Description

Calibration metering equipment for experimental impact device Technical Field The utility model relates to the field of experimental equipment metering, in particular to a calibration metering device for an experimental impact device. Background In the development of the modern industry, calibrated metering devices are widely used in scientific research and laboratories. Because scientific experiments require accurate measurements to prove the correctness of a certain observation or theory, and to perform corresponding analyses and statistics, the precision and accuracy of the associated calibrated metrology device is critical. Calibration metrology devices are of many different kinds, and the accuracy class of the calibration metrology device is also of a high-low class, depending on the application and accuracy requirements. In particular, for both electrical and non-electrical explosion-proof equipment, it is necessary to verify the strength of its metallic or non-metallic housing during the pattern test and to investigate the impact test results on the subsequent temperature rise test, IP grade test or non-booster test. However, as the explosion-proof industry advances, particularly the demand for explosion-proof outlets of non-electrical plants increases, the number of related explosion-proof certification projects increases year by year, and the limitations of the conventional test impact devices are gradually revealed. Because the traditional impact device impacts the upper surface of the equipment by means of gravity, any surface of the handheld equipment or the small equipment can be conveniently adjusted to the horizontal surface for impact, but for the large equipment or the complete equipment, the expected impact surface of the large equipment or the complete equipment is difficult to adjust to the horizontal for receiving the vertical impact test, or the single placement direction can be maintained due to the function requirement. Because large equipment or plants may actually be impacted in a lateral or horizontal direction during the application process, which in turn affects the explosion protection safety, the impact test requirements in the lateral (e.g., vertical) horizontal direction still remain. Although the vertical impact test performed by the impact device on the market is wider, the impact energy of the impact device also lacks the reliability and stability of calibrating or metering the impact device by corresponding calibration metering equipment, so the metering problem calibration work of the impact device is usually evaluated by a theoretical calculation mode, and lacks reliable data support, thus easily making people doubt the accuracy degree of the impact device and the authority of laboratory setting. There is no good solution to the above problems in the market.

In practice, the standard height gear tool serves as a standard position caliper structure corresponding to the metering drop hammer. The bottom of the measuring drop hammer is leveled with a certain line position on the standard height gear tool, the measuring drop hammer and the standard height gear tool can be connected through a horizontal line or a horizontal rod, and the current standard height of the measuring drop hammer can be recorded through the observation of the corresponding line position. The standard height gear tool can be used for metering and adjusting according to different metering requirements, and the metering drop hammer is assisted to be adjusted to the standard height required by metering. The drop hammer retraction tool, the suspension wire guiding tool and the standard height gear tool can be realized by adopting the prior art.
