[0024] Preferably, the elastic support block is made of rubber.

[0025] The present invention provides a cargo-loading AGV navigation vehicle that can prevent tipping, which has the following beneficial effects:

[0026] 1. This anti-dumping cargo loading AGV navigation vehicle utilizes the extension of the hydraulic cylinder output end and the rotational connection between the hydraulic cylinder and the U-shaped frame, so that the hydraulic cylinder can adjust the angle as it rotates. As the output end of the hydraulic cylinder continues to extend, the swing plate can be pushed to rotate and adjust the angle, thereby driving the support assembly to rotate and adjust the position of the support assembly, thereby facilitating the support of the entire frame and helping to prevent subsequent dumping.

[0027] 2. The anti-dumping cargo loading AGV navigation vehicle utilizes the extension of the cylinder output end and the sliding connection of the connecting sliding member to drive the right-angle connecting rod to slide downward. At this time, the support wheel will move with the right-angle connecting rod, and the bottom of the support wheel will contact the slope surface, thereby increasing the support points, making it difficult for the entire frame to dump. At the same time, the rolling of the support wheel can make the entire frame move smoothly, thereby promoting the transportation of goods.

[0028] 3. When the anti-dumping cargo loading AGV navigation vehicle is pushed to rotate and adjust the angle by using the swing plate, the ball head clamping rod is driven to rotate toward the side close to the workbench, and the ball head end of the ball head clamping rod can be clamped in the position of the clamping interface at the edge of the workbench, thereby self-locking the structure.

[0029] Fourth, the anti-dumping cargo loading AGV navigation vehicle uses the extension of the output end of the electric telescopic rod to push the hollow clamping part to rotate and adjust the angle, so that the pressing wheel is driven to run together, and uses the flexible gasket to contact the cargo on the top of the workbench, thereby achieving flexible contact and not easily causing damage to the cargo. At the same time, multiple sets of pressing wheels are used to apply clamping force to the cargo, so that the cargo can be fixed and not easily dropped during transportation.

[0030] 5. The anti-dumping cargo loading AGV navigation vehicle can pull the support wheel upward by contracting the cylinder, and can drive the reverse rotation by contracting the hydraulic cylinder, so that the support assembly is located inside the frame as a whole, and then the support assembly is contracted and hidden. At the same time, the ball head clamping rod will rotate in the opposite direction with the swing plate, so that the ball head clamping rod is disengaged from the clamping interface, thereby releasing the self-locking.

[0031] 6. The anti-dumping cargo loading AGV navigation vehicle uses the output end of the servo motor to output power, which can drive the support column to rotate, and under the rolling support of the rolling ball, the workbench is driven to rotate smoothly. At this time, the cargo on the top of the workbench will be driven to change direction, which is convenient for loading and unloading of cargo, making the overall structure more flexible to use.

[0032] 7. The anti-dumping cargo loading AGV navigation vehicle uses the elastic force provided by the elastic support block and the sliding support of the guide rod to make two symmetrical crescent blocks clamped on the surface of the support column to support the support column, thereby making the support column rotate smoothly and not prone to skewing. At the same time, when the support column stops rotating, the semicircular raised block will be clamped in the circular groove, which can increase the contact area and clamp the support column, making the support column less susceptible to shaking due to external force and vibration.

[0046] The first embodiment, as Figure 1-Figure 5 As shown, the present invention provides a technical solution: an anti-dumping cargo loading AGV navigation vehicle, comprising:

[0047] The frame 1 has a frame body that supports the mechanism. A rectangular notch 2 is opened at the bottom of both sides of the frame 1. An annular groove 3 is opened in the middle of the top of the frame 1. A driver 4 is installed in the middle of the interior of the frame 1. A wheel 5 is installed on the outer side of the driver 4.

[0048] An adjustment assembly 6, which is used to support the device and prevent it from tipping over. The adjustment assembly 6 is installed inside the frame 1;

[0049] The adjusting assembly 6 comprises a U-shaped frame 61 and a swing plate 63. The two ends of the U-shaped frame 61 are fixedly connected to the sides of the outer side of the driver 4. The top of the swing plate 63 is hinged to the top of the inner cavity of the vehicle frame 1. The top of the U-shaped frame 61 is rotatably connected to a hydraulic cylinder 62. The output end of the hydraulic cylinder 62 is hinged to the outer side of the swing plate 63. A support assembly 64 is installed in the middle of the outer side of the swing plate 63. A ball head clamping rod 65 is fixedly installed on the top of the swing plate 63. The staff starts the hydraulic cylinder 62 to work, and uses the extension of the output end of the hydraulic cylinder 62 and the rotation connection between the hydraulic cylinder 62 and the U-shaped frame 61 to enable the hydraulic cylinder 62 to adjust the angle as it rotates. As the output end of the hydraulic cylinder 62 continues to extend, the swing plate 63 can be pushed to rotate and adjust the angle, thereby driving the support assembly 64 to rotate, and adjusting the position of the support assembly 64, thereby facilitating the support of the frame 1 as a whole, which helps to prevent subsequent tipping.

[0050] The wheels 5 are evenly distributed on the outside of the driver 4, so that the frame 1 can be moved as a whole by the wheels 5. The wheels 5 are installed at the bottom of the driver 4, the hydraulic cylinder 62 is installed at an angle, and the swing plate 63 is installed at an angle, so that the swing plate 63 can be pushed by extending the output end of the hydraulic cylinder 62.

[0051] The support assembly 64 includes a cylinder 641 and a limiting block 642. The cylinder 641 is fixedly installed in the middle of the outer side of the swing plate 63. The limiting block 642 is fixedly connected to the side of the outer side of the swing plate 63. There are two limiting blocks 642, and the two limiting blocks 642 are symmetrically arranged along the swing plate 63. The output end of the cylinder 641 is fixedly installed with a connecting slide 643. A sliding groove is provided in the middle of the connecting slide 643. The connecting slide 643 slides and fits with the swing plate 63 through the sliding groove. A right-angle connecting rod 644 is fixedly installed on the side of the outer side of the connecting slide 643. The bottom end of the right-angle connecting rod 644 is fixed by a pin. Equipped with a support wheel 645, when the output end of the hydraulic cylinder 62 extends to push the swing plate 63 to adjust the angle, the support wheel 645 is driven to pass through the rectangular gap 2, so that the support wheel 645 is outside the frame 1, and the staff starts the cylinder 641 to work, and uses the extension of the output end of the cylinder 641 and the sliding connection of the connecting slide 643 to make the connecting slide 643 drive the right-angle connecting rod 644 to slide downward. At this time, the support wheel 645 will move together with the right-angle connecting rod 644, and use the bottom of the support wheel 645 to contact the slope surface, thereby increasing the support point, making it difficult for the frame 1 as a whole to tip over;

[0052] At the same time, the rolling of the support wheels 645 can make the entire frame 1 move smoothly, thereby facilitating the transportation of goods.

[0053] The connecting sliding member 643 is installed directly below the cylinder 641, so that the connecting sliding member 643 can be driven to move by utilizing the extension and contraction of the output end of the cylinder 641. There are two support wheels 645, and the two support wheels 645 are symmetrically arranged along the swing plate 63. The two symmetrical support wheels 645 contact the slope together, making the support more stable.

[0054] The second embodiment, as Figures 1-9 As shown, based on the first embodiment:

[0055] The anti-dumping cargo loading AGV navigation vehicle also includes:

[0056] The cargo loading mechanism 7 is used to load cargo and perform steering adjustments. The cargo loading mechanism 7 is installed on the top of the vehicle frame 1;

[0057] The top of the support column 72 is fixedly connected to the workbench 74, and a card interface 75 is provided at the edge of the outer side of the workbench 74. A fixing component 76 is installed on the top of the workbench 74, and a rolling ball 77 is installed at the bottom of the workbench 74 through the base. The bottom of the rolling ball 77 is embedded in the annular groove 3. When the swing plate 63 is pushed and rotated to adjust the angle, the ball head clamping rod 65 is driven to rotate to the side close to the workbench 74, and the ball head end of the ball head clamping rod 65 can be clamped in the position of the card interface 75 at the edge of the workbench 74, thereby self-locking the structure and making the swing plate 63 more stable as a whole.

[0058] The center of the workbench 74 coincides with the axis of the support column 72 , and the workbench 74 is installed right above the vehicle frame 1 .

[0059] The card interfaces 75 are evenly distributed at the outer edge of the workbench 74 . Three rolling balls 77 are provided, and the three rolling balls 77 are evenly distributed along the circumferential direction of the axis of the support column 72 , so as to facilitate rolling support for the workbench 74 .

[0060] The support wheel 645 can be pulled upward by contracting the air cylinder 641, and can be driven to rotate in the opposite direction by contracting the hydraulic cylinder 62, so that the support assembly 64 is entirely located inside the frame 1, thereby contracting and hiding the support assembly 64;

[0061] At the same time, the ball head clamping rod 65 will rotate in the opposite direction along with the swing plate 63, so that the ball head clamping rod 65 is disengaged from the clamping interface 75, thereby releasing the self-locking function.

[0062] When the goods are transported to the designated location and after the ball head clamping rod 65 and the clamping interface 75 are disengaged from the self-locking release, the staff starts the servo motor 73 to work, and uses the power output of the transmission 71 to the output end of the servo motor 73 to drive the support column 72 to rotate, and under the rolling support of the rolling ball 77, the workbench 74 is driven to rotate smoothly. At this time, the goods on the top of the workbench 74 will be driven to change direction, which is convenient for loading and unloading of goods.

[0063] The fixing assembly 76 includes an electric telescopic rod 761 and a hollow clamping member 762. The middle part of the electric telescopic rod 761 is installed on the top of the workbench 74 through a rotating seat, and the side part of the bottom of the hollow clamping member 762 is installed on the top of the workbench 74 through a rotating seat. The output end of the electric telescopic rod 761 is hinged to the middle part of the outer side of the hollow clamping member 762. The internal rotation of the hollow clamping member 762 is connected to the pressing wheel 763, and the middle part of the outer side of the pressing wheel 763 is fixedly connected to the flexible gasket 764. The staff places the goods to be transported on the top of the workbench 74 and turns on the electric telescopic rod 761 to work. By extending the output end of the electric telescopic rod 761, the hollow clamping member 762 can be pushed to rotate and adjust the angle, so that the pressing wheel 763 is driven to run together, and the flexible gasket 764 is used to contact the goods on the top of the workbench 74. The material of the flexible gasket 764 is set to rubber, which plays a flexible contact role and is not easy to cause damage to the goods.

[0064] At the same time, multiple sets of pressing wheels 763 are used to apply clamping force to the goods, so that the goods can be fixed and not easily dropped during transportation.

[0065] The flexible gasket 764 is evenly distributed in the middle of the outer side of the pressing wheel 763, and the material of the flexible gasket 764 is set to be rubber.

[0066] The third embodiment, as Figures 6-11 As shown, based on the second embodiment:

[0067] An auxiliary module 8 is installed at the top of the inner wall of the frame 1. The auxiliary module 8 is installed at a position close to the support column 72. The auxiliary module 8 includes a box body 81 and a circular groove 82. The top of the box body 81 is fixedly connected to the top of the inner wall of the frame 1 by bolts. The circular groove 82 is opened in the middle of the outer side of the support column 72. There are four circular grooves 82, and the four circular grooves 82 are evenly distributed along the circumferential direction of the axis of the support column 72. A circular hole is opened on the side of the outer side of the box body 81. A guide rod 83 is installed on the outer side of the box body 81 through the circular hole. The two ends of the guide rod 83 are respectively The cloth is fixedly installed with an arc-shaped pressing plate 84 and a crescent block 86. The arc-shaped concave surface on the outer side of the arc-shaped pressing plate 84 is fixedly connected to an elastic support block 85. The arc-shaped pressing plate 84 and the elastic support block 85 are both installed inside the box body 81. The arc-shaped concave surface on the outer side of the crescent block 86 is fixedly installed with a semicircular protrusion block 87. By utilizing the elastic force provided by the elastic support block 85 and under the sliding support of the guide rod 83, the two symmetrical crescent blocks 86 are stuck on the surface of the support column 72 to support the support column 72, thereby making the support column 72 rotate smoothly and not prone to skew.

[0068] At the same time, when the support column 72 stops rotating, the semicircular protrusion 87 will be locked in the circular groove 82, which can increase the contact area and lock the support column 72, thereby making the support column 72 less susceptible to external force and vibration and shaking.

[0069] The elastic support block 85 is made of rubber.

[0070] When in use, the staff first places the goods to be transported on the top of the workbench 74 and turns on the electric telescopic rod 761 to work. By extending the output end of the electric telescopic rod 761, the hollow clamping member 762 can be pushed to rotate and adjust the angle, so that the pressing wheel 763 is driven to move together, and the flexible gasket 764 is used to contact the goods on the top of the workbench 74, which is not easy to cause damage to the goods. At the same time, multiple sets of pressing wheels 763 are used to apply clamping force to the goods, so that the goods can be fixed;

[0071] The staff can make the wheels 5 rotate by controlling the driver 4, thereby driving the frame 1 as a whole to move and transport the goods. When encountering a slope, the staff starts the hydraulic cylinder 62 to work, and uses the extension of the output end of the hydraulic cylinder 62 to push the swing plate 63 to rotate and adjust the angle, thereby driving the support assembly 64 to rotate. At this time, the staff starts the cylinder 641 to work, uses the extension of the output end of the cylinder 641, and under the sliding connection of the connecting slide 643, the connecting slide 643 drives the right-angle connecting rod 644 to slide downward, and the support wheel 645 will As the right-angle connecting rod 644 moves together, the bottom of the support wheel 645 contacts the slope surface, thereby increasing the support point, making it difficult for the frame 1 as a whole to tip over. When the swing plate 63 is pushed and rotated to adjust the angle, the ball head clamping rod 65 is driven to rotate toward the side close to the workbench 74, and the ball head end of the ball head clamping rod 65 can be clamped in the position of the clamping interface 75 at the edge of the workbench 74, thereby self-locking the structure, making the swing plate 63 more stable as a whole, and the rolling of the support wheel 645 can make the frame 1 as a whole move smoothly, thereby facilitating the transportation of goods.

[0072] When the equipment has finished walking on the slope, the support wheel 645 can be pulled upward by contracting the cylinder 641, and the contraction of the hydraulic cylinder 62 can drive the reverse rotation, so that the support assembly 64 is entirely inside the frame 1, thereby shrinking and hiding the support assembly 64. At the same time, the ball head clamping rod 65 will rotate in the opposite direction along with the swing plate 63, so that the ball head clamping rod 65 is disengaged from the clamping interface 75, thereby releasing the self-locking function.

[0073] When the goods are transported to the designated location and the ball head connecting rod 65 and the card interface 75 are disengaged from the self-locking release, the staff starts the servo motor 73 to work, and uses the power output of the transmission 71 to the output end of the servo motor 73 to drive the support column 72 to rotate, and under the rolling support of the rolling ball 77, the workbench 74 is driven to rotate smoothly.
