Description

Multi-rope hoisting steel wire rope tension sensor

Technical Field

The utility model relates to a many ropes tension sensor technical field specifically is many ropes hoisting wire rope tension sensor.

Background

The tension sensor is also called a tension detector, and is an instrument for measuring the tension value of the coiled material in the tension control process. According to its working principle, it can be divided into strain gauge type and micro-displacement type. The strain gauge type is that a tension strain gauge and a compression strain gauge are connected together in a bridge mode, the resistance value of the strain gauge is changed when external pressure is applied, and the change value is in direct proportion to the magnitude of the applied tension; the micro-displacement type is a type in which a load is applied by an external force to displace a plate spring, and then a tension is detected by a differential transformer, and is called a micro-displacement type tension detector because the displacement amount of the plate spring is extremely small, about ± 200 μm. In addition, the external structure is divided into: pivot type, through-pivot type, cantilevered type, etc.

The existing multi-rope tension sensor is not small and exquisite enough, and is not simple and convenient enough when measuring the tension of a steel wire rope.
