Description
Technical field
The present invention relates to a kind of encoder, particularly to a kind of elevator rope code-disc conflict device.
Background technology
Encoder is a kind of angular displacement or straight-line displacement is converted to the signal form that may be used to communication, transmit and store
Equipment, and the digital encoder habituation measuring angular displacement is referred to as code-disc, has that resolution capability is strong, certainty of measurement is high and work
Make the advantages such as reliable, be a kind of the most frequently used displacement transducer of measurement axis angle position.At present in the equipment control of a lot of industries
System, product manufacturing aspect are widely used.
Geometry of machinery displacement on output shaft is converted into pulse or number by opto-electronic conversion by digital sensor-photoelectric encoder
Word amount, this is to apply most sensors at present, is made up of grating disc and photoelectric detection system.Grating disc is at certain diameter
Several slots are partially opened on plectane.Owing to photoelectric code disk is coaxial with rotary body, rotary body rotate time, grating disc with
Its synchronized rotation, through the detection device detection some pulse signals of output of the electronic component compositions such as light emitting diode, its principle is shown
It is intended to as it is shown in figure 1, decoder internal has code-disc grating, is rotated by rotating shaft.Light is beaten at receptor (light by grating
Quick pipe) above form pulse signal and export.
The major and minor well of iron mine promotes system in the accurate detection realizing the operation depth location of the skip bucket (cage) to elevator
On, all use dial sensor technology, system use two photoelectric encoders (code-disc) altogether, wherein one be only installed at main shaft to
On the shaft of watch-dog, another is driven by steel wire rope by clutch.By the comparison of rope code-disc with axle code-disc measurement data,
Guarantee winching barrel swing offset and steel wire rope straight-line displacement basically identical (deviation is not more than 3M), thus provide exact depth and refer to
Indicating value, it is achieved the protection of automatically controlled aspect.When in elevator running, two code-disc position deviations are more than 3 meters, then safety is returned
Road disconnects immediately, system monitor prompting " the overproof fault of code-disc ".
Rope code-disc utilizes the clutch (rubber quality is commonly called as rubber wheel) of coaxial rotating to conflict with cylinder steel wire rope, keeps
Suitably frictional force, moves drive rubber wheel rotation by steel wire rope and makes code-disc carry out depth calculation.Computational accuracy often with steel wire
Restrict relevant to the swing situation of coefficient of friction, conflict mode, the degree of wear of clutch and drive mechanism between clutch.
And these influence factors all to directly depend on rope the most advanced perfect, the application performance of code-disc conflict device the most stable
Reliably.It is investigated that card, code-disc conflict device of restricting at present do not unify standard in association area, manufacturing market does not has matured product to carry
Confession, is each use unit and researches and develops making voluntarily, actually used in there is also various problems and shortcomings, be mainly manifested in:
Rubber wheel and steel wire rope hard contact, conflict power can not keep automatically.After life-time service, rubber wheel race is due to mill
Damaging, reduce with steel wire rope contact surface, frictional decrease, the rotation causing rubber to take turns can not be synchronize with wire rope displacement, occurs
Skidding, the deviation that fathoms direct initiating system alternate position spike fault, it is necessary to regular adjustment base support integral forward lead, protect
Card rubber wheel is conflicted good with steel wire rope.Original device hard contact, it is impossible to elastic self-propelled, artificially overhauls heavy load.Former
Device rubber wheel can not lean forward, and setting angle is limited, causes subsidiary abrasion.Original device lacks rubber wheel forward tipping mechanism, and if steel
Cord front vertical is conflicted and must be promoted comprehensively with rope code-disc actuating device by rubber wheel, because mechanism size reason exists and steel wire
There is the hidden danger of scraping in rope, reel, lateral deviation 120 ° can only be used to fix.Thereby result in following two problems:
1, taking turns lateral deviation conflict steel wire rope because of rubber, race monolateral stress friction, the degree of wear is deeper.Rubber wheel one side due to
Uneven stress, causes another side abrasion more serious so that rubber wheel coil diameter shortens, and is easily generated calculating error, the most every 15 days
Just need to adjust a rubber wheel and steel wire rope of hoist contact position.And along with abrasion aggravation, within every 3 months, integral replacing must be needed
One new rubber wheel, accelerates the used life cycle of rubber wheel；
2, lateral deviation causes friction lining surface wear on elevator drum serious to conflicting equally, its reason mainly due to
When rubber wheel is installed, deflection 120 direction is installed, and causes rubber to take turns just against the askew friction lining to homonymy of steel wire rope.Long this with
Toward causing the installed surface friction lining abrasion in rubber wheel deflection 120 direction, reach to a certain degree friction lining on elevator drum
I.e. scrapping, it is necessary to stopping production integral replacing, the equipment that has a strong impact on runs well, and causes subsidiary friction lining impaired, adds maintenance
Cost and maintenance engineering amount.
After lifting system occurs that the overproof fault alarm of code-disc or Daily Round Check find that rope code-disc loosens, be required for and
The adjustment of Shi Jinhang rope code-disc conflict mechanism, fastening.The adjustment difficulty of original device is relatively big, needs first to loosen four fixing spiral shells of base
Bar, integral forward lead carries out coarse adjustment；Pulling 2 support augering screws again to be finely adjusted, 2 augering screw palpus progresses are consistent, can not
Tension or loosen, otherwise can cause rubber wheel unbalance stress, frictional resistance excessive or skid, affect synchronous rotary, adjustment
Precision is difficult to hold.Because iron casting easily becomes rusty extremely, it is often necessary to spraying rust cleaning loosening agent can operate, multi-person synergy 30--40
Minute just can fulfil assignment.The deficiency of global design directly affects that relevant maintenance craft is loaded down with trivial details, upkeep operation difficulty big and
Overhaul efficiency low.
