Flexible and convenient drop hammer impact testing machine for building material testing

Abstract

The invention discloses a flexible and convenient drop hammer impact testing machine for building material testing, which, in the structure, comprises a limiting top seat, polished rods, a lifter, a drop hammer, a control panel, an impact detection host, base feet and a window, wherein the limiting top seat is fixedly arranged at the upper ends of the polished rods; the polished rods pass throughthe inner part of the lifter; the bottom end of the lifter is provided with the drop hammer; the control panel is embedded on the outer surface of the impact detection host and is electrically connected through a wire; through self impact of the drop hammer, a drop driving mechanism is driven to operate, a first fixing mechanism and a second fixing mechanism tightly fix a detected material, the detected material can be prevented from deviating during the impact detection process, deviation of a detection result is prevented, and after the drop hammer impact, through working of a buffer drop mechanism and a damping base, the self vibration of the drop hammer is reduced, the buffer is reduced, the drop hammer can be prevented from secondary impact, and the secondary impact enables the detected result to be inaccurate.

Description

technical field [0001] The invention relates to the field of flexible and convenient drop weight impact testing machines for building material detection, in particular to a flexible and convenient drop weight impact testing machine for building material detection. Background technique [0002] The drop weight impact testing machine is suitable for impact testing of non-metallic material samples or products such as plastic, glass, ceramics, etc. It is a testing instrument used to evaluate the impact resistance of materials. [0003] However, the current drop weight impact testing machine will have a secondary impact during the impact detection process of building materials, so that the detected results will be biased; The force of the impact is shifted, the part of the impact is shifted, and the detection results will also be biased. Contents of the invention [0004] Aiming at the deficiencies of the prior art, the present invention is realized through the following techn...
