The invention relates to the technical field of safety detection of hoisting equipment, in particular to a rigging looseness prevention and rope breakage detection mechanism which comprises a base, a spring assembly, a sensor module and a control unit, the spring assembly comprises a spring seat, a mandrel and a pre-pressing spring, the spring seat is in sliding connection with the base through the mandrel, and the mandrel is sleeved with the pre-pressing spring; the spring seat is fixedly connected with one end of the rigging, and the pre-pressing spring deforms along with the change of the tensioning force of the rigging; the sensor module comprises a first sensor and a second sensor, and the first sensor is used for detecting a loosening threshold deformation signal of the pre-pressing spring when the rigging is in a pre-tightening state; the second sensor is used for detecting a rope breaking threshold deformation signal of the pre-pressing spring when the rigging is in a rope breaking failure state; when the control unit receives a signal of the first sensor, the control unit controls the rigging to stop lowering; and when the signal of the second sensor is received, the second sensor controls the hoisting equipment to stop and starts the mechanical braking device. The device is simple in structure, low in cost and easy to install and maintain.
本发明涉及起重设备安全检测技术领域,具体涉及一种索具防松及断绳检测机构,包括基座、弹簧组件、传感器模块和控制单元,弹簧组件包括弹簧座、芯轴及预压弹簧,弹簧座通过芯轴与基座滑动连接,预压弹簧套设在芯轴上;弹簧座与索具一端固定连接,预压弹簧随索具张紧力变化产生形变;传感器模块包括第一传感器和第二传感器,第一传感器用于检测索具处于预紧状态时预压弹簧的松脱阈值形变信号;第二传感器用于检测索具处于断绳失效状态时预压弹簧的断绳阈值形变信号;当控制单元接收到第一传感器的信号时,其控制索具停止下放动作;当接收到第二传感器的信号时,其控制起重设备停机并启动机械制动装置。本发明结构简单、成本低、易于安装和维护。
