At first, by elevator 21 steel rope spool to be cleaned, that oil, detect processing is promoted to the said service platform that unreels structure.Then, drive by the said variable-frequency motor that is used to control the speed of unreeling that unreels the structure setting and unreel steel rope.
As shown in Figure 3, for unreeling linear velocity, control keeps constant, and unreel structure 1 and be provided with lever-type sender 11 and unreel structure and comprise lever-type sender 11 and bobbin winder bracket 14; Lever-type sender 11 is arranged on the upper end of bobbin winder bracket 14; Described lever-type sender comprises front jocket wheel 15, tension wheel 16, back guide wheel 17 and balance block 19; Be provided with rotating shaft 18 at bobbin winder bracket 14 middle parts; Tension wheel 16 is fixed in the rotating shaft 18 with balance block 19, and the top of tension wheel 16 is connected with front jocket wheel 15, and the bottom of tension wheel 16 is connected with back guide wheel 17; Described tension wheel 16 is horizontal with balance block 19.Arrow vows that tension wheel and equilibrium arm all are contained in the rotating shaft for steel rope G moves towards signal among the figure, if tension force is about value; Then tension wheel 15 is in the basic horizontal position with balance block 18, and like then tension wheel 15 risings of tension force decline steel rope pine, and equilibrium arm 18 descends; And overtension, otherwise then.Survey this three predetermined location near switch with three, and letter is feeds back to the frequency modulation control device; Thereby regulate the speed of variable-frequency motor, tension force decline then unreels cireular frequency slows down, otherwise then increases; When equilibrium arm is horizontal, then keep motor speed constant.
Then,, unreel the constant steel rope of linear velocity maintenance from right to left, get into and clean water tank 1 like Fig. 1 and shown in Figure 2.Said cleaning water tank 1 is provided with: the desilt mechanism of dioptric type that is used for removing impurity such as clod that steel rope is mingled with, sandstone traverses that said cleaning water tank is a plurality of longitudinally to have the track adjusting wheel or a guiding roller 2 of potential difference up and down, and said vibration-type secondary desilt mechanism is the pounder 3 that the water tank of being located at steel rope exports a side, the steel rope in the motion is impacted.Outlet cleaning water tank 1 is provided with tank entry guide rollers 6, and the water tank exit is provided with water tank outlet guide rollers 7, and the lower end is provided with sewage draining exit w.
Said desilt mechanism of dioptric type that is used for removing impurity such as clod that steel rope is mingled with, sandstone be traverse said cleaning water tank laterally, promptly, perpendicular to the sense of motion setting of cleaning steel rope in the water tank, a plurality ofly have the track adjusting wheel or a roller that leads of potential difference up and down; Steel rope to be cleaned is under the guiding of above-mentioned track adjusting 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 heated type, be equipped with six groups in the cleaning case and amount to 18KW temperature booster 5, and be added with the water that liter more than 200 has added extraordinary cleaning, rust cleaning liquid, its liquid level Y under the situation of boiling, lets the steel rope process, in order to clean greasy dirt and rust cleaning.The water that cleans in the water tank is heated to boiling, quicken silt etc. dispersion, fall, simultaneously, quicken the removal of corrosion, rust staining.
When steel rope moves to cleaning water tank end, be arranged at the vibration-type secondary desilt mechanism at this place, i.e. steel rope in 3 pairs of motions of pounder impacts; Said vibration-type secondary desilt mechanism drives a rotating disk by a small machine, and three on the rotating disk impact hammer, hits steel rope with the power about 1000--2000N; The speed that adjusting impacts; Make to impact the resonance frequency of frequency near steel rope, steel rope produces severe jolt, thereby dirt is poured in the water.Further silt etc. is removed in vibrations.
In cleaning water tank 1, filtering net is installed, through the water that filters, guide to the nearly exit of water tank, through what on the spout lathe of three plastics eductors 4 above the water surface, use, with the pressure of 0.4-0.6Mpa, with 4-6m per hour with a pump
3Speed, eject.When steel rope passes through from ring, the sewage that is attached to the steel rope surface is washed away.
Steel rope after flushing, no longer drips behind the substantially dry through heated-air drying in the water tank exit, gets into subsequent processing.
The non-destructive test operation of subsequent processing adopts weak magnetic carrying out flaw detection appearance.Said weak magnetic carrying out flaw detection appearance partly is made up of weak magnetic loading section, test section and computing machine.
Secondly, non-destructive test part 9 is used for quantitatively measuring the non-destructive test through fracture of wire, corrosion, wearing and tearing and the degree of fatigue of the steel rope that cleans.The said part that oils is used for apply anti-corrosion oil through the steel rope outside face that cleans, detects.
Native system has adopted contemporary state-of-the-art weak magnetic carrying out flaw detection appearance; Can under state of kinematic motion, not damage steel rope, just steel rope is made overall process and detect; Can quantitatively measure fracture of wire, corrosion, wearing and tearing and the fatigue of steel rope; And, the steel rope of this detection is made whether qualified conclusion, and various suggestions according to predetermined use standard.
The weak magnetic carrying out flaw detection appearance of this instrument divides three parts, and division is following:
Weak magnetic loading section:
Be installed in the cleaning case exit, after the energising, can produce more weak magnetic field, magnetize for the steel rope that therefrom passes through.Since magnetic field very a little less than, so the remnant field on steel rope surface also very a little less than, and low-intensity magnetic field is stable fine, is not easy decay, magnetic a little less than therefore once loading can guarantee need not reload in three months.
The test section:
The main portion of native system; Utilize the new theory of " space magnetic field vector resultant principle ", add a counter magnetic field earlier, and demarcate; 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 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 rope than the sensitivity of traditional Hall element.
Computing machine: every volume steel rope detects and finishes; Get up detected all data-storings, and can watch this steel rope all instant curve and data when detecting in real time, if any great damage meeting instant alarming; The more serious standard of scrapping of arriving, 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, and with measured object surface maximum clearance: 30mm.
The detection index of this checking system is following:
The uncertainty of quantitatively judging:＜0.05%,
A recall rate:＞98%,
Detect recurrence rate:＞98%,
Quantitative accuracy rate:＞95%,
The impaired loci axial error:＜± 10mm.
Promptly detect up-to-standard steel rope through above-mentioned operation and get into the part that oils,, avoid corroding in order to the protection steel rope with surfaces coated one deck anti-corrosion oil outside.The part that oils adopts immersion, also is that steel rope is immersed in the oil, and in oil, passes by, and oil just gos deep into playing the purpose that oils in the slit of steel rope automatically like this.
During the preparation of this equipment, through investigation, adopt extraordinary anti-corrosion oil, the anti-corrosion oil of above-mentioned use should have following characteristics: viscosity is low, and good fluidity is easy to attached to the steel 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 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 anti-corrosion oil to also have attenuative effect, so its rust-proof effect is more far better than general anti-corrosion oil, and is convenient to operation.
Rolling principle, method and the device thereof of rolling structure in the present embodiment, are similar to and unreel structure.But its reverse movement, that is, along with the progressively increase of winding radius, cireular frequency 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, and this equipment is below fat liquored export orientation assembly; The high-sensitive pressure sensor that is used for weighing apparatus has been installed, because the variation of winding radius causes the variation of linear velocity, thereby causes the variation of tension force; The variation that this is very small, pressure sensor can both detect, and exports corresponding electric signal; Remove to control variable-frequency motor 12, the adjustment rotating speed reaches the purpose that keeps permanent tension force.
Have again, neat basically on the rolling frame for making wire rope roll, before the rolling frame, also adorned bus cable device, be glass pulley, glass pulley 24 is provided with the two-way groove 25 of walking.As shown in Figure 4, when steel rope was being pressed guide wheel movement, guide wheel can rotate on axle, and the guiding trench culture axial motion on axle.When this track adjusting wheel arrives end points, can be along the spirally-guided trench culture counter motion of other direction.Because the bidirectional-movement of this track adjusting wheel 26 on axle, make steel rope be wound up on the pedestal 27 relatively more neat.
Because each steel rope pedestal, add the weight of steel rope, reach more than 1 ton nearly 2 tons.Therefore when pedestal loads and unloads, go up and down with the helical screw jacking device.Unreel and the rolling structure, the elevator that each has adorned 10 tons of lifting powers can go up and down respectively.
In the present embodiment, control part adopts a PC programming controller (not shown), and as the cardiac component of equipment package, 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 rope, as long as press start button, fully automatic operation then.In case have fault or steel rope to damage too much, all can report to the police even automatic train stop.
The engineering steel silk rope maintaining equipment of the utility model; 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 said 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 cleaning of the anti-winding steel wire for engineering of the utility model, detect, oil integrated device and method thereof also reduce the maintaining cost and the supervision of construction cost of steel rope significantly.
The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model design; Can also make some improvement and retouching, these improvement and retouching also should be regarded as in the protection domain of the utility model.
