Description

Technical Field

[0001] The utility model relates to the technical field of hardness detection for refractory brick production, in particular to a hardness detection device for refractory brick production. Background Art

[0002] The primary purpose of hardness testing is to evaluate the mechanical properties and resistance of refractory bricks to external forces, thereby determining whether they meet production and usage requirements. Hardness testing is also a key method of refractory brick quality control. By measuring the hardness of refractory bricks, it can be determined whether they meet predetermined quality standards. Hardness is a key indicator of refractory brick performance, reflecting the brick's mechanical properties such as compressive strength and wear resistance, and directly affecting the brick's service life and stability.

[0003] Existing refractory brick hardness testing typically involves activating a testing device, causing a fixed plate to apply a certain amount of pressure to the refractory brick, and then recording the applied force. The magnitude of this force generally reflects the brick's hardness. However, this force is applied slowly, while under normal use, refractory bricks are typically subjected to rapid impact forces. This results in incomplete hardness testing, necessitating improvements. Utility Model Content

[0026] The detection mechanism 4 includes a sliding rod 42, which is fixedly connected to the top of the fixed seat 3, and the top of the sliding rod 42 is fixedly connected to the support piece 41, and the sliding rod 42 is slidably connected to the sliding seat 43 near the bottom, and the front edge of the sliding seat 43 is fixedly connected to the plug-in rod 44, and the front end of the plug-in rod 44 is plugged with a detection rod 45, and the front end of the detection rod 45 is fixedly connected to a fixed sleeve 46, and a detection spike 48 is plugged into the fixed sleeve 46. Through the detection mechanism 4, the refractory bricks are placed in the first limit block 21 and the second limit block 29. At this time, the sliding rod 42 of the sliding seat 43 is lifted to the top by the upper lifting pin 49. At this time, it is only necessary to loosen the upper lifting pin 49, so that the detection spike 48 can quickly move downward under the action of gravity and pierce the refractory bricks. This can make the refractory bricks receive the effect of force in a fast state, and the hardness state of the refractory bricks can be intuitively judged by the fracture of the refractory bricks after being pierced, which effectively solves the problem that the force is a slow contact force. Under normal use, refractory bricks are generally subjected to a fast impact force, which has the problem of imperfect hardness detection.

[0027] A plug-in slot is provided at the rear end of the detection rod 45, and the plug-in rod 44 is plugged into the plug-in slot of the detection rod 45. A first threaded hole is provided at the connection between the plug-in rod 44 and the detection rod 45, and a first limit screw 451 is threadedly connected in the threaded holes of the plug-in rod 44 and the detection rod 45.

Through the setting of the limiting mechanism 2, the refractory brick is placed in the first limiting block 21 and the second limiting block 29. At this time, the limiting rod 23 is pulled toward the outside of the second limiting block 29 by the toggle ring. When the refractory brick is placed in the block, the toggle ring is released. Under the action of the spring 25, the limiting piece 22 and the refractory brick can be tightly fitted, which can ensure that during the refractory brick detection process, no accident will occur when the detection spike 48 pierces the refractory brick, thereby further ensuring the accuracy of the detection.

[0033] During actual operation, when this device is used, the refractory bricks are placed in the first limit block 21 and the second limit block 29. At this time, the sliding rod 42 of the sliding seat 43 is lifted to the top by the upper lifting pin 49. At this time, it is only necessary to loosen the upper lifting pin 49, so that the detection spike 48 can quickly move downward under the action of gravity and pierce the refractory bricks. This can allow the refractory bricks to receive the force in a fast state, and the hardness state of the refractory bricks can be intuitively judged by the fracture of the refractory bricks after being pierced, which effectively solves the problem that the force is a slow contact force. Under normal use, refractory bricks are generally subjected to a fast impact force, which has the problem of imperfect hardness detection.

[0034] Place the refractory brick in the first limit block 21 and the second limit block 29, and pull the limit rod 23 out of the second limit block 29 through the toggle ring. When the refractory brick is placed in the block, release the toggle ring. Under the action of the spring 25, the limit plate 22 and the refractory brick can be tightly fitted, which can ensure that during the refractory brick inspection process, no accident will occur when the inspection spike 48 pierces the refractory brick, further ensuring the accuracy of the inspection.
