基于钢丝绳抗弯刚度的测定原理,研制出一种新型动静态索张力传感器及其张力检测系统.该系统完成了由应变计组成的电桥以及传感器输出信号的调理、预处理和采样,并实时传送至计算机对信号进行存储和处理.能够自动、准确、可靠地测试和分析提升机钢丝绳张力.对易门铜矿矿井提升机钢丝绳进行了现场实测,结果表明:钢丝绳动张力测试最大误差小于1%,静张力最大误差小于0 5%.使用过程证实:该检测仪技术先进、方法正确、测试精度高,符合《矿山安全规程》的规定,适用于现场测试.

According to the principle determining bending stiffness of wirerope,a new type sensor of dynamic and static state tension and testing tension system were developed.The system have many functions such as amplitude modulation and pretreatment and sampling for output singals of electric bridge made up of strain gauge and sensor and can real time send singals to computer memory and manage.It can automatically and accurately and reliably test and analyse hoist wirerope tension.In Yimen copper mine locale,the hoist wirerope tension was tested by the meter.Testing data indicates that maximum error of dynamic tension is less than 1% and maximum error of static tension is less than 0.5%.The application conditions demonstrate that the meter have many advantages such as determining technology in advance and testing method right and testing precision good and testing method of the meter accords also with mine security rules and applies locale measure.
