shown, it further includes an intermediate connecting member 128. The kit 7 is provided on the intermediate connecting member 128, and the intermediate connecting member 128 is provided on the support rotating shaft 41. The intermediate connecting member 128 adopts a cross bar. The kit 7 can be directly provided on the cross bar, or a clamp seat can be adopted. The clamp seat is provided on the cross bar, and the kit 7 is then provided on the clamp seat.

[0093] In addition, it should be supplemented and explained that in this embodiment, the catenary 10 can be used as the moving part 1. This implementation method can be referred to Figures 2 to 5 . Or the method in Figure 8 can also be adopted. The moving part 1 includes a moving part body 9 and catenaries 1010 provided at both ends of the moving part body 9. This is only one implementation method of the moving part 1. Whether the catenary 10 is integral or the catenary 10 is interrupted, as long as it can drive the catenary 10 to move.

[0094] This embodiment further provides a moving catenary side-shifting boom positioning device, including a boom structure 5. Among them, at least one boom structure 5 uses the above force transmission mechanism. It can be referred to Figures 2 to 7Any one of them.

[0095] The contact wire in this embodiment can be arranged in the following ways:

[0096] As Figure 8 shown in the figure, the first way: It further includes a suspension member 11, one end of the suspension is arranged on the catenary 10, and the other end of the suspension is connected to the contact wire; or

[0097] As Figure 9 shown in the figure, the second way: It further includes a clamping structure 13, and the contact wire is arranged on the boom structure 5 through the clamping structure 13;

[0098] Furthermore, when using the first way: It further includes a connecting member 12, one end of the connecting member 12 is connected to the suspension member 11, and the connecting member 12 is directly or indirectly arranged on the boom structure 5; or

[0099] The connecting member 12 is directly or indirectly arranged on the rotating mechanism 4.

[0100] This embodiment also provides a method for operating a mobile catenary, characterized in that: this operating method uses the above-mentioned mobile catenary, and includes the following steps:

[0101] The moving member 1 is forced to move;

[0102] The moving member 1 moves to compress or stretch the force transmission member, and the force transmission member forms a thrust or a pull to drive the kit 7 to move;

[0103] The kit 7 transmits the force to the boom structure 5, thereby pushing or pulling the boom structure 5 to rotate;

[0104] Or

[0105] The boom structure 5 rotates;

[0106] The force transmission member is compressed or stretched to form a thrust or a pull;

[0107] The kit 7 transmits the thrust or the pull to the moving member 1, thereby pushing or pulling the moving member 1 to move.

[0108] As a preferred embodiment, the moving member 1 is further pulled, and the force - transmitting member is further compressed or stretched. The kit 7 transmits the force to the boom structure 5 directly or indirectly through the force - transmitting member, thereby pushing or pulling the boom structure 5 to rotate further to achieve stroke compensation. It should be added that since the moving member 1 is slidably arranged on the boom structure 5, when the boom stops rotating, the moving member 1 can still be further pulled. For example, when the outermost boom in the moving catenary stops rotating (usually rotates to the side of the railway), at this time, some other boom structures 5 have not rotated in place, and the moving member 1 can be further pulled. The elastic force - transmitting members 3 in several positioning devices push or pull the boom structure 5 to rotate further to achieve stroke compensation.

[0109] Or

[0110] The boom structure 5 is further driven to rotate, and the kit 7 transmits the force to the moving member 1 directly or indirectly through the force - transmitting member, thereby pushing or pulling the moving member 1 to move further.

[0111] It should be added that in the prior art, during the operation, when the outermost boom structure swings in place and stops rotating (a limiting structure can be used to block the support device from rotating. The limiting structure is not the point protected by this patent, and any existing method can be used to block it from rotating), the remaining boom structures farther away from the stopped - rotating boom structure have not fully swung to the side of the railway track. At this time, the carrier cable and / or the contact wire are further pulled. Of course, this is also the most core key technical idea of this patent. Traditionally, since the carrier cable and the contact wire are fixed to the boom structure, when the outermost support device rotates in place, the carrier cable and / or the contact wire cannot be further pulled, so there will be a situation where the remaining support devices in the catenary do not rotate in place.

[0112] To enable those skilled in the art to clearly understand and at the same time meet the requirement of full disclosure in the patent, the reason for the "situation where the remaining boom structures do not rotate in place" is as follows. In the case of a rigid catenary, a rotating motor is set on each column or several columns to drive the boom to rotate. For a rigid catenary (the contact wire is rigid), the force can be transmitted one by one, and there will be no situation where the rotation is not in place. When traveling by high - speed train or subway in daily life, what is seen is a fixed flexible catenary. The movable flexible catenary provided by this patent is mainly used in large freight yards, railway container cargo loading and unloading, warehousing and maintenance, etc.

[0113] The flexible contact wire used between the columns, due to construction errors and the influence of thermal expansion and contraction of the contact wire and the carrier cable, especially for long distances, and even for the catenary used by heavy-haul trains with a capacity of 10,000 tons, the longer the distance, the more obvious the situation that the other supporting devices in the catenary cannot rotate in place. This patent discovers problems and proposes solutions from this perspective.

[0114] Therefore, it can be said that in this field and in such a scenario, traditionally, since the carrier cable and the contact wire are fixed to the supporting device, when the outermost supporting device rotates in place, the carrier cable and / or the contact wire cannot be further pulled, so there is a situation where the other supporting devices in the catenary cannot rotate in place.

[0115] Since the day when the flexible mobile catenary appeared, this problem has always existed. In the existing publicly available technologies and existing prior patents, this problem point has not been found or disclosed for the time being, or more specifically, no solution to this problem point has been found. The carrier cable can move relative to the cantilever structure; or the contact wire can move relative to the cantilever structure. This innovative idea itself breaks through the traditional thinking and subverts the current fixed setting method. It is not a technical solution that is easily thought of by those skilled in the art. If it could be easily thought of, there should have been prior art disclosures long ago. In this field, it is considered that it should be fixed to the supporting device. In the existing publicly available technologies, when the outermost supporting device rotates in place, no technology discloses that the carrier cable or the contact wire can be further moved. And the ability to further rotate or move to achieve compensation in this patent is one of the biggest technical highlights of the patent.

[0116] It should be added that in this embodiment, the contact wire and / or the carrier cable in the mobile catenary move from the working position to the non-working position; or from the non-working position to the working position, adopting any one or a combination of two or more of the following methods:

[0117] Such as Figure 10 As shown, the first method: includes a first counterweight structure 14 and a second counterweight structure 15. The first counterweight structure acts on one end of the mobile catenary, and the second counterweight structure is arranged at the other end of the mobile catenary; the first counterweight structure and the second counterweight structure adjust the working state of the mobile catenary from both ends of the mobile catenary;

[0118] Such as Figure 11 As shown, the second method: includes a counterweight structure (the setting method of the first counterweight can be referred to) and a dragging mechanism 16. The counterweight structure acts on one end of the catenary, and the dragging mechanism is arranged at the other end of the catenary. By pulling the counterweight structure to move through the dragging mechanism, the working state of the mobile catenary is adjusted;

[0119] The third method: adding a rotatable anchor arm mechanism (not shown in the figure) in the above first method, the anchor arm mechanism is arranged at any end of the catenary, or both ends are provided; the first counterweight structure and / or the second counterweight structure drives the anchor arm mechanism to rotate, and the rotating anchor arm mechanism drives the carrier cable and / or the contact wire to move the working state of the catenary; or

[0120] The fourth method: a rotatable anchor arm mechanism in the above second method, the anchor arm mechanism is arranged at any end of the catenary, or both ends are provided;

[0121] The counterweight structure directly acts on one end of the catenary, or the counterweight structure drives the anchor arm mechanism to rotate, and the rotating anchor arm mechanism drives the carrier cable and / or the contact wire to move the working state of the catenary;

[0122] The dragging mechanism directly acts on one end of the catenary, or the dragging mechanism drives the anchor arm mechanism to rotate, and the rotating anchor arm mechanism drives the carrier cable and / or the contact wire to move the working state of the catenary; or

[0123] The fifth method: using a rotating motor (not shown in the figure), the rotating motor is used to drive at least one boom structure in the movable catenary to rotate.

[0124] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
