Description

Technical Field

[0001] This invention relates to the field of magnetic levitation train maintenance, and in particular to a magnetic levitation train transfer method and a mobile train lifting machine. Background Technology

[0002] Maglev trains are a modern, high-tech rail transit system that uses electromagnetic force to achieve contactless levitation and guidance between the train and the track, and utilizes electromagnetic force generated by a linear motor to propel the train. Maglev vehicles have no direct mechanical contact with the track, are not limited by the traditional wheel-rail adhesion limit, and have advantages such as low vibration and noise, smooth operation, small turning radius, and strong climbing ability.

[0003] Currently, the maintenance model for maglev trains, in addition to fixed maintenance procedures such as lean repair and fault repair, also requires a comprehensive overhaul every 7 years or approximately 1.4 million kilometers. Due to the small gap between the maglev train car body and the suspension frame, the existing mobile car-lifting machine's support head cannot be inserted between the car body and the suspension frame, making it difficult to transport the car body. Therefore, overhead cranes with specialized lifting equipment are typically used to transport the disassembled car body. This requires a high-height maintenance depot, and the transportation is difficult and prone to safety accidents. Summary of the Invention

[0004] The purpose of this invention is to provide a method for transporting maglev trains, in order to solve the technical problems of high requirements for the height of the maintenance depot and the difficulty of transporting maglev train bodies by overhead crane.

[0020] S3.3 The mobile car-lifting machine controls the lifting head to raise a single car body to a set height;

[0021] S3.4 The mobile car-lifting machine moves a single car body along the first track to the car-moving platform;

[0022] S3.5 The mobile car-lifting machine controls the lowering of the jack head to lower a single car body onto the car-moving platform.

[0023] Preferably, each set of mobile car-lifting machines includes four mobile car-lifting machines.

[0024] The purpose of this invention is to provide a mobile vehicle jacking machine to solve the technical problem that existing mobile vehicle jacking machines are difficult to use for transporting maglev train bodies.

[0025] A mobile jacking machine, controlled using the aforementioned magnetic levitation train transfer method, comprises:

[0026] The movable base allows it to move along the track;

[0027] The support frame is connected at one end to the movable base;

[0028] The lifting mechanism includes a drive assembly, a lead screw, and a support head assembly. The drive assembly is located at the other end of the support frame. One end of the lead screw is rotatably connected to the support frame and connected to the output end of the drive assembly. The support head assembly includes a connecting rod, a support rod, and two support plates. The two support plates are located at both ends of the support rod. One end of the connecting rod is connected to the support rod, and the support rod is movable along the length of the connecting rod. The other end of the connecting rod is screwed to the lead screw. The drive assembly can drive the lead screw to rotate around its own axis, thereby moving the support head assembly along the axis of the lead screw.

[0029] Preferably, the lifting mechanism further includes a first load-bearing component, which includes two connecting plates, two front load-bearing wheels, and two rear load-bearing wheels. The support frame includes two support columns. The two connecting plates are respectively fixedly disposed on both sides of the connecting rod. The two front load-bearing wheels are respectively disposed at one end of the two connecting plates and are respectively rolledly connected to one side of the two support columns. The two rear load-bearing wheels are respectively disposed at the other end of the two connecting plates and are respectively rolledly connected to the other side of the two support columns. The height of the two rear load-bearing wheels is higher than the height of the two front load-bearing wheels.

[0030] Preferably, the lifting mechanism further includes a second bearing component. Guide grooves are provided on the side of each of the two support columns near the connecting plate. The second bearing component includes a bearing rod and a guide wheel. One end of the bearing rod is connected to the connecting plate, and the other end of the bearing rod is rotatably connected to the guide wheel. The guide wheel can move along the guide groove. A second bearing component is provided at both the upper and lower ends of the two connecting plates.

[0031] Preferably, the support assembly further includes a movable rod, the connecting rod is provided with a receiving cavity, one end of the movable rod is slidably disposed in the receiving cavity, and the other end of the movable rod is connected to the support rod.

[0032] Preferably, the movable base includes a support, a pulley, and a second driving member. The pulley is rotatably connected to the movable base and to the track. The second driving member is connected to the support and is configured to drive the pulley to rotate around its own axis and move the base along the track.

[0033] Beneficial effects: This invention provides a method for transporting maglev trains. A mobile lifting machine lifts a single car body and moves it to a transfer platform via a first track. The car body is then moved to a second track via the transfer platform, and finally moved to a maintenance platform via another set of mobile lifting machines on the second track. This method avoids the use of overhead cranes to lift single car bodies, allowing the entire transport process to be ground-based, making the transport more stable and safer. Furthermore, the use of mobile lifting machines effectively reduces the height requirements of the maintenance depot, thus reducing the difficulty and cost of transporting maglev trains.

[0034] This invention also provides a mobile jacking machine, controlled using the aforementioned maglev train transport method. The mobile jacking machine includes a mobile base, a support frame, and a lifting mechanism. When lifting a single car body, the mobile jacking machine is first moved to the car body location via the mobile base. Two support plates are aligned with the two jacking points of the car body. Then, the support rod is moved towards the car body so that the support plates are below the jacking points. The drive assembly is activated, causing the lead screw to rotate and drive the support head assembly upwards, thus raising the car body. By setting support plates at both ends of the support rod, more jacking points can be used during the lifting process, making the lifting more stable. Simultaneously, the support plates can easily and quickly extend into the gap between the car body and the suspension frame, solving the problem of existing mobile jacking machines being unable to extend into the gap between the car body and the suspension frame. This allows the mobile jacking machine to be applied to the transport of maglev trains, enabling maglev trains to be transported based on the ground, reducing the height requirements of the maintenance depot, and lowering the difficulty and cost of transporting maglev trains.

It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0055] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0056] Maglev trains are a modern, high-tech rail transit system that uses electromagnetic force to achieve contactless levitation and guidance between the train and the track, and utilizes electromagnetic force generated by a linear motor to propel the train. Maglev vehicles have no direct mechanical contact with the track, are not limited by the traditional wheel-rail adhesion limit, and have advantages such as low vibration and noise, smooth operation, small turning radius, and strong climbing ability.

[0057] Currently, the maintenance model for maglev trains, in addition to fixed maintenance procedures such as lean repair and fault repair, also requires a comprehensive overhaul every 7 years or approximately 1.4 million kilometers. Due to the small gap between the maglev train car body and the suspension frame, the lifting head of existing mobile lifting machines cannot be inserted between the car body and the suspension frame, making it difficult to transport the car body. Therefore, overhead cranes with specialized lifting equipment are typically used to transport the disassembled car body, which requires a high-height maintenance depot, is difficult to operate, and is prone to safety accidents. Therefore, this embodiment provides a maglev train transport method and a mobile lifting machine to solve the above problems.

[0058] refer to Figures 1-3 This embodiment provides a mobile car-lifting machine 1, which includes a mobile base 11, a support frame 12, and a lifting mechanism. The mobile base 11 allows the mobile car-lifting machine 1 to move on the track, and the support frame 12 supports the lifting mechanism. The lifting mechanism can lift a single car body to complete the transfer of the maglev train 2, avoiding the need to use an overhead crane to hoist the maglev train 2. The entire transfer process is completed on the ground, making the transfer operation safer.

[0059] Specifically, the movable base 11 can move along the track; one end of the support frame 12 is connected to the movable base 11; the lifting mechanism includes a drive assembly 131, a lead screw 132, and a support head assembly 133. The drive assembly 131 is located at the other end of the support frame 12. One end of the lead screw 132 is rotatably connected to the support frame 12 and connected to the output end of the drive assembly 131. The support head assembly 133 includes a connecting rod 1331, a support rod 1332, and two support plates 1333. The two support plates 1333 are located at both ends of the support rod 1332. One end of the connecting rod 1331 is connected to the support rod 1332. The support rod 1332 can move along the length of the connecting rod 1331. The other end of the connecting rod 1331 is screwed to the lead screw 132. The drive assembly 131 can drive the lead screw 132 to rotate around its own axis, thereby driving the support head assembly 133 to move along the axis of the lead screw 132.

[0060] When lifting a single car body, the mobile lifting machine 1 is first moved to the single car body via the movable base 11. The two support plates 1333 are aligned with the two lifting points of the single car body. Then, the support rod 1332 is moved towards the single car body so that the support plates 1333 are below the lifting points. The drive assembly 131 is activated to rotate the lead screw 132 and drive the support head assembly 133 to move upward, thus raising the single car body. By setting support plates 1333 at both ends of the support rod 1332, more lifting points can be used during the lifting process, making the lifting more stable. At the same time, the support plates 1333 can be easily and quickly inserted into the gap between the single car body and the suspension frame, solving the problem that the existing mobile lifting machine 1 is difficult to insert into the gap between the single car body and the suspension frame. This allows the mobile lifting machine 1 to be used for the transfer of the maglev train 2, enabling the maglev train 2 to be transferred based on the ground, reducing the height requirements of the maintenance depot, and reducing the difficulty and cost of transferring the maglev train 2.

[0061] Specifically, the drive assembly 131 includes a first drive member 1311 and a reducer 1312. Both the first drive member 1311 and the reducer 1312 are located at the top of the support frame 12. The first drive member 1311 is connected to the lead screw 132 through the reducer 1312, so that the lead screw 132 can rotate slowly to drive the support head assembly 133 to move.

[0062] There is no limitation on the type of the first driving component 1311. In this embodiment, the driving component 131 is a servo motor, which can accurately control the movement of the support head component 133 according to the signal to ensure safety when transporting a single car body.

[0063] Specifically, the support assembly 133 also includes a movable rod. The connecting rod 1331 is provided with a receiving cavity. One end of the movable rod is slidably disposed in the receiving cavity, and the other end of the movable rod is connected to the support rod 1332. Before lifting a single car body, the mobile car lifting machine 1 moves on both sides of the maglev train 2. When the mobile car lifting machine 1 moves to both sides of the maglev train 2, the support rod 1332 needs to be moved toward the maglev train 2 so that the support plate 1333 can be located below the car lifting point.

[0064] Furthermore, the lifting mechanism also includes a first load-bearing component 134, which includes two connecting plates 1341, two front load-bearing wheels 1342 and two rear load-bearing wheels 1343. The support frame 12 includes two support columns 121. The two connecting plates 1341 are respectively fixedly disposed on both sides of the connecting rod 1331. The two front load-bearing wheels 1342 are respectively disposed at one end of the two connecting plates 1341 and are respectively tumblingly connected to one side of the two support columns 121. The two rear load-bearing wheels 1343 are respectively disposed at the other end of the two connecting plates 1341 and are respectively tumblingly connected to the other side of the two support columns 121. The height of the two rear load-bearing wheels 1343 is higher than the height of the two front load-bearing wheels 1342.

[0065] When lifting a single section of the vehicle body, the lifting head assembly 133 is subjected to a first torque by the single section of the vehicle body. The first torque is transmitted to the support column 121 by setting the front bearing wheel 1342 and the bearing wheel, avoiding the torque being borne by the connecting rod 1331 and the moving rod, making the process of lifting the single section of the vehicle body more stable and safe.

[0066] Specifically, the first bearing assembly 134 also includes two rotating shafts 1344, which are disposed between two connecting plates 1341. The two ends of the rotating shafts 1344 pass through the connecting plates 1341 and are connected to the front bearing wheel 1342 or the rear bearing wheel 1343. When the support assembly 133 drives the single car body to rise, the front bearing wheel 1342 and the rear bearing wheel 1343 can roll closely against the surface of the support column 121, making the movement of the support assembly 133 smoother.

[0067] Furthermore, the lifting mechanism also includes a second bearing assembly 135. Guide grooves are provided on the side of each of the two support columns 121 near the connecting plate 1341. The second bearing assembly 135 includes a bearing rod 1351 and a guide wheel 1352. One end of the bearing rod 1351 is connected to the connecting plate 1341, and the other end of the bearing rod 1351 is rotatably connected to the guide wheel 1352. The guide wheel 1352 can move along the guide groove. A second bearing assembly 135 is provided at both the upper and lower ends of the two connecting plates 1341.

[0068] Because support plates 1333 are provided at both ends of the support rod 1332, a second torque is generated when lifting a single section of the vehicle body. By providing second load-bearing components 135 at the upper and lower ends of the two connecting plates 1341, the guide wheel 1352 and the load-bearing rod 1351 transmit the second torque to the support column 121. At the same time, the guide groove provided on the support column 121 enables the guide wheel 1352 to play a guiding role, making the lifting process more stable and safe.

[0069] Specifically, the movable base 11 includes a support base 111, a pulley 112, and a second driving member. The pulley 112 is rotatably connected to the movable base 11 and connected to the track. The second driving member is connected to the support base 111 and is configured to drive the pulley 112 to rotate around its own axis and drive the base to move along the track.

[0070] There is no limitation on the number of pulleys 112. In this embodiment, four pulleys 112 are provided, with two connected to each track, so that the mobile base 11 is stably supported and slides smoothly.

[0071] There is no restriction on the specific type of the second driving component. In this embodiment, the second driving component is a motor. The output end of the second driving component is connected to four pulleys 112 through a gear set, and controls the rotation of the four pulleys 112 at the same time.

[0072] refer to Figures 4-5 This embodiment also provides a method for transferring maglev train 2, including:

[0073] S1. Disassemble and separate the car body assembly and suspension frame of the maglev train 2;

[0074] S2. Decompose the entire train body into individual car sections;

[0075] S3. A single car body is lifted by a set of mobile car lifting machines 1. The mobile car lifting machines 1 drive the single car body to move along the first track 3 to the car transfer platform 4 and place the single car body on the car transfer platform 4.

[0076] S4, the car transfer platform 4 moves the single car body to the second track 5;

[0077] S5. Another set of mobile car-lifting machines 1 moves a single car body to the maintenance platform 7 along the second track 5.

[0078] S6. Repeat S3-S5 until all the single car body sections are transferred to the maintenance bench 7 for repair.

[0079] A single car body is lifted by a mobile lifting machine 1 and moved to a transfer platform 4 via the first track 3. The car body is then moved to the second track 5 via the transfer platform 4, and then moved to the maintenance platform 7 via another set of mobile lifting machines 1 on the second track 5. This avoids the need to use an overhead crane to lift the car body, allowing the entire transfer process of the car body to be based on the ground, making the transfer more stable and safer. In addition, the use of mobile lifting machines 1 can effectively reduce the height requirements of the maintenance depot, and reduce the difficulty and cost of transferring the maglev train 2.

[0080] There is no limit to the number of mobile jacking machines 1 in each group. In this embodiment, each group includes four mobile jacking machines 1, and two mobile jacking machines 1 are set on both sides of a single car body, which can carry out stable and safe operation and meet the needs of eight jacking points for a single car body. In other embodiments, the number of mobile jacking machines 1 should be set according to the needs of a single car body.

[0081] Furthermore, preceding S1 includes:

[0082] After the maglev train 2 enters the maintenance depot, the power supply is cut off, allowing the suspension frame to rest on the floating track to ensure operational safety.

[0083] Specifically, S1 includes:

[0084] Disassemble the air springs, connecting pipes, and wires between the body assembly and the suspension frame to completely disconnect the body assembly from the suspension frame.

[0085] Specifically, S3 includes:

[0086] S3.1 Move a set of mobile car-lifting machines 1 along the first track 3 to the corresponding position of the driving point;

[0087] S3.2, make the support head assembly 133 of the mobile car-lifting machine 1 extend between the single car body and the suspension frame;

[0088] S3.3, The mobile car lifting machine 1 controls the lifting head to raise a single car body to a set height;

[0089] S3.4 The mobile car-lifting machine 1 drives a single car body to move along the first track 3 to the car-moving platform 4;

[0090] S3.5, The mobile car-lifting machine 1 controls the lowering of the support head to lower a single car body onto the car-moving platform 4.

[0091] There is no limitation on the lifting height of a single car body. In this embodiment, the single car body is raised by 10mm to avoid collision with components such as the suspension frame. In other embodiments, the single car body should be raised by 10-15mm to ensure the smooth progress of the transfer process.

[0092] Specifically, the transfer platform 4 is mainly used for parallel track switching operations of subway vehicles, EMUs, railcars, etc. In this embodiment, the transfer platform 4 is equipped with two auxiliary tracks 41, so that the mobile car lifting machine 1 on both sides of the single car body can drive the single car body directly from the first track 3 to the auxiliary track 41, so as to move the single car body to the position of the transfer platform 4.

[0093] Several rail-changing tracks 42 are set below the car-moving platform 4. The rail-changing tracks 42 are set perpendicular to the first track 3. The car-moving platform 4 can move along the rail-changing tracks 42 and connect the auxiliary track 41 with the second track 5, in preparation for the subsequent movement of a single car body by another set of mobile car-lifting machines 1.

[0094] Furthermore, following S3.5:

[0095] S3.6, a set of mobile car-lifting machines 1 moves along the first track 3 to another single car body to prepare for the next single car body lifting operation. Since another set of mobile car-lifting machines 1 is set on the second track 5 to move the single car body to the transfer platform 4 and then to the maintenance platform 7, the mobile car-lifting machines 1 on the first track 3 can return to another single car body to prepare for the next single car body lifting operation, thus speeding up the transfer operation efficiency.

[0096] Furthermore, following S3.6, it also includes:

[0097] S3.7 Push the suspension frame along the floating rail to the suspension frame working platform 6.

[0098] When one car body moves back to another car body, the suspension frame under the previous car body can be pushed along the floating rail to the suspension frame dropping platform 6 at the end of the floating rail. The suspension frame dropping platform 6 includes multiple hydraulic cylinders, which can make the platform height at the top of the suspension frame dropping platform 6 slightly lower than the floating rail. The suspension frame can be smoothly pushed from the floating rail to the suspension frame dropping platform 6, and then transferred to other working platforms by forklifts or other transfer tools.

[0099] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
