Elevator safety technical specification《TSGT7001-2009 elevator surveillances are examined and periodic inspection rule-traction is driven with forcing
Dynamic elevator》Add " up retardation test " this project, that is, the band-type brake experiment being commonly called as.Inspection of the project in new inspection rule
Proved recipe method is：" when car zero load goes upward to stroke top with normal running speed, main switch is disconnected, car stop feelings are checked
Condition ".Such method of inspection is excessively simple, how on earth checks stop situation, using how many braking distances to be qualified, is examined newly
Without clearly in rule, this just brings inconvenience to routine check, but braking distance is required certainly.To up urgent
The requirement of Braking test is existing qualitatively, also have quantitative, qualitatively requires it is that car should be by reliable stop and nothing
Substantially deformation and damage, quantitative requirement is that brake hard deceleration is not less than 0.5m/s for normal condition2, for using
Subtract the situation no less than 0.8m/s of stroke buffers2, according to theorem of kinetic energy：S=v2(S represents braking distance to/2a, and v represents electricity
Terraced normal speed, a represents braking deceleration) the car braking distance under different normal speeds, different deceleration can be calculated.
Requirement to descending emergency braking testses result is different to up emergency braking testses, and adding traction machine should shut down
Requirement, in fact this be brake force requirement, in addition the deceleration of car be not to be exceeded safety tongs action or car hit it is slow
The deceleration rushed produced by device.Provided according to GB7588-2003, average retardation rate should be 1.96m/ during progressive safety clamp brake
s2To 9.8m/s2Between, the average retardation rate during car cushion at collision is acted on not should be greater than 9.8m/s2, in other words, under
During row emergency braking testses, the deceleration of such as car is in 1.96m/s2To 9.8m/s2In the range of, then agreement with experimental requirement, but existing
In the experiment of field, judge that result of the test is not easy to operate with the deceleration of car, the braking distance of car need to be converted into, conversion method is same
Sample is according to theorem of kinetic energy:S=v2/2a.It is elevator industry to develop the effective test device for detecting elevator traction performance
Design problem.
The content of the invention

The braking distance and normal speed elevator that speed measuring device, the second speed measuring device, band-type brake signal pickup assembly are tested out meet scope
Braking distance be compared, and whether the braking deceleration traction capacity whether less than normal to judge elevator qualified.Elevator is draged
Draw performance testing device by detecting the rate signal and band-type brake signal of elevator brake process steel wire rope and traction sheave to converse
Braking distance, and braking deceleration.Test device records steel wire rope and traction sheave and is haveing suffered the speed of braking procedure first
Signal and band-type brake time point, digital filtering then is carried out to two-way raw velocity signal by control main frame, speed is drawn out bent
Line V1 and V2, displacement signal is integrated out by rate signal, and draws out displacement curve S1 and S2, equally may be used by rate signal
Acceleration signal is gone out with differential, and draws out corresponding curve, then by band-type brake time point signal can just calculate braking away from
From, braking maximum deceleration, braking average retardation rate, the parameter such as steel wire rope and traction sheave slippage, these parameters finally show
Printed on liquid crystal touch display screen and by printer.It so can effectively detect elevator traction performance.
