Description

[0002] The refractory material impact resistance test device is a device specially used to test the performance of refractory materials when subjected to impact loads. This device can simulate the impact conditions that may be encountered in actual use, so as to evaluate the safety of refractory materials when subjected to impact. When conducting an impact resistance test, first place the refractory sample on the sample holder, and then start the impact tester to apply a predetermined impact load. During the impact process, the data acquisition system will record the deformation, rupture, etc. of the sample in real time, as well as parameters such as force and speed during the impact process.

[0003] After searching, the utility model patent with Chinese patent publication number CN216484425U discloses a device for testing the impact resistance of reflective film, which belongs to the field of reflective film inspection devices. The device comprises a platform, four symmetrically arranged threaded columns are fixedly installed on the upper end of the platform, and the four threaded columns are all threadedly connected with threaded rods, a connecting disc is fixedly installed on the side wall of the threaded rod, a sliding block is rotatably connected to the connecting disc, an extrusion block is fixedly installed on the lower end of the sliding block, a supporting frame is fixedly installed on the upper end of the platform, an electric push rod is fixedly installed on the side wall of the supporting frame, an impact plate is fixedly installed on the lower end of the electric push rod, and a pressure sensor is fixedly installed on the lower end of the impact plate through a clamping block, which facilitates the stable fixing of the reflective film, thereby facilitating the impact test of the reflective film by the impact plate, and at the same time, the buffer block facilitates the buffering of the impact plate to prevent damage to the impact plate and the pressure sensor, and the device has a simple structure and is easy to use.

[0004] Upon searching the above patent, it was found that the device has dealt with the stable fixation of the object, but the device has failed to deal with the splashing waste generated by the object during the impact test. When the object cannot withstand the impact of the impact test, the object will break into pieces and produce a large amount of waste. At the same time, a large amount of waste will splash everywhere, which may easily cause harm to the operators around the device. Utility Model Content
