DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1 , Figure 2 and Figure 4 The utility model provides an embodiment: a new type of permanent layer masonry structure of a steel ladle, including a chassis 1, a fixing mechanism 2 is arranged on the upper side of the chassis 1, a plurality of inner aluminum bricks 2 5 are fixedly connected to the inner side of the top wall of the chassis 1, and the top walls of the plurality of inner aluminum bricks 2 5 are all fitted with inner aluminum bricks 1 3, a plurality of outer aluminum bricks 2 7 are fixedly connected to the outer side of the top wall of the chassis 1, and the top walls of the plurality of outer aluminum bricks 2 7 are all fitted with outer aluminum bricks 1 6, and both sides of the top walls of the plurality of inner aluminum bricks 1 3, the inner aluminum bricks 2 5, the outer aluminum bricks 1 6 and the outer aluminum bricks 2 7 are provided with positioning grooves 1 4, and the plurality of inner aluminum bricks 1 3, the inner aluminum bricks 2 5, the outer aluminum bricks 1 6 and the outer aluminum bricks 2 7 are fixedly connected to the outer side of the top wall of the chassis 1, and the plurality of outer aluminum bricks 2 7 are all fitted with outer aluminum bricks 1 6, and the plurality of inner aluminum bricks 1 3, the inner aluminum bricks 2 5, the outer aluminum bricks 1 6 and the outer aluminum bricks 2 7 are provided with positioning grooves 1 A positioning groove 3 11 is provided in the middle of the bottom wall of the aluminum brick 27, a plurality of outer aluminum bricks 16 and the inner side of the outer aluminum brick 27 are provided with a positioning groove 20, a plurality of inner aluminum bricks 13 and inner aluminum bricks 25 are arranged in a staggered manner, a plurality of outer aluminum bricks 16 and outer aluminum bricks 27 are arranged in a staggered manner, a plurality of inner aluminum bricks 13 and outer aluminum bricks 16 are arranged in a staggered manner, and a plurality of inner aluminum bricks 25 and outer aluminum bricks 27 are arranged in a staggered manner; a positioning block 29 is engaged in the lower positioning groove 14, and the top end of the positioning block 29 is engaged in the upper positioning groove 3 11; a positioning block 8 is fixedly connected to the outer wall of the inner aluminum brick 3, and the outer end of the positioning block 8 is engaged with the positioning groove 2 10;

[0031] Specifically, by providing the masonry between the inner aluminum brick 1 3 and the inner aluminum brick 2 5 and the masonry between the outer aluminum brick 1 6 and the outer aluminum brick 2 7, the aluminum bricks of the upper and lower layers can be staggered, and in the process of masonry of the upper and lower layers of aluminum bricks, the positioning block 2 9 can be inserted into the positioning groove 1 4 of the lower aluminum brick, and then the positioning groove 3 11 of the bottom wall of the upper aluminum brick is inserted into the top of the positioning block 2 9, so that the aluminum bricks on the upper and lower sides can be positioned by the positioning block 2 9 to ensure the accuracy of their installation positions. The masonry between the inner aluminum brick 2 5 and the outer aluminum brick 2 7 can make the aluminum bricks on the inner and outer sides staggered with each other. At the same time, the staff can insert the positioning block 1 8 fixed on the inner aluminum brick into the positioning groove 10 of the outer aluminum brick, so that the inner and outer aluminum bricks can be positioned through the positioning block 1 8 to ensure the relative accuracy of their installation positions. Therefore, by strictly implementing the staggered masonry of two layers of high-aluminum bricks at the production site to form a permanent layer of the ladle, the problem of steel seepage through the air holes of the ladle is solved, and the time for replacing the permanent layer is shortened, ensuring that the ladle can meet production safely and in a timely manner.

[0032] Reference Figure 1 , Figure 2 and Figure 3 The fixing mechanism 2 includes a slide groove 201, and multiple slide grooves 201 are all opened on one side of the inner aluminum brick 1 3 and the inner aluminum brick 2 5. The other side of multiple inner aluminum bricks 1 3 and the inner aluminum brick 2 5 are fixedly connected with a slide bar 203, and multiple slide bars 203 are slidably connected in the slide groove 201. Multiple inner aluminum bricks 1 3 and the inner aluminum brick 2 5 are each provided with a chamber 205, and multiple chambers 205 are slidably connected with a moving block 206, and one side of multiple moving blocks 206 is fixedly connected with a card block 20 4. Multiple blocks 204 are all inserted into the slide groove 201, and the front and rear parts of the other sides of the multiple moving blocks 206 are fixedly connected with one end of the spring 208, and the other ends of the multiple springs 208 are all fixedly connected to the inner wall of the chamber 205; multiple shifting blocks 210 are all slidably connected in the through groove 202; one end of the multiple blocks 204 is provided with an inclined surface; the upper and lower walls of the multiple slide bars 203 are fixedly connected to the limit bars 209, and the multiple limit bars 209 are all slidably connected in the slide groove 201;

[0033] Specifically, when laying the adjacent inner aluminum bricks 1 3 and 2 5, the slide bar 203 can be slid into the slide groove 201 of the adjacent aluminum bricks first, and the two aluminum bricks can be initially limited by the joint action of the limit bar 209. Since the slide bar 203 will contact and squeeze the block 204 when sliding into the slide groove 201, it can push the block 204 to move into the chamber 205 and drive the moving block 206 to move. When the moving block 206 moves, it can compress the spring 208. Therefore, when the slide bar 203 is fully inserted, since the block 204 loses its limit, the spring 208 can push the moving block 206 to reset and drive the block 204 to extend out and be stuck into the slide groove 201 and fit with the front wall of the slide bar 203 for limit, thereby ensuring the stability of the connection between the inner aluminum brick 1 3 or the inner aluminum brick 2 5.

[0034] Reference Figure 1 , Figure 2 and Figure 3 The front and rear parts of the plurality of moving blocks 206 are all penetrated by the limiting rods 207, and both ends of the plurality of limiting rods 207 are fixedly connected to the inner wall of the chamber 205; the inner walls of the plurality of chambers 205 are all provided with through grooves 202, and the inner ends of the plurality of moving blocks 206 are all fixedly connected with the shifting blocks 210.

[0035] Specifically, by setting a limiting rod 207, the moving block 206 can be limited to ensure the stability of the movement of the moving block 206. At the same time, the spring 208 can also be limited to prevent it from bending after being compressed; when it is necessary to disassemble two adjacent aluminum blocks, the staff can drive the moving block 206 to move by turning the shifting block 210, so that the blocking block 204 is pulled out of the slide groove 201, so that the slide bar 203 can be pulled out of the slide groove 201 for disassembly.

[0036] Working principle: In actual use, by setting the masonry between the inner aluminum brick 1 3 and the inner aluminum brick 2 5 and the masonry between the outer aluminum brick 1 6 and the outer aluminum brick 2 7, the aluminum bricks on the upper and lower layers can be staggered. By setting the masonry between the inner aluminum brick 1 3 and the outer aluminum brick 1 6 and the inner aluminum brick 2 5 and the outer aluminum brick 2 7, the aluminum bricks on the inner and outer sides can be staggered. Therefore, by strictly implementing the staggered masonry of two layers of high-aluminum bricks at the production site to form a permanent layer of the ladle, it can not only solve the problem of steel seepage in the ladle's air holes, but also shorten the permanent layer. The replacement time is shortened to ensure that the ladle can meet production safely and in time; in addition, when the adjacent inner aluminum bricks 1 3 and 2 5 are laid, the slide bar 203 can be slid into the slide groove 201 and the block 204 can be squeezed, thereby pushing the block 204 to move into the chamber 205 and compressing the spring 208. When the slide bar 203 is fully inserted, the block 204 can be pushed out and the slide bar 203 can be limited under the action of the spring 208, thereby ensuring the stability of the connection between the inner aluminum bricks 1 3 or the inner aluminum bricks 2 5.
