Description

The operating control that is used for the drive element of a person conveyer

The present invention relates to a kind of to a kind of person conveyer, the device handled of the drive element of escalator especially.

As everyone knows, on a kind of escalator, after a sensor that is located in the stretcher zone is experienced the pressure that is carried on the stretcher, just start drive motor, drive motor is switched on by a control relay.Stretcher is downward through subsiding after certain stroke, and this also can make troubles therefore for the user of escalator except itself can bring recurrent noise.

Be located at outside the person conveyer, be used to handle the acoustic control of driver element or light control system, thereby in face of artificial destruction, can not be adequately protected owing to be touched easily.

The objective of the invention is to a kind of operating control that is used for the drive element of a person conveyer is so designed, on the one hand avoid it to be subjected to artificial destruction, on the other hand with stretcher do not expect that the sinking that takes place is limited in minimum level.

The objective of the invention is by a kind of a kind of person conveyer, especially the device handled of the drive element of escalator is realized, wherein, in the inlet and/or exit region of person conveyer, at least be provided with the light wave guide that an energy is reacted to pressure, the covered laying of this light wave guide also is connected with at least one analysis circuit.

Other favourable improvement design of the present invention is provided by dependent claims.

A contact member that is made of at least one light wave guide and especially is located in the involucrum is adopted in suggestion.By its effective on-off element that is connected at least one actuating device that constitutes person conveyer, especially an escalator with at least one analysis circuit.

Light wave guide or its involucrum preferably are arranged in the stretcher zone, especially are located in the lid zone, hole of escalator.

The visual applicable cases of light wave guide that is held by involucrum has different profiles.But light wave guide for example is laid in the band (Streifen) straight-line extension like this, perhaps with its serpentine bend be located in the planar element.

For escalator, light wave guide or its involucrum are designed to the tape shape and only are arranged on the hole cover in the zone just enough.

Equally also can consider to adopt light wave guide as requiring elevator or opening the triggering element of cage lifter door.

The special applications field of light wave guide respectively is the drive motor that is used to start or close down an escalator, at this moment, a pressure that acts on light wave guide or its involucrum changes by light wave guide being flattened make it to stretch, impel the analysis circuit that is connected on after this light wave guide to trigger corresponding contact, to start or to close down drive motor.

Light wave guide, the involucrum that especially holds it can be used as pressure sensor, and wherein, the variation of the optical transmission performance of this light wave guide can be regarded the response criteria of described analysis circuit as.

Can carry out pre-programmed to described analysis circuit at different basic load situations, that is calibrate.This will consider light wave guide, or the banded or planar involucrum that holds it is located at the situation under the Different Weight material.

Like this, for example when adopting light wave guide of the present invention and, in the time of may also having its involucrum to be arranged in the inlet of an elevator and/or the exit region, for example can adopt the marble slab floor or only be PVC (polyvinylchloride) layer it.These material requirements analysis circuits are having different align modes to the pre-timing of certain baseload, but also will consider that certain permissible tolerance is arranged, so that driver element can not be activated or close down under the very little situation of fluctuation of pressure.

Application of the present invention is very extensive.Light wave guide is surrounded interior involucrum or sleeve pipe also various structure can be arranged.

By the accompanying drawing illustrated embodiment the present invention is further described below, in the accompanying drawing:

Fig. 1 is the basic sketch of the entrance area of an escalator (Rollsteige);

Fig. 2 is the local diagrammatic sketch of the entrance area of an escalator (Rolltreppe);

Fig. 3 is the cross sectional drawing along the A-A line of cut among Fig. 2.

Fig. 1 is the basic sketch of the entrance area 1 of an escalator 2, therefrom mainly can see following member:

One is opened wide hole 3, one drive motor 4 that illustrate and is located in this hole in sketch.Drive motor drives base plate 5 on the one hand by variable-speed drive not shown further (along the direction of arrow) among the figure, drives the handrail 6 of escalator 2 on the other hand.Hole 3 is limited by a framework that only schematically shows 7.Not shown hole lid can be laid on this above framework and fixed.

A light wave guide 8 that is held by unshowned involucrum is installed on the framework 7 with strips, also can be bonded in when needed on the framework 7, and light wave guide is being located under the running state of escalator 2 between the lid of framework 7 and hole not shown further like this.Look applicable cases, can substitute daylight with an independent light source 9, so that provide light to light wave guide 8.Light wave guide exports 10 places at it and effectively is connected with an analysis circuit 12 by a signal conductor 11, and this analysis circuit 12 can be the component part of higher level's master control system when needed.It can be connected with drive motor 4 by a microprocessor control and by another root lead 13.

Not shown hole lid forms a pressure to light wave guide 8, and it is stored in the analysis circuit 12 as so-called basic load.Now tolerance load of stack on the basic load when having covered very little load in the hole like this, is not just worried can so starting drive motor 4.Only really be used for the conveying personnel, having a pressure that exceeds above-mentioned load (basic load+tolerance load) to act on the hole covers, when making the distortion of light wave guide 8 or its involucrum, because the optical transmission performance of light wave guide changes, described analysis circuit just can respond and start drive motor 4 by lead 13.Can pass through a frequency converter (not shown) controlling and driving motor too technically, base plate 5 and handrail 6 are under low speed wriggling (Schleichgang) pattern, can finish the low speed stroke and produce normal gait of march by analysis circuit 12 like this.

At the unshowned outlet area of escalator 2, the start-up course of drive motor is undertaken by opposite mode, acting on this moment and cheating the pressure signal that covers is the criterion of closing down drive motor.But in the day-to-day operation of escalator, close down drive motor and but do not play an important role, use escalator, must consider to adopt other criterion, use so that make escalator aspect switch performance, can obtain rational and effective because have many people.This can be achieved like this under indivedual situations, promptly closes down drive motor according to condition of loading by a time relay.This process must be complementary with the equipment that is adopted at that time in the corresponding way.

Fig. 2 is the ditch hole 3 local diagrammatic sketch together with framework 7.Therefrom can see drive motor 4 and signal conductor 10 and pilot 13 and light wave guide 8, light wave guide 8 is meander extension on framework 7 snakelikely in the present embodiment, so that produce an increased pressure face with method by this way.Light wave guide 8 is centered on by an involucrum 14, to constitute a band.

Fig. 3 for along the line of cut A-A among Fig. 2 cut open cross sectional drawing, wherein also show the hole cover 15, promptly so-called base plate cover.From Fig. 3, can also see framework 7, light wave guide 8, light source 9, analysis circuit 12 and drive motor 4.Light wave guide 8 is installed in the involucrum 14.The restriction that this involucrum is used can be made by various material, and for example it can be made of plastic herein.Involucrum 14 can be by being pasted and fixed on the framework surface 16.But also can consider other fixing means or guidance means.Utilize a kind of photometric characteristics of being scheduled to of light source 9 feed-in in light wave guide 8, simultaneously this signal is offered analysis circuit 12.Act on hole on involucrum 14 or the light wave guide 8 and cover 15 weight and be stored in the analysis circuit 12, also be provided with a limit tolerance range (tolerance limit) simultaneously, to prevent starting drive motor 4 unintentionally as basic load.Only when surpassing this limit tolerance range, for example when personnel stand on the operculum colpi 14, just have a kind of like this pressure p to act on the operculum colpi 14, that is, it can make the photometric characteristics of the light wave guide 8 that is designed to glass fibre change.This can cause described signal to change again, and the analyzed circuit 12 of this variation detects, analysis circuit 12 and then can start drive motor 4 or its low speed that may exist from one wriggling stroke is transformed into the normal transmission power stroke.
