Description

Technical Field

[0001] This utility model relates to the field of forklift technology, and in particular to a dual-arm robotic intelligent forklift. Background Technology

[0002] The dual-arm robotic forklift is a composite intelligent equipment integrating autonomous navigation, robotic arm operation, and cargo handling functions. It is mainly used in logistics warehousing, intelligent manufacturing, and other scenarios to achieve automated loading, unloading, palletizing, and transportation of goods. The equipment uses the vehicle body as a mobile platform and is equipped with a dual-robotic arm system, a vision recognition module, a motion control unit, and an intelligent interactive terminal. Through multi-sensor fusion and autonomous decision-making algorithms, it achieves precise grasping, handling, and position adjustment of goods.

[0003] Currently, the touch control screen of dual-arm robotic forklifts is usually fixedly installed on the top of the vehicle body, serving as the operation center and status display terminal of the equipment. However, this exposed design faces significant protection deficiencies during equipment transportation: since the touch control screen is directly exposed to the external environment, bumps and collisions during transportation may cause scratches, cracks, or loosening of the internal wiring. Especially during long-distance transportation or when multiple devices are stacked, the screen, lacking physical protection, is extremely vulnerable to damage from external impacts. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose a dual-arm robotic intelligent forklift to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a dual-arm robotic intelligent forklift, including a forklift body. A storage slot is provided on the top of the forklift body. An mounting plate is fixedly installed on the inner wall of the storage slot by bolts. A U-shaped frame is fixedly connected to the top surface of the mounting plate. A hydraulic cylinder is fixedly connected between the U-shaped frame and the mounting plate. The output of the hydraulic cylinder is fixedly connected to a lifting plate through the U-shaped frame. An assembly frame is fixedly connected to one side of the lifting plate. A touch screen is fixedly installed inside the assembly frame by bolts. Two symmetrically arranged frames are fixedly connected to the top surface of the lifting plate. A locking frame is slidably connected between the two frames. A bearing plate is fixedly connected to the top of the locking frame. The bottom surface of the bearing plate is in contact with the top surface of the assembly frame. A camera is fixedly installed on the top surface of the bearing plate by bolts. The camera is electrically connected to the touch screen. A control plate is slidably connected to the inner wall of each frame. A spring is fixedly connected between the control plate and the frame. A locking pin is fixedly connected to the side of the control plate away from the spring. Both locking pins penetrate the frame and engage with the locking frame.

[0007] Preferably, in any of the above solutions, the bottom surface of the support plate is fixedly connected to two symmetrically arranged clamping plates, and the support plate is engaged with the assembly frame through the two clamping plates.

[0008] Preferably, in any of the above solutions, the bottom surface of the lifting plate is fixedly connected to two symmetrically arranged guide rods, the hydraulic cylinder is located between the two guide rods, and both guide rods are slidably connected to the U-shaped frame.

[0009] Preferably, in any of the above solutions, a plurality of linear array support plates are fixedly connected to the side of the assembly frame away from the touch screen, and the bottom ends of the plurality of support plates are fixedly connected to the lifting plate.

[0010] Preferably, in any of the above solutions, the locking frame has snap-fit ​​holes on both the left and right sides, and the two snap-fit ​​pins pass through the frame and snap-fit ​​holes to engage with the locking frame.

[0011] The top surface of the assembly frame is fixedly connected to two symmetrically arranged connecting plates, and the top ends of the two connecting plates are fixedly connected to cover plates, which correspond vertically to the storage slots.

[0012] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0013] 1. Addressing the issue of exposed and vulnerable touchscreen displays in traditional dual-arm robotic forklifts, this device utilizes a storage slot and a lifting assembly frame design to provide a concealed protective space for the touchscreen display. During transport, a hydraulic cylinder drives the lifting platform to descend, retracting the assembly frame along with the touchscreen display into the storage slot on top of the forklift body. At this point, the cover plate and storage slot close, forming a physical protective barrier to prevent the touchscreen display from being directly exposed to the outside environment. This design protects the touchscreen display from bumps, collisions, and dust during transport. For example, when transporting multiple devices stacked together, the structure of the storage slot can withstand the pressure from the devices above, preventing the touchscreen display from shattering due to compression, effectively solving the protective deficiencies of traditional exposed designs.

[0014] 2. The locking frame and snap-fit ​​pin structure design of this equipment ensures the stability and ease of operation of the touch screen display during operation. During operation, the hydraulic cylinder pushes the lifting plate to the predetermined height, and the control panel compresses the spring, causing the snap-fit ​​pin to disengage from the locking frame's snap-fit ​​hole, thus releasing the locking frame and facilitating camera disassembly and maintenance. After operation, sliding the locking frame causes the support plate to press against the assembly frame, and the snap-fit ​​pin automatically engages with the snap-fit ​​hole under the action of the spring, fixing the locking frame between the frames and preventing the touch screen display from shaking due to vibration during equipment operation. Simultaneously, the snap-fit ​​between the snap-fit ​​plate and the assembly frame, and the support plate's support for the lifting plate, further enhance the overall structural stability, ensuring a reliable connection for the touch screen display during forklift movement or robotic arm operation, improving the safety and reliability of human-machine interaction.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto.

[0022] like Figures 1 to 5As shown, a dual-arm robotic intelligent forklift includes a forklift body 1. A storage slot 2 is formed on the top of the forklift body 1. An mounting plate 3 is bolted to the inner wall of the storage slot 2. A U-shaped frame 4 is fixedly connected to the top surface of the mounting plate 3. A hydraulic cylinder 5 is fixedly connected between the U-shaped frame 4 and the mounting plate 3. The output of the hydraulic cylinder 5 passes through the U-shaped frame 4 and is fixedly connected to a lifting plate 6. An assembly frame 7 is fixedly connected to one side of the lifting plate 6. A touch screen display 8 is bolted to the interior of the assembly frame 7. Two symmetrically arranged frames 9 are fixedly connected to the top surface of the lifting plate 6. A locking frame 10 is slidably connected between the two frames 9. A support plate 11 is fixedly connected to the top of the locking frame 10. The bottom surface of the support plate 11 is in contact with the top surface of the assembly frame 7. A camera 12 is fixedly installed on the top surface of the support plate 11 by bolts. The camera 12 is electrically connected to the touch screen 8. A control plate 13 is slidably connected to the inner wall of each frame 9. A spring 14 is fixedly connected between the control plate 13 and the frame 9. A locking pin 15 is fixedly connected to the side of the control plate 13 away from the spring 14. Both locking pins 15 penetrate the frame 9 and lock the locking frame 10.

[0023] As an optional technical solution of this utility model, the bottom surface of the support plate 11 is fixedly connected with two symmetrically arranged clamping plates 16. The support plate 11 is engaged with the assembly frame 7 through the two clamping plates 16. When the support plate 11 covers the top of the assembly frame 7, the clamping plates 16 can be accurately embedded into the corresponding slots of the assembly frame 7 to form a stable mechanical connection, preventing the support plate 11 from shifting due to vibration during forklift operation, ensuring the relative position of the camera 12 and the touch display screen 8 is fixed, and ensuring the accuracy of image acquisition and operation interaction.

[0024] As an optional technical solution of this utility model, the bottom surface of the lifting plate 6 is fixedly connected with two symmetrically arranged guide rods 17, and the hydraulic cylinder 5 is located between the two guide rods 17. Both guide rods 17 are slidably connected to the U-shaped frame 4. When the hydraulic cylinder 5 drives the lifting plate 6 to move up and down, the guide rods 17 slide along the inner wall of the U-shaped frame 4, which can effectively prevent the lifting plate 6 from shifting or shaking to ensure that the touch screen 8 in the assembly frame 7 can be lifted and lowered smoothly.

[0025] As an optional technical solution of this utility model, a number of linear array support plates 18 are fixedly connected to the side of the assembly frame 7 away from the touch screen 8. The bottom ends of the support plates 18 are all fixedly connected to the lifting plate 6. The support plates 18 are distributed in a linear array, which can evenly transfer the external force on the assembly frame 7 to the lifting plate 6 and avoid structural deformation caused by single-point force.

[0026] As an optional technical solution of this utility model, locking frames 10 are provided with locking holes 19 on both the left and right sides. Two locking pins 15 pass through the frame 9 and are locked with the locking frames 10 through the locking holes 19. When the locking frames 10 are slid to the working position, the locking pins 15 are automatically inserted into the locking holes 19 under the elastic force of the spring 14, which firmly fixes the locking frames 10 and prevents them from sliding accidentally during operation.

[0027] As an optional technical solution of this utility model, the top surface of the assembly frame 7 is fixedly connected to two symmetrically arranged connecting plates 20, and the top ends of the two connecting plates 20 are fixedly connected to a cover plate 21. The cover plate 21 corresponds to the storage slot 2 vertically. When the touch screen 8 is put into the storage slot 2, the cover plate 21 is fixedly connected to the assembly frame 7 through the connecting plates 20 to form a closed structure, which effectively prevents dust, water vapor and other pollutants from entering the storage slot 2 and protects the touch screen 8 from external environmental corrosion.

[0028] A dual-arm robotic intelligent forklift operates on the following principle:

[0029] 1) During transportation, the hydraulic cylinder 5 drives the lifting plate 6 to descend, and puts the assembly frame 7 together with the touch screen display 8 into the storage slot 2 on the top of the forklift body 1. At this time, the cover plate 21 closes with the storage slot 2, forming a physical protective barrier.

[0030] 2): During operation, the hydraulic cylinder 5 pushes the lifting plate 6 to rise to the predetermined height, and the control panel 13 compresses the spring 14, so that the locking pin 15 disengages from the locking hole 19 of the locking frame 10, which can release the locking frame 10 and facilitate the disassembly and maintenance of the camera 12.

[0031] 3): After the operation is completed, the sliding locking frame 10 presses the bearing plate 11 against the assembly frame 7. The locking pin 15 automatically engages with the locking hole 19 under the action of the spring 14, fixing the locking frame 10 between the frames 9 to prevent the touch screen 8 from shaking due to vibration when the equipment is running.

[0032] In summary, this dual-arm robotic intelligent forklift, through the design of the storage slot 2 and the lifting assembly frame 7, provides a concealable protective space for the touch screen display 8. During transportation, the hydraulic cylinder 5 drives the lifting plate 6 to descend, storing the assembly frame 7 along with the touch screen display 8 into the storage slot 2 on top of the forklift body 1. At this time, the cover plate 21 and the storage slot 2 are closed, forming a physical protective barrier to prevent the touch screen display 8 from being directly exposed to the outside world. This design protects the touch screen display 8 from bumps, collisions, and dust corrosion during transportation. For example, when transporting multiple devices stacked together, the structure of the storage slot 2 can withstand the pressure of the devices above, preventing the touch screen display 8 from being crushed. This effectively solves the protective defects of traditional exposed designs. The locking frame 10 and the snap-fit ​​pin 15 structure of this device ensure the stability and ease of operation of the touch screen display 8 in the working state. During operation, hydraulic cylinder 5 pushes lifting plate 6 to a predetermined height. Control panel 13 compresses spring 14, causing locking pin 15 to disengage from locking hole 19 of locking frame 10, thus releasing the locking frame 10 and facilitating disassembly and maintenance of camera 12. After operation, sliding locking frame 10 causes support plate 11 to press against assembly frame 7. Locking pin 15 automatically engages with locking hole 19 under the action of spring 14, fixing locking frame 10 between frames 9 and preventing touch screen 8 from shaking due to vibration during equipment operation. Simultaneously, the engagement of locking plate 16 with assembly frame 7 and the support plate 18 supporting lifting plate 6 further enhance the stability of the overall structure, ensuring reliable connection of touch screen 8 during forklift movement or robotic arm operation, improving the safety and reliability of human-machine interaction.
