Description
Technical Field
[0001] The utility model belongs to the technical field of protective devices, and in particular relates to a protective device for strength detection of corundum bricks. Background Art
[0002] Corundum brick refers to a refractory brick made of corundum. It is a solid solution synthesized by high-temperature melting of alumina and chromium oxide in a certain proportion. Corundum brick has good high-temperature stability, wear resistance, corrosion resistance and thermal shock resistance. It is widely used in high-temperature kilns in metallurgy, glass, cement, ceramics, electric power and other industries. The strength test of corundum brick is an important means to ensure its quality and safety, and it is also an indispensable link in industrial production. At present, the strength test of corundum brick generally uses flexural testing equipment to conduct a fracture test on the corundum brick sample. The flexural strength of the corundum brick sample is detected by applying external force to the sample until it breaks. However, during the test, when the brick body suddenly breaks, it will generate a large elastic force, which may easily cause part of the brick body or debris to fly and cause harm to the operator, thus posing a safety hazard. Summary of the invention
[0003] The utility model provides a protective device for corundum brick strength detection, which has the characteristics of being able to prevent part of a larger brick body or debris from flying outwards due to the elastic force generated when the brick is broken, thereby causing damage to the detection device or the operator.

At this time, the staff will control the two protective plates 21 to rotate upward in turn. During the upward rotation process, the protective plates 21 can drive the sleeve 22, the extrusion rod 23 and the mounting plate 3 to move synchronously. The extrusion part 31 will gradually move to contact with the top of the corundum brick, and will be squeezed by the top of the corundum brick to gradually drive the extrusion rod 23 to slide toward the inside of the sleeve 22. Wait until the two protective plates 21 are rotated upward to a vertical state and When one side of the mounting frame 11 is fitted, the sleeve 22 and the extrusion rod 23 will also move synchronously to a vertical state.
