Description

Clean-up device and clean method

The present invention relates to a kind of device that is used for the pedal of mechanical cleaning escalator or raceway as described in the preamble as claimed in claim 1, also relate to a kind of corresponding automated cleaning method, and a kind of method of pedal that is used to clean escalator or raceway of being furnished with controllable drive mechanism, also relate to a kind of device that is used to carry out said method.

DE 195 39 186 A1 openly cross as claim 1 a kind of clean-up device that are used to clean escalator or raceway pedal as described in the preamble.According to this design, pedal surface and end face in order to clean these steps have adopted a kind of brush, but it is made of a driving belt that is fixed with the circular flow of brush ranks on it.This belt has the loading of a level in the section on step pedal surface, and a vertical loading is in the section of step end face.In addition, this device also is furnished with some nozzles, be used for ejecting a kind of washing lotion from a holding vessel, also be furnished with a storage vessel that is used for collecting addle, this addle is to be placed in the absorption plant of effect highway section end and to be fed to this collection container through one.After first lower step was finished the clean operation process, this device was just little by little up promoted on one-level one-level ground by a lift system and bit manipulation personnel, and in time is parked in corresponding place, carries out a new clean cycle.Therefore, generally speaking, this device must move up, and this is a kind of pretty troublesome thing, and finally also may jeopardize operating personal.

Design as the cleaning element of circular flow brush band often causes producing result unsatisfactory, especially uses on escalator, because the angular region between the pedal surface of step and the end face normally can not be cleaned fully.Therefore used brush can not obtain sufficient cleaning effect, especially in above-mentioned debatable place because the restriction of its support fixation can not or can only partly reach the angular region.Replenish cleaning at these local also handy hands usually later on.For clean-up device being moved a pedal forward, must guide by hand, thereby always need bit manipulation personnel on the scene, this has just increased the weight of the difficulty of economical use.

According to above-mentioned situation, task of the present invention provides a kind of improved device and a kind of improved method, with the cleaning of the pedal that is used for escalator or raceway, so as to guaranteeing to realize completely a kind of and clean operation automatically basically.

Above-mentioned task is to adopt above-mentioned clean-up device with feature of characteristic in the claim 1, and by having a kind of method of feature described in the claim 20, solves.

Various preferred versions are contents of dependent claims.

Because the device of being furnished with cleaning element can be roughly parallel to pedal surface by mode of oscillation and be driven, that is to say can be according to crank motion parallel motion on pedal surface automatically, so can guarantee to realize the thorough cleaning of pedal all sites.This point concerning those have the escalator and raceway of groove line profile, is very favourable especially, because here foul and sediment can accumulate in those grooves at an easy rate.Cleaning is got up very difficult.Especially when escalator is cleaned, follow the clean operation of vibratory movement to make cleaning element can reach the angular region always, the i.e. angular region that forms between the end face of a step and next higher step, thus this angular region also can be enough to gratifying cleaning.

According to a favourable scheme of this clean-up device, the mechanism and the horizontal vibratory movement of carrying each cleaning element also can oscillatorily be driven according to vertical direction synchronously.Because this form of implementation of clean-up device, a kind of horizontal motion of vibration can synchronously be superimposed with the perpendicular movement of vibrating, so by each circulation, cleaning element at first descends on the surface of pedal, when contacting, be withdrawn then with pedal surface, be lifted once more subsequently, and above the pedal surface of pedal, get back to drop point once more.Like this, be pushed foul and sediment the trough of belt line profile and shift out, make foul can not kicked up, but be open along a direction along a direction from the pedal of escalator or raceway.Because cleaning element repeatedly skims over the surface that is cleaned by vibratory movement, thereby all sites that has guaranteed pedal is cleaned completely.

The horizontal vibratory movement of cleaning element can be implemented like this, makes that only some is capped on surface to be cleaned.Can be supported on the pedal surface so carrying the mechanism of cleaning element with regulating, make this mechanism little by little when implementing vibratory movement, be pulled through pedal surface.Owing to shortened the path of vibratory movement in such a way, thereby obtained stronger cleaning effect.

Cleaning element not only can be used to clean the plate surface of escalator, and can be used for cleaning the end face of the step of escalator.Yet particularly advantageously be, dispose the second specific cleaning element, for example adopt a kind of form with pad of adsorption power, these pads act on the end face of step, and wherein mechanism also can vertical direction regulate.Especially under the situation of cleaning escalator, can reach following purpose: the foul on the step end face can be cleared away and be adsorbed.As also will illustrating below, above-mentioned pad can be automatically in a collecting tank scrub in addition.

In order when cleaning escalator, to clean the position, angular region better, preferably use cleaning brush as the cleaning element that is used for pedal surface, these cleaning brushs extend perpendicular to the sense of motion of escalator.

Do not disposed if each cleaning device is not the width according to pedal, after having cleaned certain part of a pedal,, perhaps it is passed in the clean-up device so just clean-up device can be moved on one side.But, particularly advantageous way is that cleaning element extends the width that surmounts escalator a little.

In order to guarantee that cleaning member has long service life, need not change, can dispose some nozzles and/or a collecting tank that preferably has a sleaker, so as between each operation, cleaning element being cleaned.Configurable for this reason for example such mechanism, this mechanism can come the hydro-peening cleaning member by nozzle in other words on a sleaker.

Specifically, under the situation of the escalator of being furnished with controlled actuating device and raceway, the task that the present invention proposes also can be by adopting a kind of method with the feature in claim 25 characteristic, and adopt a kind of device with feature described in the claim 34 to solve.

Preferred version also is the content of the dependent claims relevant with the aforesaid right requirement.

Because the actuating device of escalator or raceway can be controlled by the signal that the control system of clean-up device is sent, so clean-up device itself can draw escalator, for example one-level one-level ground traction intermittently, therefore, cleaning process can automatically be carried out by the electronic communication between clean-up device and the control system for escalator, and without any need for operating personal.Clean-up device by the present invention proposes also are provided with a joint, to be used to connect the control system of escalator or raceway for this reason on the control system of clean-up device.

A kind of like this method and a kind of like this device make clean-up device after having cleaned the pedal of predetermined number, can control escalator, so that escalator continues to move forward the pedal of predetermined number.When the pedal to a certain number cleaned, clean-up device were on the same position, and escalator or raceway then continue operation.This operation is to be triggered by the signal that the control system of clean-up device is sent.Therefore, there is no need by the step clean-up device that move up at all.By the direct automated communications between escalator or raceway and the clean-up device, can realize a kind of full automaticity cleaning procedure.

According to a preferred version, clean-up device are moved to an end of escalator or raceway, and the driving control system of escalator or raceway is to link to each other with the control system of clean-up device.The pedal surface of first number then, for example a pedal surface is cleaned with clean-up device.After the clean operation process was finished, the control system of clean-up device was sent a signal to the driving device controls system of escalator or raceway, made escalator move forward the pedal with the first number respective number, so cleaning course can restart again.

Clean-up device only need be located the lower end that for example is positioned at escalator once by an operating personal, and all the other every operations can automatically perform, and obtain clean up to whole escalator.

The control system of clean-up device with being connected of actuating device of escalator or raceway can utilize the interface cable of a corresponding coupling to realize.

In view of the above, particularly advantageously be, the clean operation process is according to the described method of claim 18 to 20, perhaps utilizes a kind of clean-up device described in each of claim 1 to 19 to carry out.When clean-up device were used for escalator, particularly advantageous was except the pedal surface of cleaning step, also can clean the end face of step.For this reason, the control system of clean-up device is so being controlled escalator, makes at least one end face expose, and after the pedal surface clean operation or before still can clean an end face.

For each end face is cleaned, preferably adopt a kind of clean method described in one of

claim

23 and 24.

A preferred construction form showing the clean-up device of understanding that the present invention proposes in the accompanying drawings, the clean method that also will propose in conjunction with the present invention is illustrated it below.Accompanying drawing is represented:

Shown in Fig. 1 to 3 all with 11 the expression clean-up device, be used to clean the pedal step 2 of an escalator 1, it basically by one be placed in one movably in the shell 12, can be vertically and the hold-down arm 13 of horizontal adjustment constitute, on this hold-down arm, disposed one tappet 14

cleaning element

61,62 and that can drive by mode of oscillation be housed.Therefore

cleaning element

61,62 can repeatedly act on the pedal surface 3 or the end face 4 of each pedal step 2, and the foul on it is disposed.The cleaning element 61 that is used for pedal surface 3 is perpendicular to the brush row that plan is settled, and these brushes are listed as in the profile of the trough of belt line that also can be embedded into pedal surface effectively.The cleaning element 62 that is used for end face 4 is as the cavernous body design-calculated.

In order to make clean-up device 11 automatically be on the operating position, configuration two rollers 21 and one or two adjustable for height power wheel 22 on an end of the shell 12 of being furnished with handle 20, adjustable roller 26 and one or two conversioning wheel 29 of configuration height then in the end of face-off.In order to drive power wheel 22, disposed one since come into plain view so do not show bright electrical motor in the drawings.Tooth

bar

23 and 27 is used for the height adjustment of power wheel 22 and roller 26, and these two tooth bars can pass through an electrical motor 24, through the drive gearbox 25 of an attaching on this electrical motor, perhaps directly by an electrical motor 28, is regulated.In addition, hold-down arm 13 can also utilize the driving motor 17 of an axle 16 and an attaching to carry out horizontal adjustment along direction shown in the arrow C, also can utilize another 18 and the driving motor 19 of attaching carry out vertical adjusting along direction B.

In order to drive tappet 14 and to drive in chattering type ground by brush 61 and for example cleaning element that cavernous body 62 is formed, as can being clear that especially from Figure 4 and 5, tappet 14 be through a crank driving mechanism 31 and with driving motor 32 transmissions ground bonded assembly.At this, on the transmission shaft 33 of driving motor 32, settled a crank 34, this crank be furnished with a crank pin 35 and inertial mass 34 '.Crank pin 35 here embeds in the groove that is slotted hole 37 shapes that processes on a liner plate 36.Liner plate 36 is parts of tappet 14, so tappet can carry out horizontal drive through crank mechanism 31.

Act on this tappet in order also can vertically to regulate simultaneously 14, one control of tappet cam 38, this cam can be driven by a belt gear 43, and tappet 14 then can utilize a slip ring 41 of being furnished with deflector roll 42 pivotally around 39 supportings of two bolts.For this reason, bolt 39 can be supported in the two boards 40 rotatably, and this two boards is sealing crank mechanism 31, by screw 57 they is coupled together.

The belt gear 43 of configuration is provided with an idler roller 46 for power cam 38, and it is guided by guiding roller 44 and 45, and these guiding rollers all are that transmission ground is connected with the transmission shaft 33 of driving motor 32 with cam 38.For tappet 14 can stably be abutted on the cam 38, disposed a compression spring 49 that is placed on the bolt 48, this spring a roller 50 that is close on tappet 14 at the one end bearing.Compression spring 49 on the free end that is supported on bolt 48, also be supported on the annex 47, this annex is fixed on the tappet 14.When tappet 14 by the rotation of cam 38 and around bolt 39 during to turning down, compression spring 49 makes and is tensioned, so tappet 14 is also led back according to the configuration of cam 38.In order to control each parts of clean-up device 11, disposed a control setup (in each figure, all not expressing), it for example comprises a microprocessor.This microprocessor utilizes

electrical motor

19 and 17 to regulate and control the vertical and horizontal motion of the driving of the tappet of vibration, hold-down arm 13 and the height adjustment and the driving of roller 26 and 22.In addition, this microprocessor is the driver train of may command escalator also, moves forward a step that ascertains the number so as to making escalator.Be provided with an interface cable for this reason.This cable can link to each other with a control input port of escalator 1.

In order to utilize clean-up device 11 to clean the pedal surface 3 and the end face 4 of each pedal step 2 of

escalator

1,11 needs of clean-up device are positioned in the petiolarea that sets out of escalator 1, as long as the control setup of clean-up device 11 and escalator 1 also is connected to each other.This all utilizes interface cable to realize.When escalator 1 is in shut down condition, the control setup of electrical motor is just so being controlled the power wheel 22 of clean-up device 11, make clean-up device move automatically, up to a sensor 55 because in fact sent a signal near pedal step 2, this sensor is placed on the axle 29 of roller 26, and it links to each other with control setup equally.Then, control setup starting escalator 1 is so that upwards operation of escalator.So clean-up device 11 are pulled to the position shown in Fig. 1, this motion at this moment can be supported by the transmission of roller 22.

According to another kind of scheme, along with the signal that sensor 55 sends, roller 26 is vertically released, clean-up device 11 then utilize power wheel 22 along the direction of escalator 1 by predetermined highway section of dislocation.Then, roller 26 is again so recalled, and makes conversioning wheel 29 be supported on the follow-up pedal step.Next pedal step with the same manner escalator 1 moves past, thereby makes clean-up device 11 also be in the position shown in Fig. 1 equally.

When escalator was stopped transport, horizontal adjustment that can be by hold-down arm 13 was removed foul on the pedal surface 3 with cleaning element 61; The perhaps vertical adjusting by hold-down arm 13 is removed foul on the end face 4 with cleaning element 62.

Carrying out under the situation of horizontal adjustment in order to clean pedal surface 3 especially, tappet 14 is realized vibratory movement, makes each cleaning element act on the same place of pedal surface for more than 61 time.This point drives crank mechanism 31 by electrical motor 32 and is realized.In this, the horizontal motion of vibration is equitant with a synchronous vibration perpendicular movement, so in a cyclic process, cleaning element 61 at first drops on the pedal surface 3, contact with pedal surface 3 then and recall a predetermined highway section, then be raised once more, be pulled back to the level point in the time of on being in pedal surface 3 once more.The horizontal component of above-mentioned vibratory movement only covers along the part of the pedal surface 3 of the service direction of escalator 1.In Fig. 1, A schematically represents the curve movement of the above-mentioned vibratory movement of cleaning brush 61.For clarity, curve A has specially painted lowly a step.

Carried out a kind of additional continuous horizontal adjusting owing to utilize the 17 pairs of hold-down arms 13 of driving motor on the screw rod 16, tappet 14 except doing vibratory movement also the service direction along escalator move backward, thereby foul and sediment are constantly removed away from the groove line profile of pedal surface.Guaranteed effective clean of the groove line profile of pedal surface 3 by vibratory movement.

For the end face 4 that cleans a pedal step, the signal that hold-down arm 13 response control apparatus send utilizes driving motor 17, along screw rod 16, moves towards the end face 4 of a step level 2.

The cleaning element that is designed to cavernous body 62 is used for cleaning end face 4.It is positioned on the intermediate member 51, and this intermediate member utilizes an articulated joint 52 to remain on pivotally on the tappet 14.By a gas spring 54, above-mentioned intermediate member 51 is pressed on the baffle plate 53.After cavernous body 62 touched end face 4, tappet utilized the driving motor 19 on the screw rod 18 to move up 14 this moments, so above-mentioned intermediate member 51 just can be followed the profile of end face 4, thereby made cavernous body 62 and end face 4 guarantee to realize best the contact.Look the difference of dirty degree, can utilize 62 pairs of end faces of cavernous body 4 to carry out the one or many clean as stated above.

After the clean operation process to pedal surface 3 and end face 4 finished, clean-up device just utilized power wheel 22 to move backward by control setup.Utilize conversion roller 29 that roller 26 is placed on the next

lower pedal step

2,26 on roller can utilize electrical motor 28 and tooth bar 27 to the certain length of bottom offset.So a kind of like this state occurs, as shown in Figure 3.At this moment, control setup sends a signal to the driver train of escalator again, the step so that escalator moves up.As initial process, at this moment clean-up device 11 are withdrawn into the position shown in Fig. 1 once more.Control setup sends a danger signal to the driver train of escalator 1, just can begin the cleaning course of next pedal surface or next end face.

At this moment, the motion of clean-up device 11 is monitored by the sensor of some.Sensor 55 and 56 illustrates in each accompanying drawing example of passing the imperial examinations at the provincial level.For example, sensor 55 is used to export a signal, when clean-up device close on around upper surface 4; Sensor 56 is used for detecting the distance from pedal surface 3.Other sensor for example is used for the lateral register of clean-up device 11, also can dispose, to be used for the automatic transposition of clean-up device 11.

The hold-down arm 13 that has tappet 14 and cleaning element 15 can move on in such position, and this moment, clean operation can utilize nozzle 63 (see figure 6)s to carry out.This clean operation can periodically be carried out, for example after clean is crossed step by user's predetermined number.Cavernous body 62 utilizes nozzle 63 to come that hydro-peening is clean in addition, can on a sleaker 65 it be extracted then.The washing lotion of coming out is collected in the collecting tank 64, and available pump is taken away or released in case of necessity.Sleaker 65 also can be used for the cleaning brush 61 of swiping, and cleaning brush is used to clean pedal surface 3.For this reason, control setup 11 is made a corresponding curve movement in advance for hold-down arm 13.Hold-down arm 13 is retracted into such height for this reason, makes cleaning brush obtain scraping on sleaker 65.After cleaning

element

61,62 is carried out clean, just can proceed clean operation by described mode to escalator 1.

Method at following situation has been described, promptly escalator is moved up by a pedal step 2 respectively by control setup.At the parts of correspondingly controlling clean-up device 11 specifically under

roller

22 and 26 the situation, when escalator whenever moves down by a pedal step, also can carry out said method after pedal surface of clean and end face.When raceway was carried out clean, clean-up device can use in the same old way, certainly the clean of end face had been saved.

Utilize clean-up device that the present invention proposes can to escalator or raceway realize special completely, full automatic thereby also be economic clean.The petiolarea that this clean-up device only need be positioned at escalator or raceway gets final product, and it can automatically carry out remaining clean operation.Specifically, when escalator is cleaned, by a kind of vibratory movement of the cleaning brush 61 that is exemplified among cleaning element such as the figure, even clean also can be guaranteed to obtain in the angular region between each end face 4 and the following pedal surface 3.
