DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Embodiment: This embodiment discloses a large-caliber high-precision thick-wall seamless steel pipe production transit and transportation device, such as Figure 1-Figure 6As shown, it includes a transfer frame 1, and wheels are installed at the bottom of the transfer frame 1; a truss 4 is fixedly connected to the transfer frame 1, and a pair of rotating shafts 5 are rotatably connected to the truss 4, and the rotating shafts 5 are arranged on both sides of the truss 4, and the two ends of the rotating shafts 5 are connected to support mechanisms 2, and the support mechanisms 2 are installed on the truss 4; seamless steel pipes are placed on two support mechanisms 2 on the same side of the truss 4; wherein, a pair of transition mechanisms 3 are installed at both ends of the truss 4, which are used to transport the seamless steel pipes from the support mechanism 2 on one side to the support mechanism 2 on the other side, so that the seamless steel pipes only need to be loaded and unloaded from one side of the truss, and there is no need to adjust the direction of the transfer frame during loading and unloading.

[0025] like Figure 3 As shown, the support mechanism 2 includes a conveying frame 21, which is fixedly connected to the truss 4 at an angle, and a support leg 9 fixedly connected to the lower end of the conveying frame 21 is fixedly connected to the transfer chassis 1. The conveying frame 21 is in a long strip shape with two circular ends. A pair of first conveying wheels 22 are rotatably connected to the two ends of the conveying frame 21, and the two first conveying wheels 22 are connected by a first conveyor belt 23 for transmission, and the rotating shaft 5 is coaxially fixedly connected to the first conveying wheel 22 at the upper end of the conveying frame 21. When the rotating shaft 5 rotates, it can drive the first conveying wheel 22 and the first conveyor belt 23 to move; the conveying frame 21 is slidably connected to a support frame 25 for supporting the seamless steel pipe, and the support frame 25 is fixedly connected to the first conveyor belt 23. When the first conveyor belt 23 rotates, it can drive the support frame 25 to slide on the conveying frame 21, thereby changing the height of the conveying frame 21 and facilitating the loading and unloading of the seamless steel pipe.

[0026] A chute 26 having the same running track as the first conveyor belt 23 is provided on the circumference of the conveyor frame 21, and the support frame 25 is slidably connected to the chute 26. The support frame 25 is slidably connected to the chute 26, and the conveyor frame 21 supports the support frame 25, thereby reducing the pressure of the seamless steel pipe on the first conveyor belt 23; wherein, the chute 26 has a T-shaped cross-section, and a sliding shaft 251 slidably connected to the chute 26 is fixedly connected to the support frame 25, and a limit block 252 is fixedly connected to the sliding shaft 251, and the limit block 252 is arranged in the chute 26, so that the support frame 25 can slide along the circumference of the conveyor frame 21.

[0027] A driving motor 6 corresponding to the rotating shaft 5 is fixedly installed on the truss 4, and a worm 7 is connected to the driving motor 6. A worm wheel 8 meshing with the worm 7 is fixedly connected to the rotating shaft 5. The driving motor 6 drives the worm 7 to rotate, and the worm 7 drives the worm wheel 8 to rotate, thereby driving the rotating shaft 5 to rotate. The two driving motors 6 can independently control the rotation of the two rotating shafts 5, thereby controlling the operation of the two supporting mechanisms 2 on the same side of the truss 4, which is convenient for loading and unloading of seamless steel pipes. The structure of the worm 7 and the worm wheel 8 can lock the rotating shaft 5 to prevent the rotating shaft 5 from rotating in the opposite direction.

[0028] like Figure 5-Figure 6As shown, the transition mechanism 3 is arranged at the middle position of the upper ends of the two supporting mechanisms 2, and the transition mechanism 3 includes a fixed frame 31 and a guide frame 32. The fixed frame 31 is fixedly connected to the truss 4, and the guide frame 32 is rotatably connected to the fixed frame 31. A pair of second conveying wheels 33 are rotatably connected at both ends of the guide frame 32. The two second conveying wheels 33 are connected by a second conveyor belt 34. The guide frame 32 is rotatably connected to the fixed frame 31, and a pair of brackets 35 are fixedly connected at both sides of the fixed frame 31. A slider 36 is slidably connected to the bracket 35. A pair of guide rods 37 are fixedly connected to the guide frame 32. The guide rods 37 are slidably connected to the slider 36, and a cylindrical spring 38 is connected to the surface of the guide rod 37. The cylindrical spring 38 supports the guide frame 32. When no force is applied, the guide frame 32 is in a horizontal state; wherein, an inner gear ring 39 is fixedly connected to the surface of the second conveying wheel 33, and the first conveying wheel 22 at the upper end of the support mechanism 2 is coaxially fixedly connected to a gear 24 capable of meshing with the inner gear ring 39, and the gear 24 is arranged at a position slightly above the center of the inner gear ring 39; when the guide frame 32 is in a horizontal state, the gear 24 is not meshed with the inner gear ring 39; and when the guide frame 32 tilts to one side, the inner gear ring 39 at one end of the guide frame 32 tilts downward is meshed with the gear 24, and the inner gear ring 39 at the other end is not meshed with the gear 24; thereby, when the support mechanism 2 on one side is in operation, it can drive the transition mechanism 3 to operate, and the transition mechanism 3 will not drive the support mechanism 2 on the other side to operate, thereby avoiding the position of the support frame 25 on the support mechanism 2 on the other side from moving, resulting in the inability to receive the seamless steel pipe.

[0029] During specific implementation: when loading the seamless steel pipe, the production line directly transports the seamless steel pipe to the uppermost support frame 25 of the support mechanism 2, and then controls the movement of the support mechanism 2 through the driving motor 6, and the support mechanism 2 drives the seamless steel pipe to move to the lower side position, so that the steel pipe is installed on the support mechanism 2 from top to bottom in sequence, so that the loading height of the steel pipe is flush with the height of the production line, which is convenient for loading and unloading the seamless steel pipe; when it is necessary to move the seamless steel pipe on the left side of the truss 4 to the right side, the support mechanism 2 on the left side is controlled to operate, the support mechanism 2 on the right side remains stationary, and the support frame 25 on the right side support mechanism 2 is adjusted to a suitable height, and the first conveyor belt 23 on the left side support mechanism 2 drives the seamless steel pipe to move upward, and under the support of the support frame 25, the seamless steel pipe moves to the left side of the transition mechanism 3. Due to the gravity of the seamless steel pipe, the guide The left side of the guide frame 32 is tilted downward, so that the left inner gear ring 39 is meshed with the left gear 24. The rotation of the gear 24 drives the left inner gear ring 39 to rotate, and then drives the second conveyor belt 34 and the second conveyor wheel 33 to rotate, moving the seamless steel pipe from the left side of the second conveyor belt 34 to the middle position, and the support frame 25 is separated from the seamless steel pipe. The seamless steel pipe continues to roll to the right under inertia, driving the guide frame 32 to tilt to the right, and the seamless steel pipe rolls from the right side of the second conveyor belt 34 to the support mechanism 2 on the right side of the truss 4 under gravity; when loading and unloading the seamless steel pipe, this embodiment can keep the loading and unloading height flush with the production line height, which facilitates the loading and unloading of the steel pipe, and when loading and unloading on both sides of the truss 4, there is no need to adjust the position of the transfer frame. Through the cooperation of the transition mechanism 3 and the support mechanism 2, the seamless steel pipe can be moved from one side of the truss 4 to the other side, which is convenient for loading and unloading.
