Description

Technical Field

[0001] The invention belongs to the field of electrified railway mobile contact network, and in particular relates to a gravity compensation type mobile contact network and an operation control method. Background Art

[0002] With the advancement of railway electrification, China's railway trunk lines are using electric locomotives instead of diesel locomotives. Electrification is achieved in cargo loading and unloading lines or warehousing and maintenance. At present, a rigid movable contact network is used, but the existing rigid movable contact network system is extremely expensive, complex in structure and inconvenient to install, has high requirements for line use conditions, and has poor structural reliability; it uses an electric motor to drive the rotating bracket to rotate, thereby driving the entire movable contact network moving section to the side of the rail. In this way, the bus is installed as a whole at the end of the rotating bracket, and it is difficult to control the synchronization of the motor or electric push rod drive due to the large number of motors.

[0003] On the other hand, the prior art also uses a flexible movable contact network, and uses a motor to directly drag the load-bearing cable on one side of the flexible contact network to move the contact line to the side of the rail. This method has defects such as insufficient dragging force and unstable operation for a long-distance movable contact network of an entire anchor section. Since it only uses one weight, the length of the movable contact network generally does not exceed 800m.

[0004] A 10,000-ton heavy-load train is an extra-long and extra-heavy freight train that is pulled by two or more locomotives. Its characteristics are: large vehicle load capacity; large number of trains. According to the existing railway main technical policies, the effective length of the station's arrival and departure line is 1050m for a 5,000-ton heavy-load freight train, and the effective length of the arrival and departure line of some stations for a 10,000-ton heavy-load freight train on a coal-transporting line is 1700m. It includes unit heavy-load trains, combined heavy-load trains, and complete heavy-load trains.

[0005] For such long-distance heavy-load trains, such as 1,400m to 1,700m 10,000-ton heavy-load trains, if diesel locomotives are used for shunting operations, multiple cars need to be detrained, and the existing technology is costly, requiring the rental of diesel cars to park at the loading and unloading point; when the electric traction vehicle arrives at the loading and unloading point, the diesel car and the electric traction vehicle need to be swapped, which is extremely inefficient; in order to be able to swap traction vehicles, new parking lines and conversion lines need to be built, increasing investment. The key point is that the current diesel locomotives do not have high-power locomotives and cannot tow heavy-load trains. Among the existing flexible contact network technologies, including existing practical applications and prior patent application documents, there is no flexible mobile contact network that can meet the requirements of 10,000-ton train cargo loading and unloading lines or warehousing and maintenance. Summary of the invention

[0006] Through the continuous research and practice of the applicant, a flexible gravity-compensated mobile contact network and operation control method are proposed. Compared with the rigid contact network, the flexible contact network has lower cost, more reliable operation, less weather impact, and simpler maintenance. The contact network provided by this application overcomes the shortcomings of the original dragging method for movement, and uses gravity supplementation for movement. It is effectively improved on the basis of the existing contact network, and can achieve longer distance (1600m-1700m) of overall movement. In addition to being able to meet the existing locomotive freight train cargo loading and unloading lines or storage maintenance, it can also be effectively applied to heavy-load trains such as 10,000-ton trains.

[0028] Preferably, the specific implementation method of at least one rotating swing arm in the mobile contact network providing a swinging driving force to adjust the working state of the entire mobile contact network is: using a power supply device to drive at least one rotating swing arm to rotate; the power supply device is used to drive at least one rotating swing arm to rotate and drive the entire load-bearing cable and / or contact line to swing, so as to achieve, in an unbalanced state, driving the contact line in the mobile contact network to move from a first working position to a second working position; or from the second working position to the first working position.

[0029] As a preferred embodiment, at least one set of motor pulling devices is used to drive at least one rotating swing arm to rotate; the motor pulling device is arranged between any two rotating swing arms in the mobile contact network;

[0030] The motor pulling device rotates forward, pulling an adjacent rotating swing arm to rotate above the rail, driving the entire contact network to be in the first working state; the motor pulling device rotates reversely, pulling another adjacent rotating swing arm to rotate to one side of the rail, driving the entire contact network to be in the second working state;

[0037] The present invention adopts the above technical solution, and the present invention has at least the following beneficial effects:

[0038] 1) In the present invention, the first and second gravity contact network compensation devices are arranged on both sides of the mobile contact network. The first and second gravity contact network compensation devices make the load-bearing cables and / or contact wires in the mobile contact network in a tensioned state, and at least one rotating swing arm provides a swing driving force through a power supply device to adjust the working state of the entire mobile contact network. The gravity compensation mobile contact network provided by the present invention is used in a flexible contact network, and the structure is stable and reliable, and the operation is convenient.

[0039] 2) The traditional rigid movable contact network has a complex structure, needs to carry a rigid bus, has many parts and components, is heavy, and the spacing between the columns is 9-12M. The gravity-compensated movable contact network provided by the present invention can be set at a spacing of 40-50M between the columns. The flexible contact network load-bearing cables provided by the present invention are more evenly stressed, have a short construction period, are less affected by factors such as weather and temperature differences, can be widely used in various harsh environments, have a long service life, can be improved on the basis of the existing contact network, are convenient to install and maintain, and have many advantages such as a similar structure to a fixed contact network.

[0040] 3) In the traditional flexible movable contact network, the load-bearing cable is directly dragged on one side. This method has insufficient dragging force for long-distance mobile contact networks. At the same time, the one-sided dragging method is highly destructive to the structure of the contact network itself, and there are potential safety risks and unstable operation. The present invention adopts a double-sided gravity balance method, which only requires a small external driving force to destroy the original balance system. For this reason, the present invention proposes to use gravity compensation to achieve the movement of the flexible contact network, and adopts a method of setting weights on both sides. By destroying the balance relationship between the two weights, a long-distance, such as (1600m-1700m) overall movement is achieved with less driving force. This movement method is an innovation in the current movable flexible contact network. No existing technology or prior patent has been found to use the device provided by the present invention to achieve the movement of the flexible movable contact network.

[0041] 3) By adopting the device provided by the present invention, 10,000-ton heavy-load trains will no longer use diesel locomotives for shunting operations, which overcomes the traditional situation of needing to decouple multiple cars or even being unable to tow heavy-load trains. It can effectively meet the needs of 10,000-ton train cargo loading and unloading lines or warehousing and maintenance, improve work efficiency, greatly save the cost of purchasing diesel locomotives, and save the existing labor costs for deploying, maintaining and overhauling diesel locomotives.

DETAILED DESCRIPTION

[0053] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices consistent with some aspects of the present invention as detailed in the appended claims.

[0054] like Figure 1 For details, see Figure 1 A, 1B and 1C, this embodiment provides a gravity-compensated mobile contact network, including a mobile contact network 1, a first gravity contact network compensation device 2 and a second gravity contact network compensation device 3; wherein the first and second gravity contact network compensation devices are respectively arranged at the two ends of the mobile contact network 1; the first and second gravity contact network compensation devices make the load-bearing cables 6 and / or the contact wires 7 in the mobile contact network 1 in a tensioned state, and at least one rotating swing arm 5 in the mobile contact network 1 provides a swing driving force to adjust the working state of the entire mobile contact network 1. The mobile contact network 1 includes a plurality of columns 4, each of which is provided with a rotating swing arm 5 that can rotate around the column 4. In this embodiment, it is shown that the load-bearing cables 6 and the contact wires 7 are arranged on the rotating swing arm 5; according to actual use, only a single contact wire 7 can also be arranged on the rotating swing arm 5.

[0055] In this embodiment, the first gravity contact network compensation device 2 includes a first weight 8, and the second gravity contact network compensation device 3 includes a second weight 9; it also includes a first weight frame 10 and a second weight frame 11, the first weight 8 is arranged on the first weight frame 10, and the second weight 9 is arranged on the second weight frame 11. The first weight 8 is arranged at one end of the catenary wire 6 and / or the contact wire 7 in the mobile contact network 1; the second weight 9 is arranged at the other end of the catenary wire 6 and / or the contact wire 7 in the mobile contact network 1. The first weight 8 and the second weight 9 keep the catenary wire 6 and / or the contact wire 7 in the mobile contact network 1 in a tensioned state from both sides through the weight of the weights themselves.

[0056] In this embodiment, when the first and second gravity contact network compensation devices are in a balanced state through the load-bearing cables 6 and / or the contact wire 7, the contact wire 7 in the mobile contact network 1 is in a first working position state or a second working position state; when the first and second gravity contact network compensation devices are in an unbalanced state through the load-bearing cables 6 and / or the contact wire 7, the contact wire 7 in the mobile contact network 1 is driven to move from the first working position state to the second working position state; or, the contact wire 7 in the mobile contact network 1 moves from the second working position state to the first working position state. The first working position state is that the mobile contact network 1 is located above the rail, and the second working position state is that the mobile contact network 1 is located on one side of the rail.

[0057] In the present invention, the weights on both sides are symmetrically arranged, preferably with equal weights, so that the load-bearing cable 6 can be understood to be in a balanced state and will not move left and right in the balanced state. Figure 1 In B and 1C, the left movement of the catenary cable 6 is defined as driving the contact wire 7 to move to the side of the rail (open state, this state is when the train stops for loading and unloading or maintenance), and the right movement of the catenary cable 6 is defined as driving the contact wire 7 to swing back to the top of the rail (the train pantograph is raised to draw power from the contact wire 7, this state is when the train enters or leaves the station). Of course, this left and right definition is not a limitation on the protection of the rights of the present invention. Similarly, according to actual conditions, the right movement of the catenary cable 6 can be defined as the contact wire 7 moving to the side of the rail. The principle is the same and will not be repeated here.

[0058] It should be noted that, in the present embodiment, the gravity contact network compensation device is connected to the load-bearing cable 6 and / or the contact wire 7 at the same time, which is only used as an optimal implementation method. If it is only connected to the load-bearing cable 6, the movement of the load-bearing cable 6 can drive the hanging contact wire 7 to move together. In some cases, if there is only the contact wire 7, the gravity contact network compensation device is only connected to the contact wire 7 to achieve movement, and the contact wire 7 close to the weight can be connected to the pull wire of the weight using an insulator. The principle of this implementation method is the same, so it will not be repeated here.

[0059] The present invention discusses a flexible contact network, not an existing rigid contact network. The mobile contact network 1 includes a plurality of columns 4, each of which is provided with a rotating swing arm 5 that can rotate around the column 4, and the load-bearing cable 6 and the contact wire 7 are arranged on the rotating swing arm 5; or the contact wire 7 is arranged on the rotating swing arm 5. The present invention provides a gravity-compensated mobile contact network used in a flexible contact network. Gravity compensation on both sides is the key, and the load-bearing cable 6 and / or the contact wire 7 need to be in a tensioned state at all times.

[0060] The core idea of ​​the present invention is to drive at least one rotating swing arm 5 to rotate by external force. Since the weights on both sides always keep the load-bearing cable 6 and / or the contact line 7 in a tensioned state, as long as at least one rotating swing arm 5 rotates, the rotating swing arms 5 in the mobile contact network will be driven to rotate, thereby realizing that the contact line 7 is in the first working position state or the second working position state.

[0061] The overall idea is: this embodiment also includes a power supply device for driving at least one rotating swing arm 5 to rotate, and the power supply device is used to drive at least one rotating swing arm 5 to rotate and drive the entire load-bearing cable 6 and / or the contact wire 7 to swing, so as to achieve, in an unbalanced state, driving the contact wire 7 in the mobile contact network 1 to move from a first working position to a second working position; or from a second working position to the first working position.

[0062] The present invention provides four implementation schemes for driving the rotating swing arm 5 to rotate:

[0063] The first implementation method:

[0064] like Figure 2 and Figure 2A As shown, the power supply device includes at least one group of motor pulling devices 12, and the motor pulling device 12 is arranged between any two rotating swing arms 5 in the mobile contact network 1; the motor pulling device 12 rotates forward to pull an adjacent rotating swing arm 5 to rotate above the rail, driving the entire contact network to be in a first working state; the motor pulling device 12 rotates reversely to pull another adjacent rotating swing arm 5 to rotate to one side of the rail, driving the entire contact network to be in a second working state.

[0065] According to the length of the flexible mobile contact network 1, multiple groups of motor pulling devices 12 can be set in the entire section of the mobile contact network 1, and another column 4 can be set between any two rotating swing arms 5. A pulling motor 121 is installed on the column 4. Two turntables are set at the output end of the pulling motor. The pull rope of one turntable 122 is connected to a rotating swing arm 5, and the pull rope of the other turntable 123 is connected to another rotating swing arm 5. When the pulling motor rotates forward, one turntable reels in and pulls the rotating swing arm 5 connected to it to move, and the other turntable releases the wire. The pulling motor reverses the working principle in the same way and will not be repeated.

[0066] In this way, assuming that the motor is pulled to rotate forward, the corresponding rotating swing arm 5 swings above the rail, the rotating swing arm 5 swings, the first weight 8 rises, and the second weight 9 falls. Since the load-bearing cable 6 in the entire flexible contact network is always in a tensioned state, the balance state is broken, so the contact line 7 is driven to move from the second position state to the first position state. That is, it swings from one side of the rail to the top of the rail. As shown in the figure, it swings from state 1C to state 1B.

[0067] Similarly, pull the motor to reverse, and the corresponding rotating swing arm 5 swings to one side of the rail. The rotating swing arm 5 swings, the second weight 9 rises, and the first weight 8 falls. Since the load-bearing cable 6 in the entire flexible contact network is always in a tensioned state, the balance state is broken, so the contact line 7 is driven to move from the first position state to the second position state. That is, it swings from the top of the rail to the side of the rail. As shown in the figure, it swings from state 1B to state 1C.

[0068] The second implementation method:

[0069] like Figure 3As shown, the power supply device includes at least one first motor 13 and at least one second motor 14. At least one first motor 13 correspondingly pulls at least one rotating swing arm 5 to swing above the rail to drive the entire contact network to be in the first working state; at least one second motor 14 correspondingly pulls at least one rotating swing arm 5 to swing to one side of the rail to drive the entire contact network to be in the second working state.

[0070] According to the length of the flexible mobile contact network 1 (the length of the contact line 7 of the present invention can reach 1600 meters to 1700 meters, and the existing device uses a weight, and a weight generally manages a length of 800 meters), a column 4 can be set between any two rotating swing arms 5, and a first motor 13 can be installed on at least one column 4, and a second motor 14 can be installed on at least one other column 4.

[0071] Assume that when one or more first motors 13 rotate forward, the pull rope is contracted, and the corresponding rotating swing arm 5 is pulled to swing to one side of the rail. At the same time, one or more second motors 14 release the wire, and the rotating swing arm 5 pulled by the first motor 13 swings, the first weight 8 rises, and the second weight 9 falls. Since the load-bearing cable 6 in the entire flexible contact network is always in a tensioned state, the balance state is broken, so the contact line 7 is driven to move from the second position state to the first position state. That is, it swings from one side of the rail to the upper rail. As shown in the figure, it swings from state 1C to state 1B.

[0072] Similarly, when one or more second motors 14 rotate forward, the pull rope is contracted, and the corresponding rotating swing arm 5 is pulled to swing to one side of the rail. At the same time, one or more first motors 13 release the wire, and the rotating swing arm 5 pulled by the second motor 14 swings, the second weight 9 rises, and the first weight 8 falls. Since the load-bearing cable 6 in the entire flexible contact network is always in a tensioned state, the balance state is broken, so the contact line 7 is driven to move from the first position state to the second position state. That is, it swings from the top of the rail to the side of the rail. As shown in the figure, it swings from state 1B to state 1C.

[0073] The third implementation method:

[0074] like Figure 4 As shown, the electric push rod 15 in this embodiment is bidirectional, and the specific scheme is: the power supply device includes at least one electric push rod 15, and more than one electric push rod 15 is adapted to push more than one rotating swing arm 5 to swing. The output shaft of more than one electric push rod 15 extends to push the corresponding rotating swing arm 5 to swing above the rail, driving the entire contact network to be in the first working state; the output shaft of more than one electric push rod 15 retracts to pull the corresponding rotating swing arm 5 to swing to one side of the rail, driving the entire contact network to be in the second working state.

[0075] The electric push rod 15 is installed on the column 4. The output shaft of more than one electric push rod 15 extends to push the corresponding rotating swing arm 5 to swing above the rail, the first weight 8 rises, and the second weight 9 falls. Since the load-bearing cable 6 in the entire flexible contact network is always in a tensioned state, the balance state is broken, so the contact line 7 is driven to move from the second position state to the first position state. That is, it swings from the top of the rail to one side of the rail. As shown in the figure, it swings from state 1C to state 1B.

[0076] Similarly, the output shaft of more than one electric push rod 15 retracts and pulls the corresponding rotating swing arm 5 to swing to one side of the rail, the second weight 9 rises, and the first weight 8 falls. Since the load-bearing cable 6 in the entire flexible contact network is always in a tensioned state, the balance state is broken, so the contact line 7 is driven to move from the first position state to the second position state. That is, it swings from the top of the rail to the side of the rail. As shown in the figure, it swings from state 1B to state 1C.

[0077] In this embodiment, the above-mentioned implementation assumes that the electric push rod 15 is installed in the main viewing Figure 1 A is installed on the left side of the column 4; if it is installed on the right side of the column 4, the output shaft of the electric push rod 15 extends to push the corresponding rotating swing arm 5 to swing to one side of the rail. The installation method is not limited to the present invention, and the above description is only for explaining the claims, and does not limit the scope of protection of the present invention.

[0078] As a preferred implementation, in this embodiment, a hydraulic push rod that works in both directions can also be used.

[0079] Specifically, the power supply device includes at least one hydraulic push rod, and more than one hydraulic push rod is adapted to push more than one rotating swing arm to swing.

[0080] The output shaft of more than one hydraulic push rod extends out to push the corresponding rotating swing arm to swing above the rail, driving the entire contact network to be in the first working state; the output shaft of more than one hydraulic push rod retracts to pull the corresponding rotating swing arm to swing to one side of the rail, driving the entire contact network to be in the second working state.

[0081] The hydraulic push rod provided in this embodiment is consistent with the installation method, action principle, and usage scenario of the electric push rod in the third embodiment. Figure 4 The description of the first and third embodiments will not be repeated here.

[0082] The fourth implementation method:

[0083] like Figure 5As shown, the power supply device includes at least one rotating motor 16, and the rotating swing arm 5 is arranged on the column 4 through a rotating shaft; more than one rotating motor 16 drives more than one rotating shaft to rotate, thereby causing the corresponding rotating swing arm 5 to swing and rotate; more than one rotating motor 16 drives the rotating swing arm 5 to swing above the rail and drives the entire contact network to be in the first working state when it rotates forward; more than one rotating motor 16 drives the rotating swing arm 5 to swing to one side of the rail and drives the entire contact network to be in the second working state when it rotates reversely.

[0084] Assuming that one or more of the rotating motors 16 rotate forward to drive the rotating swing arm 5 to swing above the rail, the first weight 8 rises, and the second weight 9 falls. Since the load-bearing cable 6 in the entire flexible contact network is always in a tensioned state, the balance state is broken, so the contact line 7 is driven to move from the second position state to the first position state. That is, it swings from the top of the rail to one side of the rail. As shown in the figure, it swings from state 1C to state 1B.

[0085] Similarly, one or more of the rotating motors 16 reverse and drive the rotating swing arm 5 to swing to one side of the rail, the second weight 9 rises, and the first weight 8 falls. Since the load-bearing cable 6 in the entire flexible contact network is always in a tensioned state, the balance state is broken, so the contact line 7 is driven to move from the first position state to the second position state. That is, it swings from the top of the rail to the side of the rail. As shown in the figure, it swings from state 1B to state 1C.

[0086] like Figure 6 As shown, another aspect of this embodiment provides a gravity-compensated mobile contact network operation control method, the operation control method adopts the above-mentioned gravity-compensated mobile contact network, and the specific steps are as follows:

[0087] S1. The first and second gravity contact network compensation devices are respectively arranged at the two ends of the mobile contact network; the first and second gravity contact network compensation devices make the load-bearing cables and / or contact wires in the mobile contact network in a tensioned state, and at least one rotating swing arm in the mobile contact network provides a swinging driving force to adjust the working state of the entire mobile contact network.

[0088] S2. When the first and second gravity contact network compensation devices are in a balanced state through the load-bearing cables and / or the contact wires, the contact wires in the mobile contact network are in a first working position state or a second working position state; when the first and second gravity contact network compensation devices are in an unbalanced state through the load-bearing cables and / or the contact wires, the contact wires in the mobile contact network are driven to move from the first working position state to the second working position state; or, the contact wires in the mobile contact network move from the second working position state to the first working position state. The first working position state is that the mobile contact network is located above the rails, and the second working position state is that the mobile contact network is located on one side of the rails.

[0089] As a preferred embodiment, the specific implementation method of at least one rotating swing arm in the mobile contact network in this embodiment providing a swinging driving force to adjust the working state of the entire mobile contact network is: using a power providing device to drive at least one rotating swing arm to rotate; the power providing device is used to drive at least one rotating swing arm to rotate and drive the entire load-bearing cable and / or contact line to swing, so as to achieve, in an unbalanced state, driving the contact line in the mobile contact network to move from a first working position to a second working position; or from the second working position to the first working position.

[0090] The schematic diagram of this operation method can be referred to the schematic diagram in the device. The following operation methods are provided.

[0091] See also Figure 2 and Figure 2A , using at least one set of motor pulling devices to drive at least one rotating swing arm to rotate; the motor pulling device is arranged between any two rotating swing arms in the mobile contact network;

[0092] The motor pulling device rotates forward, pulling an adjacent rotating swing arm to rotate above the rail, driving the entire contact network to be in the first working state; the motor pulling device rotates reversely, pulling another adjacent rotating swing arm to rotate to one side of the rail, driving the entire contact network to be in the second working state;

[0093] The specific operation method is: pull the motor to rotate forward, and the corresponding rotating swing arm 5 swings above the rail. The rotating swing arm 5 swings, the first weight 8 rises, and the second weight 9 falls. Since the load-bearing cable 6 in the entire flexible contact network is always in a tensioned state, the balance state is broken, so the contact line 7 is driven to move from the second position state to the first position state. That is, it swings from one side of the rail to the top of the rail. As shown in the figure, it swings from state 1C to state 1B.

[0094] Similarly, pull the motor to reverse, and the corresponding rotating swing arm 5 swings to one side of the rail. The rotating swing arm 5 swings, the second weight 9 rises, and the first weight 8 falls. Since the load-bearing cable 6 in the entire flexible contact network is always in a tensioned state, the balance state is broken, so the contact line 7 is driven to move from the first position state to the second position state. That is, it swings from the top of the rail to the side of the rail. As shown in the figure, it swings from state 1B to state 1C.

[0095] See also Figure 3 , use at least one first motor and at least one second motor to drive the rotating swing arm to rotate; at least one first motor correspondingly pulls at least one rotating swing arm to swing above the rail to drive the entire contact network to be in a first working state; at least one second motor correspondingly pulls at least one rotating swing arm to swing to one side of the rail to drive the entire contact network to be in a second working state.

[0096] The specific operation method is: when one or more first motors 13 rotate forward, the pull rope is retracted, and the corresponding rotating swing arm 5 is pulled to swing to one side of the rail. At the same time, one or more second motors 14 release the wire, and the rotating swing arm 5 pulled by the first motor 13 swings, the first weight 8 rises, and the second weight 9 falls. Since the load-bearing cable 6 in the entire flexible contact network is always in a tensioned state, the balance state is broken, so the contact line 7 is driven to move from the second position state to the first position state. That is, it swings from one side of the rail to the upper rail. As shown in the figure, it swings from state 1C to state 1B.

[0097] Similarly, when one or more second motors 14 rotate forward, the pull rope is contracted, and the corresponding rotating swing arm 5 is pulled to swing to one side of the rail. At the same time, one or more first motors 13 release the wire, and the rotating swing arm 5 pulled by the second motor 14 swings, the second weight 9 rises, and the first weight 8 falls. Since the load-bearing cable 6 in the entire flexible contact network is always in a tensioned state, the balance state is broken, so the contact line 7 is driven to move from the first position state to the second position state. That is, it swings from the top of the rail to the side of the rail. As shown in the figure, it swings from state 1B to state 1C.

[0098] See also Figure 4 , at least one electric push rod is used to drive at least one rotating swing arm to rotate; more than one electric push rod is adapted to push more than one rotating swing arm to swing; the output shaft of more than one electric push rod is extended to push the corresponding rotating swing arm to swing above the rail, driving the entire contact network to be in a first working state; the output shaft of more than one electric push rod is retracted to pull the corresponding rotating swing arm to swing to one side of the rail, driving the entire contact network to be in a second working state;

[0099] The specific operation method is: the output shaft of more than one electric push rod 15 extends to push the corresponding rotating swing arm 5 to swing above the rail, the first weight 8 rises, and the second weight 9 falls. Since the load-bearing cable 6 in the entire flexible contact network is always in a tensioned state, the balance state is broken, so the contact line 7 is driven to move from the second position state to the first position state. That is, it swings from the top of the rail to one side of the rail. As shown in the figure, it swings from state 1C to state 1B.

[0100] Similarly, the output shaft of more than one electric push rod 15 retracts and pulls the corresponding rotating swing arm 5 to swing to one side of the rail, the second weight 9 rises, and the first weight 8 falls. Since the load-bearing cable 6 in the entire flexible contact network is always in a tensioned state, the balance state is broken, so the contact line 7 is driven to move from the first position state to the second position state. That is, it swings from the top of the rail to the side of the rail. As shown in the figure, it swings from state 1B to state 1C.

[0101] The structural diagram of the installation of the hydraulic push rod is not shown in this embodiment. The installation method, operation principle, and usage scenario of the hydraulic push rod and the electric push rod are the same, and can be referred to Figure 4 shown.

[0102] At least one hydraulic push rod is used to drive at least one rotating swing arm to rotate; more than one hydraulic push rod is adapted to push more than one rotating swing arm to rotate; the output shaft of more than one hydraulic push rod is extended to push the corresponding rotating swing arm to swing above the rail, driving the entire contact network to be in a first working state; the output shaft of more than one hydraulic push rod is retracted to pull the corresponding rotating swing arm to swing to one side of the rail, driving the entire contact network to be in a second working state.

[0103] See also Figure 5 , using at least one rotating motor to drive at least one rotating swing arm to rotate; the rotating swing arm is arranged on the column through a rotating shaft; more than one rotating motor drives more than one rotating shaft to rotate, thereby causing the corresponding rotating swing arm to swing;

[0104] One or more of the rotating motors rotate forward to drive the rotating swing arm to swing above the rail, driving the entire contact network to be in a first working state; one or more of the rotating motors rotate backward to drive the rotating swing arm to swing to one side of the rail, driving the entire contact network to be in a second working state.

[0105] The specific operation method is: one or more of the rotating motors 16 rotate forward to drive the rotating swing arm 5 to swing above the rail, the first weight 8 rises, and the second weight 9 falls. Since the load-bearing cable 6 in the entire flexible contact network is always in a tensioned state, the balance state is broken, so the contact line 7 is driven to move from the second position state to the first position state. That is, it swings from the top of the rail to one side of the rail. As shown in the figure, it swings from state 1C to state 1B.

[0106] Similarly, one or more of the rotating motors 16 reverse and drive the rotating swing arm 5 to swing to one side of the rail, the second weight 9 rises, and the first weight 8 falls. Since the load-bearing cable 6 in the entire flexible contact network is always in a tensioned state, the balance state is broken, so the contact line 7 is driven to move from the first position state to the second position state. That is, it swings from the top of the rail to the side of the rail. As shown in the figure, it swings from state 1B to state 1C.
