The specific embodiment
(embodiment of inspection method)
Fig. 1 is the integral structure figure of check system of the elevator emergency stop device of one embodiment of the invention.
Top and the bottom in the left and right side of lift car 1 are equipped with guide roller 2 (2U, 2L), and by the guide rail 4 (4L, 4R) that on the whole length of above-below direction, is arranged on the left and right sides of hoist trunk 3 to this guide roller 2 (2U, 2L) channeling conduct.Lift car 1 goes on above-below direction along guide rail 4 under the driving of not shown drive motor.
Be equipped with on the guide roller 2L of lift car 1 downside through embracing guide rail 4 and come emergency braking device 5 that lift car 1 is braked.
On the high position than guide roller 2U of lift car 1 upside, speed sensor 6 is installed.As speed sensor 6, can adopt electromagnetic wave irradiation on the surface of guide rail 4, and utilize this electromagnetic backward wave to come the speed sensor of detection speed and come speed sensor of detection speed etc. through reading the continuous sign that is installed on the guide rail 4.In the present embodiment, so that be combined into example and describe with the field of electromagnetic wave irradiation type sensor.And, with the surface of guide rail 4L detection faces as speed sensor 6.In addition, the detailed installation method of speed sensor 6 will after state the part describe.
The output of speed sensor 6 is imported in the control setup 7.Control setup 7 carries out signal conditioning through the output signal to speed sensor 6 and obtains speed.Meanwhile, outputed among the terminal 9a of the terminal disc 8 that is arranged on lift car 1 top with the proportional electric signal of speed.In addition, the output form when outputing to terminal 9a promptly can be and analog signal such as the proportional electric current of speed also can be the digital signal that the data by the number bits constitute.In addition, also can obtain detection speed, at this moment, can directly velocity information be outputed to control setup 7 and the terminal 9a from speed sensor 6 in speed sensor 6 inside.
The maintainer can make lift car 1 move at above-below direction with manual mode through being arranged on the pullswitch (pendant switch) 12 that when maintenance moves, uses on lift car 1 top.In addition, in the check system and inspection method of elevator emergency stop device of the present invention, preferably be arranged to the personnel of not needing repairing and take advantage of, can with manual mode lift car 1 moved at above-below direction in the Machine Room into lift car.
Elevator setting is become can lift car 1 be run to the upper part of hoist trunk 3 through maintainer's M/C, and make on its position that stops at regulation.Be specifically, limit switch 10 is installed in the upper part, and the cam 11 of pushing limit switch 10 when elevator cage operation during to the position of stipulating is installed in lift car 1 side.When being pressed, limit switch 10, lift car 1 is stopped to control setup 7 output danger signals.So; With from the Machine Room or keep in repair operation through pullswitch 12 and the time compare; The relative importance value that stops that being undertaken by limit switch 10 is set De Genggao, and thus, lift car 1 remains on the identical position at the stop position of the top of hoist trunk.
On the higher position, the position of guide roller 2U when the upper end that guide rail 4L is arranged to this guide rail 4L is positioned at and stops under the effect of limit switch 10 than lift car 1.And speed sensor 6 is installed in than guide roller 2U height and than on the also high position, the upper end of guide rail 4L.And on the extended line of guide rail 4L, the height and position place identical with speed sensor 6 is provided with the disk 13 as the analog rate generation unit, and the S. A. of disk 13 is fixed in the hoist trunk 3.In addition, on the S. A. of disk 13 installing drive with electrical motor 14.
Above-mentioned disk 13 is arranged to have the detection faces identical with guide rail 4 with respect to speed sensor 6, makes that the condition of condition when detecting moving velocity through the surface of disk 13 when speed sensor 6 detects rising or falling speed through the surface of guide rail 4 is identical.In addition, also can generate the analog rate identical, replace disk 13 with this through making endless belt rotation with disk 13.If adopt the speed sensor read the type that is installed in the continuous sign on the guide rail 4 during, same sign also is set in the front of disk 13 as speed sensor 6 again.
In addition, if the top of hoist trunk 3 does not have the space, the position that disk 13 then can be set will be restricted.In this case, have to reduce the position that is provided with of disk 13, its result, when lift car 1 moved to the superiors, speed sensor 6 was temporary transient through the gap between guide rail 4L upper end and the disk 13.At this moment, this gap portion becomes the dead angle area of speed sensor 6, and speed sensor 6 temporarily detects less than speed in this dead angle area.If control setup 7 has been made erroneous judgement in this time, judge that fault has taken place speed sensor 6, and lift car promptly stopped that then lift car can't rise to the topmost portion of regulation in order to guarantee safety.For fear of above-mentioned misoperation occurring, hide these gaps through hiding member 15, be controlled in the Min. with the dead angle area that will arrive in the zone till the superiors.And through software processes, what make the speed sensor 6 that takes place on the height and position to dead angle area ignores processing unusually, makes lift car can move to the position of the superiors and disk 13 with this.In addition; Just in case the situation that lift car 1 begins to fall when speed sensor 6 is positioned at dead angle area has taken place; Surpassed this situation of specified speed because speed sensor 6 detects on can the position after walking out dead angle area, can make emergency braking device 5 actions, thereby lift car 1 is stopped.Because dead angle area has only several mm, so even elevator begins to fall in this part, speed also can rise hardly, so lift car 1 is stopped safely.
Position transduser 27 (Fig. 2) as control setup 7 is provided with for obtaining location information can use the conventional device such as locational position detector that are arranged on the limit switch in the hoist trunk or are arranged on each floor equally with the terminal floor forced deceleration with switch.In addition, detect continuous position if desired, then can use measurement mechanisms such as laser rangefinder or magnetic deformation line formula position transduser.

Fig. 2 is the schematic configuration diagram of control setup 7 of check system of the elevator emergency stop device of one embodiment of the invention.
The impulse singla of control setup 7 input speed sensors 6, and through speed operational part 71 arithmetic speeds.On the other hand, when above-mentioned switch 17 is ON, through speed inspection signal generation portion 72 formation speeds inspection signal.To from the inspection signal of this velocity amplitude or speed, select through change-over switch 73 one with the velocity ratio of regulation, and detect the unusual speedup of lift cars 1 by unusual speedup test section 74, generate thus and promptly stop action command.
Specified speed is according to the set positions of lift car.That is to say; By the position of elevator car position test section 75 according to the output computing lift car 1 of elevator car position sensor 27; And the elevator car position that obtains is input to specified speed configuration part 77 via change-over switch 76 (left side), set and elevator car position relevant provisions speed thus.For example, when lift car 1 is positioned at the centre portion of hoist trunk 3, the specified value of speed is set for before the speed of lift car 1 surpasses 1.4 times of command speed make emergency braking device 5 actions.Relative therewith, at the terminal part up and down of hoist trunk 3, lift car 1 slows down in order to stop terminal floor, so the terminal part up and down of hoist trunk 3 is low cruise zones of lift car 1.Therefore, set the specified value of the speed of terminal part up and down lower than command speed.
As stated, control setup 7 is according to the specified value of the set positions speed of lift car 1, and when the velocity amplitude of lift car had surpassed the specified value of speed, control setup 7 outputs promptly stopped the action command signal, so that emergency braking device 5 actions.In order to check the output state that promptly stops the action command signal of this moment, in the terminal disc 8 of lift car 1, terminal 9c is set.
In the check system of this elevator emergency stop device; Speed sensor 6 and disk 13 relatively to state under; Make disk 13 rotations through drive motor 14; And compare through the speed to this rotative speed and speed sensor 6, can confirm the speed accuracy of detection of speed sensor 6.In addition, through improving the rotative speed of drive motor 14 gradually, for example can confirm when 1.4 times of command speed speed, whether to have exported and promptly stop the action command signal.
And; The inspection signal of formation speed in control setup 7; Speed when promptly stopping the action command signal output with set a plurality of because of the relation between the different and different specified speed of elevator car position, whether the speed in the time of can confirming promptly to stop the action command signal output normal.
In addition; In order to check; Analog signal and the data logger 28 of digital signal and the device of correctly confirming lift car 1 position of the speed gauge 24, stored voltage etc. of the rotative speed of the circular velocity of measuring disk 13 or axle need be set, and this device for example can be a laser rangefinder (not shown) etc.

A. (not shown) of speed gauge 24 is connected on the axle of disk 13.In addition, also can adopt make speed gauge 24 rotating part (speed input part) by the method for velocity of measuring disk 13 on the periphery that is pressed in disk 13.
After above dead work is accomplished, make data logger 28 opening entries, by drive motor 14 driver plates 13 and begin to measure.Produce analog rate through disk 13 is rotated, and make speed sensor 6 detect analog rates.The concrete grammar that makes disk 13 rotation through drive motor 14 after state part and be elaborated.
At last, estimate the accuracy of detection of speed sensor 6.Obtain standard analog speed according to the observed reading of speed gauge 24, its detection speed with the speed sensor of measuring through terminal 9a 6 is compared.Then, both velocity contrast as error, and is confirmed whether this error is in the allowed band.
The inspection step of confirming the precision of speed sensor 6 leaves it at that.
Below the inspection step of the responsiveness of emergency braking device 5 is described.As stated, because the specified value of speed is different because of the difference of elevator car position, so repeat following inspection in a plurality of positions.
At first,, lift car 1 is risen, till limit switch 10 stops lift car 1, then speed sensor 6 is moved to the height of disk 13 through pullswitch 12.After this, data logger 28 is set, the preparation of measuring.The terminal 9a of the detection speed signal that connection generates according to the output of speed sensor 6 and the analog input terminal of data logger 28.In addition, the digital input end of the terminal 9c of the output state that promptly stops the action command signal of splicing ear dish 8 and data logger 28.The lead-out terminal of while connection speed meter 24 and the analog input terminal of data logger 28.After this, in order to measure the speed of disk 13, the S. A. (not shown) of speed gauge 24 is combined on the axle of disk 13.
In the present embodiment, generate the position detection signal through control setup 7, under the unactual situation about moving of lift car 1, whether the speed of each when the affirmation emergency braking device moves in the different position of hoist trunk is normal.For this reason, in control setup 7, load and generate the program that the position detection signal is used, and in switch case 16, set up the required switch of implementation program 18.In addition, further set up the button 19 that the position of selecting generate this moment is used.Change the position of lift car 1 through pressing this button 19 with simulating.
Connect at switch 18, and change-over switch 76 is when being switched to the right side, control setup 7 is ignored actual location information, and comes the setting speed specified value according to the position detection signal.That is to say that elevator car position inspection signal generation portion 78 generates and the corresponding elevator car position inspection of the elevator car position of selecting through button 19 signal, and it is outputed in the speed setting portion 77 of regulation.
Thus, through software simulation ground lift car 1 is moved to the inspection position of regulation.
Above dead work makes data logger 28 opening entries after accomplishing, through drive motor 14 driver plates 13, to begin measurement.Generate analog rate through disk 13 is rotated, and make speed sensor 6 detect analog rates.
Owing to set the position of lift car 1 through button 19, so, have and the corresponding different value of the elevator car position that sets by the speed of the regulation of speed setting portion 77 outputs of regulation.
Improve the rotative speed of disk 13 gradually, when this rotative speed had surpassed the speed of regulation, generation promptly stopped action command.Whether the speed of confirming speed gauge 24 at this moment is consistent with the car speed that promptly stops the action command generation through should make on the elevator car position of button 19 settings, consistent like speed, then finishes the inspection of this desired location.
As required, through the setting of button 19 change elevator car positions, can confirm promptly to stop the normality of action command once more at different elevator car positions.
