[0027] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without violating the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Refer to the attached Figure 1 and attached Figure 2 The present embodiment provides a clamp for curing the anti-corrosion layer of the lining sleeve, including a first hoop frame 1 and a second hoop frame 2. The top plate 11 of the first hoop frame 1 and the top plate 11 of the second hoop frame 2 are hinged, and the bottom plate 12 of the first hoop frame 1 and the bottom plate 12 of the second hoop frame 2 are detachably connected. A splint 13 is provided between the bottom plate 12 and the top plate 11. The splint 13 is provided with a clamping groove 131 adapted to the lining sleeve 3. When the two splints 13 clamp the lining sleeve 3, gaps are left between the top plate 11 and the bottom plate 12 and the two ends of the lining sleeve 3 respectively. The width of the splint 13 is smaller than the width of the top plate 11 and the bottom plate 12 respectively. The structure of the first hoop frame 1 is the same as that of the second hoop frame 2. In the present invention, the first hoop frame 1 and the second hoop frame 2 are opened, the lining sleeve 3 is placed between the two clamping plates 13, and then the clamping groove 131 is clamped in the groove of the lining sleeve 3, and the two bottom plates 12 are connected so that the clamping plates 13 clamp the lining sleeve 3. At this time, the two ends of the lining sleeve 3 do not contact the bottom plate 12 and the top plate 11, and the first hoop frame 1 and the second hoop frame 2 do not contact the inside of the lining sleeve 3. When the lining sleeve 3 is placed in the furnace for curing by the clamp, the internal anti-corrosion layer of the lining sleeve 3 will not be damaged, which is conducive to improving the service life of the lining sleeve 3. Secondly, the structure of the clamp is simple, easy to make, and there are fewer steps for fixing the lining sleeve 3, which is conducive to improving the curing efficiency of the lining sleeve 3.

[0029] As another embodiment of the present invention: Figure 3 The width of the bottom plate 12 is smaller than that of the top plate 11, and a fixing rod 14 is provided on both sides of the bottom plate 12. The fixing rod 14 facilitates the opening and closing of the two splints 13. When the splints 13 clamp the lining sleeve 3, the fixing rods 14 on the same side of the two splints 13 can be tied tightly with wire. Of course, a pull rod can be hinged on one fixing rod 14, and a locking nut is threaded on the pull rod. The other fixing rod 14 is provided with a U-shaped groove that matches the pull rod. After the pull rod is inserted into the U-shaped groove, the locking nut is tightened to fix the fixing rods 14 on the same side of the two splints 13. If the lining sleeve 3 needs to be cured vertically, when the two splints 13 are clamped in the groove of the lining sleeve 3, the weight of the lining sleeve 3 itself can be used to naturally tighten the clamp, and damage-free clamping can be achieved during the curing process. At the same time, the simple clamping process is also conducive to improving the curing efficiency of the lining sleeve 3.

[0030] As another embodiment of the present invention: a first weight-reducing hole 121 is provided on the bottom plate 12 to reduce the weight of the clamp and lower the manufacturing cost of the clamp.

[0031] An embodiment of hinged connection of two top plates 11: Figure 4 A hinge 4 is provided between the two top plates 11. This structural design reduces the difficulty of manufacturing by using existing parts.

[0032] As another embodiment of the present invention: both sides of the hinge 4 are respectively welded and fixed to the two top plates 11 .

[0033] As another embodiment of the present invention, a gap is provided between the two top plates 11 .

[0034] As another embodiment of the present invention: a second weight-reducing hole 111 is provided on the top plate 11 to reduce the weight of the clamp and lower the manufacturing cost of the clamp.

[0035] As another embodiment of the present invention: Figure 5 A third lightening hole 132 is provided on the clamping plate 13 to reduce the weight of the clamp and lower the manufacturing cost of the clamp. A reinforcing plate 15 is fixed in the third lightening hole 132. The reinforcing plate 15 is connected to the side opposite the bottom of the clamping groove 131. The provision of the reinforcing plate 15 improves the structural strength of the clamping groove 131 on the clamping plate 13.

[0036] As another embodiment of the present invention: the first hoop frame 1 and the second hoop frame 2 are both provided with a vertical rod 16, and the top plate 11, the clamping plate 13 and the bottom plate 12 are all fixed on the vertical rod 16. Through this structural design, it is beneficial to make the structure of the clamp simple.

[0037] As another embodiment of the present invention, two vertical rods 16 are respectively provided on both sides of the clamping plate 13 , and the top plate 11 and the bottom plate 12 are both fixed by the two vertical rods 16 .

[0038] Specifically, the top plate 11 , the clamping plate 13 and the bottom plate 12 have the same length.

[0039] In the present invention, the first hoop frame 1 and the second hoop frame 2 are opened, the lining sleeve 3 is placed between the two clamps 13, and then the clamps 13 are closed to clamp the lining sleeve 3, and the two bottom plates 12 are connected so that the lining is fixed on the fixture. At this time, the two ends of the lining sleeve 3 do not contact the bottom plate 12 and the top plate 11, and the first hoop frame 1 and the second hoop frame 2 do not contact the inside of the lining sleeve 3. When the lining sleeve 3 is placed in the furnace for curing through the fixture, the internal anti-corrosion layer of the lining sleeve 3 will not be damaged, which is conducive to improving the service life of the lining sleeve 3. Secondly, the fixture has a simple structure and is easy to make. The process of fixing the lining sleeve 3 is small, which is conducive to improving the curing efficiency of the lining sleeve 3.

[0040] Finally, the method of the present invention is only a preferred embodiment and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.

[0041] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations shall fall within the scope defined by the appended claims.
