Horizontal inductive tension detecting device for steel wire rope and horizontal inductive tension detecting method for same

Abstract

Disclosed are a horizontal inductive tension detecting device for a steel wire rope and a horizontal inductive tension detecting method for the same. The horizontal inductive tension detecting device comprises a shell symmetrically and fixedly fastened on the steel wire rope, two bases are symmetrically arranged in the shell, sliding rods extending out of the corresponding bases are arranged in the two bases respectively, a roller abutted to the steel wire rope is arranged at the top of each sliding rod, a base plate fixed onto the corresponding base is sleeved at the tail of each sliding rod, insulating sleeves are symmetrically arranged on the upper portion and the lower portion of the right end face of each base plate, a sliding plate is arranged in the middle of each sliding rod, a spring sleeved on the corresponding sliding rod is arranged between each sliding plate and the corresponding base plate, cylindrical magnetic conducting iron cores in clearance fit with the insulating sleeves are symmetrically arranged on the upper portion and the lower portion of the left end face of each sliding plate, and a signal processing unit connected with a connecting terminal is arranged on the left end face of each base plate. Coil inductance changes along with the diameter of the steel wire rope and is converted into voltage signals through a bridge circuit, and finally the voltage signals are converted into the tension of the steel wire rope. The horizontal inductive tension detecting device is simple in structure, convenient in installation, high in measuring precision and capable of accurately measuring the tension of the steel wire rope in real time.

Description

technical field [0001] The invention relates to a transverse inductive steel wire rope tension detection device and method, which is especially suitable for detecting the real-time tension of steel wire ropes when equipment such as hoists, elevators, and winches are hoisted or pulled, and belongs to the technical field of equipment detection and safety. Background technique [0002] As a key component of traction and load-bearing, steel wire rope is widely used in various fields of national economic construction such as coal mines, metallurgy, high-rise building lifting, transportation, etc. The change of its tension reflects the important operating status information of steel wire ropes and related equipment. At present, the main methods of wire rope tension detection are divided into three categories: one is the percussion vibration wave method, which mainly uses the relationship between the tension and the vibration frequency of the wire rope or the propagation speed of th...
