Description
Technical field
The present invention relates to the improvement of the compensating gear of a kind of steel wire rope for elevator group, particularly one can be to four groups of steel
The stress of cord is adjusted, and makes the stress often organizing steel wire rope reach the symmetry of identical steel wire rope for elevator group
Four node compensating gears of distribution.
Background technology
Current elevator both domestic and external generally uses traction machine to drive elevator, and towed elevator hangs lifting system by traction
The critical piece such as wheel, steel wire rope group, car, balance weight system forms；Described towed elevator hangs lifting system
In be wound around in the groove of traction sheave by every steel wire rope in steel wire rope group and the frictional force that produces provides car
The power promoted or decline；Under the regulation of elevator actuation techniques development, the hoisting depth of elevator and row
Sailing speed to be all greatly improved, the most also the safety and reliability to elevator self proposes higher wanting
Ask.In theory, elevator in use, should equally, and drag by the stress of every steel wire rope in steel wire rope group
The shape and size of the groove being used for lay winding wire ropes on running wheel also should be equally；But during actually used, due to respectively
Kind of reason can make the stress of every steel wire rope in steel wire rope group different, so will result in some steel wire rope and is subject to
Power is big, and some steel wire rope stress is little；Friction between the groove on traction sheave that steel wire rope that stress is big is corresponding
Power can be relatively large, and the friction that so can cause groove on the traction sheave of its correspondence is more severe, and the time one is long, just
The shape and size causing well the groove on the traction sheave of its correspondence change, and cause the steel wire rope work that stress is big
Power suffered by is increasing.If radius reduces 0.1 millimeter after the groove abrasion on traction sheave, traction sheave often revolves
Turning around, steel wire rope to move 0.314 millimeter less；As a example by the building of 20 layers, traction sheave will be about rotating
100 circles, then will should move less 31.4 millimeters with steel wire rope, through overtesting, find to want many with steel wire rope
Stress about 3000 Ns；When the unbalance stress of steel wire rope in steel wire rope group, steel wire rope that stress is little and traction
Producing crawl between wheel, the wriggling between steel wire rope and traction sheave can cause the mill of steel wire rope and traction sheave
Damage；Floor is the highest, and above-mentioned situation is more serious.Thus, the steel wire rope that the long-time stress used is big was using
Cheng Zhong, is easily broken off, and causes elevator safety accident；Meanwhile, the steel wire rope that stress is little also can because of with traction sheave
Abrasion, occur impaired, if impaired seriously, also can cause the fracture causing steel wire rope, and cause elevator to pacify
Full accident；A kind of the stress of four groups of steel wire ropes can be adjusted to this end, we have developed, and make often to organize steel wire
The stress of rope reaches the four symmetrical node compensating gears of identical steel wire rope for elevator group.
