[0013] At the same time, by utilizing the rolling of the supporting wheels, the overall movement of the frame can be smooth, thereby facilitating the transportation of goods.

[0014] Preferably, the connecting sliding member is installed directly below the cylinder, so that the connecting sliding member can be driven to move by utilizing the extension and contraction of the cylinder output end. Two support wheels are provided, and the two support wheels are symmetrically arranged along the swing plate.

[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, and has the following beneficial effects:

[0026] 1. The anti-dumping cargo loading AGV navigation vehicle utilizes the extension of the output end of the hydraulic cylinder and the rotation connection between the hydraulic cylinder and the U-shaped frame, so that the hydraulic cylinder can adjust the angle as it rotates, and as the output end of the hydraulic cylinder continues to extend, the swing plate can be pushed to rotate and adjust the angle, and then the support assembly is driven to rotate, and the position of the support assembly is adjusted, so as to facilitate the support of the entire frame, which is helpful for subsequent anti-dumping.

[0027] Second, 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 supporting wheel will move with the right-angle connecting rod, and the bottom of the supporting wheel will contact the slope surface to increase the supporting points, thereby making it difficult for the frame to dump as a whole. At the same time, the rolling of the supporting wheel can make the frame move smoothly as a whole, thereby promoting the transportation of goods.

[0028] 3. When the anti-dumping cargo loading AGV navigation vehicle is pushed and rotated to adjust the angle 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 can use 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 the flexible gasket is used to contact the cargo on the top of the workbench, thereby achieving flexible contact, which is not easy to cause 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 easy to fall 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 can drive the support column to rotate by outputting power through the output end of the servo motor, and the workbench is driven to rotate smoothly under the rolling support of the rolling ball. 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 the 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, under the sliding support of the guide rod, allows two symmetrical crescent blocks to be stuck on the surface of the support column to support the support column, thereby allowing the support column to rotate smoothly and not easily skewed. At the same time, when the support column stops rotating, the semicircular protrusion block will be stuck in the circular groove to increase the contact area, thereby clamping the support column, making the support column less likely to be affected by external force and vibration and shake.

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, adjusting the position of the support assembly 64, thereby facilitating the support of the frame 1 as a whole, and facilitating subsequent anti-dumping.

The connecting slide 643 is slidably matched 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 fixedly installed through a pin shaft. Equipped with a support wheel 645, when the output end of the hydraulic cylinder 62 is extended to push the swing plate 63 to adjust the angle, the support wheel 645 is driven to pass through the rectangular notch 2, so that the support wheel 645 is outside the frame 1, and the staff turns on the cylinder 641 to work, and utilizes 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, and the support wheel 645 will move with the right-angle connecting rod 644, and utilize the bottom of the support wheel 645 to contact the slope surface, thereby increasing the support points, and making it difficult for the frame 1 as a whole to tip over;

The two symmetrical support wheels 645 are in contact with the slope together, making the support more stable.

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

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

[0056] A cargo loading mechanism 7, which is used to load cargo and perform steering adjustments, and is mounted on the top of the vehicle frame 1;

[0057] Among them, the cargo loading mechanism 7 includes a transmission 71 and a support column 72, the transmission 71 is installed on the top of the driver 4, the bottom of the support column 72 is rotatably connected to the middle of the top of the driver 4, a servo motor 73 is installed on the side of the outer side of the transmission 71, the output end of the servo motor 73 is connected to the support column 72 through the transmission 71, the top of the support column 72 is fixedly connected to a workbench 74, 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, a rolling ball 77 is installed at the bottom of the workbench 74 through a base, and 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, so that the structure is self-locking, 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 vehicle 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 together with the swing plate 63, so that the ball head clamping rod 65 is separated 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 state, the staff turns on 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 the goods.

[0063] The fixing assembly 76 includes an electric telescopic rod 761 and a hollow clamping piece 762. The middle of the electric telescopic rod 761 is installed on the top of the workbench 74 through a rotating seat, and the side of the bottom of the hollow clamping piece 762 is installed on the top of the workbench 74 through a rotating seat.

The inner rotation of the hollow clamping piece 762 is connected with a pressing wheel 763, and the middle of the outer side of the pressing wheel 763 is fixedly connected with a flexible gasket 764. The staff puts the goods to be transported on the top of the workbench 74 and turns on the electric telescopic rod 761 to work.

The material of the flexible gasket 764 is set to rubber material, so that flexible contact is achieved, which 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 are not easy to fall 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 Figure 6-Figure 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 at 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 outside the arc-shaped pressing plate 84 is fixedly connected with 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 outside 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, 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 skewing.

[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 run 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 control the driver 4 to make the wheel 5 rotate, thereby driving the frame 1 to move as a whole and transporting the goods. When encountering a slope, the staff turns on 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 turns on the cylinder 641 to work, and uses the extension of the output end of the cylinder 641. 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 supporting wheel 645 contacts the slope surface, thereby increasing the supporting points, making it difficult for the frame 1 to tip over as a whole. 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 supporting wheel 645 can make the frame 1 move smoothly as a whole, thereby facilitating the transportation of goods.

[0072] When the equipment has walked on the slope, the support wheel 645 can be pulled upward by contracting the air cylinder 641, and the contraction of the hydraulic cylinder 62 can drive the reverse rotation, so that the support assembly 64 is located inside the frame 1 as a whole, and the support assembly 64 is contracted and hidden. At the same time, the ball head clamping rod 65 will rotate in the reverse direction with the swing plate 63, so that the ball head clamping rod 65 is disengaged from the clamping interface 75, and the self-locking is released;

[0073] 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 state, the staff turns on 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 the goods.
