Description
Technical field
It the utility model is related to a kind of elevator governor responsiveness tester.
Background technology
The limiter of speed of elevator is one very important safety guard of elevator.When the lift car speed of service exceeds the speed limit
When, the electric safety switch on limiter of speed will act, and cut off elevator power supply source, make elevator out of service；When cut-out power supply electricity
When source is insufficient to allow the elevator to stop, the mechanical action device of limiter of speed will act, and speed limiter wire rope be clamped, so as to drive
The safety tongs action of lift car (or counterweight), makes lift car (or counterweight) locked on guide rail, so as to prevent lift car
(or counterweight) further security incident occurs for hypervelocity.GB7588 at present《Elevator manufactures and installation safety standard》To various limiter of speeds
Responsiveness scope be all made that detailed regulation.
Therefore, in order to ensure the safe operation of elevator, the responsiveness of limiter of speed must be accurate.In order to ensure limiter of speed
The accuracy of responsiveness, in elevator daily maintenance and periodic inspection, it is necessary to carry out school to the responsiveness of limiter of speed
Test, that is, detect limiter of speed electric safety switch and whether the linear velocity of the limiter of speed pitch circle at mechanical action device action moment meets
Laws and regulations requirement.In order to ensure the accurate of governor tripping speed, the accuracy of limiter of speed check test instrument will be ensured first.
Have more money limiter of speed Verification Testers on the market at present, but one or two following shortcoming be present：
First：The principle of measurement determines that it can not accurately measure the linear velocity of limiter of speed pitch circle.This quasi-instrument is divided to two again
Kind.The first measurement is the cylindrical linear velocity of limiter of speed runner, and for the approximate speed for replacing limiter of speed pitch circle, this is obvious
It is wrong, is unable to undergo what is considered, especially special equipment examines testing agency to use this detecting instrument, the measurement knot drawn
Fruit does not have the effect of legal arbitration.Second is by installing small magnetic beans on limiter of speed pitch circle, then being connect with Hall
The rotating speed of nearly sensor detection magnetic beans.When this method detects the speed of small magnetic beans using Hall sensor, limiter of speed circles
Just detect once, therefore the average speed that simply limiter of speed circles detected, rather than instantaneous velocity.Therefore measure
Limiter of speed pitch circle speed is also inaccurate.
Second：On-site manual is needed to measure limiter of speed section diameter of a circle, it is cumbersome time-consuming.Use this measuring method
Limiter of speed tester generally requires the diameter d and speed limiter wire rope that measure limiter of speed grooving diameter dRope, calculate limiter of speed
Pitch diameter dSection=d+dRope, the diameter of limiter of speed grooving bottom is typically detected during detection, then converses limiter of speed section diameter of a circle.
The structure of limiter of speed and field erected environment are limited to, general is difficult directly to measure limiter of speed grooving with measurers such as slide measures
Diameter d, it is necessary to which the girth that limiter of speed grooving is measured with rope calculate and obtains limiter of speed grooving diameter d indirectly.Due to rope
Son is not the measuring instrument by metering, and governor rope well width is nor the width of a rope, therefore is measured
Result be on the one hand not necessarily the girth of limiter of speed grooving, on the other hand do not have tractability.In addition, this mode can only be used
In the limiter of speed for detecting U-shaped grooving, the limiter of speed of V-type grooving and the U-shaped groove of the notch can not be measured, use range is narrower.
Utility model content
For overcome the deficiencies in the prior art, the utility model provides a kind of elevator governor responsiveness tester,
Limiter of speed grooving diameter and speed limiter wire rope diameter need not be measured when carrying out the test of limiter of speed field-checking, can accurately be surveyed
The linear velocity of limiter of speed pitch circle is obtained, the linear speed of limiter of speed pitch circle is accurately measured in limiter of speed electrical action and mechanical action moment
Degree, and the influence of the abrasion of unrestricted fast device grooving shape, speed limiter wire rope and the abrasion of limiter of speed grooving.
