Abstract
The utility model relates to an intelligent cable of a built-in sensor, which comprises a cable body. The utility model is characterized in that a wire intelligent rib (3) is additionally arranged at the periphery of a wire beam of the cable body; the wire intelligent rib (3) comprises a wire (2) and a fiber grating stain sensor (1); the fiber grating stain sensor (1) comprises a supporting seat (1-4); and the supporting seat (1-4) of the fiber grating stain sensor (1) and the wire (2) are welded together to make the wire intelligent rib (3) capable of testing force. By arranging the wire intelligent rib (3) in the intelligent cable, the output of the built-in sensor can effectively represent the total stress condition of the intelligent cable thereby ensuring the requirement of the long-term reliability and stability of the built-in sensor for testing cable force.
Description
Technical field
The utility model relates to a kind of intelligent cable of built-in sensors, is applicable to cable load-carrying members such as cable stayed bridge, suspension bridge, arch bridge.Also can be applicable to fields such as traffic, automobile, building.Belong to bridge construction part technical field.
Background technology
The funicular system of modern Longspan Bridge is the core component of cable stayed bridge and suspension bridge, dynamic load on the deadweight of long-span bridge girder construction and the bridge, the overwhelming majority is to be delivered on the king-post by funicular system, and the duty of cable is directly to reflect one of important symbol whether bridge is in a safe condition.But owing to reasons such as structure design, environmental corrosion, fatigue accumulations, damage and deterioration in various degree appears in cable in-service unavoidably.If sensor organically can be integrated into cable inside, make and himself can measure parameters such as internal stress, temperature, make its cable rise to intelligent cable with automatic perception from a simple load, also realize taking into account the possibility of the whole stressed of cable and the stressed monitoring of local silk simultaneously, to more help structural safety and the operation state that people grasp cable self and full-bridge, the tendency of discovery accident in time, prevent that sudden accident from taking place.
Fiber grating is a kind of sensing element of function admirable, can respond to extraneous small strain by moving of bragg reflection wavelength and change, thereby realize parameters such as structural stress, temperature are realized on-line monitoring.It has the adverse circumstances of not being afraid of, be not subjected to ambient noise interference, anti-electromagnetic interference, collection sensing be transmitted in characteristics such as one, simple structure, easy to use, certainty of measurement height.
Application number is that application for a patent for invention that 200910145152.X, name are called " bridge intelligent cable system of built-in fiber grating sensor " discloses fiber grating is made fiber Bragg grating strain sensor with suitable encapsulating structure, and it is arranged in cable connecting cylinder position, but make the intelligent cable of inside dynamometry.Application number is 200910145153.4, the application for a patent for invention of title " intelligent cable fiber grating strain sensor " discloses the encapsulating structure of special fiber Bragg grating strain sensor.Make the cable built-in sensor can test the stressing conditions of steel wire in the rope exactly, need the high tensile steel wire that special fiber Bragg grating strain sensor and cable is interior effectively to be connected.Because the safe handling requirement of high tensile steel wire in the cable, any operation that influences its intensity can not be carried out in the surface.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of can be under the prerequisite that does not influence other steel wires, make the output of sensor can reflect the intelligent cable of built-in sensors of the whole force-bearing situation of cable.
The purpose of this utility model is achieved in that a kind of intelligent cable of built-in sensors, comprise cable body, be added with steel wire intelligence muscle in the steel tendon periphery of described cable body, this steel wire intelligence muscle comprises steel wire and fiber Bragg grating strain sensor, fiber Bragg grating strain sensor comprises bearing, the bearing and the steel wire welded of described fiber Bragg grating strain sensor are connected together, but make the steel wire intelligence muscle of dynamometry.
The beneficial effects of the utility model are:
The utility model makes the output of built-in strain transducer can effectively characterize the whole force-bearing situation of cable by arrange steel wire intelligence muscle in cable.The long-term reliability of cable built-in sensor test Suo Li, the requirement of stability have been guaranteed.
