Whether reach the 1st information of monitoring unit 21 inputs of overrunning of overrunning to the running velocity that monitors car 1 from rotation detector 17 and terminal floor switch 18,19.The monitoring unit of overrunning 21 is not utilized the information of operation control part 8, set the 1st and overrun but be independent of operation control part 8, and the running velocity that detects car 1 reaches the 1st and overruns.And the monitoring unit of overrunning 21 is made of the computing machine different with operation control part 8.And the power supply of monitoring unit of overrunning 21 and rotation detector 17 is supplied with the power supply supply that moves control part 8 and is separated.
The 1st overruns is configured to than the 2nd low speed of overrunning that is set by governor 13.The monitoring unit of overrunning 21 monitors the running velocity of cars 1, when the speed of car 1 reaches the 1st when overrunning, to detent 7 output brake command signal, the rotation of drive pulley 5 is braked, and promptly stops car 1.
Fig. 2 is the block scheme that the main portion of Fig. 1 is shown.In the drawings, the monitoring unit 21 of overrunning has: car position test section 22, service direction test section 23, car speed test section 24, the configuration part 25 of overrunning, relatively judging part 26 and braking instruction portion 27.
Car position test section 22 detects the position of car 1 according to the information from rotation detector 17 and terminal floor switch 18,19.In addition, car speed test section 24 uses the signal from terminal floor switch 18,19, proofreaies and correct by upper sheave 14 and the detection error that detects the rotation detector 17 that the slip of restricting between 15 etc. causes.

Car speed test section 24 detects the running velocity of car 1 according to the information from rotation detector 17.Specifically, car speed test section 24 detects the running velocity of car 1 to the time-varying information that becomes the rotation amount of upper sheave 14 from the information translation of rotation detector 17.
Overrun configuration part 25 according to from the car position information of car position test section 22 and from the service direction information of service direction test section 23, set the 1st and overrun.Relatively judging part 26 compares the 1st car speed that is detected with car speed test section 24 of overrunning that the configuration parts 25 of overrunning set, and judging has no abnormally, and promptly whether car speed reaches the 1st and overrun.When being detected by judging part 26 relatively when unusual, braking instruction portion 27 produces brake command signal and also outputs to detent 7.
Here, the square frame shown in the monitoring unit 21 of overrunning of Fig. 2 is the square frame of presentation function, and these functions are by the computer realization that constitutes the monitoring unit 21 of overrunning.That is, the overrun computing machine of monitoring unit 21 has arithmetic processing section (CPU), storage part (ROM, RAM and hard disk etc.) and signal input and output portion.Be useful on the functional programs that realizes car position test section 22, service direction test section 23, car speed test section 24, the configuration part 25 of overrunning, compares judging part 26 and braking instruction portion 27 in the storage part stored.Arithmetic processing section is carried out the relevant calculation process of function with car position test section 22, service direction test section 23, car speed test section 24, the configuration part 25 of overrunning, comparison judging part 26 and braking instruction portion 27 according to program.
Below, the 1st concrete establishing method of overrunning is described.Running speed pattern and the 1st and the 2nd figure that overruns that Fig. 3 is a car 1 that Fig. 1 is shown when the upper terminal floor normally runs to the lower terminal end floor.In the drawings, the maxim of the running speed pattern of car 1 when the upper terminal floor runs to the lower terminal end floor is highest speed mode 31 (solid line ABCDE).And the 1st overruns sets by the 1st mode 32 (single-point line IJK) of overrunning.And the 2nd overruns sets by the 2nd mode 33 (long and two-short dash line LM) of overrunning.
Highest speed mode 31 is obtained like this, that is: make the acceleration chart after operation begins near the upper terminal floor, have the maxim of the acceleration/accel of being supposed, and make the retardation curve before stopping near the lower terminal end floor, to have the maxim of the deceleration/decel of being supposed.
Yet,, can make near the deceleration/decel size of the lower terminal end floor (slope of the each point on the curve D E: 0.6m/s for example under the situation of bottom terminal floor operation (declines)
2) than the near (slope of the each point on the curve A BC: 0.9m/s of the acceleration magnitude the upper terminal floor
2) little, so that can reduce the collision velocity V of 1 pair of car buffer 11 of car
1(V
1=K).And the speed in constant speed operation area (straight line CD) is to use the maxim V that is supposed in this zone
2(for example 1.5m/s) obtains.And, in highest speed mode 31, reduce speed now from the position of lower terminal end floor switch 19.This highest speed mode 31 can be obtained alone in the monitoring unit 21 of overrunning, and irrelevant with the information of coming self-operating control part 8.
And in Fig. 3, short range velocity mode 34 (dotted line ABFG) is with the peak acceleration acceleration and at the velocity mode that reaches the maximum speed front reduction gear.This short range velocity mode 34 is made as and is running to time of run shortening under the situation of nearer floor.On the other hand, long is to quicken and the velocity mode to slow down than short range velocity mode 34 low deceleration/decels after reaching maximum speed than short range velocity mode 34 low acceleration/accels apart from velocity mode 35 (dotted line HDE).This length is made as time of run shortening under the situation that runs to floor far away apart from velocity mode 35.
In operation control part 8, according to car load and range ability, with the operation of variable maximum speed and variable acceleration-deceleration control car 1.Highest speed mode 31 is to have made the maxim of the velocity mode of various supposition like this.Therefore, the running velocity of car 1 can not surpass highest speed mode 31 usually.
Car position be in when the upper terminal floor is to lower terminal end floor switch position the 1st to overrun be to get (for example about 1.3 of maximum speed times) that predetermined surplus is set with respect to the maximum speed the highest speed mode 31 (running velocity in the constant speed operation area).And the 1st when car position is between lower terminal end floor switch position and the lower terminal end floor overrun and got predetermined surplus with respect to highest speed mode 31 and set (for example about 1.3 of running velocity times).
For example, be x when establishing car 1 deceleration distance that stops at before the lower terminal end floor that reduces speed now, the deceleration commencing speed is V
2(m/s), and the collision velocity of 1 pair of car buffer 11 of car be V
1(m/s) time, the deceleration/decel γ that can calculate according to use formula (1)
1(m/s
2) decide the 1st mode 32 of overrunning.
γ
1＝(V
1 2-(1.3V
2)
2)/(2x) …(1)
And, in formula (1), can be the distance, delta x and the deceleration distance x addition of 11 car impingement area from the terminal floor to the car buffer.And, the action of brake equipment can be postponed estimate interior, to collision velocity V
1Add surplus (Δ V
1).That is the 1st mode 32 of overrunning that can be higher, according to formula (2) setting accuracy.
γ
2＝((V
1-ΔV
1)
2-(1.3V
2)
2)/(2(x+Δx)) …(2)
Contain above-mentioned highest speed mode 31 and the 1st mode 32 of overrunning at storage part (memory device) internal memory of the monitoring unit 21 of overrunning.
More than be the situation that car 1 descends, yet under the situation that car 1 rises, set the 1st too and overrun.Promptly, when car 1 in regional of upper terminal floor switch position the time in the zone the upper terminal floor and from lower terminal end floor switch position to the lower terminal end floor, the configuration part 25 of overrunning is set the 1st according to the testing result of service direction test section 23 and is overrun.
That is, when car 1 from lower terminal end floor switch position when the bottom terminal floor is moved, set the 1st and overrun according to the above-mentioned the 1st overrun mode 32.Otherwise, when car 1 moves from lower terminal end floor side direction lower terminal end floor switch position, get predetermined surplus with respect to the maximum speed in the highest speed mode 31 and set the 1st and overrun.
And, when car 1 from upper terminal floor switch position when the top terminal floor is moved, get predetermined surplus with respect to the highest speed mode in the running of rising and set the 1st and overrun.And, when car 1 moves from upper terminal floor side direction upper terminal floor switch position, get predetermined surplus with respect to the maximum speed in the highest speed mode in the running of rising and set the 1st and overrun.
In addition, by governor 13 set the 2nd overrun mode 33 be and the 1st maxim of overrunning between get (for example the 1st peaked about 1.1 times of overrunning) that predetermined surplus is set.And the 2nd overruns is constant speed (V
3), and irrelevant with car position.
In this lift appliance, set and overrun because the monitoring unit 21 of overrunning is independent of operation control part 8, thereby the running velocity that can detect car 1 more accurately reaches and overrun, and irrelevant with the state of operation control part 8.
And, under near the situation car 1 is positioned at terminal floor, can change the 1st according to the service direction of car 1 and overrun.Therefore, under the situation that car 1 brings into operation from terminal floor, can improve acceleration/accel and make car 1 operation, can improve operating efficiency.And, car 1 in zone from the terminal floor switch position to terminal floor under the situation of terminal floor operation owing to overrun according to having the 1st of the preset deceleration degree mode initialization the 1st of overrunning, thus can earlier detect car speed unusually.
And, because car position test section 22 is according to the detection error from the information correction car position of terminal floor switch 18,19, thereby can improve the accuracy of detection of car position, can carry out the car braking maneuver more accurately.
And, monitoring unit 21 is provided with sluggish key element in the signal conditioning of the service direction that is used for detecting car 1 owing to overrun, thereby the subtle change of ignoring the service direction of car 1, thereby can eliminate the variation of the service direction that causes by interference, judge service direction more accurately.
And, by counterweight 2 for the collision permissible speed of counterweight buffer 12 as the 1st (V of Fig. 3 that overruns
1), selected counterweight buffer 12 and top clearance size (most upperstratum position place from the top of car 1 (also comprising equipment on the car) to the distance of well headroom) can make counterweight buffer 12 miniaturizations.At this moment, can be car 1 for the collision permissible speed of car buffer 11 as the 2nd (V of Fig. 3 that overruns
3) select car buffer 11 and pit depth size.

Fig. 5 is the block scheme that the main portion of Fig. 4 is shown.Overrun configuration part 25 according to from the car position information of car position test section 22 with from the service direction information of service direction test section 23, set the 1st and overrun and the 2nd overrun.Relatively judging part 26 the 1st is overrun what set by the configuration part 25 of overrunning and the 2nd is overrun and compared by the detected car speed of car speed test section 24, and judging has no abnormally, and promptly whether car speed reaches the 1st and overrun and the 2nd overrun.
When car speed reaches the 1st when overrunning, braking instruction portion 27 produces brake command signal and also exports to detent 7.When car speed reaches the 2nd when overrunning, braking instruction portion 27 produces and promptly quits work command signal and export to emergency braking device 41.
Below, the 2nd establishing method of overrunning is described.In addition, the 1st establishing method of overrunning is identical with embodiment 1.Running speed pattern and the 1st and the 2nd figure that overruns that Fig. 6 is a car 1 that Fig. 4 is shown when the upper terminal floor normally runs to the lower terminal end floor.The 2nd overruns sets by the 2nd mode 36 (long and two-short dash line LMN) of overrunning.The 2nd mode 36 of overrunning is got predetermined surplus and is set (for example about the 1st 1.1 times of overrunning) with respect to the 1st mode 32 of overrunning.
At this moment, because the 1st overrun and reduce with predetermined deceleration/decel towards the lower terminal end floor, thereby the 2nd overrun and also reduce towards the lower terminal end floor.Therefore, be V4 (V with the 2nd collision permissible speed of overrunning 1 pair of car buffer 11 of car of setting
