摘要
目前,起重机械轮压值主要来自理论计算或测量轨道的应变,其结果并不十分准确。直接将设备安装于码头或厂房结构会导致一定的安全隐患,给特种设备检验带来困难。文中研究测量大型起重机械设备轮压的传感技术,通过利用微应变传感器的方法将常规设备无法测量的大型起重机械轮压转化为可测量的物理量,实现轮压测量。轮压测量可应用于设备的验收、型式试验、监督检验和安全性评估工作,同时可应用于厂房、码头和货场等建筑结构的承载能力安全评估工作。
Currently,the wheel pressure values of hoisting machinery are primarily obtained through theoretical calculations or measurements of track strain,which often yield results with limited accuracy.When such equipment is directly installed in docks or factory buildings,these inaccuracies can pose potential safety hazards and complicate the inspection of special equipment.The sensing technology for measuring the wheel pressure of large cranes was studied.By employing micro-strain sensors,the wheel pressure of large cranes,which cannot be measured using conventional equipment,was transformed into a measurable physical values,thereby enabling accurate wheel pressure measurement.This technology can be applied to various stages of equipment management,including acceptance testing,type testing,supervision and inspection,and safety evaluation.Additionally,it can be used for the safety assessment of the load-bearing capacity of structures such as factories,docks,and freight yards.
