Description

A kind of Cable Bending Radius control method
Technical field
The present invention relates to a kind of cable bend equipment, particularly a kind of Cable Bending Radius controller and Cable Bending Radius Control method.
Background technology
With deepening continuously for city cable, each department power grid cables quantity is growing day by day, and cable is occupied in power network Leading position, its whether safe safe and stable operation that will directly affect power network run, so, improve cable work quality It is too impatient to wait, it is the emphasis in engineering construction from now on.Cable Bending Radius is cable laying construction and ensures that its insulate in running The important indicator of performance, if cable bending radius in cable laying operation or operation is less than setting, can directly result in its structure Destruction, directly affect its life-span, finally cause insulation breakdown, lead to safe mass accident, influence power network safety operation.
1. due to reasons such as urban planning and left over by history, many local cable work well sizes are universal smaller how Reasonable Arrangement cable position simultaneously controls cable minimum bending radius, is a great problem in engineering construction.
2. due to a variety of factors, the construction of present cable work is accepted by cooperation troop, due to cooperation personnel's industry Business quality is not high and the reason such as is driven by economic interests, and it is all often only to say progress, do not stress quality to cause engineering construction, is also just made Into many safe mass hidden danger, such as:Cable arbitrarily is put, firmly crowded cable enters work well, causes and reserves in the cable bend of work well Radius can not meet requirement etc..
3. the key factor of cable running safety is the good degree of its insulation and the uniformity of internal electric field distribution.Cable Bending radius is the important indicator for ensureing its insulating properties, and too small bending radius destroys its internal structure, directly affects its longevity Life, severe patient will result directly in insulation breakdown, lead to safe mass accident.
4. traditional measurement cable minimum bending radius method uses range estimation or tape measure etc., the error that this method is brought is larger, holds Easily cause erroneous judgement, misjudge, do not possess science, and do not possess in construction process practicality.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art part, and provide a kind of simple in construction, easy to use, It can ensure that control cable minimum bending radius can meet the Cable Bending Radius controller of requirement at any time.
Another object of the present invention also resides in a kind of Cable Bending Radius control method of offer.
A kind of Cable Bending Radius controller, its structural feature is:Include support bar, bendable rod and drawstring or tune Pole, is provided with the through hole passed through for bendable rod in the one end of support bar, and the axis of described through hole is perpendicular to support bar Axis, scale value is distributed with along the axis of support bar on support bar, is provided with the support bar both sides at scale value For connection stay cord or the attachment means of adjusting rod, the connection dress for hanging stretching is provided with the both ends of bendable rod Put, operationally one end of two drawstrings or adjusting rod is connected at the attachment means at bendable rod two ends, two drawstrings or tune The other end of pole is connected at the attachment means in the identical graduation value of support bar, is located at bendable rod after connecting Pulling rope length between support bar is equal to the support bar corresponding scale value to the length between the bendable rod of support bar.
The Cable Bending Radius controller of the present invention, it is when in use, minimum curved required for the cable bent as needed Drawstring or adjusting rod corresponding scale value needed on support bar on bilge radius selection Cable Bending Radius controller, then will One end of drawstring or adjusting rod is connected at the attachment means at scale value, and the other end is ensureing drawstring or adjusting rod in support The length between attachment means and bendable rod at the bar scale value is equal to the attachment means at the corresponding scale value of support bar It is connected to after to the length of the support bar between bendable rod at the attachment means at variable curved bar two ends, then utilizes bendable rod Radian contrasted with the cable that has bent, so that it may what is be apparent from sees that bent cable institute is no and reaches that minimum sandards will Ask.
It is hook or draw ring to be used for the attachment means of connection stay cord or adjusting rod on described support bar, and drawstring is tied to hook Or on draw ring, and adjusting rod then utilizes the through hole set thereon or hook or draw ring to be coupled with hook or draw ring.
Described variable curved bar both ends are used to hang the attachment means of drawstring or adjusting rod for draw ring or hook or through hole, Drawstring is tied on hook or draw ring, and adjusting rod then utilizes the through hole set thereon or hook or draw ring to be coupled with hook Or on draw ring.
The Cable Bending Radius control method of the present invention, the minimum bend half required for the cable bent as needed first Drawstring or adjusting rod corresponding scale value needed on support bar on footpath selection Cable Bending Radius controller, then by drawstring Or one end of adjusting rod is connected at the attachment means at scale value, the other end is ensureing that drawstring or adjusting rod should in support bar The length between draw ring or hook and bendable rod at scale value is equal to draw ring or hook at the corresponding scale value of support bar To the support bar between bendable rod length when be coupled with the attachment means of bendable rod end, then utilize bendable The radian of curved bar is contrasted with the cable bent, so that it may which what is be apparent from sees that bent cable institute is no and reach minimum sandards It is required that.
In summary, present invention advantage following compared with prior art:
The Cable Bending Radius controller and Cable Bending Radius control method of the present invention, can effectively solve cable laying peace Packing quality control problem, it shows:
(1)Cable minimum bending radius is controlled with cable controller, cable insulation is not damaged, extension cable fortune In the row life-span, power network safety operation is improved, while also reducing power grid construction investment.
(2)The site operation librarian use controller is Qiang Zhiyaoqiud by long period, cable construction personnel specification can be cultivated Construction custom, lifts cable work quality from source.
(3)Cable minimum bending radius traditional measurement method in work progress is range estimation, otherwise, must be after cable is in place It can measure, and the device can be controlled while construction is not influenceed to bending radius.
(4)The device can supply the supervisor of constructions such as owner, management, design simultaneously to cable work using simple, convenient Quality exercises supervision control.
(5)Traditional measurement method uses range estimation or tape measure etc., and the error that this method is brought is larger, easily causes erroneous judgement, misjudgement, In contrast, the controller is more scientific.
