DETAILED DESCRIPTION

[0025] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Example 1

[0027] like Figure 1 to Figure 6 As shown, this embodiment proposes an AGV intelligent transport device that can realize the anti-tilt function, including a base plate 5 and a flat plate 15. The bottom of the base plate 5 is fixedly connected with four symmetrically arranged transport wheels 14 by bolts, and the four transport wheels 14 are fixedly provided with damping shock absorbers 20. The bottom of the base plate 5 is installed with a control terminal 21. The top of the base plate 5 is welded with a pad 2, and the top of the pad 2 is installed with a first motor 3. The top of the base plate 5 is welded with two symmetrically arranged support blocks 6, and the two support blocks 6 are internally installed with a rotating shaft 7 for common rotation. The output end of the first motor 3 is coaxially fixedly connected with one end of the rotating shaft 7 through a coupling. The top of the flat plate 15 is fixed by screws. It is connected with four symmetrically arranged side baffles 4. Through the arrangement of the first connecting rod 8, the second connecting rod 9 and other structures, when the transporting device moves to the inclined slope during the transporting process, the control terminal 21 monitors the inclination of the road surface and sends a signal to the first motor 3 and the double-headed cylinder 10. The double-headed cylinder 10 pushes one of the push rods 22 and the side plate 1, and the two blocks 23 fixedly connected to the side plate 1 also move accordingly, so that the two rotating columns 12 on one side of the flat plate 15 lose their limit. Then the first motor 3 drives the first connecting rod 8 to drive the second connecting rod 9 and the flat plate 15 to rotate and tilt, so that the flat plate 15 is tilted and kept level with the ground, thereby avoiding the tilting of objects during the transporting process.

[0028] like Figure 1 to Figure 6As shown, two symmetrically arranged first connecting rods 8 are fixedly sleeved on the outer circumferential surface of the rotating shaft 7, one end of the two first connecting rods 8 is movably hinged with a second connecting rod 9, one end of the two second connecting rods 9 is commonly movably hinged with a connecting rod 24, and the connecting rod 24 is fixedly nested inside the flat plate 15, and four symmetrically arranged rotating columns 12 are welded to the bottom of the flat plate 15.

[0029] like Figure 1 to Figure 6 As shown, the top of the base plate 5 is fixedly connected to four symmetrically arranged fixed support plates 13 by screws, and the inside of the four fixed support plates 13 is provided with an arc-shaped rotation groove, the rotating column 12 and the arc-shaped rotation groove have the same shape and size, and the top of the four fixed support plates 13 is welded with a guide block 11.

[0030] like Figure 1 to Figure 6 As shown, the guide block 11 is provided with a slide groove running through it, and the insides of the four slide grooves are slidably connected with block blocks 23, and one side of each two block blocks 23 is commonly fixedly connected to the side plate 1, and a double-headed cylinder 10 is installed on the top of the bottom plate 5, and the two output ends of the double-headed cylinder 10 are fixedly connected with coaxially arranged push rods 22, and one end of the two push rods 22 is fixedly connected to one side of the two side plates 1 respectively.

[0031] In this embodiment, the object to be transported needs to be placed securely on the top of the flat plate of the device. Once the control terminal receives the transport instruction, it will immediately start and control the rotation of the four transport wheels. When the transport device encounters an inclined road or slope during its movement, the control terminal installed at the bottom of the base plate will sense the road condition in advance.

[0032] If the slope is downward, when the handling device moves to such a road surface, the control terminal will respond quickly, the double-headed cylinder will start, and push the push rod fixedly connected to the side plate on the side that is tilted downward, the push rod will drive the side plate to move, and then drive the two block blocks to move synchronously, at this time, the two block blocks will no longer block the rotating column fixedly connected to the plate on the side corresponding to the tilted side plate, thereby allowing the side plate to make necessary angle adjustments;

[0033] Next, the first motor starts, the rotating shaft and the two first connecting rods begin to swing, and the two second connecting rods movably hinged to the first connecting rods also move accordingly, pushing the connecting rod, thereby causing one side of the flat plate fixedly connected to the connecting rod to tilt upward, and this tilted side is the same side as the side plate tilted downward. It should be noted that the other side of the flat plate is blocked by two blocks, so the two rotating columns thereon can only rotate but cannot be pushed up. Therefore, the movable side will rotate with the two rotating columns that can rotate as the axis under the drive of the two second connecting rods;

[0034] When the other side of the flat plate is lifted to be parallel to the fixed side, the items on the entire flat plate will remain horizontal, ensuring that the items will not tilt during transportation, realizing the anti-tilt function of the AGV intelligent transportation device and improving the stability and safety of transportation.

[0035] When the AGV intelligent handling device encounters an uphill road surface, the same control terminal will sense the uphill trend of the road surface in advance and start the corresponding adjustment mechanism. The double-headed cylinder will push the push rod fixedly connected to the side plate on the uphill side, thereby driving the block to move so that they no longer block the rotating column fixedly connected to the side plate. Subsequently, the first motor starts, drives the shaft and the two first connecting rods to swing, and through the linkage of the second connecting rod, pushes the connecting rod to make one side of the plate fixedly connected to the connecting rod tilt upward. Since the block on the other side still plays a blocking role, the side plate can only rotate with the rotating column as the axis. Finally, when the uphill side of the plate is lifted to be parallel to the fixed side, the items on the entire plate will remain horizontal, ensuring the stability and safety of the items during the uphill process, so that the AGV intelligent handling device can flexibly respond to various road conditions and achieve efficient and safe handling tasks.

[0036] Example 2

[0037] like Figure 1 to Figure 6 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that the top of the flat plate 15 is fixedly connected with four symmetrically arranged guide bars 25 by screws, the inside of the four guide bars 25 are provided with guide grooves running through themselves, the inside of the four guide grooves are slidably connected with slide bars 27, the four slide bars 27 are commonly fixedly connected with an outer frame 26, the bottom of the outer frame 26 and the top of the flat plate 15 are commonly connected with a flexible baffle 28, through the arrangement of the second motor 16 and the double-headed screw 17 and other structures, when the transport device encounters a bumpy road during the transport process, the control terminal 21 drives the second motor 16 and the double-headed screw 17 to rotate, and the two movable blocks 19 threadedly mounted on the double-headed screw 17 move to both sides at the same time, and push the outer frame 26 upward through the push rod 18, and the outer frame 26 moves upward to pull the flexible baffle 28 for verification, thereby providing good protection for the items placed on the top of the flat plate 15.

[0038] like Figure 1 to Figure 6 As shown, one side of the flat plate 15 is fixedly connected to a horizontal plate by screws, a second motor 16 is installed on the top of the horizontal plate, and an output end of the second motor 16 is fixedly connected to a double-headed screw 17 through a coupling, and the double-headed screw 17 is rotatably installed inside two of the guide bars 25.

[0039] like Figure 1 to Figure 6As shown, two symmetrically arranged movable blocks 19 are threadedly sleeved on the double-headed screw 17, and the two movable blocks 19 are movably hinged with push rods 18. Two symmetrically arranged connecting blocks are welded to the bottom of the outer frame 26, and one end of the two push rods 18 is movably hinged to the two connecting blocks respectively.

[0040] like Figure 1 to Figure 6 As shown, the control terminal 21 is electrically connected to the first motor 3, the second motor 16, and the cylinder.

[0041] In this embodiment, when the AGV intelligent handling device travels on a bumpy road, in order to ensure that the items on the flat plate will not fall due to the bumps, the control terminal will respond quickly and drive the second motor to start. At this time, the double-headed screw begins to rotate. Since the movable block is arranged on the double-headed screw through a threaded sleeve, they will move to both sides at the same time. As the movable block moves, the two push rods that are hinged to them will move synchronously to lift the outer frame evenly and steadily.

[0042] The rising action of the outer frame benefits from four slide bars fixedly connected to it. These slide bars slide smoothly along the guide grooves opened inside the guide strips, thereby ensuring the vertical and stable lifting of the outer frame. The bottom of the outer frame is connected to a flexible baffle, and the other side of the flexible baffle is closely connected to the flat plate. Therefore, in the process of the outer frame moving upward, the flexible baffle will be pulled and unfolded, forming a tighter protective barrier. The material of the flexible baffle is a high-strength and elastic rubber material. This material not only has excellent tensile resistance, can maintain a stable shape and tension when the outer frame moves upward, but also has good flexibility and wear resistance, can adapt to different road conditions and bumps, and ensure that it is not easy to be damaged during long-term use;

[0043] It should be noted that the double-headed screw is below two of the sliding rods and will not cause motion interference. The control terminal used is the core control unit of the AGV intelligent handling device. The control terminal uses a high-performance processor and memory to ensure fast and stable execution of handling instructions and data processing tasks. At the same time, it is also equipped with a variety of sensors, inclination sensors, distance sensors and force sensors, etc., which are used to monitor the status of the handling device and the surrounding environment in real time, so as to make accurate decisions and adjustments. This product is an existing technology, an intelligent warehouse robot control terminal, model CTU-AGV5000.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
