A bearing 206 is installed at the bottom of the threaded rod 205, a connecting block 207 is connected to the bottom of the bearing 206, a rubber base 208 is connected to the bottom of the connecting block 207, a limiting groove 214 is provided on the side of the extension block 204, an extension mechanism for improving the anti-falling effect of the smelting furnace is provided on the side of the extension block 204, the connecting seat 201 and the rotating block 202 are rotatably connected, the rotating block 202 and the fixed block 203 are an integrated structure, and a disassembly mechanism for replacing the rubber base 208 is provided at the bottom of the connecting block 207;

[0033] When the protective mechanism of the smelting furnace is in use, pushing the fixed block 203 can drive the rotating block 202 to move. When the rotating block 202 moves, it can rotate through the connecting seat 201. When the fixed block 203 rotates, it can drive the rubber base 208 to rotate through the extension block 204. After the rubber base 208 rotates to the specified position, the threaded rod 205 is rotated. When the threaded rod 205 rotates, it can slide through the extension block 204. When the threaded rod 205 slides, the bearing 206 can be driven to rotate and move. When the bearing 206 rotates, it can drive the threaded rod 205 and the connecting block 207 to rotate. When the bearing 206 moves, it can push the connecting block 207 to move. When the connecting block 207 moves, it can drive the rubber base 208 to move. When the rubber base 208 moves to the ground, it can be squeezed. When the rubber base 208 is squeezed, it can be subjected to the reaction force of the ground. Through the reaction force, the rubber base 208 can support the material box 3 laterally.

[0034] Embodiment 2:

[0035] like Figure 1-Figure 3 The technical solution shown in the figure, the present invention provides the following technical solution: In order to solve the problem that the rubber base 208 of the protection mechanism is easy to wear out after long-term use and is time-consuming to replace, a disassembly and assembly mechanism is disclosed:

When the telescopic block 211 moves, it can slide through the telescopic slot 209 and the clamping slot 213. When the telescopic block 211 slides, it can squeeze the spring 212. When the telescopic block 211 is squeezed out of the clamping slot 213, the rubber base 208 can be separated and disassembled from the connecting block 207. After disassembly, a new rubber base 208 can be replaced, thereby improving the efficiency of replacing the rubber base 208.

[0037] Embodiment three:

[0038] like Figure 1 , Figure 4 Figure 5 , Figure 6 and Figure 7 The technical solution shown in the figure, the present invention provides the following technical solution: In order to solve the problem that the supporting strength of the anti-falling mechanism of the smelting furnace may be insufficient, on the basis of the first embodiment, an extension mechanism is disclosed:

[0039] The extension mechanism includes a limit block 215, and the limit block 215 penetrates and slides inside the limit groove 214, the limit block 215 is fixed inside the fixed block 203, a plurality of first positioning grooves 216 are opened on the top of the extension block 204, a rotating shaft 217 is fixed at the end of the fixed block 203, a rotating rod 218 is rotated inside the rotating shaft 217, a first external block 219 is symmetrically fixed to the end of the fixed block 203 near the rotating shaft 217, a sliding block 220 is slid inside the first external block 219, a second positioning groove 221 is opened at the front of the sliding block 220, a second external block 222 is fixed to the end of the fixed block 203 near the first external block 219, a third positioning groove 223 is opened on the side of the second external block 222, and an extrusion block 224 is fixed inside the rotating rod 218;

[0040] When the protection mechanism increases the protection strength, pushing the rotating rod 218 can drive the extrusion block 224 to move. When the inclined surface of the extrusion block 224 moves to the side of the third positioning groove 223, it can be extruded. When the extrusion block 224 is extruded, the rotating rod 218 can be deformed. When the rotating rod 218 is deformed, the extrusion block 224 can be extruded out of the third positioning groove 223. At this time, the rotating rod 218 can be rotated by the rotating shaft 217. When the rotating rod 218 is rotated, it can be rotated out of the second positioning groove 221. At this time, pulling the extension block 204 can drive the limit groove 214 and the first positioning groove 216 to move. When the limit groove 214 moves, it can slide through the limit block 215. When the first positioning groove 216 moves, the inclined surface of the sliding block 220 can be squeezed. When the sliding block 220 is squeezed, it can slide upward through the first external block 219. When the sliding block 220 slides out of the first positioning groove 216, the extension block 204 can slide inside the fixed block 203. When the extension block 204 slides, the fixed block 203 can be extended. After the extension block 204 extends to a certain position, it can drive the anti-falling mechanism to extend outward. When the anti-falling mechanism is extended, the supporting surface with the ground can be increased. When the supporting surface is increased, the supporting strength of the anti-falling mechanism can be further improved, thereby improving the anti-falling strength of the anti-falling mechanism of the smelting furnace and improving the stability of the smelting furnace.

[0041] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
