[0031] Embodiment 1:

[0032] An impact-resistant wear-resistant hanging brick for a kiln tail smoke chamber, such as Figure 1As shown, it includes a type I wear-resistant hanging brick 10 and a type II wear-resistant hanging brick 20 which are closely laid and fixedly connected to the top of the kiln tail smoke chamber;

[0033] The first type wear-resistant hanging brick 10 is a hexagonal prism structure, and has a disassembly and assembly through hole 101 passing through its axis. The top of the first type wear-resistant hanging brick 10 has a connecting and matching hexagonal hole 11 connected to the disassembly and assembly through hole 101;

[0034] The type II wear-resistant hanging brick 20 is a hexagonal column structure, and is provided with a disassembly and assembly connection through hole 201 that passes through its axis.

[0035] like Figure 1 As shown, the type I wear-resistant hanging brick 10 is fixedly connected to the top of the kiln tail smoke chamber through a quick disassembly structure 31, and the quick disassembly structure 31 includes a plurality of quick disassembly fixing columns 311 fixed to the top of the kiln tail smoke chamber, and a plurality of elastic connecting rods 312 are fixed to the lower end of the quick disassembly fixing column 311, and a quick disassembly connecting ball 313 is fixed to the lower end of the elastic connecting rod 312;

[0036] The multiple elastic connecting rods 312 are arranged gradually from top to bottom;

[0037] Each inner side wall of the connecting and fitting hexagonal hole 11 is provided with a quick disassembly and assembly fitting hole 310, and a quick disassembly and assembly connecting ball 313 is clamped and constrained in the quick disassembly and assembly fitting hole 310;

[0038] An elastic rod restraint ring 314 is commonly sleeved around the outer periphery of the plurality of elastic connecting rods 312, and a restraint pull rod 315 is fixedly connected to the inner side of the elastic rod restraint ring 314. The restraint pull rod 315 passes through the disassembly and assembly matching through hole 101 and extends to the lower side of the type I wear-resistant hanging brick 10.

[0039] like Figure 1 As shown, the type II wear-resistant hanging brick 20 is fixedly connected to the top of the kiln tail smoke chamber through a flexible connection structure 32. The flexible connection structure 32 includes a plurality of flexible connection fixing plates 321 fixed to the top of the kiln tail smoke chamber. A vertically extending flexible connection fixing rod 322 is fixed to the lower end of the flexible connection fixing plate 321. A flexible connection top pressure ring 323 is slidably connected to the flexible connection fixing rod 322. A plurality of elastic plates 324 are fixed between the lower side of the flexible connection fixing plate 321 and the top of the flexible connection top pressure ring 323.

[0040] The type II wear-resistant hanging brick 20 is passed through the disassembly connection through hole 201 and is arranged at the lower end of the flexible connection fixing rod 322, and the flexible connection top pressure ring 323 is supported by top pressure on the top of the type II wear-resistant hanging brick 20;

[0041] like Figure 3As shown, the lower end of the type II wear-resistant hanging brick 20 has a tapered hole 202 with an opening facing downward and connected to the disassembly connection through hole 201, a fixed cone 325 is connected in the tapered hole 202, and the fixed cone 325 has a tapered through hole 326 passing through along its axis, and the fixed cone 325 is penetrated through the tapered through hole 326 and is arranged at the lower end of the flexible connection fixing rod 322, and the inner side wall of the tapered through hole 326 has a fixed constraint annular groove 327, and the outer side wall of the lower end of the flexible connection fixing rod 322 has a matching constraint annular groove 328, and two fixed constraint semi-rings 329 are arranged between the fixed constraint annular groove 327 and the matching constraint annular groove 328;

[0042] The fixed cone 325 is composed of two “half cones” cut along its radial plane, and the fixed cone 325 is made of the same material as the second type wear-resistant hanging brick 20.

[0043] like Figure 1 As shown, the side of the type-1 wear-resistant hanging brick 10 has a slope that is wider at the bottom and narrower at the top, and the side of the type-2 wear-resistant hanging brick 20 has a slope that is narrower at the bottom and wider at the top. The slope of the side of the type-1 wear-resistant hanging brick 10 is consistent with the slope of the side of the type-2 wear-resistant hanging brick 20, and the slope size is 1:15. Every six of the type-1 wear-resistant hanging bricks 10 form a circle to surround a type-2 wear-resistant hanging brick 20.

[0044] The elastic connecting rod 312 and the elastic plate 324 are made of a material code-named GH4169.

[0045] Embodiment 2:

[0046] The difference from Example 1 is that the slope of the side of the type I wear-resistant hanging brick 10 and the slope of the side of the type II wear-resistant hanging brick 20 are 1:8;

[0047] The elastic connecting rod 312 and the elastic plate 324 are made of a material code-named GH4145.

[0048] In the actual application process of the utility model, the second type of wear-resistant hanging brick 20 is installed first and then the first type of wear-resistant hanging brick 10 adjacent thereto is installed;

[0049] The second wear-resistant hanging brick 20 is passed through the disassembly and assembly connection through hole 201 on the flexible connection fixing rod 322, and the matching constraint ring groove 328 is leaked from the lower end of the second wear-resistant hanging brick 20, and the two fixed constraint semi-rings 329 are clamped in the matching constraint ring groove 328, and then the fixed cone 325 of the two half structures is surrounded on the outer side of the lower end of the flexible connection fixing rod 322. At this time, the two fixed constraint semi-rings 329 are also clamped in the fixed constraint ring groove 327, and the second wear-resistant hanging brick 20 is released to make the second wear-resistant hanging brick 20 move down along the flexible connection fixing rod 322, so that the entire fixed cone 325 is clamped in the conical hole 202, and the flexible connection top pressure ring 323 is pressed and contacted on the top of the second wear-resistant hanging brick 20, and under the elastic force of the elastic plate 324, the flexible connection top pressure ring 323 applies a downward prestress to the second wear-resistant hanging brick 20;

[0050] The first type wear-resistant hanging brick 10 is passed through the disassembly and assembly through hole 101 on the constraint rod 315. When the constraint rod 315 leaks out from the lower side of the first type wear-resistant hanging brick 10, the constraint rod 315 is pulled downward, and the constraint rod 315 drives the elastic rod constraint ring 314 to move downward. Under the constraint of the elastic rod constraint ring 314, the lower ends of the multiple elastic connecting rods 312 are close to each other, so that the multiple quick-disassembly and assembly connecting balls 313 are also close to each other, and then the multiple quick-disassembly and assembly connecting balls 313 are extended into the connecting and fitting hexagonal holes 11;

[0051] Then, the restraining rod 315 is pushed upward, and the restraining rod 315 drives the elastic rod restraining ring 314 to move upward. Under the recovery of the elastic force of the multiple elastic connecting rods 312, the lower ends of the multiple elastic connecting rods 312 move away from each other, so that the multiple quick-disassembly connecting balls 313 also move away from each other. At this time, the multiple quick-disassembly connecting balls 313 are correspondingly inserted into the quick-disassembly matching holes 310 one by one, and the installation of the type I wear-resistant hanging brick 10 is completed;

[0052] By performing the above steps in reverse order, the type I wear-resistant hanging brick 10 and the type II wear-resistant hanging brick 20 can be quickly disassembled and replaced.
