Description

Technical Field

[0001] This utility model relates to the field of cargo transfer equipment, and in particular to a platform device and transfer equipment. Background Technology

[0002] In modern logistics systems, various platform devices are widely used for the temporary storage, transfer, and docking of goods. Traditional platform devices typically consist of a fixed platform frame and a working platform, used to support goods and facilitate docking with other equipment.

[0003] Existing platform devices have several technical shortcomings in practical applications. For example, most platform devices adopt a fixed structure, which results in insufficient flexibility when docking with external equipment, making it impossible to accurately adjust the position and often requiring multiple attempts to complete the docking, greatly reducing work efficiency.

[0004] Secondly, traditional platform devices lack effective cargo clamping mechanisms, making it impossible to reliably secure containers of different sizes. This can easily lead to shaking or displacement during transport, affecting cargo safety. Especially during high-speed movement or emergency braking, the lack of reliable self-locking measures to prevent containers from sliding off the platform poses a significant safety hazard.

[0005] Therefore, there is an urgent need to propose a platform device to solve the above problems. Utility Model Content

[0046] The platform device and transfer equipment of this utility model will now be described in more detail with reference to the accompanying drawings, which illustrate preferred embodiments of this utility model. It should be understood that those skilled in the art can modify the utility model described herein while still achieving its advantageous effects. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit the utility model.

[0047] The present invention will be described in more detail below by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0048] like Figure 1 As shown in the figure, this utility model embodiment proposes a convenient and practical platform device, including a platform frame 401, a movable docking platform 403, a clamping device, and a self-locking device 4033.

[0049] Specifically, the clamping devices are located on both sides of the movable docking platform 403 to clamp the cargo box. The self-locking devices 4033 are located on both sides of the movable docking platform 403 and near the ends of the movable docking platform 403 to prevent the cargo box from sliding off the movable docking platform 403.

[0050] In one embodiment, combined with Figures 2-4 As shown, the movable docking platform 403 includes: a platform plate 4031, slide rails 4032, and a working sensor. The slide rails 4032 are connected to both sides of the platform plate 4031, and the platform plate 4031 is slidably mounted on the platform frame 401 via the slide rails 4032. The working sensor is located on the platform plate 4031 and is connected to the slide rails 4032 and the clamping device.

[0051] In one specific example, the slide rail 4032 adopts a high-precision linear guide structure, coupled with ball bearings, enabling the platform plate 4031 to move smoothly and steadily on the platform frame 401, reducing frictional resistance and improving the smoothness and accuracy of sliding. This movable configuration allows the platform to actively adjust its position according to actual needs, enabling precise docking with external equipment, thereby improving docking efficiency and success rate.

[0052] In this embodiment, the working sensors include: a detection sensor 4034, an alignment confirmation sensor 4036, and a docking position sensor 4037. The detection sensor 4034 is disposed on the platform plate 4031 and is used to detect whether there is a cargo box on the platform plate 4031. The alignment confirmation sensor 4036 is disposed at one end of the platform plate 4031 and is used to confirm the alignment status of the platform plate 4031 with the external device. The docking position sensor 4037 is disposed at the other end of the platform plate 4031 and is used to confirm the docking status of the platform plate 4031 with the external device.

[0053] In a specific example, the detection sensor 4034 can be an infrared sensor, a weight sensor, or a photoelectric sensor to monitor the presence status of the cargo box on the platform in real time; the alignment confirmation sensor 4036 and the docking positioning sensor 4037 can be proximity switches, laser rangefinders, or visual recognition systems to provide accurate position information feedback. Those skilled in the art will understand that the type and number of sensors can be set according to actual needs, and other embodiments besides this one are also possible. This multi-sensor collaborative setup enhances the intelligence level of the device and improves the safety and automation of the docking and transfer process.

[0054] In this embodiment, the working sensor further includes a trigger sensor 4035. The trigger sensor 4035 is disposed at one end of the platform plate 4031 and is used to mitigate docking impact during the docking process. In a specific example, the trigger sensor 4035 can be a high-sensitivity proximity switch or force sensor. When it detects the approach of external equipment, it automatically sends a signal to control the platform to decelerate, making the docking process smoother. The addition of the trigger sensor 4035 not only reduces the impact force on goods and equipment during docking and improves the service life of the entire system, but also enhances safety during cargo transportation.

[0055] In one embodiment, the sensors share information and work collaboratively. Specifically, the detection sensor 4034, trigger sensor 4035, alignment confirmation sensor 4036, and docking completion sensor 4037 are connected to the central controller through a signal processing unit to achieve real-time information transmission and processing.

[0056] In one embodiment, such as Figures 5-13 As shown, the clamping device includes a fixed clamping mechanism 402 and a telescopic clamping mechanism 404. Specifically, the fixed clamping mechanism 402 and the telescopic clamping mechanism 404 are arranged opposite to each other for cooperating in clamping the cargo box; the fixed clamping mechanism 402 is used to clamp one side of the cargo box; the telescopic clamping mechanism 404 is used to clamp the other side of the cargo box and is capable of telescopic movement relative to the fixed clamping mechanism 402; the telescopic clamping mechanism 404 includes a telescopic component and a clamping part 4045 connected to each other; the telescopic component is used to drive the clamping part 4045 to telescopically move in the horizontal direction.

[0057] In one specific example, the fixed clamping mechanism 402 and the telescopic clamping mechanism 404 are arranged symmetrically, with one side fixed and the other side movable. This arrangement can adapt to cargo boxes of different widths, enhancing the applicability of the device. The telescopic clamping mechanism 404 can automatically adjust its position according to the width of the cargo box, improving the clamping accuracy and stability.

[0058] In one embodiment, reference continues Figures 5-8 As shown, both the fixed clamping mechanism 402 and the clamping part 4045 include: a fixed frame 4021, a guide block 4022, a clamping plate 4023, and a motion conversion mechanism.

[0059] Specifically, the guide block 4022 is mounted on the fixed frame 4021 and located on both sides of the clamping plate 4023 to limit the movement direction of the clamping plate 4023; the clamping plate 4023 is movably mounted on the fixed frame 4021; the motion conversion mechanism is used to convert the driving force in one direction into the movement of the clamping plate 4023 in a direction perpendicular to that direction.

[0060] In this embodiment, the motion conversion mechanism includes a cam follower 4024 and an electric push rod 4025. Specifically, the fixed end of the electric push rod 4025 is fixed to the fixed frame 4021, and the telescopic end is connected to the cam follower 4024; the clamping plate 4023 is provided with a guide groove 4028; the fixed frame 4021 is provided with a sliding groove; one end of the cam follower 4024 is located in the guide groove 4028, and the other end is located in the sliding groove; the electric push rod 4025 drives the cam follower 4024 to move horizontally, and through the cooperation of the guide groove 4028 and the sliding groove, drives the clamping plate 4023 to move vertically. This motion conversion mechanism utilizes the motion conversion principle of the cam follower 4024 to convert the horizontal thrust generated by the electric push rod 4025 into the vertical movement of the clamping plate 4023, simplifying the control system and improving the structural compactness.

[0061] In this embodiment, the moving direction of the clamping plate 4023 is perpendicular to the fixing frame 4021. The guide blocks 4022 on both sides of the clamping plate 4023 form dovetail grooves with the fixing frame 4021.

[0062] Preferably, the slide groove is horizontally arranged relative to the clamping plate 4023, and the guide groove 4028 is obliquely arranged relative to the slide groove. By setting the horizontal slide groove and the oblique guide groove 4028, the cam follower 4024 can drive the clamping plate 4023 to move vertically along the oblique guide groove 4028 during horizontal movement. Those skilled in the art will know that the inclination angle of the guide groove 4028 can be set according to actual needs, and other embodiments besides this one are also possible. The larger the inclination angle, the greater the vertical movement distance relative to the horizontal movement distance, but the greater the required driving force; the smaller the inclination angle, the smaller the required driving force, but the correspondingly smaller the vertical movement distance. Generally, the inclination angle can be set between 30° and 60° to balance the requirements of driving force and movement distance.

[0063] In this embodiment, both the fixing clamping mechanism 402 and the clamping part 4045 further include: a position detection sensor 4026 and a target recognition sensor 4027. Specifically, the position detection sensor 4026 is mounted on the fixing frame 4021 and is used to detect the position of the clamping plate 4023; the target recognition sensor 4027 is mounted on the fixing frame 4021 and is used to identify the position of the cargo box; both the position detection sensor 4026 and the target recognition sensor 4027 are connected to the telescopic assembly. In a specific example, the position detection sensor 4026 can be a photoelectric switch or a Hall sensor to monitor the position status of the clamping plate 4023 in real time, preventing the clamping plate 4023 from overtravel and causing mechanical damage. The target recognition sensor 4027 can be an infrared sensor or a photoelectric pair to accurately identify the edge position of the cargo box and improve clamping accuracy.

[0064] In a specific example, when the front end of the cargo box is pulled by the telescopic clamping mechanism 404 to a position aligned with the fixed clamping mechanism 402, the fixed clamping mechanism 402 begins to operate. Its electric push rod 4025 activates upon receiving a control signal, extending and pushing the cam follower 4024 to move horizontally. One end of the cam follower 4024 slides in a groove, while the other end moves in an inclined guide groove 4028 on the clamping plate 4023. This combined motion converts the horizontal movement of the cam follower 4024 into a vertical movement of the clamping plate 4023 perpendicular to the fixed frame 4021, causing the clamping plate 4023 to stably move outward and clamp the front end of the cargo box. When the positioning detection sensor 4026 confirms that the clamping is complete, the electric push rod 4025 stops operating, maintaining the clamping state. When it is necessary to release the cargo box, the electric push rod 4025 moves in the opposite direction, causing the cam follower 4024 to return to its original position, the clamping plate 4023 rises, and the clamping of the cargo box is released.

[0065] In one embodiment, reference continues Figures 9-13 As shown, the telescopic assembly includes: a mounting bracket 4041, a fixed rack 4042, a movable rack guide rail 4043, a movable rack 4044, a gear 4046, a drive motor 4047, and a motor guide rail 4048.

[0066] Specifically, the mounting bracket 4041 is mounted on a movable docking platform 403; the motor guide rail 4048 is fixedly mounted on the mounting bracket 4041; the drive motor 4047 is mounted on the motor guide rail 4048 and can slide along the motor guide rail 4048; the fixed rack 4042 and the movable rack guide rail 4043 are both fixedly mounted on the mounting bracket 4041; the movable rack 4044 is mounted on the movable rack guide rail 4043 and can slide along the movable rack guide rail 4043; the gear 4046 is connected to the output shaft of the drive motor 4047 and meshes with the fixed rack 4042 and the movable rack 4044; the clamping part 4045 is fixedly mounted on the movable rack 4044; the movable rack 4044 is arranged parallel to the fixed rack 4042.

[0067] In this embodiment, when the telescopic component is in operation, the drive motor 4047 drives the gear 4046 to rotate. Since the gear 4046 meshes with the fixed rack 4042, the drive motor 4047 moves along the motor guide rail 4048. Simultaneously, the gear 4046 meshes with the movable rack 4044, causing the movable rack 4044 to move along the movable rack guide rail 4043. Through this gear 4046-rack transmission combination, precise telescopic control of the telescopic clamping mechanism 404 is achieved.

[0068] In a preferred embodiment, both the gear 4046 and the movable rack 4044 are positioned at the middle section of the fixed rack 4042, and both the fixed rack 4042 and the movable rack 4044 simultaneously mesh with the same gear 4046. When the drive motor 4047 operates, a multiplication effect is generated because the gear 4046 simultaneously meshes with both the fixed rack 4042 and the movable rack 4044: as the gear 4046 moves along the fixed rack 4042, the movable rack 4044 also moves relative to the gear 4046. This makes the moving distance of the movable rack 4044 twice the moving distance of the gear 4046, thereby achieving a greater range of telescopic movement within a limited space and increasing the working range of the clamping device.

[0069] In another preferred embodiment, the gear 4046 includes a first gear and a second gear. Specifically, the first gear meshes with the fixed rack 4042; the second gear meshes with the movable rack 4044; the first gear and the second gear have different pitch circle diameters. By using gears 4046 with different pitch circle diameters, the speed ratio and displacement ratio of the movable rack 4044 relative to the gears 4046 can be adjusted. For example, when the diameter of the second gear is larger than that of the first gear, the movable rack 4044 will move faster and cover a greater distance; conversely, the movement speed will be slower but the torque will be greater. Those skilled in the art will understand that the diameter ratio of the two gears 4046 can be set according to actual needs, and other embodiments besides this one are also possible.

[0070] In a specific example, when the drive motor 4047 starts, the gear 4046 on its output shaft simultaneously meshes with both the fixed rack 4042 and the movable rack 4044. Since the fixed rack 4042 remains stationary, the rotation of the gear 4046 moves it along the fixed rack 4042, causing the entire motor assembly to slide on the motor guide rail 4048. Simultaneously, the meshing of the gear 4046 with the movable rack 4044 causes the movable rack 4044 to move relative to the movable rack guide rail 4043. This structural design ensures that when the gear 4046 moves one unit distance along the fixed rack 4042, the movable rack 4044 moves two unit distances relative to the mounting bracket 4041, achieving a doubling effect on the travel distance. Because the clamping part 4045 is fixedly mounted on the movable rack 4044, the movement of the movable rack 4044 directly drives the clamping part 4045 to achieve a wide range of high-precision telescopic movements, providing technical assurance for the accurate positioning and clamping of the cargo box.

[0071] In this embodiment, initially, both the fixed clamping mechanism 402 and the telescopic clamping mechanism 404 are in the released state, and the platform is already docked with the target shelf. First, the telescopic clamping mechanism 404, driven by the drive motor 4047, moves the gear 4046 along the fixed rack 4042, and the movable rack 4044 drives the clamping part 4045 to extend towards the cargo box until the target recognition sensor 4027 detects the front end of the cargo box. Then, the electric push rod 4025 of the telescopic clamping mechanism 404 is activated, pushing the cam follower 4024 to move in the slide and guide groove 4028, converting the horizontal motion into the vertical motion of the clamping plate 4023, clamping the front end of the cargo box. Next, the drive motor 4047 runs in the opposite direction, and the movable rack 4044 drives the clamping part 4045 and the clamped cargo box to move towards the center of the platform, while the locking mechanism of the cargo box on the shelf unlocks.

[0072] When the front end of the cargo box aligns with the fixed clamping mechanism 402, the electric push rod 4025 of the fixed clamping mechanism 402 is activated, clamping the other side of the front end of the cargo box. The telescopic clamping mechanism 404 then releases the front clamp. Subsequently, the telescopic clamping mechanism 404 continues to move and adjust its position to the rear end of the cargo box. The electric push rod 4025 again drives the clamping plate 4023 to move and clamp the rear end of the cargo box. At this point, the front end of the cargo box is controlled by the fixed clamping mechanism 402, and the rear end is controlled by the telescopic clamping mechanism 404. Finally, the fixed clamping mechanism 402 releases, and the telescopic clamping mechanism 404 independently controls the cargo box and pulls it to the center of the platform, completing the safe transfer process. This collaborative working mode ensures that the cargo box remains clamped throughout the entire transfer process, greatly improving the stability and safety of the transfer.

[0073] In one embodiment, such as Figures 14-16 As shown, the self-locking device 4033 includes: a self-locking mounting plate 40331, a self-locking guide rod 40332, a self-locking limiting plate 40333, and an elastic element 40335.

[0074] Specifically, the self-locking mounting plate 40331 has a first through channel 40337 and a second through channel 40338 that are connected and perpendicular to each other; the self-locking guide rod 40332 passes through the first through channel 40337 and extends outside the first through channel 40337; the self-locking guide rod 40332 is slidably disposed with the first through channel 40337; the self-locking limiting plate 40333 is slidably disposed in the second through channel 40338; the elastic element 40335 is sleeved on the self-locking guide rod 40332. The self-locking guide rod 40332 is connected to the inner wall of the first through channel 40337. A protrusion 40339 is provided on the self-locking guide rod 40332. A first sliding groove 403311 is provided on the self-locking mounting plate 40331. A second sliding groove 403331 is provided on the self-locking limiting plate 40333. The protrusion 40339 is located within the first sliding groove 403311 and the second sliding groove 403331. The first sliding groove 403311 and the second sliding groove 403331 form a predetermined angle. When the self-locking guide rod 40332 is subjected to external force, the protrusion 40339, guided by the first and second sliding grooves 403311 and 403331, drives the self-locking limiting plate 40333 to move, thereby realizing the automatic locking and unlocking function of the self-locking device 4033 and improving the safety during cargo container transfer.

[0075] Preferably, the first sliding groove 403311 is horizontally arranged, and the second sliding groove 403331 is obliquely arranged relative to the first sliding groove 403311. This structural arrangement, where the first sliding groove 403311 is horizontal and the second sliding groove 403331 is obliquely arranged, allows the horizontal thrust to be converted into vertical movement of the self-locking limiting plate 40333, enhancing the compactness of the structure and its operational reliability.

[0076] Furthermore, this embodiment also includes a self-locking limiting block 40334. Specifically, the self-locking limiting block 40334 is connected to the self-locking limiting plate 40333 on both sides; the self-locking limiting block 40334 moves up and down in the second through channel 40338 under the action of the self-locking limiting plate 40333. The setting of the self-locking limiting block 40334 enhances the limiting effect of the self-locking device 4033 and improves the accuracy and stability of the limiting.

[0077] In this embodiment, the widths of both the self-locking limiting block 40334 and the self-locking limiting plate 40333 are less than or equal to the width of the second through channel 40338. This dimensional fit allows the self-locking limiting block 40334 and the self-locking limiting plate 40333 to move smoothly within the second through channel 40338, improving the response speed and operational reliability of the self-locking device 4033.

[0078] Preferably, the height of the self-locking limiting plate 40333 is greater than the depth of the second through channel 40338. This structural arrangement allows the self-locking limiting plate 40333 to partially extend beyond the second through channel 40338, enhancing the limiting effect on the cargo box and improving the reliability of the limiting mechanism.

[0079] In this embodiment, a buffer block 40336 is connected to one end of the self-locking guide rod 40332. The buffer block 40336 can effectively mitigate the impact force during docking, reduce the risk of damage to the self-locking mechanism and the cargo box, and extend the service life of the equipment.

[0080] In one embodiment, the outer diameter of the buffer block 40336 is larger than the inner diameter of the first through channel 40337. This dimensional fit allows the buffer block 40336 to act as a limiting structure, preventing the self-locking guide rod 40332 from completely exiting the first through channel 40337, thus improving the structural stability and safety of the device.

[0081] Preferably, the first through channel 40337 and the second through channel 40338 together form a cross channel. The cross channel design improves the compactness of the structure and the space utilization, while also providing sufficient movement space for the self-locking guide rod 40332 and the self-locking limiting plate 40333, thereby enhancing the working efficiency of the self-locking device 4033.

[0082] As those skilled in the art will know, the size and material of the self-locking device 4033 can be set according to actual needs, and the self-locking device 4033 also includes other embodiments besides this embodiment. For example, the angle and shape of the first sliding groove 403311 and the second sliding groove 403331 can be adjusted according to specific limiting requirements and space constraints; the elastic element 40335 can be selected from springs or other elastic elements of different materials and elastic coefficients; the buffer block 40336 can be made of different materials such as rubber and silicone to meet different buffering requirements.

[0083] In this embodiment, when the AGV docks with the shelf, the transfer device drives the platform device to move to an appropriate height to contact the shelf. At this time, the end of the self-locking guide rod 40332 (usually the end connected to the buffer block 40336) is pushed by the shelf, and the self-locking guide rod 40332 moves inward along the first through channel 40337. Since the protrusion 40339 on the self-locking guide rod 40332 is located in both the first sliding groove 403311 and the second sliding groove 403331, and the first sliding groove 403311 is horizontally set while the second sliding groove 403331 is obliquely set, when the self-locking guide rod 40332 moves horizontally, the protrusion 40339 generates a vertically downward component force under the constraint of the two sliding grooves, driving the self-locking limiting plate 40333 to move downward along the second through channel 40338. The downward movement of the self-locking limit plate 40333 causes the self-locking limit block 40334 to descend together, thereby releasing the limiting constraint on the cargo box on the platform device, so that the cargo box can be smoothly transferred from the platform to the shelf, or from the shelf to the platform.

[0084] When the external force pushing the self-locking guide rod 40332 disappears, the elastic element 40335 (usually a spring) sleeved on the self-locking guide rod 40332 begins to release elastic energy, pushing the self-locking guide rod 40332 to reset outward. With the reset movement of the self-locking guide rod 40332, the protrusion 40339, under the combined action of the first sliding groove 403311 and the second sliding groove 403331, drives the self-locking limiting plate 40333 to move upward. The upward movement of the self-locking limiting plate 40333 simultaneously causes the self-locking limiting block 40334 to rise to the limiting position.

[0085] Furthermore, this embodiment also proposes a transfer device, including a transfer unit and a platform device as described above; the platform device is disposed on the transfer unit; the transfer unit is used to drive the platform device to move up and down to dock with docking positions at different heights.

[0086] In this embodiment, firstly, the movable docking platform 403 moves precisely on the platform frame 401 via the slide rail 4032, guided in real time by a multi-sensor system, achieving initial docking with external equipment. Secondly, the telescopic clamping mechanism 404, employing a gear-rack transmission principle, extends towards the cargo box under the control of the drive motor 4047, cooperating with the fixed clamping mechanism 402 to form a collaborative clamping system. Then, the motion conversion mechanism converts the horizontal thrust into a vertical clamping force via the cam follower 4024, and the electric push rod 4025 drives the clamping plate 4023 to reliably clamp the cargo box. Finally, the self-locking device 4033 automatically activates the limit function in emergencies to prevent the cargo box from sliding off the platform. The entire device achieves a complete functional chain of high-precision positioning, reliable clamping, and safe transfer. The transfer equipment adjusts the platform height via a lifting mechanism, enabling the platform device to accurately dock with docking positions at different heights, significantly improving the flexibility and adaptability of the device.

[0087] In summary, the platform device and transfer equipment proposed in this utility model have the following advantages:

[0088] By incorporating a movable docking platform and sliding rail structure, the platform plate can slide flexibly on the platform frame, thereby improving the flexibility and accuracy of docking the platform device with external equipment. Simultaneously, the equipped working sensor system can monitor the platform status, cargo position, and docking status in real time, providing timely status feedback and enhancing the automation level of the device. The self-locking device effectively prevents the cargo box from accidentally slipping during transportation, while the clamping devices on both sides improve the stability of the cargo box on the platform, thus enhancing the safety and reliability of the entire system.

[0089] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
