Abstract
The utility model provides a steel rope harmless flaw detector which is composed of steel rope, a length measuring device, a left signal pick device and a right signal pick device. The left signal pick device and the right signal pick device are arranged together, a hollow cavity is formed between the signal pick devices, and the steel cable penetrates into the hollow cavity; the length measuring device is fixed at the end of the left signal pick device, and the distance measuring wheel of the length measuring device is connected with the steel cable. The steel rope harmless flaw detector has the characteristics of reasonable design, simple structure, convenient operation, small size, light weight, convenient operation, etc., and the utility model is a necessary detecting instrument for the inclined pulling type bridge steel rope and steel ropes in other industries.
Description
The utility model relates to a kind of surveying instrument, specifically a kind of cable wire harmless flaw detector.
Cable wire is except generally using in hoisting device, be exactly in bridge construction, generally to use, as having built up in the world and the cable wire cable-stayed bridge of in use various scales has several thousand, cable wire cable-stayed bridge that China has used or just under construction also has more than 100, these bridges build up the effect important to the development of the national economy play more and more of various countries, but prolongation along with cable wire cable-stayed bridge term of life, excoriate in the cable wire between steel wire, the unsafe factor that the reasons such as collision deformation of corrosion fracture of wire and traffic hazard can cause is with increasing, more and more obvious, existing at present bridge cable wire is because of the unsafe factor of failing in time to detect above-mentioned existence cause the breaking generation of rope accident.The prolongation of disconnected rope accident except above-mentioned term of life takes place, excoriate in the cable wire between steel wire, outside the reasons such as collision deformation of corrosion fracture of wire and traffic hazard, the material that also has cable wire, design strength, the crudy of cable wire etc. all can influence the serviceable life of cable wire, the specialized equipment or the instrument that detect cable wire are not also arranged at present, carry out system's detection before can't accomplishing use, regularly detect in the use, in time pinpoint the problems and in time handle, and the term of life of accurately measuring cable wire is carried out autotelic replacing, depend merely on the definite cable wire of the estimation method in serviceable life now to change, to reduce the waste of cable wire, prolong the replacement cycle of cable wire, reduce the use cost of bridge.
The purpose of this utility model provides a kind of system that carries out before cable wire is used and regularly detects in detecting, using, and can accurately measure the cable wire harmless flaw detector that the term of life of cable wire has purpose that cable wire is changed.
The purpose of this utility model realizes in the following manner, make two magnetic saturation signal pickups with magnet steel and coil, detected cable wire pass in the middle of two magnetic saturation signal pickups be magnetized saturated, the change of cable wire sectional area can cause the change of magnetic flux, coil becomes flux change into electric signal, electric signal machine is as calculated handled the fracture of wire that just obtains every whole piece cable wire, corrosion, the full detail of defectives such as wearing and tearing, the detection information of these information datas and the standard specimen cable wire of sealing up for safekeeping is compared analysis, thereby can obtain the various important technology data of cable wire, accurately to extrapolate the safe operating life of cable wire.
Accompanying drawing 1 is the structural representation of cable wire harmless flaw detector;
Accompanying drawing 2 is the end face structure synoptic diagram of cable wire harmless flaw detector.
Explain below with reference to Figure of description cable wire harmless flaw detector of the present utility model being done.
Cable wire harmless flaw detector of the present utility model, its structure is to be made of cable wire 1, device for measuring length 2, left signal pick-up 3 and right signal pick-up 4, left signal pick-up 3 and right signal pick-up 4 are also together, one cavity is arranged between the two, cable wire 1 is through among the cavity, device for measuring length 2 is fixed on the end of left signal pick-up 3, and its range finding wheel 5 and cable wire 1 join.
The left signal pick-up of this cable wire harmless flaw detector and right signal are lifted and got device is to be made of half rounds noose tube 6, pole shoe 7, magnet steel 8, magnetic conductive board 9 and coil 10, coil 10 is around the centre of magnetic conductive board 9, and pole shoe 7 and magnet steel 8 are fixed between the two ends of magnetic conductive board 9 and half rounds noose tube 6 from inside to outside.
Embodiment:
Its processing and fabricating of cable wire harmless flaw detector of the present utility model is very simple and convenient, making the left signal pick-up that can combine of two symmetries and right signal with cable wire sleeve, pole shoe, magnet steel, magnetic conductive board and coil shown in the by specification accompanying drawing lifts and gets device, coil is around the centre of magnetic conductive board, pole shoe and magnet steel are fixed between the two ends of magnetic conductive board and cable wire sleeve from inside to outside, and cable wire passes in the middle of the cable wire sleeve.Detecting the length of cable wire when using is measured by device for measuring length, the flux change signal that cable wire is produced between left signal pick-up and right signal pick-up is gone out electric signal and is sent into Computer Analysis and handle by coil-induced, and the inherent quality result of variations of cable wire is read on display.
Cable wire harmless flaw detector of the present utility model is compared with prior art, have reasonable in design, simple in structure, be easy to processing, volume is little, in light weight, easy to use, detect characteristics such as accurate, it is modern cable-stayed type bridge cable wire and other industries indispensable detecting instrument with cable wire, thereby, have good value for applications.
Except that the described technical characterictic of instructions, be the known technology of those skilled in the art.
