Detailed description of the invention
A kind of long distance steel cable belt fast exchanging process, step is:
1) new band ground vulcanization gelatinization joint is integral, and use the new adhesive tape that 500m is long, the adhesive tape of about 5000-5500m only needs to use the new adhesive tape of 10-11 bar.
For improving adhesive tape bulk strength, take following measures:
(1) reduce joint quantity: will often roll up virgin rubber unit band in the past be about 250m length, change employing into and often roll up about 500m length (adopting spectacles convoluted mode), to reduce joint quantity, FS final spice quantity reduces to 11 by 21.As the ring that entire volume adhesive tape is the weakest, namely the minimizing of joint quantity means the remarkable lifting of adhesive tape global reliability.
(2) as schematically shown in Figure 1, vulcanized joint operates, and tape splice angle is 16.7 °, for improving strength of joint, primary standard length of bench is risen to 750mm by 650mm.Joint length, by full-length 2450mm, changes 2750mm(into and comprises groove length); Strict control sulfuration process, adopts import vulcanizer to carry out press cure (curing temperature is set to 150 ± 5 DEG C, pressurization 1.24Mpa, constant temperature time 57 minutes), guarantees vulcanized quality, joint static strength >100%.
2) anticipate as shown in Figure 2,3, utilize bolt 6 to link together on new adhesive tape 3 and old adhesive tape 1, wherein the end portion inflection of new adhesive tape, inflection section links together with bolt 6 is overlapping with old adhesive tape 1, and laminating length is 5m, and bolt 6 is totally 6 rows, often arrange 12, be evenly arranged between each row.
Utilize bandage-winder as winch, by new adhesive tape 3 from storage zone through main shaft mouth landlord side steel structure leader tape platform 4, pull in heapstead along main slant sealing-tape machine trend, utilizing drives a vehicle in main shaft the room in slings new adhesive tape, then will take the lead reverse reflex.New adhesive tape 3 is coincided with the upper and lower with old adhesive tape 1 and stacks, draw center line respectively and carry out centering, both sides, superimposed for adhesive tape place are checked card fixing.For ensureing the superimposed precision of new and old belt, new and old adhesive tape gluing length is 5m.8.8 grades of M10 high strength bolts are adopted to carry out punching fastening (totally 6 rows, often arrange 12, and between each row, bolt is evenly arranged).For avoiding bolt to be damaged by cylinder surface encapsulate through head roll, opening bolt slot at new and old tape surface respectively, making bolt cap tail height surface lower than tape surface.Greater impact power is produced through lower bottom carrying roller for avoiding new adhesive tape, and cause carrying roller to fall down or rubber belt from deviating, new adhesive tape forefront local complexity glue and steel rope are polished by certain slope cutting, recycling TIPTOP repairs adhesive tape together with old adhesive tape bonding, thus forms slope section transition.Accompanying drawings is as Fig. 2, Fig. 3.
3) open main shaft sealing-tape machine, utilize old adhesive tape to import new adhesive tape.
Open main slant sealing-tape machine, make old adhesive tape 1 with the belt speed of 0.2m/s at the uniform velocity, cw, traction new adhesive tape 3 and is imported from head head roll 7 lentamente, new adhesive tape 3 is through head secondary head roll 8, secondary bend pulley 16, tightening device 14, aircraft tail cylinder 13, head head roll 7, again after secondary head roll 16, complete new adhesive tape 3 and lay operation.After examining size, clip unnecessary new adhesive tape at head.
4) old adhesive tape is disconnected, the new adhesive tape of sulfuration.
Install 4 place's hydraulic pressure strap clamps in well head tightening device 14 both sides respectively, be respectively: No. 4 strap clamps 9, No. 3 strap clamps 11, No. 2 strap clamps 13, No. 1 strap clamp 15; (relative arrangement is shown in Fig. 4), first utilizes
No. 1 strap clamp 15, No. 2 strap clamps 13, No. 4 strap clamps 9 are by upper and lower two-layer adhesive tape clamping.Unclamp tightening device 14 manually, the old adhesive tape between well head No. 2 strap clamps 13 to No. 4 strap clamps 9 is relaxed, the tension force of release adhesive tape own.In backhaul adhesive tape vulcanizing platform 10 region, cut off with abrasive cut off machine and remove the old adhesive tape of corresponding length, then clamping new and old adhesive tape with No. 3 strap clamps 11, then retighten tightening device 14, vulcanization gelatinization joint is carried out to the two ends of new adhesive tape 3.
Before sulfuration, examine tension position, safe operation needs are from now on met in line with stroke of tension, and storage ribbon amount possesses the principle again making a vulcanized joint from now on and need, take into consideration stretched length that the old adhesive tape corresponding prolongation amount that to hold when cylinder crossed by new adhesive tape, the deadweight of old adhesive tape produce new adhesive tape and new adhesive tape put into operation after work elongation itself, when new adhesive tape vulcanization gelatinization joint, then the storage strip length of 1.5m that the new adhesive tape of sulfuration section has been had more than needed out.
5), after new adhesive tape links into an integrated entity, new adhesive tape is utilized to derive old adhesive tape.
Unclamp No. 3 strap clamps 11, No. 4 strap clamps 9 successively, unclamp tightening device 14 manually and make well head section virgin rubber belt sag.With driving a vehicle in main shaft room new adhesive tape being sling on the left of a head roll 7, reserving construction space, utilizing abrasive cut off machine to be disconnected by old adhesive tape, and hang down.Then manually open tightening device 14 and tighten up the new adhesive tape of well head section, unclamp No. 1 strap clamp 15, No. 2 strap clamps 13 and make the new adhesive tape tensioning of whole piece.As schematically shown in Figure 5, the vertical bend pulley group 18 of two vertical duction carrying roller compositions is installed on the downside of new adhesive tape 3, one the 45 degree changed course pipes arranged, with a side, the derivation change course device 17 of guide pulley composition is installed, make sagging old adhesive tape 1 through vertical bend pulley group 18, derive change course device 17, under loader 19 draws, tensioning is stressed.Open main shaft sealing-tape machine, with the belt speed of 0.2m/s, utilize friction force and the loader tractive force of new band, old adhesive tape is turned to and involves, often involve about 150 ~ 250 meters, stop main shaft sealing-tape machine and loader, disconnect old adhesive tape.Then again open main shaft sealing-tape machine, utilize loader to be involved by next section of old adhesive tape.And so forth, until had been friends in the past adhesive tape is withdrawn from.As schematically shown in Figure 6, utilize at aircraft tail cylinder 12 place simultaneously chain block 20 and can the flat carrier roller of horizontal slip as storage band and take-up device.
Note: when withdrawing from the old adhesive tape of final stage, have the drop of 5 meters nearly, may clap bad by lower methods, rack as directly fallen.For this reason, the on-the-spot drooping section at old adhesive tape, installed twice and tightened carrying roller, per pass carrying roller is by rope.When making this section of adhesive tape fall, discharge larger impulsive force through carrying roller buffering.
6) the old adhesive tape involved is reclaimed by tape handler.
Utilize loader for anchor fitting, tape handler is held, then by variable frequency regulating speed control, the old adhesive tape backrush piecemeal will involved with tape handler, until complete the recovery operation of whole old band.
As can be seen from above-mentioned detailed description of the invention: key problem in technology of the present invention and difficult point how to solve and handle well the new and old adhesive tape problem that tension force is inconsistent brought each other, and realize changing new adhesive tape safely and fast on this basis and withdraw from old adhesive tape.Relevant innovative point is as follows:
(1) new and old adhesive tape has mutually depended on and has removed old band into new band.
Utilize existing actuating device, elder generation with new adhesive tape by old adhesive tape, is completed new adhesive tape and lays.After new adhesive tape vulcanization gelatinization joint, then rely on friction force old adhesive tape in tow by the new adhesive tape in outer ring, derived.Because new and old conveyor belt tension is difficult to unanimously, the low adhesive tape of inner ring tension force must be caused calendering occurs to extend and wrinkle, crowded entering cylinder place, and then affect tape swapping work.And, going out in old adhesive tape process, cannot provide because old adhesive tape is positioned at position, head roll slack list the tensile force continuing equilibrium, and easily skid, thus it is being inboard to cause old adhesive tape to be laminated on new adhesive tape, cannot realize normal derivation.Therefore, old adhesive tape should be disconnected before head roll, make old adhesive tape no longer walk around head roll, and directly withdraw from smoothly under new adhesive tape friction force and the synergy of outside loader tractive force.Meanwhile, for ensureing, between the new and old adhesive tape of carrying section, obvious slippage does not occur, in well head 13 ° of gradients, upper supporting roller is replaced by Non-return idler.In addition, note also, lay in process at new adhesive tape, due to the effect of new adhesive tape partical gravity, tensioning winch is stressed will progressively be increased, for avoiding tensioning dolly to cause old conveyor belt tension to decline and the situation of the old adhesive tape excessive sag of generator rear by its effect downslide, tensioning winch must be strained on the original basis further, and keep winch position that large movement does not occur.
(2) old adhesive tape right angle folding involves.
Tradition turnover band is straight line or oblique line directions carries out operation, is subject to site space restriction.And this time remove band, by installing 45 degree of steering hardwares, completing old band smoothly and withdrawing from work.And, as long as steering hardware arranges rationally, theoretically, can complete and enter to remove band work at any angle.
(3) auxiliary storage belting is set.
Because lower floor is that old adhesive tape carried by new adhesive tape, both contact closely, and friction force is large each other, and upper strata is virgin rubber band press against old adhesive tape, by new and old belt pendency degree Different Effects between carrying roller, both area of contact are relatively little, and friction force is less than lower floor's adhesive tape each other.Thus, the old tape speed in upper strata is slightly less than the old tape speed of lower floor, and the new adhesive tape in upper strata has slight slippage between new and old adhesive tape in the old adhesive tape process of dragging, and consequently old adhesive tape occurs to fold and piles up and band work is removed in impact after walking around aircraft tail cylinder.For this reason, utilize at tail place chain block and can horizontal slip flat carrier roller as storage band and take-up device solve this problem well.
