Definitions

  • the invention relates to the cleaning of escalators, and aims to obtain better results than at present.
  • the method according to the invention makes it possible to achieve a particularly high quality of cleaning, and in any case much superior to conventional methods where the automatic cleaning means are arranged at a level of the escalator, that is to say at a location where the path of the movable elements is horizontal and where only the top of the movable elements is accessible, the risers are therefore not cleaned and fouled fairly quickly taking into account their surface condition (most often polished metal), and the fact that they receive the drips of all the liquids arriving on the escalator.
  • said predetermined direction in which the movable elements circulate is that of descent, and it is by gravity that said automatic means of cleaning are applied to the movable elements, by means of a mounting these on a support suspended to swing on a fixed transverse member.
  • the movable elements Because the movable elements circulate in the direction of descent, they come into contact with automatic cleaning means, which can thus remain applied without difficulty, by the play of gravity alone, while if the movable elements circulate in the direction of ascent, they would slip away from the cleaning means, and it would be much more difficult to keep them applied to these elements.
  • said transverse member is made fixed by attachment to the fixed structure of the escalator located under the handrails thereof.
  • said transverse member is a jack adapted to be locked by force between the ramps of the escalator.
  • said transverse member comprises a bar at each end of which there is a clamping base adapted to be placed around the handrail of the escalator and to be maintained at the fixed structure of the latter. ci by pinching this structure below the handrail.
  • Such a transverse member has the advantage of being able to be used in the event that the escalators of the escalator are too fragile or of a nature which does not allow tight mounting of the jack.
  • said automatic cleaning means comprise a rotating brush, means for spraying a cleaning solution onto the brush, and means for scraping and suctioning the movable element after brushing.
  • Such cleaning means are in fact particularly well suited for treating the mobile elements of escalators.
  • said support comprises on each side a bearing articulated on said transverse member, a first arm, a first end of which is secured to said bearing and a second end of which carries one end of said rotary brush as well as an assembly comprising said scraping and suction means pivotally mounted coaxially with said brush so as to be biased towards said movable elements of the staircase, and a second arm, a first end of which is secured to said landing and a second end of which carries a counterweight.
  • said counterweight is formed by an injection and extraction assembly comprising a spray pump, a suction source and reservoirs for spraying liquid and aspirated liquid.
  • said support comprises a frame and suspension rods of said frame mounted in parallelogram, said frame comprising first arms at the end of which is mounted said rotary brush, and second arms at the end of which said means are mounted scraping and suction, the latter being provided to cooperate with the movable element located below that with which the rotary brush cooperates.
  • the first and second arms of the frame move parallel to themselves, so that the rotary brush and the scraping and suction means remain simultaneously in contact with the movable element that they are in. processing, the fact of shifting the brush and the scraping and suction means allowing particularly easy monitoring of the profile of the mobile elements.
  • the inventor has in fact discovered that a wet environment deposited on top of the moving elements of an escalator does not immediately flow from it, because this top is grooved, so that it is possible to recover the wetland relatively downstream of the location where the cleaning and scraping of the risers of the moving parts was carried out, at a location where this recovery can be easily carried out.
  • said recovery means is placed at a location where the trajectory of the mobile elements is horizontal and where only the top of these elements is accessible.
  • said automatic cleaning means comprise a rotary brush and means for spraying a cleaning solution onto the brush.
  • said support comprises a frame and suspension rods of said frame mounted in parallelogram, said frame comprising first arms at the end of which is mounted said rotary brush, and second arms at end of which is mounted said scraper element intended to cooperate with the movable element situated below that with which the rotary brush cooperates.
  • said scraper element is also mounted at the end of said second arms using suspension rods mounted in parallelogram.
  • the scraper element thus follows the profile of the risers of the movable elements, without being influenced by the movement of the rotary brush when it comes into contact with a riser of movable element situated above of the one with which the scraping element cooperates.
  • the device also comprises means for biasing said rods of the parallelogram on which the scraper element is mounted, so as to keep the latter applied against each riser of movable element succeeding itself in front of it.
  • the device 1 illustrated in FIG. 1 comprises automatic cleaning means formed by a rotary brush 2, nozzles 3 for spraying a cleaning solution on the brush 2, and a tool 4 for scraping and suctioning.
  • the nozzles 3 and the tool 4 are part of a pivotally mounted assembly coaxially with the brush 2 with a spring which biases it clockwise, so that the rear edge of the tool 4 is maintained applied to the surface next to which it is located.
  • the brush 2 is rotated by a drum motor integrated in its center.
  • the nozzles 3 are connected by a pipe 5 to a set 6 of injection and extraction which is also connected the scraper and suction tool 4 by a pipe 7 of larger section than the pipe 5.
  • the assembly 6 for injection and extraction is of a well known type, which includes a liquid reservoir to spray, a reservoir of aspirated liquid, a spray pump which feeds line 5, and a vacuum cleaner or suction source capable of treating dust and liquids, connected to line 7 and to the reservoir of aspirated liquid.
  • the automatic cleaning means 2, 3 and 4 are mounted on a support itself suspended from swinging on a transverse member 8 shown in FIG. 2.
  • This member 8 is a screw jack which comprises a threaded body 9 and a threaded rod 10 which each have at their end a shoe 11 intended to bear on the interior side of one of the ramps 12 of the escalator, the member 8 being secured to the fixed structure of the escalator by turning the body in the direction indicated by an arrow in FIG. 2, until it is forcibly locked between the ramps 12.
  • the transverse member 8 ' is formed by a bar 13, advantageously telescopic to be able to adapt to the different widths of escalator, at each end of which is a clamping base 14 which can be arranged around one of the handrails 15 of the staircase as shown in the drawing, the tightening of the threaded rods 16 allowing the transverse member 8 'to be maintained on the ramps 12 by pinching them below the handrail 15.
  • the support on which the cleaning means 2, 3 and 4 are mounted has on each side a bearing 17 articulated on the transverse member 8, with a bent arm 18, one of the ends of which is secured to the bearing 17 while the other end carries one of the ends of the brush 2 and of the swivel assembly of which the nozzles 3 and the scraper and suction tool 4 are part, and with a second arm 19 one end of which is secured to the bearing 17 while the other end carries the assembly 6 which forms a counterweight applying the cleaning tools to the surface facing which it is located.
  • the transverse member 8 is arranged so that the automatic cleaning means 2, 3 and 4 are opposite the movable elements 20 of the staircase at a location where they have their riser 21 out (see FIGS. 4 to 12), so that, depending on the position of the mobile elements, the brush 2 is applied by the simple play of gravity on the top of one of the elements 20, as shown for example in FIG. 4, or on the riser of one of these elements, as shown for example in Figure 7.
  • the escalator is then started, with the mobile elements 20 which circulate in the direction of descent.
  • the support comprises a frame 23 and rods 24 for suspending said frame mounted in a parallelogram, this frame comprising horizontal arms 25 at the end of which is mounted a rotary brush 26 driven by a motor 27 by l 'through a belt 28, and downwardly inclined arms 29 at the end of which are mounted scraping and suction means 30 which are provided to cooperate with the movable element 20 located below that with which cooperates the rotary brush 26.
  • a roller 31 ' is provided to facilitate the cooperation of the means 30 with the movable element 20.
  • the injection and extraction assembly marked 6 in FIG. 1 is not on board the tilting part of the device, the shape of the latter and the weight of the engine 27 being sufficient.
  • the scraping and suction means 30 are connected to the injection and extraction assembly by a line (not shown) such as line 7, and the nozzles (not shown) for spraying a cleaning solution on the brush 26 are connected to this assembly by a pipe (not shown) such as the pipe 5, the two aforementioned pipes having a length sufficient to allow to easily dispose the injection and extraction assembly to side of the escalator.
  • the means 30 comprise a first element 31 oriented horizontally to scrape and suck up the risers 21 of the mobile elements 20, and a second element 32 oriented vertically to scrape and suck the top of these elements 20, the end of each of the elements 31 and 32 being formed by a flap 33 of flexible material.
  • the means 30 are illustrated in more detail in FIG. 15, where it can be seen that they are formed by two metal U-shaped profiles 34 and 35 on which are attached on each side flexible rubber flaps 33, an orifice 36 or 37 of placing the element 31 or the element 32 in communication with the suction source being provided respectively in the profile 34 and in the profile 35, with a flap 38 mounted tilting between the position illustrated in solid lines where it closes the orifice 37 and the position shown in broken lines where it closes the orifice 36, each of these positions being stable thanks to a small spring jack 39 disposed between the flap 38 and the oblique wall 40 which connects the sections 34 and 35 to form a triangular section duct in depression thanks to its connection with the suction source.
  • the passage of the flap 38 from one position to the other is done by means of the rods 41 and 42 which are each held by two curved leaf springs 43, the flap 38 passing from one position to the other in an appropriate manner when the means 30 come into contact with the top or with the riser of a mobile element 20 of the escalator.
  • FIGS. 16 to 18 Another variant, similar to that illustrated in FIGS. 13 to 15, is shown in FIGS. 16 to 18.
  • the support comprises a frame 123 and rods 124 for suspending said frame mounted in parallelogram, this frame comprising horizontal arms 125 at the end of which is mounted a brush 126 and downwardly inclined arms 129 at the end of which is mounted a scraper element 131 of the risers of the movable elements, designed to cooperate with the movable element 20 situated below that with which the rotary brush 126 cooperates (see FIGS. 17 and 18).
  • the scraping element 131 is in this case constituted by a flexible rubber flap 133 inserted by force into a longitudinal groove 134 of a bar 135.
  • each of these rods 136 is articulated in rotation, at one of its ends, on a bar section 137 fixed transversely to one of the longitudinal ends of the bar 135 while at their other end, these suspension rods 136 are pivotally mounted on articulations integrated in a housing 138, itself fixed to the end of a respective downwardly inclined arm 129.
  • a spiral spring (not visible), also integrated in the housing 138, is mounted on each of these articulations, so as to rotate the suspension rods 136 in a clockwise direction.
  • a single spiral spring can be provided on a single articulation, or spiral spring articulations at the four ends of the parallelogram, or a compression or traction mounted diagonally on two ends of the parallelogram.
  • the scraper element 131 can not only be applied against each riser of the movable element, and held in position, but also is not influenced by the application of the rotary brush 126 against the riser of the immediately upper movable element 20, which is not uniform over time taking into account the fact that this brush 126 is flexible and therefore crashes differently against the riser depending on the moment of the rocking movement of the support on the transverse member spotted 113.
  • the rotary brush 126 and the scraper element 131 are each applied against a respective riser parallel and relatively independently of each other.
  • the transverse member 113 is, in this variant, of the type of that bearing the reference numeral 8 and described in support of FIG. 2. It will therefore not be described further here.
  • a motor 127 is also provided for driving the rotary brush 126.
  • the injection and extraction assembly marked 6 in FIG. 1 is also not on board the tilting part of the device, the shape of the latter and the weight of the motor 127 being sufficient.
  • the motor 127 is fixed to a support plate 140, itself fixed, at its two longitudinal ends, to the suspension rods marked 124, the most distant from the rotary brush 126.
  • the drive of the brush 126 is carried out via a deflection pulley 141 on which are mounted the ends of two belts 142, 143.
  • the deflection pulley 141 is, for its part, supported by a bearing 144 fixed to the built 123.
  • transverse member 145 is also provided, similar to member 113, intended to be mounted next to the latter and on which is mounted, in transverse sliding, a rod 146.
  • This rod 146 is fixed to one of its ends. to the frame 123. It carries on either side of its mounting area 147 on the transverse member 145, springs 148, 149.
  • Such arrangements improve the conditions for crossing each passage of the brushes 126 from the riser above the movable elements and from above to the riser of the movable elements 20.
  • the spray nozzles 155 (see FIG. 17) of a cleaning solution (wet environment) on the brush 126, forming part of the automatic cleaning means, like the brush 126, are connected to an injection assembly and remote extraction 160, by means of a pipe 161, as can be seen in FIG. 18.
  • This assembly 160 mounted on casters is here arranged next to the escalator at its fixed lower landing.
  • This recovery means 170 comprises two counter-rotating brushes 171a, 171b, intended to be applied to the top of the movable elements 20, to dry the tops following one another under the brushes 171a, 171b. It also includes a smooth roller (not visible) onto which the wet medium recovered by the brushes 171a, 171b is sprayed, a scraping element (not visible) from the smooth roller and a wetland recovery tank, after scraping the smooth roller. .
  • the injection and extraction assembly 160 contains, for its part, a spray pump (not visible) intended to be connected to the spray nozzles 155 and a suction source (not visible) intended to be connected by means recovery 170 for sucking the wet medium falling in the recovery tank of this recovery means 170, as well as reservoirs (not visible) of liquid to be sprayed (here the cleaning solution) and of sucked liquid (here the wet medium sucked from the recovery means 170).
  • this injection and extraction assembly 160 and the recovery means 170 are commercially available (with, however, for the latter means, a width less than that of an escalator, and an absence of means of immobilization in relation to such a staircase).
  • the means 170 for recovering wetland is here disposed at the bottom landing of the escalator, at a location where the trajectory of the movable elements 20 is horizontal and where only the top of these elements is accessible, allowing optimal recovery of the wet environment, preferably the second top visible to from the bottom of the staircase, while the support is itself mounted to swing at a location where the movable elements 20 still have their riser extended, preferably at the first riser fully extended from the lower landing.
  • the recovery means 170 is immobilized relative to the horizontal trajectory of the mobile elements 20, using immobilization means specific to the present application of this means, in this case a bar 175, such as the transverse member 8 or 8 '.
  • the scraping element 131 is kept applied on the smooth riser of the movable elements 20 which succeed one another in front of it, so that the wet medium remaining on the riser of each mobile element 20, following cleaning by the rotary brush 126, is brought back by scraping on the top of the corresponding mobile element 20.
  • the recovery means 170 are also operated to dry the top of the movable elements 20 of the wet environment which is present and which comes in particular from scraping by the scraping element 131.
  • the scraping element 131 is itself located at a certain distance from the top of the movable element located below that of the one with which the rotary brush 126 cooperates, and therefore does not scrape the top of this mobile element.
  • the top of the latter is in fact dried downstream of cleaning by the brush 126 using the recovery means 170.
