It is a kind of for controlling the device of Cable Bending Radius, including two range finders, one of range finder is for emitting
Distance measuring signal, for another range finder for receiving distance measuring signal, two range finders are respectively provided at the both ends of arc cable to be measured, survey
It is equipped with Elastic buckle away from device, range finder includes that pedestal and the signal element for emitting or receiving signal, pedestal are fixed on bullet
Property buckle top, signal element is rotatably arranged on pedestal.
Preferably, the Elastic buckle is equipped with the notch for being caught in arc cable to be measured.Elastic buckle can be very
It is easily stuck on cable, the position of fixed range finder.
Preferably, the Elastic buckle is arc-shaped, the inner ring of Elastic buckle and the outer ring of cable match.Elastic buckle
The stabilization that cable is conducive to range finder is encircled, and passes through the angle of the rotation adjustable range finder of Elastic buckle.
Preferably, the range finder is equipped with alarm, alarm is less than minimum bend half for Cable Bending Radius
Alarm sound is issued when diameter.When cable overbending, alarm issues alarm sound, reminds construction personnel that adjustment is needed to apply
Work.
The beneficial effects of the utility model are: after the arc length and minimum bending radius of (1) acquisition arc cable to be measured, according to
Formula scales can obtain the minimum linear distance of arc cable ends to be measured, and range finder can measure arc cable ends to be measured

Specific embodiment
The utility model is further described in the following with reference to the drawings and specific embodiments.
It is a kind of for controlling the device of Cable Bending Radius as shown in Fig. 1 to Fig. 2, including
It is a kind of for controlling the device of Cable Bending Radius, including two range finders 1, one of range finder is for emitting
Distance measuring signal, for another range finder for receiving distance measuring signal, two range finders are respectively provided at the both ends of arc cable 2 to be measured.
Range finder is equipped with Elastic buckle 3, and Elastic buckle is equipped with notch 4 for being caught in arc cable to be measured, and Elastic buckle can be with
It is easily stuck on cable, the position of fixed range finder.Elastic buckle is arc-shaped, the inner ring of Elastic buckle and the outer ring of cable
Match, Elastic buckle encircles the stabilization that cable is conducive to range finder, and passes through the rotation adjustable range finder of Elastic buckle
Angle.The range finder includes pedestal 11 and the signal element 12 for emitting or receiving signal, and pedestal is fixed on Elastic buckle
Top, signal element is rotatably arranged on pedestal, and signal element can rotate on the base, facilitates adjustment receiving angle or transmitting
Angle accurately obtains the linear distance of arc cable to be measured.Range finder is equipped with alarm 13, and alarm is for cable bend half
Diameter issues alarm sound when being less than minimum bending radius, and when cable overbending, alarm issues alarm sound, reminds construction
Personnel need to adjust construction.
Specific step is as follows when the utility model is used:
Step 1 determines the minimum bending radius r of arc cable to be measured according to relevant regulations according to the type of cable；Electricity
Relationship between the minimum bending radius of cable and outer diameter has corresponding requirement according to type of cable, single or multicore, with
