Abstract

Using the cleaning apparatus there can be cleaned the inner surfaces of a glass lining which laterally covers the support structure of an escalator. A cleaning carriage is guided parallel to the top flange and the bottom flange of the support structure and is reciprocated by a cable drive in the direction of the escalator inclination between the support structure and the glass lining. A cleaning liquid distributor uniformly distributes cleaning liquid at the inner surfaces of the glass lining. A wiper blade is mounted at the cleaning carriage and presses against the inner surface of the glass lining. During the reciprocation of the cleaning carriage the wiper blade wipingly moves along the glass lining. The excess cleaning liquid and the cleaning liquid which accumulates during the wiping of the glass lining is received and drained by a lower one of guide rails at which the cleaning carriage is guided.

Description

Die Erfindung betrifft eine Reinigungseinrichtung für eine das Tragwerk einer Fahrtreppe oder eines Personenförderbandes seitlich abdeckende Glasverkleidung.The invention relates to a cleaning device for a glass covering which laterally covers the structure of an escalator or a conveyor belt for people.

In letzter Zeit werden aus architektonischen Gründen Glasverkleidungen nicht nur für die Balustraden sondern vermehrt auch für die seitliche Abdeckung der Tragwerke der Fahrtreppen geplant und teilweise auch ausgeführt. Ein Hauptproblem dieser Ausführung bringt die Reinigung, vor allem der inneren Flächen der Glasverkleidung. Es hat sich gezeigt, dass gerade diese inneren Flächen sich eher stärker verschmutzen als die äusseren. Durch das Abstreifen von Staub und Schmutz von den Schuhen der Passanten auf den Oberflächen der Stufen-Trittplatten gelangt mindestens ein Teil davon auch in das Innere der Fahrtreppe. Die durch das umlaufende Stufenband erzeugte Luftzirkulation im Innern der Fahrtreppe bringt es dann mit sich, dass sich Staubpartikel auch an den inneren Seitenflächen der Glasverkleidung ablagern. Aus diesem Grunde ist eine Reinigung dieser Flächen von Zeit zu Zeit erforderlich. Bis heute hat man dieses problem für die wenigen mit Glasscheiben verkleideten Tragwerke von Fahrtreppen so gelöst, dass die einzelnen Glasscheiben für die Reinigung entweder demontierbar oder auf- oder abkleppbar ausgeführt wurden. Der grosse Nachteil dieser Ausführung liegt darin, dess die Zugänglichkeit zu den schrägen Seitenteilen einer zwei Stockwerke miteinander verbindenden Fahrtreppe sehr schwer ist und, vor allem, wenn mehrere Fahrtreppen übereinander angeordnet und im Bereich der Etagen grosse Bodendurchbrüche vorgesehen sind, ohne zusätzliche Gerüste fast unmöglich wird. Bei zwei gekreuzt nebeneinander angeordneten Fahrtreppen ist die Zugänglichkeit zu den mittleren, einander direkt gegenüberliegenden Glastafeln noch schwerer und ein Auf- oder Abklappen der Glastafeln zum Reinigen der inneren Flächen überhaupt unmöglich. Dazu kommen die grossen Unfallgefahren welchen das Reinigungspersonal bei diesen Arbeiten ausgesetzt ist, und nicht zuletzt auch die vermehrte Gefahr von Glasbrüchen.Recently, for architectural reasons, glass cladding has not only been planned for the balustrades but also increasingly for the lateral covering of the supporting structures of the escalators. A major problem with this design is cleaning, especially the inner surfaces of the glass cladding. It has been shown that these inner surfaces become more polluted than the outer ones. When dust and dirt are wiped off the shoes of passers-by on the surfaces of the step tread plates, at least some of them also get inside the escalator. The air circulation inside the escalator created by the circumferential band of steps then entails that dust particles are also deposited on the inner side surfaces of the glass cladding. For this reason it is necessary to clean these surfaces from time to time. To date, this problem has been solved for the few supporting structures of escalators clad with glass panes in such a way that the individual glass panes for cleaning were either designed to be dismantled or designed to be towed up or down. The major disadvantage of this design is that it is very difficult to access the sloping side parts of an escalator that connects two floors and, especially if several escalators are arranged one above the other and large floor openings are provided in the area of the floors, without additional scaffolding is almost impossible . With two crossed escalators arranged next to each other, access to the middle, directly opposite glass panels is even more difficult and opening or unfolding the glass panels for cleaning the inner surfaces is impossible at all. In addition, there are the major accident hazards to which cleaning staff are exposed during this work, and not least the increased risk of glass breakage.

Der Erfindung liegt die Aufgabe zugrunde, eine preisgünstige Reinigungseinrichtung für die Flächen der seitlichen Glasverkleidung eines Fahrtreppen-Tragwerkes vorzuschlagen, welche bei jeder Fahrtreppe anordnung einsetzbar ist und bei welcher die Glasscheiben eder entfernt noch auf- oder abgeklappt werden müssen und mit welcher die Reinigung der Flächen der Glasverkleidung ohne Unfallgefahr für das Reinigungspersonal durchführbar ist.The invention has for its object to provide an inexpensive cleaning device for the surfaces of the side glass cladding of an escalator structure, which can be used with any escalator arrangement and in which the glass panes must be removed or opened or removed and with which the cleaning of the surfaces the glass paneling can be carried out by the cleaning staff without the risk of an accident.

Diese Aufgabe wird durch die in den Ansprüchen gekennzeichnete Erfindung gelöst.This object is achieved by the invention characterized in the claims.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass die Flächen der seitlichen Glasverkleidung des Fahrtreppentragwerkes gereinigt werden können, ohne dass für Reinigungspersonal ein Zugang zu diesen Flächen von der Fahrtreppen-Innen- oder -Aussenseite erforderlich ist, dass die Reinigung jederzeit, notfalls auch während des Betriebes der Fahrtreppe, durch eine einzige Bedienungsperson erfolgen kann und dass Unfallgefahr für Reinigungspersonal und Glasbruchgefahr durch die Reinigung komplett ausgeschaltet sind. Zudem ist jede Fahrtreppenanordnung auf der Baustelle möglich ohne Rücksichtnahme auf eine eventuell an der Fahrtreppe angebaute erfindungsgemässe Reinigungseinrichtung.The advantages achieved by the invention are essentially to be seen in the fact that the surfaces of the side glass cladding of the escalator structure can be cleaned without cleaning personnel having to have access to these surfaces from the inside or outside of the escalator, so that cleaning is possible at all times , if necessary also during the operation of the escalator, can be carried out by a single operator and that the risk of accidents for cleaning personnel and the risk of glass breakage are completely eliminated by the cleaning. In addition, any escalator arrangement on the construction site is possible without taking into account any cleaning device according to the invention that may be attached to the escalator.

Auf beiliegenden Zeichnungen ist ein Ausführungsbeispiel der Erfindung dargestellt, das im folgenden näher erläutert wird. Es zeigen:

  • Fig. 1: eine Seitenansicht der Fahrtreppe,
  • Fig. 2: einen Aufriss eines Reinigungswagens, und
  • Fig. 3: einen Schnitt A-A gemäss Fig. 1 durch einen Seitenträger des Tragwerkes.

  • 1: a side view of the escalator,
  • Fig. 2: an elevation of a cleaning trolley, and
  • 3 shows a section AA according to FIG. 1 through a side support of the supporting structure.

In der Figur 1 ist mit 1 das Tragwerk der Fahrtreppe bezeichnet. Der Obergurt des Tragwerkes 1 erhält die Ziffer 2, der Untergurt die Ziffer 3. Der schräge Teil des Tragwerkes 1 wird seitlich durch eine Glasverkleidung 4 abgedeckt, während der horizontale Oberteil 20 und der horizontale Unterteil 21 mit Stahlblechen verkleidet sind. Ueber dem Tragwerk 1 ist eine Balustrade 22 aufgebaut. Eine untere Antrittplatte der Fahrtreppe wird mit 24, eine obere Antrittplatte mit 25 bezeichnet. Zwischen dem Tragwerk 1 und der Glasverkleidung 4 ist ein Reinigungswagen 7 angeordnet, der auf Laufrollen 9 und einer Stützrolle 10 auf zugehörigen Führungsschienen schräg auf- und abwärts bewegbar ist. Der Reinigungswagen 7 wird über ein endlos verbundenes Zugseil 12 durch einen von einem Elektromotor 23 angetriebenen Seilantrieb 11 verschoben. Das Zugseil 12 wird um eine am unteren Ende der Fahrtreppe angeordnete Spannrolle 13 umgelenkt. Ein am Reinigungswagen 7 festgemachtes Wischerblatt wird mit 8 bezeichnet. In Fig. 2 ist der Reinigungswagen 7 in einem etwas grösseren Maßstab deutlicher dargestellt. Er läuft auf den unteren Laufrollen 9 auf einer U-förmigen Führungsschiene 6 und stützt sich mit der Stützrolle 10 auf eine obere Führungsschiene 5 ab. Am Reinigungswagen 7 ist ein gegen die Glasscheiben gerichtetes Wischerblatt 8 einstellbar befestigt. Seitlich neben dem Wischerblatt können für eine weitere Ausführungsvariante eine Schwammleiste 16 oder Sprühdüsen 17 vorgesehen sein. Durch das Zugseil 12 wird der Reinigungswagen beliebig hin- oder herbewegt.In Figure 1, 1 denotes the structure of the escalator. The upper chord of the structure 1 receives the number 2, the lower chord the number 3. The oblique part of the structure 1 is laterally covered by a glass panel 4, while the horizontal upper part 20 and the horizontal lower part 21 are clad with steel sheets. A balustrade 22 is built above the supporting structure 1. A lower step plate of the escalator is designated 24, an upper step plate 25. A cleaning trolley 7 is arranged between the supporting structure 1 and the glass cladding 4 and can be moved obliquely up and down on rollers 9 and a support roller 10 on associated guide rails. The cleaning carriage 7 is displaced via an endlessly connected traction cable 12 by a cable drive 11 driven by an electric motor 23. The traction cable 12 is deflected around a tensioning roller 13 arranged at the lower end of the escalator. A wiper blade attached to the cleaning trolley 7 is designated 8. 2, the cleaning trolley 7 is shown more clearly on a somewhat larger scale. It runs on the lower rollers 9 on a U-shaped guide rail 6 and is supported with the support roller 10 on an upper guide rail 5. A wiper blade 8 directed against the glass panes is adjustably attached to the cleaning trolley 7. A sponge strip 16 or spray nozzles 17 can be provided on the side next to the wiper blade for a further embodiment variant. The cleaning carriage is moved back and forth as desired by the pull rope 12.

Fig. 3 zeigt den zwischen der Glasverkleidung 4 und dem Tragwerk I laufenden Reinigungswagen 7 im Seitenriss. Am Untergurt 3 des Tragwerkes 1 ist die Führungsschiene 6 befestigt, auf der sich die Laufrollen 9 des Reinigungswagens 7 abwälzen. Am Obergurt 2 des Tragwerkes 1 ist die Führungsschiene 5 befestigt, an der sich die Stützrolle 10 abstützt. Ueber dem Obergurt 2 ist auf der ganzen Länge der Glasverkleidung 4 ein mit Oeffnungen versehenes Tragprofil 18 für die Aufnahme eines Bewässerungsschlauches 14 vorgesehen. Ein Sockelabdeckprofil 15 deckt das Tragprofil 18 und den Bewässerungsschlauch 14 ab und dient gleichzeitig als oberer Halter für die Glasverkleidung 4. Auf der Innenseite der Glasverkleidung 4 liegt ein Wischerblatt 8 auf, welches entweder mittels Schraubbolzen 19 einstellbar am Reinigungswagen befestigt ist oder als Ausführungsvariante mittels nicht dargestellten Federn am Reinigungswagen gefedert abgestützt ist. Der Reinigungswagen ist mit dem Zugseil 12 mit dem Seilantrieb 11 verbunden.Fig. 3 shows the cleaning car 7 running between the glass cladding 4 and the supporting structure I in side view. On the lower flange 3 of the structure 1, the guide rail 6 is fastened, on which the rollers 9 of the cleaning trolley 7 roll. At the top chord 2 of the structure 1 is the guide rail 5 attached, on which the support roller 10 is supported. Above the upper chord 2, a support profile 18 provided with openings is provided over the entire length of the glass cladding 4 for receiving an irrigation hose 14. A base cover profile 15 covers the support profile 18 and the irrigation hose 14 and at the same time serves as an upper holder for the glass cladding 4. On the inside of the glass cladding 4 there is a wiper blade 8, which is either attached to the cleaning trolley by means of screw bolts 19, or as a variant not shown springs is supported on the cleaning trolley. The cleaning trolley is connected to the traction cable 12 with the cable drive 11.

Die vorstehend beschriebene Reinigungseinrichtung arbeitet wie folgt:

  • In der Ruhestellung befindet sich der Reinigungswagen 7 der Reinigungseinrichtung im oberen Bereich der Fahrtreppe, für den Fahrgast unsichtbar hinter der Stahlblechverkleidung des horizontalen Oberteiles 20 abgestellt. Durch die Glasverkleidung ist von der Reinigungseinrichtung lediglich das obere Trum des endlos verbundenen Zugseiles 12 zu sehen. Bei starker Verschmutzung der Innenseite der Glasverkleidung 4 kommt die Reinigungseinrichtung zum Einsatz. Über der oberen Tragwerkskante befindlichen durchgehenden Bewässerungsschlauch 14 wird Reinigungsflüssigkeit nach kurzzeitiger Betätigung einer dafür vorgesehenen, nicht dargestellten Pumpe auf die Innenfläche der Glasverkleidung 4 aufgesprüht. Je nach dem Grad der Verschmutzung kann dieser Vorgang auch wiederholt werden. Die ablaufende Reinigungsflüssigkeit wird durch die U-förmig gestaltete untere Führungsschiene 6 aufgefangen, in den unteren Fahrtreppenteil und in eine Abwasserleitung geleitet. Der Reinigungswagen 7 wird nun gleichzeitig durch das vom Seilantrieb 11 bewegte Zugseil 12 gezogen und gegen das untere Fahrtreppenende gefahren. Dabei wird die Glasverkleidung 4 durch das an die Innenfläche gedrückte Wischerblatt 8 abgezogen. Der Reinigungswagen 7 wird von den Laufrollen 9 und der Stützrolle 10 durch die untere und die obere Führungsschiene 6, 5 so geführt, dass das Wischerblatt 8 mit gleichbleibendem Druck über die ganze Fläche der Glasverkleidung 4 bewegt wird. Das beim Abziehen der Glasscheiben sich sammelnde Wasser wird ebenfalls von der unteren Führungsschiene 6 aufgefangen und abgeleitet. Die Bewegung des Reinigungswagens kann mehrfach erfolgen.
The cleaning device described above works as follows:
  • In the rest position, the cleaning trolley 7 of the cleaning device is located in the upper region of the escalator and is hidden behind the steel sheet cladding of the horizontal upper part 20, invisible to the passenger. Through the glass cladding, only the upper run of the endlessly connected pull rope 12 can be seen from the cleaning device. If the inside of the glass cladding 4 is very dirty, the cleaning device is used. Cleaning liquid is sprayed onto the inner surface of the glass cladding 4 after a brief actuation of a pump, not shown, provided over the upper edge of the supporting structure. Depending on the degree of pollution, this process can also be repeated. The cleaning liquid running off is collected by the U-shaped lower guide rail 6, passed into the lower escalator part and into a sewage pipe. The cleaning trolley 7 is now simultaneously pulled by the pulling rope 12 moved by the cable drive 11 and moved towards the lower end of the escalator. The glass panel 4 is pulled off by the wiper blade 8 pressed against the inner surface. The cleaning carriage 7 is guided by the rollers 9 and the support roller 10 through the lower and the upper guide rails 6, 5 in such a way that the wiper blade 8 is moved over the entire surface of the glass panel 4 with constant pressure. The water that collects when the glass panes are removed is likewise collected and drained off by the lower guide rail 6. The cleaning trolley can be moved several times.

Es ist ohne weiteres denkbar, dass eine ähnliche Einrichtung auch für die Reinigung der äusseren Fläche der Glasverkleidung eingesetzt werden könnte.It is readily conceivable that a similar device could also be used for cleaning the outer surface of the glass cladding.

Anstelle des auf der ganzen Länge üher der Glasverkleidung verlaufenden Bewässerungsschlauches, oder als Zusatz zu diesem Bewässerungsschlauch, könnte ein am Reinigungswagen angeordnetes, eine oder mehrere Leitungen mit Sprühdüsen und eine Fumpe aufweisendes Gefäss für Reinigungsflüssigkeit vorgesehen sein, wobei während der Hin- oder Herbewegung des Reinigungswagens jeweils vor dem Wischerblatt laufend Reinigungsflüssigkeit auf die Fläche der Glasverkleidung versprüht wird.Instead of the irrigation hose running along the entire length of the glass cladding, or as an addition to this irrigation hose, one or more lines with spray nozzles and a pump with cleaning nozzles arranged on the cleaning trolley could be provided, during the movement of the cleaning trolley back and forth cleaning liquid is continuously sprayed onto the surface of the glass panel in front of the wiper blade.

Es ist auch denkbar, dass auf der ganzen Länge über der Glasverkleidung anstelle eines Bewässerungsschlauches eine Reihe von Sprühdüsen angeordnet werden könnte.It is also conceivable that a row of spray nozzles could be arranged over the entire length of the glass cladding instead of an irrigation hose.

Der Reinigungswagen könnte statt mit Laufrollen und Stützrollen auch mit Laufrollen und einer Gleit-Stützführung oder nur mit Gleitführungen ausgerüstet sein.The cleaning trolley could also be equipped with rollers and a slide support guide or only with slide guides instead of with rollers and support rollers.

Anstelle des mit dem Seilantrieb gekuppelten Elektromotors könnte auch ein Handantrieb vorgesehen werden, wobei es der Bedienungsperson durch den Einsatz einer nicht dargestellten mechanischen Umlenkvorrichtung ermöglicht wird, den Reinigungswagen mittels einer Handkurbel von der oberen Antrittplatte der Fahrtreppe aus zu bewegen.Instead of the electric motor coupled to the cable drive, a manual drive could also be provided, the operator being able to use a mechanical deflection device, not shown, to move the cleaning trolley by means of a hand crank from the upper entry plate of the escalator.
