Description

A kind of elevator without machine room
Technical field
The present invention relates to elevator without machine room, the elevator without machine room that particularly a kind of baudrier is 1:1.
Background technology
For the consideration of traction and hoistway space, current installed machine-roomless lift adopts the baudrier of 2:1 mostly.This baudrier, mostly need to be through a traction sheave, and three diversion sheaves greatly reduce life-span of steel rope.Meanwhile, the increase of diversion sheave quantity has not only aggravated the risk that different sound occurs, and the friction between itself and steel rope has also increased the energy consumption of elevator device to a certain extent.
From this some, the baudrier of employing 1:1 is compared 2:1 baudrier and is had obvious advantage.1:1 baudrier can reduce the quantity of pulley conventionally, improves the life-span of steel rope and reduces noise.
Notification number is patent < < machine-roomless lift > > of CN2626110Y, a kind of wiring is disclosed than being the machine-roomless lift of 1:1, this elevator is arranged on well headroom by towing machine and track adjusting wheel, by after-combustion mode, traction rope is wound in traction sheave and track adjusting wheel, two ends connect car and counterweight, one in two pulleys of this device in the projecting plane of car, therefore cause the remarkable increase of well headroom bulk, improved greatly the building cost of building.
Notification number is in the patent < < lift appliance > > of CN100341763C, discloses a kind of wiring than being the elevator without machine room of 1:1.This elevator is arranged on hoistway bottom by towing machine, and a plurality of diversion sheaves are contained in well headroom car projecting plane with external position, and traction rope is baudrier connection car and the counterweight with 1:1 by these pulleys, thereby completes transporting of elevator.Although this device has been realized the wiring ratio of 1:1, has also saved greatly well headroom and bottom space, in order to obtain enough tractions, is provided with a plurality of diversion sheaves, has significantly affected the life-span of traction rope, and there is higher different sound occurrence risk.
Notification number is the patent < < elevator device > > of CN100564222 and patent < < cable that notification number is CN1177100C and adopts in the elevator > > of this cable, discloses respectively flat steel band and the circular rope of surface with non-metal elastomers coat.Compare traditional steel rope, the friction coefficient between this traction rope and traction sheave obviously increases, and can control by the change of material and technique the size of friction coefficient.The increase of friction coefficient, makes just can obtain enough tractions without large cornerite, and this also makes wiring easier than the machine-roomless lift design consideration of 1:1.Yet the lift appliance of traditional 1:1 wiring ratio is inevitable, in well headroom car projecting plane, there is pulley assembly, so just cause the increase of well headroom bulk, significantly improved building cost.
According to grasped data, also do not have a kind of wiring can meet the few and hoistway space of pulley than the elevator without machine room of 1:1 simultaneously and keep these 2 requirements of lower limit, therefore research and develop and a kind ofly can meet this 1:1 wiring of 2 simultaneously and can greatly promote the development of elevator industry than elevator without machine room.
