Description
Technical field
The utility model relates to a kind of cable bend equipment, particularly a kind of Cable Bending Radius controller.
Background technology
Along with deepening continuously of city cable, each department power grid cables quantity grows with each passing day, and cable has occupied leading position in electrical network, whether the safety of its operation will directly affect the safe and stable operation of electrical network, so it is too impatient to wait to improve the cable work quality, is the emphasis in the from now on engineering construction.Cable Bending Radius is the important indicator of cable laying construction and its insulation property of assurance in service, if cable in cable laying operation or bending radius in service less than setting, can directly cause its structural damage, directly affect its life-span, finally cause insulation breakdown, lead to the safe mass accident, affect power network safety operation.
1. owing to reasons such as urban planning and left over by history, the cable work well size in many places is generally less, and how reasonable Arrangement cable position and control cables minimum bending radius are a great problems in the engineering construction.
2. because all factors, the now construction of cable work is accepted by cooperation troop, the not high and reason such as be subjected to that economic interests are ordered about owing to cooperation troop ' professional, causing engineering construction often all is only to say progress, do not stress quality, also just cause many safe mass hidden danger, such as: arbitrarily put cable, firmly squeeze cable and enter worker's well, cause to reserve can't meet the demands in the Cable Bending Radius of worker's well etc.
3. the key factor of cable running safety is the good degree of its insulation and the uniformity that internal electric field distributes.Cable Bending Radius is the important indicator that guarantees its insulation property, and too small bending radius is destroyed its internal structure, directly affects its life-span, and severe patient will directly cause insulation breakdown, lead to the safe mass accident.
4. all with range estimation or tape measure etc., the error that this method is brought is larger for traditional measurement cable minimum bending radius method, causes easily erroneous judgement, misjudgement, does not possess science, and do not possess practicality in the engineering construction process.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and provides a kind of simple in structure, easy to use, can guarantee the Cable Bending Radius controller that control cables minimum bending radius at any time can meet the demands.
A kind of Cable Bending Radius controller, its structural feature is: include support bar, bendable rod and stay cord or adjusting rod, be provided with the through hole that passes for bendable rod in an end of support bar, the axis of described through hole is perpendicular to the axis of support bar, axis along support bar on support bar is distributed with scale value, place, support bar both sides at the scale value place is provided with for the jockey that connects stay cord or adjusting rod, be provided with the jockey that stretches for hanging at the both ends of bendable rod, one end of two stay cords or adjusting rod is connected to the jockey place at bendable rod two ends when work, the other end of two stay cords or adjusting rod is connected to the jockey place on the identical graduation value of support bar, and the pulling rope length between bendable rod and the support bar after connecting equals this corresponding scale value of support bar to the length between the bendable rod of support bar.
Cable Bending Radius controller of the present utility model, in use, the needed minimum bending radius of crooked cable is selected stay cord on the Cable Bending Radius controller or the scale value of adjusting rod required correspondence on support bar as required, then an end of stay cord or adjusting rod is connected to the jockey place at scale value place, the other end is guaranteeing that stay cord or adjusting rod are in the jockey place that the jockey at this scale value place of support bar and jockey that the length between the bendable rod is equal to the corresponding scale value of support bar place are connected in variable curved bar two ends after the length of the support bar between the bendable rod, the radian that then utilizes bendable rod compares with crooked good cable, just can see very clearly crooked cable noly reach the minimum sandards requirement.
The jockey that be used for to connect stay cord or adjusting rod on the described support bar is hook or draw ring, and stay cord is tied on hook or the draw ring, and adjusting rod then utilizes the through hole that arranges or hook or draw ring to connect on hook or draw ring thereon.
The jockey that described variable curved bar both ends be used for to hang stay cord or adjusting rod is draw ring or hook or through hole, and stay cord is tied on hook or the draw ring, and adjusting rod then utilizes the through hole that arranges or hook or draw ring to connect on hook or draw ring thereon.
In sum, the utility model following advantage compared to existing technology:
Cable Bending Radius controller of the present utility model can effectively solve cable laying installation quality control problem, and it shows:
(1) with the cable controller cable minimum bending radius is controlled, made cable insulation not impaired, prolong cable service life, improve power network safety operation, also reduce the power grid construction investment simultaneously.
(2) by this controller of long period mandatory requirement site operation librarian use, can cultivate cable construction personnel specification construction custom, promote the cable work quality from the source.
(3) cable minimum bending radius traditional measurement method in work progress is range estimation, otherwise, must after cable is in place, can measure, and this device can when not affecting construction, be controlled bending radius.
(4) this device uses simply, convenient, can supply simultaneously the supervisor of constructions such as owner, management, design to the control that exercises supervision of cable work quality.
(5) all with range estimation or tape measure etc., the error that this method is brought is larger for traditional measurement method, causes easily erroneous judgement, misjudgement, compares with it, and this controller has more science.
