Then, as shown in Figure 1, unreel the constant steel wire rope G of linear velocity maintenance from right to left, enter and clean water tank 1.Again, (Fig. 2 unreels the constant steel wire rope G of linear velocity maintenance from left to right as Fig. 1, Fig. 2, enter and clean water tank 1) shown in, described cleaning water tank 1 is provided with: the desilt mechanism of dioptric type and the vibration-type secondary desilt mechanism that are used for removing impurity such as clod that steel wire rope is mingled with, sandstone, described desilt mechanism traverses described cleaning water tank 1 laterally to establish, a plurality ofly have the directive wheel or a guiding roller 2 of potential difference up and down, and described vibration-type secondary desilt mechanism is that the water tank of being located at steel wire rope exports a side, impacts vibrator 3 to what the steel wire rope in the motion impacted.The described linear velocity that unreels keeps constant steel wire rope G can remain on usually 500-2000m/ hour by the speed of service of cleaning water tank 1.In the present embodiment, adopt the speed of service of 500-1000m/ hour steel wire rope G more.
Have the directive wheel or the guiding roller 2 of potential difference up and down as a described desilt mechanism of dioptric type that is used for removing impurity such as clod that steel wire rope is mingled with, sandstone a plurality of, steel wire rope to be cleaned is under the guiding of above-mentioned directive wheel or guiding roller, tortuous repeatedly, distortion ground passes through to clean water tank, the silt of caking etc. can be unable to undergo distortion, and falls down.
Once clean in the water tank 1 at heating type, be equipped with six groups in the cleaning case and amount to 18KW heater 5, and be added with the water that liter more than 200 has added extraordinary cleaning, rust cleaning liquid, under the situation of boiling, allow steel wire rope G process, in order to clean greasy dirt and rust cleaning.The water that cleans in the water tank 1 is heated to boiling, quicken silt etc. dispersion, fall, simultaneously, quicken the removal of corrosion, rust staining.
When steel wire rope moves in the cleaning water tank, be arranged at the vibration-type secondary desilt mechanism of cleaning in the water tank, the steel wire rope that promptly impacts in 3 pairs of motions of electromagnetic shaker impacts, described vibration-type secondary desilt mechanism drives a rotating disk by a small machine, and three on the rotating disk impact hammer, hits steel wire rope with the power about 1000--2000N, the speed that adjusting impacts, make to impact the resonant frequency of frequency near steel wire rope, steel wire rope produces judder, thereby dirt is poured in the water.Further silt etc. is removed in vibrations.The described vibration-type secondary desilt mechanism of cleaning in the water tank that is arranged at promptly impacts electromagnetic shaker 3 and can be arranged in the described cleaning water tank any place in the steel wire rope operation way.In the present embodiment, be arranged at the section start of steel wire rope operation in the described cleaning water tank.
In cleaning water tank 1, screen pack 8 is installed, with filtered water, guide to the nearly exit of water tank, by in three plastic spout 4 (using on the lathe) above the water surface, with the pressure of 0.4-0.6Mpa, with 4-6m per hour with a pump
3Speed, eject.When steel wire rope from this by the time, the sewage that is attached to the steel wire rope surface is washed away.
Steel wire rope after flushing, (no longer drips) behind the substantially dry by heated-air drying in the water tank exit, enters subsequent processing.
In the Non-Destructive Testing part 9 of subsequent processing, the Non-Destructive Testing operation adopts weak magnetic carrying out flaw detection instrument.Described weak magnetic carrying out flaw detection instrument partly is made of weak magnetic loading section, test section and computer.
Secondly, Non-Destructive Testing part 9 is used for quantitatively measuring the Non-Destructive Testing of fracture of wire, corrosion, wearing and tearing and the degree of fatigue of the steel wire rope through cleaning.The described part 10 that oils is used for the steel wire rope outer surface through cleaning, detecting is applied antirust oil.
Native system has adopted contemporary state-of-the-art weak magnetic carrying out flaw detection instrument, can be under motion state, do not damage steel wire rope, just steel wire rope being made overall process detects, can quantitatively measure fracture of wire, corrosion, wearing and tearing and the fatigue of steel wire rope, and, the steel wire rope of this detection is made whether qualified conclusion, and various suggestions according to predetermined use standard.
The weak magnetic carrying out flaw detection instrument of this instrument divides three parts, and division is as follows:
Weak magnetic loading section:
Be installed in the cleaning case exit, after the energising, can produce more weak magnetic field, magnetize for the steel wire rope that therefrom passes through.Because magnetic field is very weak, so the remnant field on steel wire rope surface is also very weak, and low-intensity magnetic field is stable fine, is not easy decay, and magnetic a little less than therefore once loading can guarantee need not reload in three months.
The test section:
The major part of native system, utilize the new theory of " space magnetic field vector composition principle ", add a counter magnetic field earlier, and demarcated, the magnetic field that original weak magnetic and space stray magnetic field and ferromagnetic material are on every side produced is all offset and is " zero ", steel wire rope changes original weak magnetic if the fracture of wire equivalent damage is arranged at this moment, and this variable quantity is just outstanding.Use " Dou Shi element " again, a kind ofly will exceed tens thousand of times high sensitive sensor, detect the variation in this magnetic field, again through calculating the various losses of quantitatively measuring steel wire rope than the sensitivity of traditional Hall element.
Computer: every volume steel wire rope detects and finishes; detected all data-storings are got up, and can watch this steel wire rope all instant curve and data when detecting in real time, if any great damage meeting instant alarming; standard is scrapped in more serious arrival, but also hard stop.Print on request at last and detect form, use as filing.
According to the cannot-harm-detection device and the method for embodiment 1, detection speed is at 0-30m/s, and detection range is at Φ 1--Φ 26mm, with measured object surface maximal clearance: 30mm.
The detection index of this detection system is as follows:
The quantitative uncertainty of judging:＜0.05%,
A recall rate:＞98%,
Detect repetitive rate:＞98%,
Quantitative accuracy rate:＞95%,
The impaired loci axial error:＜± 10mm.
Promptly detect qualified steel wire rope through above-mentioned operation and enter the part 10 that oils,, avoid corroding in order to the protection steel wire rope to be coated with one deck antirust oil at outer surface.The part that oils adopts immersion, also is that steel wire rope is immersed in the oil, and passes by in oil, and oil just gos deep into playing the purpose that oils in the slit of steel wire rope automatically like this.
During the preparation of this equipment, through investigation, adopt extraordinary antirust oil, the antirust oil of above-mentioned use should have following characteristics: viscosity is low, and good fluidity is easy to attached to the steel wire rope surface.So, then because viscosity and water are similar, so the back that oils is very thin at the oil film that the steel wire rope surface forms, about 1-4 μ, thereby the actual amount of oil is seldom.And viscosity does not almost change, so just need not heat yet and can normally oil in the winter of cold along with variation of temperature.In addition, require this antirust oil to also have passivation, so its rust-proof effect is more far better than general antirust oil, and is convenient to operation.
In the present embodiment, rolling principle, method and the device thereof of rolling part 11B is similar to and unreels part 11A, but its reverse movement, that is, along with the progressively increase of winding radius, angular speed will lower thereupon, keeps permanent tension force and constant linear velocity.Because rolling requires higher to permanent tension force, the three-position type detector when therefore unreeling just can not use, this equipment is below the export orientation assembly that oils, and the high-sensitive pressure sensor that is used for weighing apparatus has been installed, because the variation of winding radius, cause the variation of linear velocity, thereby cause the variation of tension force, the variation that this is very small, pressure sensor can both detect, and export the corresponding signal of telecommunication, remove the control of conversion motor, adjust rotating speed, reach the purpose that keeps permanent tension force.
Have again, neat substantially on the rolling frame for making wire rope roll, before the rolling frame, also adorned bus cable device, this bus cable device is a glass pulley 24.As shown in Figure 4, when steel wire rope was being pressed glass pulley 24 motions, glass pulley can rotate on winding displacement wheel shaft 25, and the guiding trench culture axially-movable on axle 25.When this directive wheel arrives end points, can be along the spirally-guided trench culture counter motion of other direction.Because the bidirectional-movement of this directive wheel on axle, make steel wire rope be wound up on the pedestal relatively more neat.
Because each steel wire rope pedestal, add the weight of steel wire rope, reach more than 1 ton nearly 2 tons.Therefore when pedestal loads and unloads, do lifting with the helical screw jacking device.Unreel and the rolling part, each has adorned the lift of 10 tons of lifting powers, can distinguish lifting.
In the present embodiment, control section adopts a PC cyclelog (not shown), and as the cardiac component of complete equipment, and touch display screen is interactive display platform (not shown) and real-time output input device.In case on touch-screen, set the specification and the speed that are cleaned steel wire rope, as long as press start button, fully automatic operation then.In case have fault or steel wire rope to damage too much, all can report to the police even automatic stopping.
According to the maintaining device of anti-winding steel wire for engineering of the present invention, it cleans water tank length can be in 1-3m length, about about 10 square metres of whole plant area.
Maintaining device and maintenance methods according to anti-winding steel wire for engineering of the present invention, can the Weaving type anti-winding steel wire that not reach the condition of scrapping and useful life as yet be carried out efficient, timely, serial cleaning, detects and oil, thus, not only can reduce the incidence of the production safety accident that described impaired anti-winding steel wire for engineering causes because of fracture of wire etc. greatly, and can increase substantially the service efficiency and the service life of Weaving type anti-winding steel wire, reach two times its service life more in the past.In addition, the maintaining apparatus and method of anti-winding steel wire for engineering of the present invention be a kind of anti-winding steel wire for engineering cleaning, integrated device and method thereof detect, oil, thus, the maintaining cost and the engineering management cost of steel wire rope have also been reduced significantly.
