Description
Technical field
The present invention relates to the tension detecting apparatus of a kind of elevator wire rope, particularly one and can be arranged on electricity by high precision test
The tension detecting apparatus of the elevator wire rope of the tension force of the elevator wire rope on ladder.
Background technology
Current elevator both domestic and external generally use traction machine drive elevator, towed elevator hang lifting system by traction sheave,
The critical piece compositions such as steel wire rope group, car, balance weight system；Described towed elevator hangs in lifting system by steel wire rope group
In every steel wire rope be wound around in the groove of traction sheave and power that the frictional force that produces provides car to promote or decline；At elevator
Under the regulation of actuation techniques development, hoisting depth and the travel speed of elevator are all greatly improved, the most right
The safety and reliability of elevator self is had higher requirement.In theory, elevator in use, in steel wire rope group
The stress of every steel wire rope should equally, and the shape and size of groove being used for lay winding wire ropes on traction sheave also should be equally；But it is real
During border uses, owing to a variety of causes can make the stress of every steel wire rope in steel wire rope group different, so will result in
Some steel wire rope stress is big, and some steel wire rope stress is little；Between the groove on traction sheave that steel wire rope that stress is big is corresponding
Frictional force 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, all right causes
The shape and size of the groove on the traction sheave of its correspondence change, and cause suffered power in the steel wire rope work that stress is big more to come
The biggest.If radius reduces 0.1 millimeter after the groove abrasion on traction sheave, traction sheave often revolves and turns around, and steel wire rope to move less
0.314 millimeter；As a example by the building of 20 layers, traction sheave will be about rotating 100 circles, then should will lack motion 31.4 with steel wire rope
Millimeter, through overtesting, finds to want many stress about 3000 Ns with steel wire rope；Unbalance stress when in steel wire rope group steel wire rope
Time, producing crawl between steel wire rope and traction sheave that stress is little, the wriggling between steel wire rope and traction sheave can cause steel wire
Rope and the abrasion of traction sheave；Floor is the highest, and above-mentioned situation is more serious.Thus, the steel wire rope that the long-time stress used is big makes
During with, it is easily broken off, and causes elevator safety accident；Meanwhile, the little steel wire rope of stress also can because of the abrasion with traction sheave,
Occur impaired, if impaired seriously, also can cause the fracture causing steel wire rope, and cause elevator safety accident；In order to avoid sending out
Raw elevator safety accident, elevator needs to do every year security inspection, at present, generally draws the method for steel wire rope to examine with spring scale
The tension force surveying each steel wire rope is the most consistent, and this method accuracy of detection is the highest.
