Description

Technical Field

[0001] This utility model relates to an intelligent selection library for center plate pads, specifically, an intelligent selection library for receiving and distributing center plate pads during railway freight car bogie maintenance. Background Technology

[0002] Currently in China, when performing maintenance on railway freight car bogies, the center plate pads need to be stored in a warehouse and then retrieved when needed. During the storage process, workers need to use tools to measure the thickness and test the material of the center plate pads to determine their model. Then, using lifting equipment, the center plate pads are stored in the warehouse. Metal center plate pads are transported using a balance crane, while wooden center plate pads need to be handled by workers. In practice, it has been found that the large quantity and variety of center plate pads result in low storage efficiency. Workers need to perform extensive recording work during measurement and testing, a tedious task prone to errors. Furthermore, the heavy metal center plate pads increase the labor intensity for workers and pose certain safety hazards. Utility Model Content

[0003] The purpose of this utility model is to provide an intelligent selection and matching library for center plate pads, which can perform accurate and reliable automatic loading and unloading operations for center plate pads during railway freight car bogie maintenance, with high efficiency and suitable for widespread application.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A smart selection warehouse for pallet trays includes shelves, an inbound platform, an outbound platform, and a pick-and-place device. The pick-and-place device includes a strip-shaped base arranged in a horizontal direction. A horizontal sliding mechanism is slidably provided on the base. A vertical sliding mechanism is provided on the horizontal sliding mechanism. A telescopic fork is installed on the vertical sliding mechanism. The inbound platform, the shelves, and the outbound platform are arranged on one side of the base. The telescopic fork can move in the horizontal direction under the action of the horizontal sliding mechanism, can rise and fall in the vertical direction under the action of the vertical sliding mechanism, and can extend and retract in a longitudinal direction perpendicular to the horizontal direction in the horizontal plane toward the side of the base where the inbound platform, the shelves, and the outbound platform are located.

[0006] The advantages of this utility model are:

[0007] This utility model is used for the selection and matching of center plate pads during the maintenance of railway freight car bogies. It features a high degree of automation, high work efficiency, reduced number of workers, reduced labor intensity, and high safety. The entry and exit of center plate pads are accurate and reliable. Specifically, when receiving center plate pads, this utility model can detect the thickness and material of the center plate pads and determine the model of the center plate pad according to the thickness and material. This allows center plate pads of the same model to be placed in the same storage space on the shelf, realizing the storage of center plate pads.

[0021] like Figures 1 to 13 As shown, this utility model proposes an intelligent selection warehouse for core trays, including a shelf 10, an inbound platform 20, an outbound platform 40, and a pick-and-place device 30. The pick-and-place device 30 includes a strip-shaped base 310 arranged in the horizontal direction. A horizontal sliding mechanism is slidably provided on the base 310, and a vertical sliding mechanism is provided on the horizontal sliding mechanism. A telescopic fork 37 is installed on the vertical sliding mechanism. The inbound platform 20, the shelf 10, and the outbound platform 40 are arranged on one side of the base 310. The telescopic fork 37 can move in the horizontal direction under the drive of the horizontal sliding mechanism, can rise and fall in the vertical direction under the drive of the vertical sliding mechanism, and can extend and retract in the longitudinal direction perpendicular to the horizontal direction in the horizontal plane toward the side of the base 310 where the inbound platform 20, the shelf 10, and the outbound platform 40 are located.

[0022] like Figure 1 Typically, the shelf 10 is placed between the revenue platform 20 and the expenditure platform 40 and is positioned close to the expenditure platform 40. Furthermore, generally one shelf 10 with a sufficiently large capacity is sufficient. Multiple revenue platforms 20 can be set up side by side, and similarly, multiple expenditure platforms 40 can be set up side by side. Figure 1 The design illustrates a scenario with two revenue platforms 20 and two expenditure platforms 40.

[0023] like Figures 8 to 13 The lateral sliding mechanism includes a pick-and-place lateral slide rail 31, typically two lateral slide rails 31 are arranged in parallel. The lateral slide rails 31 are arranged in the lateral direction on the base 310, and a traveling rack 312 is installed side by side next to the lateral slide rails 31. Figure 8 (Only a portion of the traveling rack 312 is shown). A transverse slider 311 is provided on the transverse slide rail 31 for picking and placing. The transverse slider 311 is fixed to the base plate 32. A traveling gear 391 is installed on the base plate 32. The traveling gear 391 meshes with the traveling rack 312. The traveling gear 391 is connected to the traveling drive motor 381 and rotates under the drive of the traveling drive motor 381. By meshing with the traveling rack 312, it drives the base plate 32 and its vertical sliding mechanism and telescopic fork 37 to move in the transverse direction. Generally, the traveling gear 391 is installed on the output shaft of the traveling drive motor 381. The traveling drive motor 381 can be located on the base plate 32.

[0024] Furthermore, the vertical sliding mechanism includes a lifting column 33 mounted on the base plate 32, with vertical pick-and-place vertical slide rails 34 vertically arranged on the lifting column 33. Typically, two pick-and-place vertical slide rails 34 are arranged in parallel, and lifting racks 342 are installed side by side next to the pick-and-place vertical slide rails 34. Figure 8 (Only a portion of the lifting rack 342 is shown). A vertical slider 341 is slidably mounted on the vertical slide rail 34. The vertical slider 341 is fixed to a vertically arranged connecting plate 35. A lifting gear 392 is mounted on the connecting plate 35. The lifting gear 392 meshes with the lifting rack 342. The lifting gear 392 is connected to the lifting drive motor 382 and rotates under the drive of the lifting drive motor 382. By meshing with the lifting rack 342, it drives the connecting plate 35 and the telescopic fork 37 on it to rise and fall. Generally, the lifting gear 392 is mounted on the output shaft of the lifting drive motor 382. The lifting drive motor 382 can be mounted on the connecting plate 35.

[0025] like Figure 1 and Figure 8 A support rod 36 is installed on the connecting plate 35 along the transverse direction, that is, the length direction of the support rod 36 is consistent with the transverse direction. A telescopic fork 37 is installed on the support rod 36. The telescopic fork 37 performs telescopic movement under the drive of the telescopic drive motor 383, that is, the telescopic fork 37 performs telescopic movement relative to the receiving platform 20, the shelf 10 and the disbursement platform 40 in the longitudinal direction.

[0026] In this utility model, the telescopic fork 37 and the matching telescopic drive motor 383 are existing devices, and their specific structures are not described in detail here.

[0027] In the actual design, two laser rangefinders (not shown in the figure) are installed on the base plate 32, and a reflector (not shown in the figure) is provided at one end of the base 310. One laser rangefinder is set opposite to the reflector in the lateral direction to detect the movement position of the telescopic fork 37 in the lateral direction; the other laser rangefinder is set opposite to the telescopic fork 37 in the vertical direction to detect the lifting position of the telescopic fork 37.

[0028] Of course, in actual design, such as Figure 9 The base 310 should also be provided with limit blocks 39 at both ends (such as limit bolts) to prevent the pick-up and put-down device 30 from detaching from the base 310.

[0029] In actual implementation, the pick-and-place device 30 also includes a control device 50, which is connected to the laser rangefinder, the travel drive motor 381, the lifting drive motor 382, ​​and the telescopic drive motor 383. Based on the ranging signal fed back by the laser rangefinder and the instructions issued by the management system, the control device 50 controls the operation of the travel drive motor 381, the lifting drive motor 382, ​​and the telescopic drive motor 383 to control the movement of the telescopic forks 37 in the lateral, longitudinal, and vertical directions.

[0030] In this utility model, the control device 50 is a well-known electrical control device in the industry, which can be installed on the lifting column 33 of the picking and placing device 30, and is of course not limited.

[0031] In practical applications, preferably, a cable chain groove 60 is provided side by side with the base 310, and a cable chain groove 60 and a cable chain frame 60' are provided on the lifting column 33 of the pick-and-place device 30, but this is not a limitation. The function of the cable chain groove 60 and the cable chain frame 60' is to lay cables and protect them from damage.

[0032] like Figures 2 to 5 The receiving platform 20 includes a rectangular receiving frame 21. The top of the receiving frame 21 has two strip plates 210 forming a receiving support plane. At one end of each strip plate 210, a limiting rod 211 is provided, extending above the receiving support plane. The limiting rod 211 is used to limit the center plate in the longitudinal direction when the worker places it on the receiving support plane. In actual implementation, the worker should ensure the center plate abuts against the limiting rod 211 to align it. Figures 2 to 5 A laser rangefinder 70 and an inductive proximity switch 80 are installed on the limit rod 211. The laser rangefinder 70 is higher than the receiving support plane, and the distance between the laser rangefinder 70 and the receiving support plane is greater than the thickness of the core plate. A horizontal rod 233 is fixed to the top of the receiving frame 21. A receiving transverse slide rail 25 is provided on each end of the horizontal rod 233 extending out of the receiving support plane. Each receiving transverse slide rail 25 is connected to a push rod 26 via a horizontal slider 251. That is, the push rod 26 can slide on the receiving transverse slide rail 25 through the horizontal slider 251. The horizontal rod 233 is connected to a vertical rod 232. A receiving vertical slide rail 27 is vertically provided on the vertical rod 232, which is located below the horizontal rod 233. The vertical slide rail 27 is connected to a connector 28 via a vertical slider 271. That is, the connector 28 can slide on the vertical slide rail 27 via the vertical slider 271. The bottom of the vertical rod 232 is connected to a drive cylinder 22 via a longitudinal rod 231 arranged in the longitudinal direction. The telescopic rod 220 of the drive cylinder 22 extends upward through the longitudinal rod 231 and is connected to the connector 28 via a connecting pin 291. The connector 28 is also connected to the abutting rod 26 via a pull plate member 24. Under the drive of the drive cylinder 22, the connector 28 slides up and down along the vertical slide rail 27 via the vertical slider 271, and then drives the abutting rod 26 to slide along the horizontal slide rail 25 via the horizontal slider 251 through the pull plate member 24.

[0033] In actual production, the frame 21 is welded from square tubing and other profiles. The strip plate 210 is made of steel plate to ensure flatness.

[0034] Furthermore, the two abutment rods 26 move towards or away from each other, and the initial distance between the two abutment rods 26 is greater than the width of the center plate. Here, when the center plate is placed on the receiving support plane, the direction of relative movement of the two abutment rods 26 is defined as the width direction of the center plate, and the distance between the two abutment rods 26 refers to the distance between the two abutment rods 26 in the width direction of the center plate. The width direction of the center plate is consistent with the transverse direction, and correspondingly, the length direction of the center plate is consistent with the longitudinal direction.

[0035] Typically, a laser rangefinder 70 is mounted on the top of each limit rod 211, and an inductive proximity switch 80 is mounted on one of the two limit rods 211. During installation, the laser rangefinder 70 is fixed to the limit rod 211 via an L-shaped mounting bracket 212, and the inductive proximity switch 80 is fixed to the limit rod 211 via an L-shaped mounting bracket 213. Figure 2 .

[0036] In the actual design, the pull plate component 24 includes a first pull plate 241 and a second pull plate 242. One end of the first pull plate 241 is fixedly connected to the push rod 26, and the other end is rotatably connected to one end of the second pull plate 242 via a first pin 243. The other end of the second pull plate 242 is rotatably connected to the connector 28 via a second pin 244.

[0037] like Figure 3 Each push rod 26 is connected to the connector 28 via a pull plate member 24. The two second pull plates 242 form a Y shape with the telescopic rod 220 of the drive cylinder 22.

[0038] In this invention, a laser rangefinder 70 is used to illuminate the strip plate 210 downwards and detect whether a core tray pad is placed on the receiving support surface (the thickness detected when no core tray pad is placed on the receiving support surface is different from the thickness detected when a core tray pad is placed; that is, if the detected thickness changes, it indicates that a core tray pad is placed on the receiving support surface). It also detects the thickness of the core tray pad after the worker places it on the receiving support surface. An inductive proximity switch 80 is used to detect the core tray pad after the worker places it on the receiving support surface. If detected, it indicates that the core tray pad is made of metal; if not detected, it indicates that the core tray pad is made of wood, thus determining the material of the core tray pad. In this field, core tray pads are made of either wood or metal.

[0039] In practical applications, after the worker places the center plate on the receiving support plane (with the center plate abutting against the limit rod 211), the laser rangefinder 70 immediately detects the thickness of the center plate, and the inductive proximity switch 80 immediately detects the material of the center plate. Then, the drive cylinder 22 starts running, and the telescopic rod 220 drives the connecting piece 28 to slide along the receiving vertical slide rail 27. Then, the pull plate component 24 drives the abutting rod 26 to slide along the receiving transverse slide rail 25. The two abutting rods 26 move towards each other from their initial position (at this time, the distance between the two abutting rods 26 is the initial distance, and the two abutting rods 26 are on both sides of the receiving support plane), and together abut against both sides of the center plate, so that the center plate is in the center of the receiving support plane along its own width direction, completing the centering operation. The centering operation facilitates the telescopic fork 37 to accurately and reliably pick up the center plate from the receiving platform 20, so as to accurately pick up the center plate and efficiently put it into storage. Here, after the two push rods 26 push against the center plate and center the center plate, the two push rods 26 return to their initial positions and wait for the next center plate.

[0040] In this utility model, the limiting rod 211, the horizontal rod 233, the vertical rod 232, and the abutting rod 26 can be made of square tubing, and the longitudinal rod 231 can be a U-shaped profile, and of course there are no limitations.

[0041] In this utility model, the connector 28 is as follows Figure 3 , Figure 4 As shown, its structure can vary widely and is not limited. For example... Figure 3 , Figure 4 The connector 28 may include a main body 281, which is used to connect with the second pull plate 242. The main body 281 may be provided with a connecting ear 282, which is used to connect with the telescopic rod 220. In addition, the main body 281 is fixed to the vertical slider 271 by a pin 292.

[0042] In actual implementation, the revenue platform 20 also includes a controller (not shown in the figure), which is connected to the laser rangefinder 70, the inductive proximity switch 80, and the drive cylinder 22. Based on the ranging signal fed back by the laser rangefinder 70, the controller controls the operation of the drive cylinder 22 to perform centering operations on the center plate in the lateral direction.

[0043] In this invention, the controller is a well-known electrical control device in the industry. The laser rangefinder and the inductive proximity switch are existing devices in this field.

[0044] like Figure 6The shelf 10 includes a placement frame 11 welded from tubing. Multiple placement spaces 12 are formed on the placement frame 11. Multiple pairs of support strips 13 are arranged vertically in each placement space 12. The two support strips 13 of each pair of support strips 13 are on the same horizontal plane and are set separately. Each pair of support strips 13 forms a placement plane for placing the pallet pad.

[0045] In practical applications, each placement space 12 is used to place a disc plate of the same model. That is, the disc plates placed in each placement space 12 have the same thickness and material. The model of the disc plate is determined according to its thickness and material.

[0046] In actual manufacturing, the placement frame 11 is assembled from aluminum alloy profiles. The support strip 13 is made of angle aluminum and is used to support the core plate pad.

[0047] like Figure 7 The expenditure platform 40 includes a rectangular expenditure frame 41. The top of the expenditure frame 41 is provided with two strip plates 42 for forming an expenditure support plane. At one end of the two strip plates 42, there is a baffle 43 that is higher than the expenditure support plane. The baffle 43 is used to limit the center plate in the longitudinal direction when the center plate is placed on the expenditure support plane. An L-shaped baffle 44 is provided on the outside of the strip plate 42. The L-shaped baffle 44 is used to limit the center plate in the transverse direction when the center plate is placed on the expenditure support plane.

[0048] In actual production, the support frame 41 is welded from square tubing and other profiles. The strip plate 42 is made of steel plate to ensure flatness. The support platform 40 is used to support the support plate pad, which is removed by the workers.

[0049] like Figure 1 This utility model defines the horizontal, longitudinal and vertical directions. The length direction of the horizontal slide rail 31 of the picking and placing device 30 is defined as the horizontal direction, the direction perpendicular to the horizontal direction in the horizontal plane is the longitudinal direction, and the up and down direction perpendicular to the horizontal plane is the vertical direction.

[0050] The working process of this utility model is as follows:

[0051] The worker places the center plate on the receiving platform 20, abutting it against the limit rod 211. The laser rangefinder 70 then detects the thickness of the center plate, and the inductive proximity switch 80 detects its material. Simultaneously, the cylinder 22 is driven, pressing the center plate against the push rod 26 to center it. The controller of the receiving platform 20 sends the detected center plate thickness and material information to the management system for recording.

[0052] Then, the management system sends instructions to the pick-and-place device 30 based on the thickness and material information of the core plate. The pick-and-place device 30 controls the movement of the telescopic fork 37 in the lateral direction via the walking drive motor 381 and the matching laser rangefinder, and controls the movement of the telescopic fork 37 in the vertical direction via the lifting drive motor 382 and the matching laser rangefinder, so that the telescopic fork 37 is aligned with the core plate on the receiving platform 20. Then, the telescopic drive motor 383 controls the telescopic movement of the telescopic fork 37 to lift and remove the core plate from the receiving platform 20.

[0053] Then, the pick-and-place device 30 also controls the movement of the telescopic fork 37 in the lateral direction through the walking drive motor 381 and the matching laser range sensor, and controls the movement of the telescopic fork 37 in the vertical direction through the lifting drive motor 382 and the matching laser range sensor, so that the telescopic fork 37 is aligned with the placement plane to be used to place the core plate pad, and then controls the telescopic fork 37 to extend and retract through the telescopic drive motor 383 to complete the automatic storage of the core plate pad.

[0054] When a core tray pad needs to be removed from shelf 10, the management system sends a command to the pick-and-place device 30 based on the model information of the core tray pad to be removed. Similarly, the pick-and-place device 30 controls the movement of the telescopic fork 37 in the lateral direction via the travel drive motor 381 and the associated laser rangefinder, and controls the movement of the telescopic fork 37 in the vertical direction via the lifting drive motor 382 and the associated laser rangefinder, so that the telescopic fork 37 is aligned with the placement plane of the core tray pad to be removed, and then controls the extension and retraction movement of the telescopic fork 37 via the telescopic drive motor 383 to lift the core tray pad out.

[0055] Then, the pick-and-place device 30 also controls the movement of the telescopic fork 37 in the lateral direction through the walking drive motor 381 and the matching laser range sensor, and controls the movement of the telescopic fork 37 in the vertical direction through the lifting drive motor 382 and the matching laser range sensor, so that the telescopic fork 37 is aligned with the support plane of the support platform 40. Then, the telescopic drive motor 383 controls the telescopic movement of the telescopic fork 37 to place the core plate on the support plane, completing the automatic removal of the core plate, and waiting for the core plate to be taken away.

[0056] In practice, if the required type of core tray pad is not available on shelf 10, the management system will issue a notification.

[0057] Here, the management system typically includes servers and databases, which will not be detailed here to avoid confusion with the technology.

[0058] The advantages of this utility model are:

[0059] This utility model is used for the selection and matching of center plate pads during the maintenance of railway freight car bogies. It features a high degree of automation, high work efficiency, reduced number of workers, reduced labor intensity, and high safety. The entry and exit of center plate pads are accurate and reliable. Specifically, when receiving center plate pads, this utility model can detect the thickness and material of the center plate pads and determine the model of the center plate pad according to the thickness and material. This allows center plate pads of the same model to be placed in the same storage space on the shelf, realizing the storage of center plate pads. On the other hand, this utility model can retrieve the correct center plate pad from the corresponding storage space on the shelf according to the required model of the center plate pad, realizing the exit of center plate pads.

[0060] The above describes the preferred embodiments of this utility model and the technical principles applied thereto. For those skilled in the art, any obvious changes such as equivalent transformations or simple substitutions based on the technical solutions of this utility model without departing from the spirit and scope of this utility model shall fall within the protection scope of this utility model.
