Abstract
The utility model relates to the field of bridge stay cables, in particular to a cable body protective device. A stay cable body protective tube is composed of two half tube bodies and sensing optical fibers, wherein the half tube bodies are respectively provided with a convex edge and a concave groove. The two half tube bodies form a protective tube body under the connecting effect of the convex edges and the concave grooves and the sensing optical fibers are evenly distributed on the surface of the protective tube body. The stay cable body protective tube is convenient to disassemble and replace, high in operability and capable of effectively reducing wind-and-rain-induced vibration, and online monitoring of the protective tube can be realized so that problems can be found out timely and remedial measures can be taken.
Description
Technical field
The utility model relates to bridge stay cable field, relates in particular to the protective device of cable body.
Background technology
Stayed-cable bridge has that span is larger, handsome in appearance, easy construction, the feature such as with low cost, is current more common a kind of bridge type.Drag-line is the important component of stayed-cable bridge, and suspension cable bears fatigue loading for a long time, accidental mechanical damage, again in region, rivers bay, often be exposed in the environment of wind and rain, humidity, drag-line easily suffers corrosion failure, and this causes bad consequence to bridge and society.Cable body has Multiple Protective System at present, if but protection system is destroyed, remedies not in time, and steel strand start corrosion degradation, and Suo Li changes, and then affects the total quality of bridge.Cable body on-line monitoring system can be pinpointed the problems in time, and quick solution problem, at utmost to reduce the destruction of cable body.The on-line monitoring that optical fiber sensing technology is cable body provide may, sensor monitoring system combines with computer monitoring, can occur that abnormal situation monitors and report to the police to cable body.In addition, thereby change by changing the shape of cable body protection tube the object that drag-line aerodynamic characteristics can reach inhibition vibration, to reduce the damage of drag-line.Therefore, design a kind of being easy to and remove and install, suppress vibration, the online cable body protection tube detecting, reaches the effect of safeguarding suspension cable safety and stability.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of oblique pulling cable body protection tube.
For addressing the above problem, a kind of oblique pulling cable body protection tube described in the utility model, is comprised of two half body I (3), half body II (4) and sensor fibres (5) that are respectively equipped with fin (1) and groove (2).Two and half body I (3), half body II (4) form protection tube (6) under the connection function of fin (1) and groove (2); Sensor fibre (5) is distributed in described protection tube (6) surface uniformly.
The side pipe wall of described half body I (3) is provided with described fin (1), and two ends are respectively equipped with fin (11) and groove (21), and outer surface of tube wall is provided with equidistant rib muscle (7).
The side pipe wall of described half body II (4) is provided with described groove (2), and two ends are respectively equipped with fin (11) and groove (21), and outer surface of tube wall is provided with equally spaced rib muscle (7).
Described half body I (3), half body II (4) connect as a whole by tube wall skin.
The groove (2) that fin (1) in described half body I (3) inserts in described half body II (4) forms described protection tube (6), and described half body I (3), the half lip-deep rib muscle of body II (4) (7) mutually docking form helix.
Described sensor fibre (5) is wound around bonding formation helical form along described rib muscle (7).
Fin (11) on described protection tube (6) can insert the groove (21) on another root protection tube, and the length of protection tube is extended.
The utility model compared with prior art has the following advantages.
1, the utility model is comprised of two semicanals, by fin, is inserted and is connected with groove, and dismounting and change is convenient, and whole process is easy fast.
2, the utility model two ends can be connected with the insertion of groove by fin and extend protection tube with the two ends of another two protection tubes, have improved operating efficiency.
3, sensor fibre of the present utility model is wrapped on protection tube with helical form, can effectively reduce rain wind induced vibration.
4, sensor fibre of the present utility model can transmit detection signal, realizes the on-line monitoring of protection tube, to pinpoint the problems in time, and enforcing remedies measure.

The specific embodiment
As shown in Figures 1 to 5, a kind of oblique pulling cable body protection tube, is comprised of two half body I 3, half body II 4 and sensor fibres 5 that are respectively equipped with fin 1 and groove 2.During installation; cable body is wrapped in described half body I 3, half body II 4; the groove 2 inserting on half body II 4 side pipe walls by the fin 1 on half body I 3 side pipe walls forms described protection tube 6, and now, outer surface of tube wall equal intervals rib muscle 7 mutually docking forms helix.According to actual conditions, can extend protection tube, the fin 11 on described protection tube 6 can insert the groove 21 on another root protection tube, extensive protection length of tube.Described sensor fibre 5 is wound around bonding formation helical form along described rib muscle 7.When protection tube produces distortion or crack under extraneous mechanical force, there is deformation by part in the sensor fibre passing through therebetween, thereby sensor fibre detection signal is herein changed, and realizes status monitoring.In addition, sensor fibre is wrapped on protection tube with helical form, is a kind of measure that effectively reduces rain wind induced vibration.
