Description
Technical field
The utility model is related to cable force measurement and its structural safety monitoring field, and more particularly to a kind of intelligent cable is fixed
Nut.
Background technology
Suo Li change is to weigh the important symbol whether wire rope assemblies is in normal operating condition.Cable is a kind of
Internal high order redundant structure, can make the linear and internal stress of cable reach perfect condition by adjusting the Suo Li of drag-line.
But, if Suo Li, which deviate from it, designs Suo Li, this deviation can not only make to produce unbalance loading between cable, can also make Sarasota and
Girder produces moment of flexure.By the on-line monitoring to wirerope cable force, the dynamic change trend of wirerope cable force can be not only obtained,
Foundation can also be provided for the technology status overall assessment of cable；In addition, to a certain extent may be used by the monitoring to Suo Li
It is the timely and effective dimension of cable to find whether anchor system, the guard system of drag-line are intact, and whether cable wire occurs corrosion etc.
Shield provides data supporting.
The method of traditional cable force measurement mainly has pressure-bearing type pressure sensor, i.e. rope meter, pressure rings class sensor.But
It is, because using the measurement of direct pressure-bearing type, the volume that there is sensor is larger, the problems such as installation difficulty is larger；Simultaneously as this
Class sensor belongs to two kinds of structures with cable body, and the compatibility issue of installation dimension is often resulted in when actual design is applied, is existed
Certain deficiency.
In recent years, the unit such as each research institutions have devised a kind of built-in optical fiber grating sensor, i.e., by fiber grating
Sensor is fused to inside cable body, when Dang Suoli changes, and fiber grating internal stress changes, to the light wave reflected
Length generates phase shift, and the change for measuring launch wavelength by harvester obtains its rope force value.But because cable is in production, fortune
The damage of fiber-optic grating sensor is easily caused in the links such as defeated, lifting, and is built-in, can not be repaired after damage causes the production
Product are not good in practical application effect, and popularization and application also have certain difficulty；In addition, in the information trackability work(that dispatches from the factory of cable
In terms of energy, retained more than the information dispatched from the factory due to cable by units such as manufactory, designing institutees, and its own is not believed
Breath storage, so as to cause its own product information to review.
The content of the invention
In order to solve above-mentioned the deficiencies in the prior art, it is built-in that the purpose of this utility model is to provide a kind of measurement part,
Long-time stability are good, and information of dispatching from the factory can be stored, retrospective intelligent cable fixing nut.
Technical problem to be solved in the utility model is achieved by the following technical programs：A kind of intelligent cable is fixed
Nut, including cable fixing nut body, stress induction device, memory, sensor mounting groove, mechanical hole A, mechanical hole B, its
It is characterised by：This body side surface of the cable fixing nut is provided with sensor mounting groove, and the sensor mounting groove is provided with mechanical hole
A, mechanical hole B, the stress induction device is embedded to be arranged between mechanical hole A and mechanical hole B.
Further, the stress induction device is type vibration wire strain gauge.
Further, the memory be monobus eeprom memory, its model DS2431, capacity is 1Kbit, is adopted
With two-wire system communication mode, the information such as the date of production, production batch number, size can be stored.
Further, the sensor mounting groove length direction is consistent with cable fixing nut axially loaded direction.
Further, the sensor mounting groove is three, is distributed on the cable fixing nut this body side surface.
Further, the sensor mounting groove size is the long 50mm* depth 10mm of width 10mm*.
Further, the mechanical hole A and mechanical hole B is M4 screw holes.
Further, the mechanical hole A and mechanical hole B spacing are 40mm.
The utility model has the advantages that：
The utility model fixes intelligent apparatus and the intelligent cable of cable fixing nut integrated design there is provided a kind of
Nut, i.e., by the embedded design of intelligent apparatus, be installed within cable fixing nut, and do not influenceing cable fixing nut itself
On the premise of structure and size, realize cable fixing nut measurement part and use and dispatch from the factory steadily in the long term the storage of information；Its
With it is simple in construction, manufacture easy for installation, long-time stability it is good, information tracing is strong the features such as.
