Description
Technical field
The invention belongs to traction elevator equilibrium factor test technology, be specifically related to a kind of balance coefficient of elevator test macro and method.
Background technology
GB/T10059-2009 " elevator test method " and " elevator surveillance inspection and periodical survey rule-traction and forcibly driving elevator " require the equilibrium factor of elevator to be 0.4 ~ 0.5 or meet the design value manufacturing (transformation) unit, its method of inspection is that " car loads 30%, 40%, 45%, 50%, 60% of nominal payload respectively and does upper and lower whole process operation; when car and counterweight run to same level position; the current value of record electrical motor, draws electric current-load curve with the intersection point determination equilibrium factor of uplink and downlink run curve." the method concrete operation step in inspection is:
(1) lift car and to doing mark when focusing on a horizon on traction machine support and steel rope;
(2) car as prescribed places the counterweight of Different Weight;
(3) elevator runs up and down, arrives traction machine support mark place judge lift car and to when focusing on same level line, read the current data in this moment with clamp on amperemeter test by the mark on range estimation hoist ropes;
(3) in the test form of record of survey, data are recorded and manual drawing equilibrium factor diagram of curves;
(4) according to intersections of complex curve, equilibrium system numerical value is determined.
Wherein, described step (3) adopts during manual drawing equilibrium factor curve and have passed all test points, and from the angle of numerical analysis, this is a kind of interpolation processing, the data point by each test that namely curve is strict.But, in the test process of equilibrium factor, because voltage fluctuation, friction force, windage etc. inevitably have error to produce.And adopt through all test point curve plottings, also just the error of test is kept down, can impact result.Meanwhile, the drafting of different people may cause result inconsistent, brings personal error.For reducing equilibrium factor test error, the method for curve is usually adopted to carry out the matching of equilibrium factor curve, but the false judgment that the method can not avoid data boundary problem to bring.Meanwhile, after inspection on-the-spot test equilibrium factor, also directly do not print the situation of curve and result at present.
In recent years, the research automatically tested of equilibrium factor is in the ascendant.As " elevator balance coefficient measurer " that CN202754650U records, this survey meter comprises position transduser, current sensor, projector, receptor and primary controller, position transduser, projector are arranged on elevator car top, current sensor is arranged on elevator major loop, receptor, primary controller are arranged in machine room, and current sensor connects primary controller.The utility model detects car and automatically to position when focusing on same level, automatic trigger current sensor record current value, and automatically calculate equilibrium factor, thoroughly break away from human element to the impact obtaining equilibrium factor Numerical accuracy, measuring means science, rigorous more, assay is more accurate.But the shortcoming existed is: the sensor being placed in sedan-chair top needs omnidistance study, primary controller function singleness simultaneously.
At present, the method of no-load test equilibrium factor is adopted also to achieve some achievements in research, as the ADIASYSTEM elevator checking system etc. by detecting the detector of traction sheave both sides steel wire rope tension determination equilibrium factor, the method for measuring static state weight difference in two sides of Liaoming Petrochemical Univ's research and development and tester thereof, German TUV company of Anhui Special Equipment Test Inst's research and development.Owing to being no-load test, eliminate the link of repeatedly carrying counterweight, the test duration is short, but its Problems existing is, the dynamic test numerical value that test result and existing elevator inspection rule adopt there are differences, repeatable poor, limits and applies.
