Description

Technical Field

[0001] This invention relates to the field of automated transport platform trolley technology, and particularly to an automated transport platform trolley based on intelligent AGV. Background Technology

[0002] Intelligent AGV is short for "intelligent automated guided vehicle". Essentially, it is an intelligent mobile robot that can autonomously complete material transportation, path planning, and environmental obstacle avoidance without human intervention. Its core is to replace manual labor to realize the automated material flow in scenarios such as warehousing and production through a closed-loop system of "perception-decision-execution".

[0003] In industrial production, warehousing and logistics, automated material transportation is a key link in improving operational efficiency and reducing labor costs. Intelligent AGV automated transport platform trolleys, as core execution equipment, have been widely used to replace traditional manual handling and fixed-track transport equipment.

[0004] When existing equipment is in operation, it may collide with materials that are suddenly scattered on the ground, temporarily stacked tool cabinets, or original fixed obstacles that are moved. Since most of these equipment only have a single transportation function, the impact force will be directly applied to the equipment during the collision, which may cause deformation or breakage of the AGV's sensors, navigation modules, drive wheels, or body frame, requiring repair or replacement of parts and increasing equipment maintenance costs. Therefore, we propose an intelligent AGV automated transport platform trolley to solve the above problems. Summary of the Invention

[0005] The main objective of this invention is to provide a vehicle based on an intelligent AGV (Automated Guided Vehicle) platform, which can effectively solve the above problems.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A smart AGV automated transport platform trolley includes a transport vehicle body, a lifting support platform installed on the top of the transport vehicle body, square grooves on the left and right ends of the transport vehicle body, buffer components on the left and right sides of the transport vehicle body, and disassembly and assembly components on the left and right sides of the transport vehicle body.

[0007] Preferably, the two buffer components are arranged symmetrically with the center of the transport vehicle body as the left and right points. Each buffer component includes a connecting seat, and the side of the connecting seat closest to the center of the transport vehicle body is set with an inclined surface. The outer surface of the connecting seat is inserted into the inner wall of the square groove on the same side.

[0008] Preferably, two hollow frames are installed at the end of the connecting seat away from the center of the transport vehicle body. A round rod is installed on the inner surface of each of the two hollow frames. A sliding block is slidably connected to the outer surface of each of the two round rods. A rotating rod is rotatably connected to the inner wall of each of the two sliding blocks on the side away from the center of the transport vehicle body. A buffer plate is rotatably connected to the outer surface of each of the two rotating rods on the side away from the connecting seat.

[0009] Preferably, spring 1 is sleeved on the outer surface of both round rods, and the ends of the two spring 1 that are close to each other are fixedly connected to the end of the sliding block on the same side that is close to the center of the hollow frame, while the ends of the two spring 1 that are far from each other are fixedly connected to the inner surface of the hollow frame on the same side.

[0010] Preferably, a damper is installed at the end of the connecting seat away from the center of the transport vehicle body, and the output end of the damper is fixedly connected to the side of the buffer plate on the same side that is closer to the center of the transport vehicle body.

[0011] Preferably, the two disassembly and assembly components are arranged symmetrically with the center of the transport vehicle body as the left and right points. Each disassembly and assembly component includes two sliding frames. Two convex grooves are provided on the left and right sides of the transport vehicle body. The outer surfaces of the two sliding frames are slidably connected to the inner walls of the convex grooves on the same side.

[0012] Preferably, a connecting frame is installed at the end of each of the two sliding frames away from the center of the transport vehicle body, a sliding rod is slidably connected to the inner wall of each of the two sliding frames, a locking block is installed at the end of each of the two sliding rods that are close to each other, and insertion holes are opened on the front and back of each of the two connecting seats, and the outer surface of each of the two locking blocks is inserted into the inner wall of the insertion hole on the same side.

[0013] Preferably, spring 2 is sleeved on the outer surface of each of the two sliding rods, and the ends of the two spring 2 that are close to each other are fixedly connected to the end of the locking block on the same side away from the center of the connecting seat. The ends of the two spring 2 that are far from each other are fixedly connected to the end of the sliding frame on the same side close to the connecting seat. The top of the transport vehicle body is provided with four sliding grooves, and U-shaped frames are slidably connected to the inner walls of the four sliding grooves. The inner surfaces of the four U-shaped frames are engaged with the top outer surface of the connecting frame on the same side.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention incorporates a buffer component. Specifically, when the device collides with an obstacle or other object during operation, the object first contacts the corresponding buffer plate. A spring then buffers and offsets the impact force on the buffer plate, preventing the impact force from acting directly on the device during the collision. This protects the AGV body, sensors, and other hardware, reduces component damage and repair frequency, and lowers equipment maintenance costs.

[0015] 2. This invention, by setting up a disassembly and assembly component, specifically by pushing two U-shaped frames to move two locking blocks, can remove the restriction on the connecting seat, allowing the buffer component to be directly removed and replaced. This not only quickly restores the AGV's transportation function and avoids affecting the material supply of the entire production line due to equipment downtime, ensuring stable production processes, but also eliminates the need for highly skilled maintenance personnel. Ordinary on-site staff can complete the replacement after simple training, reducing reliance on professional manpower. Attached Figure Description

[0018] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0019] Example 1, as Figure 1-6 As shown, a vehicle based on an intelligent AGV automated transport platform includes a transport vehicle body 1. A lifting support platform 11 is installed on the top of the transport vehicle body 1. Square grooves 12 are provided on both the left and right ends of the transport vehicle body 1. Buffer components 2 are provided on both the left and right sides of the transport vehicle body 1. Disassembly and assembly components 3 are provided on both the left and right sides of the transport vehicle body 1.

[0020] Specifically, in order to reduce equipment maintenance costs, see [reference needed]. Figure 3 and Figure 4In this embodiment, the two buffer components 2 are arranged symmetrically with the center of the transport vehicle body 1 as the left and right points. The buffer component 2 includes a connecting seat 21. The side of the connecting seat 21 closest to the center of the transport vehicle body 1 is set with an inclined surface. The outer surface of the connecting seat 21 is inserted into the inner wall of the square groove 12 on the same side.

[0021] Further reading Figure 3 and Figure 4 In this embodiment, two hollow frames 22 are installed at the end of the connecting seat 21 away from the center of the transport vehicle body 1. Round rods 221 are installed on the inner surface of the two hollow frames 22. Sliding blocks 222 are slidably connected to the outer surface of the two round rods 221. Rotating rods 224 are rotatably connected to the inner wall of the side of the two sliding blocks 222 away from the center of the transport vehicle body 1. Buffer plates 23 are rotatably connected to the outer surface of the side of the two rotating rods 224 away from the connecting seat 21.

[0022] Further reading Figure 4 In this embodiment, springs 223 are sleeved on the outer surfaces of the two round rods 221. The ends of the two springs 223 that are close to each other are fixedly connected to the end of the sliding block 222 on the same side that is close to the center of the hollow frame 22. The ends of the two springs 223 that are far apart from each other are fixedly connected to the inner surface of the hollow frame 22 on the same side.

[0023] Further reading Figure 3 In this embodiment, a damper 24 is installed at the end of the connecting seat 21 away from the center of the transport vehicle body 1, and the output end of the damper 24 is fixedly connected to the side of the buffer plate 23 on the same side that is close to the center of the transport vehicle body 1.

[0024] During implementation, when the device collides with an obstacle or other object during operation, the object will first contact the corresponding buffer plate 23. The impacted buffer plate 23 will move towards the transport vehicle body 1. When the buffer plate 23 moves, it will drive the two rotating rods 224 to rotate. When the rotating rods 224 rotate, they will push the sliding block 222 to slide on the outer surface of the corresponding round rod 221. When the sliding block 222 slides, it will compress the spring 223 and cause it to deform. The deformed spring 223 will generate a certain elastic force. As the degree of deformation of the spring 223 increases, the elastic force it generates will gradually increase, which can buffer and offset the impact force on the buffer plate 23, avoiding the impact force from acting directly on the device during the collision. This can protect the AGV body, sensors and other hardware, reduce component damage and maintenance frequency, and reduce equipment maintenance costs.

[0025] Example 2: This example is based on Example 1 and includes a disassembly / assembly component.

[0026] Specifically, to enable quick and easy replacement of the buffer components, please refer to... Figure 5 and Figure 6 In this embodiment, the two disassembly and assembly components 3 are arranged symmetrically with the center of the transport vehicle body 1 as the left and right points. The disassembly and assembly components 3 include two sliding frames 31. Two convex grooves are opened on the left and right sides of the transport vehicle body 1. The outer surfaces of the two sliding frames 31 are slidably connected to the inner walls of the convex grooves on the same side.

[0027] Further reading Figure 6 In this embodiment, a connecting frame 311 is installed at the end of each of the two sliding frames 31 that is away from the center of the transport vehicle body 1. A sliding rod 312 is slidably connected to the inner wall of each of the two sliding frames 31. A locking block 32 is installed at the end of each of the two sliding rods 312 that is close to each other. Insertion holes are opened on the front and back of each of the two connecting seats 21. The outer surface of each of the two locking blocks 32 is inserted into the inner wall of the insertion hole on the same side.

[0028] Further reading Figure 6 In this embodiment, springs 313 are sleeved on the outer surfaces of the two sliding rods 312. The ends of the two springs 313 that are close to each other are fixedly connected to the ends of the locking blocks 32 on the same side away from the center of the connecting seat 21. The ends of the two springs 313 that are far from each other are fixedly connected to the ends of the sliding frames 31 on the same side close to the connecting seat 21. The top of the transport vehicle body 1 is provided with four sliding grooves. U-shaped frames 33 are slidably connected to the inner walls of the four sliding grooves. The inner surfaces of the four U-shaped frames 33 are engaged with the top outer surface of the connecting frame 311 on the same side.

[0029] During implementation, when the buffer assembly 2 is damaged and needs to be replaced, firstly, push the two U-shaped brackets 33 to slide in the inner wall of the corresponding sliding groove so that their inner surfaces separate from the outer surface of the corresponding connecting bracket 311, thereby releasing the restriction on the connecting bracket 311. Push the two connecting brackets 311 away from each other. When the connecting brackets 311 move, they will drive the sliding bracket 31 to slide in the inner wall of the corresponding convex groove. When the sliding bracket 31 slides, it will drive the sliding rod 312 to move. When the sliding rod 312 moves, it will drive the locking block 32 to move. When the locking block 32 moves a certain distance, its outer surface will separate from the inner wall of the corresponding insertion hole. By driving the two locking blocks 32 to move, the restriction on the connecting seat 21 can be released, allowing the buffer assembly 2 to be directly removed for replacement. After the buffer assembly 2 is removed, push the two connecting brackets 311 back to their original positions and pass them through the U-shaped brackets 33. The new connector 21 is reinserted into the inner wall of the square groove 12. During the insertion process, the connector 21 will contact the surfaces of the two locking blocks 32. Since the contact surfaces of the connector 21 and the two locking blocks 32 are both set at an angle, the continuous movement of the connector 21 will push the two locking blocks 32 to move. After the connector 21 is installed, the deformed spring 2 313 will push the locking blocks 32 into the inner wall of the insertion hole due to the elastic force, thus reinserting the connector 21. This allows for quick and convenient disassembly and replacement of the buffer assembly 2. It can not only quickly restore the AGV's transportation function and avoid the impact of equipment shutdown on the material supply of the entire production line, ensuring the stability of the production process, but also eliminates the need for highly skilled maintenance personnel. Ordinary on-site staff can complete the replacement after simple training, reducing the reliance on professional manpower.

[0030] The working principle of this invention is as follows: When the device collides with an obstacle or other object during operation, the object will first come into contact with the corresponding buffer plate 23. The buffer plate 23, which is impacted, will move towards the transport vehicle body 1. When the buffer plate 23 moves, it will drive the two rotating rods 224 to rotate. When the rotating rods 224 rotate, they will push the sliding block 222 to slide on the outer surface of the corresponding round rod 221. When the sliding block 222 slides, it will compress the spring 223 and cause it to deform. The deformed spring 223 will generate a certain elastic force. As the degree of deformation of the spring 223 increases, the elastic force it generates will gradually increase, which can buffer and offset the impact force on the buffer plate 23, avoiding the impact force from acting directly on the device during the collision. This can protect the AGV body, sensors and other hardware, reduce component damage and maintenance frequency, and reduce equipment maintenance costs.

[0031] When the buffer assembly 2 is damaged and needs to be replaced, firstly, push the two U-shaped brackets 33 to slide in the inner wall of the corresponding sliding groove so that their inner surfaces separate from the outer surface of the corresponding connecting bracket 311, thereby releasing the restriction on the connecting bracket 311. Push the two connecting brackets 311 away from each other. When the connecting brackets 311 move, they will drive the sliding bracket 31 to slide in the inner wall of the corresponding convex groove. When the sliding bracket 31 slides, it will drive the sliding rod 312 to move. When the sliding rod 312 moves, it will drive the locking block 32 to move. When the locking block 32 moves a certain distance, its outer surface will separate from the inner wall of the corresponding insertion hole. By driving the two locking blocks 32 to move, the restriction on the connecting seat 21 can be released, allowing the buffer assembly 2 to be directly... The buffer assembly 2 is removed and replaced. After removing the buffer assembly 2, the two connecting brackets 311 are pushed back to their original positions and re-restrained by the U-shaped bracket 33. The new connecting seat 21 is then reinserted into the inner wall of the square groove 12. During the insertion process, the connecting seat 21 will contact the surfaces of the two locking blocks 32. Since the contact surfaces of the connecting seat 21 and the two locking blocks 32 are both set at an angle, the continuous movement of the connecting seat 21 will push the two locking blocks 32 to move. After the connecting seat 21 is installed, the deformed spring 2 313 will push the locking blocks 32 into the inner wall of the insertion hole due to the elastic force, thus re-restraining the connecting seat 21. This allows for quick and convenient disassembly and replacement of the buffer assembly 2, which not only quickly restores the AGV's transportation function and avoids affecting the material supply of the entire production line due to equipment shutdown, ensuring the stability of the production process, but also eliminates the need for highly skilled maintenance personnel. Ordinary on-site staff can complete the replacement after simple training, reducing the reliance on professional manpower.
