Portable drop hammer deflectometer main body calibration system

Abstract

The invention relates to the technical field of pavement strength detection, in particular to a portable drop hammer deflectometer main body calibration system. The system comprises a deflectometer main body, a chassis is fixed on one side of the deflectometer main body, a connecting mechanism is welded at the top of the chassis, brake wheels are in threaded connection with the bottom of the chassis, so that moving is more convenient, a calibration mechanism is clamped to one end of the connecting mechanism, and the connecting mechanism comprises a storage rod, a first limiting groove, a firstcompression spring, a first limiting block, a sliding block, a telescopic rod, a fixed block, a rotating rod, a connecting clamping block, an adjusting handle, a torsional spring, a fixed rod, a movable clamping block and a connecting base. Through a series of structural designs, the supporting part of the device can be simply and quickly assembled and disassembled, the working efficiency is effectively improved, the device is more portable, the use is more convenient, the calibration efficiency is higher, the risk that easily damaged parts are damaged during transportation is greatly reduced, and the device is more portable.

Description

Technical field [0001] The invention relates to the technical field of road strength detection, in particular to a main body calibration system of a portable drop weight deflection meter. Background technique [0002] The main body of the drop hammer deflection gauge has the advantages of no damage, fast speed measurement, high accuracy, etc., and it simulates the effect of driving load well, and the detection result is the deflection basin data. Therefore, it is increasingly widely used in the world. Its application scope is mainly In terms of road maintenance and management, the detection accuracy of the main body of the falling weight deflection gauge will be affected to a certain extent after a period of use, so it needs to be calibrated to test whether the detection result is accurate to ensure the accuracy of the main body of the deflection gauge However, the supporting part of the main body calibration system of the existing portable drop weight deflection instrument canno...

AI Technical Summary

Problems solved by technology

[0002] The main body of the drop hammer deflection meter has the advantages of no damage, fast measurement speed, high precision, etc., and it simulates the driving load well. The test result is the deflection basin data. Therefore, it is widely used internationally. In terms of road maintenance management, the detection accuracy of the main body of the drop hammer deflection meter will be affected to a certain extent after being used for a period of time, so it needs to be calibrated to test whether the detection results are accurate, so as to ensure the accuracy of the detection of the main body of the deflection meter However, the supporting part of the main body calibration system of the existing portable drop weight deflection meter cannot be retracted and the disassembly is troublesome, often need to screw more screws to complete the installation and disassembly, making its portability poor, and installation and It takes a lot of time to disassemble, and the existing calibration system for the main body of the portable drop weight deflection meter is relatively complicated to use, and it takes more time to test whether the detection results of the main body of the deflection meter are accurate, and the detector, etc. Vulnerable parts often cannot be disassembled from the supporting part and stored separately for transportation, which increases the risk of damage to vulnerable parts during transportation
