[0026] To solve the technical problems in the background art, as shown in Figs. 1-2 The present application provides a technical solution: a rotating support structure for the coating operation of the stainless steel pipe, characterized by:

[0027] The base 1 is a rectangular platform, and a sliding groove 2 is arranged on the base 1. The sliding groove 2 is a linear groove and extends along the length direction of the base 1. The cross-sectional shape of the sliding groove 2 is trapezoidal, which is matched with the protrusion at the bottom of the sliding block 3 to realize the sliding of the sliding block 3 on the base 1. The lower part of the base 1 is fixed on the ground or a workbench through foundation bolts to ensure the stability of the whole device. The sliding block 3 is slidably connected to the base 1, and the bottom of the sliding block 3 is provided with a protrusion 4 matched with the sliding groove 2. The protrusion 4 is an inverted trapezoid and can freely slide in the sliding groove 2. A threaded hole parallel to the sliding groove 2 is further arranged in the sliding block 3 and used to be threadedly connected with a first lead screw 5. One end of the first lead screw 5 is connected with a support 6 fixed to the base 1. The first lead screw 5 is a driving component, and rotating the first lead screw 5 can adjust the position of the sliding block 3, thereby adjusting the rotation radius of the pipe. A fixing seat 7 is arranged on the sliding block 3. The fixing seat 7 is L-shaped, and the bottom wall thereof is fixed to the sliding block 3, and the side wall is provided with a bearing seat 8. The fixing seat 7 is used to mount a rotating shaft 9 and a gear 10, and realizes the support and anti-skid function of the pipe through an anti-skid sleeve 11, thereby ensuring the stability of the pipe during rotation. The bearing seat 8 is provided with the rotating shaft 9, one end of the rotating shaft 9 is connected with the gear 10, and the other end is sleeved with the anti-skid sleeve 11. Two fixing blocks 12 are oppositely arranged on the side wall of the sliding block 3, and the bearing seat 6 is arranged in the fixing blocks 12. A second lead screw 13 is arranged in the fixing blocks 12 and connected with the bearing seat 6 in the fixing blocks 12. The bearing seat 6 is fixed in the fixing blocks 12 by bolts and used to support the second lead screw 13. The second lead screw 13 is provided with a connecting block 14, and the connecting block 14 is provided with a ball nut matched with the second lead screw 13. The ball nut and the second lead screw 13 are in rolling friction through balls, thereby reducing the friction resistance and improving the transmission efficiency. A rack 15 is arranged on the fixing seat 7 and fixedly connected with the connecting block 14. The rack 15 is engaged with the gear 10, and under the action of the second lead screw 13, the connecting block 14 drives the rack 15 to move along the axial direction of the second lead screw 13. The gear 10 rotates under the meshing action of the rack 15, thereby driving the pipe on the rotating shaft 9 to rotate synchronously, and realizing the rotation of the pipe during the coating operation.

[0028] It should be noted that two sliding blocks 3 are arranged along the sliding groove 2, and the two sliding blocks 3 are respectively connected to the two sides of the support 6 through the first lead screw 5. Specifically, each sliding block 3 is slidably connected with the base 1, and the bottom of the sliding block 3 is provided with a protrusion 4 matched with the sliding groove 2, and the protrusion 4 can slide in the sliding groove 2. Each sliding block 3 is further provided with a threaded hole parallel to the sliding groove 2 and used to be threadedly connected with the first lead screw 5. Each sliding block 3 is provided with an independent first lead screw 5, and each sliding block 3 is provided with a complete set of devices for rotating and supporting the pipe, which can simultaneously operate on two pipes and improve the operation efficiency.

[0029] It is worth noting that the fixed sheet 16 is provided with a screw rod, and the end of the rotating shaft 9 is provided with an internal threaded hole. The fixed sheet 16 is threadedly connected with the rotating shaft 9. Specifically, the fixed sheet 16 is a circular or square metal sheet, which is processed with a screw rod. The thread of the screw rod matches the internal threaded hole at the end of the rotating shaft 9. By screwing the screw rod into the internal threaded hole, the fixed sheet 16 can be fixed on the rotating shaft 9. The shape and size of the fixed sheet 16 can be designed according to actual needs to adapt to different specifications of the pipe. The fixed sheet 16 is fixed on the rotating shaft 9 by thread connection, which can firmly support the pipe and prevent the pipe from shaking or deviating during rotation, thereby improving the coating quality and work efficiency.

[0030] It should be noted that the diameter of the fixed sheet 16 is greater than the outer diameter of the rotating shaft 9. This design allows the fixed sheet 16 to form a larger support surface at the end of the rotating shaft 9, thereby better fixing and supporting the pipe and preventing the pipe from shaking or deviating during rotation, thereby improving the coating quality and work efficiency.

[0031] It is worth noting that the anti-skid sleeve 11 is a conical sleeve with a smaller diameter at one end near the end of the rotating shaft 9 and a larger diameter at the other end. This conical structure can be manufactured by injection molding or mechanical processing. The inner hole of the anti-skid sleeve 11 matches the outer diameter of the rotating shaft 9, which can be fixed by setting and gluing; or by setting an internal thread in the anti-skid sleeve 11 and an external thread on the rotating shaft 9 for thread connection and fixation. Since the anti-skid sleeve 11 has a smaller diameter near the end of the rotating shaft 9 and a larger diameter at the other end, this conical structure forms a guide surface and a fastening structure, which can better adapt to the shape and size of the pipe.

[0032] It should be noted that the anti-skid sleeve 11 is provided with a plurality of stepped anti-skid structures. This design can effectively increase the friction between the anti-skid sleeve 11 and the pipe, preventing the pipe from slipping during rotation, thereby improving the coating quality and work efficiency. The stepped anti-skid structure is composed of a plurality of steps, each step having different height and width, forming a stepped outer shape. This structure can increase the contact area between the anti-skid sleeve 11 and the pipe, thereby increasing the friction. The plurality of stepped anti-skid structures can be arranged along the axial direction of the anti-skid sleeve 11.

[0033] It is worth noting that the mounting holes 17 are arranged on the base 1, and the mounting holes 17 are evenly distributed around the base 1. This design enables the entire device to be stably installed on the ground or other support platform, ensuring the stability of the device during the coating operation. The mounting holes 17 can be circular, square or other suitable shapes, and the size and number can be designed according to the size of the base 1 and the actual installation requirements. Generally, the number of mounting holes 17 is 4 or more, evenly distributed around the base 1, so as to fix the base 1 on the ground or other support platform by anchor bolts or other fasteners.

[0034] While the embodiments of the present application have been shown and described, it is to be understood that the embodiments can be varied, modified, replaced and changed in many ways without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
