Description
Technical field
The present invention relates to elevator drive technology, especially a kind of lossless elastic elevator rope end combination.
Background technology
Fag end combination be hoist ropes with car, counterweight or with the bogeys connecting component such as computer room spandrel girder.At present
There are three types of fag end combining forms：Eccentric steel wire rope head combination, the combination of concentric steel wire rope head, the combination of steel band fag end.First two is transported
It is in the main body being driven with steel wire rope is matched with；The third is in the main body being driven with steel band is matched with.No matter its mating master
How body becomes, and how the payload ratings of elevator, normal speed become, and structure will not all change, and is only to change its component ruler
Very little size matches.
Fag end combination is other than mainly undertaking the effect of connection transmission main body, and also spring is arranged, this, which just imparts it, has
There is vibration-inhibition.However there is also a problems at present：I.e. when installation is complete for elevator, after normal operation, could find
On the same stage the multistrand rope of elevator or steel band (hereinafter referred to as steel wire rope) although tightening degree it is extremely close but and it is non-equal, if again
It is unanimously very difficult that tightening degree, which is adjusted, and reaches, and is actually also impossible.Due to being all in industry
Winding multiply and longer steel wire rope are gone by people, its tightening degree must be caused to differ.What tension differed greatly can only pass through fixation
Car, counterweight etc. tighten steel wire rope to realize tightening degree；Subtle tension is inconsistent can only to compress fag end combination by adjusting
Spring realize, but be only at this time under the elevator stationary state, as long as due to or individual fag end combinations spring-compressed
, the running steel wire rope tension of elevator still can be inconsistent.Therefore, existing product is there is clearly disadvantageous：It adjusts
It is laborious, time-consuming between section steel wire rope when big tension difference value；It, can not be complete and when small between adjusting steel wire rope tension difference value
It is complete to adjust to consistent.Thus the problems such as consequence brought is elevator shake, and noise is promoted.
Invention content
The purpose of the present invention is to solve the above problems, provide a kind of lossless elastic elevator rope end combination.
The above-mentioned technical problem of the present invention is mainly to be addressed by following technical proposals：A kind of lossless elastic elevator
Fag end combines, including the rope hitch plate being fixed on driving pedestal, the guide rod being vertically threaded through in rope hitch plate are located above rope hitch plate
Buffer spring and the wedge assemblies below rope hitch plate, it is characterized in that the buffer spring bottom be equipped with it is double subtract rubber,

In the lossless elastic elevator rope end combination of one kind above-mentioned, preferably, the buffer spring bottom is equipped with Spring Card
There is the raised body with buffer spring minor diameter fit, the bottom surface of spring stand to subtract rubber compounding with double for seat, the top of spring stand.
In the lossless elastic elevator rope end combination of one kind above-mentioned, preferably, the guide rod is full thread rod piece, branch seat tool
There is regular polygon external form.
In the lossless elastic elevator rope end combination of one kind above-mentioned, preferably, it is tight to be equipped with double padlocks at the top of the guide rod
Nut.
In the lossless elastic elevator rope end combination of one kind above-mentioned, preferably, described double rubber that subtract are that endoporus is more than and leads
The tubular structure of 1.1 times of bar outer diameter or more.
In the lossless elastic elevator rope end combination of one kind above-mentioned, match with double rubber that subtract preferably, being equipped in the bearing
The hole seat of conjunction, double outer diameters for subtracting rubber are interference fitted with hole seat endoporus.
In the lossless elastic elevator rope end combination of one kind above-mentioned, preferably, the holder top is equipped with subtracts rubber with double
The hole seat of glue cooperation, double natural heights for subtracting rubber are more than the depth of hole seat.It remains double and subtracts rubber and buffer spring in work
Common elastic buffer effect during work.
In the lossless elastic elevator rope end combination of one kind above-mentioned, preferably, the buffer spring is both ends broad in the middle
Small double-cone spring.
The technical program is mainly designed from following several respects：When in terms of product structure, this dress of comparison existing product
The space installed needed for setting will not increase, and make full use of the basic structure of existing product, and design has newly in the useful space
The component and component combination of effect；Second is that respected existing agent structure, avoids production, assembling line from reseting, reduce production
Product exploitation input；Third, the subversiveness redesign of functional effect combines certainly when elevator proceeds to installation fag end combination in fag end
Under right state, ensureing spring stand away from the buffer spring height one between locking nut to can keep slow in practical application
It rushes spring to be under natural height state, then adjusts steel wire rope tightening degree, then drive tenon to be done on guide rod by bearing
Vertical Free adjust, to control the tension difference value between steel wire rope, only it is this under natural conditions, measured by chest expander
Tension value is identical, and could to illustrate that all steel wire rope actual tensions are only really identical；Due to being by under buffer spring when adjusting
The bearing at end and by way of screw thread rotation come what is adjusted, under the premise of ensureing degree of regulation, actively stretch steel wire rope
Elasticity, and when by chest expander measure tension value it is identical when, unclamp screw thread bolt, bearing and tenon made to be detached from, so far, because of electricity
The compressed by weight buffer spring of ladder.
Therefore, there is following operating characteristic and " lossless " conclusion：Because obtaining the homodyne force value on practical significance, sheet when work
Device all components form " lossless " system；Ensure that multistrand rope really obtains subtracting for buffer spring in the process of running
Shake effect；Multistrand rope buffer spring during equal tension adjusts is kept to be in " lossless " state；It keeps double and subtracts rubber
Nature " lossless " state is in during tension adjustment.
The beneficial effects of the invention are as follows：Not only the tension value of strong guarantee multistrand rope is under identical hard conditions
It measures, and buffer spring is transformed into damping adjusting from existing by compression adjustment, to realize elevator stable operation, brings superelevation
Comfort；And when the spring life of fag end combination terminates or when the spring force that project is matched mismatches, replaces spring
Without lifting by crane the associated components such as car, to save operating cost.
