Description
Technical field
The invention belongs to elevator detection technique fields, are related to balance coefficient of elevator and compensation performance measurement method and test
Instrument.
Background technique
The carriage of elevator and two moving components of counterweight form closed loop by hoist ropes and compensation rope, and are supported on traction
The traction sheave two sides of machine, and be limited on respective vertical guide rail by directive wheel and compensation rope tensioning wheel.When traction machine rotates
When driving traction sheave rotation, between traction sheave and hoist ropes traction (i.e. frictional force) traction carriage and to recast it is opposite on
Lower direction movement is to realize the purpose for transporting passenger, when elevator is run up and down, hanging steel rope length and sedan-chair in carriage and counterweight
It suspends trailing cable length under compartment in midair constantly to change, the coefficient of balance between carriage and counterweight is not stopping to change, especially high
The coefficient of balance variation range of layer elevator is bigger, it is possible to exceed defined 0.4~0.5 coefficient of balance control range, so right
Compensation rope must be installed additional in high rise elevator to compensate influence of the weight change to coefficient of balance of hoist ropes and trailing cable.
In addition, elevator may close people because of power failure or failure hang-up, it is therefore necessary to emergency rescue device be arranged, have
Many elevators are to rotate traction machine with hand-barring, carriage is moved to nearest floor opens elevator door and carry out putting people and rescue
It helps.
Application No. is 200810014550.3 to disclose a kind of torsion-testing method of balance coefficient of elevator, it is characterised in that packet
It includes following steps: 1, when carriage is in identical height with counterweight, different loads is loaded in lift car, measure manual disk respectively
Torque at vehicle；2, according to torque equilibrium equation group, the difference W-G of counterweight weight and car weight is found out；3, using to heavy
Amount and the difference W-G of the car weight and nominal load capacity Q of elevator, calculate balance coefficient of elevator K=(W-G)/Q, and export.
For the tester for realizing above method use are as follows: including torque sensor, force is taken turns and computer, wherein the one of torque sensor
The traction sheave of end and former handwheel or elevator or other there is one of the wheel of drive connection to be fixedly connected with traction sheave, separately
One end is fixedly connected with force wheel, and the output end of torque sensor connects computer.
But its instrument need to be tested by original handwheel, and operation instrument is another operation handwheel, operation again
Its operating force according to torque cannot control to adjust after the solidification of handwheel diameter, need when torque is larger larger
Operating force may cause operating difficulties；Its method is to test carriage with to coefficient of balance when focusing on identical height and position, is surveyed
Test result is a definite value, is not balance coefficient of elevator value range, and the real balance coefficient of elevator is dynamic change, is put down
The coefficient that weighs is value range, and the value range for measuring coefficient of balance with a median of coefficient of balance is ill-considered, because in
Between value can not determination range value peak value it is whether exceeded, therefore its test result does not meet technical standard to balance coefficient of elevator
The definition of (0.4~0.5 should be met)；Do not have the function of the compensation performance test to elevator compensating system；Elevator cannot be tested
Machinery driving efficiency；And it needs to take multiple measurements when applying different loads, large labor intensity, time-consuming, expense
Height is to cause test result inaccurate secondly, more mainly increasing measurement error, first, the measurement error of load will affect survey
Test result, second, the magnitude of Instrument sensor can reduce (magnitude is maximum when unloaded) with load, the smaller measurement error of magnitude is got over
Greatly.
