Description
Technical field
The invention belongs to elevator accessory technical fields, and in particular to a kind of lift car traction rope rope socketing device is used
In fixed lift car traction rope fag end.
Background technology
Above mentioned lift car traction rope is under the work of traction machine by the traction sheave of traction machine band to frictionally
It is dynamic, and the both ends of traction rope respectively pass through rope socketing device and hoistway（The channel run up and down for lift car）The load at top
Body is fixed（The carrier at top is commonly referred to as " hoistway supporting plate " or " rope hitch plate ", the same below）, and drawn in the middle part of traction rope and i.e. around set
In elevator traction machine traction sheave, car wheel in elevator car roof is set, and draw and i.e. around the counterweight for being placed on clump weight
Block guide wheel.
Technical information about lift car traction rope rope socketing device can be seen in disclosed Chinese patent literature,
Such as Authorization Notice No. CN201268536Y（Belt type towline head combination）、CN202464993U（Rope socketing device）With
CN203593492U（A kind of elevator rope end compressed spring stabilising arrangement）, etc..In addition, also shown in analogous technical fields it is all,
Such as Authorization Notice No. CN203743308U recommendations have " rope socketing device in lifting equipment ".
The logical disadvantage present in the rope socketing device that patent formula exemplified above provides is not limited to by patent of invention Shen
Please publication No. CN104370181A " rope socketing device " recommended make up, for details, reference can be made to the specifications of the CN104370181A
0004th section, 0018 section and 0022 to 0028 section.But the CN104370181A still has following shortcoming：First, due to needing
The fag end of traction rope and fag end loop bar roll compacting are fixed, for example, in specification the 0028th section point out：" fag end of traction rope is inserted into
It the lower end of fag end loop bar and is squeezed by Press Plier, so that the lower end of fag end loop bar is deformed and is reliably squeezed with fag end and close one
It rises, the conducting wire hydraulic Press Plier in Press Plier such as power line construction instrument or similar device, thus the fixed operation of fag end
It is cumbersome and lead to that installation effectiveness is low and installation difficulty is big due to need to be by the Press Plier as peripheral equipment；Its
Two, since the affixed region of fag end and fag end loop bar is limited only to the region for squeezing slot, in addition traction rope and fag end loop bar
Material it is different, coefficient of thermal expansion and contraction is different, thus loosens there are fag end or even from the anxiety that fag end loop bar is shaken off, current solution
Method is replaced in time in periodically or non-periodically inspection.
" the lift car traction rope rope socketing device " that CN204778175U recommends compensates for above-mentioned insufficient and objective
On can fulfil the strong points of three aspects concluded in the technical effect column of its specification.But the CN204778175U is in addition to fag end
Loop bar, conic clamp rope sling（Patent claims " taper cutting ferrule "）And outside locking screw mother set, the upper end also with one and fag end loop bar connects
Damping supporting mechanism that is connecing and being supported in a state of use on the aforementioned hoistway top plate of aforementioned well headroom, the vibration damping branch
It includes a screw rod and the lock nut that is arranged as carrier using screw rod to hold mechanism, bearing dish bowl, spring, spring lower support on spring
Dish bowl and screw rod headgear, thus there are following technical problems：First, since the structure of damping supporting mechanism loses reasonability, because
And keep entire lift car traction rope rope socketing device occupied space big, fiber crops then can be brought to the limited occasion of installation space
It is tired；Second, since the component number of damping supporting mechanism itself is more thus complicated, both it is not easy to make and assembles,
It is unfavorable for embodying economy and also causes the wasting of resources；Third, the screw rod of the structural system due to aforementioned damping supporting mechanism
Only realize with a locking pin and connect with fag end loop bar, thus the stress of locking pin is big, once occur being broken or similar situation if
Accident can be caused.
In view of the above-mentioned problems, the applicant has made beneficial design, and form technical solution described below.
