Definitions

  • the present invention relates to an apparatus and a Process for cleaning a surface of a circumferential flat element, in particular an escalator or an escalator according to the The preamble of claim 1 and claim 10.
  • a jet nozzle by means of which the blasting material is blasted onto the wall to be cleaned, by an operator led.
  • the jet nozzle and operator are in a closed cabin equipped with a grating floor, through which the grit blasted onto the masonry and the loosened Dirt particles are drawn off and fed to a processing plant.
  • This way of working is not particularly pleasant for the operator, since this must be located directly in the work area penetrated by the blasting material.
  • such a cleaning process for escalators or conveyor belts not conceivable.
  • the object of the present invention is now a To provide an apparatus and a method with which cleaning in particular an escalator or an escalator with something blasted onto the surface Blasting material is made possible, the blasted material being blasted as far as possible should be completely sucked off again. This can be used of cleaning agents in liquid form.
  • an escalator or an escalator can be more easily Clean wisely and with little effort.
  • the holding device can easily between the two wall-shaped parts of the escalator or the conveyor belt, that form the railing, are clamped, the blasting head is by means of the carriage along a guide rail of the holding device transverse to Direction of travel of the escalator or the conveyor belt can be moved, being more advantageous Way drive means are provided.
  • the jet head can also be rotated about an axis of rotation in the Bracket held, which is substantially perpendicular to the surface to be cleaned is aligned, wherein the rotation takes place via a rotary drive.
  • the respective edge area of the escalator or the conveyor belt can be cleaned.
  • a control device is provided, on Beam head in its edge areas limit switch for emitting signals the control device are attached. Furthermore, it is advantageous at least one sensor is provided with which the degree of cleaning of the cleaned Streaking the surface is detectable, after which the jet head is moved to a next strip of the escalator or the conveyor belt to clean.
  • An advantageous embodiment of the invention is that a Another sensor is arranged on the blasting head, with which the joints of the composite flat elements that are cleaned are found can. If the joint is now in the area of the blasting nozzle of the blasting head comes, the control device causes a brief interruption of the Blasting. This prevents the blasting material from getting into the joints of the escalator or the conveyor belt can get.
  • the device for cleaning sits a surface of a circumferential flat element, in particular an escalator or conveyor belt 1 essentially from a compressor 2, a compressed air tank 3, a pressure blasting tank 4, a blasting head 5 and a suction and separation device 6 together.
  • a compressor 2 a compressed air tank 3
  • a pressure blasting tank 4 a blasting head 5
  • a suction and separation device 6 the compressed air from the compressed air tank 3 via a line 7 to the pressure jet tank 4 fed where the blasting material is mixed.
  • the compressed air with the blasting material via a further line 8 into the blasting head 5, in which the compressed air with the blasting material through a nozzle 9 on the to be cleaned Surface 10 is irradiated.
  • the blasting head 5 faces the surface 10 to be cleaned Circumferential area with a brush-shaped seal 11 equipped. This creates a cavity in which the Suction device 6 generates a negative pressure and thereby the blasting material with the dirt particles loosened from the surface are suctioned off via the line 12 becomes.
  • the blasting material can be in a known manner the blasted material thus processed is separated from the dirt particles can be used again.
  • FIGS. 2 and 3 there is the holding device 13 from a longitudinal profile 14, at each end of which a bracket 15 is attached, which is equipped with suction cups 16.
  • the bracket 15 are in in a known manner adjustable and fixable in the longitudinal direction of the longitudinal profile 14, whereby the holding device between two wall-shaped parts 17, which the form lateral boundary of an escalator or an escalator 1, clamped can be.
  • the longitudinal profile is parallel to the one to be cleaned Surface 10 of the escalator or the conveyor belt 1 clamped.
  • Guide rails 18 are fastened along the longitudinal profile 14. These guide rails 18 cooperate with guide elements 19 which are attached to a carriage 20 so that the carriage 20 in the longitudinal direction of the longitudinal profile 14 is guided.
  • a rack 21 is also fastened along the longitudinal profile 14, in which a gear wheel 22 engages, which is placed on a drive motor 23 is fixed in the carriage 20.
  • a bracket 24 is attached, in which a Axis of rotation 25 is used, to which the jet head 5 is attached.
  • the Rotation axis 25 is rotatable in a known manner and adjustable in height in the Bracket 24 held. In a known manner, the axis of rotation 25 can with respect the bracket 24 can be rotated by a rotary drive 26.
  • FIG. 3 shows the arrangement of the jet nozzle 27 in the jet head 5, the representation is schematic.
  • the further line 8 (not shown) (FIG. 1) is plugged on. Also visible is a suction port 28 on which the further line, not shown 12 is placed.
  • jet head 5 On the jet head 5 is on its surface 10 to be cleaned Circumferential area attached the brush-shaped seal 11.
  • the jet head 5 is in the assembled state of the holding device 13 so far lowered onto the surface 10 that the seal 11 is as full as possible rests on this surface 10.
  • Fig. 4 shows a schematic plan view of the jet head 5, the suction nozzle 28 and the upper part of the jet nozzle 27 and the axis of rotation 25 can be seen.
  • the jet head 5 is triangular, the jet nozzle 27 being arranged in the region of a tip of this triangle which also forms the front area of the jet head. This tip is formed by two sides 29 and 30 of the jet head 5, while the suction nozzle 28 is arranged on the base side 31 of the jet head 5 are.
  • a front one Limit switch 32 and a rear limit switch 33 are arranged on both sides 29 and 30 of the jet head 5 . These limit switches 32 and 33 are connected to a control device 35 via lines 34.
  • a sensor 36 is attached, each via a Line 37 are connected to the control device 35.
  • a further sensor 38 is attached to the tip of the jet head 5, which in turn is connected to the control device via a line 39 is.
  • the transverse joints of the escalator or the conveyor belt 1 are detected by the sensor 38, the control device 35 causes one Interruption of the blasting of the blasting material, if this corresponds Groove passes through the area of the jet nozzle.
  • the degree of cleaning can be determined by the sensor 36, which is on the base side 31 of the Beam head 5 is attached.
  • control unit 35 causes the blasting head to travel along the guide rail is shifted by activating the drive motor 23.
  • the displacement route corresponds to a dimension that is less than the width of the cleaned Strip. Then the next strip of escalator or conveyor belt 1 cleaned.
  • the rear limit switch 33 sends a signal to the control device 35, whereby the rotary drive is activated and the jet head 5 is rotated until the side 29 is aligned parallel to the wall-shaped part 17, as shown in Fig. 5A is.
  • the cleaning process is then continued, with the degree of cleaning is now determined by the sensor 36, which is in the range of Page 29 of the jet head 5 is arranged.
  • the wall-shaped part reaches 17 is, that is when the rear limit switch 33 and the front limit switch 32 emit a signal to the control device 35 and the sensor 36 the signal that the required degree of cleaning has been achieved, causes Control device 35 that the supply of the blasting material is stopped, the Beam head returns to the home position shown in Fig. 5B.
  • the escalator cleaning process can be started from this position or the conveyor belt 1 can be started on the other side, the process corresponds to that described above and the symmetrically arranged Monitoring elements are used until the appropriate End position is reached, shown in Fig. 5C.
  • the holding device can 13 can be removed again.
  • the sensors 36 determine the Degree of cleaning of the cleaned strip determine the time how long the jet head 5 is in a respective position for cleaning a strip should be located. This time can, for example, depend on the length of the Escalator or the escalator and its speed can be set.
