Description

Technical Field

[0001] This utility model belongs to the field of AGV technology, and specifically relates to an AGV trolley for cargo. Background Technology

[0002] AGV is short for Automated Guided Vehicle, also known as automated guided vehicle or automated guided transport vehicle. It is an industrial vehicle that loads goods automatically or manually, travels automatically along a set route or pulls a cargo trolley to a designated location, and then loads and unloads goods automatically or manually.

[0003] In existing forklift-type AGVs, goods are lifted from pallets using forks and then transported to their destination. However, different goods on a pallet have different centers of gravity, and since the AGV does not limit the pallet during transport, the pallet shifts on the forks during movement and turning, further shifting the center of gravity of the goods on the pallet. This can ultimately lead to goods falling or the AGV tipping over. Therefore, designing a cargo AGV to address this problem is a current challenge we need to solve. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose an AGV (Automated Guided Vehicle) for cargo.

[0005] To achieve the above objectives, this utility model provides a cargo AGV trolley, including a trolley body, a fork arm slidably connected to one side of the trolley body, a connecting arm inserted into the bottom of the fork arm, and the connecting arm fixedly connected to one side of the trolley body; and a support assembly, which is used to assist the AGV trolley in supporting and limiting the pallet, and the support assembly is connected to the fork arm.

[0006] In the above technical solution, the support assembly further includes a mounting block fixedly connected to the outer wall of the fork arm, a support arm rotatably connected to the top of the mounting block, and a sleeve inserted into the inside of the support arm.

[0007] In the above technical solution, the outer wall of the sleeve is provided with an insert, and the inside of the support arm is provided with a first slot corresponding to the insert, and the insert is inserted into the first slot.

[0008] In the above technical solution, the sleeve is further provided with a sliding groove and a spiral groove inside. The sliding groove is fixedly connected to the end of the spiral groove away from the mounting block. A rotating rod is inserted into the inside of the sleeve. The rotating rod is rotatably connected to the inside of the mounting block. A slider is fixedly connected to the outer wall of the rotating rod. The slider is inserted into the inside of the spiral groove.

[0009] In the above technical solution, the outer wall of the rotating rod is provided with a straight groove, and a connector is slidably connected inside the straight groove. One end of the connector is fixedly connected to a spring, which is fixedly installed inside the mounting block and is located at the bottom of the sleeve.

[0010] In the above technical solution, further, an elastic element is inserted into the inside of the connector, the elastic element is fixedly installed inside the mounting block, and a second slot is provided inside the mounting block.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] By setting up support components, the pallet can be supported by the fork arms to increase the range of support and improve the stability of the pallet. At this time, the support arms can be placed against the two sides inside the pallet to limit the pallet and prevent it from shifting during transportation, thus affecting the stability of the goods on the pallet.

[0013] By incorporating a rotating rod and elastic element in the support assembly, the support assembly can be prevented from jamming due to its inability to rotate when the AGV inserts the fork arm into the bottom of a small pallet. Furthermore, the support arm can remain fixed to the mounting block, allowing it to limit the pallet's movement. This enables the support assembly to support and limit pallets of different sizes, thus expanding its applicability. Attached Figure Description

[0020] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] like Figures 1 to 2 The AGV (Automated Guided Vehicle) for goods shown includes a vehicle body 1, a fork arm 2 slidably connected to one side of the vehicle body 1, a connecting arm 3 inserted into the bottom of the fork arm 2, and the connecting arm 3 fixedly connected to one side of the vehicle body 1; and a support assembly, which is used to assist the AGV in supporting and limiting the pallet. The support assembly is connected to the fork arm 2, and the number of support assemblies is set to multiple and symmetrically installed on the outer wall of 102.

[0022] For example, 2 to Figure 5 As shown, the support assembly includes a mounting block 4 fixedly connected to the outer wall of the fork arm 2. A support arm 5 is rotatably connected to the top of the mounting block 4. A sleeve 6 is inserted into the inside of the support arm 5. An insert 7 is provided on the outer wall of the sleeve 6. A first slot 8 corresponding to the insert 7 is provided inside the support arm 5. The insert 7 is inserted into the first slot 8. A sliding groove 9 and a spiral groove 10 are provided inside the sleeve 6. The sliding groove 9 is fixedly connected to the end of the spiral groove 10 away from the mounting block 4. A rotating rod 11 is inserted into the inside of the sleeve 6. The rotating rod 11 is rotatably connected to the mounting block 4. Inside the mounting block 4, a slider 12 is fixedly connected to the outer wall of the rotating rod 11. The slider 12 is inserted into the spiral groove 10. A straight groove 13 is opened on the outer wall of the rotating rod 11. A connector 14 is slidably connected inside the straight groove 13. A spring 15 is fixedly connected to one end of the connector 14. The spring 15 is fixedly installed inside the mounting block 4. The spring 15 is located at the bottom of the sleeve 6. An elastic element 16 is inserted into the inside of the connector 14. The elastic element 16 is fixedly installed inside the mounting block 4. A second slot 17 is opened inside the mounting block 4.

[0023] Working Principle: When the AGV inserts the fork arm 2 into the bottom of the pallet and controls the fork arm 2 to rise and lift the pallet and the goods on it, because the sleeve 6 is higher than the fork arm 2, the sleeve 6 will be relatively squeezed by the bottom of the pallet. This causes the sleeve 6 to slide down through the insert 7 along the first slot 8 inside the support arm 5 and compress the spring 15, causing the sleeve 6 to slide down through the spiral groove 10 along the slider 12. The slider 12 drives the sleeve 6 to rotate through the spiral groove 10, which in turn drives the support arm 5 to rotate. This continues until the slider 12 moves to the connection point between the slide groove 9 and the spiral groove 10, at which point the support arm 5 stops rotating. At this point, the support arm 5 is perpendicular to the fork arm 2, which can work with the fork arm 2 to increase the support range of the pallet and improve the stability of the pallet. At this time, the support arm 5 can also abut against both sides inside the pallet to limit the pallet and prevent it from shifting during transportation, thus affecting the stability of the goods on the pallet. Afterwards, as the fork arm 2 continues to rise, the sleeve 6 is further squeezed by the spiral groove 10, causing the slider 6 to slide down through the spiral groove 10. 12 begins to slide along the inside of the slide groove 9. At this time, the slide groove 9 and the slider 12 move in the same direction, so the sleeve 6 will not rotate. The sleeve 6 slides along the inside of the slider 12 through the slide groove 9, causing the sleeve 6 to gradually approach and insert into the inside of the mounting block 4. The plug 7 on the sleeve 6 is then inserted into the second slot 17 inside the mounting block 4. At this time, the sleeve 6, through the plug 7, is inserted into the first slot 8 inside the support arm 5 and the second slot 17 inside the mounting block 4, respectively. This fixes the relative position of the support arm 5 and the mounting block 4, preventing the pallet from pushing the support arm 5 to rotate when the AGV trolley moves and turns with the pallet and goods. This would cause the limiting effect on the pallet to disappear, affecting the stability during transportation and preventing goods from falling or the AGV trolley from tipping over. It should be noted that since the support arm 5 is deformed during the process of the fork arm 2 rising and lifting the pallet, the rotation of the support arm 5 will not cause friction with the bottom of the pallet, thus avoiding excessive friction between the support arm 5 and the bottom of the pallet, which could affect deformation.

[0024] Furthermore, when the AGV inserts the fork arm 2 into the bottom of the small pallet, causing the support arm 5 to abut against both sides inside the pallet before it has rotated to be perpendicular to the fork arm 2, the support arm 5 is blocked and limited by the pallet. The support arm 5 limits the sleeve 6 through the first slot 8 and the plug 7. At this time, the slider 12 sliding inside the spiral groove 10 cannot drive the sleeve 6 to rotate through the spiral groove 10. Meanwhile, the sleeve 6 is relatively squeezed by the pallet, which increases the force exerted by the slider 12 on the rotating rod 11. This causes the rotating rod 11 to push the elastic element 16 to deform and open through the straight groove 13, stopping the force exerted on the rotating rod 11 through the straight groove 13. The obstruction causes the slider 12 to slide along the inside of the spiral groove 10, which in turn drives the rotating rod 11 to rotate. The rotating rod 11 then drives the spring 15 to twist through the straight groove 13 and the connector 14. After the support arm 5 is blocked by both sides inside the tray, the slider 12 drives the 11 to rotate, preventing the support assembly from being jammed. As the sleeve 6 continues to be squeezed relative to the bottom of the tray, the sleeve 6 begins to drive the insert 7 to insert into the inside of the second slot 17, fixing the support arm 5 on the mounting block 4. This allows the support arm 5 to limit the tray, enabling the support assembly to support and limit trays of different sizes, thus improving the applicability of the support assembly.

[0025] Furthermore, when the AGV transports the pallet and goods to the destination, and the AGV controls the fork arm 2 to descend and stop lifting the pallet, the sleeve 6 gradually loses the pressure of the pallet, allowing the spring 15 to reset and push the sleeve 6 to rise and reset. In turn, the sleeve 6 drives the support arm 5 to rotate and reset. It should be noted that if the rotating rod 11 is rotated, the spring 15 will reset by using the force stored in the torsion to push the rotating rod 11 to rotate and reset, allowing the support assembly to automatically reset and wait for the next operation.
