一种大型衡器的检定装置

Calibrating device for large-sized weighing apparatus

Abstract

The utility model provides a calibrating device for a large-sized weighing apparatus. The calibrating device comprises calibrating units in the same number as weighing sensors of a detected weighing apparatus and a foundation for supporting each calibrating unit, the foundation is provided with a foundation pit for accommodating the detected weighing apparatus, and a foundation embedded plate is arranged on the foundation on each of two sides of the foundation pit; each calibrating unit comprises a pedestal, a force transducer, a stressing lever, a lever support, a stressing oil cylinder, and a ball head pressure bearing pad centered and placed on the force transducer; and a pressure bearing plate is arranged on a weighing platform of the detected weighing apparatus, one end of the lever support is fixedly connected with the foundation embedded plate, the other end of the lever support is pivoted on the stressing lever, one end of the stressing lever is positioned above the ball head pressure bearing pad and is in contact with the ball head pressure bearing pad, and the other end of the stressing lever is connected with a piston of the stressing oil cylinder through a supporting rod. The verification device has the advantages of greatly improving the working efficiency and the safety of calibration of the large-sized weighing apparatus and saving the cost, and is simple in structure.
本实用新型提供一种大型衡器的检定装置,包括至少与被测衡器的称重传感器数量一致的检定单元和一用于支撑各检定单元的基础,基础上设置一用于容置被测衡器的基坑,且该基坑两侧的基础上分别设置基础预埋板;每检定单元均包含一基座、一力传感器、一加力杠杆、一杠杆支座、一加力油缸、及一对中放置于力传感器上的球头承压垫,承压板置于被测衡器的秤台上,杠杆支座的一端与基础预埋板固定连接,且杠杆支座的另一端枢接于加力杠杆,加力杠杆的一端位于球头承压垫上方且与该球头承压垫接触,加力杠杆的另一端通过一支撑杆与加力油缸的活塞连接。本实用新型的优点在于:不仅可以大大提高检定大型衡器的工作效率和安全性、节约成本,且结构简单。
