Background

The compaction apparatus can be divided into a soil compaction apparatus and a Marshall compaction apparatus according to the application. The geotechnical compaction instrument is a geotechnical test instrument which utilizes a standard compaction method to measure the maximum dry density and the optimal water content of cohesive soil under the given compaction function. The Marshall compaction tester is basic equipment for indoor asphalt mixture test piece manufacturing, and is suitable for molding cylindrical test pieces of asphalt mixture Marshall tests, indirect tensile tests and the like. The compaction instrument is one of the most commonly used devices of test detection units such as highway engineering test detection mechanisms, construction site laboratories and the like, is widely used due to the characteristics of simple structure, stability, reliability, strong applicability and the like, and is also a necessary tool.

As specified by relevant industry management practices, the compaction apparatus needs to be calibrated regularly, and the most important calibration/calibration item is the drop distance (to ensure that compaction work meets the requirements). The existing drop distance calibration method is to use a steel ruler as a measuring tool for estimation and reading after the human eye vision positioning, and has the following defects: the steel ruler is manually fixed in a close distance, so that potential safety hazards exist; the highest lifting height of the compaction instrument needs to be positioned by manual vision, and then a measurement result is estimated and read by using a straight steel ruler, so that a larger measurement error exists; because of relying on the artificial vision to fix a position the highest lifting height of the compaction instrument, in order to reduce the measurement error as far as possible, generally all need repeated positioning many times, have the problem that work efficiency is low.

In order to break through key technology research, on the basis of not reducing the measurement accuracy of the existing technical standard, the existing calibration method is improved, a compaction instrument drop distance calibration device integrating the functions of safe control, accurate measurement, quick positioning and the like is developed, and the device has important significance for improving the working efficiency, data accuracy, economy and safety of daily metrological verification/calibration.
