Description
Technical field
The utility model relates to a kind of monitoring device, especially a kind of cord clip slides monitoring device.
Background technique
For suspension bridge in hanging beam and in bridge operational process, the cord clip on main push-towing rope subjects various alternating load punchings
It hits, although cord clip fastening bolt guarantees fastening force and frictional force using jack tension, after a period of time has passed, still
It will appear bolt looseness, cord clip generates the phenomenon that sliding, there is very big security risk！Present inspection is using manual inspection
Method, time-consuming and laborious, there are many human factor.And data not can be traced.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of cord clip sliding monitoring device, can be in rope
Press from both sides offset deviation amount exceed setting value when, issue monitoring, alarming signal, can in time, effectively monitor cord clip slippage and and
Alarm.The technical solution adopted in the utility model is:
A kind of cord clip sliding monitoring device, comprising: cable fixture, fixed plate, fiber-optic grating sensor, axle sleeve；
The cable fixture is mounted on main push-towing rope, below the cord clip monitored on main push-towing rope, is separated by with cord clip lower end surface
One distance；
The mounting plate on cable fixture；Fiber-optic grating sensor is fixed in fixed plate；Fiber-optic grating sensor
Contact is towards cord clip lower end surface direction；
The contact of fiber-optic grating sensor forms monitoring channel by the lower end face contact after axle sleeve protection with cord clip.
Further, fiber-optic grating sensor connects (FBG) demodulator by optical fiber.
Further, cable fixture includes two semicircular rings, and described two semicircular rings are mounted on main push-towing rope by fixing bolt
On.
Further, fiber-optic grating sensor is fixed by screw and fixed plate.
Utility model has the advantages that
1) cord clip slippage and and alarm can in time, effectively be monitored.
2) it avoids erroneous judgement caused by human factor and leaks prison phenomenon.
3) it is provided a strong guarantee at the operation monitoring after bridge, monitoring data record in real time, can be traced.
4) it has high economic benefit and safety benefit.
Detailed description of the invention
Fig. 1 is the structure composition schematic diagram of the utility model.
Fig. 2 is the side schematic view of the utility model.
Specific embodiment
Below with reference to specific drawings and examples, the utility model is described in further detail.
As shown in Figure 1, cord clip 1 realizes that position is fixed using fastening bolt 2 and main push-towing rope 3；As the main push-towing rope 3 of bridge, due to
Gravity factor is in downward parabolic curved state among it；Sunpender upper end connects cord clip 1, and downrod lower end connects the steel case of bridge
Beam；Since cord clip 1 is loosened, cord clip 1 by the downward pulling force of sunpender after use after a period of time if there is fastening bolt 2
It may be slid downwards along main push-towing rope 3；
The utility model proposes a kind of cord clip slide monitoring device, including two semicircular rings 4,5, it is fixing bolt 6, fixed
Plate 7, fiber-optic grating sensor 8, axle sleeve 9；
Described two semicircular rings 4,5 are mounted on main push-towing rope 3 by fixing bolt 6, the cord clip 1 monitored on main push-towing rope 3
Lower section is separated by a distance with 1 lower end surface of cord clip；
Plate 7 is welded and fixed in a semicircular ring 5 wherein；Fiber-optic grating sensor 8 is solid by screw 701 and fixed plate 7
It is fixed；The contact of fiber-optic grating sensor 8 is towards 1 lower end surface direction of cord clip；
The contact of fiber-optic grating sensor 8 forms monitoring channel by the lower end face contact after the protection of axle sleeve 9 with cord clip 1；
Fiber-optic grating sensor 8 connects (FBG) demodulator by optical fiber；
Maximum displacement departure that mounting distance between cord clip 1 and semicircular ring is allowed by cord clip 1 is determined；When cord clip 1
When moving departure beyond setting value, fiber-optic grating sensor 8 is touched by axle sleeve 9, then monitoring is reported after demodulating by (FBG) demodulator
Alert signal is transferred to control centre, to effectively realize monitoring control.Control centre can record monitoring data.
Fiber-optic grating sensor 8 transmits signal by light, has and easily realizes digitlization, precision height, strong antijamming capability, do not have
Have the advantages that artificial error in reading, it is easy for installation, using reliable.It needs to power using other displacement detecting sensors, in main push-towing rope
Upper power supply has difficulties, therefore the fiber-optic grating sensor for not needing power supply is suitble to use in the environment of the utility model.
It should be noted last that the above specific embodiment is only to illustrate the technical solution of the utility model rather than limits
System, although the utility model is described in detail referring to example, those skilled in the art should understand that, it can be right
The technical solution of the utility model is modified or replaced equivalently, without departing from the spirit and model of technical solutions of the utility model
It encloses, should all cover in the scope of the claims of the utility model.
