Description

Technical Field

[0001] This utility model relates to the field of AGV (Automated Guided Vehicle) technology, and more specifically, to an AGV and its fork arm structure. Background Technology

[0002] AGVs are widely used in logistics, warehousing and other industries to reduce labor costs and improve work efficiency. Traditional AGV designs involve mounting separate forks on the frame assembly. This requires a power source for both fork extension and lifting, resulting in a complex structure. Furthermore, the open fork structure makes it difficult to pick up truncated trays, making it unsuitable for applications involving picking up truncated trays in warehousing or transportation. To address this, we propose an AGV and its fork structure. The overall structure of the fork meets the requirements for picking up truncated trays. By adding a mast assembly, the power source required for the fork to operate is reduced, further increasing synchronization and work efficiency. Utility Model Content

[0024] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] This utility model provides an AGV trolley 4 and its fork arm structure, such as Figure 1 As shown, it includes: a gantry assembly 1 for connection and installation with the AGV trolley 4 and at least one fork arm assembly 2 for lifting and picking up a pallet; the gantry assembly 1 includes: a support frame 11 for connection and installation with the AGV trolley 4, a first drive unit 12 for moving the support frame 11, and a clamping unit 25 for preventing the first drive unit 12 from spinning idly; the support frame 11 is provided with a sliding groove; one end of the fork arm assembly 2 is slidably placed in the sliding groove.

[0026] Specifically, the support frame 11 is connected to the AGV trolley 4. The drive unit drives the support frame 11 to move on the AGV trolley 4, thereby driving the fork arm assembly 2 connected to the support frame 11 to move in the X-axis direction, realizing the steps of extending and retracting the fork arm assembly 2. At the same time, the clamping unit 25 provides a certain downward force along the direction of gravity to the drive unit, so that the drive unit and the AGV trolley 4 are in close contact, avoiding the drive wheel 122 from spinning idly and failing to achieve the extension and retraction of the fork arm, further improving the scene adaptability.

[0027] Further, the fork arm assembly 2 includes: a fork arm body 21 for supporting a pallet fork, a connecting unit 22 for connecting the fork arm body 21 and the support frame 11, a lifting unit 23 for lifting the fork arm body 21, and a second drive unit 24 for driving the lifting unit 23; one end of the connecting unit 22 is detachably connected to the fork arm body 21, and the other end of the connecting unit 22 is slidably placed in the sliding groove; the second drive unit 24 is detachably connected to the fork arm body 21, and the output end of the second drive unit 24 is fixedly connected to the lifting unit 23; the lifting unit 23 is detachably connected to the fork arm body 21 and is located at the bottom of the fork arm body 21.

[0028] In Example 1, as Figure 1-2 As shown, the fork arm body 21 and the support frame 11 are connected to each other by the connecting unit 22. The driving unit is set in the fork arm body 21. The lifting unit 23 set on the fork arm body 21 is driven to lift the fork arm body 21. During the lifting process of the fork arm body 21, the end of the connecting unit 22 that is slidably placed in the slide groove 111 of the support frame 11 plays a certain guiding role. When the fork arm body 21 moves in the Z-axis, it avoids displacement deviation that would cause it to malfunction.

[0029] Further, the lifting unit 23 includes: a plurality of lifting components 3; the plurality of lifting components 3 are respectively fixedly connected to the output end of the second drive unit 24; the lifting component 3 includes: a first transmission rod 31, a second transmission rod 32, a first sliding block 33, a second sliding block 34, two first scissor forks 35, two second scissor forks 36 corresponding to the two first scissor forks 35, and a support plate 37; the first transmission rod 31 and the second transmission rod 32 are respectively fixedly connected to the output end of the second drive unit 24; the first transmission rod 31 is threadedly connected to the first sliding block 33; the second transmission rod 32 is threadedly connected to the second sliding block 34; the first sliding block 33 and the second sliding block 34 can be slidably connected to the fork arm body 21; the first scissor fork 35 and the corresponding second scissor fork 36 are hinged to each other to form a scissor fork knot. The structure includes: one end of the first scissor lift 35 is hinged to the first sliding block 33; one end of the second scissor lift 36 is hinged to the second sliding block 34; the other end of the first scissor lift 35 is provided with a first connecting wheel 351; the other end of the second scissor lift 36 is provided with a second connecting wheel 361; the support plate 37 is provided with: two first limiting blocks 39 corresponding to the first scissor lift 35 and two second limiting blocks 310 corresponding to the second scissor lift 36; the first limiting blocks 39 cooperate with the support plate 37 to form a first limiting area 311; the second limiting blocks 310 cooperate with the support plate 37 to form a second limiting area 312; the first connecting wheel 351 is slidably placed in the corresponding first limiting area 311; the second connecting wheel 361 is slidably placed in the corresponding second limiting area 312.

[0030] In Example 2, as Figure 2 As shown, the lifting unit 23 is composed of several lifting components 3, and the lifting and lowering of the fork arm body 21 is achieved through the telescopic scissor fork of the lifting components 3.

[0031] The second drive unit 24 drives the first transmission rod 31 and the second transmission rod 32 to rotate. The threaded connection between the first transmission rod 31 and the first sliding block 33 is a positive thread connection, and the threaded connection between the second transmission rod 32 and the second sliding block 34 is a negative thread connection. Thus, when rotating, the first sliding block 33 and the second sliding block 34 slide on the fork body 21, moving closer or further apart. This drives the first scissor fork 35 connected to the first sliding block 33 and the second scissor fork 36 connected to the second sliding block 34 to extend and retract, thereby driving the support plate 37 to rise and fall.

[0032] When the scissor structure composed of the first scissor fork 35 and the second scissor fork 36 extends, causing the support plate 37 to descend and contact the ground, the support plate 37 serves as the support base point. As the scissor structure continues to extend and retract, the fork arm body 21 is lifted.

[0033] When the fork arm body 21 is in the raised state, the scissor structure consisting of the first scissor fork 35 and the second inspection fork retracts, causing the fork arm body 21 to descend with the support plate 37 and the ground contact point as the support base. When it descends to the lowest point connected to the support frame 11, the fork arm body 21 has finished descending. At this time, the scissor structure continues to retract, using the connection point between the fork arm body 21 and the support frame 11 as the support base, and retracts the support plate 37, completing the entire descent and retraction step.

[0034] Specifically, such as Figure 3 As shown, the connection between the first scissor fork 35 and the second scissor fork 36 and the support plate 37 is achieved through the cooperation of the first limiting block 39 and the second limiting block 310, which allows the first connecting wheel 351 and the second connecting wheel 361 to slide on the support plate 37. This ensures that the support plate 37 is centered when the fork body 21 is retracted during the up and down movement of the support plate 37. This ensures that when the zigzag pallet is lifted, the support plate 37 extends out of the gap of the zigzag pallet, avoiding collision with the zigzag pallet and ensuring the reliability of the support plate 37 as a support base.

[0035] In other embodiments, the support plate 37 can be removed, and the first connecting wheel 351 on the first scissor fork 35 and the second connecting wheel 361 on the second scissor fork 36 can be used as support base points to achieve normal operation of the fork arm body 21.

[0036] Furthermore, a plurality of guide pulleys 38 are provided on both sides of the first sliding block 33 and the second sliding block 34; guide grooves 211 corresponding to the guide pulleys 38 are provided on both side walls of the fork arm body 21; the plurality of guide pulleys 38 are slidably placed in the corresponding guide grooves 211.

[0037] In Example 3, as Figure 2 As shown, when the second drive unit 24 drives the first transmission rod 31 and the second transmission rod 32, thereby causing the first sliding block 33 and the second sliding block 34 to slide, the guide pulleys 38 on the first sliding block 33 and the second sliding block 34 slide in the corresponding guide grooves 211, thereby limiting the sliding process of the first sliding block 33 and the second sliding block 34, and preventing the displacement from exceeding the maximum limit range, which would cause the situation of not working properly to occur.

[0038] Specifically, the fork arm body 21 is an integral fork arm structure consisting of a fork arm cover 212 and a fork arm frame 213, and a guide groove 211 is provided on the fork arm frame 213.

[0039] Furthermore, the connecting unit 22 includes: a connecting plate 221 and a plurality of guide wheels 222; one end of the connecting plate 221 is detachably connected to the fork arm body 21; the plurality of guide wheels 222 are disposed on the other end of the connecting plate 221; the plurality of guide wheels 222 are slidably placed in the groove 111.

[0040] In Example 4, as Figure 1 As shown, the fork arm assembly 2 and the support frame 11 are connected by the connecting plate 221, thereby suspending the fork arm assembly 2 on the support frame 11. When the fork arm assembly 2 moves in the Z-axis direction, the guide wheel 222 on the connecting plate 221 moves in the slide groove 111 of the support frame 11, thereby achieving a certain guiding effect and preventing the fork arm assembly 2 from shifting position during the lifting process, which would cause it to malfunction.

[0041] Further, the first drive unit 12 includes: a mounting frame 121, a drive wheel 122 for contacting the AGV trolley 4 frame, and a first drive member 123 for driving the drive wheel 122 to rotate; the mounting frame 121 is detachably connected to the support frame 11; the drive wheel 122 is rotatably connected to the mounting frame 121; the second drive member 241 is detachably connected to the mounting frame 121; and the output end of the second drive member 241 is drively connected to the drive wheel 122.

[0042] In embodiment five, the drive wheel 122 and the second drive member 241 are mounted on the support frame 11 by mounting bracket 121. In actual application, the drive wheel 122 is in contact with the frame assembly of the AGV trolley 4. The second drive member 241 drives the drive wheel 122 to rotate, thereby realizing the movement of the support frame 11 on the AGV trolley 4, thereby driving the fork arm assembly 2 to extend.

[0043] Further, the clamping unit 25 includes: a connecting frame 251, at least one guide block 252, at least one guide shaft 253 corresponding to the guide block 252, and at least one clamping spring 254 corresponding to the guide shaft 253; the connecting frame 251 is detachably connected to the support frame 11; one end of the guide shaft 253 is detachably connected to the connecting frame 251, and the other end is slidably connected to the guide block 252; the guide block 252 is detachably connected to the mounting frame 121; the clamping spring 254 is sleeved on the guide shaft 253; the clamping spring abuts against the guide block 252.

[0044] In Example 6, as Figure 4As shown, the guide block 252 is mounted on the mounting frame 121 by mounting the connecting bracket 251 on the support frame 11. The guide shaft 253 is located between the support frame 11 and the guide block 252. The abutment spring is sleeved on the guide shaft 253 and is in a compressed state. The clamping spring 254 provides a downward elastic force to the guide block 252 along the direction of gravity. Through the guide block 252 as a medium, the drive wheel 122 on the mounting frame 121 connected to the guide block 252 is always in contact with the AGV trolley 4, so as to avoid the occurrence of idle rotation.

[0045] Furthermore, the second drive unit 24 includes: a second drive member 241 for driving the first transmission rod 31 and the second transmission rod 32; the second drive member 241 is detachably connected to the fork arm body 21; the first transmission rod 31 and the second transmission rod 32 are respectively fixedly connected to the output end of the second drive member 241.

[0046] Specifically, the second drive component 241 is a lead screw motor, which is connected to the first transmission rod 31 and the second transmission rod 32 through the lead screw output end of the lead screw motor.

[0047] Optionally, the support frame 11 is further provided with at least one linear guide sliding block 6 for guiding the support frame 11 during its movement.

[0048] In other embodiments, such as Figure 1 and Figure 4 As shown, the AGV trolley 4 is equipped with a guide rail 5, which, through the sliding block 6 on the support frame 11, achieves a further guiding function, avoiding positional deviations during movement that could lead to malfunctions.

[0049] An AGV trolley 4 includes the fork arm structure of the AGV trolley 4 described above.

[0050] This utility model discloses an AGV trolley 4 and its fork arm structure. The fork arm assembly 2 moves along the X-axis direction via the gantry assembly 1, thus completing the fork arm extension step of the AGV trolley 4. This replaces the traditional fork arm extension structure built into the fork arm, reducing the power source. At the same time, the fork arm assemblies 2 connected on the same gantry assembly 1 can achieve better synchronous extension and retraction steps, further improving scene adaptability. When the fork arm assembly 2 is connected to the gantry assembly 1, it will not contact the ground, reducing the need for lifting structures or caster retraction structures in traditional designs, making the fork arm structure itself simpler. The structure of the fork arm assembly 2 is simpler, eliminating the traditional ground auxiliary wheel structure. At the same time, it improves the traditional fork arm's structure of opening the upper and lower plates as a whole, adopting a double scissor fork + support plate 37 structure, making the fork arm adaptable to the fork-lifting conditions of the grid tray, and fork-lifting the grid tray.

[0051] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
