Description

Technical Field

[0001] The present invention belongs to the technical field of mobile contact networks, and in particular relates to a hidden mobile contact network with a column lifting and tilting drive device and an operating method. Background Art

[0002] In recent years, the number of shunting operations for train pickup and delivery has been reduced, and loading and unloading lines have been designed and constructed according to a through-type design to achieve straight-through access. However, in electrified sections, most loading and unloading lines with full-train access are for coal trains loaded in open-top containers. When using a reach stacker for loading and unloading, the fixed reach stacker under the overhead contact line cannot operate. The only option is to connect the entire train to the departure line, and then use the diesel shunting locomotive to transfer the train to the loading and unloading line. This method cannot truly achieve straight-through access, seriously wastes machine power, and requires shunting personnel (at least 6 people at each station), which is inefficient. At present, foreign mobile contact networks adopt a rigid form. Due to the rigid suspension, rigid mobile contact networks are only suitable for use in depots due to weather, temperature differences and other reasons. They are also very expensive, require a lot of maintenance, and have a high failure rate. Domestic mobile contact networks are of two types: rigid and flexible. Flexible mobile contact networks retract and release the load-bearing cables and contact wires. The flexible mobile contact network is similar to the contact network structure on existing lines, and is easy to maintain, has a low cost, a very low failure rate, and is easy to maintain. The disadvantage is that due to construction and thermal expansion and contraction, the load-bearing cables and contact wires are often close to the vehicle body, which has a huge impact on loading and unloading when loading and unloading large goods or gantry crane operations.

[0003] Electrified railway freight loading and unloading yards use a mobile contact network to power freight trains. When the mobile contact network is in the working position—that is, when the contact wire is above the rails—freight trains can enter or exit. Once a train enters the station, the mobile contact network moves the contact wire to the side of the track, freeing up space above the track for loading, unloading, or maintenance. The existing mobile contact network swings to the side of the track, with left and right columns located on the side. The arm that swings to the side of the track is approximately 3 to 4 meters above the center of the track. The columns of the mobile contact network are relatively close to the track, necessitating consideration of the safe distance between the hoisting equipment and the arm during lifting operations. Freight trains are prone to contact with the load-bearing cables and contact wires, posing a safety hazard. Because the columns and arm are located high, the vertical columns block the side of the track during lifting operations, hindering gantry crane loading and unloading operations. This seriously affects the efficiency and safety of freight loading and unloading operations. It is urgent to study the lifting contact network to move the contact network horizontally and then lift it below the bottom of the vehicle body. Summary of the Invention

[0004] At present, related technologies have mentioned the tipping of columns. Direct tipping of columns needs to consider many factors, but there are still many technical problems to be overcome when used in the entire mobile contact network system. For example, the existing problems are:

[0005] 1. The existing technology directly tilts the arm by driving the column, and the tension on the load-bearing cable and the contact line will be converted into a torsion on the arm structure itself, which will cause the arm structure itself to deform.

[0006] 2. In this direct dumping method, the load-bearing cables and contact lines are prone to bending at the wrist arm fixing position, affecting their service life.

[0007] 3. The arm should tilt to the same degree as the column tilts. Due to the mechanical structure installation, temperature and other construction errors between the columns, there will be uneven tension between the columns.

[0008] 4. The original method of load-bearing cables and contact lines is prone to bending at the wrist arm fixing position, affecting the service life.

[0066] A third aspect of the present invention provides a method for operating a mobile contact network, comprising the following steps:

[0068] When the column is tilting or erecting, the column is rotationally connected to the rotation adjustment mechanism;

[0069] When the column is in the process of tilting or erecting, the arm support structure is driven to descend or ascend by the rotation adjustment mechanism, thereby driving the conductor to descend or ascend.

[0070] Preferably, the driving mechanism drives the column to tilt, and during the tilting process, the column is rotationally connected to the first shaft; the arm support structure remains substantially stationary;

[0071] During the tilting process of the column, the conductor on the arm support structure gradually descends while remaining substantially parallel to the ground;

[0072] After the pillars are tilted, the conductors are located at the side of the railway and are at least lower than the top of the train.

[0074] During the vertical process of the column, the conductor on the arm support structure gradually rises while remaining substantially parallel to the ground;

[0076] As a preference, the invention further comprises a conductor working position / non-working position switching driving mechanism to drive the arm support structure to rotate from the working position to the non-working position; or

[0077] Preferably, the conductor working position / non-working position switching drive mechanism drives the arm support structure to rotate from the non-working position to the working position, thereby driving the conductor to be located above the railway.

[0078] The present invention adopts the above technical solution and applies the column lifting and tilting drive device provided by the present invention to a mobile contact network. A number of columns are provided in the mobile contact network. The device of the present invention is used to drive the columns to tilt or stand upright through different driving mechanisms. Independent pushing structures can be used respectively, or a pulling member can be used to achieve overall control. In the process of using the pushing member, the other end of the pushing member can be independently controlled to move, or a pull rope can be used to achieve overall control. The pull rope is driven to move by the driving structure, and the other end of the pushing member acts directly or indirectly on the pull rope. In the process of the pull rope moving and driving the other end of the pushing member away from the column, the column gradually tilts; in the process of the pull rope moving and driving the other end of the pushing member close to the column, the column gradually stands upright. In this way, the lifting and lowering of the columns in the entire mobile contact network can be synchronously controlled by a single driving device. The synchronous movement of each column effectively ensures that the corresponding load-bearing cables and / or contact lines on each column are subjected to the same force, providing a guarantee for the smooth lifting and lowering of the load-bearing cables and / or contact lines. The present invention also has the following beneficial effects:

[0079] 1. To prevent bending of the catenary cables and / or contact wires during the tilting or vertical adjustment of the arm support structure, the present invention changes the conventional arrangement. During the tilting or vertical adjustment process, the column is pivotally connected to a first axis. This first axis then drives the arm support structure downward or upward, thereby driving the contact conductor downward or upward. This ensures that the conductor remains substantially parallel to the ground during the downward or vertical adjustment process.

[0080] 2. During the process of the arm support structure tilting or verticalizing, the catenary cables and contact lines maintain a relatively constant tension; the contact lines and catenary cables do not bend during the movement; the arm structure does not suffer from tension deformation; the catenary cables and contact lines can also be raised or lowered in a relatively parallel manner to the ground.

[0081] 3. The lifting and lowering of the columns in the entire mobile contact network can be synchronously controlled by a driving device. The synchronous movement of each column effectively ensures that the corresponding load-bearing cables and / or contact wires on each column are subjected to consistent force, providing a guarantee for the smooth lifting and lowering of the load-bearing cables and / or contact wires.

[0082] 4. By utilizing the combined effect of the counterweight structure and the lever structure, the center of gravity of the column is relatively constant during the tilting or vertical process, and can steadily drive the load-bearing cable and / or contact network to rise or fall; in addition, the external driving force device no longer bears too much of the changes in the gravity of the tiltable column itself, reducing the workload, and only requires less force to drive the tiltable column to a tilting state or a vertical state or to switch between the two states, which reduces the difficulty of system control, improves the stability of system operation, and provides safety protection for cargo loading and unloading.

[0083] 5. To prevent the bending of the catenary cables and / or contact wires during the tilting or vertical adjustment of the arm support structure, a rotation adjustment mechanism is provided to prevent the arm support structure from rotating during the tilting or vertical adjustment of the column. This technical feature is not disclosed in any existing related art. This mobile contact network was independently developed by the applicant and is a new and innovative product. This structure ensures that the contact conductor remains substantially parallel to the ground during the lowering or raising process.

[0084] 7. The additional rotation adjustment mechanism of the present invention is provided on the column. When the column is tilted, the arm support structure does not rotate, so that the contact conductor remains substantially parallel to the ground during the lowering or raising process.

[0085] 8. When the arm structure tilts or stands upright, the conductor working position / non-working position switching drive mechanism provides dragging force for the catenary and contact wire; the contact wire and catenary do not bend during the movement; the arm structure is not deformed by pulling; and the catenary contact wire can also be raised or lowered in a manner parallel to the ground.

[0086] 9. The present invention is more stable and reliable in driving, which improves the stability of system operation and provides safety guarantee for cargo loading and unloading. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0104] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, like numbers in different figures represent like or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present invention, as detailed in the appended claims.

[0105] like Figures 1 to 3 As shown, this embodiment provides a column 1 lifting and tilting drive device, which includes: a column 1, wherein the column 1 has a tilting state and a vertical state, or the column 1 can switch between the tilting and vertical states;

[0106] A driving mechanism is used to drive the column 1 to tilt, stand upright, or switch between the tilting and standing states.

[0107] This embodiment further includes a base structure 2 and a rotation fulcrum structure 3, and the column 1 is movably connected to the base structure 2 via the rotation fulcrum structure 3. It should be noted that the rotation fulcrum structure 3 in this embodiment is mainly used to facilitate the rotation of the column 1 on the base structure 2. The rotation fulcrum structure 3 can be any structure that can provide rotation, such as a rotation bearing or a rotation shaft, or a hole is opened in the base structure 2, and a rotation shaft is set on the column 1, and the rotation shaft rotates in the hole; as for the base structure 2 in this embodiment, its function is to support the column 1. The present invention does not impose any specific restrictions on the structure of the base, as long as the column 1 can rotate on the base structure 2.

[0108] The following embodiment provides several specific driving structures by category;

[0109] As a preferred embodiment, the driving mechanism for driving the column 1 to rise and tilt in this embodiment is implemented as follows: it includes a driving mechanism 4, and the driving mechanism 4 is used to drive the column 1 to tilt, stand upright, or switch between tilting and standing states.

[0110] It should be noted that the pushing mechanism 4 in this embodiment can be one or a combination of an electric push rod, a hydraulic push rod or a pneumatic push rod. The application scenario of one or more combinations is mainly when there are multiple columns 1 in the entire mobile contact network, and each column 1 has a corresponding driving mechanism. Some mechanisms can use electric push rods, while other columns 1 can use hydraulic push rods. This method is also possible.

[0111] As a preferred embodiment, the column 1 comprises a first body portion 5 and a second body portion 6. In this drive mode, the force provided by the drive mechanism can act on either the first body portion 5 (long arm) or the second body portion 6 (short arm). The force provided by the above embodiment acts on the first body portion 5; the force acting on the second body portion 6 works in a similar manner, because for a corresponding lever structure, either arm on either side of the driving fulcrum can achieve rotation.

[0112] In the above-mentioned method, each column 1 corresponds to a driving mechanism 4. Now, another driving method is provided, which is synchronous control. Only one pulling member 7 is needed to drive all the columns 1 to stand upright or tilt at the same time.

[0113] As a preferred embodiment, the driving mechanism for driving the column 1 to rise and tilt is implemented as follows: it includes a pulling member 7, and the pulling member 7 is used to pull the column 1 to tilt, stand upright, or switch between the tilting and upright states.

[0114] It also includes a device for driving the pulling member 7 to move, which includes a first pulling structure 8 and a second pulling structure 9. The force of the first pulling structure 8 acts on one end of the pulling member 7, and the force of the second pulling structure 9 acts on the other end of the pulling member 7.

[0115] In this embodiment, the pulling member 7 includes a pull rope, the first pulling structure 8 acts on one end of the pull rope, and the second pulling structure 9 acts on the other end of the pull rope.

[0116] In this way, the first pulling structure 8 and the second pulling structure 9 work together to move the pull rope, thereby driving the column 1 to tilt, stand upright, or switch between the tilting and standing states.

[0117] Two implementation scenarios are provided in this embodiment;

[0118] Case 1: The first pulling structure 8 and the second pulling structure 9 are both drag motors, and the two drag motors act on the two ends of the pull rope to drive the pull rope to move, thereby driving the column 1 to tilt, stand upright, or switch between tilting and standing states; in the case where both sides are drag motors, no drawings are provided, please refer to Figure 3 In the example, the pulling structure on the left can also use the drag motor on the right; or

[0119] Case 2: Attachment Figure 3 The corresponding diagram is a schematic diagram of using a pulling member to drive the column to a vertical state; Figure 4 It is a schematic diagram of the dumping state.

[0120] The first pulling structure 8 is a counterweight structure, and the second pulling structure 9 is a drag motor. The drag motor rotates in the positive direction to drive the pull rope to move, thereby driving the column 1 to tilt, stand upright, or switch between the tilting and upright states.

[0121] In this embodiment, a pull rope is used to drive all the columns 1 to rotate. As mentioned above, the column 1 in this embodiment has a first main body part 5 and a second main body part 6; therefore, the pulling member 7 (pull rope) can act on either side of the fulcrum, and the pull rope can be used to drive the long arm to rotate, and can also drive the short arm to rotate; but no matter whether it acts on the first main body part 5 or the second main body part 6, the pull rope acts on the column 1.

[0122] It is necessary to add that, if Figure 4 As shown, this embodiment further includes a rotating member 24, which can rotate on the column, and the pulling member 7 (pull rope) is installed on the column through the rotating member.

[0123] As another preferred embodiment, this embodiment does not provide drawings, but can refer to Figure 2 and 3 As shown, this embodiment is merely illustrative. In this embodiment, the column 1 comprises a first body portion 5 and a second body portion 6, which form a lever structure by rotating a fulcrum structure 3. When the weight of the second body portion 6 is greater than the weight of the first body portion, a pulling mechanism can be employed to pull the column 1. The implementation is as follows:

[0124] The pulling member 7 includes a pull rope, and the first pulling structure 8 acts on one end of the pull rope. The first pulling structure 8 pulls the pull rope to move, thereby driving the column 1 to tilt, stand upright, or switch between tilting and standing states. (In Figure 3On the basis of, assuming that there is no second structure 9), the first pulling structure in this embodiment can be a drag motor or a weight. However, if it is a weight, an additional pulling motor is required to lift or lower the weight. Back to this embodiment, the pull rope is applied to the top of the column 1 (the first main body part 5). When the column 1 needs to be tilted, the first pulling structure 8 is actuated to retract the pull rope, and the column 1 tilts; when the column 1 needs to be upright, the first pulling structure 8 is actuated to extend the pull rope. Since the weight of the second main body part 6 is greater than the weight of the first main body part 5, the column 1 gradually becomes upright.

[0125] See also Figure 5 and Figure 6 As shown in FIG. 1 , as a preferred embodiment, the driving mechanism for driving the column 1 to tilt up and down is implemented as follows: a pusher 10 is provided, wherein the pusher 10 is used to push the column 1 to tilt, stand upright, or switch between the tilted and upright positions. In this embodiment, the pusher 10 uses an inclined rod to support the column 1, and the operating state of the column 1 is changed by moving the pusher 10.

[0126] In this embodiment, one end of the pushing member 10 is movably connected to the column 1; it also includes a driving structure 11, which is used to drive the other end of the pushing member 10 to move, thereby driving the column 1 to tilt, stand upright, or switch between tilting and standing states.

[0127] It should be noted that the drive structure 11 in this embodiment includes one of an electric push rod, a hydraulic push rod, a pneumatic push rod, a sliding structure, a motor and chain combination, or a motor and gear combination, which drives the other end of the pusher 10 to move, thereby causing the column 1 to tilt, stand upright, or switch between tilting and standing positions. Regardless of the method used, as long as it can drive the other end of the pusher 10 to move, it will be sufficient. To clarify for those skilled in the art, it is now further explained that, for example, electric, hydraulic, or pneumatic structures can have their output shafts directly or indirectly act on the other end of the pusher 10 to cause it to move, and this will not be explained in detail here. A sliding structure refers to a structure in which the other end of the pusher 10 can move back and forth within the sliding structure. The motor and chain combination can be configured such that the motor drives the chain to rotate back and forth, directly or indirectly driving the other end of the pusher 10 to move. Similarly, the motor and gear combination can be configured such that the motor drives the gear to rotate, and the gear directly or indirectly drives the other end of the pusher 10 to move. These aforementioned embodiments are extensions of the present invention and are not provided with corresponding figures. These methods are to drive the columns 1 individually, and the synchronization of the state changes of the columns 1 can be ensured by controlling the synchronous actuation of the driving mechanisms.

[0128] Another integrally controlled driving solution is now provided. The driving structure 11 includes a pull rope 12. The driving structure 11 drives the pull rope 12 to move, thereby directly or indirectly driving the other end of the pushing member 10 to move.

[0129] The other end of the pushing member 10 acts directly or indirectly on the pull rope 12; in the process of the pull rope 12 moving and driving the other end of the pushing member 10 away from the column 1, the column 1 gradually tilts down; in the process of the pull rope 12 moving and driving the other end of the pushing member 10 close to the column 1, the column 1 gradually becomes upright.

[0130] To ensure smooth movement, this embodiment further includes a moving mechanism 13. The other end of the pusher 10 acts directly or indirectly on the moving mechanism 13. As the pull cord 12 moves the moving mechanism 13 away from the column 1, the column 1 gradually tilts. As the pull cord 12 moves the moving mechanism 13 toward the column 1, the column 1 gradually stands upright. A sliding moving trolley is one embodiment of the moving mechanism 13.

[0131] In order to ensure that the moving mechanism 13 moves smoothly and stably, a sliding track 14 is further provided in this embodiment. The moving mechanism 13 is provided on the sliding track 14 , and the movement of the pull rope drives the moving mechanism 13 to move on the sliding track 14 .

[0132] As a preferred embodiment with important features, if the pull rope is directly or indirectly fixed to the other end of the push member 10, a possible defect is that when a certain push member 10 is in place and the other push members 10 are not in place, the column 1 in the entire mobile contact network may fall over or not be upright in place.

[0133] Considering that one pull rope needs to push several columns 1 up and down, the other end of the pusher 10 corresponding to each column 1 needs to be fixed directly or indirectly on the pull rope. In order to facilitate the occurrence of a stuck phenomenon at a certain point to affect the overall pulling effect.

[0134] To solve this problem, a force transmission mechanism 15 is provided to transmit the pulling force of the pull rope to the moving mechanism 13, thereby driving the moving mechanism 13 to move. The force is transmitted by the elastic pusher 10. Even if a certain point becomes stuck, the pull rope can be pulled further without affecting the raising and lowering of the entire mobile contact network column 1.

[0135] The force transmission mechanism 15 includes an elastic pusher, one end of which is mounted on a pull cord. The pull cord moves to push or pull the elastic pusher, and the resulting pushing or pulling force acts directly or indirectly on the moving mechanism 13 through the elastic pusher. The applicant has submitted an application for separate protection of the force transmission mechanism 15, and will not be described in detail here.

[0136] As a preferred embodiment, it also includes a sleeve 16, which is arranged on the moving mechanism 13, and the pull rope is passed through the sleeve 16. One end of the elastic pusher is arranged on the pull rope, and a block is provided inside the sleeve 16 for bearing the force of the other end of the elastic pusher. The pull rope moves to push or pull the elastic pusher, and the resulting pushing force or pulling force is directly or indirectly acted on the sleeve 16 through the elastic pusher.

[0137] As a preferred embodiment, the elastic pusher in this embodiment can be a spring, and the number of the springs can be one or two.

[0138] like Figure 7 As shown, for example, two springs are set in the sleeve 16. Assuming that the pull rope moves to the left, the spring 17 on the left side of the sleeve 16 is compressed. The compressed spring transmits force to the sleeve 16, and the sleeve is fixed to the moving structure, thereby driving the other end of the pusher 10 connected to the column 1 to move to the left, lifting the column 1;

[0139] Similarly, the pull rope moves to the right, compressing spring 18 on the right side of sleeve 16. The compressed spring transmits force to sleeve 16, which is fixed to the movable structure, thereby driving the other end of pusher 10 connected to column 1 to move to the right, lowering column 1. The arrangement of the springs herein is merely an illustration of an implementation and does not limit the claims.

[0140] like Figure 6 As shown, in order to solve the problem of the movement of the pull rope, the driving structure 11 provided in this embodiment includes a first driving unit 111 and a second driving unit 112; the first driving unit 111 and the second driving unit 112 act directly or indirectly on the two ends of the pull rope to drive the pull rope to move. In this embodiment, the first driving unit 111 is a traction motor, and the second driving unit 112 is a weight; or the first driving unit 111 and the second driving unit 112 are both traction motors. The movement of the pull rope is driven by the joint action of the first and second driving units, and the movement of the pull rope directly or indirectly acts on one end of the pushing member 10 through the force transmission mechanism 15, so that it is pushed to move, thereby pushing or pulling the column 1 to change its state.

[0141] It should be noted that the drawings of this embodiment show that the force is applied to the long arm of the column 1. Of course, the above-mentioned method of pulling the pusher 10 with a pull rope can also act on the short arm.

[0142] Of course, it should be emphasized here that the second body part 6 is an optional component. Without the second body part, this driving scheme can also be fully realized. The driving scheme with the second body part 6 will be more stable. In this embodiment, the structural form of the column 1 itself is changed to make the column 1 rise and fall more smoothly. The first body part 5, the rotating fulcrum and the second body part 6 in this embodiment can be understood as a lever structure; in the absence of the second body part 6, the center of gravity of the column 1 changes during the process of tilting or verticalization, and its weight may gradually increase or decrease; this sudden change in weight requires an external driving mechanism to bear, but when using a pull rope to pull the entire column 1, or using a pull rope to pull the pusher 10, this sudden change in weight will bring additional workload to the pull rope.

[0143] Furthermore, in the prior art, during the tilting process, the center of gravity of the column 1 suddenly changes. The gravitational force exerted by the column 1 on the push-pull mechanism gradually increases from zero during the tilting process. This phenomenon not only forces the push-pull mechanism to bear the sudden workload, but also, since the column 1 is used to raise and lower the catenary cables and / or contact wires, this can cause the tilting process of the column 1 to be less than smooth.

[0144] To this end, a preferred embodiment is provided in which a second body portion 6 is added. The second body portion 6 can be integrally formed with the first body portion 5 or detachably connected. The second body portion 6 is mainly used to balance the lever and reduce the sudden change in weight during the tilting or vertical movement of the column 1.

[0145] By adjusting the mechanical structure of the column 1, the workload on the push-pull mechanism caused by the sudden change in the center of gravity during the column's tilting or erecting process is reduced. This avoids the problem of unstable driving caused by sudden load changes. The ultimate effect is that the column 1 can be tilted or erected with a relatively small external driving force.

[0146] like Figure 8 As shown, in order to further adapt, a counterweight structure 19 is further provided in this embodiment, and the counterweight structure 19 is directly or indirectly provided on the second body portion 6 of the column 1. The counterweight structure 19 here can be integrated with the second body portion 6, or can be suspended on the second body portion 6 by a rope, and the counterweight structure 19 can be composed of a detachable counterweight block.

[0147] Once again, it is necessary to expand on the explanation that the present embodiment also includes a counterweight structure 19, and the counterweight structure 19 is directly or indirectly arranged on the second body part 6 of the column 1. One way is to increase the weight of the second body part 6 as the counterweight structure 19; the other way is to hang a counterweight block on the second body part 6 on the basis of the first way. The purpose is to overcome the sudden change of the original center of gravity force through the cooperation of the counterweight structure 19 and the rotating fulcrum structure 3 during the tilting process of the column 1, so that the lifting and lowering are smoother; at the same time, the use of the lever structure only requires a smaller force to drive the column 1 to rise and fall. Such a drive motor (winch) can drive more columns 1, and the column 1 lifting and tilting drive device provided by the present invention can be used in long-distance mobile contact networks.

[0148] It should be added that, in this embodiment, the driving mechanism includes a first driving unit 111 and a second driving unit 112 ; the first driving unit 111 and the second driving unit 112 act directly or indirectly on both ends of the pull rope to drive the pull rope to move.

[0149] Furthermore, in the first solution, the first drive unit 111 is a traction motor, and the second drive unit 112 is a weight. In the second solution, the first and second drive units are both traction motors; one motor rotates forward and the other motor rotates reversely to drive the pull rope to move. As for how the wrist arm drives the load-bearing cable and the contact line to rotate above the railway or to the side of the railway, it is not the point protected by the present invention. A feasible way is to use a motor at one end of the mobile contact network and a weight at the other end of the mobile contact network, and drive the wrist arm to rotate above the railway or to the side of the railway through the cooperation of the motor and the weight.

[0150] like Figure 9 and Figure 10 As shown, the second aspect of this embodiment provides a mobile contact network, including the mobile contact network adopting the above-mentioned column 1 lifting and tilting drive device, and also including a cantilever support structure 20, a conductor, a first axis 21 and a second axis 22; the conductor in the present invention includes a load-bearing cable 24 and / or a contact wire 25, and the conductor shown in this embodiment includes a load-bearing cable and a contact wire.

[0151] The first shaft 21 is directly or indirectly arranged on the column 1. In this embodiment, the first shaft can be directly arranged on the column body, or can be arranged on the column body through the following method. Figure 10 The fixing member 27 is shown to be arranged on the column; the column 1 is rotationally connected to the first shaft 21; the rotation here refers to the rotation relationship between the column and the first shaft during the process of tilting or vertically adjusting the column.

[0152] The second shaft 22 is directly or indirectly disposed on the first shaft 21. In this embodiment, a wrist arm fixing base 23 is additionally provided. The wrist arm fixing base 23 is disposed on the first shaft 21, and the second shaft 22 is disposed on the wrist arm fixing base 23. The wrist arm support structure is directly or indirectly disposed on the second shaft 22; the conductor is directly or indirectly disposed on the wrist arm support structure 20. In this embodiment, the first shaft 21 is disposed horizontally, and the second shaft 22 is disposed vertically.

[0153] What needs to be explained here is the driving mechanism in the mobile contact network. Figure 9 The driving mechanism 4 or the pulling member 7 (pull rope) can be used to realize the driving. The driving member 10 shown in this embodiment is only for explanation and is not intended to limit the scope of protection of the present invention.

[0154] like Figures 11 to 14 As shown, on the other hand, the present invention provides a liftable and hidden mobile contact network, which includes several of the above-mentioned column lifting and tilting drive devices, and the pushing mechanism drives several columns or their corresponding columns to tilt or stand upright, or switch between the tilting and standing states, driving the conductor to rise or fall.

[0155] It should be noted that the contact network is divided into fixed contact network and mobile contact network. The solution of this embodiment specifically refers to the mobile contact network. The liftable and hidden mobile contact network provided by this embodiment is used in large-scale freight loading and unloading battlefields to provide electric drive for freight trains and 10,000-ton trains.

[0156] In this embodiment, the pillars 1 are tiltable pillars 1 , and each driving mechanism 4 drives the corresponding pillar 1 to tilt, stand upright, or switch between tilting and standing states, thereby driving the conductor to lower or rise.

[0157] In this embodiment, the conductor is driven to rise or fall by raising or lowering the column 1 , specifically by tilting or vertically adjusting the column 1 .

[0158] A further explanation is needed here. Conventional fixed contact networks, such as those used on high-speed rail lines, have contact wires 26 fixed above the railway. The high-speed rail's pantograph can draw power from the contact wires 26 by raising it. Conventional mobile contact networks move the catenary cables 25 and / or the contact wires 26 above the railway or to the side of the railway. However, since the sideways swing of the mobile contact network can affect cargo loading and unloading, it is necessary to develop a system that can lower the catenary cables 25, contact wires 26, and related support devices, columns 1, etc. below the height of the freight train, freeing up space above. This will facilitate the loading and unloading of freight trains, improve loading and unloading efficiency, and ensure loading and unloading safety.

[0159] In this embodiment, a conductor is also included; the conductor here includes a load-bearing cable 25 and / or a contact wire 26, and the conductor is used to provide electricity for the freight train.

[0160] The conductor in this embodiment has:

[0161] a working position state, in which the conductor is located above the railway;

[0162] A non-operating high position state, in which the conductor is located at the side of the railway and is higher than the top of the train; or

[0163] a non-operating low position state, in which the conductor is located at the side of the railway and is at least lower than the top of the train;

[0164] As a preferred embodiment, this embodiment further includes a conductor working position / non-working position switching drive mechanism 28;

[0165] The conductor working position / non-working position switching driving mechanism 28 is used to drive the conductor to switch between the working position and the non-working position.

[0166] In this embodiment, the conductor is in the non-working position, and when the pushing mechanism 4 drives the column 1 to be in a vertical state, the conductor is in the non-working high position state;

[0167] When the conductor is in the non-working position and the pushing mechanism 4 drives the column 1 to be in a tilting state, the conductor is in a non-working low position;

[0168] As a preferred embodiment, this embodiment further includes a cantilever support structure 20, which is rotatably disposed on the column 1; here, the cantilever support structure 20 is mainly used to support the conductor.

[0169] It should be noted that the traditional mobile contact network moves above the railway or to the side of the railway. In this embodiment, the spatial position relationship of the conductor is jointly controlled by the conductor working position / non-working position switching drive mechanism 28 and the pushing mechanism 4.

[0170] Therefore, the conductor in this innovative solution has a working state (above the railway); a non-working state (side of the railway) high state and a non-working state (side of the railway) low state.

[0171] The key and difficulty of this patent is that any time the catenary cable 25 is lowered from a high position to a low position, the process requires that the catenary cable 25 cannot be loose and must maintain tension; at the same time, the catenary cable 25 and the contact line 26 cannot be bent and must basically remain in a straight line; furthermore, the entire catenary cable 25 and the contact line 26 must be in a basically horizontal state when descending or ascending.

[0172] As an implementation method, this embodiment also includes a rotation adjustment mechanism A, and the arm support structure 20 is directly or indirectly movably connected to the rotation adjustment mechanism A; when the column 1 is in a tilted state, a vertical state, or when the column 1 switches between the tilted and vertical states, the arm support structure is driven to descend or rise, so that the contact conductor remains basically parallel to the ground during the lowering or rising process.

[0173] In this embodiment, the rotation adjustment mechanism A is directly mounted on the column body or mounted on the column via a fixing member, and the arm support structure is directly or indirectly mounted on the rotation adjustment mechanism. During the tilting or vertical adjustment of the column, the column and the rotation adjustment mechanism are rotationally connected; the conductor on the arm support structure gradually descends or ascends while remaining substantially parallel to the ground.

[0174] As a preferred embodiment, in this embodiment: the rotation adjustment mechanism A includes a first shaft 21, and when the column is tilting or erecting, the column 1 is rotationally connected to the first shaft 21, and the arm support structure 20 is directly or indirectly arranged on the first shaft 21.

[0175] In order to facilitate the cantilever support structure 20 to drive the load-bearing cable 25 and / or the contact line 26 to rotate between the working position and the non-working position, this embodiment further includes a second shaft 22. The first shaft 22 is directly or indirectly arranged on the first shaft 21. In this embodiment, the first shaft 21 is arranged horizontally, and the first shaft 22 is arranged vertically.

[0176] To facilitate installation of the arm support structure 20, this embodiment further includes an arm fixing base 23. The arm fixing base 23 is directly or indirectly mounted on the first shaft 21, and the second shaft 22 is directly or indirectly mounted on the rotating base. The arm support structure 20 is directly or indirectly mounted on the second shaft 22. When subjected to a thrust or pull force, the arm support structure can be rotated via the first shaft 22 to either a working position or a non-working position.

[0177] It should be noted that this embodiment also includes a wrist arm fixing seat 23, and the wrist arm support structure 20 of the rotating member can also be directly or indirectly disposed on the wrist arm fixing seat 23. In this embodiment, during the process of descending or ascending, the column is rotatably connected to the first shaft 21, and the first shaft 21 itself does not rotate. The wrist arm support structure 20 is disposed on the first shaft 21, which can effectively ensure that the entire load-bearing cable 25 and the contact wire 26 remain substantially in a straight line during the ascending or descending process, and will not bend or other undesirable phenomena. At the same time, the cooperation with the conductor working position / non-working position switching drive mechanism 28 can ensure that the load-bearing cable 25 and the contact wire 26 remain substantially parallel to the ground during the ascending or descending process.

[0178] like Figure 11 As shown, this embodiment further includes a base structure 2, and the column is movably connected to the base structure 2. The column 1 is driven to tilt, stand upright, or switch between the tilting and standing states by a pushing mechanism 4.

[0179] In this embodiment, each of the push mechanisms 4 extends to drive the corresponding column toward an upright position, and each of the push mechanisms 4 retracts to drive the corresponding column toward a tilted position. The column tilting and vertical drive mechanisms utilize a drive element that drives the corresponding column to tilt, vertically, or switch between the tilting and vertical positions. Preferably, the drive element comprises an electrically driven push rod, an electric push rod, a hydraulic push rod, or a pneumatic push rod.

[0180] As a preferred embodiment, the conductor working position / non-working position switching drive mechanism in this embodiment includes a dragging mechanism 281 and a counterweight structure 19; the dragging mechanism 281 is directly or indirectly arranged at one end of the conductor, and the counterweight structure 19 is directly or indirectly arranged at the other end of the conductor.

[0181] It should be noted that the dragging mechanism in this embodiment is configured as follows:

[0182] First: Please refer to Figure 11, the dragging mechanism is arranged on a tiltable column, the dragging mechanism rises and falls with the column, and during the process of tilting or vertically erecting the column, the dragging mechanism provides a dragging force for the conductor; or

[0183] The second embodiment: (this embodiment is not shown in the figure) a tiltable column is provided, on which a guide wheel is provided, and the conductor passes through the insulator, bypasses the guide wheel and extends to act on the dragging mechanism.

[0184] The third type: (this embodiment is not shown in the figure) a column is set, a moving cart is set on the column, the dragging mechanism is set on the moving cart, and while the dragging mechanism provides dragging force for the conductor, the moving cart drives the dragging mechanism to rise or fall with the conductor.

[0185] The counterweight structure in this embodiment is arranged as follows:

[0186] The first method: (this embodiment is not shown in the figure) a tiltable column is provided, wherein the column is provided with a guide wheel, and the conductor passes through the insulator, bypasses the guide wheel and extends to act on the counterweight structure 19; or

[0187] Second: Please refer to Figure 11 On the basis of the first structure, another guide wheel is provided; the conductor passes through the insulator, bypasses the guide wheel 29 on the column, and then extends around another guide wheel to act on the counterweight structure 19.

[0188] In this embodiment, the conductors include load-bearing cables 25 and / or contact wires 26 , and the conductors are directly or indirectly disposed on the arm support structure 20 .

[0189] As a preferred embodiment, this embodiment further includes a force transmission mechanism 15. In this embodiment, the force transmission mechanism 15 is disposed on the arm support structure 20. The force transmission mechanism 15 is used to transmit the tension or thrust exerted on the load-bearing cable 25 and / or contact wire 26 to the arm support structure 20, thereby driving the arm support structure 20 to rotate to a working position or a non-working position, or to switch between the working and non-working positions. The applicant has separately applied for patent protection for the force transmission mechanism, and reference is made to prior documents, so this description is omitted here.

[0190] like Figure 15 As shown, the third aspect of this embodiment provides a method for operating a mobile contact network. The operating method adopts the above-mentioned mobile contact network, and the operating steps are as follows:

[0191] The driving mechanism is used to drive the column 1 to switch between the tilted state and the upright state;

[0192] When the column 1 is tilting or erecting, the column 1 is rotationally connected to the rotation adjustment mechanism A;

[0193] When the column 1 is tilting or erecting, the rotation adjustment mechanism A drives the arm support structure 20 to descend or ascend, thereby driving the conductor to descend or ascend.

[0194] Here are two specific operation methods:

[0195] The first method is a method for operating a liftable hidden mobile contact network, which uses the liftable hidden mobile contact network described above and includes the following steps:

[0196] The conductor working position / non-working position switching drive mechanism drives the arm support structure to rotate from the working position to the non-working position;

[0197] The column tilting vertical drive mechanism drives the column to tilt. During the tilting process, the column is rotationally connected to the rotation adjustment mechanism (first shaft 21); the arm support structure does not rotate.

[0198] During the tilting process of the column, the conductor on the arm support structure gradually descends while remaining substantially parallel to the ground;

[0199] After the pillars are tilted, the conductors are located at the side of the railway and are at least lower than the top of the train.

[0200] The second method is a method for operating a liftable hidden mobile contact network, which uses the liftable hidden mobile contact network described above and includes the following steps:

[0201] The column tilting and vertical driving mechanism drives the column to be vertical. During the vertical process, the column is rotationally connected to the rotation adjustment mechanism (first shaft 21); the arm support structure does not rotate.

[0202] During the vertical process of the column, the conductor on the arm support structure gradually rises while remaining substantially parallel to the ground;

[0203] After the upright post is erected, the conductor is located on the side of the railway and is higher than the top of the train;

[0204] The conductor working position / non-working position switching driving mechanism drives the arm support structure to rotate from the non-working position to the working position, thereby driving the conductor to be located above the railway.

[0205] The working principle of the actuation of the aspect part has been described in detail above and is quoted here without repetition.

[0206] In the prior art, the arm support structure 20 is rotatably mounted on the column 1, and the arm support structure 20 swings to the top of the railway (working position), or swings to the side of the railway (non-working position). In the present invention, the column 1 needs to be tilted. The advantage of tilting is that it drives the entire mobile contact to descend to the ground, freeing up the space above, which is beneficial for cargo loading and unloading, providing a larger cargo loading and unloading space, and at the same time reducing the damage caused by the lifting equipment touching the mobile contact network during the original cargo loading and unloading process, such as touching the contact line, the arm structure, etc. Therefore, tilting the column 1 has great benefits. However, no specific implementation plan is given in the existing related technology, so the present invention provides a new hidden mobile contact network,

[0207] The biggest problem in the existing technology is that during the tilting of the column 1, the arm structure also has to tilt to a corresponding angle. Therefore, the biggest problem that needs to be solved is: during the tilting of the column 1, the arm structure remains relatively fixed, so that the load-bearing cable and / or the contact line remain basically parallel to the ground during the rising or falling process. For this purpose, it is necessary to provide a new structure, such as the first axis 21 added in the present invention, and the first axis 21 is arranged on the column 1. During the tilting of the column 1, the column 1 is rotationally connected to the first axis 21, and the tension of the load-bearing cable and the contact line acts on the arm support structure 20, which is equivalent to providing a balanced pulling force to the arm support structure 20 from both ends. The root of the arm support structure 20 is directly or indirectly arranged on the first axis 21, and the column 1 is rotationally connected to the first axis 21. Therefore, during the tilting or verticalization of the column 1, the arm support structure 20 will not tilt.

[0208] The present invention effectively overcomes the shortcomings of existing technologies. During the tilting or vertical adjustment of the arm support structure 20, the columns are pivotally connected to the first shaft 21, allowing the columns to tilt or vertically adjust. During this process, the first shaft 21 itself does not rotate, thus preventing the arm support structure from rotating. As the columns rise or fall, they also drive the catenary cables and / or contact wires upward or downward. During the tilting or vertical adjustment of the columns in the mobile contact network, the conductor's active / inactive position switching drive mechanism continuously applies tension to the conductors. This tensioned conductor, in other words, can pull or drag the arm support structure. Most importantly, the conductors can provide power to the freight train when in the active position, allowing the pantograph to be raised to draw power. When the conductors are in the inactive position, any movement of the arm support structure will have no impact and can be ignored. In this embodiment, the catenary cables 25 and contact wire 26 maintain relatively constant tension. During movement, the contact wire 26 and catenary cables 25 are prevented from bending due to the arm's tilting. Because the present invention prevents the arm support structure from tilting, the arm support structure remains stable. The problem of the original arm support structure being deformed by pulling is overcome; the load-bearing cable 25 and the contact line 26 can also be raised or lowered in a relatively parallel manner to the ground; the drive is reliable and the operation is more stable, which improves the stability of the system operation and provides safety for cargo loading and unloading.

[0209] The adoption of the present invention can effectively overcome the shortcomings of the existing related technologies. During the process of the arm support structure 20 tilting or vertically, the load-bearing cables and the contact line maintain a relatively constant tension; the contact line and the load-bearing cables do not bend during the movement; the arm structure is not deformed by tension; and the load-bearing cables and the contact line can also be raised or lowered in a manner relatively parallel to the ground.

[0210] Although the embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are exemplary and are not to be construed as limitations on the present invention. A person skilled in the art may change, modify, replace and modify the above embodiments within the scope of the present invention.
