[0034] A method for using a multi-steel pipe precision transport and feeding device includes the following steps: S1: First, select a specified number of steel pipe positioning components 14 according to the needs of steel pipe transportation. Insert the connecting plate 13 into the slot 36 on the side wall of the mounting plate 29, and insert the mounting plate 29 into the slot 36 to a specified depth according to the diameter of the steel pipe to be loaded. Then screw the bolt 38 into the mounting plate 29 so that the bolt 38 extends into the slot 36 and is threadedly connected to the threaded hole 37, thereby realizing the fixed connection between the connecting plate 13 and the mounting plate 29. S2: Repeat the operation of step S1 above to install the steel pipe positioning components 14 onto the connecting plate 13 of the connecting block 12 on the fixing block 10, forming a basic steel pipe positioning component 14 arrangement and installation operation. S3: Select the remaining connecting blocks 12 with connecting plates 13, and insert the connecting plates 13 into the slots 36 on the other side walls of the steel pipe positioning assembly 14 according to the needs of steel pipe transportation and loading. Then, use bolts 38 to fix the connecting plates 13 and the mounting plate 29. Repeat the operations in steps S1 and S2 above to realize the arrangement and installation of the steel pipe positioning assembly 14 again. S4: Repeat steps S1-S3 above until the actual required quantity and method of steel pipe transportation and loading are the same as the quantity and arrangement of steel pipe positioning components 14. Then stop the installation of steel pipe positioning components 14 and connecting blocks 12. S5: Following the steps S1-S4 above, install a device for transporting and loading steel pipes that is mirror-image of the above structure. S6: During the process of transporting and loading steel pipes, the operator controls the equipment inside the control box 2 through an external remote control device. The drive system 3 is used to move the two devices for transporting and loading steel pipes to the two sides of the steel pipe to be transported. The position of the steel pipe transporting and loading device is adjusted by the drive system 3 so that each steel pipe positioning component 14 is aligned with a steel pipe. The drive system 3 is started so that the positioning plate 32 on the steel pipe positioning component 14 is inserted into both ends of the inner cavity of the steel pipe. S7: Start the electric push rod 33. The electric push rod 33 drives the circular plate 34 to move. The circular plate 34 drives the mounting block 31 to move in the inclined groove 30 through the connecting rod 35. The mounting block 31 drives the positioning plate 32 to move at both ends of the steel pipe cavity, so that the positioning plate 32 can be clamped on the inner wall of both ends of the steel pipe, realizing the positioning and clamping operation of the steel pipe. S8: Then start the second motor 24. The second motor 24 drives the first worm 23 to mesh with the first worm wheel 22 to rotate. The first worm wheel 22 drives the second threaded rod 21 to rotate. The rotation of the second threaded rod 21 can make the movable shell 9 move up and down in the inner cavity of the fixed shell 8, so as to lift the steel pipe to a certain height. Then stop the second motor 24 from continuing to rotate, and move the steel pipe from the stack of steel pipes to one side through the drive system 3. Then start the second motor 24 again and make the second motor 24 rotate in the opposite direction to lower the center of gravity of the steel pipe being transported, improve the stability of the steel pipe during the loading and transfer process, and stop the rotation of the second motor 24. S9: After the steel pipe is transported to the designated position, the second motor 24 and the third motor 28 are started according to the height requirements of the transport vehicle. The second motor 24 drives the second threaded rod 21 to rotate through the first worm gear 23 meshing with the first worm wheel 22, so that the movable shell 9 rises to the designated height. The third motor 28 drives the third threaded rod 25 to rotate through the second worm gear 27 meshing with the second worm wheel 26, so that the fixed block 10 drives the connecting block 12 to rise to the designated height. The height of the steel pipe can be adjusted by the movement of the connecting block 12 until the steel pipe is adjusted to the appropriate height, and then the rotation of the second motor 24 and the third motor 28 is stopped. S10: The base 1 is moved to the bottom of the vehicle by the drive system 3 and the first motor 15 is started. The first motor 15 drives the first threaded rod 16 to rotate, so that the first threaded rod 16 drives the movable plate 5 to move out of the top groove 4. During the movement of the movable plate 5, the support plate 18 can be automatically unfolded under the action of the spring 20, increasing the support points and effectively improving the stability of the device. S11: When the steel pipe moves to a suitable position inside the truck bed of the transport vehicle, the first motor 15 is stopped, and the second motor 24 and the third motor 28 are started, so that the second motor 24 and the third motor 28 rotate in opposite directions, so that the steel pipe can be conveniently loaded into the transport vehicle. After the steel pipe is placed stably, the electric push rod 33 is started. The electric push rod 33 pulls the connecting rod 35 through the circular plate 34. The connecting rod 35 drives the positioning plate 32 to move towards the center of the mounting plate 29 through the mounting block 31, releasing the fixation of the steel pipe. Then, the steel pipe transport and loading device is driven by the drive system 3 to move away from the steel pipe, so that the positioning plate 32 is pulled out from the steel pipe, completing the single loading operation of the steel pipe. S12: Repeat steps S6-S11 above to achieve the transportation and loading operation of multiple steel pipes in a single operation until the transportation and loading of steel pipes is completed.
