Description
Technical field
The present invention relates to a kind of cable bending apparatus, particularly a kind of Cable Bending Radius controller and cable bending method.
Background technology
Along with deepening continuously of city cableization, 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 engineering construction from now on.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 influence its life-span, finally cause insulation breakdown; Lead to the safe mass accident, influence power network safety operation.
1. owing to reasons such as urban planning and left over by history, the cable worker well size in many places is generally less, and how reasonable Arrangement cable position and control cable minimum bending radius are a great problems in the engineering construction.
2. because all factors; The construction of cable work is now accepted by cooperation troop, the not high and reason such as receive that economic interests are ordered about owing to the cooperation personnel of troop professional qualities, and 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, squeeze cable firmly and go into Gong Jing, 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 influences 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 bigger for traditional measurement cable minimum bending radius method, causes erroneous judgement, misjudgement easily, does not possess science, and in the engineering construction process, does not possess practicality.
Summary of the invention
The objective of the invention is to overcome the weak point of prior art, and provide a kind of simple in structure, easy to use, can guarantee the Cable Bending Radius controller that control cable minimum bending radius at any time can meet the demands.
Another object of the present invention also is to provide a kind of cable bending method.
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 supplies bendable rod to pass in an end of support bar; The axis normal of described through hole is in 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 the jockey that is used to connect stay cord or adjusting rod, is provided with the jockey that is used to hang stretching at the both ends of bendable rod, and 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 invention; In use; The stay cord on the needed minimum bending radius selection of the crooked as required cable Cable Bending Radius controller or the scale value of adjusting rod required correspondence on support bar; 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 minimum sandards requirement that cable does not reach.
The jockey that is used 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 is provided with or hook or draw ring to connect on hook or draw ring above that.
The jockey that described variable curved bar both ends are used 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 is provided with or hook or draw ring to connect on hook or draw ring above that.
Cable bending method of the present invention; The stay cord on the needed minimum bending radius selection of the crooked at first as required cable Cable Bending Radius controller or the scale value of adjusting rod required correspondence on support bar; 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 draw ring or the length between hook and the bendable rod that stay cord or adjusting rod are in this scale value place of support bar connect the jockey place in the bendable rod end when being equal to the draw ring at the corresponding scale value of support bar place or hooking into 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 minimum sandards requirement that cable does not reach.
In sum, the present invention compares the following advantage of prior art:
Cable Bending Radius controller of the present invention and cable bending method 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) use this controller through long period mandatory requirement site operation personnel, 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 treat that cable can measure after in place, and this device can be controlled to bending radius when not influencing construction.
(4) this device uses simply, convenient, can supply supervisor of constructions such as owner, management, design to the control that exercises supervision of cable work quality simultaneously.
