The specific embodiment
Fig. 1 represents that sensor is as the installation site on the escalator of one of apparatus of passenger conveyor.In addition, Fig. 2 is the lateral plan of the summary of escalator.
The escalator of present embodiment possesses: the framework 11 with approximate horizontal part of sloping portion and above and below; Be installed in the floor, gangway 1 on the approximate horizontal part of above and below of this framework 11; Mobile step 3 circulates to the below on another floor, gangway 1 from the below on floor, a gangway 1; Erect the railing of setting along the moving direction of this step 3.And the railing among the present invention is meant the part that is made of inside cover plate 18, balustrade deching 19, skirt section backplate 10 and railing panel 8.
In addition, the escalator of present embodiment is constituted as, and the inside of the part of the formation top approximate horizontal part in framework 11 is provided with Machine Room 17.And, circulate mobile synchronously by being incorporated in the handrail 9 that actuating device in this Machine Room 17 makes step 3 and be configured in the railing outer circumferential side.And, the broach part 2 that is made of broach and fishback etc. is installed in the front end on floor, gangway 1, and in the approximate horizontal part of the above and below of escalator, step 3 is by the lower surface of broach part 2, afterwards, step 3 spins upside down to circulate mobile.
Wherein, it is outstanding and when surpassing the lower end of broach part 2, if move in this state, step 3 can produce collision and broach part 2 is sustained damage with broach part 2 at step 3 certain upper surface unusual, that cause step 3 to take place.And the step 3 after also may occurring colliding is stuck in 1 place, floor, gangway and stops, thereby the situation that causes bumping in succession between the follow-up step takes place.
Above-mentioned phenomenon also might take place when having sneaked into foreign matter between adjacent step 3.Specifically, be clipped in foreign matter between the step 3 when being projected into step 3 upper surfaces, foreign matter can't be by the lower end on floor, gangway 1, and bumps with broach part 2, and broach part 2 is sustained damage.And, also may occur making step 3 stop to move because of foreign matter is clipped between floor, gangway 1 and the step 3, cause situation about bumping in succession between the follow-up step 3 thus.
Therefore, be necessary just to have occurred the moment of collision phenomenon, in time stop the circular flow of escalator at step 3.Therefore, in escalator of the present invention, adopt sensor that bump and vibrations etc. are detected unusually.Below, this method of inspection is elaborated.
After step 3 and broach part 2 collisions that are arranged on floor, gangway 1 front end, the bump that produces during this collision makes broach part 2 breakage that fractures, simultaneously, produce shake be delivered to floor, gangway 1.Detect this bump and vibrations by the sensor 4 that is installed on the floor, gangway 1, when detected value when pre-set threshold is above, stop the circular flow of escalator at once.
At this, the reason that sets in advance threshold value is, fully take into account in circular flow, the vibrations that produced in the time of not only can passenger's walking constantly occurring on the floor, gangway 1 of escalator, and can occur can not being called as the vibrations that the action of normal walking produces because of run, takeoff and jump etc.In addition, also consider under rainy day or climatic conditions similarly, be with umbrella during passenger's walking,, also have the reason of other various vibrations so may occur also that umbrella knocks and vibrations of producing etc.Therefore, the above-mentioned various vibrations mistakes that produced for fear of with so normal operation the time are judged as unusual, the acceleration levels value that is produced when normally moving is grasped as threshold value in advance, thereby can compare with the acceleration levels value that is produced when producing collision with step 3 and differentiate.So, in escalator of the present invention,, can detect the bump and the vibrations that are produced when step 3 bumps reliably by distinguishing the vibrations that produce because of other reason.
And, the acceleration/accel that step 3 and broach part 2 are produced when bumping, has the waveform that produces peak value, decays afterwards in the moment that bumps, because the time of origin of this waveform is very short, have only about 0.1～0.2 second, thus sensor 4 need be with high sensitivity, correctly detect bump and the vibrations that produce in broach part 2.Therefore, in the present embodiment, sensor 4 has been installed at 1 place, floor, gangway of clashing into and vibrations can directly be transmitted.Below, the installation site and the installation method of sensor described.
At first, detecting sensor 4 that step 3 or foreign matter and broach part 2 collide is installed on the pedestal 5 as sensor support portion.And this pedestal 5 and floor, gangway 1 are provided with through hole, and this pedestal 5 and floor, gangway 1 are supported on the framework 11 by shared bolt 6.
At this, a plurality of positions in the periphery on floor, gangway 1, be provided with the fastener hole that the bolt-through that is used for fixing with the framework 11 that is positioned at its underpart is used, the position of fastener hole is located substantially on the both sides of rear end of the opposition side that is positioned at above-mentioned front on the both sides of the front end that broach part 2 is installed on floor, gangway 1 and floor, gangway 1.Owing to sensor 4 is arranged near the position of the position of collision that collides with step 3, can be more timely and sensitivity more detect on the highland, but also sensor 4 can be housed in the inside of railing, so the fastener hole that is used for mounting base 5 is preferably placed at the front end both sides on floor, gangway 1.And, because near the bottom of the side in these front end both sides, dispose by chain from drive sprocket (sprocket) of the actuating device transferring power of escalator etc., so, consider the factors such as wiring operation of sensor signal, sensor 4 grades preferably are arranged on the railing inside with the opposite side of drive sprocket place side.But,,, can be arranged on both sides as required sometimes so the position that is provided with of sensor 4 there is no need only to be confined to a side because the purpose of sensor 4 is to detect bump and vibrations.
So, in the present embodiment, owing to utilize existing fastener hole, so on floor, gangway 1, during sensor installation 4, can not need new processing operation is implemented on floor, gangway 1.That is to say that the mounting structure of sensor 4 is simple, can reduce equipment cost.And, sensor 4 the position is set because relatively near the position of broach part 2, therefore can near the generation source of bump and vibrations, detect.
At this, because the passenger of qualified majority does not use escalator, therefore, and near passenger's walking scope, the bump that the external force that can't imagine in the time of might being subjected to because of normal walking or mischief etc. produce.And, consider that the water droplet on passenger's umbrella and the raincoat might drip under rainy day or climatic conditions similarly, so, exist especially the danger that therefore sensor 4 that is made of electronic component sustains damage.About water droplet, it is especially obvious to be arranged on the suffered influence of outdoor escalator.
, in the present embodiment, because sensor 4 and sensor support portion are covered by railing, so, even just in case the fragment that fractures that the fragment that fractures of broach part 2 or step 3 occur to around unrestrained situation, cause direct injury also can not for sensor 4, so proper.Below, with reference to Fig. 3 the structure around sensor 4 and the sensor support portion is elaborated.
Railing is positioned at the top of floor, gangway 1 front end, as shown in Figure 3, as inside cover plate 18, balustrade deching 19 and the skirt section backplate 10 of its member round the upper surface of pedestal 5 and side and be provided with.And skirt section backplate 10 has adopted and can be installed in structure on the L shaped steel by screw 21, and therefore, when mounting base 5, railing can be pulled down or load onto easily.According to said structure and since sensor 4 the position is set not in passenger's the domain of walk, be subjected to unexpected damage so can prevent sensor 4.
Then, as detecting the unusual concrete sensor 4 in inlet floor 1, can enumerate acceleration pick-up.In recent years, along with the development of MEMS technology, the chip of subminiature this kind acceleration pick-up that can buy with very cheap price in market, it has very high sensitivity.The quantity of the axis of acceleration sensing of sensor 4 is different because of model, and has fixing induction direction.In general, because between the induction direction and non-induction direction of acceleration pick-up, its transmission characteristic differs about 20～40dB, on the grade of acceleration/accel, produce 1/10～1/100 poor sensitivity, thus the vibrations that produced when being necessary to aim at the induction direction of sensor 4 with step 3 collisions apply direction.When being installed in sensor 4 on the floor, gangway 1, be existing fastener hole owing to what use, so fastening direction and its aperture and employed bolt size all are fixed in advance.Therefore, for the induction direction of sensor 4 being adjusted to the direction of regulation, adopting by pedestal 5 and be installed to mode on the floor, gangway 1.
Below, with reference to Fig. 4 the installation method of sensor in the present embodiment 4 and pedestal 5 is described.In the present embodiment, adopted sensor 4 has been installed in the such structure in pedestal 5 sides, specifically, be that chip with sensor 4 is fixed on the sensor base plate 7, by screw 12 secure components such as grade this sensor base plate 7 be installed in then and be positioned on the mount pad of side of pedestal 5 that above-below direction has through hole.And, in the time of on being installed to floor, gangway 1, the detection side who makes sensor 4 to step 3 and the corresponding working direction keeping parallelisms of generation direction bump and vibrations and consistent.
At this moment, the size of pedestal 5 is preferably a little bit smaller as far as possible.This be because, because the sensitivity of sensor 4 is very good, so if pedestal 5 is too big, then the resonant frequency that sensor 4 might sensor support portion also detects.In general, the resonant frequency of acceleration pick-up self is in the frequency range of very high dozens of KHz, is being in the frequency range of purpose to detect bump, and the resonant frequency of sensor support portion self can not become problem., when the resonant frequency of sensor support portion is in lower frequency range, when for example being about in the band limits about 1000Hz, the sensitivity of sensor 4 may be subjected to the influence of sensor support portion.Therefore, height dimension as the pedestal 5 of sensor support portion preferably is controlled in the scope of necessary minimum, specifically, the height dimension with pedestal 5 is set at: the bolt 6 that uses when it is installed on the floor, gangway 1 can by and with the essentially identical size of installation dimension of the sensor base plate 7 of fixation of sensor 4 chips.And the shape of pedestal 5 there is no need necessarily to be confined to cube shown in Figure 4, as long as can hold-down bolt 6, can guarantee the sensor signal lines needed sensor attachment face that connects up, and then Any shape all can be used.
In addition, in general, because the sensitivity of sensor 4, no matter be with the side as attachment face, still with upper surface as attachment face, all can not produce difference, so attachment face there is no need necessarily to be confined to the side of pedestal 5, and can be with the upper surface of pedestal 5 as attachment face.Therefore, Fig. 5 represents is embodiment when the upper surface of pedestal 5 is used as the attachment face of sensor 4.In this embodiment, the bolt-through hole face of pedestal 5 and the attachment face of sensor base plate 7 are identical faces, in the time of on being installed in floor, gangway 1, its installation form be installed in the side on the time the same, the detection side who makes sensor 4 to step 3 and the corresponding working direction keeping parallelisms of generation direction bump and vibrations and consistent.
As mentioned above, because by sensor 4 is set in the space that surrounds by railing, sensor 4 can be arranged on beyond passenger's the domain of walk, when normal operation, be subjected to unexpected external force injury, can prevent that water droplet etc. from directly dripping on the sensor so can prevent it., because sensor 4 is installed into from sensor base plate 7 and exposes,, also can adopt by protective case 13 sensor 4 and pedestal 5 are all covered the structures of getting up so consider and make provision against emergencies.
Fig. 6 represents the structure of protective case 13.This protective case 13 is made of thin plate, and it is formed the upper surface that encases pedestal 5 and the shape of side, when mounted, covers whole pedestal 5 from the top, with other bolt 14 it is fastened on the upper end and sets in advance in the bolt 6 of bolt hole.Above-mentioned protective case 13 as shown in Figure 4 and Figure 5, even the shape difference of pedestal 5 also can adopt same installation method to install.And, because protective case 13 self is set in the space that is surrounded by railing, can directly not suffer very strong external force, so there is no need to be arranged to strong design, the easy structure that assembles with thin plate just can achieve the goal.
By adopting above-mentioned such protective case 13, can prevent reliably further that sensor 4 from sustaining damage.And, just in case need keep in repair sensor 4 time, can take off protective case 13 just only need bolt 14 removed, therefore, do not need to pull down pedestal 5, just can confirm sensor 4 easily.
And the acceleration pick-up that is adopted in the present embodiment not only can detect the collision phenomenon of step 3, rocks because of seimic but also can be used in detection, when earthquake degree is high, can make safety device action and out of service.When being used to detect earthquake, not only to considering to protect sensor avoiding being subjected to the influence of passenger's walking, but also need be fixed on the crash-resistant parts by degree of will speed up sensor.At this moment, shown in the present embodiment to utilize framework 11 to support the structure on acceleration pick-up and floor, gangway 1 together effective too.
And, in above-mentioned present embodiment,, in as the speedwalk of one of apparatus of passenger conveyor, also can adopt same structure though be that example is described with the escalator that produces difference of height between the pedal.Therefore, the connotation that also comprises the pedal among the speedwalk in this term of step as used in this specification.
