[0015] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] refer to Figure 1-4A pipeline high-temperature reflective layer construction device includes a fixed frame 1, a transverse moving structure 2, a hollow rotating structure 3, a high-temperature reflective structure 4, and an adjusting structure 5. The fixed frame 1 serves as the equipment's support foundation and can be constructed from channel steel welded into a rectangular frame. The bottom can be equipped with casters with brakes (not shown in the figure), allowing it to move parallel to the pipeline. The transverse moving structure 2 is mounted on the fixed frame 1, enabling the device to be positioned along the pipeline's axial direction. The hollow rotating structure 3 is mounted on the transverse moving structure 2 and coaxially fitted onto the pipeline, driving the high-temperature reflective structure 4 to rotate circumferentially around the pipeline. The high-temperature reflective structure 4 is rotatably housed within the hollow rotating structure 3 and can rotate around the central axis of the pipeline, enabling the application of reflective materials. This achieves automated construction of the high-temperature reflective layer on the pipeline, solving the problems of low efficiency and poor quality associated with manual installation.

[0017] In some embodiments, the transverse structure 2 includes a transverse motor 21, a transverse screw 22, a first fixed plate 23, a second fixed plate 24, a transverse block 25, and two limit rods 26. The transverse motor 21 can be a servo motor (model 110AEA12025-SH3, power 1.5kW), which can be fixed to the crossbeam on one side of the fixed frame 1 by motor mount bolts. The transverse screw 22 can be a trapezoidal threaded screw, which can be coaxially connected to the output shaft of the transverse motor 21 by a flexible coupling. The first fixed plate 23 and the second fixed plate 24 can both be steel plates, which are respectively vertically welded to both sides of the fixed frame 1. The first fixed plate 23 can have a through hole in its center, allowing passage. The copper sleeve and the transverse screw 22 are fitted with a clearance fit. A deep groove ball bearing can be embedded in the center of the second fixed plate 24. The end of the transverse screw 22 away from the transverse motor 21 can be rotatably connected to the second fixed plate 24 through the inner ring of the bearing. The transverse block 25 can be a cast steel part, which can be slidably disposed between the first fixed plate 23 and the second fixed plate 24. A threaded hole matching the transverse screw 22 is opened in the center of the block. The top plane is fixed to the hollow rotating structure 3 by bolts. The two limiting rods 26 can be steel optical shafts, which are symmetrically disposed on both sides of the transverse screw 22. The two ends are welded and fixed to the first fixed plate 23 and the second fixed plate 24 respectively, and pass through the guide hole of the transverse block 25 to form a double-axis guide.

[0018] In some embodiments, the hollow rotating structure 3 includes a drive motor 31, a drive shaft 32, and two rotating units. The drive motor 31 may be a stepper motor (model 57HS22, torque 2.2 N·m), which can be fixed to one side of the top of the transverse block 25 by an L-shaped bracket bolt. The drive shaft 32 may be a steel stepped shaft, one end of which can be connected to the output shaft of the drive motor 31 by a rigid coupling, and the other end can be mounted on the top of the transverse block 25 by a bearing seat. The two rotating units are symmetrically arranged on both sides of the top of the transverse block 25 and are connected to the drive shaft 32 for transmission. A rotatable high-temperature reflective structure 4 is provided between the opposite sides of the two rotating units.

[0019] In some embodiments, the rotating unit includes a fixed ring 33, multiple rotating wheels 34, a rotating ring 35, multiple limiting posts 36, and a drive assembly. The fixed ring 33 may be a 304 stainless steel ring, which can be welded and fixed to the top of the transverse block 25. The rotating wheels 34 may be polyurethane rollers, which can be installed on the side of the fixed ring 33 at equal intervals through pins. There are at least three rotating wheels 34, which cooperate with the fixed ring 33 to form a placement space for the rotating ring 35. The rotating ring 35 may be a 304 stainless steel ring, with its outer circle rolling contact with the rotating wheels 34 and its inner circle coaxial with the pipe. The limiting posts 36 may be cylindrical pins, which can be coaxially welded to the top of the rotating wheels 34. The diameter of the limiting posts 36 is larger than the diameter of the rotating wheels 34, forming an axial limit to confine the rotating ring 35 between the multiple rotating wheels 34, preventing axial displacement of the rotating ring 35 during rotation, thereby affecting the rotation effect. The drive assembly is located between the drive shaft 32 and the rotating ring 35 and is used to transmit rotational power.

[0020] In some embodiments, the drive assembly includes a drive gear 37 and an external gear ring 38. The drive gear 37 may be a spur gear, which can be coaxially mounted on the drive shaft 32 via a flat key. The external gear ring 38 may be a spur gear ring adapted to the drive gear 37, which can be fixed by welding to one side of the rotating ring 35. The external gear ring 38 meshes with the drive gear 37 to achieve power transmission.

[0021] In some embodiments, the high-temperature reflective structure 4 includes two fixed shafts 41, a rotating shaft 42, and a high-temperature reflective roll. The two fixed shafts 41 can be 304 stainless steel shafts, which are respectively welded to two external gear rings 38 on one side close to each other. The rotating shaft 42 can be a hollow steel pipe, with both ends hinged to the two fixed shafts 41, which can realize the swing between the rotating shaft 42 and the fixed shafts 41. The high-temperature reflective roll can be a special high-purity high-reflective aluminum foil roll, which can be connected to the rotating shaft 42 through a deep groove ball bearing, so as to realize the free rotation of the high-temperature reflective roll on the rotating shaft 42.

[0022] In some embodiments, an adjustment structure 5 is also included. The adjustment structure 5 is disposed between the hollow rotating structure 3 and the high-temperature reflective structure 4, and can adjust the tilt angle of the high-temperature reflective structure 4, thereby adjusting the bonding pressure and bonding tilt angle of the high-temperature reflective structure 4.

[0023] In some embodiments, the adjustment structure 5 includes an adjustment ring groove 51, an adjustment block 52, an adjustment square groove 53, a square rod 54, and an adjustment spring 55. Two adjustment ring grooves 51 are respectively opened on the sides of two external gear rings 38 that are close to each other. The cross-section of the adjustment ring groove 51 can be T-shaped. The adjustment block 52 can be a slider with a T-shaped cross-section, which can slide within the adjustment ring groove 51 and can be detachably connected to the adjustment ring groove 51 by bolts. A fixed shaft 41 is welded to the center of the adjustment block 52. The adjustment square groove 53 is opened at the axial positions of both ends of the rotating shaft 42 and can be a square blind hole. The square rod 54 can be a steel square bar, which is clearance-fitted with the adjustment square groove 53. Its outer end can be connected to the fixed shaft 41 through a ball joint bearing (model S10T). The adjustment spring 55 can be a cylindrical helical spring, with both ends connected to the end face of the square rod 54 and the inner wall of the adjustment square groove 53, respectively. The square rod 54 can prevent mutual rotation with the adjustment square groove 53, thereby ensuring that the rotation direction of the high-temperature reflective roll is consistent with the circumferential direction of the pipe and preventing distortion of the high-temperature reflective material. The cross-section of the square rod 54 can be T-shaped, and the cross-section of the adjusting square groove 53 can be convex-shaped to fit the square rod 54, which can limit the sliding of the square rod 54 in the adjusting square groove 53 and prevent the square rod 54 from disengaging from the adjusting square groove 53. The position of the square rod 54 in the adjusting square groove 53 can be adjusted by adjusting the spring 55, thereby adjusting the distance between the two adjusting blocks 52 to achieve the tilt angle of the high-temperature reflective structure 4 between the two rotating rings 35, so as to adapt to different construction requirements.

[0024] The specific working principle is as follows: The mounting bracket 1 is moved to the pipe to be constructed using the universal casters with brakes at the bottom. The pipe to be constructed is coaxially inserted into the two rotating rings 35, ensuring that the rotating rings 35 are coaxial with the pipe, and the brake fixing position is locked. The high-temperature reflective roll is installed on the rotating shaft 42, and the free end of the high-temperature reflective roll is brought into contact with the pipe surface and wound around it, initially fixing it to the pipe surface.

[0025] The transverse motor 21 drives the transverse screw 22 to rotate, and the rotational motion is converted into the linear motion of the transverse block 25 by the screw transmission, so that the transverse block 25 translates along the axial direction of the pipe.

[0026] Simultaneously, the drive motor 31 drives the drive shaft 32 to rotate, which in turn drives the drive gear 37 to rotate. Through the meshing of the drive gear 37 and the external gear ring 38, the rotating ring 35 is driven to rotate. The outer circle of the rotating ring 35 rolls in contact with multiple rotating wheels 34, and the limiting post 36 restricts its axial displacement, ensuring that the rotation trajectory is coaxial with the pipeline. The high-temperature reflective roll rotates around the pipeline under the drive of the rotating ring 35, and simultaneously feeds axially with the transverse structure 2, forming a spiral motion trajectory. The reflective material on the high-temperature reflective roll, such as aluminum foil, is continuously pressed onto the pipeline surface, realizing the automatic construction of the high-temperature reflective layer of the pipeline. The rotation speed of the rotating ring 35 is linked with the axial feed speed of the transverse block 25 (e.g., 1 r / min rotation combined with 1 m / min feed to form a spiral trajectory with a pitch of 1 m), ensuring that the overlap width of the reflective layer is uniform. When the transverse structure 2 is observed to have moved to the end of the pipeline or the preset construction length, the transverse motor 21 and the drive motor 31 simultaneously decelerate and stop. The reflective material is manually cut and the end is fixed, completing the construction of the reflective layer of a section of the pipeline. The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
