[0022] In this embodiment, when installing the protective wear-resistant tile body 1 and the retaining ring 2, the inner walls of the protective wear-resistant tile body 1 and the retaining ring 2 can be fitted to the outer wall of the tube body 3, and the limit block 4 can be inserted into the inside of the limit opening 5, and the limit pin 7 can be inserted into the inside of the second positioning block 8, so as to facilitate the limiting of the protective wear-resistant tile body 1 and the retaining ring 2. At this time, the nut 9 is screwed to one end of the limit pin 7, and the protective wear-resistant tile body 1 and the retaining ring 2 can be assembled together and initially installed on the outer wall of the tube body 3.

[0023] Embodiment 2:

[0024] like Figure 1-4 As shown, a protective groove 17 is provided in the middle of the inner wall of the snap ring 2, and an arc-shaped clamping plate 16 is movably sleeved inside the protective groove 17. The inner wall of the arc-shaped clamping plate 16 is provided with anti-slip grooves. A protective cover 10 is fixedly connected to the middle of the outer wall of the snap ring 2, and a push plate 13 is provided inside the protective cover 10. Two push rods 15 are symmetrically fixedly connected to the right side of the push plate 13. One end of the push rod 15 extends to the inside of the protective groove 17 and is fixedly connected to the outer wall of the arc-shaped clamping plate 16. A screw rod 12 is provided inside the protective cover 10, and the right end of the screw rod 12 is rotatably connected to the middle of the outer wall of the snap ring 2. The left end of the protective cover 10 extends to the left side of the protective cover 10 and is fixedly connected with a knob 11. The middle part of the push plate 13 is threadedly sleeved on the outer wall of the screw rod 12. Two guide rods 14 are slidably sleeved inside the push plate 13. The right end of the guide rod 14 is fixedly connected to the outer wall of the clamping ring 2. The left end of the guide rod 14 is fixedly connected to the left side of the inside of the protective cover 10. A protective cap 18 is provided on the left side of the protective cover 10. The knob 11 is located inside the protective cap 18. An annular connecting port 19 is opened on the left side of the protective cover 10. The right side of the protective cap 18 is threadedly sleeved inside the annular connecting port 19.

[0025] In this embodiment, the provision of the protective cap 18 facilitates the protection of the knob 11. When the protective wear-resistant shoe body 1 and the retaining ring 2 are assembled on the outer wall of the tube body 3, the protective cap 18 is removed by screwing, and the knob 11 and the screw 12 are rotated. The screw 12 can drive the push plate 13 to move horizontally on the outer wall of the guide rod 14. The provision of the guide rod 14 facilitates the horizontal guidance of the push plate 13.

[0026] In summary, if Figure 1-4As shown, when using the protective wear-resistant tile, the inner wall of the protective wear-resistant tile body 1 is moved to the outer wall of the tube body 3 of the boiler heating surface, and then the clamping ring 2 is moved to the other side of the outer wall of the tube body 3, and the clamping ring 2 drives the limit block 4 to be inserted into the limit opening 5 at both ends of the protective wear-resistant tile body 1. At the same time, the clamping ring 2 drives the limit pin 7 to be inserted into the second positioning block 8 through the first positioning block 6. At this time, the nut 9 is spirally connected to one end of the limit pin 7, and one side of the nut 9 is pressed tightly against one side of the second positioning block 8, so that the protective wear-resistant tile body 1 and the clamping ring 2 are limited, and the protective wear-resistant tile body 1 and the clamping ring 2 are initially installed on the outer wall of the tube body 3. , then spirally remove the protective cap 18, and rotate the knob 11. The knob 11 drives the screw rod 12 to rotate, and the screw rod 12 simultaneously drives the push plate 13 to move horizontally on the outer wall of the guide rod 14, and makes the push plate 13 drive the arc clamping plate 16 to move through the push rod 15, so that the arc clamping plate 16 applies a resisting pressure to the left side of the outer wall of the tube body 3, and at the same time makes the inner wall of the protective wear-resistant tile body 1 tightly fit against the outer wall of the tube body 3 to protect the tube body 3, and then spirally install one end of the protective cap 18 inside the annular connecting port 19 to facilitate the protection of the knob 11. In this way, the inner wall of the protective wear-resistant tile body 1 can be tightly installed on the tube body 3.
