Description

Technical Field

[0001] This utility model belongs to the field of transportation technology, and in particular relates to a lifting and telescopic forklift AGV. Background Technology

[0002] AGV, or Automated Guided Vehicle, refers to a transport vehicle equipped with electromagnetic or optical automatic guidance devices. It can travel along a prescribed guidance path and has safety protection and various transfer functions. Most AGVs on the market are used for transporting materials, that is, they lift small objects by using a lifting structure protruding from the side of the vehicle body for transportation.

[0003] When the ground clearance of the bottom of the pallet is lower than the height of the top of the fork, the insertion end of the fork is usually sloping in order to facilitate the accurate and smooth insertion of the fork of the fork-type AGV into the ground clearance of the bottom of the pallet. In order to avoid the goods on the pallet suddenly tilting after the fork is fully inserted into the ground clearance of the bottom of the pallet, a longer slope is required to solve this problem.

[0004] When a pallet is placed on a fork and lifted by an AGV, the long slope at the top of the fork insertion end can cause the goods to tilt during transportation, thus affecting the stability of the goods transported on the pallet. Utility Model Content

[0005] The purpose of this invention is to provide a lifting and telescopic fork AGV that avoids the problem of goods tilting during transportation due to long slopes, thereby improving the stability of goods during transportation.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: a lifting and telescopic fork AGV, comprising a trolley body, a lifting device, a lifting connecting device, a telescopic device, and a fork device. The lifting device is located within the trolley body and is controlled by a transport control system. The lifting device is used to drive the lifting connecting device to lift and lower. The telescopic device is located on the lifting connecting device and is used to drive the fork device to extend and retract. The fork device includes a fork fixing frame and two sets of fork bodies. Each set of fork bodies includes a horizontal section and a sloping section. The sloping section is higher than the horizontal section. One side is close to the horizontal section, and the other side of the horizontal section is fixed to the fork holder; the sloping section is provided with a storage hole, and a mounting base is provided on the side of the storage hole close to the horizontal section. A movable support block is rotatably connected to the mounting base. The movable support block can be stored in the storage hole and its surface does not exceed the surface of the sloping section; the movable support block can be tilted up after rotation and its surface is flush with the horizontal section; the telescopic device is provided with a driving component. During the movement of the fork device on the telescopic device, the driving component will push the movable support block upward and support it.

[0007] Furthermore, the telescopic device includes a first drive assembly, a first drive rail, a second drive assembly, and a second drive rail. The first drive rail is mounted on the lifting connection device, and the second drive rail is slidably connected to the first drive rail. The first drive assembly is used to drive the second drive rail to move. The fork body is slidably connected to the second drive rail, and the second drive assembly is used to drive the fork body to move. The first drive assembly and the second drive assembly are connected to the transport control system.

[0008] Furthermore, the driving component is mounted on the second driving slide rail, and the driving component is a support wheel, which is rotatably connected to one side of the second driving slide rail.

[0009] Furthermore, the receiving hole extends through the upper side, lower side, and side away from the horizontal section of the slope section. A placement frame is provided on the side of the receiving hole away from the horizontal section. The placement frame is used to support the movable support block stored in the receiving hole. The driving component can lift the movable support block through the receiving hole.

[0010] Furthermore, the fork holder is equipped with a push rod, and the lifting connection device has a fixed seat on the side away from the fork body. The fixed seat has a through hole facing the push rod. An L-shaped hinge is rotatably connected to the fixed seat. A baffle is connected to one side of the L-shaped hinge. The push rod is used to push the other side of the L-shaped hinge to rotate. After the L-shaped hinge rotates, it can drive the baffle to rotate to a vertical state. The baffle is used to limit the position of the pallet on the fork device.

[0011] Furthermore, the fork holder is equipped with a horizontal adjustment device, and a first horizontal adjustment wheel is rotatably connected within the horizontal section of the fork body, with the upper side of the first horizontal adjustment wheel extending beyond the horizontal section; the horizontal adjustment device is used to drive the first horizontal adjustment wheel to rotate, and the rotation of the first horizontal adjustment wheel can drive the pallet loaded with goods to move in the width direction of the fork body.

[0012] Furthermore, the leveling device includes a third drive assembly, a sliding rack, a first gear component, and a second gear component. The third drive assembly is mounted on the fork holder and is used to drive the first gear component to rotate. The sliding rack has an upper gear group and a lower gear group on its upper and lower sides, respectively. The first gear component is located below the sliding rack and meshes with the lower gear group, while the second gear component is located above the sliding rack and meshes with the upper gear group. The second gear component is connected to the first leveling wheel. The third drive assembly is connected to the transport control system.

[0013] Furthermore, a second horizontal adjusting wheel is rotatably connected inside the movable support block, and the upper side of the second horizontal adjusting wheel extends beyond the movable support block; after the movable support block is rotated to the horizontal position, the heights of the first horizontal adjusting wheel and the second horizontal adjusting wheel are the same.

[0014] Furthermore, the fork holder is provided with a guide block, and a slider is provided on one side of the sliding rack. The slider is provided with a guide groove, and the guide block is slidably connected in the guide groove. The sliding direction is the length direction of the sliding rack.

[0015] Furthermore, the lifting connection device includes a lifting frame and a sliding seat. The lifting device is connected to the lifting frame, and the sliding seat is horizontally slidably connected to the lifting frame, with the sliding direction perpendicular to the extension and retraction direction of the telescopic device. A fourth drive assembly is provided on the lifting frame, which is used to drive the sliding seat to slide. The fourth drive assembly is connected to the transport control system.

[0016] The working principle of this technical solution is as follows:

[0017] The transport control system controls the lifting device to raise and lower the lifting connecting device. After raising and lowering to a suitable height, the first drive component and the second drive component respectively drive the second drive slide rail and the fork device to extend and slide, so that the fork body is inserted into the gap at the bottom of the pallet. Then, the lifting device controls the lifting connecting device to lift, thereby controlling the pallet on the fork body to rise. After reaching a suitable height, the second drive component controls the fork device to slide on the second drive slide rail and retract. During this process, the bottom of the movable support block inside the storage hole will abut against the support wheel. This allows the movable support block to rotate inside the storage hole when the fork device retracts, so that the movable support block gradually becomes parallel to the horizontal plane of the fork body, and abuts against the bottom of the pallet, providing support. This ensures that after the device lifts the pallet, it keeps it level on the fork body, preventing the goods from tilting during transportation due to a long slope, and improving the stability of the goods during transportation.

[0018] After the forks are inserted into the gap at the bottom of the pallet and the pallet is lifted, the third drive assembly drives the first gear to rotate. The first gear drives the sliding rack to move horizontally through the lower gear assembly. During the movement of the upper gear assembly on the upper side of the sliding rack, the second gear rotates. The second gear drives the first horizontal adjustment wheel to rotate, thereby horizontally adjusting the position of the pallet. When the weight on the left and right sides of the pallet is uneven, the left and right positions of the pallet on the forks can be adjusted in this way to make the weight on both sides of the pallet more balanced. This avoids unstable phenomena such as collapse due to uneven left and right positions of the pallet during transportation, and further improves the stability of goods during transportation.

[0019] In addition, the device can completely retract the fork assembly onto the second drive rail, and then the second drive rail can completely retract onto the first drive rail, reducing the footprint of the AGV. This allows the fork AGV to be converted into a lifting VGA, where goods can be placed directly on the fork body for transportation, thus improving the practicality of the device.

[0020] Simultaneously, after the fork assembly is aligned with the first drive rail, the push rod passes through the through hole on the fixed seat and abuts against the L-shaped hinge, pushing the L-shaped hinge to rotate on the fixed seat, causing the L-shaped hinge to rotate the baffle to a vertical state, so that the baffle forms a shield behind the fork assembly, providing the goods with a side support area.

[0021] The sliding connection between the sliding seat and the lifting frame allows the sliding seat to move on the lifting frame via the fourth drive component, facilitating the adjustment of the fork position after the AGV stops running.

[0022] The beneficial effects of this technical solution are as follows:

[0023] ① This technical solution, by setting up a driving component and a movable support block, can both lift the pallet by using a slope and rotate the movable support block to a horizontal position to provide horizontal support for the pallet, thus avoiding the tilting posture of goods during transportation due to a long slope and improving the stability of goods during transportation.

[0024] ② This technical solution, by setting up a horizontal adjustment device, enables the first horizontal adjustment wheel inside the fork body to rotate, thereby adjusting the left and right position of the pallet on the fork body. This balances the weight on both sides of the pallet, preventing instability such as collapse due to uneven left and right positions during transportation, and further improving the stability of goods during transport. The second horizontal adjustment wheel converts sliding friction into rolling friction when the pallet moves.

[0025] ③ In this technical solution, by setting a telescopic device, the fork assembly can be completely retracted above the trolley body, reducing the footprint of the AGV. After retraction, the fork-type AGV can be converted into a lifting VGA, allowing goods to be placed directly on the fork body for transportation, thus improving the practicality of the equipment.

[0026] ④ In this technical solution, by setting push rods, L-shaped hinges and baffles, the baffles can form a shielding plate behind the fork assembly, so that the goods have a side support area.

[0027] ⑤ In this technical solution, the sliding seat and the lifting frame are slidably connected, which facilitates the adjustment of the position of the fork device after the AGV vehicle stops running. Attached Figure Description

[0041] The basic implementation examples are as follows: Figure 1-10 As shown: Lifting and telescopic forklift AGV, such as Figure 1 , 2 As shown, the system includes a trolley body 1, a lifting device, a lifting connecting device 2, a telescopic device 3, and a fork assembly 4. The lifting device is located inside the trolley body 1 and is controlled by a transport control system. The lifting device is used to drive the lifting connecting device 2 to move up and down. Figure 3 As shown, the lifting connection device 2 includes a lifting frame 201 and a sliding seat 202. The lifting device is connected to the lifting frame 201, and the sliding seat 202 is horizontally slidably connected to the lifting frame 201, with the sliding direction perpendicular to the extension direction of the telescopic device 3.

[0042] like Figure 2 , 5As shown in Figure 6, the fork assembly 4 includes a fork holder 401 and two sets of fork bodies 402. Each set of fork bodies 402 includes a horizontal section and a sloping section. The higher side of the sloping section is closer to the horizontal section, and the other side of the horizontal section is fixed to the fork holder 401. The sloping section is provided with a storage hole 405. A mounting base 404 is provided on the side of the storage hole 405 near the horizontal section. A movable support block 403 is rotatably connected to the mounting base 404. The movable support block 403 can be stored in the storage hole 405 and its surface does not exceed the surface of the sloping section, preferably being flush with the surface of the sloping section. After rotation, the movable support block 403 can be raised, and its surface is flush with the horizontal section. The storage hole 405 extends through the upper side, lower side, and the side away from the horizontal section of the sloping section. A placement bracket 406 is provided on the side of the storage hole 405 away from the horizontal section. The placement bracket 406 is used to support the movable support block 403 stored in the storage hole 405.

[0043] like Figure 3 As shown, the telescopic device 3 includes a first drive assembly 303, a first drive slide rail 301, a second drive assembly 304, and a second drive slide rail 302. The first drive slide rail 301 is mounted on the lifting connection device 2 (specifically, the sliding seat 202). The second drive slide rail 302 is slidably connected to the first drive slide rail 301. The first drive assembly 303 drives the second drive slide rail 302 to move. The fork body 402 is slidably connected to the second drive slide rail 302. The second drive assembly 304 drives the fork body 402 to move.

During the movement of the fork device 4 on the telescopic device 3, the driving component 407 will lift and support the movable support block 403. Specifically, the driving component 407 is a support wheel, which is rotatably connected to one end of the second drive slide rail 302. There are two sets of first drive slide rails 301 and second drive slide rails 302, which correspond to two sets of fork bodies 402. The output ends of the first drive assembly 303 and the second drive assembly 304 are respectively equipped with couplings to drive the two sets of first drive slide rails 301 and the two sets of second drive slide rails 302.

[0044] like Figure 7 , 8As shown in Figure 9, a push rod 10 is provided on the fork holder 401. A fixed seat 6 is provided on the side of the lifting connection device 2 away from the fork body 402. The fixed seat 6 has a through hole 7 directly opposite the push rod 10. An L-shaped hinge 8 is rotatably connected to the fixed seat 6. A baffle 9 is connected to one side of the L-shaped hinge 8. The push rod 10 is used to push the other side of the L-shaped hinge 8 to rotate. After the L-shaped hinge 8 rotates, it can drive the baffle 9 to rotate to a vertical state. The baffle 9 is used to limit the pallet on the fork device 4. A stop block 11 is slidably connected to the push rod 10. The stop block 11 cannot pass through the through hole 7. A spring 12 is provided between the stop block 11 and the push rod 10.

[0045] like Figure 4 , 6 As shown in Figures 7, 8, and 10, a horizontal adjustment device 5 is provided on the fork holder 401. A first horizontal adjustment wheel 501 (a long, narrow wheel) is rotatably connected within the horizontal section of the fork body 402, with its upper side extending beyond the horizontal section. The horizontal adjustment device 5 drives the first horizontal adjustment wheel 501 to rotate, which in turn moves the pallet loaded with goods along the width of the fork body 402. A second horizontal adjustment wheel 502 is rotatably connected within the movable support block 403, with its upper side extending beyond the movable support block 403. When the movable support block 403 is rotated to a horizontal position, the heights of the first and second horizontal adjustment wheels 501 are the same.

[0046] The leveling device 5 includes a third drive assembly 505, a sliding rack 503, a first gear component 509, and a second gear component 504. The third drive assembly 505 is mounted on the fork holder 401 and drives the first gear component 509 to rotate. Two sets of the third drive assembly 505 and the first gear component 509 are respectively located on both sides of the fork holder 401. The sliding rack 503 has an upper gear group 508 and a lower gear group 507 on its upper and lower sides, respectively. The first gear component 509 is located below the sliding rack 503 and meshes with the lower gear group 507. The second gear component 504 is located above the sliding rack 503 and meshes with the upper gear group 508. The second gear component 504 is connected to the first leveling wheel 501. Multiple sets of the second gear component 504 and the first leveling wheel 501 can be provided. The third drive assembly 505 is connected to the transport control system and is powered by a motor. The fork holder 401 is provided with a guide block 510, and a slider 506 is provided on one side of the sliding rack 503. The slider 506 is provided with a guide groove 511. The guide block 510 is slidably connected in the guide groove 511, and the sliding direction is the length direction of the sliding rack 503.

[0047] The specific implementation process is as follows:

[0048] The transport control system controls the lifting device to raise and lower the lifting connecting device 2. After raising and lowering to a suitable height, the first drive assembly 303 and the second drive assembly 304 respectively drive the second drive slide rail 302 and the fork device 4 to slide and extend, so that the fork body 402 is inserted into the gap at the bottom of the pallet. Then, the lifting device controls the lifting connecting device 2 to lift, thereby controlling the pallet on the fork body 402 to rise. After reaching a suitable height, the second drive assembly 304 controls the fork device 4 to slide on the second drive slide rail 302 and retract. During this process, the storage hole 40... The bottom of the movable support block 403 inside the fork assembly 407 (support wheel) abuts against the drive component 407. This allows the movable support block 403 to rotate inside the storage hole 405 when the fork assembly 4 retracts, gradually making the movable support block 403 parallel to the horizontal section of the fork body 402. This allows the movable support block 403 to abut against the bottom of the pallet, providing support and ensuring that the pallet remains level on the fork body 402 after it is lifted. This prevents the goods from tilting during transportation due to a long slope, thus improving the stability of the goods during transportation.

[0049] After the fork body 402 is inserted into the gap at the bottom of the pallet and the pallet is lifted, the third drive assembly 505 drives the first gear 509 to rotate. The first gear 509 drives the sliding rack 503 to move horizontally through the lower gear assembly 507. During the movement of the upper gear assembly 508 on the upper side of the sliding rack 503, the second gear 504 will rotate. The second gear 504 drives the first horizontal adjustment wheel 501 to rotate, thereby adjusting the position of the pallet horizontally. When the weight on the left and right sides of the pallet is inconsistent, the left and right positions of the pallet on the fork body 402 can be adjusted in this way to make the weight on both sides of the pallet tend to be balanced, avoiding unstable phenomena such as collapse due to the uneven left and right positions of the pallet during transportation, and further improving the stability of goods during transportation.

[0050] In addition, the device can completely retract the fork assembly 4 onto the second drive rail 302, and then the second drive rail 302 can be completely retracted onto the first drive rail 301, reducing the footprint of the AGV. This allows the fork AGV to be converted into a lifting VGA, where goods can be placed directly on the fork body 402 for transportation, thus improving the practicality of the device.

[0051] At the same time, after the fork assembly 4 is aligned with the first drive slide rail 301, the push rod 10 will pass through the through hole 7 on the fixed seat 6 and abut against the L-shaped hinge 8, pushing the L-shaped hinge 8 to rotate on the fixed seat 6, so that the L-shaped hinge 8 drives the baffle 9 to rotate to a vertical state, so that the baffle 9 forms a shielding plate behind the fork assembly 4, giving the goods a side support area.

[0052] By sliding the sliding seat 202 and the lifting frame 201, the sliding seat 202 can be driven to move on the lifting frame 201 by the fourth drive component, which makes it easy to adjust the position of the fork device 4 after the AGV stops running.
