Description

Technical Field

[0001] This utility model relates to the field of AGV warehousing technology, specifically to an AGV warehousing and handling vehicle with a side-shifting buffer structure. Background Technology

[0002] In the warehousing and logistics sector, AGVs (Automated Guided Vehicles) have become core equipment for cargo handling and retrieval operations due to their advantages of automation, efficiency, and intelligence. They are widely used in scenarios such as automated warehouses, smart workshops, and e-commerce sorting centers. These devices typically adjust the working height through a lifting mechanism on the vehicle body, and work in conjunction with a side-shifting mechanism to drive the lateral movement of the L-shaped arms, allowing them to precisely insert into the bottom of the pallet, thus achieving automated handling and transfer of goods.

[0003] Existing AGV warehouse handling vehicles are typically equipped with side-shifting mechanisms and extender arm assemblies. The side-shifting mechanism drives the extender arm to adjust its position laterally, enabling precise docking and handling of shelves or goods at different intervals. However, in actual operation, due to the complexity of the warehouse environment, such as uneven ground, shelf installation errors, deviations in the work path, or misalignment of goods, when the side-shifting mechanism drives the extender arm to move laterally, the extender arm or side-shifting mechanism is prone to rigid collisions with shelf uprights, adjacent goods, or warehouse facilities. This can not only cause pallet damage and goods tipping over, but also lead to accelerated wear on the transmission components of the side-shifting mechanism, shortening the service life of the equipment. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model discloses an AGV warehouse handling vehicle with a side shift buffer structure. The technical solution adopted is as follows: it includes a vehicle body, a lifting mechanism is fixedly installed on the side of the vehicle body, a side shift mechanism is fixedly installed on the lifting mechanism, two L-shaped insert arms are fixedly connected to the side of the side shift mechanism, two mounting plates are fixedly installed on the other side of the side shift mechanism, and a buffer mechanism is installed on the two mounting plates.

[0005] The buffer mechanism includes a first rotating plate, a second rotating plate, a buffer, a support plate, a movable column, and a movable groove. Two first rotating plates are provided, with one side of each first rotating plate rotatably connected to the opposite side of one end of each mounting plate. Two second rotating plates are also provided, with one side of each second rotating plate rotatably connected to the opposite side of one end of each support plate. The support plate is U-shaped, and movable grooves are provided on the other side of both the support plate and the other side of both mounting plates. Movable columns are fixedly connected to the other sides of both the first and second rotating plates. The movable columns on the first and second rotating plates are respectively located within the movable grooves on the sides of the mounting plate and the support plate. The sides of the middle portions of the first and second rotating plates are rotatably connected. The buffer is fixedly installed on the side of the lateral movement mechanism and is connected to both the first and second rotating plates. As a preferred embodiment of this utility model, the buffer includes a fixed plate, a damping rod, a spring, a rotating block, and a fixed rod. The fixed plate is fixedly installed on the side of the lateral movement mechanism. The side of the fixed plate is fixedly connected to one end of the damping rod, and the other end of the damping rod is fixedly connected to the side of the rotating block. A spring is sleeved on the outside of the damping rod, and the two ends of the spring are fixedly connected to the opposite sides of the fixed plate and the rotating block, respectively. A fixed rod is rotatably installed in the through hole on the side of the rotating block, and the two ends of the fixed rod are fixedly connected to the sides of the two second rotating plates near the moving groove, respectively.

[0006] As a preferred embodiment of this utility model, the damping rod is a hydraulic damping rod.

[0007] As a preferred embodiment of this utility model, the side of the support plate is fixedly connected to the side of the rubber pad.

[0008] As a preferred embodiment of this utility model, a warning light is fixedly installed in the groove on the side of the support plate, and the warning light is a vibration-sensing light.

[0009] The beneficial effects of this utility model are as follows: 1. When the extension arm or side-shifting mechanism encounters obstacles such as shelf uprights or adjacent goods, the obstacle first contacts the support plate. The support plate, under force, drives the second rotating plate to rotate around the connection point. The second rotating plate and the first rotating plate are linked by a central rotating connection, causing the moving column at the other end of both to slide along the moving groove of the mounting plate and the support plate. At the same time, the second rotating plate pushes the rotating block through the fixed rod, causing the damping rod to extend and retract and stretch the spring. The hydraulic damping rod slowly releases the impact force through hydraulic damping, while the spring further absorbs and stores the impact energy through elastic deformation. The two work together to transform rigid collisions into flexible buffers, effectively preventing pallet damage and goods tipping over. At the same time, it completely solves the problem of accelerated wear of the transmission components of the side-shifting mechanism caused by rigid collisions.

[0010] 2. The hydraulic damping rod possesses stable damping and buffering performance. Combined with the elastic return function of the spring, it can maintain the stability of the buffering effect over a long period, avoiding frequent replacement of buffering components. The rubber pad can absorb some of the instantaneous impact force, achieving initial buffering.

[0011] 3. The warning light can automatically light up when the buffer mechanism collides, sending a warning signal to the surrounding operators and equipment, which facilitates timely investigation of operational abnormalities and avoids the escalation of collision accidents. Especially in scenarios where personnel and AGVs work together, it greatly improves operational safety. Attached Figure Description

Detailed Implementation

[0017] Example 1

[0018] like Figures 1 to 4 As shown, this utility model discloses an AGV warehouse handling vehicle with a side-shifting buffer structure. The technical solution adopted is as follows: it includes a vehicle body 1, a lifting mechanism 2 is fixedly installed on the side of the vehicle body 1, a side-shifting mechanism 3 is fixedly installed on the lifting mechanism 2, two L-shaped insert arms 4 are fixedly connected to the side of the side-shifting mechanism 3, two mounting plates 8 are fixedly installed on the other side of the side-shifting mechanism 3, and a buffer mechanism 5 is installed on the two mounting plates 8.

[0019] The buffer mechanism 5 includes a first rotating plate 51, a second rotating plate 52, a buffer 53, a support plate 54, a movable column 55, and a movable groove 56. Two first rotating plates 51 are provided, with one side of each plate 51 rotatably connected to the opposite side of one end of each mounting plate 8. Two second rotating plates 52 are also provided, with one side of each plate 52 rotatably connected to the opposite side of one end of each support plate 54. The side of the support plate 54 is fixedly connected to the side of a rubber pad 6. The rubber pad 6 absorbs some of the instantaneous impact force, achieving initial buffering. A warning light 7 is fixedly installed in the groove on the side of the support plate 54. The warning light 7 is a vibration-sensitive light that automatically illuminates when the buffer mechanism 5 collides, alerting the user. Warning signals are issued to surrounding operators and equipment to facilitate timely detection of operational abnormalities and prevent the escalation of collision accidents. This significantly improves operational safety, especially in scenarios where personnel and AGVs work together. The support plate 54 is U-shaped, and movable slots 56 are provided on the other side of the support plate 54 and the other side of the two mounting plates 8. Movable columns 55 are fixedly connected to the other side of the two first rotating plates 51 and the two second rotating plates 52. The movable columns 55 on the two first rotating plates 51 and the two second rotating plates 52 are located in the movable slots 56 on the sides of the mounting plates 8 and the support plate 54, respectively. The sides of the first rotating plates 51 and the second rotating plates 52 are rotatably connected in the middle. The buffer 53 is fixedly installed on the side of the side-shifting mechanism 3. The buffer 53 is connected to the first rotating plate 51 and the second rotating plate 52. The buffer 53 includes a fixed plate 531, a damping rod 532, a spring 533, a rotating block 534, and a fixed rod 535. The fixed plate 531 is fixedly installed on the side of the lateral shifting mechanism 3. The side of the fixed plate 531 is fixedly connected to one end of the damping rod 532, and the other end of the damping rod 532 is fixedly connected to the side of the rotating block 534. A spring 533 is sleeved on the outside of the damping rod 532. The damping rod 532 is a hydraulic damping rod, which has stable damping and buffering performance. Combined with the elastic restoring function of the spring 533, it can maintain the stability of the buffering effect for a long time. The two ends of the spring 533 are respectively connected to the fixed plate 531 and the rotating block 534. A fixed rod 535 is rotatably installed in the through hole on the side of the rotating block 534. The two ends of the fixed rod 535 are fixedly connected to the side of the two second rotating plates 52 near the moving groove 56. When the insert arm 4 or the side-moving mechanism 3 encounters obstacles such as shelf columns or adjacent goods, the obstacles first contact the support plate 54. The support plate 54 is forced to rotate the second rotating plate 52 around the connection point. The second rotating plate 52 and the first rotating plate 51 are linked by a central rotating connection, which drives the moving column 55 at the other end of both to slide along the moving groove 56 of the mounting plate 8 and the support plate 54. At the same time, the second rotating plate 52 pushes the rotating block 534 through the fixed rod 535, causing the damping rod 532 to extend and compress and stretch 533.The damping rod 532 slowly releases the impact force through hydraulic damping, while the spring 533 further absorbs and stores the impact energy through elastic deformation. Together, they transform rigid collisions into flexible buffers, effectively preventing pallet damage and cargo tipping. At the same time, they completely solve the problem of accelerated wear of the transmission components of the side-shifting mechanism caused by rigid collisions.

[0020] The working principle of this utility model is as follows: The vehicle body 1 will autonomously move to the target goods / shelf position according to the preset path or real-time navigation instructions to complete the positioning. Then, the lifting mechanism 2 on the side of the vehicle body 1 will be activated, adjusting the side-shifting mechanism 3 and the two L-shaped insert arms 4 to a height that matches the bottom of the pallet. The side-shifting mechanism 3 will then drive the insert arms 4 to move laterally to accurately insert into the bottom of the pallet. The lifting mechanism 2 will further lift the insert arms 4 and the goods to complete the pickup. Afterward, the vehicle body 1 will carry the goods along the planned path to the target storage location. The lifting mechanism 2 will adjust its height to match the height of the shelf. After the side-shifting mechanism 3 finely adjusts the position of the insert arms 4, the lifting mechanism 2 will lower to place the goods smoothly, completing a normal handling operation. During operation; when the lateral shifting mechanism 3 drives the insert arm 4 to move laterally, if the insert arm 4 or the lateral shifting mechanism 3 touches an obstacle due to uneven ground, shelf errors, or other factors, the obstacle will first contact the rubber pad 6 on the side of the support plate 54. The rubber pad 6 absorbs part of the instantaneous impact force through elastic deformation to achieve initial buffering. The remaining impact force pushes the U-shaped support plate 54 to move towards the lateral shifting mechanism 3, thereby driving the two second rotating plates 52 rotatably connected to it to rotate around the connection point. Since the first rotating plate 51 and the second rotating plate 52 are rotatably connected in the middle, the second rotating plate 52 will move synchronously with the first rotating plate 51. The moving columns 55 fixed at the other ends of both are respectively installed along the installation The sliding grooves 56 on the sides of the plate 8 and the support plate 54 provide stable guidance for the movement of the rotating plate to prevent jamming. At the same time, the second rotating plate 52 pushes the rotating block 534 through the fixed rod 535, causing the damping rod 532 of the buffer 53 on the side shift mechanism 3 to stretch and the outer spring 533 to stretch. The damping rod 532 slowly releases the impact force through internal hydraulic damping, and the spring 533 further absorbs the impact energy through elastic deformation. The two work together to transform rigid collision into flexible buffering, avoiding pallet damage, cargo tipping, and excessive wear of the transmission components of the side shift mechanism. When the collision risk is eliminated, the spring 533 releases elastic potential energy to pull the rotating block 534 to move in the opposite direction, driving the damping rod 534 to move in the opposite direction. The rod 532 resets, and the reset force is transmitted to the support plate 54 through the fixed rod 535, the second rotating plate 52, and the first rotating plate 51, so that the support plate 54 and the rubber pad 6 return to their initial positions. The stable damping performance of the damping rod 532 and the persistent reset capability of the spring 533 ensure the long-term stability of the buffering effect. At the same time, the vibration of the support plate 54 will trigger the vibration-sensing warning light 7 in the groove on its side to automatically light up, sending an immediate warning signal to the surrounding operators and other AGV equipment. This facilitates timely investigation of abnormalities such as shelf misalignment and incorrect goods placement, and avoids the escalation of collision accidents. It significantly improves the safety of operations, especially in scenarios where personnel and AGVs work together.
