[0002] The earliest flatbed carts can be traced back to ancient civilizations, such as carts in ancient Egypt and Rome. These carts are usually made of wood and are pushed by manpower. These early flatbed carts have simple structures and are mainly used in farmland, construction sites and markets to transport food, building materials and other items. With the advent of the Industrial Revolution and the development of steel and machinery manufacturing technology, the structure and materials of flatbed carts have been significantly improved. Iron and steel flatbed carts began to appear, and the wheels changed from wood to metal, which improved durability and carrying capacity. With the popularization of mechanized production, the design and manufacture of flatbed carts have become more standardized, and more variants have emerged, such as electric flatbed carts and folding flatbed carts with handles.

The outer diameter of the second vertical rod is larger than the inner diameter of the fixed opening. When the delivery flap 9 is kept horizontal, under the action of the rebound force of the fourth telescopic spring 39, the lower end of the second vertical rod of the limit block 13 contacts the upper end surface of the delivery flap 9, and at this time, the distance between the lower end of the second horizontal rod of the limit block 13 and the upper end surface of the delivery flap 9 is larger than the thickness of the flange 10.
[0038] like Figure 1 , 2 As shown in Figures 3, 6, 9, 10, 11, 15, and 16, a positioning groove 11 extending forward and backward is provided in the middle of the delivery flap plate 9, and the inner positioning mechanism is provided inside the positioning groove 11.

A sliding block is slidably provided inside the positioning groove 11, and the left and right outer walls of the sliding block are in sliding contact with the left and right inner walls of the positioning groove 11, and the sliding block is screwed to the outer side of the worm 24. A vertical positioning column 12 is fixedly provided on the upper end surface of the sliding block.
[0039] The present invention provides a method for using a large flange transport flatbed truck with a turning function, comprising the following steps: Step 1: When the flatbed vehicle is in the initial state, the first horizontal section of the delivery and flipping column 30 and the second horizontal section of the connecting flipping column 36 are both in a horizontal state, and the delivery and flipping plate 9 is also in a horizontal state; the second motor 37 controls the second horizontal rod of the limit block 13 to rotate to the outside of the delivery and flipping plate 9. Then the flange 10 is placed on the upper end of the delivery and flipping plate 9, and the third motor 41 is turned on. The third motor 41 drives the worm gear 42 to rotate, and the worm gear 42 drives the worm 24 to rotate. The worm 24 drives the sliding block and the positioning column 12 to slide backward inside the positioning groove 11 until the positioning column 12 contacts the inner cylindrical surface of the flange 10, and the flange 10 is pushed to slide backward on the upper end of the delivery and flipping plate 9 by the positioning column 12 until the outer cylindrical surface of the flange 10 contacts the positioning blocks 15 on the two delivery and flipping columns 30, and the position of the flange 10 is fixed by the principle of three-point clamping, thereby realizing the positioning of the flange 10 on the upper end of the delivery and flipping plate 9. Then, the two second motors 37 are controlled to start rotating, and the second motors 37 drive the limit block 13 to rotate, so that the second horizontal rod of the limit block 13 rotates to the top of the flange 10 .
[0040] Step 2, then control the first motor 31 to rotate, the first motor 31 drives the driving sprocket to rotate through the reducer 32, the driving sprocket drives the driven sprocket 34 to rotate through the chain 33, the driven sprocket 34 drives the rotating rod to rotate, the rotating rod drives the two flip rods 44 to rotate, the two flip rods 44 drive the two connecting rods 35 and the two hinged rods 45 to move, so that the connecting flip column 36 and the sending flip column 30 both rotate upward around the rotating rod, the first horizontal section of the sending flip column 30 and the second horizontal section of the connecting flip column 36 gradually approach each other, so that the sending flip plate 9 and the connecting flip plate 16 both rotate upward around the rotating rod, and the sending flip plate 9 and the connecting flip plate 16 approach each other.
[0041] When the flap-feeding plate 9 rotates upward, the flange 10 is limited by the two limit blocks 13 and will not be separated from the flap-feeding plate 9 .
[0042] During the upward rotation of the connecting flap 16, the fixed rod rotates downward, and the support box 21 rotates upward along with the connecting flap column 36, so that the two spring telescopic rods 43 are continuously stretched. Since the distance between the ends of the two spring telescopic rods 43 connected to the fixed rod remains unchanged, the two spring telescopic rods 43 drive the two moving seats 18 to continuously slide inside the sliding groove of the support box 21 and approach each other, thereby making the two support tubes 20 approach each other. When the connecting flap 16 rotates upward to the maximum angle, the distance between the two support tubes 20 is the shortest.
[0043] Step 3: After the delivery flap 9 and the connecting flap 16 rotate to the maximum angle, the delivery flap 9 rotates 93° and the connecting flap 16 rotates 87°. At this time, the upper end of the flange 10 on the delivery flap 9 tilts toward the side close to the connecting flap 16 due to the effect of gravity, and the upper end of the flange 10 contacts the second horizontal rods of the two limit blocks 13. At this time, the limit blocks 13 are driven to rotate by the second motor 37, and the second horizontal rods of the two limit blocks 13 rotate to be separated from the flange 10. At the same time, the third motor 41 is controlled to rotate in the opposite direction, so that the positioning column 12 is separated from the inner cylindrical surface of the flange 10. In this way, the flange 10 flips toward the connecting flap 16 under the effect of its own gravity until the flange 10 flips onto the connecting flap 16. In the process of the flange 10 flipping to the upper end of the connecting flap 16, the left and right rows of buffer springs 47 are compressed, thereby reducing the impact of the flange 10 on the connecting flap 16. The lower end of the flange 10 contacts the positioning blocks 15 on the two connecting columns 36, and the upper end of the flange 10 squeezes the inclined surfaces of the upper ends of the two telescopic blocks 23 during the flipping process, so that the telescopic blocks 23 retract into the telescopic groove, and the first telescopic spring is compressed until the outer cylindrical surface of the flange 10 contacts one end of the outer side of the two telescopic blocks 23, and the flange 10 is initially squeezed and limited by the rebound force of the two first telescopic springs.
[0044] Step 4, then control the first motor 31 to rotate in the opposite direction, the first motor 31 drives the driving sprocket to rotate in the opposite direction through the reducer 32, the driving sprocket drives the driven sprocket 34 to rotate in the opposite direction through the chain 33, the driven sprocket 34 drives the rotating rod to rotate in the opposite direction, the rotating rod drives the two flipping rods 44 to rotate in the opposite direction, the two flipping rods 44 drive the two connecting rods 35 and the two hinged rods 45 to move in the opposite direction, so that the connecting and flipping columns 36 and the sending and flipping columns 30 both rotate downward around the rotating rod, and the first horizontal section of the sending and flipping column 30 and the second horizontal section of the connecting and flipping column 36 gradually move away from each other until the first horizontal section of the sending and flipping column 30 and the second horizontal section of the connecting and flipping column 36 are both in contact with the support rod 4. During the downward rotation of the connecting plate 16, the fixed rod rotates upward, and the support box 21 rotates downward along with the connecting column 36, so that the two spring telescopic rods 43 are continuously shortened under the action of their own resilience. Since the distance between the two ends of the spring telescopic rods 43 connected to the fixed rod remains unchanged, the two spring telescopic rods 43 drive the two moving seats 18 to continuously slide inside the sliding groove of the support box 21 and move away from each other, thereby causing the two support tubes 20 to continuously move away from each other. When the second horizontal section of the connecting column 36 rotates downward to contact the support rod 4, the two support tubes 20 are respectively in contact with the inner cylindrical surface of the flange 10, and the flange 10 is supported by the two support tubes 20. In this way, the flange 10 is supported by the two positioning blocks 15, the two support tubes 20 with resilience, and the two telescopic blocks 23 with resilience, ensuring that the flange 10 will not shake during the later transportation process.
[0045] Step five, finally, the battery 46 inside the fixed box 29 is used to provide a power source for the entire flatbed truck, and then the driving motor 28 and the driving shaft 8 are used to rotate the roller 7 connected to one end of the driving shaft 8, and then the driving shaft 8 and the support seat 27 are used to make the flatbed truck move and transport smoothly, and then the obstacle avoidance radar 3 on the supporting frame 1 is used to prevent the flatbed truck from colliding during transportation, and then the warning light 2 can effectively remind the staff that the flatbed truck is being flipped or moved.
