The setting of the limit flip plate facilitates the installation of the flip bearing column on the transport bearing frame for up and down flipping, and facilitates the installation of the outer end of the flip connecting plate through the fixed shaft and connecting the flip bearing plate to realize flip support, which solves the problem that the flatbed truck is a flat structure and is easy to cause the steel bars to fall during the transportation of steel bars, and it is inconvenient to install a flip plate on the bearing frame and flip it upward to limit the position when the steel bars are transported.

[0004] However, the above-mentioned loading platform cannot limit the position of the object on the upper part of the platform when in use, so that the object is prone to tilt or offset, and the above-mentioned loading platform is not convenient to move. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4The utility model provides a technical solution: an automatic walking loading platform with a material anti-tilt structure, comprising: four groups of moving wheels 3 for driving the movement of materials, a bearing assembly 2 for driving the moving wheels 3 to rise and fall is arranged on the top of the moving wheels 3, and four groups of limiting assemblies 1 for limiting the position of materials are arranged on the top of the bearing assembly 2.

[0025] The limiting assembly 1 includes: a fixed block 13, the interior of the fixed block 13 is slidably sleeved on the outside of the two groups of guide rods 12, one end of the guide rod 12 is fixedly connected to one side of the limiting block 15, the other end of the guide rod 12 is fixedly connected to one side of the limiting plate 11, one side of the limiting plate 11 is also movably connected to one end of the screw rod 16, the other end of the screw rod 16 is fixedly connected to one side of the knob 17, and the screw rod 16 is located between the two groups of guide rods 12.

[0026] Furthermore, when in use, the material to be transported is placed on the loading platform 29, and then the knob 17 is turned clockwise. The knob 17 drives the screw rod 16 to rotate clockwise, so that the screw rod 16 moves in the direction of the limit plate 11, and pushes the limit plate 11 away from the fixed block 13, so that the four groups of limit plates 11 clamp the outside of the material, thereby limiting the material to prevent displacement during transportation and making the material move more stably.

[0027] A spring 14 is provided between the fixing block 13 and the limiting block 15 , and the inner ring of the spring 14 is slidably sleeved on the outer side of the guide rod 12 .

[0028] Furthermore, when the limit plate 11 moves away from the fixed block 13, the limit plate 11 drives the limit block 15 to move toward the fixed block 13 through the guide rod 12. When the limit block 15 moves toward the fixed block 13, the limit block 15 will compress the spring 14. To release the limit plate 11 from limiting the material, just turn the knob 17 counterclockwise, and the knob 17 drives the screw rod 16 to rotate counterclockwise, so that the screw rod 16 moves away from the limit plate 11. At this time, the spring 14 rebounds and pushes the limit block 15 away from the fixed block 13. The limit block 15 drives the limit plate 11 through the guide rod 12, so that the limit plate 11 moves toward the fixed block 13 and away from the material, thereby releasing the limit on the material. It is very convenient. Through the movement of the limit plate 11, the spacing between the four groups of limit plates 11 can be adjusted according to the external size of the material, so that the limit plate 11 can limit materials of different sizes, thereby improving the applicability of the loading platform.

[0029] The bearing assembly 2 includes: a loading platform 29, the top of which is fixedly connected to the bottom of the fixed block 13, and the four corners of the bottom of the loading platform 29 are fixedly connected to the top of the support rod 22. The bottom end of the support rod 22 is fixedly connected to the top of the pad 24, and the side of the support rod 22 is slidably inserted into the inside of the four corners of the lifting plate 23. The top of the lifting plate 23 is rotatably connected to the bottom ends of two groups of diagonal support rods 28, and the top ends of the two groups of diagonal support rods 28 are rotatably connected to the bottoms of two groups of moving blocks 26. The internal threads of the moving blocks 26 are connected to the outside of the left and right screw rods 27, and the outside ends of the left and right screw rods 27 are rotatably connected to the inside of the mounting plate 25, and the top of the mounting plate 25 is fixedly connected to the bottom of the loading platform 29. One side of the mounting plate 25 is fixedly connected to the outside of the motor 1 21, and the output shaft of the motor 1 21 is connected to one end of the left and right screw rods 27 through a coupling.

[0030] Furthermore, after the material is limited, the motor 21 is started, and the motor 21 drives the left and right rotating screws 27 to rotate counterclockwise. When the left and right rotating screws 27 rotate counterclockwise, they drive the two groups of moving blocks 26 to move away from each other. When the two groups of moving blocks 26 move away from each other, they push the lifting plate 23 downward through the diagonal support rods 28. The lifting plate 23 drives the moving wheel 3 to move downward and contact the ground, and at the same time the pad 24 rises and leaves the ground, so that the entire loading platform can move.

[0031] Furthermore, when the material is transported to the designated location, the motor 21 drives the left and right screws 27 to rotate clockwise. When the left and right screws 27 rotate clockwise, they drive the two groups of moving blocks 26 to move closer to each other. When the two groups of moving blocks 26 move closer to each other, they pull the lifting plate 23 up through the diagonal support rods 28. The lifting plate 23 drives the moving wheel 3 to rise and leave the ground. At the same time, the pad 24 contacts the ground. In this way, the entire loading platform will be unable to move, making it more stable and easier to unload.

[0032] The moving wheel 3 includes: a U-shaped plate 32, the top of the U-shaped plate 32 is fixedly connected to the bottom of the lifting plate 23, one side of the U-shaped plate 32 is fixedly connected to the outside of the second motor 33, and the output shaft of the second motor 33 is fixedly inserted into the inside of the roller 31.

[0033] Furthermore, during movement, the second motor 33 drives the roller 31 to rotate, so that the loading platform can move by itself, making it more convenient to move the loading platform, saving time and effort.

[0034] Working principle: When in use, place the material to be transported on the loading platform 29, and then turn the knob 17 clockwise. The knob 17 drives the screw 16 to rotate clockwise, so that the screw 16 moves in the direction of the limit plate 11, and pushes the limit plate 11 away from the fixed block 13, so that the four sets of limit plates 11 clamp the outside of the material, thereby limiting the material to prevent displacement during transportation, so that the material can be moved more steadily. When the limit plate 11 moves away from the fixed block 13, the limit plate 11 drives the limit block 15 to move toward the fixed block 13 through the guide rod 12. When the limit block 15 moves toward the fixed block 13, the limit block 15 will compress the spring 14. To release the limit on the material by the limit plate 11, just turn the knob 17 counterclockwise, and the knob 17 drives the screw rod 16 to rotate counterclockwise, so that the screw rod 16 moves away from the limit plate 11. At this time, the spring 14 rebounds and pushes the limit block 15 away from the fixed block 13. The limit block 15 drives the limit plate 11 through the guide rod 12, so that the limit plate 11 moves toward the fixed block 13 and away from the material at the same time, thereby releasing the limit on the material. It is very convenient. Through the movement of the limit plate 11, the spacing between the four groups of limit plates 11 can be modulated according to the external size of the material, so that the limit plate 11 can limit materials of different sizes, thereby improving the applicability of the loading platform.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
