Research On The Backup Protective System Of Mine Hoist

The mine hoist is one of the important mineral mountain equipments, it is veryimportant to contact the ground and the bottom of a well in the whole mineralwell.The characteristic of mine hoist is that multi-tache, the complicatedcontrol ,circulate speed quickly,inertial quality big,complicated the characteristicsof circulation the condition of work usually converts alternately.Although the minehoist have some a protection measure of safety and promotes the credibility of themachine for the sake of the exaltation,people carriedon an improvement from themachine,electronics,maintenance,management...etc., obtaining certain result.Butbecause the bad environment condition(dust,pour a heavy thing of the water andwhereabouts to hurtle to hit etc.) of the spot usage resulted in the function ofvarious machine spare parts and the electricity component lose efficacy, and theartificial mistake of the operation and study to the route of travel monitor of limitsex, make existing the protection can not attain an expectation of result, cause thetrouble of promote the system not yet can remove up to now.Once promoting theroute of travel of the machine out of control, have no according to give to settle thespeed curve movement, will take place to promote machine to exceed the speedlimit,lead book trouble, light result in the wedgelike form bottle way,bottle the cageinjure, influencing the mineral well to produce normally.Serious of can pull to thewell and make the steel wire rope break,promote container to sink into and breakand make unusable to combine the machine electricity equipments in the tube,result in thus the important personnel dead and injured trouble and importantequipments trouble, bring the coal mine production tremendous economy loss.Currently, our country of a lot of coal mines, the mineral well promotes theprocess signal to still adopt the machine type method, credibility bad, maintenancehave great capacity, because signal confusion and result in of promote trouble alsohour have occurrence, all these is not mached with the safe form of the coal mineand the development of the mineral well.Be showed from this, resolve to promotethe machine route of travel, the speed surveillance problem is the key that prevent°froms promoting the machine severity trouble.But currently, the local mineralmountain mostly adopts the machine type to equip a manifestation, monitoring toIVpromote machine to promote the position and speed, but this kind of equipmentsaccuracy is not high, and protective measure and can act to serious depende theaction of the winch driver.Therefore, the mineral well that develops high accuracy'spromoting spare protection device of machine is the topic of the of the utmosturgency.The research target of this thesis is to promote spare protection system ofmachine in the mineral mountain the production physically applied, to existingspare protect system to carry on the reformation design, the exaltation accuracy,promise the mineral mountain to produce smoothly progress in the more safescope..Design medium full in consideration of protect bad usage environment ofsystem, adopt a strong single slice of function machine system, apply various spotanti-interference measure.Include the adoption enters a line power supply filter;absorption of voltage sensitivity;machine etc..Adopt to promote speed to wrap thecover line control method in the software particularly, make to exceed the speedlimit to report to the police more science is reasonable.Have because of beingsubjected to the saving machine capacity restriction, save a record limited, sodesigned medium increment with the calculator of different step the string go thecommunication function, make saving the record almost limitted, and can carry outa saving data backup,backup and search,gather,statistics,print.But the same kindsystem have not these functions currently.In addition, the steel wire rope of minehoist is the mineral well to promote to accept a heavy parts in the equipments,sometimes needing to be accept heavy reach to 40 and 50 tension of the tons.Themovement circumstance and the loading ability of the steel wire rope relate to tothe equipments and the Human body safety every moment, so the rightmaintenance of the steel wire rope is count for much.Promotes what machine bearto carry the lotus dissimilarity and promote the route of travel of the machine in themineral mountain production line, the way dissimilarity for promote, the steel wirerope that leads to promote machine pulls to stretch produce of transform to alsohave very different, if promote the machine steel wire rope to be subjected to thedint asymmetry and may cause a cordage split, other few steel wire ropes will alsosplit one after another.If carry on an examination to the tension of the steel wirerope, and can record down, can discover among them of the tension variety processof each cordage, can adjust the steel wire rope to make them attain to be subjectedto dint even, thus can't because the difference of of the tension of the steel wirerope leads greatly or the tension exceed extreme limit but split.Therefore, this texthope after being subjected to the steel wire rope the dint,contingency and strengthcarries on the theories analysis, the ability increases to the tension that promotesthe machine steel wire rope on the function of this protection system whether carryon protective function normally.The whole system that backup protection system of mine hoist adjusts to tryprocess to divide three stages to carry on, first according to the function of theprotection system with match an industrial department of coal the coal mineappropriation equipments to standardize the technique committee to put forward ofpromote the machine protection system standard, make sure promoting the machineprotection system system hardware constitutes to constitute and software oftechnique index sign;make use of the calculator emulation to imitate true systemsecondly to request to carry on the software development test and the cent segmentof the hardware to adjust to try according to the system design, complete the wholesystem emulation to imitate a true test on this foundation structural with theverification system hardware of whether the rationality and the software functionattain the design request or not, the laboratory that completes to protect systemadjusts to try;Be protecting system into the mineral mountain production to carryon install physically finally and carry on the on-line adjust to try to promotemachine originally by verification spare protection whether the system wholefunction and function can attain design index sign or notPass by to design of carried on the backup protectivesystem and limit toprotect calculate way to carry on the spot soon behind of on trial, can see aprotective system can attain the design request, adopt of the calculate way isreasonable, controling the request that the result can satisfy the mineral mountainproduction line.
