Description

Technical Field

[0001] This application relates to the field of railway electric multiple unit (EMU) manufacturing, and in particular to a rail-crossing vehicle transfer machine and an EMU assembly platform. Background Technology

[0002] On the assembly line-style train assembly line, there are three tracks in the workshop: a middle track for transfer and two side tracks for assembly stations. Eight assembly stations are arranged sequentially along the side tracks. After the car body is transported from the east end to the west end of the workshop along the middle track, a 20-ton double overhead crane lifts the 10-ton car body to the side tracks. However, when entering the A4 maintenance process, the interior and equipment of the car body are not completely removed, and the car body's weight reaches 40 tons. Therefore, the 20-ton double overhead crane cannot lift the 40-ton car body to the side assembly station tracks.

[0003] Replacing the overhead crane with one of greater lifting capacity or adding an indoor pit-type traction platform can solve the problem of changing the crane track. However, replacing it with an overhead crane with one of greater lifting capacity would require the existing crane tracks in the workshop to be unable to bear the load, and the factory structure would also need to be modified, which would be time-consuming and costly. Another option is to add a pit-type traction platform, which would require digging a pit in the workshop. However, having a pit in the workshop would affect personnel operations and logistics transportation, which would be detrimental to production organization. In addition, the purchase cost of the traction platform would also be high and the development process would be long. Summary of the Invention

[0022] First embodiment: according to Figure 1-7As shown, the first embodiment discloses a track-crossing vehicle transfer machine 1, which is disposed below the dummy trolley 2. The track-crossing vehicle transfer machine 1 includes a frame 6, a lifting device 9, and a vehicle-machine moving device 10. The lifting device 9 is disposed on the frame 6 and is used to adjust the height of the dummy trolley 2 in the vertical direction. The vehicle-machine moving device 10 is also disposed on the frame 6 for moving the track-crossing vehicle transfer machine 1.

[0023] The lifting device 9 is used to perform a back-and-forth lifting action in the vertical direction to adjust the height of the dummy trolley 2 in the vertical direction. The vehicle moving device 10 is a moving part. Moreover, the track moving machine 1 is adapted to the connecting track 5 so that the track moving machine 1 can move back and forth on the connecting track 5.

[0024] With the above solution, when the rail-crossing transfer machine 1 carries the car body 3, the rail-crossing transfer machine 1 can lift the dummy trolley 2 away from the platform through the lifting device 9, thereby avoiding collision between the dummy trolley 2 and the platform. Then, the rail-crossing transfer machine 1 can move its position through the car-machine moving device 10, thereby moving the dummy trolley 2 to a different position. This allows the car body 3 to be moved quickly to change tracks without significantly altering the factory structure, without affecting personnel passage and operations, ensuring smooth logistics in the workshop, reducing project costs, and compared to the previous method of using overhead cranes, it eliminates the need to install lifting equipment each time, greatly reducing the labor intensity of workers and improving production efficiency.

[0025] The platform can be either ground or a workbench; this embodiment is not limited as long as it meets the requirements of this embodiment. The dummy trolley 2 is used to carry the vehicle body 3, which can be any rail vehicle such as a locomotive, EMU, high-speed rail, or maglev train. The number of assembly tracks 4 is set to at least two, and all assembly tracks 4 are laid on the platform. Each assembly track 4 is adapted to the dummy trolley 2. The transfer track 41 is laid on the platform and located between adjacent assembly tracks 4. The transfer track 41 is adapted to the dummy trolley 2. The connecting track 5 is also laid on the platform and connects the transfer track 41 and the assembly track 4. The rail-crossing vehicle transfer machine 1 is adapted to the connecting track 5.

[0026] Based on any of the above embodiments, the lifting device 9 can be exemplaryly configured as follows: The lifting device 9 includes a lifting power structure 13 and a lifting plate 15.

[0027] One side of the lifting plate 15 is connected to the power output end of the lifting power structure 13, and the other side is used to abut against the dummy trolley 2 when lifting the dummy trolley 2. The power output end of the lifting power structure 13 is connected to one side of the lifting plate 15, which is used to drive the lifting plate 15 to move back and forth in the vertical direction, thereby adjusting the height of the dummy trolley 2 in the vertical direction by raising and lowering the position of the dummy trolley 2.

[0028] In addition, the following settings can be made for the lifting plate 15: the shape and size of the lifting plate 15 are matched with the adapter hole opened on the upper surface of the frame 6, and the power output end of the lifting power structure 13 is connected to one side of the lifting plate 15 (i.e., the lower surface of the lifting plate 15). When the rail-crossing transfer machine 1 does not need to lift the dummy trolley 2, the lifting plate 15 is set in the adapter hole and the upper surface of the lifting plate 15 is flush with the upper surface of the frame 6. When the rail-crossing transfer machine 1 needs to lift the dummy trolley 2, the lifting power structure 13 outputs power from bottom to top to lift the lifting plate 15, thereby lifting the dummy trolley 2 to increase the distance between the dummy trolley 2 and the platform. Of course, during the lifting stage of the dummy trolley 2, if it is necessary to reduce the distance between the dummy trolley 2 and the platform, the lifting power structure 13 will reduce the power output or output the lifting force in the opposite direction, so that the lifting plate 15 moves downward until the lifting plate 15 is reset in the adapter hole and the upper surface of the lifting plate 15 is flush with the upper surface of the frame 6.

[0029] Of course, to ensure the stability of the lifting power structure 13 during the process of lifting the lifting plate 15 and to avoid deviation in the lifting direction, the following settings are made in another embodiment: The lifting device 9 further includes a guide structure disposed between the lifting plate 15 and the lifting power structure 13. The guide structure is parallel to the power direction of the lifting power structure (13) and is used to vertically guide the power output by the lifting power structure 13.

[0030] Specifically, the guide structure includes a guide sleeve 17 and a guide post 16. The guide post 16 is disposed inside the guide sleeve 17 and can move back and forth along the length direction of the guide sleeve 17. The length direction of the guide sleeve 17 is parallel to the power output direction of the lifting power structure 13. When the lifting power structure 13 outputs a vertical force to lift the lifting plate 15, thereby adjusting the height of the dummy vehicle body 3 in the vertical direction, the length direction of the guide sleeve 17 is parallel to the vertical direction.

[0031] One end of the guide post 16 is connected to one side of the lifting plate 15 (the lower surface of the lifting plate 15), and the other end of the guide post 16 is located inside the guide sleeve 17, which is fixed to the frame 6, as shown below. Figure 5As shown, the guide sleeve 17 is fixed inside the frame 6. Therefore, when the lifting power structure 13 outputs a vertical force to lift the lifting plate 15, thereby adjusting the height of the dummy vehicle body 3 in the vertical direction, the guide sleeve 17 and the guide column 16 limit the output force of the lifting power structure 13 and the movement direction of the lifting plate 15, thus ensuring the stability of the lifting power structure 13 in the process of lifting the lifting plate 15 and avoiding deviation in the lifting direction.

[0032] Preferably, in order to prevent the dummy trolley 2 from falling accidentally and causing the wheels to touch the ground and causing danger, a buffer is laid on the side of the lifting plate 15 that is used to abut the dummy trolley 2, such as: a 45mm thick nylon block is placed between the lifting plate 15 and the dummy trolley 2.

[0033] Preferably, the lifting power structure 13 can be configured as a telescopic structure. For example, the lifting power structure 13 can be configured as a cylinder or hydraulic cylinder 14 with a vertically arranged piston, which is connected to one side of the lifting plate 15 (the lower surface of the lifting plate 15).

[0034] Through the above scheme, when the rail-crossing transfer machine 1 carries the car body 3, the rail-crossing transfer machine 1 outputs vertical force through the lifting power structure 13 to lift the lifting plate 15, thereby lifting the dummy trolley 2. Then, the dummy trolley 2 can be lifted away from the platform, thus avoiding collision between the dummy trolley 2 and the platform. Then, the rail-crossing transfer machine 1 can move its position through the car-machine moving device 10, thereby carrying the dummy trolley 2 to move its position. This achieves rapid movement and track changing of the car body 3 without significantly changing the factory structure, without affecting personnel passage and operation, ensuring smooth logistics in the workshop, reducing project costs, and compared with the previous method of using overhead cranes, it does not require the installation of lifting equipment each time, greatly reducing the labor intensity of workers and improving production efficiency.

[0035] Furthermore, based on any of the above embodiments, the following configuration is made for the merchant's vehicle-mounted mobile device 10: the vehicle-mounted mobile device 10 includes: a wheel set, a mobile power structure 18, and a transmission structure 19, wherein the wheel set is adapted to the aforementioned connecting track 5. Moreover, the transmission structure 19 is connected between the power output end of the mobile power structure 18 and the wheel set, for transmitting the power output by the mobile power structure 18 to the wheel set to drive the wheel set to rotate, thereby realizing the movement of the vehicle-mounted mobile device 1. The mobile power structure 18 can be exemplaryly configured as an electronic control system, such as a servo motor powered by a battery 12; the transmission structure 19 can be exemplaryly configured as a chain drive.

[0036] Through the above scheme, when the rail-crossing transfer machine 1 carries the car body 3, the rail-crossing transfer machine 1 outputs vertical force through the lifting power structure 13 to lift the lifting plate 15, thereby lifting the dummy trolley 2. Then, the dummy trolley 2 can be lifted away from the platform, thus avoiding a collision between the dummy trolley 2 and the platform. Then, the moving power structure 18 outputs power, which drives the wheel set to rotate through the transmission structure 19, thereby enabling the rail-crossing transfer machine 1 to move its position on the connecting rail 5, and then move the dummy trolley 2 to its position. This achieves rapid movement and rail changing of the car body 3 without significantly altering the factory structure, without affecting personnel passage and operations, ensuring smooth logistics in the workshop, reducing project costs, and compared with the previous method of using overhead cranes, it does not require the installation of lifting equipment each time, greatly reducing the labor intensity of workers and improving production efficiency.

[0037] according to Figure 6-7 As shown, in addition to any of the above embodiments, the above-mentioned track-crossing vehicle transfer machine 1 also includes an alignment component, which is disposed on the side of the frame 6 and is used to align and calibrate the movement of the plurality of track-crossing vehicle transfer machines 1.

[0038] Specifically, when at least two of these rail-mounted vehicle transfer machines 1 are used to move a vehicle body 3, the number of connecting tracks 5 corresponds one-to-one with the wheel sets of the rail-mounted vehicle transfer machine 1, and each wheel set of the rail-mounted vehicle transfer machine 1 is adapted to the corresponding connecting track 5. Furthermore, according to... Figure 6 As shown, alignment components are arranged on the opposite sides of adjacent rail-crossing vehicles 1 to ensure high-precision synchronous movement between at least two rail-crossing vehicles 1.

[0039] Specifically, the alignment components mentioned above can preferably be configured as a target and a laser pointer. Therefore, when at least two track-crossing vehicles 1 require high-precision synchronous movement (e.g., the error between adjacent track-crossing vehicles 1 is controlled to not exceed 50mm), to further ensure safety and allow the operator to visually observe whether the synchronization error exceeds the limit, a sticker is affixed to the side of the right track-crossing vehicle 1. Figure 7 The target shown has a corresponding laser pointer installed on the side of the left-hand track-moving machine 1. When at least two track-moving machines 1 move, the red dot of the laser pointer is projected onto the target of the right-hand track-moving machine 1. The synchronization error value can be observed through the engraving lines, and the operator can decide whether it is safe based on this.

[0040] Second embodiment: according to Figure 1-7 As shown, the second embodiment discloses a train assembly platform, which can also be configured as a train assembly workshop, belonging to a train assembly line using an assembly line. The train assembly platform includes: a platform, a dummy trolley 2, an assembly track 4, a transfer track 41, a connecting track 5, and a track-crossing car transfer machine 1.

[0041] The platform can be either ground-based or a workbench; this embodiment does not impose any limitations, as long as it meets the requirements of this embodiment.

[0042] In addition, the dummy trolley 2 is used to carry the car body 3, which can be any rail vehicle such as a locomotive, EMU, high-speed rail, or maglev train. The number of assembly tracks 4 is set to at least two. All assembly tracks 4 are laid on the platform, and each assembly track 4 is adapted to the dummy trolley 2. The transfer track 41 is laid on the platform and located between adjacent assembly tracks 4. The transfer track 41 is adapted to the dummy trolley 2. The connecting track 5 is also laid on the platform, and the connecting track 5 connects the transfer lane 41 and the assembly track 4; while the rail-crossing vehicle transfer machine 1 is adapted to the connecting track 5.

[0043] Furthermore, the track-crossing transfer machine 1 is located below the dummy trolley 2 and is used to lift the dummy trolley 2 to adjust its vertical position. That is, the track-crossing transfer machine 1 lifts the dummy trolley 2 to adjust its vertical position. Thus, through the cooperation of the track-crossing transfer machine 1 and the connecting track 5, after the track-crossing transfer machine 1 lifts the dummy trolley 2 so that it leaves the platform, the track-crossing transfer machine 1 travels on the connecting track 5, thereby moving the dummy trolley 2 from the transfer lane 41 to the assembly track 4 or from the assembly track 4 to the transfer lane 41. Then, the height of the dummy trolley 2 is lowered so that it lands on the target track, thereby realizing the movement of the car body 3 between the transfer track 41 and the assembly track 4 for track changing.

[0044] Based on the above, the following preferred option can be made: the assembly track 4 and the transfer track 41 are arranged in parallel.

[0045] It is worth noting that in this embodiment, the platform may be provided with only a connecting track 5 and at least two assembly tracks 4. The at least two assembly tracks 4 are arranged in parallel. Moreover, the connecting track 5 connects adjacent assembly tracks 4. Through the cooperation of the track-crossing vehicle transfer machine 1 and the connecting track 5, the vehicle body 3 can be moved between the assembly tracks 4 to change tracks.

[0046] Through the above solution, by connecting track 5 and the track-shifting machine 1, the car body 3 can be quickly moved and the track changed without significantly altering the factory structure. This does not affect personnel passage or operations, ensures smooth logistics in the workshop, reduces project costs, and compared to the previous method of using overhead cranes, it eliminates the need to install lifting equipment each time, greatly reducing the labor intensity of workers and improving production efficiency.

[0047] Furthermore, when at least two of the rail-crossing transfer machines 1 are configured to move a single car body 3, the number of connecting tracks 5 corresponds one-to-one with the number of rail-crossing transfer machines 1, and each rail-crossing transfer machine 1 is adapted to a corresponding connecting track 5. Moreover, according to... Figure 6 As shown, alignment components are respectively arranged on the opposite sides of the adjacent track-crossing vehicle transfer machine 1.

[0048] Specifically, the alignment components mentioned above can preferably be configured as a target and a laser pointer. Therefore, when at least two track-crossing vehicles 1 require high-precision synchronous movement (e.g., the error between adjacent track-crossing vehicles 1 is controlled to not exceed 50mm), to further ensure safety and allow the operator to visually observe whether the synchronization error exceeds the limit, a sticker is affixed to the side of the right track-crossing vehicle 1. Figure 7 The target shown has a corresponding laser pointer installed on the side of the left-hand track-moving machine 1. When at least two track-moving machines 1 move, the red dot of the laser pointer is projected onto the target of the right-hand track-moving machine 1. The synchronization error value can be observed through the engraving lines, and the operator can decide whether it is safe based on this.

[0049] It is worth noting that when alignment components are arranged on the opposite sides of adjacent rail-crossing vehicles 1 to ensure high-precision synchronous movement between at least two rail-crossing vehicles 1, high-precision control of the movement of at least two rail-crossing vehicles 1 is also required. Therefore, in another embodiment, the above-mentioned EMU assembly platform further includes: a fusion controller, which is connected to the lifting device 9 and / or the vehicle-machine moving device 10 of the at least two rail-crossing vehicles 1, and is used to control the operating state of the lifting device 9 and / or the vehicle-machine moving device 10. Thus, by fusion of the controllers of at least two rail-crossing vehicles 1, the fusion controller can achieve high-precision synchronous control of at least two rail-crossing vehicles 1.

[0050] Of course, the fusion controller can be set outside the rail-crossing vehicle transfer machine 1; or it can be set on any rail-crossing vehicle transfer machine 1. For example, each rail-crossing vehicle transfer machine 1 is equipped with a controller. When high-precision synchronous control of at least two rail-crossing vehicle transfer machines 1 is required, the controller of any rail-crossing vehicle transfer machine 1 can be set as the fusion controller to control the at least two rail-crossing vehicle transfer machines 1.

[0051] The specific terminology and implementation principles of the EMU assembly platform in this embodiment can be found in the relevant settings of a track-crossing vehicle transfer machine 1 in any embodiment of the present invention, and will not be repeated here.

[0052] Third embodiment: In order to enable the transfer and relocation of the car body 3 between at least two transfer tracks 41, or between at least two assembly tracks 4, or between transfer tracks 41 and assembly tracks 4 in the EMU assembly workshop (i.e., the aforementioned EMU assembly platform) using an assembly line, this embodiment provides a track-crossing car transfer machine 1, which has the characteristics of convenient operation and rapid track relocation.

[0053] Specifically, the rail-crossing vehicle transfer machine 1 mainly comprises: a frame 6, wheel sets, a driving wheel axle assembly 7, a driven wheel axle assembly 8, a vehicle moving device 10, a lifting device 9, a protective cover 11, a battery pack 12, an electrical control system, and a hydraulic system 13.

[0054] Existing EMU assembly workshops typically have three parallel tracks: the middle track is the transfer track 41, and the two side tracks are the assembly tracks 4. Eight assembly stations are arranged sequentially along the two side assembly tracks 4.

[0055] The existing EMU assembly workshop is modified by laying two connecting tracks 5 to connect the transfer track 41 and the assembly track 4. Moreover, the connecting track 5 is perpendicular to the connecting transfer track 41 and the assembly track 4. The wheel set of the track-crossing machine 1 is adapted to the connecting track 5 so that the track-crossing machine 1 can run back and forth on the connecting track 5.

[0056] The rail-crossing transfer machine 1 is characterized by its low height and narrow width, allowing it to enter under the dummy trolley 2 supporting the car body 3. The lifting device 9 of the rail-crossing transfer machine 1 lifts the dummy trolley 2, making the track wheels of the dummy trolley 2 completely higher than the platform. Then, the two rail-crossing transfer machines 1 drive the dummy trolley 2 and the car body 3 to move laterally to the assembly rails 4 on both sides. After that, the lifting device 9 is lowered, and the track wheels of the dummy trolley 2 fall onto the transfer rail 41, completing the track-changing process of the car body 3. Of course, the dummy trolley 2 can also be moved from the transfer rail 41 to the assembly rail 4 in the same way.

[0057] The rail-crossing vehicle transfer machine 1 is powered by a storage battery 12 and is driven by a chain drive, a servo motor, and remote control.

[0058] The lifting device 9 of the rail-crossing vehicle transfer machine 1 uses a single hydraulic cylinder 14 for lifting, and the lifting plate 15 is guided by guide columns 16 and guide sleeves 17 between it and the frame 6 to ensure that the lifting plate 15 moves vertically up and down on the ground.

[0059] The beneficial effects of this utility model are that, through the above solutions, the vehicle body 3 can be quickly changed without significantly altering the factory structure, without affecting personnel passage and operations, ensuring smooth logistics in the workshop, reducing project costs, and compared with the previous method of using overhead cranes for transportation, there is no need to install lifting equipment each time, which greatly reduces the labor intensity of workers and improves production efficiency.

[0060] Specifically, such as Figure 1As shown: the dummy trolley 2 supports the car body 3 to move on the middle track B (i.e. the transfer track 41 mentioned above). The car body 3 needs to be moved from the middle track B (i.e. the transfer track 41 mentioned above) to the two sides A track A (i.e. the transfer track 41 mentioned above) and / or C track (i.e. the transfer track 41 mentioned above).

[0061] like Figure 2 As shown, the two track-crossing transfer machines 1 move synchronously to the dummy trolley 2. The two track-crossing transfer machines 1 use the lifting device 9 to lift the dummy trolley 2 and the car body 3 synchronously. Then, the two track-crossing transfer machines 1 move synchronously to the assembly track 4. The lifting device 9 is lowered, and the track-crossing transfer machine 1 moves out from under the dummy trolley 2, completing the entire track-changing process of the car body 3.

[0062] like Figure 3 and Figure 4 As shown, the rail-crossing vehicle transfer machine 1 mainly comprises a frame 6, wheel sets, a drive axle assembly 7 that engages with the wheel sets, a driven axle assembly 8 that engages with the wheel sets, a lifting device 9, a vehicle-machine moving device 10, a protective cover 11, a battery 12, a hydraulic system 13, and an electronic control system. The lifting device 9 can vertically lift the dummy trolley 2 by 70mm to ensure the wheel flanges are above the ground, thus not obstructing the movement of the rail-crossing vehicle transfer machine 1 along the connecting track 5. Furthermore, after the lifting device 9 lifts the dummy trolley 2, a 45mm thick nylon block (i.e., the aforementioned buffer) is placed between the frame 6 and the dummy trolley 2 to prevent the dummy trolley 2 from accidentally falling and causing the wheels to touch the ground, thus preventing potential hazards.

[0063] like Figure 5 As shown, two guide sleeves 17 are mounted on the frame 6, the lifting plate 15 is fixed together with the guide column 16, and the hydraulic cylinder 14 drives the lifting plate 15 to move up and down along the guide sleeves 17 via the lifting power structure 13. The lifting power structure 13, the hydraulic cylinder 14, the lifting plate 15, the guide column 16 and the guide sleeves 17 together constitute the lifting device 9.

[0064] like Figure 5 As shown, the left axle is the driving axle assembly 7, and the right axle is the driven axle assembly 8. The small sprocket 21 is connected to the output shaft of the servo motor reducer, and the large sprocket 20 is connected to the driving axle assembly 7. The power output by the servo motor is transmitted to the driving axle assembly 7 through the chain drive (i.e. the transmission structure 19 mentioned above), thereby realizing the forward and backward movement of the track-crossing vehicle 1.

[0065] like Figure 6 and Figure 7 As shown, the two track-crossing moving machines 1 need to move synchronously, with the error controlled within 50mm. To further ensure safety and allow the operator to visually see whether the synchronization error exceeds the limit, the specific procedure is as follows: A sticker is affixed to the side of the right track-crossing moving machine 1... Figure 7The target shown has a laser pointer installed on the side of the track-crossing vehicle 1 on the left. When moving, the red dot of the laser pointer is projected onto the target of the track-crossing vehicle 1 on the right. The synchronization error value can be observed through the engraved lines, and the operator can decide whether it is safe based on this.
