Description
Technical field
The present invention relates to a kind of cable body, especially a kind of Intelligent carbon fiber cable body.
Background technology
In suspension bridge it is lateral opening main push-towing rope is anchored when, main push-towing rope is divided into many stock steel beams difference anchors in anchor ingot, this
A little steel beams are just referred to as anchor cable.
Mainly using steel strand wires as cable body, the weight of steel strand wires compares existing anchor cable, when stretch-draw prestressing force is larger, steel
The weight of twisted wire cable body can be doubled and redoubled, and weight growth can bring a series of problems, and carrying is inconvenient, either transports, also
It is that in-site installation tensioning is all inconvenient.Anchor cable needs to offset a part of gravity of itself after weight growth causes tensioning so that
Stretch-draw effect declines.
And using steel strand wires as cable body, the maximum pull of steel strand wires has its limit value, in order to improve maximum pull, needs
Increase the diameter of steel strand wires, after the diameter increase of steel strand wires, the weight of anchor cable also rises, and then brings a series of problems.
Moreover, cable body is typically all when in use tens meters long, longer meeting extends to rice up to a hundred, this is just to cable body
Monitoring bring inconvenience, at present, there are no a kind of technologies in real time to monitor the working condition of cable body in real time.
The content of the invention
The present invention solves existing anchor cable using steel strand wires as cable body, and weight is bigger, and it is inconvenient that installation is carried, and opens
Needed after drawing offset self gravitation, stretch-draw effect decline the defects of, a kind of Intelligent carbon fiber cable body is provided, is reversed using carbon fiber rod
Cable body is synthesized, and in external coated epoxy resin glue, mitigates the weight of anchor cable, facilitates carrying and installation.
This invention also solves at present cannot whole cable body monitored in real time the defects of, a kind of Intelligent carbon fiber rope is provided
Body reverses synthesis cable body using carbon fiber rod, and carbon fiber rod in-core implantation fiber-optic monitoring sensor passes through fiber-optic monitoring sensor
The working condition of carbon fiber rod can be monitored in real time, and then react the working condition of whole cable body.
The specific technical solution of the present invention is：A kind of Intelligent carbon fiber cable body, the multi-strand carbon fiber stick including spiral twist,
Outside is coated with epoxy resin layer, and the center of at least one carbon fiber rod is implanted with fiber-optic monitoring sensor.Using carbon fiber
Stick spiral torsional synthesizes cable body, mitigates the weight of cable body, facilitates carrying and installation；Carbon fiber rod center implantation fiber-optic monitoring sensing
Device can monitor the working condition of carbon fiber rod in real time by fiber-optic monitoring sensor, and then react the working condition of whole cable body.
Preferably, carbon fiber rod is odd number stock, center is one, and periphery is even number stock.
Preferably, the carbon fiber rod in center has been implanted into fiber-optic monitoring sensor.
Preferably, it is implanted with fiber-optic monitoring sensor in per one carbon fiber rod.
Preferably, the shaft core position of carbon fiber rod is provided with core bore, fiber-optic monitoring sensor is arranged in core bore, core bore
It is interior to be filled with epoxy resin.
Preferably, fiber-optic monitoring sensor includes optical fiber and is placed on the protective case of outer fiber.
Preferably, optical fiber is in the centre of protective case, protective case forms hollow elastic cavity, bullet in optical fiber periphery
Property chamber be four, four 90 ° of elastic cavity intervals.
Preferably, grating formation FBG monitoring sensor is carved at interval on optical fiber.
Preferably, optical fiber end is connected with Guang Nayi.
Preferably, during carbon fiber rod spiral twist, the relative position between carbon fiber rod remains unchanged.
The beneficial effects of the invention are as follows：Cable body is synthesized using carbon fiber rod spiral torsional, mitigates the weight of cable body, facilitates carrying
And installation；Carbon fiber rod center is implanted into fiber-optic monitoring sensor, and carbon fiber rod can be monitored in real time by fiber-optic monitoring sensor
