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 supervision and inspection and periodical survey rule-traction and forcibly driving elevator " require the equilibrium factor of elevator to be 0.4~0.5 or to meet the design value of manufacture (transformation) unit, its method of inspection is for " car loads respectively 30%, 40%, 45%, 50%, 60% of nominal payload and does upper and lower omnidistance operation; in the time that car and counterweight run to same level position; record the current value of electrical motor, draw electric current-load curve and determine equilibrium factor with the intersection point of uplink and downlink run curve." the method concrete operation step in inspection is:
(1) lift car and do a mark to focusing on a horizon when on traction machine support and steel rope;
(2) car as prescribed is placed the counterweight of Different Weight;
(3) elevator moves up and down, and the mark by range estimation on hoist ropes arrives traction machine support mark place and judges that lift car, with when focusing on same level line, reads the current data in this moment with clamp on amperemeter test;
(3) record data manual drawing equilibrium factor diagram of curves in the test form of record of survey;
(4), according to intersections of complex curve, determine equilibrium system numerical value.
Wherein, when described step (3) adopts manual drawing equilibrium factor curve, passed through all test points, from the angle of numerical analysis, this is a kind of interpolation processing, the data point of passing through each test that namely curve is strict.But, in the test process of equilibrium factor, because inevitably having error, voltage fluctuation, friction force, windage etc. 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, conventionally adopt the method for curve 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, also after inspection on-the-spot test equilibrium factor, directly do not print at present the situation of curve and result.
