Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0013] Please see Figures 1-5 This embodiment provides a boiler superheater tube anti-wear protection structure, including a connecting seat 1 and a protective tile 2. An inner positioning plate 11 is symmetrically installed on the inner side of the connecting seat 1. An adjusting screw 12 is rotatably installed on the inner side of the inner positioning plate 11 via a bearing. A connecting sleeve 13 is symmetrically screwed onto the outer wall of the adjusting screw 12. The protective tile 2 is installed on the upper surface of the connecting sleeve 13. Connecting columns 14 are symmetrically installed on the bottom of the protective tile 2. The bottom of the connecting columns 14 is installed on the upper surface of the connecting seat 1 via a sliding fit. During operation, the threads of the adjusting screw 12 are opposite in direction. Rotating the adjusting screw 12 adjusts the front and rear positions of the protective tile 2. Superheater tubes are arranged inside the protective tile 2, facilitating adjustment of the protective tile 2 according to the position of the superheater tubes. This further improves the versatility of the device and enables protection for multiple superheater tubes.

[0014] An outer frame 15 is arranged on the outer end of the connecting seat 1. Damping spring shock absorbers 16 are symmetrically installed at the bottom of the outer frame 15. A connecting seat 1 is installed on the upper surface of the damping spring shock absorber 16. Cotton pads 17 are symmetrically installed on the top of the connecting seat 1. Multiple first screw holes 18 are opened at the bottom of the outer frame 15. During operation, the damping spring shock absorber 16 provides shock absorption and protection for the protective tile 2, and the cotton pads 17 provide shock absorption and protection for the upper end of the connecting seat 1, so as to prevent the device from being damaged by vibration. The outer frame 15 is screwed and fixed through the first screw holes 18.

[0015] The adjusting screw 12 is symmetrically equipped with handles 19 at the front and rear. The outer end of the inner plate 11 is equipped with symmetrically opened fixing grooves. A spring rod 21 is arranged in the fixing groove. An outer magnetic plate 22 is installed on the outer end of the spring rod 21. An inner magnetic plate 23 is installed on the outer end of the handle 19. An end cover 24 is screwed onto the outer end of the inner plate 11. The handle 19 is arranged on the inner end of the end cover 24. During operation, the inner magnetic plate 23 and the outer magnetic plate 22 attract and fix each other, thereby preventing the handle 19 from rotating and thus preventing the adjusting screw 12 from rotating accidentally, ensuring the stability of the protective tile 2 installation. The end cover 24 provides sealing protection for the inner magnetic plate 23 and the outer magnetic plate 22, preventing their surfaces from rusting after a long time and making replacement inconvenient.

[0016] The outer frame 15 has symmetrical fixed sliding grooves on its left and right side walls. A first slider 25 is arranged in the fixed sliding groove through a sliding fit. An adjustment frame 26 is installed on the outer end of the first slider 25. A first screw 27 is installed on the bottom of the adjustment frame 26 through a threaded rotation. During operation, rotating the first screw 27 will drive the adjustment frame 26 to move up and down, which facilitates the adjustment of the installation height of the protective tile 2 and further improves the convenience of installing the protective tile 2.

[0017] The bottom of the outer frame 15 has a fixing hole, and a fixing sleeve 28 is rotatably installed in the fixing hole through a bearing. The inner end of the fixing sleeve 28 is fitted with a first screw 27 by a first clip 29. The first slider 25 and the adjusting frame 26 are screwed together by a first bolt 291. During operation, the first clip 29 is used to facilitate the disassembly of the first screw 27, and the first bolt 291 is used to facilitate the disassembly of the adjusting frame 26, so that it can be used flexibly according to the actual installation situation.

[0018] In actual operation, the adjusting screw 12 has symmetrical threads in opposite directions. By rotating the adjusting screw 12, the front and rear positions of the protective tile 2 can be adjusted. The protective tile 2 is equipped with superheater tubes, which makes it easy to adjust the protective tile 2 according to the position of the superheater tubes. This further improves the versatility of the device and enables the protection of multiple superheater tubes.
