Existing elevator governor responsiveness testing tool mainly contains three kinds: the first is to cooperate the method for debugging electric drill to measure the electric of limiter of speed and mechanical action speed with special-purpose speed limit table.Gauge outfit with special-purpose speed limit table during use is put in the rope sheave pitch circle groove of elevator governor, can not throw switch, and will be placed near the pitch circle position for the limiter of speed that does not have rope sheave pitch circle groove as far as possible.This kind method is artificial debugging, has error, and action numerical value is sometimes because the unexpected stop of governor sheave, and the instrument display value is the numerical value of reduction of speed, and test need to restart.
For the problems referred to above, the someone researchs and develops out another kind of testing tool again.In use, a little magnetic patch is attached to the side of governor sheave, sets initial velocity, the pitch circumference of input governor sheave starts and measures.But this kind method precision is not high, because whenever turning around, governor sheave gets a pulse signal, namely need rope sheave to turn over a complete circle, just can have pulse to read, yet it is very low in the probability of whole circle just to pause when limiter of speed moves, by linear velocity computing formula V=π Dn, can find out that the accuracy of linear velocity V and the accuracy that rotation speed n reads have direct relation, yet the most state of this tester exists following possibility, n
RealN
Survey, n
Real-n
Survey=Δ n,, and 0＜Δ n＜1, i.e. the linear velocity measuring error Δ n=π Dn of tester existence
Real-π Dn
Survey=π D Δ n can find out when Δ n infinite approach 1 and D when very large that from formula the linear velocity error of measuring will be very large.Its deuterzooid testing tool complex operation step, and do not have the storage of data to back up.
People research and develop out the third testing tool again for the problems referred to above, and by O type belt gear, the rope sheave that drives limiter of speed moves this testing tool by the driver element of bottom, are contacted with rope sheave by cranking arm by test cell and carry out data acquisition.Although this kind limiter of speed testing table has solved the subproblem that front two kinds of testing tools exist, but the test bed O type belt that adopts of this kind is nonstandard type belt, the model of limiter of speed is numerous on the market, and belt expense customized is higher, adds that there is larger technical difficulty in the connection of O type belt; Secondly belt has prolongation, must cause the speed control between driver element and the governor sheave to have certain hysteresis quality, and high velocity certainly exists larger error when measuring; Each test of cranking arm of test cell all needs artificial the adjusting to compress again, and snap-in force is changed greatly, and there is larger artificial factor in data acquisition, produces easily error.The complex operation step such as the connection of belt, mechanical arm adjustment again.Also so that this testing tool uses inconvenience.

It is as follows to adopt the test macro of present embodiment to carry out the speed characteristic test flow process:
1) will regulate stop nut 72 unclamps, move on to respectively the two ends of regulating limiting through hole 73 regulating limited block 71, then tested limiter of speed 2 is placed on the stand 5, base size according to limiter of speed 2, the mobile limited block 71 of regulating is in the middle of driving wheel 11 and the detection wheel 31 limiter of speed 2, tighten regulating stop nut 72 again, subsequently clamp nut 64 is unclamped, move forward and backward to correct position, it is tightened a compact heap 63 again and be fixed on the stationary installation movable plate 62, start clamping cylinder 61, clamping cylinder 61 piston rods descend, drive stationary installation movable plate 62 and descend, thus with compact heap 63 that limiter of speed 2 is fixing.
2) start driving wheel oscillating motor 134, driving wobble gear 131 is rotated in certain angle, the driving wheel of drive and its engagement swings tooth plate 133 and rotates around driving wheel swing tooth plate central shaft 132, the other end height that driving wheel swing tooth plate 133 is connected with live axle mount pad 161 changes, thereby adjusts the height of driving wheel 11; Adopting uses the same method adjusts the height that detects wheel 31, makes the center of circle height of driving wheel 11, rope sheave 21, detection wheel 31 identical.
3) start the cylinder that drives mobile device 15 and detect mobile device 35, driving respectively driving mobile platform 12 moves with detection mobile platform 32, impel driving wheel 11 and detect wheel 31 near limiter of speed 2 rope sheaves 21, again by driving the elastic thrust structure and detecting the elastic thrust structure and carry out the pressure adjustment; Make driving wheel 11 and detect wheel 31 and be resisted against on the rope sheave 21 with suitable pressure, 21 of rope sheaves both having guaranteed driving wheel 11, detection wheel 31 and limiter of speed 2 do not throw switch, guarantee the consistance of linear velocity between the three, the dynamic adjustments snap-in force is unlikely to excessive again, hinders the rotation of rope sheave 21.
4) start software and enter elevator governor velocity test interface, input the relevant parameter of tested limiter of speed 2, begin to enter test.
5) by computer control test overall process, and record test data is exported by output unit automatically, and deposits in simultaneously in the database, waits until the later stage and calls.
The above embodiment has only expressed the specific embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.
