Conventional elevator governor operation test equipment was configured as above, so when measuring the operating speed of this governor, if the governor's rotational speed was rapidly accelerated and measured, The internal mechanism of the speed governor is unable to follow the acceleration due to inertia, causing a delay and detecting a value larger than the actual operating speed. Therefore, when making measurements, it is necessary to gradually accelerate the rotational speed of the governor to a predetermined operating speed. However, there was a drawback that gradually accelerating the governor required a very long time for operation tests.

で増幅し、電動機２に印加している。 A drive roller 4 is installed on the shaft of an electric motor 2, and this drive roller 4 and a speed detection device 3 are pressed against a sheave 1 of a speed governor. A control device 5 controls the speed of the electric motor 2, and this control device 5
A resistor 6 and an operational amplifier 9 are connected in series, a capacitor 8 is connected in parallel to the operational amplifier 9 to form an integrating circuit, and the circuit is connected in series to a power supply E via a normally open contact Sa of a switch (not shown). ing. In order to change the resistance value of the resistor 6 of the above-mentioned integrating circuit as necessary, the normally open contact 7b of a relay (not shown) that detects the speed from the speed detector 3 is connected in parallel to the resistor 6 so that at least a part thereof is short-circuited. It is connected. The voltage thus controlled is transferred to the amplifier 10.

Turn off the control circuit. At time t3 when the catch operating speed is V3 , the catch can be operated to stop the governor.

速機の設定速度V1に達する時間t1まで急速に加速
することができる。 When the resistance value of the resistor 6 is R and the reactance of the capacitor 8 is C, the output voltage v of the integrating circuit is v=E/CRt (1). As is clear from equation (1), when the switch is turned on, its contact Sa is closed, and the output voltage v increases proportionally with the slope of E/CR with respect to time t. At this time, the normally open contact 7b remains closed, so the resistance value R becomes small, and rapid acceleration can be achieved until time t1 , when the speed governor's set speed V1 is reached, as shown in FIG.

opens. As a result, a resistor is inserted between the power source E and the motor 2, the resistance value R becomes large, and the output voltage v
The slope E/CR becomes gentle, and the speed can be accelerated to a predetermined governor operating speed. Thereafter, as shown in FIG. 2, when the governor operating speed V 2 is detected at time t 2 , the control circuit is turned off and the governor operation test can be performed. Further, when the speed of the speed governor becomes excessive, the catch operating speed V3 is detected at time t3 , the catch is operated, and the speed governor can be stopped.

急速に加速させると更に効果がある。 The speed of the governor was gradually increased from the set speed V 1 to detect the governor operating speed V 2 and the catch operating speed V 3. However, after detecting the governor operating speed V 2 , the resistance It is even more effective to short-circuit V 6 with a normally closed contact to rapidly accelerate the catch operation speed before reaching V 3 .
