Description

Technical Field

[0001] The present application relates to the field of railway electric train set manufacturing, and in particular to a track moving machine and an EMU assembly platform. Background Art

[0002] The assembly line for EMUs uses a streamlined design. The workshop has three tracks: a central track for transfer and two side tracks for assembly platforms. Eight assembly platforms are arranged sequentially along the tracks. After the car body is transported along the central track from the east end of the workshop to the west end, a 20-ton double overhead crane is used to lift the 10-ton car body to the two sides. However, when the A4 repair process began, the car body's interior and equipment had not been completely removed, and the car body weighed 40 tons. As a result, the 20-ton double overhead crane was unable to lift the 40-ton car body and transfer it to the assembly platform tracks on both sides.

[0003] Replacing an overhead crane with a higher lifting capacity or adding an indoor pit-type trolley platform can solve the car body change problem. However, replacing an overhead crane with a higher lifting capacity requires insufficient load-bearing capacity of the existing overhead crane track and requires simultaneous structural reconstruction of the factory building, which is time-consuming and expensive. Another option is to add a pit-type trolley platform, which requires digging a pit in the workshop. However, having a pit in the workshop affects personnel operations and logistics, hindering production organization. The trolley platform is also expensive and time-consuming to purchase.

[0049] First embodiment:

[0050] according to Figure 1-7 As shown, the first embodiment discloses a track-crossing car moving machine 1, which is arranged under the dummy trolley 2, and the track-crossing car moving machine 1 includes: a frame 6, a lifting device 9 and a car-machine moving device 10, wherein the lifting device 9 is arranged on the frame 6 for adjusting the height of the dummy trolley 2 in the vertical direction; and the car-machine moving device 10 is also arranged on the frame 6 for the track-crossing car moving machine 1 to move its position.

[0051] Among them, the lifting device 9 is used to perform back and forth lifting actions in the vertical direction, and is used to adjust the height of the dummy trolley 2 in the vertical direction, while the vehicle moving device 10 is a moving component, and the track moving machine 1 is adapted to the connecting rail 5 so that the track moving machine 1 can move back and forth on the connecting rail 5.

[0052] Through the above scheme, when the over-track car moving machine 1 carries the car body 3, the over-track car moving machine 1 can lift the dummy trolley 2 through the lifting device 9 to make the dummy trolley 2 away from the platform, thereby avoiding collision between the dummy trolley 2 and the platform, and then the over-track car moving machine 1 can move its position through the car machine moving device 10, thereby carrying the dummy trolley 2 to move its position, so that the car body 3 can be quickly moved to change tracks without significantly changing the factory structure, without affecting the passage and operation of personnel, ensuring smooth logistics in the workshop, reducing project costs, and compared with the previous method of using an overhead crane for lifting, there is no need to install a lifting device each time, which greatly reduces the labor intensity of workers and improves production efficiency.

[0053] Among them, the platform can be the ground or a workbench, which is not limited in this embodiment, as long as it meets the requirements of this embodiment; the dummy trolley 2 is used to carry the car body 3, and the car body 3 can be any rail vehicle such as a locomotive, an EMU, a high-speed railway, a maglev car, etc.; the number of assembly rails 4 is set to at least two, and the assembly rails 4 are all laid on the platform, and each assembly rail 4 is adapted to the dummy trolley 2; the transfer rail 41 is laid on the platform and is located between adjacent assembly rails 4, and the transfer rail 41 is adapted to the dummy trolley 2; the connecting rails 5 are also laid on the platform, and the connecting rails 5 connect the transfer lanes 41 and the assembly rails 4; and the track moving machine 1 is adapted to the connecting rails 5.

[0054] Based on any of the above embodiments, the lifting device 9 can be exemplarily configured as follows:

[0055] The lifting device 9 includes a lifting power structure 13 and a lifting plate 15 .

[0056] 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;

[0057] 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, so as to adjust the height of the dummy trolley 2 in the vertical direction by raising and lowering the height of the position of the dummy trolley 2 back and forth.

[0058] 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 over-track car moving 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 over-track car moving 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 stage when the dummy trolley 2 is lifted, if it is necessary to reduce the distance between the dummy trolley 2 and the platform, the lifting power structure 13 reduces the power output or outputs the lifting force in the opposite direction, so that the lifting plate 15 moves downward until the lifting plate 15 is reset to the adapter hole and the upper surface of the lifting plate 15 is flush with the upper surface of the frame 6.

[0059] Of course, in order to ensure the stability of the lifting power structure 13 during the process of lifting the lifting plate 15 and avoid deviation in the lifting direction, the following settings are made in another embodiment:

[0060] The lifting device 9 also includes: a guide structure, which is arranged between the lifting plate 15 and the lifting power structure 13, and the guide structure is parallel to the power direction of the lifting power output structure, and is used to vertically guide the power output by the lifting power structure 13.

[0061] Specifically, the guide structure includes: a guide sleeve 17 and a guide column 16, the guide column 16 is arranged in the guide sleeve 17 and the guide column 16 can move back and forth along the length direction of the guide sleeve 17, wherein the length direction of the guide sleeve 17 is parallel to the power direction output by the lifting power structure 13, and when the lifting power structure 13 outputs a vertical force to lift the above-mentioned lifting plate 15, thereby adjusting the height of the dummy body 3 in the vertical direction, the length direction of the guide sleeve 17 is parallel to the vertical direction.

[0062] 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 in the guide sleeve 17, and the guide sleeve 17 is fixed to the frame 6, such as: Figure 5 As shown, the guide sleeve 17 is fixed inside the vehicle frame 6. Therefore, when the lifting power structure 13 outputs a vertical force to lift the lifting plate 15, thereby adjusting the vertical height of the dummy vehicle body 3, the guide sleeve 17 and the guide column 16 limit the output force of the lifting power structure 13 and the moving direction of the lifting plate 15, thereby ensuring the stability of the lifting power structure 13 in the process of lifting the lifting plate 15 and preventing deviation in the lifting direction.

[0063] Preferably, in order to prevent the dummy trolley 2 from accidentally falling and causing the wheels to touch the ground and cause 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.

[0064] Preferably, the lifting power structure 13 can be configured as a telescopic structure. For example, the lifting power structure 13 is configured as a cylinder or a hydraulic cylinder 14 and a vertically arranged piston, which is connected to one side of the lifting plate 15 (the lower surface of the lifting plate 15).

[0065] Through the above scheme, when the over-track car moving machine 1 carries the car body 3, the over-track car moving machine 1 outputs vertical force through the lifting power structure 13 to lift the above-mentioned lifting plate 15, thereby lifting the dummy trolley 2, and then the dummy trolley 2 can be lifted to make the dummy trolley 2 away from the platform, thereby avoiding collision between the dummy trolley 2 and the platform, and then the over-track car moving machine 1 can move its position through the car machine moving device 10, thereby carrying the dummy trolley 2 to move its position, realizing the rapid movement and track change of the car body 3 without significantly changing the factory structure, without affecting the passage and operation of personnel, ensuring smooth logistics in the workshop, reducing project costs, and compared with the previous method of using an overhead crane for lifting, there is no need to install a hoist every time, which greatly reduces the labor intensity of workers and improves production efficiency.

[0066] In addition, based on any of the above embodiments, the following settings are 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 above-mentioned 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, and is used to transmit the power output by the mobile power structure 18 to the wheel set, so as to drive the wheel set to rotate and realize the movement position of the track-moving vehicle 1. Among them, the mobile power structure 18 can be exemplarily set as an electronic control system, such as a servo motor, powered by a battery 12; the transmission structure 19 can be exemplarily set as a chain drive.

[0067] Through the above scheme, when the over-track car moving machine 1 carries the car body 3, the over-track car moving machine 1 outputs vertical force through the lifting power structure 13 to lift the above-mentioned lifting plate 15, thereby lifting the dummy trolley 2, and then the dummy trolley 2 can be lifted to make the dummy trolley 2 away from the platform, thereby avoiding collision between the dummy trolley 2 and the platform; then, the mobile power structure 18 outputs power, and drives the wheel group to rotate through the transmission structure 19, so as to realize the over-track car moving machine 1 to move its position on the connecting rail 5, and then carry the dummy trolley 2 to move its position, realizing the rapid movement and track change of the car body 3 without significantly changing the factory structure, without affecting the passage and operation of personnel, ensuring smooth logistics in the workshop, reducing project costs, and compared with the previous method of using an overhead crane for lifting, there is no need to install a sling every time, which greatly reduces the labor intensity of workers and improves production efficiency.

[0068] according to Figure 6-7 As shown, in addition, based on any of the above embodiments, the above-mentioned rail moving machine 1 also includes an alignment component, which is arranged on the side of the frame 6 and is used to align and calibrate the movement of multiple rail moving machines 1.

[0069] Specifically, when at least two of the rail moving machines 1 are set to move a car body 3, the number of connecting rails 5 corresponds to the wheel sets of the rail moving machines 1, and the wheel sets of each rail moving machine 1 are adapted to the corresponding connecting rails 5. Figure 6 As shown, alignment components are respectively arranged on opposite sides of the adjacent track-crossing vehicle moving machines 1 to ensure high-precision synchronous movement between at least two track-crossing vehicle moving machines 1.

[0070] Specifically, for the above alignment components, it can be preferably set as: target and laser pointer. Therefore, when at least two track moving machines 1 need to move synchronously with high precision (for example, the error between adjacent track moving machines 1 is controlled not to exceed 50mm), in order to further ensure safety, the operator can intuitively see whether the synchronization error exceeds the limit, the side of the track moving machine 1 on the right is attached as shown in the figure. Figure 7As shown in the target, a corresponding laser pen is installed on the side of the left track moving machine 1. When at least two track moving machines 1 move, the red dot of the laser pen is projected onto the target of the right track moving machine 1. The synchronization error value can be observed through the engraved lines, and the operator can decide whether it is safe based on this.

[0071] Second embodiment:

[0072] according to Figure 1-7 As shown, the second embodiment discloses an EMU assembly device, which can also be set as an EMU assembly workshop, belonging to an EMU assembly line adopting an assembly line type, wherein the EMU assembly device includes: a platform, a dummy trolley 2, an assembly rail 4, a transfer rail 41, a connecting rail 5 and a track moving machine 1.

[0073] The platform may be the ground or a workbench, which is not limited in this embodiment, as long as it meets the requirements of this embodiment.

[0074] In addition, the dummy trolley 2 is used to carry the vehicle body 3, which can be any rail vehicle such as a locomotive, an EMU, a high-speed train, a maglev train, etc.

[0075] The number of assembly rails 4 is set to at least two, and the assembly rails 4 are all laid on the platform, and each assembly rail 4 is adapted to the dummy trolley 2;

[0076] The transfer track 41 is laid on the platform and is located between adjacent assembly tracks 4 , and the transfer track 41 is adapted to the dummy trolley 2 ;

[0077] The connecting rails 5 are also laid on the platform, and the connecting rails 5 connect the transfer lanes 41 and the assembly rails 4 ; and the rail-crossing vehicle moving machine 1 is adapted to the connecting rails 5 .

[0078] Moreover, the over-track car mover 1 is arranged under the dummy trolley 2, and is used to lift the dummy trolley 2 to adjust the height of the position of the dummy trolley 2 in the vertical direction, that is: the over-track car mover 1 adjusts the height of the dummy trolley 2 in the vertical direction by lifting the dummy trolley 2. Thus, through the cooperation between the over-track car mover 1 and the connecting rail 5, after the over-track car mover 1 lifts the dummy trolley 2 so that the dummy trolley 2 leaves the platform, the over-track car mover 1 travels on the connecting rail 5, thereby moving the dummy trolley 2 from the transfer lane 41 to the assembly rail 4 or moving the dummy trolley 2 from the assembly rail 4 to the transfer lane 41, and then lowering the height of the dummy trolley 2 so that the dummy trolley 2 falls on the target rail, thereby realizing the movement of the car body 3 between the transfer rail 41 and the assembly rail 4 to change tracks.

[0079] On the basis of the above, the following optimization can be made: the assembly track 4 and the transfer track 41 are arranged in parallel.

[0080] It is worth noting that in this embodiment, only a connecting rail 5 and at least two assembly rails 4 can be set on the platform. The at least two assembly rails 4 are set in parallel. Moreover, the connecting rail 5 connects adjacent assembly rails 4. Through the cooperation between the track moving machine 1 and the connecting rail 5, the car body 3 is moved between the assembly rails 4 to change the track.

[0081] Through the above scheme, by connecting the track 5 and the track-crossing car moving machine 1, the car body 3 can be quickly moved and the track can be changed without significantly changing the factory structure, without affecting the passage and operation of personnel, ensuring smooth logistics in the workshop, reducing project costs, and compared with the previous method of using an overhead crane for lifting, there is no need to install the lifting equipment every time, which greatly reduces the labor intensity of workers and improves production efficiency.

[0082] In addition, when the rail moving machine 1 is provided with at least two to move a vehicle body 3, the number of connecting rails 5 corresponds to the number of rail moving machines 1, and each rail moving machine 1 is adapted to the corresponding connecting rail 5. Figure 6 As shown, alignment components are respectively arranged on opposite sides of the adjacent rail moving machines 1.

[0083] Specifically, for the above alignment components, it can be preferably set as: target and laser pointer. Therefore, when at least two track moving machines 1 need to move synchronously with high precision (for example, the error between adjacent track moving machines 1 is controlled not to exceed 50mm), in order to further ensure safety, the operator can intuitively see whether the synchronization error exceeds the limit, the side of the track moving machine 1 on the right is attached as shown in the figure. Figure 7 As shown in the target, a corresponding laser pen is installed on the side of the left track moving machine 1. When at least two track moving machines 1 move, the red dot of the laser pen is projected onto the target of the right track moving machine 1. The synchronization error value can be observed through the engraved lines, and the operator can decide whether it is safe based on this.

[0084] It is worth noting that when alignment components are respectively arranged on the opposite sides of the adjacent track moving machines 1 to ensure high-precision synchronous movement between at least two track moving machines 1, it is also necessary to perform high-precision control on the movement of at least two track moving machines 1. Therefore, in another embodiment, the above-mentioned EMU assembly device also includes: a fusion controller, which is connected to the lifting device 9 and / or the vehicle moving device 10 of the at least two track moving machines 1, and is used to control the operating status of the lifting device 9 and / or the vehicle moving device 10, so as to achieve high-precision synchronous control of at least two track moving machines 1 by the fusion controller of at least two track moving machines 1.

[0085] Of course, the fusion controller can be set outside the track moving machine 1; it can also be set on any track moving machine 1, such as: each track moving machine 1 is provided with a controller, when high-precision synchronous control of at least two track moving machines 1 is required, the controller of any track moving machine 1 can be set as a fusion controller to control the at least two track moving machines 1.

[0086] The nouns and implementation principles involved in the EMU assembly device in this embodiment can be specifically referred to the relevant settings of the track-crossing vehicle moving machine 1 in any embodiment of the present invention, and will not be repeated here.

[0087] Third embodiment:

[0088] In order to realize the transfer and lane change of the car body 3 between at least two transfer rails 41, or at least two assembly rails 4, or between the transfer rail 41 and the assembly rail 4 in the EMU assembly workshop adopting an assembly line-type EMU assembly line (i.e., the above-mentioned EMU assembly device), this embodiment provides a track-crossing car moving machine 1, which has the characteristics of convenient operation and rapid lane change.

[0089] Specifically, the track-crossing vehicle moving machine 1 mainly includes: a frame 6, a wheel set, a driving wheel axle component 7 that cooperates with the wheel set, a driven wheel axle component 8 that cooperates with the wheel set, a vehicle machine moving device 10, a lifting device 9, a protective cover 11, a battery group 12, an electronic control system, a hydraulic system 13, etc.

[0090] Existing EMU assembly workshops are generally equipped with three parallel tracks, the middle track is a transfer track 41, and the two side tracks are assembly tracks 4, and 8 assembly stations are arranged sequentially along the assembly tracks 4 on both sides.

[0091] The existing EMU assembly workshop is renovated and two connecting rails 5 are laid to connect the transfer rail 41 and the assembly rail 4. Moreover, the connecting rails 5 are perpendicular to the transfer rail 41 and the assembly rail 4. The wheel set of the track moving machine 1 is adapted to the connecting rails 5 so that the track moving machine 1 can run back and forth on the connecting rails 5.

[0092] The over-track car moving machine 1 has the characteristics of low height and narrow width, and can enter under the dummy trolley 2 supporting the car body 3. The lifting device 9 of the over-track car moving machine 1 lifts the dummy trolley 2 so that the track wheels of the dummy trolley 2 are completely higher than the platform. Then, the two over-track car moving machines 1 drive the dummy trolley 2 and the car body 3 to move synchronously horizontally to the assembly tracks 4 on both sides, and then drop the lifting device 9. The track wheels of the dummy trolley 2 fall on the transfer track 41, completing the track changing process of the car body 3; of course, the dummy trolley 2 can also be moved from the transfer track 41 to the assembly track 4 in the same way.

[0093] The track moving machine 1 is powered by a battery 12 and is driven by a chain, a servo motor and a remote control.

[0094] The lifting device 9 of the track moving machine 1 adopts a single hydraulic cylinder 14 for jacking, and the lifting plate 15 and the frame 6 are guided by guide pillars 16 and guide sleeves 17 to ensure that the lifting plate 15 moves up and down vertically on the ground.

[0095] The beneficial effect of the present invention is that, through the above schemes, without significantly changing the structure of the factory building, the vehicle body 3 can be quickly changed, without affecting the passage and operation of personnel, ensuring smooth logistics in the workshop, reducing project costs, and compared with the previous method of using an overhead crane for lifting, there is no need to install the lifting equipment every time, which greatly reduces the labor intensity of workers and improves production efficiency.

[0096] Specifically, such as Figure 1 As shown in the figure: the fake trolley 2 supports the vehicle body 3 to move on the middle track B (i.e. the above-mentioned transfer track 41), and the vehicle body 3 needs to be moved from the middle track B (i.e. the above-mentioned transfer track 41) to the A track A (i.e. the above-mentioned transfer track 41) and / or the C track (i.e. the above-mentioned transfer track 41) on both sides.

[0097] like Figure 2 As shown, the two over-track car moving machines 1 move synchronously to under the dummy trolley 2, and the two over-track car moving machines 1 use the lifting device 9 to synchronously lift the dummy trolley 2 and the car body 3, and then the two over-track car moving machines 1 move synchronously to the assembly track 4, the lifting device 9 falls, and the over-track car moving machines 1 move out from under the dummy trolley 2, completing the entire car body 3 lane changing process.

[0098] like Figure 3 and Figure 4 As shown, the track moving machine 1 mainly includes a frame 6, a wheel set, a driving wheel axle component 7 matched with the wheel set, a driven wheel axle component 8 matched with the wheel set, a lifting device 9, a vehicle moving device 10, a shield 11, a battery 12, a hydraulic system 13 and an electronic control system. The lifting device 9 can lift vertically by 70 mm so that the wheel rim of the dummy trolley 2 is higher than the ground and does not hinder the track moving machine 1 from moving along the connecting track 5. In addition, after the lifting device 9 lifts the dummy trolley 2, a 45 mm thick nylon block (i.e., the above-mentioned buffer member) 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 and cause danger.

[0099] like Figure 5 As shown, two guide sleeves 17 are mounted on the vehicle frame 6, the lifting plate 15 is fixed to the guide posts 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 posts 16, and the guide sleeves 17 together constitute the lifting device 9.

[0100] like Figure 5As shown, the left wheel axle is the driving wheel axle component 7, the right wheel axle is the driven wheel axle component 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 wheel axle component 7. The power output by the servo motor is transmitted to the driving wheel axle component 7 through the chain drive (that is, the above-mentioned transmission structure 19), thereby realizing the forward and backward movement of the track moving machine 1.

[0101] like Figure 6 and Figure 7 As shown, the two rail moving machines 1 need to move synchronously, and the error is controlled within more than 50mm. To further ensure safety, the operator can intuitively see whether the synchronization error exceeds the limit. The specific method is: the side of the rail moving machine 1 on the right is attached as shown. Figure 7 As shown in the target, a laser pen is installed on the side of the left track moving machine 1. When moving, the red dot of the laser pen is projected onto the target of the right track moving machine 1. The synchronization error value can be observed through the engraved lines, and the operator can decide whether it is safe based on this.
