Description
Technical field
The present invention relates to a kind of method of testing and detecting instrument, more particularly, the present invention relates to a kind of method of testing and instrument of testing elevator governor.
Background technology
Limiter of speed-safety tongs linked system is called as last one security perimeter of elevator safety operation, is also a most important proof protecting device, and the accuracy of responsiveness is directly connected to the security of elevator operation.If governor tripping speed is too low, easily cause equipment malfunction to do, affect the normal operation of elevator, and easily cause equipment damage; As too high in governor tripping speed, anti-overspeed protection was lost efficacy, and directly caused serious falling accident, caused serious personnel and property loss.So, extremely important to the safe operation of elevator with verification to testing of governor tripping speed.
When inspection body carries out verification to limiter of speed at present, conventionally adopt following two kinds of equipment:
(1) elevator governor tester, volume, weight are all larger, when use, fritter magnet are attached to the side of governor sheave, adopt Hall element collection signal, calculate the linear velocity of limiter of speed pitch circle by surveying the Lap Time of governor sheave.Gather pulsatile once signal because governor sheave often turns around, and the speed of governor sheave changes, so the numerical value of measuring and limiter of speed action actual speed exist certain error.The size of drive motor is large, carry inconvenience; The power limited of drive motor, is not suitable for the use of high-speed governor; Drive motor lives forever in overheated phenomenon service time; In the time detecting operation more loaded down with trivial details, length consuming time; There is no data storage and backup.
(2) equipment that special velocity metre combines with speed-regulation electric drill: drive rope sheave with speed-regulation electric drill; Special velocity metre is contacted to detect the speed of rope sheave edge with governor sheave, the phenomenon of skidding due to existence, so also there is larger error in the speed detecting.By the unexpected stop of governor sheave, the action numerical value of measurement may be the numerical value having reduced, so tend to produce mistake, need to again detect.
Existing equipment exists driving force deficiency, is not suitable for high-speed governor, error is large, volume carries greatly inconvenience, complex operation, countless according to problems such as storages.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of and be easy to carry, easy and simple to handle, test result, be beneficial to the elevator governor tester of information system management.This instrument is with reference to the achievement in research of existing measuring instrument on market, take existing elevator inspection rule as reference, emphasis solve existing instrument and equipment heaviness, test result can not information system management etc. problem, and further improve precision and the Site Detection efficiency of test result.
The present invention is achieved by following method of testing: when test, first on the wheel disc of tested limiter of speed, paste a reflective masking foil, optoelectronic switch is arranged on and is used on the fixing special stand of universal magnetic gauge stand, and regulate photoelectric probe position, the reflected signal of masking foil can be detected, use the even acceleration of the motor showing with rotating speed to drive the wheel disc of limiter of speed, optoelectronic switch collects the turn signal of wheel disc, send data acquisition module to, the velocity of rotation of what data acquisition module was real-time calculate limiter of speed wheel disc, and can input the electrical action and the mechanical action that perceive limiter of speed with sound transducer by switching value, and be reported to man-machine interface, man-machine interface demonstrates the velocity of rotation curve of limiter of speed wheel disc, etc. test result, and can real-time storage.
In order to realize the present invention, design a elevator governor tester by drive motor, optoelectronic switch, data acquisition module, man-machine interface, Portable printer, analysis management software etc. form as shown in Figure 1.
Described drive motor with rotating speed display device, and has been installed driving wheel in rotating shaft; It act as and drives limiter of speed wheel disc, makes wheel disc do even acceleration and rotates.
Described optoelectronic switch, mounting means as shown in Figure 2, is arranged on optoelectronic switch with on the fixing unit clamp of magnetic stand, and its effect is to detect the masking foil being pasted on limiter of speed wheel disc through out-of-date heliogram.
Described data acquisition module, for detection of the actuating signal of electric switch that receives optoelectronic switch and limiter of speed, and can pass through the mechanical action signal of perception of sound limiter of speed, through data reduction result the mode by Bluetooth wireless transmission real-time pass to man-machine interface.
Described Portable printer, passes through the mode interaction data of blue tooth wireless communication with man-machine interface, for printing test result.
Described man-machine interface, for real-time reception and show rate signal and the limiter of speed actuating signal that data collecting module collected arrives, and can preserve, print, retrieve, upload test result.
Described analysis management software, for data management and the analysis of magnanimity, remote access, rights management.
The present invention's major advantage is compared with prior art: intermediate data and test result light, accurate, that also energy real-time storage is measured.
