摘要:
This invention is intended to use for diagnostics of various ropes in lifting equipment. Aim of invention - to create new and quite simple non-destructive method for rope quality diagnostics and estimate special equipment for realization of such method. Proposed method is based on obtaining fact of broken rope wires on rope surface. To achieve this rope is tensed by permanent axial load, rope is excited by transverse vibrations using vibrator, which are inducing transverse rotational vibrations. Oscillations of free ends of broken wires are measured by set of sensors and after signals are processed, presence and positions of broken wires are detected. Vibrator for rope excitation and set of sensors are mounted on special frame, which is tightly clamped on rope and separated fragment of rope, where vibrations are excited, set of sensors are moved along tested rope fragment. Procedure is repeated in next fragment of rope until all length of rope is tested.
摘要(中):
本发明旨在用于起重设备中各种绳索的诊断。 发明目标 - 为绳子质量诊断创造新的非常简单的非破坏性方法,并估计用于实现这种方法的特殊设备。 提出的方法是基于获得绳索表面上断绳索的事实。 为了实现这种绳索由永久轴向载荷拉紧,使用振动器的横向振动激励绳索,这引起横向旋转振动。 断线自由端的振荡由一组传感器测量,并且在信号被处理之后,检测到断线的存在和位置。 用于绳索激励的振动器和传感器组安装在专门的框架上,紧紧地夹在绳索上并分离出绳索的碎片,激励振动,传感器组沿测试的绳索片段移动。 在绳索的下一个片段中重复步骤,直到测试所有长度的绳索。
