Description
The present invention relates to a kind of detection device, more particularly to a kind of detection device of elevator governor for technical field.
Background technology elevator governor is the safety con-trol part of most critical in elevator safety protection system, when elevator exists
No matter which kind of reason causes car to exceed the speed limit in operation, in addition produce fall danger when, every other safeguard protection fill
To put in the case of being not acted upon, then limiter of speed drives safety tongs that linkage action occurs, and makes lift car stop, so, speed limit
The verification of device responsiveness has turned into part important during elevator is examined.
At present, the detection method of elevator governor is that elevator is placed in into inspecting state, and overhauling elevator is opened to car and departed from
Layer door region, using locking pliers in speed limiter wire rope up direction porch clamping steel wire rope, elevator crawl is up, to moving up
Move to elevator during 150~200mm and stop, steel wire rope is lifted using instruments such as nipper pliers, determine that the space can set up limiter of speed
The driving wheel of tester motor, upward crawl operation certain distance, cut-out elevator power supply, measurement limit elevator again if space is inadequate
Fast device wheel circumference circle, connects power supply, driving wheel, sensor of limiter of speed tester etc., and small magnet is placed on into speed limit device wheel
The suitable position of disk, limiter of speed electric switch are connected on sensor, are determined that what limiter of speed tester can sense arrives, are opened limiter of speed
Test switch, setup parameter, starts to test, the driving wheel of limiter of speed tester motor is erected on wheel disc, and set driving
The up-downlink direction of wheel, first make wheel disc descending, press the start button on limiter of speed tester, wheel disc court under driving wheel drive
The direction run downwards is rotated, then presses test button, and speed is continuously increased, and presses test button until electric switch moves
Make, mechanical switch action, limiter of speed tester automatic printing goes out speed.
Existing elevator governor detects the drawbacks of existing：
1st, the steel wire rope of limiter of speed side can be fixed using locking pliers, but in actual use, unavoidably
Meeting steel wire rope is caused to damage；
2nd, after steel wire rope being lifted using instruments such as nipper pliers, because steel wire rope is not flexible in itself, the steel wire rope lifted
The erection of drive device can be hindered, it is sometimes desirable to it is artificial fixed, if locking pliers is easily caused danger once disengaging；
3rd, existing limiter of speed measuring instrument needs a hand-held drive device to drive limiter of speed wheel to rotate, due to hand-held original
Cause, check results larger deviation is occurred, and great potential safety hazard be present；
4th, in-site measurement speed limit device wheel circumference adds measurement error, reduces speed limit using indirectly or with tape measure
The degree of accuracy of device detection.
The content of the invention ensures testing result accuracy and the electricity of personnel safety it is an object of the invention to provide a kind of
Terraced limiter of speed detects corollary equipment.
The concrete technical scheme of the present invention is as follows：
The present invention includes：
