Description

Technical Field

[0001] This utility model relates to the field of railway maintenance equipment technology, and more specifically, to a bogie moving device. Background Technology

[0002] A railway freight car consists of a car body and bogies mounted beneath the car body, serving as the running gear. During assembly, painting, and maintenance processes, bogies are used to move the car body between stages. In processes such as welding and painting, the car body needs to be raised to separate it from the bogies, and then the bogies are pushed out from under the car body before proceeding to the next step. After the process is completed, the bogies are pushed back under the car body, and the car body is lowered to reconnect with the bogies. Therefore, the movement of the bogies is crucial for improving production efficiency and process quality.

[0003] In related technologies, bogie movement relies on manual operation, a method with significant limitations in practical applications. Firstly, manual bogie movement not only increases the workload of operators, leading to high labor intensity, but also poses significant safety hazards due to the confined space beneath the car body. Furthermore, manual bogie movement makes it difficult to precisely control the displacement during both extension and retraction, resulting in the bogie failing to accurately return to its initial position beneath the car body. This necessitates repeated adjustments to the bogie's position, reducing work efficiency.

[0004] Therefore, the use of manual operation to move the bogie in related technologies results in low work efficiency. Utility Model Content

[0009] Furthermore, the bogie moving device also includes a second guide rail, a first slider, a second slider, and a threaded rod disposed on the lifting platform. A first gripper is disposed on the first slider, which has a first threaded hole. The first slider is guided and engaged with the second guide rail. A second gripper is disposed on the second slider, which has a second threaded hole. The second slider is guided and engaged with the second guide rail. A second driving member drives the threaded rod to rotate. The threaded rod has a first threaded segment and a second threaded segment with opposite thread directions.

[0010] Furthermore, the first driving component includes a drive motor, a gear, and a rack meshing with the gear. The drive motor is mounted on the base, the gear is mounted on the motor shaft of the drive motor, and the rack is mounted on one side of the first guide rail.

[0011] Furthermore, the bogie moving device also includes a controller, and the drive motor is a servo motor. The servo motor includes a motor body and an encoder. Gears are set on the motor shaft of the motor body. The encoder is used to detect the rotation angle of the motor shaft of the motor body. The encoder is connected to the controller via signal, and the controller is connected to the motor body via control.

[0012] Furthermore, the bogie moving device also includes a lifting guide component, which is disposed between the base and the lifting platform, and the lifting guide component is guided and engaged with the lifting platform; the lifting guide component includes a guide sleeve and a guide rod, the guide rod is movably disposed inside the guide sleeve along the axial direction of the guide sleeve to guide and engage with the guide sleeve, one of the guide sleeve and the guide rod is disposed on the base, and the other of the guide sleeve and the guide rod is disposed on the lifting platform; and / or, there are two lifting guide components, and the two lifting guide components are respectively disposed on both sides of the telescopic component.

[0013] Furthermore, with the horizontal plane as the projection plane, the projection of the lifting platform is entirely within the projection of the base; or, with the horizontal plane as the projection plane, the projection of the lifting platform is at least partially outside the projection of the base, and the projection of the pivot assembly is outside the projection of the base.

[0014] Furthermore, the bogie moving device also includes a third slider disposed on the base, the third slider being guided and engaged with the first guide rail; and / or, the bogie moving device also includes a roller rotatably disposed on the first gripper, the roller protruding from the surface of the first gripper facing the second gripper.

[0016] The bogie moving device, utilizing the technical solution of this utility model, is used to move the bogie.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use.

[0031] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0033] like Figures 1 to 4As shown, in this embodiment, the bogie moving device is used to move the bogie. The bogie moving device includes: a first guide rail 10, a base 20, a first drive member 30, a lifting platform 40, a telescopic member 50, a shaft clamping assembly 60, and a position detection member 70. The base 20 is movably mounted on the first guide rail 10. The first drive member 30 is used to drive the base 20 to move. The lifting platform 40 is movably mounted on the base 20. The first end of the telescopic member 50 is connected to the base 20, and the second end of the telescopic member 50 is connected to the lifting platform 40. The shaft clamping assembly 60 includes a first gripper 61 and a second gripper 62 movably mounted on the lifting platform 40. The shaft clamping assembly 60 has a clamping state in which the first gripper 61 and the second gripper 62 are brought closer together, and a releasing state in which the first gripper 61 and the second gripper 62 are moved away from each other. The position detection member 70 is mounted on the lifting platform 40 and is used to detect the position of the axle 200 of the bogie.

[0034] Thus, the base 20 is driven to move on the first guide rail 10 by the first driving component 30, enabling the base 20 to move the lifting platform 40 and the axle clamping assembly 60 in translation. The position detection component 70 detects the position of the bogie axle 200, accurately determining the distance the base 20 needs to move in translation, allowing the lifting platform 40 and the axle clamping assembly 60 to move more precisely below the axle 200, and also allowing the axle clamping assembly 60 to rise more precisely to the axle 200. The telescopic component 50 allows the lifting platform 40 to rise and fall, enabling the first gripper 61 and the second gripper 62 mounted on the lifting platform 40 to move to the axle 200, and switching the axle clamping assembly 60 to the clamping state to clamp the axle 200. In this way, the connection between the axle-holding assembly 60 and the axle 200 allows the bogie moving device to connect with the axle 200. The first driving member 30 drives the base 20 to move, enabling the bogie moving device to move the bogie, allowing it to be pushed out or pushed in from under the car body. Furthermore, the position detection member 70 allows the bogie moving device to accurately identify the position of the axle 200, and the first driving member 30 accurately controls the moving distance of the bogie moving device, ensuring the bogie is accurately pushed back to its initial position under the car body, thus improving work efficiency. Therefore, the technical solution of this application effectively solves the problem of low work efficiency caused by manual operation of bogie movement in related technologies.

[0035] Furthermore, the position detection component 70 is mounted on the lifting platform 40, allowing it to rise and fall together with the axle clamping assembly 60. This enables the position detection component 70 to more accurately detect the position of the axle 200, improving detection accuracy. The first gripper 61 and the second gripper 62, by approaching each other, clamp the axle 200 of the bogie. This allows the axle clamping assembly 60 to move the base 20 in different directions, enabling the bogie moving device to push and push the bogie in, thus achieving two-way transmission of the bogie. Compared to pushing the axle 200 from only one side, clamping the axle 200 with the first gripper 61 and the second gripper 62 improves the positional accuracy of the bogie moving device during axle 200 movement and reduces the likelihood of the bogie continuing to move due to inertia.

[0036] like Figures 1 to 4 As shown, the bogie moving device also includes a second drive unit 80 mounted on the lifting platform 40. The second drive unit 80 is used to drive the first gripper 61 and the second gripper 62 to move closer to or further apart from each other. By mounting the second drive unit 80 on the lifting platform 40, precise control of automatic clamping and release of the first gripper 61 and the second gripper 62 is achieved, enhancing the flexibility of the axle clamping assembly 60 and the accuracy of clamping the axle 200, thereby improving work efficiency.

[0037] like Figures 1 to 4 As shown, the bogie moving device also includes a controller. A position detection element 70 is signal-connected to the controller, which is also connected to the first drive element 30, the second drive element 80, and the telescopic element 50. Thus, the position detection element 70 detects the position of the bogie axle 200 and sends the detected position signal to the controller. The controller can control the first drive element 30, the second drive element 80, and the telescopic element 50 to control the translation of the base 20, the lifting platform 40 to rise and fall, and the axle clamping assembly 60 to clamp or release the axle 200, reducing manual intervention and improving work efficiency. The controller integrates the position detection element 70, the first drive element 30, the second drive element 80, and the telescopic element 50, improving the automation and accuracy of the operation. Furthermore, the controller facilitates the automated integration of the bogie moving device with other processes, increasing automation, reducing safety hazards caused by manual operation, shortening auxiliary time, and improving production efficiency.

[0038] In this embodiment, the position detection element 70 is a laser rangefinder sensor. The position detection element 70 is disposed below the axle assembly 60. The position detection element 70 can detect the horizontal and vertical positions of the bogie axle 200, facilitating control of the horizontal movement distance of the base 20 and the vertical lifting distance of the lifting platform 40. By detecting the position of the surface of the bogie axle 200 closest to the position detection element 70, and using the known radius of the axle 200, the position detection element 70 can calculate the horizontal and vertical positions of the axle 200's axis. The telescopic element 50 is a telescopic servo electric cylinder. The telescopic element 50 has a lowering position that lowers the lifting platform 40 to a position below the axle 200 and an upward position that raises the lifting platform 40 to approach the axle 200.

[0039] like Figures 1 to 4 As shown, the bogie moving device also includes a second guide rail 41, a first slider 42, a second slider 43, and a threaded rod 44, all mounted on the lifting platform 40. A first gripper 61 is mounted on the first slider 42, which has a first threaded hole and is guided to engage with the second guide rail 41. A second gripper 62 is mounted on the second slider 43, which has a second threaded hole and is guided to engage with the second guide rail 41. A second driving member 80 drives the threaded rod 44 to rotate. The threaded rod 44 has a first threaded segment and a second threaded segment with opposite thread directions. The first threaded hole engages with the first threaded segment, and the second threaded hole engages with the second threaded segment. Thus, by driving the threaded rod 44 to rotate via the second driving member 80, the first slider 42 and the second slider 43 can move in opposite directions, facilitating the switching of the bearing assembly 60 between a clamping state and a releasing state. Furthermore, the cooperation between the first slider 42 and the second guide rail 41, and the cooperation between the second slider 43 and the second guide rail, makes the movement of the first slider 42 and the second slider 43 more stable and reliable. The design of the first threaded section and the second threaded section with opposite rotation directions allows the first gripper 61 and the second gripper 62 to move closer to or further away from each other, optimizing the working efficiency of the shaft clamping assembly 60.

[0040] like Figures 1 to 4As shown, the first driving component 30 includes a drive motor 31, a gear 32, and a rack 33 meshing with the gear 32. The drive motor 31 is mounted on the base 20, the gear 32 is mounted on the motor shaft of the drive motor 31, and the rack 33 is mounted on one side of the first guide rail 10. The meshing of the gear 32 and the rack 33 effectively converts the rotation of the motor shaft of the drive motor 31 into translational drive, allowing the base 20 to translate along the first guide rail 10. Furthermore, the structure of the gear 32 and rack 33 can transmit a large force, enabling the bogie moving device to move the bogie more smoothly and reliably. Positioning the rack 33 on one side of the first guide rail 10 facilitates its placement and makes the structure of the bogie moving device more compact. The transmission method of the drive motor 31, gear 32, and rack 33 provides a strong and precise power source for the movement of the base 20, improving the response speed and positioning accuracy of the device. This efficient power and transmission mechanism ensures that the base 20 can withstand the weight of the bogie and move smoothly.

[0041] In this embodiment, the first driving component 30 further includes a reducer, the motor shaft of the drive motor 31 drives the reducer to rotate, and the output shaft of the reducer drives the gear 32 to rotate. A mounting plate is provided on the base 20, and the drive motor 31 is mounted on the mounting plate.

[0042] like Figures 1 to 4 As shown, the bogie moving device also includes a controller, and the drive motor 31 is a servo motor. The servo motor includes a motor body and an encoder. Gear 32 is mounted on the motor shaft of the motor body. The encoder is used to detect the rotation angle of the motor shaft of the motor body. The encoder is signal-connected to the controller, and the controller is control-connected to the motor body. The encoder monitors the rotation angle of the motor shaft of the motor body in real time and sends the detected rotation angle signal to the controller, enabling the controller to control the motor body to continue rotating or stop based on the detected rotation angle signal, thereby realizing closed-loop control of the drive motor 31. Furthermore, the encoder can detect the rotation angle of the motor shaft of the motor body, allowing the bogie moving device to determine the bogie extension distance based on the number of rotations of the motor shaft when the bogie is extended. When the bogie returns to its initial position under the car body, it can move the same distance in the opposite direction based on the extension distance, ensuring that the bogie is accurately pushed back to its initial position under the car body. This facilitates the docking operation between the car body and the bogie, avoids repeated adjustments to the bogie position, improves work efficiency, and enhances the automation level of the bogie moving device.

[0043] like Figures 1 to 4As shown, the bogie moving device also includes a lifting guide 90, which is disposed between the base 20 and the lifting platform 40, and the lifting guide 90 guides the lifting platform 40 in a guiding engagement. The lifting guide 90 guides the lifting platform 40 during lifting, improving the smoothness of its movement. The lifting guide 90 includes a guide sleeve and a guide rod. The guide rod is movably disposed within the guide sleeve along its axial direction to guide the lifting platform 40. One of the guide sleeve and guide rod is disposed on the base 20, and the other is disposed on the lifting platform 40. The cooperation of the guide sleeve and guide rod ensures the straightness and stability of the lifting platform 40 during lifting, preventing swaying and deviation during the lifting motion. Furthermore, the guide sleeve and guide rod have a simple structure, facilitating processing and assembly. Two lifting guides 90 are provided, one on each side of the telescopic member 50. This reduces the possibility of the lifting platform 40 deflecting around the axis of the telescopic component 50, making the movement of the bearing assembly 60 more precise.

[0044] In this embodiment, the guide sleeve is disposed on the base 20, and the guide rod is disposed on the lifting platform 40. In some other embodiments, the guide rod is disposed on the base 20, and the guide sleeve is disposed on the lifting platform 40.

[0045] In other embodiments, the bogie moving device further includes a lifting guide 90, which is disposed between the base 20 and the lifting platform 40, and the lifting guide 90 is guided and engaged with the lifting platform 40. The lifting guide 90 includes a guide sleeve and a guide rod, the guide rod being movably disposed within the guide sleeve along the axial direction of the guide sleeve to guide and engage with the guide sleeve, one of the guide sleeve and the guide rod being disposed on the base 20, and the other of the guide sleeve and the guide rod being disposed on the lifting platform 40. Alternatively, there may be two lifting guides 90, with the two lifting guides 90 respectively disposed on both sides of the telescopic member 50.

[0046] like Figures 1 to 3 As shown, with the horizontal plane as the projection plane, the projection of the lifting platform 40 is entirely within the projection of the base 20. This ensures that the center of gravity of the lifting platform 40 falls within the projection of the base 20, allowing the base 20 to more stably move the lifting platform 40.

[0047] like Figure 4As shown, with the horizontal plane as the projection plane, the projection of the lifting platform 40 is at least partially outside the projection of the base 20, and the projection of the axle clamping assembly 60 is also outside the projection of the base 20. This allows for flexible configuration of the axle clamping assembly 60 in different positions, expanding the operating range and adaptability of the bogie moving device. The offset structure, with the projection of the axle clamping assembly 60 outside the projection of the base 20, can effectively address the bogie's transmission needs under narrow or specific workstation conditions. It can be applied to scenarios where the base 20 cannot reach the axle 200 of the bogie due to on-site conditions, facilitating the movement of the axle clamping assembly 60 to the axle 200 and improving the versatility and flexibility of the device.

[0048] like Figures 1 to 4 As shown, the bogie moving device also includes a third slider 21 disposed on the base 20, which is guided and engaged with the first guide rail 10. The guide engagement between the third slider 21 and the first guide rail 10 effectively improves the smoothness and stability of the base 20's movement, reducing vibration during movement. The bogie moving device also includes a roller 611 rotatably disposed on the first gripper 61, protruding from the surface of the first gripper 61 facing the second gripper 62. The rotatable roller 611 on the first gripper 61 reduces the frictional resistance when the axle assembly 60 contacts the bogie axle 200. Through the rolling friction between the roller 611 and the axle 200, the contact area between the axle assembly 60 and the bogie axle 200 is reduced, protecting the bogie axle 200 from damage and extending the bogie's service life.

[0049] In this embodiment, the roller 611 is made of nylon, which further reduces the wear on the axle 200 when the roller 611 comes into contact with the axle 200.

[0050] In other embodiments, the bogie moving device further includes a third slider 21 disposed on the base 20, the third slider 21 being guided and engaged with the first guide rail 10. Alternatively, the bogie moving device further includes a roller 611 rotatably disposed on the first gripper 61, the roller 611 protruding from the surface of the first gripper 61 facing the second gripper 62.

[0051] like Figures 1 to 4 As shown, the bogie moving device also includes a base structure 100 for connection with the ground, and a first guide rail 10 is mounted on the base structure 100. The base structure 100 provides a stable foundation for the first guide rail 10, ensuring the structural stability and long-term operational reliability of the entire bogie moving device.

[0052] In this embodiment, the base structure 100 is made of steel and connected to the ground. It is welded from channel steel, with its lower side fixed to the ground foundation and its upper side equipped with a first guide rail 10 and a rack 33. A receiving recess is provided on the ground, and the bogie moving device is located in the recess. The telescopic member 50 can drive the lifting platform 40 to descend below the ground, and the telescopic member 50 can also drive the lifting platform 40 to rise above the ground so that the axle clamping assembly 60 can move to the axle 200.

[0053] The working principle of this embodiment is as follows: After the vehicle arrives at the workbench, it is positioned using a steel shoe or similar device. A lifting device, such as a car-lifting machine, lifts the car body and simultaneously sends a signal to the bogie moving device. The lifting platform 40 rises from its initial position. The position detection component 70 identifies and records the initial position of the bogie axle 200 and accurately lifts it to the axle 200 position. The axle clamping assembly 60 switches to the clamping state, causing the first clamp 61 and the second clamp 62 to clamp the bogie axle 200. The first drive component 30 drives the base 20 to translate, pushing the bogie to one end of the car body. An encoder records the distance the base 20 moves during this pushing process. The car body is then subjected to flipping, welding, painting, or maintenance operations. After the operation is completed, the car-lifting machine lowers the car body, and simultaneously, the base 20 translates to push the bogie back under the car body. The encoder of the servo motor ensures that the bogie is pushed back to its initial position, ensuring that the upper center plate of the car body can smoothly land on the lower center plate of the bogie. After the car body falls back onto the bogie, the lifting platform 40 descends vertically under the control of the telescopic component 50 to separate the axle assembly 60 from the axle 200.

[0054] The bogie moving device of this embodiment can be applied to railway freight car assembly lines, painting lines, and maintenance lines. It is applicable to 98% of railway freight car models and can realize functions such as automatic bogie ejection, automatic bogie insertion, and rapid insertion to the required position.
