A limiting plate 16 is fixedly connected to one side of the transport plate 12. The installed limiting plate 16 can prevent the steel pipes from sliding off the transport plate 12.

[0033] Refer to Figure 1 and Figure 2 , the inner wall of the bearing box 3 is fixedly connected with a slide plate 4. The bottom of the bearing box 3 is rotatably connected with a connecting rod 5. One end of the outer ring of the connecting rod 5 is fixedly connected with a baffle 6. Both sides of the baffle 6 are fixedly connected with connecting blocks 7. The tops of the connecting blocks 7 are fixedly connected with tension springs 8. The other ends of the tension springs 8 are fixedly connected with fixed blocks 9, and the fixed blocks 9 are fixedly connected with the bearing box 3. One end of the baffle 6 is fixedly connected with uniformly distributed connecting plates 10. Through the linkage between the slide plate 4, the connecting rod 5, the baffle 6, the connecting block 7, the tension spring 8, the fixed block 9 and the connecting plate 10, combined with the first push rod motor 11, the steel pipes in the bearing box 3 can be sequentially slid onto the transport plate 12, so that only one steel pipe can be discharged each time, which helps to improve the loading accuracy, avoid process problems caused by insufficient or excessive steel pipe quantity in subsequent operations, and improve production efficiency and stability.

[0034] Refer to Figure 1and Figure 3 The output end of the first push rod motor 11 is rotatably connected to a transport plate 12. On one side of the top of the transport plate 12, a fixing assembly is provided. The fixing assembly includes rotating beads 13, which are evenly distributed on one side of the top of the transport plate 12 and are rotatably connected. At both ends of one side of the bottom of the transport plate 12, second push rod motors 14 are fixedly connected. The output ends of the second push rod motors 14 penetrate through the transport plate 12 and are fixedly connected to a main board 15. On one side of the main board 15, a servo motor 17 is fixedly connected. The output end of the servo motor 17 penetrates through the main board 15 and is fixedly connected to a bidirectional threaded rod 18, and the bidirectional threaded rod 18 is rotatably connected to the main board 15. The outer ring of the bidirectional threaded rod 18 is threadedly connected to a nut pair 19, and the nut pair 19 is slidably connected to the main board 15.

[0035] Working principle: First, put the required steel pipes into the loading box 3. Then start the first push rod motor 11 to move the transport plate 12 downward, so as to contact the connecting plate 10. Then rotate the loading box 3 through the connecting rod 5, so as to rotate the baffle 6, so that the steel pipes slide out of the loading box 3 onto the transport plate 12. Then move the transport plate 12 upward. Then, through the pulling force of the tension spring 8 on the connecting block 7, rotate the baffle 6 back to its original position. Then, during the upward movement of the transport plate 12, start the servo motor 17 to rotate the bidirectional threaded rod 18 to make the nut pairs 19 move away from or close to each other, and at the same time start the second push rod motor 14 to move the main board 15 close to the transport plate 12, so as to make the clamping plates 20 close to the steel pipes. Then make the sliding rods 21 contact and clamp the steel pipes. Then make the rising heights of the two first push rod motors 11 different, so as to make the transport plate 12 rotate by a specified angle. Then, through the rotation of the sliding rods 21 and the rotating beads 13 and the automatic weight of the steel pipes, move the steel pipes to the specified position.
